Description
Technical Field
The invention belongs to the field of dust collectors, and particularly relates to an efficient energy-saving back-blowing bag type dust collector and an ash removal method thereof.
Background
The high dust removal efficiency of the bag filter is not separated from the dust removal mechanism of the bag filter. Dust-containing gas enters the ash bucket through the guide plate by the gas inlet pipeline at the lower part of the dust remover, coarse-grained dust falls into the ash bucket under the actions of collision of the guide plate, reduction of gas speed and the like, and other fine-grained dust enters the filter bag chamber along with the gas. The deposited dust on the filter bag is removed by a gas backwashing method, and the removed dust falls into a dust hopper and is discharged to a dust conveying device through a double-layer dust discharging valve. The dust deposited on the filter bag can also be removed by adopting a method of blowing pulse airflow, thereby achieving the purpose of cleaning the dust, and the removed dust is discharged by a dust discharging device. The high dust removal efficiency of the bag type dust collector is not separated from the filter material, and the performance and the quality of the filter material are directly related to the performance and the service life of the bag type dust collector. The filter material is the main material for making the filter bag, and the performance and quality of the filter material promote the technical progress of bag type dust removal, which influences the application range and the service life of the filter material.
The filtering dust collector includes bag filter and particle layer filter, the former usually uses filter bag made of organic fiber or inorganic fiber fabric as filtering layer, and the latter mainly uses particles with different particle sizes, such as quartz sand, river sand, ceramsite, slag, etc. The powder layer is continuously thickened along with the repeated attachment of the powder to the outer surface of the filter bag, and the resistance value of the bag-type dust collector is increased; the pulse valve diaphragm sends out an instruction, the pulse valve is opened when the left and right sides are submerged, compressed air in the high-pressure air bag is communicated, and if no dust exists or the compressed air is small to a certain degree, the mechanical dust cleaning work can stop working.
The gas purification mode of the low-pressure pulse bag type dust collector is an external filtration type, dust-containing gas enters each unit filtration chamber through a flow guide pipe, sufficient and reasonable airflow is distributed in a proper flow guide and natural flow direction at the vertical distance from the bottom of a filter bag to the upper opening of an air inlet in the design, so that the air distribution in the whole filtration chamber is uniform, particle dust in the dust-containing gas directly falls into a dust hopper after natural sedimentation separation, and other dust enters a middle box body filtration area along with the airflow under the guide of a flow guide system and is adsorbed on the outer surface of the filter bag. The filtered clean gas is discharged through the upper box body and the exhaust pipe through the filter bag.
The filter bag adopts compressed air to perform blowing ash removal, and the ash removal mechanism comprises an air bag, a blowing pipe, an electromagnetic pulse control valve and the like. And the top of the outlet of each row of filter bags in the filter chamber is provided with a blowing pipe, the lower side of the blowing pipe is provided with a blowing port right facing the center of the filter bag, and each blowing pipe is provided with a pulse valve and communicated with a compressed air bag. When in dust cleaning, the pulse valve is opened by the electromagnetic valve, compressed air is sprayed by the dust cleaning control device, the electromagnetic pulse spraying is opened according to a set program under the control of differential pressure or timing and manual control, the compressed air passes through each pulse valve in sequence at a very short time and induces air which is several times of the sprayed air volume by the nozzles on the spraying pipe to enter the filter bag to form air waves, so that the filter bag generates sharp expansion and impact vibration from the bag opening to the bottom, a very strong dust cleaning effect is caused, and dust on the filter bag is shaken off.
In the mode, because all the filter bags are subjected to one-time ash removal, the required air pressure is high, the power of the fan is required to be improved, the fan can only be arranged on the ground, air is introduced into the air compression air bag through the air pipe, the energy consumption is high in the process, an air storage tank and the like are required, and the cost is high. While the discharge part of the ash bucket is common
