Pulse cloth bag dust remover capable of easily collecting ash

Abstract

The invention discloses a pulse cloth bag dust remover capable of easily collecting ash. The pulse cloth bag dust remover comprises a box body and an ash outlet pipe, wherein a ceiling and a cage framework are fixedly connected in the box body; a plurality of filter bags are fixedly connected between the ceiling and the cage framework; beating blades are connected between the ceiling and the cage framework and at two sides of the filter bags in a rotary manner; upper ends of the filter bags are connected with a venturi tube penetrating through the ceiling; a blowing pipe is further fixedly connected with a position, located above the ceiling, in the box body; the lower part of the box body is connected with a brushing shaft in the rotary manner; the brushing shaft is fixedly connected with a plurality of brushing plates; an opening formed in the lower end of the box body is communicated with the upper end of the ash outlet pipe; the ash outlet pipe is fixedly connected below the box body; the ash outlet pipe is internally connected with a spiral blade in the rotary manner; an atomizer is further fixedly connected with the lower end of the ash outlet pipe; an outlet of the atomizer is communicated with a flow spitting box; the lower end of the flow spitting box is communicated with a plurality of humidifying nozzles introduced into the ash outlet pipe. The pulse cloth bag dust remover capable of easily collecting the ash is high in reverse blowing and ash falling efficiency, dust is not stuck and remained and does not cause secondary pollution after being discharged; energy saving and high efficiency are realized.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a pulse bag dust collector which is easy to collect dust. Background technique [0002] The pulse bag filter is a new type of high-efficiency pulse bag filter improved on the basis of the bag filter. In order to further improve the pulse bag filter, the improved pulse bag filter retains the advantages of high purification efficiency, large gas handling capacity, stable performance, convenient operation, long filter bag life, and small maintenance workload. And the pulse valve was reformed to solve the problem of open air placement and low pressure of compressed air source. The specific working principle is that the dusty gas enters the ash hopper from the air inlet channel, and the coarse dust particles directly fall into the ash outlet at the bottom of the box, and the fine dust particles fall directly into the ash outlet at the bottom of the box. The dust particles turn upwards with th...

In order to further improve the pulse bag filter, the improved pulse bag filter retains the advantages of high purification efficiency, large gas handling capacity, stable performance, convenient operation, long filter bag life, and small maintenance workload. And the pulse valve is reformed to solve the problem of open air placement and low pressure of compressed air source. Dust particles turn upwards with the airflow and accumulate on the outer surface of the filter bag. The filtered gas enters the upper part of the box and is discharged to the atmosphere. The process of cleaning dust is to cut off the outlet air duct first, so that the filter bag in the room is in a state of no air flow. Then open the pulse valve and use compressed air to carry out pulse jet soot cleaning. The closing time of the cut-off valve is enough to ensure that the dust stripped from the filter bag after blowing settles to the ash hopper, preventing the dust from being attached to the airflow after leaving the surface of the filter bag. The surface of the adjacent filter bag makes the filter bag clean thoroughly, and the exhaust valve, pulse valve and ash discharge valve are fully automatically controlled by the programmable controller. It can be seen that the cleaning process mainly depends on the filter bag. It is realized by the deformation and internal high-pressure wind blowing. In order to ensure thorough dust removal, the pulse valve needs to be opened for a long time, which takes a lot of time and high-pressure gas, which means that the energy consumption is increased in disguise (the power of the air compressor is very high. Large), in addition, in addition to the filter bag, the ash hopper at the lower part of the box is also very easy to accumulate dust, especially when the exhaust gas contains a certain humidity, a large amount of dust accumulates and condenses in the ash hopper, which has a great impact on subsequent cleaning Most of the existing pulse bag filter ash discharge is directly discharged into the ash collecting hopper, and these fine ash are easily scattered with the wind, causing secondary pollution
