The utility model adopts a large-sized pulse valve, increases service life, and reduces maintenance workload; meanwhile, the utility model uses a low pressure and large airflow dust removing mode, overcomes the problem of intense expansion of a cloth bag for dust removal with high and medium pressure, prolongs service life of the cloth bag, simultaneously reduces energy consumption and has the advantages of simple structure and small ground occupation.
Description
Technical field
The utility model relates to a kind of deashing device, is meant a kind of device that has the rotary air pipe, can adopt action of low-voltage pulse air flow cleaning dust especially.
Background technology
Sack cleaner is widely used in flue gas, the gas cleaning that coal-burning boiler, metallurgy, building materials etc. produce the dust occasion.Dusty gas is by the cloth bag filtration, dust is blocked in outside the bag, purified gas passes through and outwards discharging in cloth bag, and be provided with one the cover corresponding soot cleaning system, after deduster work a period of time, under the control of pulse valve, by nozzle blowback in cloth bag, cloth bag outside adhered dust is blown off, to recover the through-current capacity of deduster.In the existing sack cleaner, filter bag becomes row to arrange on orifice plate, every row's bag has 12-16 filter bag, adopt the fixed pulse nozzle to blow every row's filter bag during deashing, numerous small-sized pulse valves need be set, this kind structural device is huge, the energy consumption height, and numerous pulse valves bring heavy operation and maintenance load, in addition useful large-scale pulse valve adds the rotation nozzle, a pulse valve more than 1000 filter bag of can jetting, and system is too huge, therefore how to provide a kind of simple in structure, occupation of land is little, cost is low and manage simple deashing device, becomes the difficult problem that industry is needed solution badly.
The utility model content
The purpose of this utility model is to provide a kind of low pressure rotary pulse ash remover, adopts structures such as pulse valve and swivel nozzle, can address the above problem effectively.
The utility model purpose adopts following technical proposals to realize:
A kind of low pressure rotary pulse ash remover, comprise air inlet pipe and deduster case, the air inlet pipe is provided with control valve and air gauge, low pressure gasholder is established in air inlet pipe below, the low pressure gasholder below connects pulse valve, central authorities are provided with air hose in the deduster case, the air hose top is connected with pulse valve and motor, the air hose below is connected with horizontal airduct, horizontal airduct below is provided with can jet downwards nozzle, is provided with the round plate below the nozzle, and the round plate is fixed on the deduster case, the round plate is provided with a plurality of filter bags hole, and filter bag hole correspondence is connected with filter bag; Described horizontal airduct is more than 1.
The utlity model has following advantage:
1. the utility model has adopted large-scale pulse valve, and valve size can be the 8-12 inch, the intensity height, and corresponding diaphragm is obviously thickening reinforcement also, and service life has also obtained reinforcement, has significantly reduced the workload of maintenance.
2. the utility model adopts low pressure, atm number deashing pattern, has overcome the violent problem that expands of the cloth bag high, that middle pressure deashing brings, and has prolonged the life-span of cloth bag, has also reduced energy consumption simultaneously.
3. the utility model only need be controlled a pulse valve and can operate, and management is simple.
4. the utility model is simple in structure, takes up an area of to lack, and cost is low, is convenient to promote the use of.

Fig. 1 is the utility model structural representation.
Number in the figure is described as follows:
1-air inlet pipe 2-deduster case 3-control valve 4-air gauge
5-low pressure gasholder 6-pulse valve 7-motor 8-air hose
The horizontal airduct 10-of 9-nozzle 11-round plate 12-filter bag
The specific embodiment
As shown in Figure 1, a kind of low pressure rotary pulse ash remover of the utility model, comprise air inlet pipe 1 and deduster case 2, air inlet pipe 1 is provided with control valve 3 and air gauge 4, low pressure gasholder 5 is established in air inlet pipe 1 below, low pressure gasholder 5 belows connect pulse valve 6, central authorities are provided with air hose 8 in the deduster case 2, air hose 8 tops connect pulse valve 6 and motor 7, and air hose 8 belows are connected with horizontal airduct 9, and horizontal airduct 9 belows are provided with can jet downwards nozzle 10, nozzle 10 belows are provided with round plate 11, round plate 11 is fixed on the deduster case 2, and round plate 11 is provided with a plurality of filter bags hole, and below, filter bag hole is connected with filter bag 12; Described horizontal airduct 9 is 3.
In the foregoing description, adopted 8 inches pulse valves, pulse dust cleaning pressure is 0.08～0.15Mpa, and air consumption is 35～40m
3/ min, the pulse dust cleaning time is 0.02s/ time.
Operation principle: low pressure gasholder is exported the action of low-voltage pulse air by pulse valve to air hose, the air hose below imports air in the horizontal airduct of below connection, the rotation of motor-driven air hose, air hose drives horizontal airduct rotation, circular motion by nozzle under the horizontal airduct is blown into low pressure gas each filter bag successively, to blow off attached to dust stratification on the filter bag, reach deashing and the purpose of recovering the pure qi (oxygen) flux; Air gauge is used for showing atmospheric pressure value, adjusts the air inflow that control valve can be adjusted the air inlet pipe, makes atmospheric pressure value remain on certain scope.
