Description

Technical Field

[0001] The utility model relates to the technical field of water film dust collectors, in particular to a water film dust collector with an improved spraying mechanism. Background Art

[0002] Water film dust collector: It is mainly composed of the main cylinder, the upper water injection tank, the lower overflow hole, the cleaning hole, etc. Its working principle is: the dust-laden airflow enters the cylinder through the inlet flue. It is a purification device that uses the dust-laden gas to impact the inner wall of the dust collector or other special components to form a water film in a certain way, so that the dust is captured by the water film and the gas is purified. It includes various categories such as impact water film, inert (shutter) water film and centrifugal water film dust collector. The dust-laden gas is introduced tangentially from the lower part of the cylinder, rotates and rises, and the dust particles are separated by the centrifugal force and thrown to the inner wall of the cylinder. They are adsorbed by the water film layer flowing on the inner wall of the cylinder, flow to the bottom cone with the water, and are discharged through the dust discharge port. The water film layer is formed by several nozzles arranged on the upper part of the cylinder, spraying water tangentially to the wall of the device. In this way, the inner wall of the cylinder is always covered with a thin water film that rotates and flows downward, so as to achieve the purpose of improving the dust removal effect.

[0027] Brief description of the use process: During the use of the device, first, the cleaning liquid required for spraying is poured into the water supply tank 14 through the water supply pipe 21, and then the second water pump 19 is turned on. The second water pump 19 draws water from the water supply tank 14 through the suction pipe 18, outputs it to the cylinder 81, and impacts the baffle 83 inside the cylinder 81, so that the baffle 83 drives the rotating rod 82 to rotate, and then the water is discharged from the outlet pipe 17 to the inside of the rotating tube 4, and finally flows into the water collecting tank 6.

[0030] The upper right side of the water supply tank 14 is connected to a water supply pipe 21, and the left side of the top of the outer shell 2 is bolted with an exhaust pipe 22, so that the water supply pipe 21 can inject cleaning liquid used to purify the exhaust gas into the water supply tank 14, so that the device can discharge the gas after dust removal from the outer shell 2 through the exhaust pipe 20.

[0031] A drain pipe 23 is bolted to the lower part of the left side of the shell 2, and the surface of the drain pipe 23 is connected to a solenoid valve 24. The dust and sewage after filtering and purification are discharged from the shell 2 through the drain pipe 23. This process can be controlled by the solenoid valve 24.
