Problems solved by technology

From the test results of the internal flow field of the bag filter, the flow rate of the bags away from the air inlet side is too large, which will inevitably lead to increased wear of these bags and affect the service life of the bags

Embodiment Construction

[0018] The accompanying drawings disclose the specific structures of the embodiments of the present invention without limitation, and the present invention will be further described below in conjunction with the accompanying drawings.

[0019] Depend on Figure 1 ~ Figure 3 It can be seen that the present invention includes a box body, a cloth bag 3, an air inlet 5, an air outlet 1 and an ash discharge valve 6. The box body is composed of an upper box body 2 and a lower box body 4, and the lower box body 4 is bucket-shaped. The central axes of the two air inlets are parallel to each other and arranged horizontally on both sides of the lower box 4. The central axis of the air inlet 5 forms a horizontal angle α with the wall of the upper box 2, and the range of the included angle α is: 30°≤α< 90°; at least two rows of cloth bags are distributed in the upper box body 2, and the cloth bags 3 in adjacent rows are aligned front and rear, and the ash discharge valve 6 is located at t...

Abstract

The invention relates to a bag type dust collector with bags in arithmetic arrangement, and the bag type dust collector comprises a tank body, bags, air flow inlets, an air outlet and a dust discharge valve. The bag type dust collector is characterized in that the tank body consists of an upper tank body and a lower tank body, the lower tank body is of a bucket shape, axes of two air flow inlets are parallel to each other and horizontally arranged at two sides of the lower tank body; a plane included angle alpha is formed between the axes of the air flow inlets and the wall face of the upper tank body, and the included angle alpha is more than or equal to 30 degrees and less than 90 degrees; and at least two rows of bags are distributed in the upper tank body, the bags in each row are in arithmetic arrangement toward the center in sequence, and the bags in adjacent rows are in line alignment front and back, and the row distance and line distance of bag walls are between 60 and 100mm.

Description

technical field [0001] The invention relates to a dust collector, in particular to a bag-type dust collector which has double oblique tangential inlets and each column of cloth bags is arranged in an arithmetic manner along the side of the inlet to the center. Background technique [0002] As the country's requirements for the emission concentration of air pollutants become more and more stringent, it is difficult for electrostatic precipitators to meet the emission requirements for particles with high specific resistance of fly ash and relatively low capture efficiency for fine particles. However, the dust removal performance of the bag filter is not affected by the specific resistance of the fly ash. The impact of emission concentration is also extremely limited. Therefore, it has become a development trend to transform the electrostatic precipitator into a bag filter. [0003] However, due to the uneven air flow of the bag filter, the dust filter load of the bag in the ...
