Description

Technical Field

[0001] The utility model relates to the technical field of boiler slag discharge, in particular to a dust suppression device for boiler slag discharge. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy.

[0003] When the existing boiler is in use, the medium burned will form slag after combustion, so it is necessary to perform slag discharge operation regularly. At present, when the boiler is discharged, in order to avoid dust, a dust reduction device is often used to reduce dust at the discharge port. Most of the current dust reduction devices are atomizing nozzles. When the slag is discharged, the atomizing nozzle sprays water to the slag surface to reduce dust, but the spray can only adhere to the upper layer of slag on the surface. When the slag shakes, the lower layer of slag will turn over, so dust will still occur, and the dust reduction effect is not good. Therefore, we propose a dust reduction device for boiler slag discharge. Utility Model Content

[0004] The utility model aims to provide a dust reduction device for boiler slag discharge, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dust reduction device for boiler slag discharge, comprising a dust reduction cylinder, the top of which is fixedly connected to a conduit, the outer end of which is fixedly connected to a fixing ring, and the outer wall of which is penetrated by a plurality of evenly distributed electromagnets;

[0006] Annular tubes are fixed on the upper and lower parts of the inner cavity of the dust suppression cylinder, and a plurality of evenly distributed nozzles are fixedly connected to the inner wall of the annular tube. A carrier plate is fixed to the outer wall of the dust suppression cylinder, and a liquid pump is fixed to the outer wall of the carrier plate. One end of the liquid pump is fixedly connected to an external liquid pipe, and the other end of the liquid pump is fixedly connected to a connecting pipe. The outer end of the connecting pipe passes through the dust suppression cylinder and is respectively connected to the two annular tubes.

[0007] By adopting the above technical solution, the fixed ring is aligned with the boiler slag discharge port, and then the electromagnet is energized to allow it to be adsorbed on the outer wall of the boiler. The slag discharged from the slag discharge port then enters the inner cavity of the duct and then enters the inner cavity of the dust reduction tube. Water is pumped out by a liquid pump and then introduced into the inner cavity of the annular tube along the connecting pipe, so that the nozzle can be used to spray the slag descending in the dust reduction tube to reduce dust. The dust reduction effect can be improved through two dust reduction operations.

[0008] As a preferred embodiment of the utility model, a second material guide hopper is fixed in the middle of the inner cavity of the dust suppression cylinder, a conical block is arranged on the upper side of the second material guide hopper, and the bottom of the conical block is fixedly connected to the inner wall of the second material guide hopper through a connecting rod.

[0009] By adopting the above technical scheme, the descending slag is sprayed in all directions for dust reduction through the nozzle located on the inner wall of the upper annular tube to achieve preliminary dust reduction, and then the slag is impacted on the conical block and falls again after tumbling, and then the nozzle on the inner wall of the lower annular tube is used to spray dust reduction again, thereby achieving secondary dust reduction, which can improve the dust reduction effect on the slag and effectively avoid the occurrence of dust after slag discharge.

[0010] As a preferred embodiment of the present utility model, a first material guide hopper is fixed on the top of the inner cavity of the dust suppression cylinder.

[0011] By adopting the above technical solution, the slag entering the dust reduction tube can be centrally guided to the middle of the annular tube, thereby ensuring the accuracy of dust reduction.

[0012] As a preferred embodiment of the utility model, a discharge hopper is fixed to the tail end of the dust suppression cylinder.

[0013] By adopting the above technical solution and setting up the discharge hopper, the slag after dust reduction can be discharged in a centralized manner for easy collection.

[0014] As a preferred embodiment of the utility model, an adaptive rubber ring is fixedly glued to the outer wall of the fixing ring.

[0015] By adopting the above technical solution, the fixing ring can press the rubber ring tightly when the electromagnet is adsorbed on the surface of the device, thereby improving the sealing effect and avoiding dust overflow at the connection.

[0016] As a preferred embodiment of the present invention, a vibration motor is fixed to the outer wall of the conduit.

[0017] By adopting the above technical solution, the setting of the vibration motor makes it possible to transmit the vibration to the conduit, thereby preventing the slag from accumulating in the conduit and causing blockage.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] The dust reduction device for boiler slag discharge of the technical solution of the present application introduces slag into the dust reduction cylinder, and performs all-round spray dust reduction on the descending slag through the nozzle located on the inner wall of the upper annular tube, thereby achieving preliminary dust reduction, and then the slag is impacted on the conical block and falls again after rolling, and then the nozzle on the inner wall of the lower annular tube is used to spray dust reduction again, thereby achieving secondary dust reduction, which can improve the dust reduction effect on the slag, and effectively avoid the occurrence of dust after slag discharge;

[0020] By energizing the electromagnet, the fixing ring can be adsorbed on the outer wall of the filtering device and the rubber ring can be pressed, so that the connection with the slag discharge port can be convenient and quick, and dust overflow at the connection point can be avoided after the connection.
