Description

Technical Field

[0001] The utility model belongs to the technical field of air compressors, and in particular relates to an integrated compressed air unit. Background Art

[0002] An air compressor is a device used to compress gas. Its structure is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. The market application of air compressors themselves is relatively mature. In addition, there are also a wide variety of back-end air cleanliness treatment equipment to meet the different needs of various industries. In special areas such as medical treatment where air quality is subject to mandatory regulations, customers need to match post-processing equipment according to various air compressors, and professional institutions are required to conduct inspections to determine whether the air quality meets the standards.

[0003] Existing air compressors are based on industry needs and use a large system consisting of a standard air compressor + refrigerated dryer (adsorption dryer) + air storage tank + filter to complete the task of obtaining high-quality compressed air. The existing technology cannot compress and purify the air multiple times. The temperature of the compressed air is too high to separate the oil and water in the compressed gas. It can only perform simple separation on the compressed air, and cannot remove the oil, water, bacteria and odor in the compressed air. Utility Model Content

[0007] Preferably, an emergency stop button is fixedly connected to the outer wall of the shell.

[0008] Preferably, a safety valve is provided on the side wall of the oil-gas separation barrel.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The air outlet of the compressor main engine is fixedly connected to the air inlet of the oil-gas separation barrel through a pipeline. The oil-gas separation barrel is provided with an oil-gas separator inside. The air outlet of the oil-gas separation barrel is fixedly connected to the air inlet of the oil filter and the radiator through pipelines. The return end of the compressor main engine is fixedly connected to the air outlet of the oil filter and the radiator through pipelines. The compressor main engine compresses the air, and the compressed oil-gas mixed gas enters the oil-gas separation barrel.

The air containing a small amount of lubricating oil (about 3-5PPM) after separation by the oil and gas separator enters the after-cooling part of the radiator through the minimum pressure valve for cooling. The cooled air enters the water removal filter for the first separation of water, oil and gas, and then enters the compressed air dryer to continue drying and separating a small amount of oil, thereby obtaining relatively dry compressed air, and then enters the first oil removal filter and the second oil removal filter for the main oil and gas separation work, and finally enters the sterilizing filter for intercepting microorganisms and odors, and finally obtains clean compressed air below 0.08PPM. As a high-quality compressed air application, the air that has been compressed and separated for multiple times is subjected to more stringent separation of water, oil and gas again, achieving the effect of sterilizing and deodorizing the compressed air, and finally obtaining clean compressed air below 0.08PPM, solving the problem that the compressed air obtained by simply separating the compressed air contains too much oil and water as well as bacteria and odor.
