Spraying type deep cleaning dust collector

Abstract

The invention discloses a spraying type deep cleaning dust collector. The spraying type deep cleaning dust collector comprises a filtering device, wherein an exhaust cavity is formed in the upper portion of the filtering device; a dust hopper is arranged on the lower portion of the filtering device; the bottom of the dust hopper is fixedly connected with a dust outlet; a plurality of filtering bags are arranged in the filtering device; an air inlet is formed in a side wall of the dust hopper; a dust cleaning device is arranged on the top of the exhaust cavity; an exhaust opening is formed in the right side of the exhaust cavity; the outside of the exhaust opening is connected with an exhaust device; and a spraying assembly is arranged on the right side wall of the dust hopper. The problemsthat the air speed of waste gas which enters the dust hopper is large and the air inlet is small, therefore, the waste gas which enters the filtering device is distributed unevenly, dust absorption quantities of different filtering bags are different, the dust collection period of the dust cleaning device to the filter bags is shortened, and energy dissipation of equipment can be increased; and the waste gas contains hard particulate matters, the particulate matters further have edges and corners, the hard particulate matters impact the filtering bags for a long time at a certain speed, the filtering bags can be damaged, and the service lives of the filtering bags are shortened are solved.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to a spraying type deep cleaning dust collector. Background technique [0002] The bag filter is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and uses the filter function of the fiber fabric to filter the dusty gas. When the dusty gas enters the bag filter, the dust with large particles and large specific gravity will When the air containing fine dust passes through the filter material, the dust will be blocked and the air will be purified. [0003] In the prior art: the bag filter includes an ash hopper, a filter device, an exhaust device, and a dust removal device. The upper port of the ash hopper is connected to one end of the filter device, and the other end of the filter device is connected to the exhaust device. The dust removal device is arranged on the...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a spraying type deep cleaning dust remover to solve the problem of uneven distribution of the exhaust gas entering the filter device due to the high wind speed of the exhaust gas entering the ash hopper and the small air inlet in the above background technology, resulting in different The amount of dust absorbed by the filter bag is different, which shortens the dust removal cycle of the dust removal device for the filter bag and increases the energy dissipation of the equipment; the exhaust gas contains hard particles and these particles have edges and corners. Impacting the filter bag will cause damage to the filter bag and cause the problem of shortening the service life of the filter bag
