Problems solved by technology

[0003] (1) There are many supporting equipment for the dust removal system of the existing dust collector, including: air compressor, air storage tank, compressed air pipeline, regulating valve, air bag, solenoid valve, blowing pipe, clean air lift valve, etc., for To meet the long-term stable operation, some components must be imported products, and the overall equipment cost is relatively high;
[0004] (2) Due to the large amount of supporting equipment in the existing dust collector, the installation workload and strength are increased, and the installation requirements are relatively high, and a large amount of equipment and labor are required for installation;
[0005] (3) The control system of the existing dust collector is complex and has high requirements for operators;
[0006] (4) The power consumption of the existing dust collector is large, and the operating cost is relatively high;
[0007] (5) When there is a problem with any of the existing dust collectors, the fault point is not easy to eliminate, and the maintenance is more complicated, which affects normal production

Embodiment 1

[0028] Such as Figure 1-Figure 4 As shown, a non-powered dust cleaning filter bag dust collector according to the embodiment of the present invention includes a cylindrical shell 1 with an open bottom end, and two first partition vertical plates 2 arranged at intervals are passed through the shell. Three spaces are formed by separating, and the tops of the two first partition vertical plates are not connected to the top plate of the casing, and a certain gap is maintained.

[0029] A first orifice plate 3, a second orifice plate 4 and an air duct baffle 5 are arranged from top to bottom between the two first partition vertical plates; A second partition riser 6 in the same direction as the partition riser, and the top of the second partition riser is connected to the top plate of the housing.

[0030] The inner space of the housing is separated by a first partition riser, a second partition riser, a first orifice plate, a second orifice plate, and an air duct baffle to form ...

Embodiment 2

[0040] The difference between this embodiment and Embodiment 1 is that it also includes a controller, which is electrically connected to each purge valve and dust removal valve; a resistance sensor is arranged at the dust gas inlet, and the resistance sensor Electrically connected with the controller. The purpose of adding a controller is to realize the purpose of automatic dust removal and cleaning of filter bag dust.

[0041] The working process of this embodiment is as follows: firstly, the dust-laden gas is purified, so that all the purification valves open the cleaning plug holes, and all the soot cleaning valves close the soot cleaning plug holes. The dusty gas enters the dust gas channel from the dust gas inlet, and under the action of the air duct baffle, the flue gas will enter down into the funnel ash hopper along the air duct baffle. The larger particles in the flue gas will fall to the bottom of the funnel ash hopper under the action of inertia and gravity. Becau...

Embodiment 3

[0045] The difference between this embodiment and embodiment 1 or embodiment 2 is that: the air duct partition is arranged obliquely downward from the dust gas inlet. The included angle between the air duct partition and the horizontal position is 30-60 degrees. This embodiment adopts an inclined air duct partition, which can make it easier for the dusty gas to enter the dust gas channel from the dust gas inlet. Under the action of the air duct baffle, the flue gas will flow along the air duct baffle Go down into the funnel ash hopper.

[0046] The dust remover of the present invention is divided into various air chambers and passages in the cylindrical shell, and the intersecting plug holes are closed and opened through the air cleaning valve and the dust cleaning valve, so as to achieve the purpose of cleaning air and cleaning dust. The dust collector uses less equipment and objects, which reduces the installation workload and strength of the equipment, and makes the instal...

Abstract

The invention discloses an unpowered ash-removing filtering bag dust remover. The unpowered ash-removing filtering bag dust remover comprises a drum-shaped shell with an opening at the bottom end, wherein the internal space of the shell is partitioned by a first partitioning vertical plate, a second partitioning vertical plate, a first porous plate, a second porous plate and an inclined baffle plate so as to form a first gas chamber, a second gas chamber, an ash-removing gas channel, a gas-purifying channel and a dust-gas channel; the first gas chamber and the second gas chamber are internally and respectively partitioned by a third partitioning vertical plate so as to form a gas purifying chamber and a gas filtering chamber; each gas filtering chamber is internally provided with a plurality of filtering bags; the first porous plate is uniformly provided with a plurality of piston hole groups; the second porous plate is uniformly provided with vent holes, and each piston hole group is respectively and correspondingly provided with a gas purifying valve and an ash removing valve; a plurality of ash hoppers are arranged under the opening in the bottom end of the shell. The unpowered ash-removing filtering bag dust remover disclosed by the invention has the advantages that the purposes of purifying gas and removing ash are achieved by partitioning the internal space of the drum-shaped shell into various gas chambers and channels and using the gas purifying valves and the ash removing valves to close and open piston holes in a crossing manner.
