AI Technical Summary
When the existing air compressor is used at the end, due to the presence of particulate matter such as high-iron rust, the impeller wears severely, dynamic balance fails, and maintenance costs are high, which affects the stable operation of the desulfurization system.
Two sets of dust removal T-level (E7-level) filters are added in parallel structure to filter the imported compressed air, reduce the impact of particulate matter on the compressor, and replace or clean the filter element in the filter without shutting down.
It effectively reduces the damage of the air booster impeller, reduces maintenance costs, ensures the stable operation of the closed environment, and reduces operating costs.

Abstract
Description
Technical Field
[0001] The invention relates to the field of compressors, and in particular to a device for reducing damage to an air boost impeller. Background Art
[0002] The fuel supply plant is located at the end of the compressed air pipeline network of Quannan Steel. The compressed air pressure used in the chemical product desulfurization system of the fuel supply plant is greatly affected by the upstream users. There are often situations such as insufficient pressure and pressure fluctuations, which make the desulfurization system unable to operate normally and cause the online environmental data to exceed the hydrogen sulfide standard. Considering the high cost of adding a new air compressor station and the factors that the upstream users cannot control, it is decided to install an air booster in the desulfurization system.
[0003] Due to the presence of high rust and other small particles at the end of the compressed air network, although a Y-type filter was added at the inlet of the air compressor, the effect was not obvious, the air compressor impeller was severely worn, and the compressed air was not increased, and the dynamic balance failed, and the internal gears and couplings were damaged to varying degrees. The original Y-type filter was not effective, and the compressor had to be stopped for maintenance and repair, and the maintenance cost was high. Since the supply of compressed air was stopped during maintenance, the stability of the desulfurization system operation could be affected at any time, causing the risk of exceeding environmental protection data.
[0004] Therefore, it is necessary to develop new devices to reduce the occurrence of air boost impeller damage. Summary of the invention

[0006] Technical solution: A device for reducing damage to an air boost impeller of the present invention is characterized in that two sets of filters are added in parallel to filter the inlet compressed air, thereby reducing the impact of particulate matter in the terminal compressed air on the compressor.
[0007] Wherein, the filter is a dust removal T grade, that is, an E7 grade filter.
[0008] Wherein, the compressor is connected with a compressed air pipeline.
[0009] Wherein, two sets of filters are arranged in parallel on the compressed air pipeline.
[0010] Wherein, the compressed air pipeline is provided with stop valves before and after the parallel bypass.
[0011] Wherein, the parallel bypass is provided with stop valves before and after the filter respectively.
[0012] The two sets of filters filter the compressed air and then mix them into the compressor.
[0013] Wherein, the compressed air pipeline is provided with inlet and outlet pressure gauges.
[0014] The filter removes particles larger than 1UM micron, and the residual oil content is 1PPM.
[0015] Among them, the initial pressure difference of the filter is 0.01MPa, the pressure difference of the filter element replacement is 0.07MPa, and the filter element replacement time is 4000h of the air compressor startup time.
[0016] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention provides a new type of device that is easy to implement and maintain, reduces impeller damage, reduces maintenance costs, ensures a closed environment, and operates reliably. Through the two parallel compressed air routes, the working filter device can be switched at any time, and the filter element in the filter device can be replaced or cleaned without stopping the machine, ensuring the online operation of the air compressor and the operating cost caused by downtime during maintenance. It has been calculated that it costs 520,000 yuan to repair a compressor, and the maintenance cost after installing this device is 7,000 yuan. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0020] The device for reducing damage to the air boost impeller of the present invention adopts a parallel structure to add two sets of filters 3 to filter the inlet compressed air and reduce the impact of the terminal compressed air particles on the compressor 4. Among them, the filter 3 is a dust removal T-level, that is, an E7-level filter. The compressor 4 is connected to the compressed air pipeline 1. Two sets of filters 3 are arranged in parallel on the compressed air pipeline 1. The compressed air pipeline 1 is provided with a stop valve 2 before and after the parallel bypass. The parallel bypass is provided with a stop valve 2 before and after the filter 3. The two sets of filters 3 filter the compressed air and mix them into the compressor 4. The compressed air pipeline 1 is provided with an inlet and outlet pressure gauge. The filter 3 removes particles larger than 1UM microns, and the residual oil content is 1PPM. The initial pressure difference of the filter 3 is 0.01MPa, the pressure difference of the filter element replacement is 0.07MPa, and the filter element replacement time is 4000h of the air compressor startup time.

Through the two parallel compressed air routes, the working filter device can be switched at any time, and the filter element in the filter device can be replaced or cleaned without stopping the machine, ensuring the online operation of the air compressor and the operating cost caused by the shutdown during maintenance. According to calculations, it costs 520,000 yuan to repair a compressor, and the maintenance cost after installing this device is 7,000 yuan.
