Description
Technical field
The utility model relates to a kind of deduster, particularly relates to pulse filter bag type deduster.
Background technology
Pulse bag type dust collector is since the fifties comes out, through widely using both at home and abroad, update, achieve in purification dusty gas and develop on a large scale very much, because ash-clearing technology is advanced, air cloth ratio increases substantially, therefore has the features such as process air quantity is large, floor space is little, purification efficiency is high, reliable operation, structure simple, a little repair.Efficiency of dust collection can reach more than 99%.A kind of fairly perfect high-effective dust-removing equipment of maturation.Pulse bag type dust collector is widely used in food, pharmacy, feed, metallurgy, building materials, cement, machinery, chemical industry, electric power, the purification of dusty gas of light industry and the recovery of particulate dust.But usually there is following shortcoming in pulse bag type dust collector: resistance is slightly high; When cloth bag is many, judge broken bag position time length etc.
Summary of the invention
The purpose of this utility model is to provide pulse filter bag type deduster, solve above-mentioned in use can gas-flow resistance large, judge that the broken bag position time is long and be not easy to the problem of plant maintenance.
The utility model is achieved like this: pulse filter bag type deduster, comprises upper box, middle casing and lower box, it is characterized in that upper box, middle casing and lower box are combined; Several filter bags are equipped with in described upper box bottom, and filter bag is platform vertebra shape, and to reduce gas-flow resistance, be provided with barometer in each filter bag, middle part is provided with high pressure gas bag, impulse electromagnetic valve and tracheae, and the cover plate on top is detachable, and right side is provided with air outlet; Described middle casing front is provided with access door, and left side is provided with air inlet; Described lower box is provided with support, and below ash bucket box, is provided with unloading valve bottom ash bucket box, and top is provided with spiral ash-pushing machine.
Described impulse electromagnetic valve is by pulse-triggered instrument control system, and the gases at high pressure that the cycle abrupt release set according to pulse-triggered instrument from different tracheaes replaced is released from high pressure gas bag are to filter bag.
Described barometer is connected to pressure display table, can check all barometrical air pressure by pressure display table.
The principle of pulse dust collector is: at dusty gas from deduster air inlet enters, lower box enter in the process of upper box by filter bag, thicker particle and most of dust, under the effect of primary settling and deadweight, fall into ash bucket and are discharged from ash hole by dust through auger conveyor.Another part is fine dust comparatively, due to the various effect effects of filter bag, is attracted on filter bag, after entering upper box, is discharged by air outlet through the Purge gas of filter bag.Along with the increase of working time, the dust be adsorbed on filter bag gets more and more, and the resistance of filter bag to air-flow also increases thereupon, causes and is reduced gradually by the gas flow of filter bag.For making the draught control of filter bag in the scope that deduster can normally work, just must carry out periodicity to the dust that filter bag adsorbs to remove, dust out is by pulse control instrument clocked flip low-pressure pulse valve, cylinder closes gas chamber ventilation mouth, gas bag compressed air sprays through air valve instantaneously, filter bag is sharply expanded, with after-contraction, the dust being adsorbed on cloth bag surface is all fallen, send through ash bucket and conveying mechanism, effectively reduce the running resistance of equipment, the system of guarantee is in the duty of normal table simultaneously.
The beneficial effects of the utility model are pulse filter bag type dedusters of the present utility model, in use can reduce gas-flow resistance, detect filter bag air pressure in real time and are convenient to plant maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings, 1, upper box 2, middle casing 3, lower box 4, filter bag 5, pulse-triggered instrument 6, gas bag 7, impulse electromagnetic valve 8, upper cover plate 9, tracheae A 10, tracheae B 11, barometer 12, air pressure display list 13, air inlet 14, air outlet 15, access door 16, support 17, spiral ash-pushing machine 18, unloading valve.
Detailed description of the invention
As shown in Figure 1, pulse filter bag type deduster of the present utility model, comprises upper box (1), middle casing (2) and lower box (3), it is characterized in that upper box (1), middle casing (2) and lower box (3) are combined; Several filter bags (4) are equipped with in described upper box (1) bottom, filter bag (4) is platform vertebra shape, be set to platform vertebra shape and can increase filtering surface, reduce gas-flow resistance, be provided with barometer (11) in each filter bag (4), middle part is provided with high pressure gas bag (6), impulse electromagnetic valve (7), tracheae A(9) and tracheae B(10), the upper cover plate (8) on top is detachable, easy access, right side is provided with air outlet (14); Described middle casing (2) front is provided with access door (15), easy access, and left side is provided with air inlet (13); Described lower box (3) is provided with support (16), below ash bucket box, is provided with unloading valve (18) bottom ash bucket box, and top is provided with spiral ash-pushing machine (17), dust can be pushed to unloading valve (18) top.
Described impulse electromagnetic valve (7) is controlled by pulse-triggered instrument (5), alternately from tracheae A(9) and tracheae B(10) the cycle abrupt release that sets according to pulse-triggered instrument (5) gases at high pressure of releasing from high pressure gas bag (6) are to filter bag (4), because gas bag (6) can not simultaneously to all filter bags (4) output high-pressure gas, and gases at high pressure are abrupt release, so little to normal dedusting work influence.
Described barometer (11) is connected to pressure display table (12), can pass through the air pressure that pressure display table (12) checks all barometers (11); The air pressure on corresponding pressure display table (12) can be observed in the moment of gases at high pressure release, for the filter bag (4) corresponding to the pressure gauge (11) that pressure change is obviously abnormal, just can judge whether broken bag.
