High-temperature bag type pulsed dust collector

Abstract

The invention relates to a bag type pulsed dust collector capable of treating high-temperature flue gas and other high-temperature dust. The bag type dust pulsed dust collector comprises an upper blowing system, an upper box body, a middle box body which is formed by circling four side plates and a top pattern plate, and a plurality of lower dust hoppers, wherein a door cover is arranged on the top of the upper box body; the upper blowing system and a pneumatic lift valve are arranged on the upper box body; an air channel is arranged on one side in the middle box body; a spacer plate which divides the air channel into an upper air chamber and a lower air chamber is arranged in the air channel; the upper air chamber of the air channel is communicated with the upper box body, and the lower air chamber of the air channel is communicated with the lower dust hoppers; a dust-contained gas air inlet is formed on each lower dust hopper on one side of the air channel; a purified gas air outlet corresponding to the air inlet is formed on a middle box body side plate of the upper air chamber; and a cold air inlet is formed at one end of the lower air chamber. Because the cold air inlet is formed at one end of the lower air chamber, once the dust collector encounters an ultra-temperature alarm, the valve can be automatically opened quickly, and then cold air is directly supplemented to effectively protect a filter bag of the dust collector.

Description

technical field [0001] The invention relates to a bag-type pulse dust collector, in particular to a bag-type pulse dust collector capable of processing high-temperature flue gas and other high-temperature dust. Background technique [0002] Bag-type pulse dust collectors are mainly used in metallurgy, building materials, electric power, chemical and other enterprises, and most of them use long-bag pulse bag dust collectors. The dust collector mainly includes an upper pulse injection system, an upper box, a middle box surrounded by four side panels and a top flower plate, and one or more lower ash buckets. The top of the upper box is provided with a door cover. The upper pulse injection system and pneumatic poppet valve are installed on the body, and the air duct vertical partition is arranged on one side of the middle box body, and the air duct vertical partition forms an air duct with the side plate on one side of the middle box body, and the two ends of the air duct are re...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the bag-type pulse dust collector has an air inlet and an air outlet, and the air inlet and the air outlet are arranged on the middle box. This structure will cause the dust-laden gas to enter the dust collector unevenly; secondly, this The dust collector with this structure is difficult to adapt to the dust removal of high-temperature gas. The temperature of high-temperature gas dust removal is very high, and it is difficult to go to the top and side of the dust collector for maintenance and inspection. If the blowing system on the top of the dust collector fails, it will affect the normal production of the enterprise. , the enterprise will suffer huge losses
