1. Objective: To standardize the operation, ensure the normal operation of waste gas treatment facilities and prevent accidents.
2. Responsibilities: exhaust gas expert and workshop supervisor.
3. Overall requirements:
(1) During the production period, the exhaust gas collection system must be started to prohibit the disorderly discharge of exhaust gas.
(2) Chemicals should be added to the waste gas tower regularly to ensure its normal function.
(3) Direct discharge of untreated waste gas is prohibited in the workshop.
(4) Daily operation, maintenance and management shall be carried out by designated personnel.
4. Operating rules:
(1) Routine inspection and preparation before operation.
(2) Check whether all electrical components such as electric control cabinet, frequency converter and front-end equipment are normal.
(3) Check every day to ensure that there is no moisture and a lot of dust in the cabinet.
(4) Determine whether the relevant air valve and water valve are open.
(5) Whether the drugs are processed and whether the automatic dosing system is switched to automatic mode.
(6) Pull the pipeline valve corresponding to the exhaust fan to be operated to the fully open state.
(7) Select the automatic dosing function.
(8) First turn on the water pump %2C, and then turn on the fan.
(9) Make records of dosing, maintenance and maintenance.
5. Precautions:
(1) Exhaust frequency control, which defines and modifies the frequency setting value according to the running state of production process equipment.
(2) In the process of valve switching, it is forbidden to switch when the fan is running.
(3) Measures for safe operation of the system: Do not switch the fan at will. Do not change the pump at will.
(4) Under the normal operation of the system, the system cannot be stopped at will.
(5)PH setting index, fan operating frequency and dosing pump dosing flow cannot be changed at will.
6. Key maintenance parts:
(1) water pump (check the water leakage, the medicine is not easy to be too strong).
(2) Fans (regular electromechanical maintenance, FRP materials are more durable).
(3) Support (the filler has slag, so check whether the support collapses).
Second, how to operate the waste gas treatment equipment
1, installation preparation stage:
Check the equipment so that the installation process can proceed smoothly. In the process of transportation or unpacking, if the paint and antirust layer are found to be damaged, necessary repairs should be made. During installation, operations such as welding and gas cutting cannot be performed on the surface of the equipment to ensure that the internal structure is not damaged.
2. Test preparation stage:
After the installation, pipelines, instruments and other projects are all completed, the workbench should be cleaned up in time.
3. Commissioning stage:
After the preparation phase, the start-up test will be carried out.
4, daily operation stage:
After preparation and testing, it entered the normal operation stage. Operators should regularly check the equipment site every day, truthfully record the results, and summarize them with the operation records as the data for regular maintenance.
5. Later maintenance stage:
After the equipment has been put into operation for one year, it should be regularly maintained, which is to ensure that it will run without accidents within one year next year. In order to reduce downtime, inspectors and maintenance workers should try to operate other components at the same time if possible. If any abnormality is found in the inspection, it must be handled and solved in time.
