Abstract
The utility model discloses a device is arranged outward to final cooling tower, including final cooling tower, blow-down pipe, circulating pump and outer collection groove of arranging, first circulating pump is connected through the blow-down pipe in the final cooling tower bottom, first circulating pump passes through the pipeline and carries outer flowing back to arrange the collection groove in, has avoided impurity such as tar to get into the final cooling tower packing layer once more, has alleviated the situation that final cooling tower resistance rises too fast, reduces the frequency of washing the tower.
Description
Technical Field
The utility model relates to a final cooling tower field, specifically speaking, the utility model relates to a device is arranged outward to final cooling tower.
Background
The discharge system of the final cooling tower at the crude benzene recovery section of the coking plant is originally arranged at the outlet of the final cooling circulating spray pump, when the system is operated, impurities such as tar in coal gas can be deposited at the bottom of the final cooling tower and enter the packing layer of the final cooling tower again along with the circulation of the circulating pump, so that the packing is blocked, the tower resistance is increased, and the coal gas conveying is influenced. When the tower resistance is increased, the tower needs to be stopped for cleaning, and the operation of a crude benzene working section is influenced.
Disclosure of Invention
For solving the technical problem, the utility model provides a final cooling tower outer discharging device utilizes the last installation circulating pump of blow-down pipe to directly arrange the outer collection groove of arranging into with outer flowing back.
In order to achieve the technical purpose, the utility model adopts the following technical proposal;
the utility model provides a device is arranged outward to end cold tower, includes end cold tower, blow-down pipe, circulating pump and outer collection groove of arranging, and is further, the circulating pump divide into first circulating pump and second circulating pump, end cold tower bottom is through blow-down pipe connection first circulating pump, first circulating pump passes through the pipeline and carries outer flowing back to arrange in the collection groove outward.
Furthermore, the bottom of the final cooling tower is connected with a second circulating pump through a pipeline, the second circulating pump is connected with a heat exchanger through a pipeline, the heat exchanger is connected to the upper portion of the final cooling tower through a pipeline, and a spraying unit is arranged at the end portion of the pipeline and sprays into the final cooling tower.
Further, the first circulating pump is a centrifugal pump.
Furthermore, the first circulating pump is provided with a valve, and an outlet of the valve is connected with a pipeline and led into the outer discharge groove.
Advantageous effects
Through the implementation of the scheme, a centrifugal pump is directly installed on the vent pipe at the bottom of the final cooling tower and used for conveying external drainage liquid, so that impurities such as tar are prevented from entering the packing layer of the final cooling tower again, the situation that the resistance of the final cooling tower rises too fast is relieved, and the frequency of washing the tower is reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
description of the symbols:
1. the system comprises a final cooling tower, 2. a first circulating pump, 3. an emptying pipe, 4. a pipeline, 5. an outer discharge groove, 6. a second circulating pump, 7. a heat exchanger and 8. a spraying unit.
Detailed Description
In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.
As shown in fig. 1, the external discharge device of the final cooling tower comprises a final cooling tower 1, an emptying pipe 3, a first circulating pump 2, a second circulating pump 6 and an external discharge base tank 5; wherein 1 bottom of final cooling tower is passed through blow-down pipe 3 and is connected first circulating pump 2, and first circulating pump 2 passes through pipeline 4 and carries the outer flowing back that produces in the final cooling tower to arrange in the collection groove 5, and preferred, first circulating pump 2 is the centrifugal pump to first circulating pump is equipped with the valve, the exit linkage pipeline 4 of valve.
The bottom of the other end of the final cooling tower 1 is connected with a second circulating pump 6 through a pipeline 4, the other end of the second circulating pump 6 is connected with a heat exchanger 7 through the pipeline 4, the heat exchanger 7 is connected to the upper portion of the final cooling tower 1 through the pipeline 4, a spraying unit 8 is connected to the end portion of the pipeline 4, when the automatic washing device works, steam circularly enters the final cooling tower 1 through heating of the heat exchanger 7, sundries in a filling material layer in the final cooling tower 1 are washed in a hot washing mode, a centrifugal pump is preferably used as the first circulating pump 2 on the side of an emptying pipe, and the cleaned sundries are pumped out of the final cooling tower 1 and discharged into an outer discharge collection tank 5.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention, and any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
