Abstract
The utility model discloses a filter bag dust collector of a lower air inlet sub-chamber structure. The filter bag dust collector comprises an ash hopper, a box body, a plurality of filter bags, an air inlet, an air outlet, an air inlet duct and an air outlet duct, wherein the ash hopper is located below the box body; the air outlet is formed in the top of the box body; the plurality of filter bags are arranged in the box body; the air inlet duct is a space inside the box body from the air inlet to the outside of the filter bags; the air outlet duct is a space inside the box body from the inside of the filter bags to the air outlet; the air inlet duct and the air outlet duct are separated by the filter bags; and the air inlet is formed in the ash hopper, and concretely, the air inlet is formed in the upper part at the side surface of the ash hopper. The pulse jet mode of the dust collector belongs to the powerful low-pressure ash removal mode. When a pulse air flow jets, instant high-pressure air sucks the surrounding secondary air flow five times higher than the instant high-pressure air due to the induction of a venturi tube, and the secondary air flow enters the filter bags. The generated pressure acts on the filter bags, the loading speed is very high, the pressure is quickly transmitted from bag mouths to the bottom end of the filter bags to cause stretching, compression and shearing of bag walls and dust layers, so that the dust layers are broken and fall off and the ash removal effect is obvious.
Description
Technical field
The technical program belongs to the deduster technical field, specifically a kind of bag dust collector of lower air inlet chamber structure.
Background technology
In prior art, bag filter is the dust collection device that is in daily use.Existing bag filter generally comprises ash bucket, casing, filter bag, air inlet duct and exhaust passage, and ash bucket is positioned at below casing, the side opening air inlet of lower box, and the air port is left at the top of casing, and filter bag is in casing.Air inlet duct is space in the casing of air inlet to filter bag, the exhaust passage be in filter bag to the casing of air outlet the space, air inlet duct and exhaust passage are isolated by filter bag.Its operation principle is, flue gas from air inlet duct through filter bag to the exhaust passage, then discharge atmosphere, the dust in filter bag outer wall filtering flue gas, then dust falls into ash bucket.The problem of this structure is, flue gas directly blows on filter bag, and the dust that especially particle is larger is larger to the filter bag impulsive force, can damage filter bag, and simultaneously, all dust all are accumulated on the filter bag outer wall, easily cause the obstruction of filter opening on filter bag.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of bag dust collector of lower air inlet chamber structure, comprise ash bucket, casing, filter bag, air inlet, air outlet, air inlet duct and exhaust passage, ash bucket is positioned at below casing, the air port is left at the top of casing, filter bag is in casing, and filter bag has a plurality of; Air inlet duct is space in the casing of air inlet to filter bag, the exhaust passage be in filter bag to the casing of air outlet the space, air inlet duct and exhaust passage are isolated by filter bag; Described air inlet is opened on ash bucket.Specifically, the position of described air inlet is on the top of ash bucket side.
Also comprise pulse spraying equipment, this device comprises compressed air gas source, injection tube, air valve and nozzle; One end of described injection tube connects compressed air gas source through air valve, other end sealing; The quantity of described nozzle is consistent with the quantity of filter bag, and nozzle is connected on injection tube; Each nozzle is towards the openend of a filter bag.
Described ash bucket below is connected with ash-discharging device.
Described nozzle is Venturi tube.
This deduster adopts lower air inlet chamber structure, and ash-laden gas enters ash bucket by air inlet; The larger grit of part is because the effects such as inertial collision, natural subsidence directly fall into ash bucket, and other grit enters each bag chamber with the air-flow rising.After filter bag filtered, grit was delayed at the filter bag outside, and purified gas enters the exhaust passage by filter bag inside, enters atmosphere through air outlet.Dust in ash bucket regularly or is continuously drawn off by ash-discharging devices such as reaching rigidity impeller discharger or flap valve.
The pulse jet of this deduster belongs to the powerful deashing of low pressure.When air pulse sprayed, the instantaneous pressure air poured filter bag higher than secondary gas flow of five times itself due to the Venturi tube inducing action around aspirating.The pressure that produces is made the used time loading velocity to filter bag and is exceedingly fast, and is transmitted to bag bottom news speed by sack, cause bag wall and dust layer stretching, compression, shear, make that dust layer breaks, comes off, ash-removal effect is obvious.

Fig. 2 is the structural representation of nozzle;
In figure, ash bucket 1, casing 2, filter bag 3, air inlet 4, air outlet 5, injection tube 6, nozzle 7, ash-discharging device 8, the arrow direction is air direct.
The specific embodiment
The technical program is further illustrated as follows below in conjunction with accompanying drawing and the specific embodiment:
A kind of bag dust collector of lower air inlet chamber structure comprises ash bucket, casing, filter bag, air inlet, air outlet, air inlet duct and exhaust passage, and ash bucket is positioned at below casing, and the air port is left at the top of casing, and filter bag is in casing, and filter bag has a plurality of; Air inlet duct is space in the casing of air inlet to filter bag, the exhaust passage be in filter bag to the casing of air outlet the space, air inlet duct and exhaust passage are isolated by filter bag, described air inlet is opened on ash bucket.Specifically, the position of described air inlet is on the top of ash bucket side.
Also comprise pulse spraying equipment, this device comprises compressed air gas source, injection tube, air valve and nozzle; One end of described injection tube connects compressed air gas source through air valve, other end sealing; The quantity of described nozzle is consistent with the quantity of filter bag, and nozzle is connected on injection tube; Each nozzle is towards the openend of a filter bag.
Described ash bucket below is connected with ash-discharging device.
Described nozzle is Venturi tube.
