Blowing device with large air rate in a movable and positioning way

Abstract

The invention belongs to the technical field of environment-friendly equipment, and relates to a pulse dust cleaning device of a fixed pulse bag type dust remover and dust removing equipment using the pulse dust cleaning device. The pulse dust cleaning device is a pulse blowing device matched with the bag type dust remover. The pulse blowing device comprises a blowing device body; a large air storage bag is connected with a blowing branch pipe in the body through an intake-tube; and a pattern plate arranged at the bottom of the body is provided with a plurality of filter bag holes; and the pulse blowing device is characterized in that the blowing branch pipe can be positioned and moved on the pattern plate arranged at the bottom of the body. According to the invention, after the structure of the device and the dust cleaning method are adopted, the blowing in a movable and positioning way can be realized, the quantity of the blowing pipes and the pulse valves can be reduced, the cost of investment is low, the overhaul rate is low; and the pulse blowing device is large in air rate for dust cleaning, thereby being easy to clean surface dust on the filter bag.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and relates to a pulse bag type dust removal device, in particular to a pulse dust removal device of a fixed pulse bag type dust collector and a dust removal device using the device. Background technique [0002] Disclosed a kind of line injection device of dust catcher on the market at present, is made up of small-sized electromagnetic pulse valve (3 ~ 4 inches), distribution box, wall plate connector, injection pipe, Venturi tube etc. The electromagnetic pulse valve is controlled by the output signal of the pulse injection controller, and the air is supplied by the compressed air pipe network or an independent air compressor. The pulse injection device with this structure has a small air injection volume and cannot achieve the ideal dust removal effect, especially for longer filter bags, which is not easy to clean dust, thus increasing the operating burden of the puls...

AI Technical Summary

Problems solved by technology

The pulse injection device with this structure has a small air injection volume and cannot achieve the ideal dust removal effect, especially for longer filter bags, which is not easy to clean dust, thus increasing the operating burden of the pulse bag filter and increasing energy consumption; Medium pressure or high pressure dust removal methods are likely to cause damage to the filter bag and serious wear of the injection pipe; the pulse valve of this type of injection device is located on the side of the air bag, which is extremely inconvenient for maintenance; and because the small electromagnetic pulse valve can spray the filter The number of bags is limited, resulting in a large number of pulse valves used in the entire dust collector, generally dozens to hundreds, cumbersome operation and management, bulky dust collector equipment, high steel consumption, and large investment

[0003] The other is a rotary blowing device with a top air storage tank. The compressed air is stored in a special air bag. Each rotary blowing unit is equipped with an independent air bag and a set of motor equipment, which are installed on the top of the dust collector. Above, there is a temperature difference between the compressed air and the flue gas, which will cause condensation and nozzle corrosion; if the capacity of the unit is large, the matching air bag needs to be increased, and the wind load strength design also needs to be increased, and the air bag is placed on the top of the dust collector. The top shakes violently, forming a phenomenon of top-to-bottom, which will affect the transmission mechanism and so on.
