Description

Dust filter

Technical Field

The utility model belongs to the technical field of energy-saving and environment-friendly equipment, and particularly relates to a dust filter.

Background

The flue gas of an incineration treatment plant contains a large amount of smoke dust, and before the flue gas is subjected to environment-friendly treatment, dust removal equipment is required to be used for carrying out dust removal treatment on the flue gas. The current processing mode is to only use one set of dust collecting equipment to remove dust to the flue gas, can influence on the one hand and remove dust and strain, and on the other hand can reduce dust collecting equipment's life. If the pre-dedusting is carried out before the dedusting equipment is used for dedusting the flue gas, the service life of the subsequent dedusting filter and the dedusting equipment can be prolonged. Therefore, it is necessary to design a pre-dedusting dust filter before dedusting of the dedusting equipment.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a pre-dedusting dust filter used before dedusting of dedusting equipment, which can pre-remove dust from flue gas, filter out partial dust in the flue gas, and then convey the part of the dust to dedusting filtering equipment for dedusting, so that the dedusting efficiency is improved, and the service life of the dedusting equipment is prolonged. The filter has the advantages of simple structure, low manufacturing cost, economy and practicality, and is easy to popularize and use on a large scale.

The technical scheme adopted by the utility model is as follows: a dust filter comprising a filter box and a dust hopper; the filter box comprises a box body, a box cover and a plurality of filter plates, wherein inclined slots are uniformly distributed in the bottom of the box body, an air inlet pipe and an air outlet pipe are respectively arranged at two ends of the box body, each filter plate comprises a square frame and dust removing cloth, the dust removing cloth is fixed on the square frame through uniformly distributed rivets, and the filter plates are inserted into the inclined slots; the box body is divided into a plurality of chambers by the plurality of filter plates, a round hole is formed in the bottom of the box body at the bottom of each chamber, a funnel is welded below the round hole, a pipeline is welded at the bottom of the funnel, a valve is installed on the pipeline, the bottom of the pipeline is welded at the top of the dust hopper, and a dust removal port is formed in the bottom of the dust hopper; the box cover is installed on the outer edge of the box body through bolts.

Furthermore, a rubber strip is arranged between the outer edges of the box cover and the box body.

Furthermore, gaps between the periphery of the filter plate and the box cover and between the periphery of the filter plate and the box body are not larger than 1 millimeter.

Further, the number of the filter plates is not less than four.

The utility model has the beneficial effects that: the utility model provides a dust filter removes dust in advance for dust collecting equipment removes dust before, this dust filter can remove dust in advance to the flue gas, filters out the partial dust in the flue gas earlier after, carries to dust removal filtration equipment again and removes dust, and then improves dust collection efficiency and dust collecting equipment's life. The filter has the advantages of simple structure, low manufacturing cost, economy and practicality, and is easy to popularize and use on a large scale.

Detailed Description

Example one

Referring to the figures, a dust filter comprises a filter box 1 and a dust hopper 5; the filter box 1 comprises a box body 11, a box cover 12 and a plurality of filter plates 13, wherein the bottom of the box body 11 is provided with uniformly distributed inclined slots 15, two ends of the box body 11 are respectively provided with an air inlet pipe 17 and an air outlet pipe 14, the filter plates 13 comprise square frames 18 and dust removing cloth 19, the dust removing cloth 19 is fixed on the square frames 18 through uniformly distributed rivets 20, and the filter plates 13 are inserted in the inclined slots 15; the box body 11 is divided into a plurality of chambers by the plurality of filter plates 13, a round hole 16 is formed in the bottom of each chamber, a funnel 2 is welded below the round hole 16, a pipeline 3 is welded at the bottom of the funnel 2, a valve 4 is installed on the pipeline 3, the bottom of the pipeline 3 is welded at the top of the dust hopper 5, and a dust removal port 6 is formed in the bottom of the dust hopper 5; the box cover 12 is mounted on the outer edge of the box body 11 through bolts; a rubber strip is arranged between the outer edges of the box cover 12 and the box body 11; the gap between the periphery of the filter plate 13 and the box cover 12 and the box body 11 is not more than 1 mm.

Taking the smoke dust in the smoke gas of a filtering and burning treatment plant as an example, the burning smoke gas enters the filter box through the air inlet pipe, the smoke gas firstly filters the smoke dust through the inclined dust removing cloth in the first cavity, and the filtered smoke dust falls into the funnel of the cavity. The flue gas enters a second cavity after being subjected to primary dust removal, the flue gas is continuously filtered and dedusted by the dedusting cloth of the second cavity, and by analogy, the flue gas is subjected to multiple times of filtering and dedusting by a plurality of dedusting cloths and then is discharged by the air outlet pipe to enter subsequent dedusting and filtering equipment for next dedusting. And closing the valve on the funnel pipeline in the early stage of flue gas dust removal, so that a certain amount of smoke dust is deposited at the bottom of each dust removal chamber. Then the valves at the bottom of each hopper are opened one by one, the smoke dust in the hoppers slowly falls into the dust collecting hopper by adjusting the valves, and the valve opening amount of the first chamber through which the smoke gas firstly passes is usually larger. The dust removal port at the bottom of the dust collection hopper is communicated with the inlet of the screw conveyor, and the filtered smoke dust is conveyed to the collecting device through the screw conveyor.
