Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figures 1 to 3 As shown, an embodiment provided by the present invention: an efficient and environmentally friendly chemical cleaning device includes a heater 8, which is connected to a fuel vapor generator 9 through a steam pipe 22, and uses the steam generated by the fuel vapor generator 9 to heat the cleaning liquid. The right side of the heater 8 is fixedly connected to a main pipe 7 at the pump outlet. Its design should consider factors such as the flow rate, pressure, and corrosiveness of the cleaning liquid to ensure its safety and reliability during long-term operation. Two regulation valves 6 at the pump outlet are fixedly connected to the outside of the main pipe 7 at the pump outlet. The regulation valves 6 at the pump outlet are used to regulate the flow rate of the cleaning liquid. By manually or automatically controlling the opening degree of the regulation valves 6 at the pump outlet, the flow rate of the cleaning liquid flowing from the cleaning pump 1 to the heater 8 and the cleaning object 35 can be precisely controlled. Two pressure gauges 4 at the pump outlet are fixedly connected to the top of the main pipe 7 at the pump outlet. By observing the readings of the pressure gauges 4 at the pump outlet, operators can understand the pressure situation of the cleaning liquid during the pumping process, so as to timely adjust the operating parameters of the cleaning pump 1 or check whether there are problems such as blockage in the system.

[0031] Refer to Figures 2 to 4As shown, two flow meters 5 are fixedly connected to the top of the pump outlet header pipe 7. The readings of the flow meters 5 can help the operator control the flow rate of the cleaning liquid to meet the requirements of different cleaning stages.

[0034] Refer to Figures 1 to 3As shown, during the cleaning process, the opening degree of the return pump inlet valve 15 should be adjusted according to the flow rate and pressure requirements of the cleaning liquid to ensure the normal operation of the cleaning pump 1 and the cleaning effect. The output end of the standby cleaning pump 2 is fixedly connected with a circulating tank connecting pump inlet valve 16. The circulating tank connecting pump inlet valve 16 is installed at the output end of the standby cleaning pump 2 and is used to control the flow rate of the cleaning liquid flowing from the chemical cleaning circulating tank 19 to the standby cleaning pump 2. When the cleaning pump 1 fails or needs maintenance, the output end of the standby cleaning pump 2 is fixedly connected with a chemical cleaning circulating tank 19.

The outside of the system chemical cleaning return main pipe 12 is fixedly connected with a chemical cleaning return waste liquid valve 18. The right side of the system chemical cleaning return main pipe 12 is fixedly connected with a waste liquid tank 20. The waste liquid tank 20 is a device for storing the waste liquid generated during the chemical cleaning process. The design of the waste liquid tank 20 should consider factors such as the capacity of the waste liquid, the discharge method, and environmental protection requirements. The right side of the steam pipe 22 is fixedly connected with an MVR 21, which is a highly efficient evaporation and concentration device. The rear side of the MVR 21 is fixedly connected with a concentrated waste pipe 23.

[0037] Working principle: After the temporary system at the construction site is connected according to the cleaning plan, open the desalted water inlet valve 28, fill the chemical cleaning circulation tank 19 with water, start the cleaning pump 1, slowly open the pump outlet regulating valve 6, and adjust the opening degree of the pump outlet regulating valve 6 according to the value of the flow meter 5 to meet the requirements of the cleaning plan. When starting the cleaning pump 1, open the desalted water inlet valve 28, adjust the opening degree to keep the liquid level in the chemical cleaning circulation tank 19 balanced, continue to inject water into the system until the chemical cleaning return main pipe 12 of the system returns water through the filter 13 at the same time. At this time, the water is the system flushing water. Open the flushing water discharge valve 17 to discharge it to the discharge port 34 until the discharged water is clear and free of impurities. While closing the flushing water discharge valve 17, open the return to circulation tank valve 14. After observing that the liquid level of the chemical cleaning circulation tank 19 remains balanced, close the desalted water inlet valve 28. At this time, it enters the circulating heating stage. In the dosing stage, ignite the fuel steam generator 9, generate steam, supply steam to the heater 8 through the steam generator heater valve 10, and discharge the steam condensate through the steam condensate discharge pipe 32 to the discharge port 34. When the cleaning circulating liquid is heated to the temperature of the cleaning process, open the Venturi injection supply valve 30, add chemical drugs through the Venturi dosing device 29, and then transport them to the chemical cleaning circulation tank 19 through the pipeline 31 from the Venturi dosing device 29 to the circulation tank. After the dosing is completed and the temperature meets the process requirements, close the return to circulation tank valve 14, and at the same time open the return pump inlet valve 15. At this time, the chemical cleaning enters the closed-loop circulation stage until the chemical cleaning is completed. During the entire chemical cleaning stage, the slag filtered by the filter 13 should be cleaned in time. After the chemical cleaning is completed, stop the cleaning pump 1, stop the fuel steam generator 9, close the heater valve 10 of the fuel steam generator 9, close the return pump inlet valve 15, open the chemical cleaning return waste liquid valve 18, and drain the chemical cleaning liquid in the system completely.

[0038] Start the fuel steam generator 9, open the connection from the fuel steam generator 9 to the steam condensate discharge pipe 32. When the temperature rises to the evaporation temperature, open the liquid supply pump valve 26 to supply liquid to the MVR 21. The waste liquid is repeatedly concentrated by the MVR 21, the condensed water is discharged into the condensate pool 27, and the concentrated liquid is transported to the coal yard for combustion treatment through the concentrated waste pipe 23 in cooperation with the concentrated waste conveyor 24.
