Abstract
The utility model discloses an ash removing device used for a box-type pulse bag deduster, belonging to the technical field of bag dedusters, and aiming at providing the ash removing device which is used for the box-type pulse bag deduster and can lead to uniform ash removal and same ash removal effect of a filter bag in a bag chamber. The technical points are as follows: tank bodies at two sides of a gas purification chamber (6) arranged above each bag chamber (10) are correspondingly provided with two groups of pulse valves (2A1, 2B1, 2A2, 2B2). The pulse valves are used alternatively and in turn for removing ash at a fixed point in a designated area, thus realizing the uniform ash removal of the filter bags in the same bag chamber, and being capable of reducing pulse ash removal pressure ( reducing to 0.3 to 0.45 MPa), the impact of compressed air on the filter bags, and the discharging concentration at an outlet, and improving the service life and ash removal effect of the filter bags; and the ash removing device can be widely used for controlling dust pollution in the industries of building material, metallurgy, chemical engineering, electricity, and the like.
Description
Technical field
The utility model relates to a kind of deashing device that is used for box pulse packet deduster, belongs to the bag dust collector technical field.
Invention " wide box body combinations pulse dust cleaning technology " belongs to the key technology in the wide casing gas tank formula pulse packet deduster that maximizes, and uses the bag dust collector of this technology can be widely used in the dust pollution of industries such as administering building materials, metallurgy, chemical industry, electric power.
Background technology
Use more bag dust collector at present and mainly contain gas tank formula pulse packet deduster, the turnover wind of this as shown in Figure 1, 2 gas tank formula pulse packet deduster is shared same air channel usually, and the clean gas after dusty gas, turnover air channel and the purification is separated by the air channel dividing plate of an inclination.Dusty gas enters ash bucket 8 by air inlet duct 4, after filter bag 9 filters, enters atmosphere by air-purifying chamber 6, exhaust passage 5, outlet air flange 7.When dust was stacked into certain thickness on filter bag, corresponding two pulse valves that are provided with 2 sprayed compressed air and carry out deashing on the casing of air-purifying chamber 6 both sides by being arranged on 10 tops, bag chamber again.We are by repeatedly theoretical calculating and experimental study show, when the pulse valve deashing, one side of close soot cleaning valve valve is owing to the high speed of pulse jet air-flow is passed through, can produce a negative pressuren zone in this zone, make this zone become the weak link of deashing, actual ash-removal effect is relatively poor, cause the filter bag of same bag chamber interior can not be by even deashing, cause the indoor filter bag of each bag can not keep identical filtration load, bag indoor section filter bag filtration resistance is higher, the lost of life, after the first breakage of local filter bag, indoor other filter bag of bag often needs and then to change in advance.
Summary of the invention
The purpose of this utility model is to provide a kind of can make the indoor deashing device that is used for box pulse packet deduster that filter bag ash removal is even, ash-removal effect is identical of same bag.
Its technical scheme is: a kind of deashing device that is used for box pulse packet deduster is characterized in that: on the casing of the air-purifying chamber both sides of top, each bag chamber, correspondence is provided with two group pulse valves.
Above-mentioned two group pulse valve one after the others are used.
Its beneficial effect is: owing to the pulse valve that is provided with according to the air-purifying chamber both sides above each bag chamber, the area condition of pressure distribution when deashing, when calculating each pulse valve deashing at the indoor pairing best region of bag, one after the other by the paired pulses valve is used, to the appointed area deashing of fixing a point, thereby the filter bag ash removal of both having realized same bag chamber interior is even, has guaranteed that the filtration load of the indoor every filter bag of bag is even, has reduced the running resistance of bag dust collector; Can reduce pulse dust cleaning pressure (being reduced to 0.3-0.45MP) again, alleviate the impact of compressed air, reduce the outlet concentration of emission, improve life of bag filter and ash-removal effect filter bag; Simultaneously, adopt this deashing device also can improve the casing width of pulsed bag dust collector, make casing bag chamber width bring up to 4.5-6.5 rice by present about 3 meters, can improve existing single device greatly in conjunction with other correlation techniques and handle air quantity, be development process air quantity 1,000,000-2000000m
3/ h wide casing gas tank formula the bag dust collector that maximizes provides technical guarantee.

The specific embodiment
Shown in Fig. 2,3, a kind of deashing device that is used for box pulse packet deduster, on the casing of air-purifying chamber 6 both sides of 10 tops, each bag chamber, correspondence is provided with two group pulse valve 2A1,2B1 and 2A2,2B2.Wherein pulse valve 2A1,2A2 are set in parallel on the casing of air-purifying chamber one side, and pulse valve 2B1,2B2 are set in parallel on the casing of air-purifying chamber 6 opposite sides.
Two group pulse valves are carried out one after the other and are used: when unlatching is set in parallel in pulse valve 2A1,2A2 on air-purifying chamber one side box body, form a best deashing zone (seeing accompanying drawing 4,5) near the air-purifying chamber of pulse valve 2B1,2B2 one side and filter chamber; When unlatching is set in parallel in pulse valve 2B1,2B2 on air-purifying chamber one side box body, near the air-purifying chamber of pulse valve 2A1,2A2 one side and filter chamber, form a best deashing zone (seeing accompanying drawing 6,7); When opening the pulse valve 2A1, the 2B2 that are arranged on air-purifying chamber two side box bodies or 2A2,2B1, then the mid portion at air-purifying chamber and filter chamber forms a best deashing zone (seeing accompanying drawing 8,9) when staggered.Deashing order by the two group pulse valves set successively, carry out the one after the other of two group pulse valves and open use, to the appointed area deashing of fixing a point, make the indoor filter bag of same bag can both obtain essentially identical pulse dust cleaning pressure, obtain essentially identical ash-removal effect, realize the purpose of the even deashing of filter bag that same bag is indoor.On-the-spot operation actual measurement indoor negative pressure of each bag and filtration pressure difference are equal substantially.
