Description

Technical Field

[0001] The utility model relates to a compressor filter quick cleaning device, belonging to the technical field of compressor inlet protection equipment in the petrochemical industry. Background Art

[0002] In the petrochemical industry, compressors are generally used. Filters are installed at the inlet of the compressor, and their main function is to filter impurities in the medium. The filter consists of a filter cover, a filter cylinder, and a filter screen. After the filter has been used for a period of time, tar, naphthalene, etc. will adhere to the filter screen, causing the differential pressure between the gas pipeline at the filter inlet and the gas pipeline at the filter outlet to increase. When the pressure difference is greater than 4.0 kPa, the filter screen needs to be cleaned. The traditional cleaning method takes up to 72 hours, and the cleaning efficiency is low, which affects the normal use of the compressor. Utility Model Content

[0003] The utility model aims to provide a compressor filter quick cleaning device with short cleaning time and high efficiency, so as to solve the problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] A compressor filter quick cleaning device comprises an agitator motor, a speed reducer, an agitator shaft, a support, a filter top cover, a filter cylinder, a filter outlet gas pipeline, a filter inlet gas pipeline, agitator blades, a filter screen, a steam cleaning port and a sewage outlet. The filter cylinder is provided with a filter top cover on the top, a sewage outlet is provided at the bottom of the filter cylinder, a filter outlet gas pipeline and a filter inlet gas pipeline arranged oppositely are provided on both sides of the filter cylinder, valves are installed on the filter outlet gas pipeline and the filter inlet gas pipeline, and a steam cleaning port is also provided on the filter outlet gas pipeline; the agitator motor is fixed to the filter top cover through a support, the agitator motor is connected to the agitator shaft through a speed reducer, the agitator shaft is arranged concentrically with the filter cylinder, agitator blades are provided on the agitator shaft, and the agitator blades and the center lines of the filter outlet gas pipeline and the filter inlet gas pipeline are on the same horizontal plane.

[0006] There are two agitator blades on the agitator shaft, and the two agitator blades are on the same straight line.

[0007] The length of the agitator blade is smaller than the diameter of the filter cylinder, and the thickness of the agitator blade is smaller than or equal to the diameter of the filter outlet gas pipeline and the filter inlet gas pipeline.

[0008] The agitator blades are fixed on the shaft sleeve, and the shaft sleeve is fixed on the agitator shaft through the shaft sleeve pin.

[0009] A sealing structure is provided between the agitator shaft and the filter top cover.

[0010] By adopting the utility model, when it is necessary to clean the filter, the front and rear manual valves of the filter are closed, the steam cleaning port of the filter is opened, and the agitator motor is started at the same time, and the steam in the filter is stirred by the agitator blades to form a vortex in the steam in the filter. The steam forming the vortex quickly blows away impurities such as tar and naphthalene attached to the filter screen.

[0011] The beneficial effect of the utility model is that the cleaning time of the filter is reduced from 72 hours in the background technology to 3 hours, which greatly improves the cleaning efficiency and ensures the normal use of the compressor. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the figure: agitator motor 1, reducer 2, coupling 3, agitator shaft 4, support 5, sealing structure 6, filter top cover 7, filter cylinder 8, filter outlet gas pipeline 9, filter inlet gas pipeline 10, agitator blade 11, filter screen 12, filter steam cleaning port 13, sewage outlet 14, shaft sleeve 15, shaft sleeve pin 16. DETAILED DESCRIPTION

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

[0016] Refer to the attached Figure 1 , 2 A compressor filter quick cleaning device comprises a stirrer motor 1, a reducer 2, a stirrer shaft 3, a support 5, a filter top cover 7, a filter cylinder 8, a filter outlet gas pipeline 9, a filter inlet gas pipeline 10, a stirrer blade 11, a filter screen 12, a steam cleaning port 13 and a sewage outlet 14. The filter cylinder 8 is provided with a filter top cover 7 on the top, a sewage outlet 14 on the bottom of the filter cylinder 8, and a filter outlet gas pipeline 9 and a filter inlet gas pipeline arranged oppositely on both sides of the filter cylinder 8. 10. Valves are installed on the filter outlet gas pipeline 9 and the filter inlet gas pipeline 10. The filter outlet gas pipeline 9 is also provided with a steam cleaning port 13. The agitator motor 1 is fixed to the filter top cover 7 through the support 5. The agitator motor 1 is driven and connected to the agitator shaft 3 through the reducer 2. The agitator shaft 3 is concentrically arranged with the filter cylinder 8. The agitator shaft 3 is provided with agitator blades 11. The agitator blades 11 are on the same horizontal plane as the center lines of the filter outlet gas pipeline 9 and the filter inlet gas pipeline 10.

[0017] In this embodiment, refer to the attached Figure 1 , 2 The agitator blade 11 is made of corrosion-resistant 306 stainless steel or fiberglass, with a length less than the diameter of the filter cylinder 8 and a thickness less than or equal to the diameter of the filter outlet gas pipe 9 and the filter inlet gas pipe 10. There are two agitator blades. When there are more than two, the resistance of the gas passing through the filter will increase when the filter is operating normally. When there is only one agitator shaft 4, it will be unbalanced and vibrate greatly.

[0018] The agitator blade 11 is fixed on a sleeve 15 , and the sleeve 15 is fixed on the agitator shaft 3 via a sleeve pin 16 .

[0019] Coke oven gas enters from the filter inlet gas pipeline 10, passes through the filter screen 12, and reaches the filter outlet gas pipeline 9. When tar, naphthalene and other components are attached to the filter screen 12, resulting in a pressure difference between the filter inlet gas pipeline 10 and the filter outlet gas pipeline 9 greater than 4.0 kPa, follow the steps below:

[0020] (1) Close the front and rear manual valves of the filter, open the steam cleaning port 13 of the filter, and allow steam to enter;

[0021] (2) Start the agitator motor 1, driving the reducer 2 and the coupling 3, the agitator shaft 4 and the agitator blade 11 to rotate;

[0022] (3) using the agitator blade 11 to stir the steam in the filter so that the steam in the filter forms a vortex;

[0023] (4) The vortex-forming steam quickly blows away the impurities such as tar and naphthalene attached to the filter screen 12. When the pressure decreases, the steam is replenished from the filter steam cleaning port 13 to replenish the pressure.
