Description

Dust removal device for dry-mixed mortar production plant

Technical Field

The utility model relates to an environmental protection dust removal technical field specifically is a dry-mixed mortar production factory building dust collector.

Background

The bag type dust collector is a dry type dust filtering device. It is suitable for trapping fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by the filtering action of the fiber fabric, after the dust-containing gas enters the bag type dust collector, dust with large particles and large specific gravity falls into the dust hopper due to the sedimentation of the gravity, and when the gas containing fine dust passes through the filter material, the dust is blocked, so that the gas is purified. Bag dust removal is an older dust removal technology. Applications began as early as the 80's of the 18 th century. Only some hanging bags are used at the time, and the working efficiency is low. In 1881 a mechanical vibration dust-cleaning bag dust collector of the German Betch plant began to be commercially produced. In 1954, HJHersey invented a reverse-spray type blowing ring ash removal technology, so that the bag-type dust remover realizes continuous operation of dust removal and ash removal, the treatment capacity is improved by multiple times, and the pressure of a filter bag is stable.
