Abstract

The invention provides a calcination tail gas treatment device, which includes a deposition device, a rinsing device and an exhaust device. The deposition device is provided with a deposition air inlet and a deposition exhaust port. Baffle plate; the showering device is provided with a showering inlet, a showering outlet and a spraying device, the spraying port of the showering device is set in the showering device, and the showering inlet is arranged under the spraying port , the rinsing exhaust port is arranged above the spray port, and the rinsing air inlet and the deposition exhaust port are sealed and connected through the transmission pipeline; the exhaust device includes an exhaust pipeline and an exhaust fan arranged on the exhaust pipeline, and the exhaust pipeline It is tightly connected with the rinse exhaust port. The calcination tail gas treatment device of the present invention can effectively avoid the problem that the tail gas rich in water vapor and smoke is deposited in the recovery pipeline, and the large-particle ammonium molybdate and molybdenum oxide powder can be recovered by the deposition device, which improves the recovery efficiency and only contains The tail gas with fine particles enters the washing device, and the purification effect of the tail gas is better.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a calcination tail gas treatment device. Background technique [0002] During the calcination process of ammonium molybdate, water, ammonia gas and molybdenum oxide are produced, and the tail gas of ammonium molybdate calcination also contains water vapor, ammonia gas, ammonium molybdate and molybdenum oxide powder, and the tail gas has a large amount of dust and moisture. During the exhaust gas recovery process, particulate matter is easy to deposit on the pipe wall, causing pipe blockage, and the pipe needs to be dismantled frequently for cleaning. The existing ammonium molybdate tail gas recovery treatment mostly adopts the water washing method, and a large amount of dry particles are mixed with water, the recovery efficiency is low, and the amount of water is also large. Contents of the invention [0003] The technical problem to be solved by t...
