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, and respectively arranging first oil content detection equipment and second oil content detection equipment at the gas inlet end and the gas outlet end of the catalytic purifier to detect the oil content of the compressed gas, the oil content of the compressed gas purified by the catalytic purifier is firstly detected by the second oil content detection equipment, then the compressed gas is buffered and decelerated by the buffer equipment, and the buffer time of the compressed gas in the buffer equipment is longer than the detection time of the second oil content detection equipment; detection results of the first oil content detection equipment and the second oil content detection equipment and a difference value between the detection results are displayed on the display screen. According to the method, a user can master the working states of the compressor and the catalytic purifier in real time, whether the compressor leaks oil or not and whether a catalyst in the catalytic purifier faces the overload risk or not are judged, the gas quality of the user is guaranteed, and the safety of the whole machine is protected.

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] Although, installing oil content detection equipment at the exhaust end of the compressor can confirm whether the compressor is running out of oil, and installing oil content detection equipment at the exhaust end of the catalytic purification equipment can confirm whether the oil removal efficiency of the catalytic purification equipment is normal, However, the detection rate of the oil content detection equipment in the prior art is not as fast as the flow rate of high-pressure gas. Often, the detected compressed air has already entered the user's gas equipment before the detection results come out, so that the oil content detection equipment will The detection data lags behind, and the oil content cannot be fed back before the compressed air enters the user's gas equipment, and the quality of the gas used by the user cannot be effectively guaranteed.
