Description

Technical Field

[0001] This utility model relates to the field of gas compression technology, and in particular to a gas compression and purification processing system. Background Technology

[0002] A compressed air generator is a device that compresses air (or other gases) using a compressor and stores the compressed air in a storage tank. It mainly consists of a compressor, a storage tank, and a filter. Existing compressed air generators have a loose structure and large size, making them unsuitable for use in small workshops with limited space. Although manufacturers have modified them to suit small workshop environments, existing devices still suffer from incomplete removal of moisture and impurities during compressed air production, affecting their performance. Utility Model Content

[0003] The purpose of this invention is to provide a gas compression and purification system to solve the problems encountered in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A gas compression and purification system includes a compressor, a first filter, a dryer, a gas storage tank, a second filter, and a gas manifold. The pipeline at the output end of the compressor is connected to the first filter via a first check valve. The output end of the first filter is connected to the dryer. The dryer is connected to the gas storage tank via a second check valve. The output end of the gas storage tank is connected to the second filter via a valve. The output end of the second filter is connected to the gas manifold.

[0006] In the above scheme, the first filter is a backwash filter, and the second filter is a chemical air filter. As a preferred embodiment, at least two first filters are provided, and their bottom pipes are connected in parallel and then connected to a water storage tank via a drain solenoid valve.

[0007] In the above scheme, a buffer tank and a cooling coil are sequentially installed on the pipeline at the output end of the compressor, and the cooling coil is connected to the first filter through a first one-way valve. As a preferred embodiment, a pressure relief valve is installed on the outside of the buffer tank.

[0008] In the above scheme, a pressure gauge is installed on the top of the gas storage tank, and the pressure gauge is connected to the compressor via a pressure switch and a pressure sensor.

[0009] In the above scheme, the output end of the gas storage tank is connected to a pressure reducing valve via a valve, and the output pipeline of the pressure reducing valve is connected to the second filter. As a preferred embodiment, a dew point meter is installed on the pipeline between the pressure reducing valve and the second filter, and a dew point temperature display is installed on the outside of the dew point meter.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by setting two filtration stages, the compressed gas first passes through the first filter and is stored in the gas storage tank. Later, when preparing to supply gas, it passes through the second filter and is finally delivered to the gas manifold to wait for gas supply. This two-stage filtration can remove moisture and impurities more efficiently, thereby purifying the compressed gas and improving its purity. Attached Figure Description

These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0015] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0016] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, a gas compression and purification system includes a compressor 1, a first filter 6, a dryer 9, a gas storage tank 11, a second filter 18, and a gas manifold 19.

[0018] The output pipe of compressor 1 is connected to the first filter 6 via the first one-way valve 5. In specific implementation, a buffer tank 2 and a cooling coil 4 are installed sequentially on the output pipe of compressor 1. The cooling coil 4 is then connected to the first filter 6 via the first one-way valve 5. The buffer tank 2 is used to buffer the compressed gas output from compressor 1, and the cooling coil 4 is used to cool the gas. As a preferred embodiment, a pressure relief valve 3 is installed on the outside of the buffer tank 2 for venting.

[0019] The output of the first filter 6 is connected to the dryer 9. The first filter 6 is a backwash filter, which filters impurities from the compressed gas by passing the compressed gas through the water in the backwash filter and venting the gas. The first filter 6 can also be equipped with a filter plate with multiple layers of filter screens to filter the compressed gas. As a preferred embodiment, at least two first filters 6 are provided, and their bottom pipes are connected in parallel and then connected to a water storage tank 8 through a drain solenoid valve 7. During the filtration process, water containing impurities is discharged into the water storage tank 8.

[0020] In addition, the first filter 6 can also use the pressure swing adsorption principle to remove water and hydrocarbons from the gas. The main process is as follows: Compressed air enters the adsorption tower, where hydrocarbons and water are selectively adsorbed under high pressure; when the intake stops, the pressure in the adsorption tower drops, the adsorbed impurities are released and discharged, and the purified gas enters the dryer. Purified gas is continuously output by alternating pressurization and depressurization of the two towers.

