The invention will be further explained with reference to the drawings:
FIG. 1 is a schematic sectional view of the present invention,
figure 2 is a schematic view of a partially enlarged structure at a in figure 1,
fig. 3 is a circuit diagram of the present invention.
In the figure: the device comprises a pressure sensor 1, a one-way valve 2, an electromagnetic pulse valve 3, an air bag 4, a dust removal box 5, an air inlet pipe 6, a cover plate 7, an electric heating fan 8, a hot air pipe 9, a filter bag 10, an injection pipe 11, a pattern plate 12, a rubber plate 13, a spring 14 and an ash bucket 15.
K01-K06 in FIG. 3 are electromagnetic pulse valves.
Detailed Description
As shown in fig. 1 to 3, a pulse dust collector suitable for wet dust comprises a dust collection box 5, a flower plate 12 is arranged in the dust collection box 5, a plurality of filter bag 10 frames are arranged on the flower plate 12, each filter bag 10 frame is sleeved with a dust collection filter bag 10, a plurality of injection pipes 11 are arranged in the dust collection box 5 above the flower plate 12, an electromagnetic pulse valve 3 is arranged at one end of each injection pipe 11, an ash hopper 15 is communicated at the lower end of the dust collection box 5, an air inlet pipe 6 is communicated on the ash hopper 15, the pulse dust collector also comprises an electric heating fan 8, an exhaust port of the electric heating fan 8 is communicated with the ash hopper 15 through a hot air pipe 9, the flower plate 12 is connected with the dust collection box 5 through a plurality of springs 14, gaps are arranged between the periphery of the flower plate 12 and the dust collection box 5, rubber plates 13 are arranged at the periphery of the flower plate 12, one end of each rubber plate 13 is abutted against the inner wall of the dust collection box 5, the rubber plates 13 are used, the whole of the card 12 starts shaking, thereby improving the dust falling efficiency of the filter bag 10.
The utility model discloses a theory of operation does: after pulse dust collector used a period, be infected with moist dust more and more on the filter bag 10 gradually, therefore made the resistance of filter bag 10 increase gradually, the quantity of gas through filter bag 10 reduces gradually, along with air exhaust fan's continuous operation, the pressure reduces gradually in the dust removal case 5 in the upper side of card 12, when pressure reduces to 120 millimeters water column, then need clear up the adhesion dust on the filter bag 10, the clearance process is: the pulse dust collector is paused, then the electric heating fan 8 is started, hot air with the temperature of 100 to 120 ℃ is filled into the dust collection box 5, after 10 minutes, the dust adhered to each filter bag 10 is completely dried, the dust loses viscosity, then the electromagnetic pulse valve 3 is started, after two periods of pulse compressed air blowing, the dust adhered to the dust collection filter bag 10 is cracked and falls off, the adhered dust in the meshes of the filter bags 10 is blocked by the emptying plugs, and the pulse dust collector can be continuously used.
The air inlet pipe 6 and the hot air pipe 9 are both hinged with a cover plate 7. The cover plate 7 mainly has the function of one-way conduction at one end of the air inlet pipe 6 and one end of the hot air pipe 9, and can prevent dust from entering the electric heating fan 8 when the pulse dust collector is normally used; when the dust adhered to the filter bag 10 is removed, hot air can be prevented from entering the air inlet pipe 6, and then hot air waste is avoided.
One end of the injection pipe 11 close to the electromagnetic pulse valve 3 is provided with a one-way valve 2. The temperature resistance of the electromagnetic pulse valve 3 is generally not more than 50 ℃, so that the electromagnetic pulse valve 3 is prevented from being influenced by hot air blown out by electric hot air, the check valve 2 is additionally arranged again, and the influence of hot air in the dust removing box 5 on the electromagnetic pulse valve 3 along the blowing pipe 11 is prevented.
