Description

Modularized industrial dust remover

Technical Field

The invention relates to dust removing equipment, in particular to a modularized industrial dust remover.

Background

Currently, bag type dust collectors are widely used in industry in purifying dust-containing gases produced in industries such as metallurgy, mining, chemical industry, cement, power generation, grain processing and the like. The working principle of the bag type dust collector is that dust-containing gas is introduced into the dust collector and is led to permeate through a filter bag arranged in the dust collector, dust particles are intercepted and left on the surface of the filter bag to form a dust layer, and clean air smoothly flows out of the dust collector through the filter bag.

According to different directions of the filtered air flow, the bag type dust collector can be divided into an external filtering type dust collector and an internal filtering type dust collector. When the external filter type bag type dust collector filters, the filtered air flow passes through the filter material from the outer side of the filter bag to flow into the filter bag, and dust particles are attached to the outer surface of the filter bag; when the inner filter type bag type dust collector filters, the filtered air flow passes through the filter material from the inner side of the filter bag to the outer side of the filter bag, and dust particles are attached to the inner surface of the filter bag. After a period of operation, the dust layer accumulated on the dust facing surface of the filter bag of the bag type dust collector is thicker and thicker, so that the resistance loss of the dust collector is increased. Therefore, the bag house needs to be cleaned after a certain period of operation. The ash removal mode of the existing bag type dust remover mainly adopts pulse ash removal. The pulse blowing ash removing mode is to blow high pressure air into the filter bag at high speed for a short time (usually not more than 0.2 seconds) to generate reverse blowing air flow opposite to the filtering air flow, so that pulse expansion shaking is generated in the filter bag, the wall of the filter bag obtains high outward acceleration, and dust is shaken off.

The Chinese patent publication No. CN1857763A discloses a bag pulse back-blowing dust removing device, which solves the problems: according to the material, gas characteristic and temperature etc. factors of sack, current sack dust collector diameter is 3.5 meters generally, and dust removal sack length is 6 meters and diameter 130 millimeters generally, sets up 192 dust removal sack in the case, because sack pulse blowback system's blowback efficiency restriction, the effective length of sack can not increase, and the dust removal box quantity of whole dust removal system is more, and area is big, and the cost is higher. Said invention utilizes a large quantity of dust-removing cloth bags and increases effective length of said cloth bags, and utilizes two-stage back-blowing system to respectively make back-blowing at inlet and middle portion of said dust-removing cloth bags so as to raise dust-removing area of said dust-removing cloth bags and raise dust-removing effect.

However, in some small dust-removing devices, such as dust-removing cabinets with the size of a vertical refrigerator, dust-removing bags are made into a thicker cylinder, the height and width of the dust-removing bags are less than 1 meter, the number of the dust-removing bags is four or five, and compared with 192 dust-removing bags which are 6 meters long and can be arranged in dust-removing devices with the diameter of 3.5 meters, the two-stage back-blowing system is not applicable to the short and thick dust-removing bags.
