Description
Technical Field
The utility model relates to the field of coal coking equipment, in particular to a circulating ammonia oil removing device.
Background
The tar ammonia water separating tank is equipment for gravity settling separation of tar and ammonia water and is of a vertical structure. The tar and ammonia water mixed solution from the gas-liquid separator is separated by the tar-liquid separator, then the tar and ammonia water mixed solution flows from the inlet of the tank to the middle of the separation tank through a sieve plate with sieve holes, ammonia water floats upwards and is collected in an ammonia water overflow tank on the shell wall through a light tar baffle plate and a weir plate, flows into an ammonia water tank formed by a cone bottom and a cylinder body through an ammonia water guide pipe, is discharged from an ammonia water outlet, is sent to a coke oven to cool raw gas through a circulating ammonia water pump. In order to ensure the spraying and cooling effect of the circulating ammonia water and reduce the difficulty of treating the wastewater by subsequent ammonia evaporation, the tar content in the circulating ammonia water must be reduced.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a circulating ammonia oil removing device which can reduce the tar content in circulating ammonia water and ensure the quality of residual ammonia water and the spraying effect of the circulating ammonia water on coke oven gas.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a circulation ammonia water deoiling device, includes preseparator, tar ammonia water knockout drum, circulation ammonia water pump and dredge pump, preseparator passes through the pipeline and is connected with tar ammonia water knockout drum, and tar ammonia water knockout drum passes through the pipeline and is connected with circulation ammonia water pump, sets up the import of tar ammonia water mixed solution on the preseparator, the dredge pump passes through the blow off pipe and is connected with preseparator and tar ammonia water knockout drum respectively.
Preferably, a drain pipe of the drain pump is connected with the bottom of the tar ammonia water separation tank.
Preferably, at least one group of tar and ammonia water separating tanks are arranged.
By adopting the technical scheme of the utility model, the following beneficial effects can be obtained:
the circulating ammonia oil removing device can greatly reduce the tar content in the circulating ammonia, ensure that coke oven gas can be effectively cooled, reduce the blockage of a ceramic filter and an ammonia distillation tower, and effectively control the indexes of the circulating ammonia (the oil content of the circulating ammonia is less than 50mg/L and the oil content of the residual ammonia is less than 20 mg/L).

The following is a brief description of what is expressed in the drawings of this specification and the references in the drawings:
FIG. 1 is a schematic diagram of the structure of the circulating ammonia oil removal device;
the labels in the above figures are: 1. a sewage pump; 2. a blow-down pipe; 3. a preseparator; 4. a tar ammonia water separation tank; 5. circulating ammonia water pump.
Detailed Description
The following describes the shape, structure, mutual position and connection relation between the parts, action and working principle of the parts, etc. of the specific embodiments of the present utility model, such as the related parts, will be further described in detail by describing examples.
As shown in fig. 1, the circulating ammonia oil removing device comprises a preseparator 3, a tar ammonia water separating tank 4, a circulating ammonia water pump 5 and a sewage pump 1, wherein the preseparator 3 is connected with the tar ammonia water separating tank 4 through a pipeline, the tar ammonia water separating tank 4 is connected with the circulating ammonia water pump 5 through a pipeline, an inlet of a tar ammonia water mixed solution is arranged on the preseparator 3, the sewage pump 1 is respectively connected with the preseparator 3 and the tar ammonia water separating tank 4 through a sewage pipe 2, the sewage pipe 2 of the sewage pump 1 is connected with the bottom of the tar ammonia water separating tank 4, at least one group of tar ammonia water separating tanks 4 is arranged, and a plurality of groups of tar ammonia water separating tanks 4 are connected in a circulating system in parallel through pipelines.
When the device is used, the mixed liquid enters from the inlet of the tar and ammonia water mixed liquid on the preseparator 3, the preseparator 3 is used for preseparating tar and ammonia water, the separated mixed liquid is pumped into the tar and ammonia water separating tank 4 for further separation of tar and ammonia water, the mixed liquid with heavier specific gravity and higher coke content after separation is deposited at the bottom of the tar and ammonia water separating tank 4, and the mixed liquid is pumped into the preseparator 3 through the sewage pump 1 for circulating separation until the circulating ammonia water index is effectively controlled. The sewage pump 1 circularly pumps the tar at the bottom of the outer tank of the tar ammonia water separation tank 4, and the tar runs for 24 hours, so that a closed circulation system is formed by the sewage pump, the pre-separator 3 and the tar ammonia water separation tank 4.
The oil removal method can greatly reduce the tar content in the circulating ammonia water, ensure that coke oven gas can be effectively cooled, reduce the blockage of a ceramic filter and an ammonia still, and effectively control the index of the circulating ammonia water (the oil content of the circulating ammonia water is less than 50mg/L and the oil content of the residual ammonia water is less than 20 mg/L).
While the utility model has been described above with reference to the accompanying drawings, it will be apparent that the utility model is not limited to the above embodiments, but is capable of being modified or applied directly to other applications without modification, as long as various insubstantial modifications of the method concept and technical solution of the utility model are adopted, all within the scope of the utility model.
