Description

Technical Field

[0001] The utility model relates to the field of dust removal, in particular to a dual-purpose dust collector. Background Art

[0002] Dust-laden flue gas enters the dust collector from the inlet, and is then evenly distributed to each dust removal chamber through air flow distribution, passing through the filter cartridge at a wind speed of about 0.7m / min. The dust is isolated on the outside of the filter cartridge by the filter cartridge, and the clean flue gas passes through the pores of the filter cartridge and enters the inside of the filter cartridge, and then is collected in the clean air chamber, and finally discharged from the outlet. The dust attached to the surface of the filter cartridge forms a dust layer after a period of time. When the resistance of the dust layer reaches about 600Pa, the compressed air backflush system is started, and compressed air is sprayed into the inside of the filter cartridge, so that the external dust falls from the outside of the filter cartridge into the ash hopper, and then sent to the ash storage bin through the ash conveying system.

[0003] The prior art has the following problems:

[0004] With the improvement of filter cartridge technology, room temperature filter bags can gradually be replaced by filter cartridges. Traditional flower plates can only be adapted to filter bags. When adapting to filter cartridges, the flower plates need to be modified. There is a lack of new flower plate structures that can allow dust collectors that originally used conventional filter bags to use filter cartridges. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] like Figure 1-3 As shown, a dual-purpose dust collector proposed by the utility model comprises a dust collector 1, wherein the dust collector 1 has a built-in partition 11 for separating a dust removal chamber and a clean air chamber, an ash hopper 4 is installed at the lower part of the dust removal chamber, and a through air inlet terminal 13 is connected to the side wall, and a dust cleaning mechanism is built-in in the clean air chamber, and a through exhaust terminal 14 is connected to the side wall;

[0027] The partition plate 11 is provided with a plurality of through holes, and filter material members 12 are arranged in the through holes;

[0028] The flower plate mechanism includes a flower plate 21, and a pressure ring 22 is arranged at the position corresponding to the through hole of the flower plate 21. The pressure ring 22 is a "U-shaped" structure, and the filter material 12 is clamped therein. A rubber ring sheet 23 is arranged at the lower layer in the gap between the filter material 12 and the filter material 12, and an air bag 24 is arranged at the upper layer. A vent valve 25 penetrating the pressure ring 22 is installed in the air bag 24.

[0029] It should be noted that: a gas passage is established between the dust removal chamber and the clean air chamber through the filter material 12, the dust-containing gas is filtered by the filter material 12, and the filtered crystallized gas enters the inner cavity of the filter material 12 and is transported to the clean air chamber;

[0030] Wherein, the filter material element 12 is a filter cartridge structure;

[0031] Or the filter material element 12 is a filter bag structure;

[0032] Both are also clamped and fixed at the partition plate 11 through the flower plate mechanism.

[0033] In this embodiment, the filter material 12 is first placed in the through hole of the partition 11, and the pressure ring 22 on the flower plate 21 is moved close to the through hole. One end of the pressure ring 22 that penetrates the through hole of the partition 11 is attached to the inner wall of the filter material 12, and the other end of the pressure ring 22 is attached to the outer wall of the filter material 12. The inner and outer walls of the filter material 12 are stretched and clamped inside and outside the through hole of the partition 11 to fit the excess filter cloth on the filter bag and the filter cartridge, which can assist the installation and use of the filter bag and the filter cartridge.

[0034] When sealing, the rubber ring sheet 23 performs a preliminary sealing of the gap between the pressure ring 22 and the filter material 12. Since there is still a gap that affects the sealing, the gas chamber of the airbag component 24 is inflated through the vent valve 25. The airbag component 24 is an elastic component. After the airbag component 24 is inflated, the gap is sealed again to improve the sealing stability.

[0035] As an example of cleaning: the cleaning mechanism includes an air source connecting pipe 31 arranged in the clean air chamber, and a plurality of pulse valve stations 32 are arranged in the air source connecting pipe 31. A pulse valve 33 that passes through the outside of the clean air chamber is installed at the air inlet end of the pulse valve station 32, and the pulse valve 33 is connected to an external air source; the gas from the external air source is input into each pulse valve 33 of the pulse valve station 32 through the air source connecting pipe 31, and the gas is sprayed through the pulse valve 33 to act on the filter material 12, so that the dust attached to the outer wall of the filter material 12 is blown away and falls. Since the ash hopper 4 is an inverted cone structure, three of them are equidistantly arranged along the air inlet direction in the dust removal chamber, and the fallen dust can be evenly collected.

[0036] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
