Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air compressor dryers, in particular to an anti-pollution and noise reduction device for an air compressor dryer discharge port. Background Art
[0002] An air compressor dryer is a device that combines an air compressor and a dryer. Its operating process is as follows: the air compressor stores compressed air in a storage bag, which is then dehydrated in a refrigerated dryer. The air then passes through a secondary filter element, leaving the compressed air with a very low moisture content. The air then enters the dryer for adsorption and is then fed into the compressed air network for use. The dryer's adsorbent, after absorbing excess moisture and oil vapor, must be discharged regularly. Therefore, the dryer has a discharge port, which requires an anti-pollution and noise reduction device.
[0003] At present, the traditional anti-pollution and noise reduction device for the exhaust port of the air compressor dryer is a squirrel cage wire mesh cover. The head of the cage wire mesh cover is sealed with iron sheets facing the exhaust port to prevent the water-containing gas from directly rushing towards other surrounding objects or people. Its disadvantages are as follows: when the water-containing compressed air is discharged, the pressure is as high as 0.6-1.0MPa, and the noise is as high as 120 decibels or more, and it is irregular, seriously affecting the health of people around the equipment. The noise travels a long distance and is harsh even from more than 100 meters away, which puts great pressure on environmental protection. In addition, the oil and water splash directly into the environment, making it difficult to collect. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an anti-pollution and noise reduction device for the discharge port of an air compressor dryer. The noise reduction device is more environmentally friendly and has simple oil and water collection.
[0005] To solve the above problems, the following technical solutions are provided:
[0006] The present invention features an anti-fouling and noise reduction device for the exhaust port of an air compressor dryer. It comprises a water-gas separator and a cylindrical housing. An oil filter is concentrically disposed within the housing. The inlet of the oil filter corresponds to the outer end of the housing, with a gap between the inlet and the inner sidewall of the outer end. The outlet of the oil filter forms a fixed, sealed fit with the inner end surface of the housing's bottom. A clearance hole is provided in the bottom of the housing corresponding to the outlet of the oil filter. The outlet of the oil filter is connected to the inlet of the water-gas separator via a pipeline.
[0007] Wherein, the outer side wall of the shell is covered with a sound-absorbing cotton layer.
[0008] An annular flange is concentrically fixed on the outer side wall of the barrel opening of the shell.
[0009] The steam-water separator includes a three-dimensionally arranged tank body, the lower part of the tank body is conical, and the end with a smaller diameter of the lower part of the tank body faces downward, and there is a water outlet at the bottom of the tank body; the inlet of the steam-water separator is located at the upper part of the tank body, and an air outlet is provided on one side of the upper part of the tank body corresponding to the inlet of the steam-water separator; a baffle is provided in the upper part of the tank body, and the four sides of the baffle are fixedly sealed with the inner wall of the tank body, the inlet of the steam-water separator is located below the baffle, and the air outlet is located above the baffle; a central tube is concentrically arranged in the upper part of the tank body, and a clearance port is provided on the baffle corresponding to the upper end of the central tube, the upper end of the central tube is in the clearance port, and the central tube and the clearance port are fixedly sealed.
[0010] The baffle is arranged as a whole to be inclined downward.
[0011] The above solution has the following advantages:
[0012] The air compressor dryer discharge port anti-pollution and noise reduction device of the present invention has an oil filter core concentrically disposed within the housing. The inlet end of the oil filter core corresponds to the barrel end of the housing, and there is a gap between the inlet end of the oil filter core and the inner side wall of the barrel end of the housing. The outlet end of the oil filter core is fixedly sealed with the inner end surface of the barrel bottom of the housing. The barrel bottom of the housing corresponding to the outlet of the oil filter core has a clearance hole, and the outlet of the oil filter core is connected to the inlet of the pipeline water separator. The noise reduction device uses the oil filter core to filter oil pollution. Moreover, when high-pressure air enters the oil filter core, its volume suddenly increases, thereby reducing the air pressure and flow rate. At the same time, when the air passes through the filter paper and porous mesh of the oil filter core, the pressure is further reduced, thereby reducing the noise generated when the compressed air is discharged. Furthermore, the oil filter core and the water separator are used to collect sewage and oil pollution, thereby preventing the oil and water from being directly discharged into the environment, making collection convenient.

[0017] The present invention will be described in further detail below with reference to the accompanying drawings.