[0021] Dryer 9 is connected to air tank 11 via second check valve 10. The output of air tank 11 is connected to second filter 18 via valve 14. Second filter 18 is a chemical air filter used to filter out impurities such as water and carbon dioxide from compressed gas using activated carbon and molecular sieves. Finally, the output of second filter 18 is connected to gas manifold 19, which concentrates the compressed gas supplied from individual gas consumption points to achieve centralized gas supply.

[0022] Since the second filter 18 uses chemical filtration to remove chemical substances from the gas, conventional room temperature catalytic technology can be used in its implementation to further remove water, carbon dioxide and non-methane chemicals from the gas through a combination of physical adsorption and chemical reaction.

[0023] In this system, by setting up two filtration stages, the compressed gas first passes through the first filter 6 and is stored in the gas storage tank 11. Later, when preparing to supply gas, it passes through the second filter 18 and is finally delivered to the gas manifold 19 to wait for gas supply. This two-stage filtration can remove moisture and impurities more efficiently and improve the purity of the compressed gas.

[0024] In the above scheme, a pressure gauge 12 is installed on the top of the gas storage tank 11. The pressure gauge 12 is connected to the compressor 1 via a pressure switch 13 and a pressure sensor. Because the existing device lacks an intelligent control mechanism, it cannot automatically adjust its operating status based on the content of compressed gas in the gas storage tank, requiring manual monitoring and operation to start and stop the equipment. In implementation, a threshold is set for the pressure sensor; once reached, an alarm is triggered to notify the backend. The backend then controls the compressor 1 to start automatically based on the set start conditions. This system, through the pressure switch 13 and pressure sensor, can monitor the compressed gas content in the gas storage tank 11 in real time and control the operation of the compressor 1 based on the content.

[0025] In the above scheme, the output end of the gas storage tank 11 is connected to a pressure reducing valve 15 via a valve 14, and the output pipeline of the pressure reducing valve 15 is connected to the second filter 18. As a preferred embodiment, a dew point meter 16 is installed on the pipeline between the pressure reducing valve 15 and the second filter 18 to measure the water content in the gas. A dew point temperature display 17 is installed on the outside of the dew point meter 16 to directly display the water content and determine whether the compressed gas meets the standard.

[0026] The workflow of this system during implementation is as follows:

[0027] Air is compressed by compressor 1 and enters the system. It is buffered by buffer tank 2, and the water produced is periodically discharged through the lower drain valve 3. The air then enters the cooling coil 4 through a pipeline for cooling and to promote condensation. It then passes through the first check valve 5 and enters the first filter 6 for water and dust removal. The removed water is periodically discharged into the water storage tank 8 through the drain solenoid valve 7. Subsequently, the compressed air enters the dryer 9 for further dehydration. The dried compressed air then enters the air storage tank 11 through the second check valve 10.

[0028] The upper part of the gas storage tank 11 includes a mechanical pressure gauge 12 and an electronic pressure display or pressure sensor, which is connected to the compressor 1 via a pressure switch 13. When the compressed gas in the gas storage tank 11 is insufficient, the electrical signal controls the compressor 1 to start the gas extraction device, and when there is enough compressed gas, it controls the compressor 1 to stop running.

[0029] When in use, first turn on the gas tank 11 switch. Compressed gas enters the pressure reducing valve 15 through the valve 14. The pressure is reduced and stabilized by the pressure reducing valve 15. Then, the dryness is monitored in real time by the dew point meter 16, and the relevant moisture content data is displayed on the dew point temperature display 17. Finally, after further removal of pollutants such as H2O, CO2, and NMHC (non-methane total hydrocarbons) by the second filter 18, it is output for use through the gas manifold 19.
