Technical Field
The utility model relates to the technical field of dust removal devices, in particular to an unpowered water spraying dust removal device for a guide chute of a belt conveyor of a coal conveying system.
Background
At present, many thermal power plants in China still adopt coal as fuel, so that a large amount of dust-containing smoke such as suspended particulate matters and sulfur dioxide is brought. In a thermal power plant, a dust collector is one of the essential and important auxiliary equipments of a coal conveying system. Most of the existing thermal power plants select high-voltage electrostatic dust removal, but the high-voltage electrostatic dust remover has poor dust removal effect and spontaneous combustion problem in operation. In addition, when the dust remover operates, a high-voltage electric field in the body does work to enable dust to be adsorbed on the negative plate, but when other impurities are adsorbed or the polar plate is corroded and falls off to cause short circuit of the negative electrode and the positive electrode, the dust is enabled to be self-ignited, and therefore fire disasters occur.
Therefore, there is a need to design a non-powered water spraying dust removing device for a guide trough of a belt conveyor of a coal conveying system to solve the above defects and problems.

The spray assembly 34 is mounted within the separation zone conduit 32 and the spray header 341 is connected to spray related equipment.
Preferably, the filter screen 35 covers the air outlet of the separation zone conduit 32. The filter screen 35 is bound to the cylindrical holder 37 and then placed on the water collection tray 33. When placed, the center of the support 37 coincides with the center of the separation zone conduit 32. Finally, the conical dust exhaust pipe 36 is sleeved on the filter screen bracket.
See FIG. 6
Preferably, the filter screen 35 may be, but is not limited to, cylindrical or rectangular parallelepiped. The filter screen 35 is fixed to the side of the outlet of the separation region conduit 32 by a bracket 37. The holder 37 includes a loop-shaped support 371 and at least two legs 372 fixed to the outer periphery of the loop-shaped support 371.

Preferably, the base 11 and the dust hopper 21 and the dust channel 22 and the hopper 31 are connected by flanges 4.
The dust removal process of the device is as follows:
the gas dust is guided by the guide plate 121, enters the dust collecting hopper 21 through the base 11, then enters the hopper 31 through the dust channel 22, and enters the separation region pipeline 32. At this time, the spraying unit 4 is already in operation, the water sprayed from the spraying pipe 341 is atomized into water mist by the water mist forming block 342, the atomized water mist covers the entire separation region pipe 32, the dust and the spraying water mist are mixed to become coal water, and the coal water flows along the pipe wall to the dust discharging hopper 23 below the dust channel 22 under the action of gravity and then flows into the ground drainage ditch. In addition, part of the spraying water mist is sprayed out of the separation pipeline area 32 together, the water mist is sprayed onto the filter screen 35, when the gas is discharged to the filter screen 35, the gas is mixed again by water drops on the filter screen 35, and the gas is changed into coal water which flows into the water collecting tray 33 and then flows into the dust exhaust pipe 36. Under the action of gas pressure, a part of dust which is not separated in the separation area pipeline 32 is subjected to dust suppression again through the filter screen 35, and then the dust-free gas is directly discharged to the outside. The other part of the gas discharged through the dust discharge pipe 36 continuously rolls and mixes the dust and the water mist under the action of the self power of the gas in the channel in the pipe to turn into coal water which falls down to the water collecting tray 33, the gas successfully filters the dust in the process, and the discharged gas does not contain dust any more, so that the qualified target of gas discharge is reached.
