Dust removing and filtering equipment and dust removing process thereof

Abstract

The invention discloses dust removal and filtration equipment and a dust removal process thereof, and relates to the technical field of dust removal processes, particularly to dust removal and filtration equipment and a dust removal process thereof. According to the equipment, a flue gas trapping cover is connected to a water film dust removal device through a cooling flue channel, and the water film dust removal device is connected with a smoke eliminating and dust fall device and a spraying system; one end of the smoke eliminating and dust fall device is connected with a sludge pool and a water filtering pool through a mud-water separation device, and the other end of the smoke eliminating and dust fall device is connected with an air outlet through an induced draft fan; and a sludge treatment device is connected with the sludge pool, the water filtering pool is connected with a purified water cooling device, and the purified water cooling device is connected with the water film dustremoval device and the spraying system. By using the technical scheme is adopted, the equipment has the beneficial effects of remarkable dust removal effect, stability, reliability, capability of automatically circulating smoke eliminating, dust reduction and water purification, no need of manual duty treatment, further perfection and improvement of smoke eliminating and dust reduction process performance, saving of a large amount of transformation funds, improvement of the dust removal effect and wide application to industries such as electric power, water conservancy, iron and steel, chemical engineering and the like.

Description

technical field [0001] The invention relates to the technical field of dust removal technology, in particular to a dust removal and filtering device and a dust removal technology. Background technique [0002] In recent years, with the rapid development of the economy, metallurgical steelmaking electric furnaces and boilers fueled by raw coal have increased a lot. The air pollutants emitted by these furnaces have caused great harm to the surrounding environment. Therefore, removing particulate matter from the dusty gas to reduce The technology of its emission into the atmosphere is becoming more and more important. [0003] Dusty industrial waste gas may be generated from mechanical processes such as crushing, screening, conveying, and blasting of solid substances, or from processes such as combustion, high-temperature melting, and chemical reactions. The former contains dust with large particle size and the same chemical composition as the original solid substance, while t...

AI Technical Summary

Problems solved by technology

[0005] The traditional dust removal method is relatively simple, and there is often only one dust removal process, the dust removal effect is poor, and the emission value stipulated by the state cannot be reached, causing great pollution to the environment
