Incineration is a high-temperature heat treatment technology, that is, with a certain amount of excess air and the organic waste being treated in the incinerator for oxidation and combustion reaction, the waste in the harmful and toxic substances in the oxidation at high temperatures, pyrolysis and destruction, it is a waste can be achieved at the same time harmless, minimization, resource utilization of the treatment technology It is a treatment technology that can realize the harmlessness, minimization and resourceization of waste at the same time.
The main purpose of incineration is to burn the waste as much as possible, so that the incinerated material becomes harmless and maximize the volume reduction, and minimize the generation of new pollutants to avoid secondary pollution. For large and medium-sized waste incineration plant, can simultaneously realize the waste reduction, complete incineration of toxic substances in the waste, as well as the recycling of waste heat generated by the incineration of these three purposes.
The incineration method can not only deal with solid waste, but also can deal with liquid waste and gas waste; not only can deal with municipal garbage and general industrial waste, and can be used to deal with hazardous waste. Hazardous waste in the organic solid, liquid and gaseous waste, often using incineration to deal with. In the incineration of municipal waste, but also often the waste incineration process before the temporary storage process of leachate and odor introduced into the incinerator incineration.
Incineration is suitable for the treatment of organic components, high calorific value of the waste. When dealing with combustible organic components of the waste content is very small, the need to add a large amount of fuel, which will make the operating costs higher. But if there are conditions to supplement the appropriate waste heat recovery devices, can make up for the above shortcomings, reduce the cost of waste incineration, so that the incineration method to obtain better economic benefits. Environmental protection incinerator main equipment introduction
1, the incinerator main system introduction
The whole set of treatment system consists of the following parts: combustion system, incineration system, dust collector system, electronic control system.
2, the incinerator feeding method
Because the incinerator belongs to the special, manual feeding method. Manually put animal carcasses into the incinerator. For safety reasons, feeding should be carried out when the fire is weak. The feeding port is equipped with an operating platform, which is convenient for feeding material operation and maintenance.
3, incinerator combustion system
Combustion system for the main equipment for the gas burner
Combustion system's role is to ignite the furnace and auxiliary materials incineration (when the material calorific value of the lower, can not maintain their own combustion), natural gas fuel and air in the burner head mixing combustion and combustion air and combustion can be adjusted through the combustion head to get the best combustion parameters, the combustion gas in the combustion head again, the combustion head to get the best combustion parameters. The recirculation of the combustion gases in the combustion head minimizes the emission of pollutants, especially nitrogen oxides (NOx). Fully automatic management of the combustion program, flame detection, automatic judgment and indication of faults and other functions. The burner is capable of automatic ignition under the control of the programmer. The burner has the functions of automatic ignition, fire extinguishing protection, fault alarm, etc. and the features of large flame intensity, stable combustion, good safety, and large power adjustment. The burner can manually adjust the air flow so as to change the flame size; the built-in regulator ensures the stability of the outlet air pressure; it can also adjust the gas volume size by adjusting the gas supply pressure.

Furnace body
Furnace body is made of refractory materials, thermal insulation materials, insulation materials masonry in the grate on the upper part of the cavity, the outer steel plate to prevent leakage of flue gases and to make the surface temperature of the furnace body is less than 50 ℃. There is an access door on the side of the furnace body, and the auxiliary ignition burner is also on the side. The furnace body is equipped with an operator's desk.
In the furnace chamber flue gas from the bottom upward flushing materials, materials in the moisture drying, so that materials in time to fire. And the front and rear arch refractory heat storage and radiation materials, thus ensuring the material combustion temperature. Prolong the residence time of the flue gas, so that the material and the organic matter in the fly ash combustion completely, improve the destruction rate of harmful substances.
The furnace body is lined with high-temperature refractory materials, the middle is heat-insulating materials, the outer layer is thermal insulation materials, which can reduce the heat loss of the furnace body and improve the incineration efficiency; the appearance of the steel plate as a protective layer to prevent leakage of air; the refractory materials used are our company and the Building Materials Research Institute*** with the development of an acidic flue gas corrosion-resistant, heat-resistant, high-strength refractory materials.
5, incinerator exhaust gas treatment system
Dust collector system
This program are used centrifugal dust collector - cyclone dust collector, the incineration of the flue gas dust removal. The dust collector system consists of three parts respectively: dust collector cylinder, inverted cone and exhaust duct. The role of the dust collection system is to collect the particles of dust contained in the flue gas produced by the incineration of materials, which is convenient for centralized cleaning, and at the same time, it can reduce the pollution to the atmosphere and play a role in purifying the environment.
The working principle of the dust collection system: the particles of dust contained in the flue gas produced by the incineration of materials in the powerful suction effect of the induced draft fan to the cyclone dust collector (commonly known as dust collection barrel). Cyclone dust collector is a device that utilizes the centrifugal landing principle to separate particles of dust from the airflow. The upper part of the cyclone dust collector is conical, when the dusty gas enters from the tangential direction of the inlet pipe on the upper side of the cylinder, it gets the rotating counteraction, separates the dust and discharges it from the exhaust pipe on the top of the cylinder, and the dust particles fall into the dust collecting cylinder from the bottom of the cone.
6, incinerator electronic control system
The power distribution cabinet includes: a full set of equipment power supply, the main power supply, a single unit of equipment, power supply control switch; a full set of equipment and a single unit of equipment, start-stop control and protection circuits, alarms, etc.; operating panels and so on. The use of centralized control, some of the equipment for the convenience of operation and observation set in the field control.
The realization of the manual operation of all equipment and control cabinet panel operation, the realization of the entire system monitoring, alarms and other functions to improve the reliability of the system control.
The most important function is to ensure the optimized control of different materials in different combustion processes, thus ensuring the full combustion of materials and eliminating the quality of flue gas. Optimized control of the burner also reduces the amount of oil used by the burner, resulting in a significant reduction in operating costs.
