Design of Coke Oven Gas Purification Workshop
Coke oven gas (hereinafter referred to as COG) is one of the important energy sources in steelmaking, and it is also one of the important sources of air pollutant in industrial production. To reduce air pollution, it is necessary to process and purify coking gas. This paper introduces the design of Cog purification plant.
1. Frame structure and overall design
The purification workshop of coking gas is mainly composed of coal oven, purification system and foundation. The device shall be designed and manufactured in strict accordance with the relevant guidelines and production processes of coal oven and purification system. The frame structure of the whole workshop should ensure that the overall stability and seal are reliable, and there should be no serious local deformation or bearing failure. The overall design should meet the requirements of reliable, efficient and energy-saving production.
2. Purification System Selection
The purification system of coking gas mainly includes gas adsorption purification and catalytic combustion purification. The adsorption purification mainly uses rapid filter, bed type filter, activated carbon filter and so on. The catalytic combustion purification mainly adopts catalytic combustion tower and regenerative catalytic combustion tower. When designing, it is necessary to consider the adsorption capacity and purification effect of different purification systems, select suitable purification processes, and select the required number of purification lines.
3. Conveying System Design
The conveying system of Cog purification plant mainly includes gas pipeline, valve and instrument. The inner wall of the gas pipeline should be smooth and bright, in order to reduce the pressure loss in the production process and reduce the energy consumption of the project. In addition, the pressure rating, connection type, tube bending radius and other factors of the gas pipe should be considered when designing, and the valve should be selected according to the size of the flow.
4. Control System Design
The control system of the purification workshop of coking gas mainly includes ventilation system, dust removal system, temperature and humidity control system, etc., which can realize automatic, real-time and remote monitoring and control of the whole process. The control system should be equipped with reasonable sensors, controllers and actuators to ensure the stability and accuracy of the monitoring and control.
In summary, the design of coking gas purification plant should incorporate a large number of technical parameters and comprehensive considerations, so as to guarantee the safe, stable and efficient production of the plant.
