Description

Technical Field

[0001] The utility model belongs to the technical field of gray water treatment in chemical production, and specifically relates to a gray water discharge system. Background Art

[0002] Gray water in chemical production is the low-turbidity water generated by the black water produced in the scrubber and vaporizer during the coal-water slurry gasification process. After flash evaporation, sedimentation clarification, and slag removal, this gray water is typically stored in gray water tanks for recycling as water for chemical production. In actual operation, when the amount of gray water entering the gray water tank far exceeds the amount used, the gray water in the tank will overflow and pollute the environment. Therefore, the gray water tank is connected to an external discharge pipe, and a pump is connected to the external discharge pipe to discharge the excess gray water to water treatment equipment for centralized treatment.

[0003] Since the main component of gray water is calcium ions, calcium carbonate, calcium carbonate crystals will adhere to the inner wall of the container or pipe to form scale, causing the pump on the external discharge pipeline to be frequently blocked due to scaling, affecting the discharge of gray water. In severe cases, it will also cause fluctuations in the chemical production system, affecting the safe and stable operation of the chemical production system. Utility Model Content

[0004] In view of the above background technology, the pumps on the existing ash water discharge pipeline are often blocked due to scaling, which affects the discharge of ash water and causes fluctuations in the chemical production system. To address this technical problem, the utility model proposes an ash water discharge system.

[0005] The utility model provides a second external discharge branch pipe on the return main pipe on the basis of the first external discharge branch pipe. When the pump body component is blocked and the gray water cannot be discharged normally through the first external discharge branch pipe, the second external discharge branch pipe can be started, and the gray water is discharged through the cooperation of the return main pipe and the second external discharge branch pipe, ensuring the normal discharge of the gray water, preventing fluctuations in the chemical production system, and thus ensuring the safe and stable operation of the chemical production system.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

When the pump body assembly 3 is blocked by scaling, the return main pipe 5 and the second external discharge branch pipe 62 cooperate as a backup to discharge the gray water.

[0026] The utility model is provided with valve bodies on the output main pipe 4, the return main pipe 5, the first external branch pipe 61 and the second external branch pipe 62, which are used to control the on-off of the corresponding pipelines and adjust the flow of the corresponding pipelines.

[0027] The utility model provides a second external discharge branch pipe 62 on the return main pipe 5. When the pump body assembly 3 is blocked and the gray water cannot be discharged normally through the first external discharge branch pipe 61, the second external discharge branch pipe 62 can be started. The gray water is discharged through the cooperation of the return main pipe 5 and the second external discharge branch pipe 62, ensuring the normal discharge of the gray water, preventing fluctuations in the chemical production system, and thus ensuring the safe and stable operation of the chemical production system.

[0028] The graywater discharge system of the present invention further includes an external discharge conveying pipeline 7, and a first external discharge branch pipe 61 and a second external discharge branch pipe 62 are both connected to the external discharge conveying pipeline 7. Specifically, the external discharge conveying pipeline 7 includes a first external discharge conveying pipeline 71 and a second external discharge conveying pipeline 72.
