Dry/wet composite dedusting system

Abstract

The invention relates to the technical field of facility dedusting systems, particularly a dry / wet composite dedusting system. The dry / wet composite dedusting system comprises a pulse backflush filter element deduster and a water-curtain deduster, wherein the pulse backflush filter element deduster comprises a dedusting channel and a filter element dedusting mechanism which are connected to the upper part of the pulse backflush filter element deduster, and a dedusting pipeline outlet which communicates with one side of the filter element dedusting mechanism; and the water-curtain deduster comprise a water tank and a filter structure which sequentially communicate with each other from bottom to top, a water curtain system and a water curtain channel outlet arranged on the upper part of the water-curtain deduster. The dry / wet composite dedusting system can ensure the content of dust discharged into the air to be less than 1mg / m<3> which is lower than the national discharge index requirement; and the dry / wet composite dedusting system does not need to design or manufacture the chimney, is especially suitable for working spaces with higher environmental requirements, and has the advantages of wide adaptability, low discharge index, high stability and reliability, and the like.

Description

technical field [0001] The invention relates to the technical field of equipment dust removal systems, in particular to a dry-wet composite dust removal system. Background technique [0002] Today, the requirements for environmental protection are getting higher and higher, and the emission of equipment must at least meet the national standard or even zero emission. Therefore, there are more and more environmental protection equipment in various fields. In the field of shot peening (sand) treatment, shot peening (sand) treatment has been used as a processing technology for improving the fatigue strength of metal parts and improving the mechanical properties of the workpiece surface for decades. The process of shot blasting (sand) processing is complex and highly automated. Its processing equipment is a high-tech system integrating information technology, electronic technology, automation technology and manufacturing technology. [0003] In the shot blasting (sand) processin...

Problems solved by technology

[0004] The environmental protection device of the shot blasting equipment in the prior art often adopts a dust collector in the form of a dry filter element, and then directly discharges it into the atmosphere through the chimney. On the surface, the discharge of the equipment may meet the national standard, but the final discharge of the atmosphere The dust in the dust falls into the surrounding environment. If things go on like this, it cannot meet the requirements of sustainable development. Therefore, it is necessary to develop a dry-wet composite dust removal system to achieve the purpose of reducing the emission standard of the equipment and even achieving zero emission.
