The purpose of waste gas treatment is to control the industrial waste gas such as dust, flue gas, malodorous gas and toxic and harmful gas produced in industrial places.Common waste gas purification includes factory dust and waste gas purification, workshop powder waste gas purification, waste gas odor purification, chemical waste gas purification and so on.

Exhaust emissions from industrial processes often have harmful effects on the environment and human health.Before being discharged into the atmosphere, purification measures should be taken to make it meet the requirements of exhaust emission standards.This process is called waste gas treatment.The common methods of exhaust gas purification are condensation method and combustion method.

And a complete waste gas treatment system, generally consists of five parts.They are exhaust gas collecting devices (collecting hoods) that collect polluting gases.They connect the pipes of each component of the system to purify the polluted gas, provide a fan to power the air flow for exhaust treatment, and make full use of the chimney with the ability of air diffusion and dilution to reduce pollution.

Pollutant collection usually refers to the control, partial discharge of air streams containing pollutants.Through the effective collection of pollutants, waste gas treatment to ensure the surrounding, as far as possible to reduce the throughput of gas, waste gas collection device economy directly affects the technical indicators of its waste gas collection system.

Waste gas treatment of waste gas pollution control system in an indispensable component.It is used for conveying airflow in the purification system, and the equipment of the system is connected as a whole through pipes.The construction and use of pipeline system directly affect the economic rationality of design and operation.

Gas waste gas treatment and purification equipment is when the pollutant content in the waste gas exceeds the emission standard, it must be purified before it can be discharged into the atmosphere.The fan is generally arranged behind the purification equipment to prevent wear and corrosion of the fan.The chimney is the exhaust device of the exhaust gas treatment and purification system.Because the purified gas still contains a certain concentration of pollutants, it will diffuse in the atmosphere and eventually settle on the ground.In order to ensure the surface pollutant concentration, do not exceed the ambient air quality standards.

In addition, the waste gas treatment according to the different purification objects, in the purification system to increase the necessary auxiliary equipment, cooling device and waste heat utilization device, shrinkage changes of the pipeline compensator.Explosion-proof device for exhaust gas treatment and transportation of flammable and explosive gas, various valves and measuring instruments for regulating the air volume and pressure balance of the system, control instruments and measuring holes for various parameters in the measuring system, fan support and fixed pipes and equipment silencer device.
