Coking on the inner wall reduces the heating efficiency of the heating equipment and affects the safe operation of the equipment, so it needs to be cleaned regularly.
[0003] At present, high-pressure flushing equipment is usually used to flush the inner wall of the heating equipment. When the high-pressure flushing equipment is used for cleaning, a large amount of cleaning water and washed material residues are stored at the bottom of the heating equipment. When these mixtures are discharged through the material pipeline supporting the heating equipment, the material pipeline of the equipment is easily blocked.

[0012] The above technical solution has the following beneficial effects:
[0013] 1. The high-pressure cleaning device for heating equipment includes a heating equipment shell and a high-pressure cleaning head. A discharge pipeline is arranged at the bottom of the heating equipment shell. The water inlet of the high-pressure cleaning head is connected to a high-pressure water source. The heating equipment shell is used to provide a space for heating materials. The high-pressure cleaning head is used to spray high-pressure water to flush the coke on the inner wall of the heating equipment shell. It also includes a slag-water separator and a head. The slag-water separator is used to separate the discharged slag-water mixture, filter out the flushing water, and intercept the coke blocks. A slag discharge port is arranged at the bottom of the heating equipment shell, and the slag discharge port deviates from the discharge pipeline to avoid interference. A connecting pipe is fixedly arranged on the shell of the heating equipment, corresponding to the slag discharge port. The inner diameter of the connecting pipe is adapted to the diameter of the slag discharge port, and a threaded section is arranged on the inner wall of the connecting pipe. The end cap is threadedly fitted in the connecting pipe to form a detachable connection. Under normal circumstances, the end cap is assembled in the connecting pipe to seal the shell of the heating equipment, thereby ensuring that the shell of the heating equipment heats the material normally and avoiding material leakage. When the shell of the heating equipment needs to be decoked, the end cap is removed, and the discharge pipeline matching the shell of the heating equipment is closed. The inner wall of the shell of the heating equipment is flushed with a high-pressure cleaning head to discharge the slag-water mixture formed by flushing from the slag discharge port at the bottom. The slag-water separator includes a connecting sleeve and a filter screen. The connecting sleeve and the filter screen are connected by a flexible pipe. The outer wall of the connecting sleeve is provided with a threaded section, and the connecting sleeve is detachably connected to the connecting pipe of the heating equipment shell through threaded matching. Under normal circumstances, the connecting sleeve is separated from the connecting pipe. When decoking, after the head is disassembled, the connecting sleeve is threadedly installed on the connecting pipe. The slag-water mixture is discharged through the slag discharge port and discharged into the filter screen by the flexible pipe. The coke blocks therein are intercepted and the water is filtered out, completing the purpose of cleaning the heating equipment shell and preventing the coke blocks from polluting the factory area. After cleaning, the connecting sleeve is disassembled and the head is assembled, and normal heating operations can be carried out.
[0014] 2. The top surface of the head and the slag discharge port are adapted to the shape of the inner wall of the heating equipment shell. A turntable is fixed on the bottom surface of the head to facilitate the installation and removal of the head by the staff, and to ensure the smoothness between the head and the inner wall of the heating equipment shell, thereby reducing the risk of material accumulation at the slag discharge port.
[0015] 3. One end of the flexible pipe is wrapped around the connecting sleeve and fixed by a cable tie, and the other end of the flexible pipe is wrapped around the filter and fixed by a cable tie, so as to ensure the connection stability between the flexible pipe, the connecting sleeve and the filter, and facilitate the installation, disassembly and replacement of the flexible pipe.

DETAILED DESCRIPTION
[0021] See also Figures 1 to 3 , is a specific embodiment of a high-pressure cleaning device for heating equipment. The high-pressure cleaning device for heating equipment includes a heating equipment shell 1 and a high-pressure cleaning head 2. In this embodiment, the heating equipment shell is an upright tank body and is provided with a heating interlayer. The high-pressure cleaning head is a conventional high-pressure cleaning tool on the market. A discharge pipeline 3 is arranged at the bottom of the heating equipment shell 1. Obviously, a valve is arranged on the discharge pipeline. The water inlet end of the high-pressure cleaning head 2 is connected to a high-pressure water source. It also includes a slag-water separator 4 and a head 5. A slag discharge port 6 is arranged at the bottom of the heating equipment shell 1. The slag discharge port 6 deviates from the discharge pipeline 3. Usually, the slag discharge port is arranged as a circular hole. A connecting pipe 7 is fixedly arranged on the heating equipment shell 1. Corresponding to the slag discharge port 6, the inner diameter of the connecting pipe 7 is adapted to the caliber of the slag discharge port 6, and a threaded section is arranged on the inner wall of the connecting pipe 7. In this embodiment, the connecting pipe is fixed to the outer wall of the heating equipment shell 1 by welding. The end cap 5 is threadedly engaged in the connecting pipe 7 to form a detachable connection. In order to avoid material accumulation at the slag discharge port, the top surface of the end cap is adapted to the shape of the inner wall of the heating device shell corresponding to the slag discharge port. Specifically in this embodiment, the top surface of the end cap is designed as an outwardly concave arc surface, which is adapted to the shape of the eccentric inner wall at the bottom of the vertical tank. A turntable is fixedly arranged on the bottom surface of the end cap to facilitate manual rotation of the end cap, which is conducive to the installation and removal of the end cap. The slag-water separator 4 includes a connecting sleeve 8 and a filter screen 9. The connecting sleeve 8 and the filter screen 9 are connected by a flexible pipe 10. Specifically, the flexible pipe 10 is a corrugated pipe, and the filter screen is a stainless steel filter screen. One end of the flexible pipe 10 is wrapped on the connecting sleeve 8 and fixed by a cable tie, and the other end of the flexible pipe 10 is wrapped on the filter screen 9 and fixed by a cable tie. The outer wall of the connecting sleeve 8 is provided with a threaded section, and is detachably connected to the connecting pipe 7 of the heating device shell by threaded engagement.
[0022] The working principle of the utility model is as follows: under normal circumstances, the head thread is matched on the connecting pipe, and the top surface of the head and the inner wall of the shell of the heating equipment are smoothly transitioned, and the heating equipment heats the material. When the heating equipment runs for a period of time and the coking on the inner wall of the shell reaches a certain degree, the heating and feeding are stopped, and after the material is discharged through the discharge pipeline, the discharge pipeline is closed, the head is disassembled, and the connecting sleeve thread is matched on the connecting pipe. The inner wall of the shell of the heating equipment is flushed with a high-pressure cleaning head to flush the coking off the inner wall. The coking mixed water enters the filter screen from the slag discharge port through the connecting pipe, the connecting sleeve, and the flexible pipe. The coking therein is trapped and the water flows out, completing the cleaning and avoiding environmental pollution. After the cleaning is completed, the connecting sleeve is disassembled and the head is assembled.
