Embodiment 1

[0025] like figure 1 and 2 As shown, a new type of pulse filter type dust removal tank involved in this embodiment includes a tank body 1; the bottom of the tank body 1 is a cone-shaped structure, and the top is an oval structure; the top of the tank body 1 is provided with a safety valve 19 and a pressure gauge 20. A discharge port 21 and an air inlet 22 are provided on the bottom side of the tank body 1; an inspection manhole 23 is respectively provided on the top, side and bottom of the tank body.

[0026] The inside of the tank body 1 is sequentially provided with a dust removal filter cartridge 2 and a dust removal cloth bag 3 from top to bottom; the bottom of the dust removal cloth bag 3 is fixed on the inner wall of the tank by a fixing frame 12 ; the top of the dust removal filter cartridge 2 is provided with a porous plate 13 and the secondary pulse backflushing assembly 14; the top of the dust bag 3 is provided with a primary pulse backflushing component 24; above t...

Embodiment 2

[0035] like image 3 and 4 As shown, the structure of a new type of pulse filter type dust removal tank involved in this embodiment is basically the same as that of Embodiment 1, and the difference lies in:

[0036] The partition plate 5 extends downward to the bottom of the tank body 1, and is sealed with the bottom of the tank body 1. The dust collecting chamber 6 is divided into an upper dust collecting chamber 601 and a lower dust collecting chamber 602 by the inclined metal baffle 25; A spare hole 31 is provided on the side of the lower dust collection chamber 602; the high-end side of the baffle 25 is hinged with the baffle 5, and the hinge can be sealed to prevent gas from overflowing; the bottom of the baffle 25 and the baffle 5 are connected by a spring-26 Support, the spring one 26 is always in a compressed state, and the baffle plate 25 is pressed upward, so that the lower end side of the baffle plate 25 is in close contact with the inner wall of the tank 1; the ba...

Abstract

The invention relates to the technical field of dust removal equipment, in particular to a novel pulse filter element type dust removal tank which comprises a tank body. A dust removal filter drum and a dust removal cloth bag are arranged in the tank body; a plurality of dust removal cloth bags are arranged below the dust removal filter cartridge; the top heights of the dust collecting bags are gradually reduced from the inner wall of the tank body to the partition plate; a dust collection cavity is formed between the partition plate and the inner wall of the tank body; dust collecting plates are arranged above the dust collecting cloth bags; the dust collecting plate is obliquely arranged and is matched with the tops of the plurality of dust collecting bags; a dust inlet pipe is arranged below the dust collecting cloth bag and connected with a separation cover, and an opening of the separation cover faces downwards. The technical scheme of combining primary cloth bag dust removal and secondary filter cartridge dust removal is adopted, so that the dust concentration gradient can be formed, and the same dust removal device can meet the requirements of different dust removal emission concentrations.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a novel pulse filter type dust removal tank. Background technique [0002] Processing enterprises will generate a lot of dust in the process of processing and production. If the dust is directly discharged, it will cause damage to the environment and endanger human health. Therefore, it is necessary to filter the dust in the air. The existing technology usually uses filter cartridges or filter bags to filter dust. For example, Chinese patent CN204768047U discloses a filter cartridge dust collector in the field of dust removal devices. The wall is provided with an air outlet, and the dust removal box is provided with a partition plate. The interior of the dust removal box is located above and below the partition plate to form a clean air chamber and a dust filter chamber. The dust filter chamber is vertically provided with a filter cartridge. The upper opening of t...
