Comprehensive treatment device for dust-containing waste gas

Abstract

The invention relates to the technical field of waste gas treatment, in particular to a dust-containing waste gas comprehensive treatment device which comprises a filter box and a water washing box, a cleaning mechanism is arranged on the inner wall of a filter cartridge, a collecting barrel is arranged on one side of the filter cartridge, a collecting assembly is arranged on the inner wall of the collecting barrel, and the collecting assembly comprises a transmission structure. According to the waste gas treatment device, waste gas obtained after water washing can be detected through the detection pipe, when laser signals emitted by the laser emitter are effectively collected by the laser signal receiver, it is judged that the waste gas is treated cleanly, if the waste gas is not treated cleanly, the waste gas is guided into the gas inlet pipe again through the backflow pipe, and then the waste gas is discharged. The laser signal is not stably received, so that a worker is reminded to replace clean water in the water washing tank and clean a filter screen and a filter cartridge in time, the intelligent degree is high, the waste gas which is not completely and cleanly treated is prevented from being directly discharged, and the treatment effect on the waste gas containing dust is good.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a comprehensive treatment device for dust-containing waste gas. Background technique [0002] With the development of society, more and more factories are established and start production. Some factories produce a lot of dust-containing exhaust gas during the production process, such as cement factories, flour mills and marble production and processing plants, etc. The dust-containing exhaust gas is not Light pollutes the environment and increases the dust content in the air, and people are prone to various diseases when breathing dust-containing exhaust gas. To solve the above problems, it is necessary to treat the dust-containing exhaust gas. [0003] However, in the existing technology, there are problems as follows: the existing dust-containing waste gas treatment method generally discharges the waste gas to the outdoor environment after filtering and other steps ...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing technology, there are problems as follows: the existing dust-containing waste gas treatment method generally discharges the waste gas to the outdoor environment after filtering and other steps during discharge, but as the use time of the equipment prolongs, the filter screen will be damaged. Blockage, turbidity of the washing liquid, resulting in a decline in the filtering effect. At this time, the dust content of the exhaust gas discharged after treatment is still high, and the purpose of effective dust reduction has not been achieved, and the dust content of the exhaust gas cannot be monitored and treated for the second time.
