Gliding blowing bag-type dust remover for large-sized cement kiln

Abstract

The invention provides a sliding injection bag type dust remover which is used for a large-scale cement kiln. The sliding injection bag type dust remover includes upper box bodies, middle box bodies, a dust hopper, filter bags and injection tubes, the upper box body is communicated with the middle box body, the middle box body is divided into a plurality of filter chambers, a plurality of filter bags are suspended in the filter chambers, the dust hopper is arranged below the filter chambers; the interior of the upper box body is provided with a plurality of injection tubes which are corresponding to each filter bag, the two adjacent filter chambers are in one group, the air inlet ends of the injection tubes are extended between the two filter chambers, gate valves are arranged on the pipe ends of the air inlet ends of the injection tubes; a sliding injection device which is composed of a sliding small car, a sliding track, a motor, a screw rod, a pulse valve and an air bag is arranged between the upper box bodies of each group of the filter chambers, the small car is arranged on the sliding track, the screw rod is respectively connected with the motor and the sliding small car, and the pulse valve is connected with the air bag. The sliding injection bag type dust remover can effectively reduce the number of the pulse valves, reduce the production cost of the dust remover, facilitate the detection and the maintenance and improve the working efficiency and the dust removing effect.

Description

technical field [0001] The invention relates to flue gas purification technology, in particular to a sliding blowing bag type dust collector for large cement kilns. Background technique [0002] At present, the bag filter used for large cement kiln is mainly composed of upper box, middle box, ash hopper, filter bag and injection device. The upper box is connected with the middle box through the flower plate, and the middle box The body is divided into several filter chambers, and several filter bags are suspended in each filter chamber, and an ash hopper is arranged under each filter chamber; several sets of blowing devices composed of pulse valves, air bags and blowing pipes are arranged in the upper box In the body, the blowing pipe is connected to the pulse valve through the air bag, and several blowing ports corresponding to each row of filter bags are opened on the blowing pipe. When cleaning dust, through the action of the pulse valve, high-speed compressed air is rel...

AI Technical Summary

Problems solved by technology

In order to improve work efficiency, the existing bag filter used in large cement kilns has a large volume due to the large amount of gas to be processed, and contains several filter chambers and thousands of filter bags, which requires hundreds of sets of blowing devices , the pulse valve in the injection device is more expensive, which greatly increases the cost of the bag filter, especially when one of the pulse valves fails, it is very difficult to detect and maintain, which seriously affects production and reduces work efficiency
