Smoke dust treating device

Abstract

The invention discloses a smoke dust treating device which is simple in structure, easy to implement and good in treatment and purification effect. The smoke dust treating device comprises a dust remover which is connected to the discharge flue outlet of a combustion apparatus, wherein the dust remover is connected with a purifying treating pond in which lime water is contained through a connecting pipe; a smoke vent is connected to the top cover of the purifying treating pond; the connecting pipe is connected with the outlet of the dust remover and extended into lower lime water in the purifying treating pond; SO2, SO3 and CO2 in smoke dust are treated and purified through the lime water in the purifying treating pond.

Description

technical field [0001] The invention relates to a smoke and dust treatment device. Background technique [0002] In people's life and production activities, combustion devices including various boilers, kilns, etc. are usually used, and these combustion devices will inevitably emit a large amount of smoke (flue gas) including coal dust, coke dust and toxic and harmful gases. . Smoke dust mainly contains solid suspended matter (TSP), benzene soluble matter (BSO) and benzopyrene (BaP), while the content of SO2 and CO2 in smoke dust is relatively higher, which may seriously endanger human health and pollute the environment. At present, there are many methods and devices for purifying smoke and dust. The methods mainly include: after the smoke and dust are actively drawn out by an induced draft fan, the smoke and dust are removed by water mist cleaning, filtering, absorption, etc., or treated by chemical methods; the equipment used mainly includes: Vertical and horizontal puri...

Problems solved by technology

At present, there are many methods and devices for purifying smoke and dust. The methods mainly include: after the smoke and dust are actively drawn out by an induced draft fan, the smoke and dust are removed by water mist cleaning, filtering, absorption, etc., or treated by chemical methods; the equipment used mainly includes: Vertical and horizontal purification equipment; the flue gas discharged from the combustion device is processed by criss-cross purification equipment; these methods and devices generally have corresponding effects, but the technological progress is endless, and the existing treatment There is also a need for improvement and improvement in the method and device. For example, some dust removal effects are not satisfactory. Although some purification methods and purification equipment can obtain better treatment effects, the process is too complicated, especially some methods that include chemical treatment. It even brings defects such as secondary pollution, or the structure of the processing equipment is relatively complicated, the cost is expensive, and the investment is large.
