Bag-type dust collector

Abstract

The invention discloses a bag-type dust collector. The bag-type dust collector comprises a dust collector box body, wherein the inside of the dust collector box body is divided by a pattern board into an upper gas purifying chamber and a lower smoke chamber, a plurality of filter bags which are communicated with the upper gas purifying chamber are suspended on the pattern board, the bottom of the dust collector box body is provided with an ash bucket which is communicated with the lower smoke chamber, a discharging opening on the bottom of the ash bucket is provided with an ash discharge valve capable of opening or closing the discharging opening, a smoke inlet is formed in a wallboard of an ash head, an air outlet is formed in the side wall of the upper gas purifying chamber of the dust collector box body, an ash stirring hole overhauling door mechanism is arranged on the wallboard of the ash bucket, the ash bucket wallboard in the discharging opening of the ash bucket is provided with a circle of heating board, a plurality of blow pipes are uniformly arranged on the inner wall of the wallboard of the ash bucket at intervals along the circumferential direction, the blow pipes are simultaneously communicated with a high pressure air source, and each blow pipe is provided with a plurality of spray nozzles with spraying openings aligning to the inner wall of the wallboard of the ash bucket along the length direction. The bag-type dust collector has advantages that the application safety is high, and dust is unlikely to cluster in the ash bucket.

Description

technical field [0001] The invention relates to a bag filter. Background technique [0002] In the bag dust removal system, the structure of the bag dust collector currently used is: including the dust collector box, the interior of the dust collector box is divided into an upper clean gas room and a lower flue gas room by a flower plate, and several The filter bag connected with the upper clean air chamber is provided with an ash hopper connected with the lower flue gas chamber at the bottom of the dust collector box, and a discharge port that can open or close the discharge port is provided at the discharge port at the bottom of the ash hopper. The ash valve has a smoke inlet on the wall of the ash head, and an air outlet on the side wall of the dust collector box where the upper clean air chamber is located. A vibrator is installed on the outer wall of the ash hopper. There are maintenance manholes and ash holes respectively on the wall panels, and the maintenance manhol...

AI Technical Summary

Problems solved by technology

The disadvantages of the above-mentioned bag filter are: (1) Due to the frequent use of the vibrator, on the one hand, the ash hopper is easily deformed or even damaged due to vibration, thereby reducing the service life of the ash hopper and increasing the production and use costs of the enterprise; On the other hand, the bolts, supports and other connecting parts used to connect the ash hopper and the dust collector box are prone to loosening, thus burying hidden dangers for production safety; (2) Due to the need for Open the maintenance manhole and the ash hole separately, and then install the inspection door and the ash pipe with the hole cover respectively. The installation is cumbersome, and the ash bucket is also easy to be damaged during the hole opening process, which reduces the service life of the ash bucket; (3 ) after being filtered by the filter bag, the dust falling into the ash hopper is prone to condensation and agglomeration in low temperature environment, which will block the discharge port of the ash hopper, which is not conducive to the smooth discharge of dust from the discharge port of the ash hopper, which greatly reduces the working efficiency
