And a liquid level meter and a pressure gauge are arranged in the tail gas collecting tank. The utility model has the advantages that: 1. the recovery of ammonia tail gas is ensured, the problem of ammonia overflow is solved, and the pollution of ammonia to the environment is effectively avoided; 2. can realize long-term stable operation.
Description
Technical field
The utility model relates to the device of a kind of separating tar in coking field and ammoniacal liquor.
Background technology
Mechanizeding ammonia clarifying groove is the equipment that coal chemical enterprise is used to separate ammoniacal liquor, tar and tar slag, the ammoniacal liquor on defecator top through the top overflow to the cyclic ammonia water groove, ammonia tail gas above the liquid directly is discharged in the atmosphere, not only causes a large amount of ammonia losses, and causes surrounding environment poor.
Summary of the invention
The purpose of this utility model provides a kind of mechanizeding ammonia clarifying groove device for recovering tail gas, can effectively reduce tail gas pollution, washing back qualified discharge.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of mechanizeding ammonia clarifying groove device for recovering tail gas comprises exhaust collection groove, wash mill, and described exhaust collection groove top is provided with air extractor, and air extractor is connected with the exhaust collection groove by connecting pipe, is provided with the tail gas recycle pump on connecting pipe.
Described wash mill is provided with shower nozzle with the position that is communicated with of exhaust collection groove, and shower nozzle is connected with new waterpipe.
Be provided with liquid level gauge and Pressure gauge in the described exhaust collection groove.
Compared with prior art, the utility model has the advantages that:
1, guaranteed the recovery of ammonia tail gas, solved the excessive problem of ammonia, stopped the pollution of ammonia effectively environment.；
2, can realize operation steady in a long-term.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the new waterpipe 7-of 1-tail gas pump 2-exhaust collection groove 3-shower nozzle 4-air extractor 5-wash mill 6-liquid level gauge 8-Pressure gauge
The specific embodiment
See Fig. 1, a kind of mechanizeding ammonia clarifying groove device for recovering tail gas comprises tail gas recycle groove 2, air extractor 4, wash mill 5, and tail gas recycle groove 2 is airtight relatively cell body, and cell body top is connected with air extractor 5; Air extractor 5 is connected with exhaust collection groove 2 by connecting pipe, and exhaust collection groove 2 is provided with tail gas pump 1, is provided with shower nozzle 3 with the position that is communicated with of exhaust collection groove 2 in the wash mill 5, and shower nozzle 3 is connected with new waterpipe 6.Be provided with liquid level gauge 7 and Pressure gauge 8 in the exhaust collection groove 2.
1 circulation of tail gas pump is sprayed, rely on and spray the ammonia that the negative pressure that produces sucks exhaust collection groove 2, the tail gas that reclaims enters atmosphere after washing, unnecessary liquid in the exhaust collection groove 2 is discharged in the mechanical settling tank 2, realize benign cycle, be provided with liquid level gauge 7 and Pressure gauge 8 simultaneously, the liquid level of exhaust collection groove 2 is controlled between the certain limit by liquid level gauge 7 and Pressure gauge 8, guarantee to leave certain space above the exhaust collection groove 2, the tail gas that negative pressure absorbs can discharge smoothly.
