Method for monitoring safe operation of catalytic oil-free compression system

Abstract

The invention provides a method for monitoring safe operation of a catalytic oil-free compression system, which comprises the following steps of: catalytically decomposing oil impurities in compressed gas by using a catalytic purifier, detecting the oil content of the compressed gas by using first oil content detection equipment before the compressed gas enters the catalytic purifier, buffering and decelerating the compressed gas by using buffering equipment, and displaying a detection result on a display screen; when the oil content of the compressed gas does not exceed the standard, the compressed gas flows into the catalytic purifier; when it is displayed that the oil content of the compressed gas exceeds the standard, gas supply to the catalytic purifier is cut off; the structure of the buffer equipment is determined according to the detection time of the first oil content detection equipment, and it is ensured that the buffer time of the compressed gas in the buffer equipment is longer than the detection time of the first oil content detection equipment. According to the method for monitoring the safe operation of the catalytic oil-free compression system, the compressed gas with the oil content exceeding the standard can be prevented from entering the catalytic purifier, the catalytic purification equipment is protected, and the safe operation of the whole machine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of compressed air purification, in particular to a method for monitoring the safe operation of a catalytic oil-free compression system. Background technique [0002] As a cheap power source, compressed air is widely used in various industries, such as equipment driving, material conveying, drying, blowing, purging, pneumatic instrument components, automatic control, etc. Compressors that prepare compressed air have high power and have high requirements for lubrication and heat dissipation during operation. Compared with oil-free compressors such as dry compressors or water-lubricated compressors, compressors that use lubricating oil can obtain better lubrication effects , higher heat dissipation efficiency and lower cost, but the compressed air produced will inevitably contain oil impurities. In special industries such as electronics, food, medicine, and textiles, since oily impurities can cause harm to pro...

Problems solved by technology

[0004] The detection rate of the oil content detection equipment in the prior art is not as fast as the flow rate of the high-pressure gas. When the oil content detection equipment detects the oil content of the compressed air at the intake end of the catalytic purification equipment, it is likely that the detection result has not yet come out, and the detected The compressed air has already entered the catalytic purification equipment, so the detection data of the oil content detection equipment has the disadvantage of lagging behind, and the oil content of the compressed air entering the catalytic purification equipment cannot be reflected in real time, let alone the compressed air entering the catalytic purification equipment. Feedback the oil content in advance

When the seal of the compressor fails and the lubricating oil leaks, the oil content detection equipment will not be able to provide early warning for the user due to this shortcoming, and cannot effectively protect the catalytic purification equipment
