Abstract

The invention discloses a desulfurizing absorption tower wall cleaning device. The device comprises a water spray device, a water supply device connected with the water spray device and a water supply control device, wherein the water spray device is arranged at the top of a washing concentration section arranged in a desulfurizing absorption tower and comprises a circular pipe and a plurality of water spray nozzles, the circular pipe extends along the circumference of the inner wall of the desulfurizing absorption tower, and the water spray nozzles are arranged on the circular pipe, communicated with the circular pipe and used for spraying water to the inner wall of the desulfurization absorption tower; a through hole is formed in the wall of the desulfurizing absorption tower, the water supply device comprises a connecting pipe, one end of the connecting pipe penetrates the through hole to be communicated with the circular pipe, and the other end of the connecting pipe is used for being connected with a water supply pipe; the water supply control device comprises an electric valve arranged on the water supply pipe and a controller which is connected with the electric valve to control the opening and closing of the electric valve. The invention provides the desulfurizing absorption tower wall cleaning device capable of removing salt precipitated out of the tower wall and solves the technical problem of system shutdown caused by damage to equipment due to salt precipitated out of the desulfurizing absorption tower wall and hung to the wall.

Description

technical field [0001] The invention relates to a wet process desulfurization device. Specifically, the utility model relates to a tower wall cleaning device of a desulfurization absorption tower. Background technique [0002] The wet process desulfurization absorption tower is currently widely used in electric power, smelting, chemical and other industries. It uses a certain concentration of ammonia water as the absorbent. The final desulfurization by-product is ammonium sulfate that can be used as agricultural fertilizer. The desulfurization system consists of a pre-washing system, It is composed of mist system, ammonia absorption system, ammonium sulfate drying system, electrical control system, etc. During the operation of the desulfurization device, the high-temperature and high-speed flue gas often causes the salt in the slurry to precipitate on the tower wall in the washing and concentrating section, causing the tower wall to hang on rocks. A large amount of salt acc...
