Definition Waste gases from industrial production often have harmful effects on the environment and human health. Cleaning measures should be taken before entering the atmosphere to meet the requirements of exhaust emission standards. This process is called exhaust gas purification. Commonly used exhaust gas purification methods are: absorption, adsorption, condensation and combustion four. purification system A complete exhaust gas purification system is usually made up of five parts. They are gas collection devices (gas collecting covers) that capture pollution gases, pipes that connect the components of the system, purify devices that purify the polluted gas, and provide power for the flow of gas. The dyed chimney. Gas collector
The capture of pollutants usually refers to the control and collection of the airflow of pollutants emitted at the open parts of the equipment. Through effective capture of pollutants to ensure good production and living environment around, as far as possible to transport and purify the smallest amount of gas, the highest efficiency. The gas collecting hood is a device for capturing pollutants, and its performance has a direct impact on the technical and economic indexes of the local exhaust purification system.
The Conduit Pipe intake is an integral part of the exhaust gas pollution control system. The pipeline system is used to transport airflow in the purification system, and the equipment and components of the system are connected into a whole through the pipeline. The rational design, construction and use of pipeline system can not only give full play to the effectiveness of the control device, but also directly relate to the economic rationality of the design and operation. Purification equipment Gas purification service is the core part of the purification system. When the pollutants in the exhaust contain the most discharge standards, they must be purified before reaching the discharge standard before they can be discharged into the atmosphere. Ventilator
The fan is the power unit for gas flow in the purification system. Fans are usually placed behind the purification equipment to prevent fan wear and corrosion.
Chimney The chimney is the exhaust device of the purification system. As the purified gas still contains a certain concentration of pollutants, these pollutants diffuse, dilute in the atmosphere after the chimneys are discharged and eventually settle down to the ground. In order to ensure that the concentration of pollutants on the ground does not exceed the ambient air quality from the standard, chimneys must have a certain height. In addition, in order to ensure the normal operation of the exhaust gas purification system, according to the different purification objects, the necessary auxiliary equipment is often added to the purification system. For example, the cooling device, the waste heat utilization device when dealing with the high temperature gas, the pipe compensator that satisfies the heat expansion and contraction of the steel, the explosion-proof device for transporting the flammable and explosive gas, and the various valves used to adjust the balance of the air volume and pressure of the system, and the measuring instruments, the control instruments and the measurement of various parameters in the system. A support for supporting and fixing pipes and equipment, and a silencer for reducing the noise of fans.
