It will be appreciated by those skilled in the art that coking gas contains a significant amount of impurities such as naphthalene and the like. In the process of cooling the coal gas through the circulating spraying cooling device, the impurities can enter the plate heat exchanger along with circulating spraying liquid, and then the plate heat exchanger is blocked or the heat exchange performance of the plate heat exchanger is reduced.
To the operation degree of difficulty that exists when clearing up plate heat exchanger among the prior art big, the maintenance cost is high, polluted environment scheduling problem, this application provides a plate heat exchanger cleaning system. The plate heat exchanger cleaning system provided by the present application is described in detail below with reference to fig. 1-5.
Referring to fig. 1, a schematic structural diagram of a cleaning system of a plate heat exchanger 10 according to an embodiment of the present application is provided. In the present embodiment, in order to prevent the cleaned naphthalene crystal from drifting into the air and causing environmental pollution, the applicant considers the method of cleaning the plate heat exchanger 10 by using hot ammonia water, in combination with the feature that the melting point of naphthalene is low, and the hot ammonia water in the ammonia water tank 30 can just dissolve the naphthalene impurities in the plate heat exchanger 10.
Specifically, in the embodiment of the present application, the system includes: plate heat exchanger 10, circulation spray cooling device 20, aqueous ammonia tank 30 and force (forcing) pump 31.
A first pipeline and a second pipeline are connected between the circulating spray cooling device 20 and the plate heat exchanger 10, the first pipeline is provided with a first switch valve 21, and the second pipeline is provided with a second switch valve 22. The first and second pipes constitute a circulation loop, when the first on-off valve 21 is opened, the circulating sprayed liquid in the circulating spray cooling device 20 flows to the plate heat exchanger 10 for cooling, and when the second on-off valve 22 is opened, the cooled circulating sprayed liquid flows to the circulating spray cooling device 20 for cooling the gas flowing through the device.
It should be noted that in the embodiment of the present application, the first pipeline and the second pipeline may include a drainage device, such as a pump.
Further, in the present embodiment, the ammonia water tank 30 is connected to the plate heat exchanger 10 through a third pipeline, and a pressure pump 31 is connected to the third pipeline, and a third on/off valve 32 is disposed between the pressure pump 31 and the plate heat exchanger 10. When naphthalene impurities in the gas enter the plate heat exchanger 10 to cause blockage or reduction of heat exchange performance of the plate heat exchanger 10, the first switch valve 21 and the second switch valve 22 are closed, then the third switch valve 32 is opened, and the hot ammonia water in the ammonia water tank 30 can be pressurized through the pressurizing pump 31 and then applied to the plate heat exchanger 10 to clean the plate heat exchanger 10.
In the examples, since the washed naphthalene was mixed in the ammonia water, environmental pollution caused in the air in the drift of the naphthalene crystals could be prevented. Meanwhile, because the cleaning system for the plate heat exchanger 10 provided by the embodiment of the application only needs to open the third switch valve 32 when the plate heat exchanger 10 needs to be cleaned, and the pressurization pump 31 is started, the cleaning system for the plate heat exchanger 10 provided by the embodiment of the application can greatly reduce the operation difficulty when the plate heat exchanger 10 is cleaned compared with the prior art.

When hot ammonia water is introduced into the plate heat exchanger 10 for soaking, normal-pressure hot ammonia water can be introduced into the plate heat exchanger 10 by opening the fifth switch valve 33, then the dissolved naphthalene impurity ammonia water can be discharged to the sewage tank 40 together by opening the fourth switch valve 41 after soaking for 5-10 minutes, finally the plate heat exchanger 10 can be further washed by introducing high-pressure hot ammonia water into the plate heat exchanger 10 by opening the fifth switch valve 33, and the washed ammonia water is discharged to the sewage tank 40 for recycling.

In this embodiment, in order to recycle the sewage stored in the sewage discharge tank 40 after the plate heat exchanger 10 is cleaned, the sewage discharge tank 40 may be connected to the tar-ammonia water separator 60, and then the separated ammonia water is transmitted to the ammonia water tank 30 through the tar-ammonia water separator 60 to be recycled.
In the embodiment of the present invention, in order to further separate the hot ammonia water in the ammonia water tank 30, the ammonia water tank 30 may be connected to the gas-liquid separator 50, so that the ammonia water in the ammonia water tank 30 is circulated to the gas-liquid separator 50 to be again gas-liquid separated, and then the separated condensate is conveyed to the tar-ammonia water separator 60 to be again subjected to tar-ammonia water separation, thereby forming a circulation system.
With continued reference to fig. 4, in an embodiment of the present application, the system further includes a tar tank 61, and the tar tank 61 is connected to the tar-ammonia separator 60 for accommodating the tar separated by the tar-ammonia separator 60.
