Description
Technical Field
[0001] The utility model relates to the technical field of scrubbers, in particular to a spiral scrubber. Background Art
[0002] A scrubber is a type of wet dust collector. It uses a liquid (usually water) to remove dust. Typical pool-type scrubbers include the Rotoclan N scrubber and the Doyle scrubber. The "impact-type dust removal unit" described in the second issue of Metallurgical Safety magazine in 1974 features a Rotoclan N scrubber. It consists of a water tank, an air inlet chamber, an S-shaped blade channel, a damper, an exhaust pipe, an electronic water level control device, and an overflow device. This type of scrubber must have the induced draft fan positioned after the exhaust port and operates under negative pressure. Because of this negative pressure operation, a dry cyclone dust collector cannot be added before the scrubber for pre-dust removal to reduce the amount of dust handled in the flue gas. Negative pressure operation results in a narrow range of optimal water levels and poor operational stability. The water levels on either side of the S-shaped blade channel vary, creating difficulties in manufacturing and operational management. Negative pressure operation requires stringent sealing requirements for the scrubber. Furthermore, the use of electrical control equipment for water level control is both expensive and requires frequent maintenance.
[0003] However, the existing scrubber is not convenient for cleaning the inside of the scrubber, which results in impurities remaining on the inner wall of the scrubber, thereby affecting the washing effect of the scrubber, and further causing the problem of poor washing effect of the scrubber.
