1) Production characteristics
Coking plant generally consists of coal preparation, coking, recycling, refined benzene, tar, other chemical refining, laboratory and repair workshops. Among them, the laboratory and repair workshop is an auxiliary production workshop.
The task of the coal preparation workshop is to supply the cokemaking workshop with the coal that meets the quality requirements in time. Coking workshop is the main workshop of coking plant. The production process of the coking workshop is as follows: after taking coal from the coal storage tower, the coal loading truck is transported to the upper part of the carbonization room which has been pushed empty to load coal into the carbonization room, the coal is turned into coke through high temperature dry distillation, and release the barren gas to be piped to the recycling workshop; the coke will be pushed out of the carbonization room by the coke pusher, and then fall into the coke-extinguishing truck after passing the coke stopping truck, which will be sent to coke quenching tower to quench the coke; after that, it is unloaded into the cool coke platform from the coke-extinguishing truck, which will evaporate the excess water and further cooling, and then sent to the screening screen by the conveyor belt. After that, the coke is unloaded from the coke quenching trucks into the cooling platform to evaporate the excess water and further cool down the coke. The recycling workshop is responsible for pumping, cooling and absorbing various primary products from the barren gas generated in the coke oven.
2) Coking safety production technology and accident prevention measures
1) Fire and explosion prevention. All fire and explosion prevention measures are to prevent the production of combustible (explosive) mixtures or to prevent the generation and isolation of sufficient intensity of activation energy to avoid stimulation of combustible mixtures of combustion, explosion. To this end, it is necessary to clarify how combustible (explosive) mixtures and activation energy is produced, as well as measures to prevent their production and proximity to each other.
Some combustible (explosive) mixture formation is difficult to avoid, such as flammable liquid storage tank upper space on the existence of combustible (explosive) mixture. Therefore, before filling the material, to the storage tank first inert gas (such as nitrogen), exhaust vapor to avoid the above phenomenon. In addition, the use of floating roof tanks can also be avoided to produce combustible (explosive) mixtures. Other abnormal formation of combustible (explosive) mixture of causes and preventive measures are as follows:
⑵ leakage. Leakage is a common cause of combustible (explosive) mixtures. Leakage of combustible gases, flammable liquids and liquids with temperatures exceeding the flash point will produce combustible (explosive) mixtures in the area of leakage or leakage on the liquid surface. There are two main causes of leaks:
One is the presence of holes or cracks in the equipment, vessels and piping itself. Some of them are caused by poor quality of equipment manufacturing, and some of them are caused by long-term disrepair and corrosion. Therefore, all processing, handling, production or storage of combustible gases, flammable liquids or temperatures exceeding the flash point of combustible liquids equipment, tanks and pipelines, before being put into use must be accepted. In the process of use should be regularly checked for tightness and corrosion. Coking plant, many materials contain corrosive media, should pay special attention to the anti-corrosion treatment of equipment, or the use of corrosion-resistant materials.
Second, improper operation. Relatively speaking, this type of cause of leakage accidents caused by defects than the equipment itself to some more. As a result of negligence or operational errors caused by running oil, running gas accidents are many. To prevent the occurrence of such accidents, in addition to the requirements of strict standardization of operations, but also must take measures to prevent overflow. Coking Safety Regulations, flammable, combustible liquid storage tanks should be set up in the area of the fire embankment, fire embankment in the volume shall not be less than half of the total storage tank above ground, and shall not be less than the maximum storage tank above ground part of the storage capacity. The sewer in the firewall through the firewall shall be equipped with a gate. This gate shall be opened only when the water is released and shall be closed after the water is released.
3) Discharge. Coking plant many equipment are equipped with a dispersion pipe, processing or storage of flammable, combustible materials, equipment or storage tanks, dispersion pipe dispersion of gas (vapor) body itself is a combustible (explosive) mixtures, or released after mixing with the air to become a combustible (explosive) mixtures. Coking Safety Regulations stipulate that the dispersing pipes should be centralized and purified according to the types of gases and vapors to be dispersed before dispersing. The outlet of the discharge pipe for dispersing toxic and combustible gases should be more than 4m above the equipment and neighboring buildings. Combustible gas discharge outlet should be equipped with a fire retarder.
(4) dust and poison prevention. Coal dust is mainly generated in the process of coal loading and unloading, transportation and crushing, etc. The main dust-producing points are the coal yard, tipping machine, coal pit, conveyor belt, transfer station and crushing, pulverizing machine, etc. Generally, the coal yard is sprayed with covering agent. Generally, the coal yard adopts measures such as spraying covering agent or spraying water during loading and transportation to reduce the concentration of dust. Conveyor belt and transfer station mainly rely on the installation of conveyor belt through the profile, local or overall closed dust cover to isolate and capture coal dust.
Crushing and pulverizing equipment and other dust-producing points should be strengthened airtight suction, the installation of bag dust removal, wet dust removal, ventilation and other devices to reduce the concentration of coal dust.
In the coking plant, carbon monoxide exists in the gas, especially in the blast furnace gas used for coke oven heating carbon monoxide content of about 30%. Coke oven basement, flue pass contour gas equipment, valve opening and closing frequently, very easy to leak gas. Therefore, the gas equipment must be regularly inspected, timely maintenance, flue contour of the poor gas valve should ensure that it is in a negative pressure state.
