Water curtain type smoke dust removal device

Abstract

The invention discloses a water curtain type smoke dust removal device in the field of dust removal equipment. The water curtain type smoke dust removal device comprises a tank body, wherein the tank body is sequentially provided with an exhaust opening, a liquid inlet pipe and a smoke inlet pipe from top to bottom, wherein two overflow plates are at least upwards arranged in the horizontal direction inside the tank body; the overflow plates are in vertical arrangement, and are positioned between a liquid inlet pipe and the smoke inlet pipe; an overflow opening is formed between each overflow plate and the inner wall of the tank body; the adjacent upper and lower overflow openings are formed in opposite directions. The water curtain type smoke dust removal device has the beneficial effects that a great amount of water is injected into the tank body through the liquid inlet pipe; the liquid surface submerges a pipe opening of the smoke inlet pipe inside the tank body; smoke to be discharged enters the water through the smoke inlet pipe; solid smoke dust in the smoke is precipitated in the liquid; harmful gas capable of being dissolved into the input liquid in the smoke can be absorbed; the primarily purified smoke comes out from the liquid surface and passes through a plurality of overflow plates to form a water curtain for further purification; the precipitation removal of solid smoke dust in the smoke is realized; the content of harmful gas in the smoke is reduced; the problem of serious environment pollution is fundamentally relieved.

Description

technical field [0001] The invention relates to the field of dust removal equipment, in particular to a water curtain type smoke dust removal device. Background technique [0002] With the progress of society, the development of industry is becoming more and more rapid. The large amount of smog emitted by the industrial field is an important source of serious air pollution. There are many kinds of pollutants discharged into the atmosphere by industrial production, including a large amount of nitrogen dioxide and sulfur dioxide in the smog. , hydrogen sulfide and other harmful gases, there are also some fine particles of solid smoke entrained in the smoke. [0003] At present, some large-scale factories have built tall chimneys as smoke exhaust equipment. Taking advantage of the characteristics of high-altitude air flow and low pressure, although some harmful gases discharged into the air with smoke can be drifted to places far away from the factory, reducing the impact on th...

Problems solved by technology

In this technology, the dedusting link that the dust-laden smoke passes through includes filter screen, adsorption layer and water mist dust removal. The smoke flows straight upwards and is discharged through the discharge port. The disadvantage of such a setting is that part of the dust-laden smoke is discharged from the discharge port through the gap between the water mist before it contacts the adsorption layer on the inner wall of the cylinder, resulting in poor dust removal effect and incomplete dust removal.
