Description

Technical Field

[0001] This utility model relates to the technical field of dust collection devices, specifically to a dust collection device for a pipeline dust removal slag outlet. Background Technology

[0002] During the operation of industrial boilers such as coal-fired boilers and blast furnace steelmaking, the ash and slag produced after fuel combustion must be discharged through the ash discharge pipes in a timely manner. The ash and slag contain a large amount of particulate dust, which, if not effectively treated, will cause serious environmental pollution. Therefore, dust removal treatment is necessary for the boiler ash discharge pipes.

[0003] In existing technologies, by setting up a gravity settling chamber and connecting the slag discharge pipe to a closed compartment to allow ash and slag to settle naturally, the dust reduction efficiency is low. Utility Model Content

The spraying mechanism is connected to one side of the housing, and the negative pressure vacuum cleaner is fixedly connected to the upper end of the housing. The upper end of the housing is provided with a plurality of suction ports, and the negative pressure vacuum cleaner is interconnected with the suction ports. A slag outlet is provided on the other side of the housing.

[0026] like Figure 1 , 2 As shown in Figures 5 and 6, a dust collection device for a pipeline dust removal slag outlet includes a housing 2, which is fixedly connected to the lower end of a pipeline 1. The upper end of the housing 2 has a slag inlet 201 connected to the pipeline 1. It also includes a spraying mechanism 3 and a negative pressure vacuum cleaner 4. The spraying mechanism 3 is connected to one side of the housing 2, and the negative pressure vacuum cleaner 4 is fixedly connected to the upper end of the housing 2. The upper end of the housing 2 has several suction ports 203, and the negative pressure vacuum cleaner 4 is interconnected with the suction ports 203. The other side of the housing 2 has a slag outlet 205. Several inclined baffles 204 are fixedly connected to the top surface of the inner wall of the housing 2, and these baffles 204 are respectively located at the suction ports 205. 3. The bottom surface of the inner wall of the box 2 is inclined. The slag outlet 205 is located at the lower end of the inclined bottom surface. The outer side of the box 2 is fixed with a collection hopper 206 that communicates with the slag outlet 205. The ash slag is discharged from the slag outlet 205 along the inclined bottom surface and then collected by the collection hopper 206. The dust is sprayed and settled by the spraying mechanism 3. The unsettled dust and mist move with the ash slag towards the slag outlet 205 of the box 2. When passing through several dust suction ports 203, they are sucked up and collected by the negative pressure vacuum cleaner 4. The inclined baffle 204 can block the dust and mist, thereby promoting the dust and mist to enter the dust suction port 203 and be sucked up by the negative pressure vacuum cleaner 4.

[0027] like Figure 3-5As shown, the spraying mechanism 3 includes a water tank 301, a water pump 305, and a spray box 308. The water tank 301 has an inlet 302 at its upper end, and a sealing cap 304 is inserted into the inlet 302. The spray box 308 is inserted into one side of the housing 2 and extends into the housing 2. The water tank 301 is movably mounted on one side of the housing 2. The water pump 305 is fixed to the upper end of the water tank 301 and drives the water in the water tank 301 into the spray box 308. The water is then sprayed out from inside the housing 2. The water pump 305 has a suction pipe 306 and a delivery pipe 307 fixedly connected to both ends. The water tank 301 has a through hole 303. The suction pipe 306 passes through the through hole 303 and extends into the bottom of the water tank 301. The delivery pipe 307 is fixedly connected to the upper end of the spray box 308 and communicates with its interior. The housing 2 has an installation port 202 on one side. The front end of the spray box 308 is inserted into the installation port 202. A plurality of nozzles 309 are fixedly connected to the front end of the spray box 308. A limiting frame 310 is fixedly connected to the outside of the spray box 308. A rubber sealing strip 313 is fixedly connected to one side of the limiting frame 310. The rubber sealing strip 313 is pressed against one side of the box body 2. The sealing connection between the spray box 308 and the box body 2 is achieved by the box body 2 and the limiting frame 310 pressing the rubber sealing strip 313. The limiting frame 310 has symmetrically distributed mounting plates 311 fixed at both ends. The mounting plates 311 are designed with an L-shaped structure. The two mounting plates 311 are fastened to the front and rear sides of the box body 2. Bolts 312 that are spirally connected to the box body 2 are passed through the mounting plates 311. The bolts 312 are used to achieve a detachable connection between the spray box 308 and the box body 2. The water in the water tank 301 is controlled by the water pump 305 to spray water from the nozzles 309 at the front end of the spray box 308 inside the box body 2 to the bottom of the pipe 1 inside the box body 2.

[0028] In use, the ash and slag fall into the housing 2 through the pipe 1. At the same time, the water pump 305 draws water from the water tank 301 through the suction pipe 306, and then introduces the water into the spray box 308 through the water delivery pipe 307. The water is then sprayed out from the nozzle 309 to the lower side of the pipe 1 inside the housing 2. The dust in the ash and slag adheres to the water molecules and settles. The dust is discharged from the slag outlet 205 along the inclined bottom surface inside the housing 2 and collected by the collection hopper 206. As the dust and mist in the housing 2 move with the ash and slag, the negative pressure vacuum cleaner 4 sucks the dust inside the housing 2 through the suction port 203, thereby removing the dust and smoke that have not settled inside the housing 2. At the same time, the inclined baffle 204 blocks the dust and smoke, thereby promoting the dust and smoke to enter the suction port 203 and be sucked up by the negative pressure vacuum cleaner 4.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
