Integrated compressed air filtering and purifying apparatus and filtering and purifying method thereof

Abstract

The invention discloses an integrated compressed air filtering and purifying apparatus and a filtering and purifying method thereof. The integrated compressed air filtering and purifying apparatus comprises a filtering cover body and a filtering base, wherein the filtering cover body and the filtering base are fixedly connected to form a filtering body, a filtering chamber is arranged in the filtering body, a filtering core is arranged in the filtering cover body, a flow guide device matched with the filtering core in a sealed manner is arranged in the filtering base, an air inlet for flowingcompressed air into the flow guide device is arranged on the first side wall of the filtering base, a gas discharge port is arranged on the top portion of the filtering cover body, and a first-stage water discharge valve and a second-stage water discharge valve are respectively arranged on the second side wall of the filtering base. The method is applied to the apparatus. According to the invention, the apparatus has advantages of simple structure, convenient use, high purification efficiency, powerful pollution discharge function, long service life, small installation space, convenient maintenance, low power consumption, low cost and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of air purification, in particular to an integrated compressed air filtration and purification device and a filtration and purification method applied to the device. 【Background technique】 [0002] Compressed air is the second largest power source next to electricity and is widely used in various fields of industrial production. Unpurified compressed air contains a considerable amount of impurities, mainly: moisture, oil and solid particles. The amount of impurities determines the quality of compressed air. Different applications have different requirements for compressed air quality. The use of filters to filter out solid particles, oil and some moisture in compressed air is the main link in the compressed air purification process. [0003] The quality of compressed air is clearly classified in the ISO8573-1 "Compressed Air Part 1: Impurities and Purity Grades" standard. In different applications, diffe...

AI Technical Summary

Problems solved by technology

The main problems and disadvantages of this scheme are: the sewage in the system cannot be discharged in time, and it may freeze in winter in cold regions and cannot be discharged; the diameter of the drain is generally small, and it is easy to be blocked by dirt, thereby affecting the drainage function; frequent cleaning is required Maintenance, increased workload; service life is not long

The main problems and disadvantages of this scheme are: the user must provide a power supply, otherwise it cannot be used, and the application occasions are limited; the sewage cannot be discharged in time, and it may freeze in winter in cold areas and cannot be discharged; the opening time of the solenoid valve is related to the filter There is no definite quantitative relationship between the amount of accumulated water in the system, which often causes the system to drain the accumulated water uncleanly or empty and waste compressed air; the coil of the solenoid valve and the sealing rubber diaphragm inside the valve are easily damaged and the service life is not long

This solution still has the following main problems and shortcomings: the user must provide a power supply, otherwise it cannot be used, and the application occasions are limited; the sewage cannot be discharged in time, and it may freeze in winter in cold regions and cannot be drained; the solenoid valve coil and the sealing rubber in the valve The diaphragm is easily damaged and has a short service life; the structure is complicated, the cost is high, and the maintenance is inconvenient, so it is difficult to popularize and use
