Description

Technical Field

[0002] Waste gas purification mainly refers to the work of treating industrial waste gases such as dust particles, flue gas, odorous gases, and toxic and harmful gases generated in industrial sites. Waste gases emitted by industrial production often have harmful effects on the environment and human health. Purification measures should be taken before they are discharged into the atmosphere to make them meet the requirements of waste gas emission standards. This process is called waste gas purification. Traditional waste gas treatment devices have many disadvantages. The overall structure of the waste gas treatment device is fixed, and it is difficult to adjust and upgrade according to changes in waste gas composition, concentration and processing volume. The internal structure of the equipment treatment device is complex, and the components are closely related to each other. During installation, professional technicians need to spend a lot of time on debugging. During maintenance and repair, it is difficult to find the fault point, and replacing parts may require the disassembly of the entire system, resulting in long equipment downtime and affecting the normal production of the enterprise.