[0018] like Figure 1 and Figure 2 As shown, the anti-pollution and noise reduction device for the exhaust port of an air compressor dryer of the present invention includes a steam-water separator and a cylindrical shell 2. An annular flange 1 is concentrically fixed on the outer wall of the barrel mouth of the shell 2 so that the entire device can be docked and fixedly connected to the exhaust port of the air compressor dryer. The outer wall of the shell 2 is covered with a sound-absorbing cotton layer 7 to further reduce noise emissions.
[0019] like Figure 2 As shown, an oil filter is concentrically mounted within the housing 2. The inlet of the oil filter corresponds to the barrel end of the housing 2, with a gap between the inlet and the inner sidewall of the barrel end. The outlet of the oil filter forms a fixed, sealed fit with the inner end surface of the barrel bottom of the housing 2. A clearance hole is provided in the barrel bottom of the housing 2, corresponding to the outlet of the oil filter. The outlet of the oil filter is connected to the inlet of the steam-water separator via a pipeline.
[0020] In this embodiment, as Figure 2 Shown and Figure 4 As shown, the oil filter element includes a tubular filter screen 9, which is enclosed by a filter paper cartridge 10. One end of the filter paper cartridge 10 has a first sealing cap 8, which is fixedly and sealedly connected to the ends of the filter paper cartridge 10 and the filter screen 9. The first sealing cap 8 serves as the inlet of the oil filter element. The other end of the filter paper cartridge 10 has a second sealing cap 11, which is fixedly and sealedly connected to the ends of the filter paper cartridge 10 and the filter screen 9. The second sealing cap 11 has a center hole, from which a short circular tube 3 extends outward, serving as the outlet of the oil filter element. The filter paper cartridge 10 is used to filter oil contaminants. The specific materials used are known in the art and will not be described in detail here.
[0021] like Figure 3 As shown, the steam-water separator includes a three-dimensionally arranged tank body 4. The lower portion of the tank body 4 is conical, with the smaller end of the lower portion facing downward. A water outlet 6 is located at the bottom of the tank body 4. The steam-water separator inlet is located at the upper portion of the tank body 4, and an air outlet 5 is located on one side of the upper portion of the tank body 4 corresponding to the steam-water separator inlet. A baffle 12 is located within the upper portion of the tank body 4, and the periphery of the baffle 12 is fixedly sealed with the inner wall of the tank body 4. The steam-water separator inlet is located below the baffle 12, and the air outlet 5 is located above the baffle 12. A central tube 13 is concentrically arranged within the upper portion of the tank body 4. A clearance opening is provided on the baffle 12 corresponding to the upper end of the central tube 13. The upper end of the central tube 13 is connected to the clearance opening, and the central tube 13 and the clearance opening are fixedly and sealed. The baffle 12 is arranged as a whole, tilted downward, to prevent the accumulation of sewage.
[0022] During use, the discharged high-pressure gas enters from the barrel mouth of the shell. Under the action of the first sealing cover 8, the high-pressure gas enters between the filter paper cylinder 10 and the inner side of the shell. The high-pressure gas passes through the filter paper cylinder 10 and the filter screen 9 and enters the inside of the oil filter element. In this process, the oil is collected. At the same time, the airflow enters a large volume, the flow rate slows down, the noise is reduced, and the airflow passing through the filter paper cylinder 10 and the filter screen 9 further reduces the noise; then, the airflow enters the steam-water separator through the pipeline. Under the action of the central tube 13 and the baffle 12, the airflow rotates downward. According to the cyclone separation principle, the sewage falls into the lower part of the tank body 4 and is discharged from the water outlet 6 under the action of weight. The airflow rises from the central tube 13 and is discharged from the air outlet 5.
[0023] This solution replaces the squirrel-cage wire mesh structure at the compressor dryer outlet with a 250mm x 20u oil filter and water-water separator. During discharge, compressed air containing oil and water first passes through the filter's interior space before being adsorbed by the filter's intermediate material and then enters the water-water separator. A wastewater collection tank is placed below the water separator's outlet (6), or it can be directly connected to the sewage network. After adsorption and regeneration, the discharged water, oil, and gas are concentrated in the filter's intermediate layer, while the wastewater is collected separately and the purified air is directly discharged. This solution also reduces noise during exhaust from the compressor dryer outlet, ensuring low-noise emissions of the oil and water gas discharged with the compressed air, fully meeting environmental requirements. This device offers not only extremely low cost, excellent noise reduction, and superior safety, but also high stability, requiring no special operation, and is extremely convenient, effectively meeting environmental requirements and requiring minimal investment, making it suitable for workshop renovations.
