Gas collection box for exhaust gas combustion system

Abstract

A gas collection tank used for an exhaust gas combustion system is disclosed. The gas collection tank comprises a gas collection tank body, a filter screen, a filter screen driving device, a filter screen cleaning box and warm-wind conveying pipes. The filter screen traverses the gas collection tank body and filters exhaust gas streams in the gas collection tank body. The filter screen driving device drives the filter screen to slide and move along a direction perpendicular to the air flowing direction in the gas collection tank body. The filter screen cleaning box is at one side of the gas collection tank body. The filter screen traverses the filter screen cleaning box exactly. The filter screen cleaning box is communicated with the warm-wind conveying pipes. Warm wind is supplied to the warm-wind conveying pipes and exactly ejected onto the surface of the filter screen. The gas collection tank is high in cleaning efficiency, thorough in cleaning, and capable of saving labor. High-temperature gas discharged from the exhaust gas combustion system and indoor air are mixed and adopted as a source of the warm wind, thus saving the energy, protecting the environment, and making the energy utilization rate high. The filter screen after being automatically cleaned can be used repeatedly, thus saving the filtration cost.

Description

technical field [0001] The invention relates to a waste gas combustion system, in particular to a gas collecting box for the waste gas combustion system. Background technique [0002] In the process of factory processing, especially in the process of chemical plant processing, a large amount of VOC gases will be produced. These VOC gases will cause air pollution. They need to be processed through the exhaust gas combustion system, and the treated clean gas can be discharged into the atmosphere. Since the VOC gas is discharged from the exhaust gas generating equipment, there are a lot of particles and residual glue mixed in it, which makes it impossible to process it in the furnace body of the exhaust gas combustion system, so it needs to be filtered before entering the furnace body, and these particles and residual glue With strong adhesion, it is easy to cause blockage of the filter device. It is necessary to clean the filter device in time. Usually, it is cleaned by washin...

[0002] In the process of factory processing, especially in the process of chemical plant processing, a large amount of VOC gases will be produced. These VOC gases will cause air pollution. They need to be processed through the exhaust gas combustion system, and the treated clean gas can be discharged into the atmosphere. Since the VOC gas is discharged from the exhaust gas generating equipment, there are a lot of particles and residual glue mixed in it, which makes it impossible to process it in the furnace body of the exhaust gas combustion system, so it needs to be filtered before entering the furnace body, and these particles and residual glue With strong adhesion, it is easy to cause blockage of the filter device. It is necessary to clean the filter device in time. Usually, it is cleaned by washing with water. However, it is difficult to thoroughly clean the residual glue by washing with water, which brings great difficulties to cleaning.
