Description
Safety device for collecting coal gas and yellow phosphorus during water seal pollution discharge
Technical Field
The utility model belongs to the technical field of yellow phosphorus tail gas collection and treatment, and particularly relates to a safety device for collecting coal gas and yellow phosphorus during water seal pollution discharge.

A large amount of tail gas is generated in the production process of yellow phosphorus, and CO, phosphorus, sulfur and the like are contained in the tail gas, so that the direct emission not only causes the waste of resources, but also causes pollution to the environment, and therefore, the tail gas of the yellow phosphorus needs to be purified and reused. After a series of treatments, the yellow phosphorus tail gas is finally discharged by being led into a U-shaped water seal. However, the U-shaped water seal has large curve resistance and is easy to block phosphorus, so that the prior art commonly adopts a pipeline connected to a collecting tank at the bottom of the U-shaped water seal, and the U-shaped water seal is regularly cleaned by draining and discharging through valve control. Chinese patent CN203803322U discloses a yellow phosphorus tail gas recovery and purification device, which can recover CO in yellow phosphorus tail gas; chinese patent CN103322244a discloses a novel U-shaped pipe gas water seal, which is provided with a circulating ammonia water pipeline at one side of the U-shaped water seal, and is used for heat supply and heat preservation of the water seal, so as to reduce the emission of combustible gas. However, a better solution is not provided for the problem that the drain pipe arranged at the U-shaped water seal pipeline and at the bottom is easy to be blocked. Meanwhile, partial CO, phosphorus and sulfur still remain in the U-shaped water seal, and direct discharge is easy to cause environmental pollution.
