Waste gas purification device

Abstract

The invention relates to the field of environmental protection, and especially relates to equipment for washing and purifying a waste gas by a plant extract. A waste gas purification device comprises a waste gas charging flow adjustment device, a washing tower and a washing liquid recovery and input device, wherein the washing liquid recovery and input device is composed of a washing liquid collection and storage tank, a pressure adjustment pump, a main tube, valves, branch tubes and atomization tubes; a washing liquid in the washing liquid collection and storage tank is subjected to pressure adjustment by the pressure adjustment pump, then conveyed into the main tube, and conveyed into the plurality of atomization tubes of a tower body by the plurality of branch tubes after passing through the plurality of valves, and a plurality of washing liquid atomization areas are formed in the middle of the washing tower; the to-be-purified waste gas is conveyed to the bottom of the tower, and the gas is conveyed into the washing tower through the washing liquid recovery and input device and adequately contacted by the atomized washing liquid in the plurality of atomization areas during the process of flowing upwards, and harmful ingredients in the gas are absorbed by the washing liquid. The device disclosed by the invention does not use a filler and a gas-liquid exchange tower disc, and has a large gas-liquid exchange area, and adequate absorption and purification, so that the waste gas purification device disclosed by the invention has the advantages of being simple in structure, economical and practical, safe and reliable, and good in washing effect.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a device for washing and purifying waste gas with plant extracts. Background technique [0002] With the development of society, environmental problems have increasingly become the focus of people's attention. Air quality is a big problem that people must face in their lives. The reason for the deterioration of air quality is that a large amount of waste gas produced by industrial production is discharged into the air, and the purification of waste gas has become A necessary device for industrial production. Nowadays, air purification technology generally adopts processes such as water curtain dust removal and activated carbon adsorption of harmful components. The absorption tower is widely used in chemical industry and other industrial production fields for gas absorption and purification. Its structure is various, and the most used are packed tower and plate tower. Th...

[0002] With the development of society, environmental problems have increasingly become the focus of people's attention. Air quality is a big problem that people must face in their lives. The reason for the deterioration of air quality is that a large amount of waste gas produced by industrial production is discharged into the air, and the purification of waste gas has become A necessary device for industrial production. Nowadays, air purification technology generally adopts processes such as water curtain dust removal and activated carbon adsorption of harmful components. The absorption tower is widely used in chemical industry and other industrial production fields for gas absorption and purification. Its structure is various, and the most used are packed tower and plate tower. There are fillers and trays inside the tower, which have the disadvantages of large resistance, high cost, and heavy cleaning and maintenance management workload.

Moreover, these technologies need to consume a large amount of washing liquid, and the contact and absorption of waste gas and washing liquid is not sufficient, which makes the washing effect unsatisfactory. Finding an economical and reasonable washing process with ideal washing effect has become a very urgent problem in the field of environmental protection.
