DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings and examples.

[0016] Refer to the attached Figure 1-3 , a quick cleaning device for a compressor inlet filter, comprising a gas pipeline and a filter installed on the gas pipeline, the filter comprising a filter top cover 3, a filter cylinder 4 and a filter screen 9 in the filter cylinder 4, the composition also includes a cleaning motor 1, a rotating shaft 2, a cleaning frame 7, a brush 8, a spray disc 12, a spray disc fixing bracket 13 and a spray hole 14, the cleaning frame 7 is arranged in the filter screen 9, the cleaning frame 7 is provided with a brush 8 that matches the filter screen 9, the cleaning frame 7 is fixed on the rotating shaft 2, and the cleaning motor 1 is driven and connected to the rotating shaft 2; the spray disc 12 is fixed to the filter top cover 3 through the spray disc fixing bracket 13, and the spray disc 12 is provided with a spray hole 14 facing the filter screen 9.

[0017] In this embodiment, a quick cleaning device for a compressor inlet filter includes a cleaning motor 1, a rotating shaft 2, a filter top cover 3, a filter cylinder 4, a filter inlet gas pipe 5, a filter outlet gas pipe 6, a cleaning frame 7, a brush 8, a filter screen 9, a filter drain port 10, a hot water inlet pipe 11, a spray disc 12, a spray disc fixing bracket 13, and a spray hole 14, wherein:

[0018] The cleaning frame 7 is a rectangular frame, the size of which matches the diameter of the filter screen 9 .

[0019] The brush 8 on the cleaning frame 7 is heat-resistant, corrosion-resistant, and highly flexible. It's not made of metal, preventing wear on the filter screen during cleaning. The radial length of the brush 8 can be 2 cm greater than the gap between the rectangular frame 7 and the filter screen 9. If the radial length of the brush 8 is too long, it can cause the brush to sag, reducing cleaning effectiveness. If the radial length of the brush 8 is too short, the brush can't reach the filter screen 9, reducing cleaning effectiveness.

[0020] The diameter of the spray plate 12 pipe should not be greater than 20 mm. If the diameter of the filter hot water spray plate 12 pipe is greater than 20 mm, the diameter of the filter drain port 10 will need to be increased. The diameter of the filter drain port 10 should be greater than 80 mm.

[0021] The spray holes 14 on the spray disc 12 include a spray hole with a diameter of 5 mm directly below and two spray holes with a diameter of 5 mm at 30 degrees on both sides.

[0022] The pressure of the hot water in the hot water inlet pipe 11 is preferably greater than 0.5 MPa. If the pressure is too low, the spraying effect is poor. If the pressure is too high, the diameter of the filter drain port 10 needs to be increased.

[0023] The hot water sprayed from the spraying plate 12 is preferably ammonia water with a temperature of ≥75° C., or a solution that can dissolve impurities such as tar and naphthalene.

[0024] The hot water can be discharged to the container through the filter drain port 10 and recycled.

[0025] The method of using the utility model is as follows:

[0026] a. Coke oven gas enters the filter from the inlet gas pipe 5, passes through the filter screen 9, and enters the filter outlet gas pipe 6;

[0027] b. When impurities such as tar and naphthalene are attached to the filter screen 9, causing the pressure difference between the filter inlet gas pipe 5 and the filter outlet gas pipe 6 to be greater than 4.0 kPa, close the filter front and rear hand valves;

[0028] c. First open the filter hot water inlet pipe 11, so that hot water enters the filter, forming a spraying state;

[0029] d. Start the cleaning motor 1, drive the cleaning frame 7 and the brush 8 to rotate together in the filter;

[0030] e. tar, naphthalene and other impurities attached to the filter screen 9 are cleaned by washing with a brush 8 and spraying with hot water;

[0031] f. The hot water containing impurities such as tar and naphthalene is discharged from the filter drain port 10 at the bottom of the filter.
