Bag type dust collector with self-cleaning ability

Abstract

The invention aims at providing a bag type dust collector with a self-cleaning ability. The bag type dust collector comprises a filtering device; an exhaust cavity is arranged at the upper part of thefiltering device, and a dust hopper is arranged at the lower part of the filtering device; the bottom of the dust hopper is fixedly connected with an ash discharge hole; the filtering device is internally provided with a plurality of filter bags; an air inlet is formed in the side wall of the dust hopper; an exhaust hole is formed at the right side of the exhaust cavity; the exhaust hole is externally connected with an exhaust unit; a cleaning assembly is arranged on the right side wall of the dust hopper; the filtering device is internally provided with a vibration assembly. The bag type dust collector solves the problem that the exhaust gas entering the dust hopper is larger in wind speed and an air inlet is smaller, so that the exhaust gas entering the filtering device is unevenly distributed, the amount of dust absorbed by the different filter bags is different, the dust removal period of a dust removing device to the filter bags is shortened, and the energy consumption of equipment is increased; the exhaust gas contains hard particles, and the particles also have angular edges; the hard particles impact the filter bags at a certain speed for a long time, so that the filter bags are damaged, and the service lives of the filter bags are reduced.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to a bag-type dust collector with self-cleaning capability. 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 arra...
