Environment-friendly device for removing waste gas and smoke dust

Abstract

The invention discloses an environment-friendly device for removing waste gas and smoke dust. The device comprises a box body, wherein the lower part of the box body is a dissolving sedimentation tank, and the upper part is an adsorption cavity; treating fluid is stored in the dissolving sedimentation tank; a waste gas heat exchange channel is arranged in the box body; the inlet end of the waste gas heat exchange channel is connected with a lampblack dust collecting device; the outlet end of the waste gas heat exchange channel is inserted into the absorption dissolving solution; two exhaust ports are formed in the adsorption cavity of the box body; one exhaust port is provided with a decompression exhaust filter; when the pressure in the box body exceeds a set value, the pressure reductionexhaust filter automatically exhausts gas in the box body, the other exhaust port is provided with a pressure stabilization air inlet filter, the pressure stabilization air inlet filter is connectedto a combustion device, and the gas in the box body is filtered and subjected to pressure stabilization and then sent back to the combustion device to be subjected to secondary combustion recycling. After the structure is adopted, the device has the advantages of simple and reasonable structure, convenience in operation and use, thorough treatment of waste gas and smoke, simple process, low treatment cost, good use effect and the like.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment, in particular to an environmental protection waste gas and dust removal device for treating waste gas and dust. Background technique [0002] At present, household gas stoves and industrial and mining enterprise heating equipment are important sources of ambient environment and air pollution. When the domestic gas cooker is in use, the combustion device heats the cooker, and the exhaust gas and dust generated are directly discharged from the room through the range hood without any treatment. Heating equipment in industrial enterprises will produce a lot of harmful substances such as waste gas, dust, and solid particles during the production process. Although most enterprises have waste gas and dust treatment devices, there are mainly spray washing methods, electrostatic dust removal methods, etc. The dust removal effect of these methods is not thorough enough. , there ...

AI Technical Summary

Problems solved by technology

Heating equipment in industrial enterprises will produce a lot of harmful substances such as waste gas, dust, and solid particles during the production process. Although most enterprises have waste gas and dust treatment devices, there are mainly spray washing methods, electrostatic dust removal methods, etc., and the dust removal effect of these methods is not thorough enough. , there are the following disadvantages: First, the structure is complex, divided into reaction towers, cooling devices, processing devices, etc., the cost is high, and the exhaust gas filtration effect is not very good. Generally, only particulate matter or harmful gases are filtered during exhaust gas filtration, and then directly discharged , resulting in the filtered waste gas still not fully up to the standard; second, it is troublesome to replace and maintain the complete set of equipment, if the filter device is not replaced for a long time, it will cause the filter device to block and greatly reduce the treatment effect; third, the filtration efficiency is low and the discharge temperature is high

There is no good solution to the problems of environmental and air pollution and energy waste during the use of household gas stoves and industrial and mining enterprise heating equipment.

In response to the above problems, many manufacturers and people of insight have developed and developed, but so far no ideal products have come out.
