Description

Technical Field

[0001] The invention relates to the technical field of air treatment, in particular to a V-shaped plate type dust collector. Background Art

[0002] For a long time, the market products of dry dust removal equipment have been relatively single. Only bag dust collectors can handle high dust volumes, but the equipment is bulky and it is difficult to achieve a high filtration accuracy. The filtration accuracy of cartridge dust collectors is appropriately improved, but they also occupy a large area and have low backwash cleaning efficiency. Summary of the invention

[0003] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a V-shaped plate dust collector.

[0004] The present invention is implemented in this way: a V-shaped plate dust collector is constructed, which includes a box body, a bottom plate is fixedly connected to the side wall of the box body, a pulse valve is fixedly connected to the top of the bottom plate, the other end of the pulse valve is connected to the guide pipe, and the guide pipe is arranged in the box body; a partition is provided on the inner wall of the box body, and the partition divides the space in the box body into two groups of spaces on the left and right, the two groups of spaces are specifically spaces for installing filter elements and a transmission channel, and the filter element is slidably inserted into the side wall of the partition body and fixed by bolts.

[0005] Preferably, a reserved opening for explosion-proof disks is provided on the box body, and a box door is movably connected to the side wall of the box body away from the pulse valve; an air inlet is provided on the side wall of the box body, and an air outlet connected to the transmission channel is embedded in the bottom of the box body. The filter element is arranged in a trapezoidal shape, and the longitudinal folds of the filter element are consistent with the direction of airflow, so as to facilitate the pulse gas to blow away dust.

[0006] Preferably, a differential pressure sensor is provided at the outlet of the filter element.

[0007] Preferably, a metal mesh is distributed in the inner cavity of the filter element.

[0008] Preferably, a row of hoppers is fixedly connected to the bottom of the box body, and a top plate is fixedly connected to the top of the filter element.

[0009] Preferably, the top plate is made of metal.

[0010] Preferably, the discharge hopper is connected to the inlet of the auger conveyor.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] Compared with ordinary bag dust collectors, it can accommodate a larger filtering surface area in a smaller area, save installation space, and obtain a large airflow in a smaller volume. The filter element is cleaned in the compressed air pulse, which prolongs the life of the filter element. The cavity structure forms a downward airflow, and the dust falls off the filter element, which is conducive to falling into the ash hopper below.

[0013] The V-shaped plate structure is more in line with the rationality of fluid filtration, and can achieve higher precision in the filtration efficiency of the filter element. At the same time, the plate-type filter element can more easily realize the processing of high-temperature resistant and explosion-proof filter materials.

[0014] Independent airflow design channel avoids re-contamination and interference from falling dust, reduces the duration and frequency of pulse backblowing, and greatly extends the life of the filter element; the structural design is compact, and the equipment occupies the smallest area under the same air volume.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] See also Figures 1 to 7 A V-shaped plate dust collector of the present invention comprises a box body 1, a bottom plate 2 is fixedly connected to the side wall of the box body 1, a pulse valve 3 is fixedly connected to the top of the bottom plate 2, the other end of the pulse valve 3 is connected to the guide pipe 4, the side wall of the guide pipe 4 is provided with a plurality of nozzles, and the guide pipe 4 is arranged in the box body 1; a reserved opening 5 for explosion-proof disk is provided on the box body 1, and a box door 10 is movably connected to the side wall of the box body 1 away from the pulse valve 3; a partition is provided on the inner side wall of the box body 1, and the partition divides the space in the box body 1 into two groups of spaces on the left and right, and the two groups of spaces are specifically spaces for installing filter elements 6 and a transmission channel 11, and the other end of the transmission channel 11 discharges clean air through the air outlet 112, and the filter element 6 is slidably inserted into the side wall of the partition and fixed by bolts, and a row of hoppers 7 are fixedly connected to the bottom of the box body 1.

[0027] During operation, dirty air enters the dust collector through the air inlet 111. A large part of the heavy dust will fall into the ash hopper 6 due to the gravity. Since the dirty air must rotate 90 degrees to enter the filter medium in the filter element 6, the chance of heavy dust falling off is increased. Clean air passes through the filter medium, and the dust in the air is adsorbed and intercepted on the outer surface of the filter element 6. When the dust on the surface of the filter element 6 is collected to a certain extent, the pressure drop of the filter element 6 increases, and the pressure difference sensor arranged behind the filter element 6 will trigger the backflush equipment to work. Cleaning is performed by compressed air pulses. The compressed air enters the pulse valve 3 and is transported to the nozzle on the guide pipe 4 and blown into the filter element 6. The cleaned filter element returns to its clean initial state and continues to serve. The dust in the filter element 6 is blown down by the backblowing system and freely falls into the discharge hopper 7 below. The dust adsorbed on the surface of the filter element 6 is directly pulsed out into the downward airflow in the channel between the filter elements 6 and is directly brought into the discharge hopper 7 by the downward airflow, thus avoiding re-contamination. The filtered air enters the transmission channel 11 and is then transmitted outward through the air outlet 112.

[0028] Specifically, an air inlet 111 is provided on the side wall of the box body 1. When not in use, the air inlet 111 and the air outlet 112 are covered by an external cover. When transported to the working installation area, the cover is opened to connect with the external pipeline. In the initial state, a sealing plate is restricted on the surface of the air inlet 111 by bolts on the side wall of the box body 1. An air outlet 112 connected with the transmission channel 11 is embedded in the bottom of the box body 1, and the air outlet 112 can be connected with an external guide machine.

[0029] Specifically, the inner cavity of the filter element 6 is provided with metal meshes, but there is no metal mesh outside, so that the dust blown back can be released from the outer surface more smoothly.

[0030] Specifically, the inner cavity of the filter element 6 adopts a V-shaped design, and the cross-sectional area decreases along the pulse backblowing direction to increase the speed of the pulse air, so that the cleaning effect of the filter element surface near the nozzle end and far from the nozzle end is equal and does not decay.

[0031] Specifically, the filter element 6 is arranged in a trapezoidal shape, and the longitudinal folds of the filter element 6 are consistent with the direction of the airflow, so that the pulse gas can blow away the dust; there is no external metal mesh, and the dust can rush out of the filter element without any hindrance; a differential pressure sensor is provided at the outlet of the filter element 6; a top plate 8 is fixedly connected to the top of the filter element 6; the top plate 8 is made of metal; it acts as a baffle to distribute the air around the filter.

[0032] Specifically, when multiple groups of V-plate dust collectors are spliced ​​together, the box door 10 is removed to splice the box body 1 together, and the bottom of the discharge hopper 7 at the bottom of the multiple groups of V-plate dust collectors is inserted into the top of the outer shell of the auger conveyor 9, so that the dust falling into the discharge hopper 7 is concentratedly transported to the outside through the auger conveyor 9.

[0033] Specifically, the outer layer of the filter element 6 is provided with a nanofiber layer, which is used to produce a surface load of large particles. The captured surface particles enhance the dust release performance of the filter, thereby improving product performance, and can pulse-deeply load particles to extend the service life and performance of the filter.

The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.