In order to prevent hydrogen sulfide, hydrogen cyanide poisoning, coking plant should be set up desulfurization, de-cyanidation process facilities. In the past, only city gas is desulfurized in China, and metallurgical enterprises are generally not desulfurized. As for cyanide, generally only from part of the final cold water or ammonia cyanide production of yellow blood salt. With the improvement of the awareness of the seriousness of pollution, in recent years, the coking plants have begun to pay attention to the desulfurization of coal gas and cyanide. In order to prevent hydrogen sulfide and hydrogen cyanide poisoning, vaporizing ammonia system discharge pipe should be located in the downwind side of the operation.

Factory-level safety education assessment after passing the allocation to the workshop after the workshop safety education, qualified again after the shift safety education.
Only factory level, workshop level and.
3. What are the main tasks of production safety in coking enterprises
1. The warning signs and safety signs of the site posts shall not be moved arbitrarily.
2, the site ground level, rain and snow weather to take anti-skid measures; all channels, walking ladders, pavement should be unobstructed. 3, often check the platform, railings, aerial platforms, ladders must be intact; all dark ditch cover is complete and intact.
4, site lighting must be intact, defective lighting must be restored in a timely manner. 5, fire equipment, indoor steam fire extinguishing equipment and alarm devices must remain intact, prohibit the removal for other purposes, and have a person to keep.
6, the operation as far as possible to choose to stand in the wind, in order to prevent poisoning. 7, the pump, motor and other equipment for maintenance, do not wear gloves to prevent being involved.
8, prohibited in the equipment, piping and operating room baking clothes. 9, it is strictly prohibited from high to the ground to throw tools, materials, ropes and other debris, if necessary, should be set up a person to monitor.
10, prohibit the use of rags, sticks and other similar materials to block steam, gas or other liquid piping and equipment. 11, with a rubber hose to send steam blowing, rubber hose fixed with a card, not wire or rope binding.
12, found hidden danger timely measures and report; the hidden safety hazards should be rectified or monitored in a timely manner.
4. Coking plant pre-shift meeting to emphasize the safety of what
a, realistic situation, play its foresight The so-called foresight, is to foresee in advance what may be about to happen.
As the saying goes: "Preventive shots should be taken in advance", to make the pre-shift meeting meet the actual situation, with foresight (each post has different characteristics), the team leader in the acceptance of the task, you must understand the relevant safety matters, the upcoming operation of the site for a site visit to check the safety of the equipment protection device is good, found abnormalities in a timely manner through the shift, and the safety of the equipment. Found anomalies, promptly inform the workers through the pre-shift meeting, so that workers have a clear goal, dry with the direction of the safety system developed by the enterprise to each employee, so that it is in the acceptance of the work task at the same time, but also received a pre-service safety education for the class will be the completion of the work task, the quality standard escort. Admittedly, the enterprise production will have safety accidents, but look at each accident, analyze the reasons are often accidental with inevitability, most of the workers in the usual operation of the habitual violation of the rules, and over time into a catastrophe.
Therefore, the pre-shift meeting in the safety warning party foresight more knock on the alarm is very necessary. Second, highlight the key part, play its timeliness Pre-shift meeting time is short, to play its timeliness, must seize the focus, speak the key part, so that workers clearly understand to pay attention to the place, can not eyebrows and beard, resulting in workers can not grasp the focus, lose the center of gravity of the work.
Both waste of time and can not achieve the desired effect. The language is simple and concise, focusing on the effect of the pre-shift meeting.
Maximize the subjective initiative of each employee, so that some of the management system into the conscious behavior of each employee, so that the tangible management system into an invisible line of defense in the minds of employees. Third, people-oriented concept, play its flexibility Practice has proved that "a people-oriented, safety for the day" safety concept in the pre-shift meeting has an important role.
Carefully analyze those accidents that take away countless lives, how many of them start to step when unauthorized command, unauthorized operation of the operation caused by the evil consequences? How many are not our disregard for life, the pursuit of the momentary interests of the punishment? To a certain extent, unauthorized operation and suicide in different ways, but the consequences are the same; unauthorized command and the means of robbery and murder are different, but the effect is the same; disregard for safety hazards and see the difference between death and rescue? I believe that as long as we genuinely care for the lives of workers, regard life as the first, everything from the perspective of life to consider, violation of the rules and phenomena will be a substantial decline in the hope of survival will rise dramatically. Therefore, the pre-shift meeting should pay attention to people-oriented.
Of course, with the change of innovative forms, the staff pre-shift meeting can be based on their own characteristics, to play its flexibility. For example, the use of pre-shift meeting to recite the concept of enterprise, held a safety oath, tell a safety story, etc., so that the workers move up, spend little time, may produce unexpected results.
In short, in the production safety of workers give full play to the role of the pre-shift meeting, strengthen the safety awareness of workers, activate the workers "to be safe" to "I want to be safe" intrinsic motivation, and really play an important role in the process of construction of team safety. The company is also a leader in the safety construction of the workgroup. The first step in the process is to make sure that you have the best possible chance of getting the job done.
