Blowing silencing tube

Abstract

The invention provides a blowing silencing tube, which is applied to a bag dust collector. The blowing silencing tube comprises a metallic pipe; ventilation holes which encircle side faces of the metallic pipe are arranged on the side faces of the metallic pipe from top to bottom; and the total area of the ventilation holes is 1-3 times of that of a blowing nozzle port. The blowing silencing tube can assist a blowing system of a dust collector, so that the dust collector can have lower dust-removing noises in a dust-removing process and the surface of a bag is subjected to even dust-removing and even stressing.

Description

Technical field [0001] The invention relates to the field of bag dust collectors, in particular to an injection system in the dust collector, and the invention is an auxiliary device for the injection system of the dust collector. Background technique [0002] The bag filter is the most common type of environmental protection equipment. Due to its simple structure and principle and low requirements on process parameters, it is still the most popular type of dust collector. [0003] For the conventional bag filter, its general working principle is as follows: In each air filter chamber of the dust collector, there are multi-filter air bags, and the dust gas enters the air filter chamber from the air inlet below the air filter chamber and enters the bag. During this process, the dust particles are filtered by the outer surface of the bag and adsorbed on the outside of the bag. After entering the bag, the filtered gas enters the cavity above the air filter chamber through the o...

Problems solved by technology

[0005] In the above structure, there is such a problem that the blowing nozzle is a short metal tube, such as image 3 As shown, the blowing nozzle 2 is facing the opening end above the cloth bag, when image 3 When the high-pressure gas indicated by the arrow is ejected rapidly from the blowing nozzle 2, it will expand rapidly at the port of the blowing nozzle 2, which will cause a large air explosion noise, making the dust collector have a large noise when cleaning dust , causing noise pollution to the surrounding environment; moreover, the expansion speed of the high-pressure gas is the largest at the nozzle 2 port, which makes the pulse force on the upper part of the bag significantly greater than the pulse force on the lower part, which causes the surface of the bag to be clean The problem of uneven gray and uneven force
