Embodiment 1

[0029] like figure 1 As shown in , the catalytic oil-free air supply device of the present invention includes a catalytic purifier 6 , an oil content detection device 11 and a heat exchanger 4 . The catalytic purifier 6 includes a heating chamber 6-1, a catalytic purification chamber, a catalytic intake pipe 5 and a catalytic exhaust pipe 7. The catalytic intake pipe 5 introduces compressed gas into the heating chamber 6-1, and the heating chamber 6-1 heats the compressed gas When the temperature reaches 180-200°C, a catalyst is installed in the catalytic purification chamber, and the catalytic purification chamber is wrapped with thermal insulation cotton. The compressed gas enters the catalytic purification chamber after being heated, and undergoes a complex catalytic oxidation reaction under the action of the catalyst to remove oil impurities. That is, the C6+ carbon-containing compounds are decomposed into carbon dioxide and water, and the purified compressed gas is led ou...

Embodiment 2

[0035] The difference between the catalytic oil-free air supply device in the present embodiment and the embodiment 1 is that the second exhaust port 4-4 is provided with an external air supply pipe 8, and the external air supply pipe 8 is connected to the gas-using equipment to the outside. After the compressed gas discharged from the heat exchanger 6 is buffered by a U-shaped heat exchange pipe of the heat exchanger 4, it is led out to the gas-consuming equipment by the external gas supply pipe 8. The external gas supply pipe 8 is also provided with an air-to-air exhaust pipe. The exhaust pipe is used to discharge compressed gas to the air, and the external gas supply pipe 8 is provided with an air supply valve and an exhaust valve. When the detection result of the oil content of the compressed gas reaches the standard, the gas supply valve is opened and the exhaust valve is closed, and the compressed gas flows into the gas equipment through the external gas supply pipe 8; wh...

Embodiment 3

[0037] like Figure 4 As shown in, the catalytic oil-free compression system of the present invention includes a compressor 1, an oil-gas separator 14, a gas-liquid separator 2, and the catalytic oil-free air supply device as described in Embodiment 1 or Embodiment 2, the compressor The air inlet of 1 is provided with an air filter assembly 15 for filtering gas, the exhaust port of the compressor 1 is communicated with the air inlet of the oil-gas separator 14, and the exhaust port of the oil-gas separator 14 is connected with the air-liquid separator 2. The air inlet is connected, the air outlet of the gas-liquid separator 2 is provided with a gas-liquid separation exhaust pipe 3, and the gas-liquid separation exhaust pipe 3 is connected to the first air inlet 4-1 of the heat exchanger 4, that is, through the heat A U-shaped heat exchange pipe in the exchanger 4 communicates with the catalytic intake pipe 5 . The compressor 1 may be a screw type oil-lubricated compressor, an...

Abstract

The invention provides a catalytic oil-free gas supply device and a catalytic oil-free compression system.The catalytic oil-free gas supply device comprises a catalytic purifier, a catalytic gas inlet pipe and a catalytic exhaust pipe are arranged on the catalytic purifier, and an oil content detection device and a buffer device are arranged on the catalytic exhaust pipe; the catalytic gas inlet pipe is used for guiding compressed gas into the catalytic purifier, the catalytic purifier is used for catalytically decomposing oil impurities in the compressed gas, and the catalytic gas exhaust pipe is used for guiding the compressed gas in the catalytic purifier into the buffer equipment; the oil content detection equipment is used for detecting the oil content of the compressed gas before the compressed gas enters the buffer equipment, the buffer equipment is used for buffering the compressed gas and discharging the compressed gas, and the detection rate of the oil content detection equipment is not greater than the rate of the compressed gas passing through the buffer equipment. When the catalytic oil-free gas supply device is used for supplying gas, the oil content of the compressed gas to be input into the gas consumption equipment of a user can be detected in real time or in advance, and the gas consumption quality of the user is guaranteed.

Description

technical field [0001] The invention relates to the technical field of degreasing and purification of compressed gas, more specifically to a catalytic oil-free gas supply device and a catalytic oil-free compression system. Background technique [0002] As a cheap power source, compressed gas is widely used in all walks of life, such as equipment drive, material conveying, drying, blowing, purging, pneumatic instrument components, automatic control, etc. The quality requirements are high, and some clearly require the use of oil-free compressed gas. However, the compressed gas produced by the compressors that are being widely used will inevitably contain oil impurities. In the prior art, a catalytic purifier is usually arranged at the exhaust end of the compressor to construct an oil-free compression system. After the compressed gas is introduced into the catalytic purifier, the oil impurities in it will be catalytically decomposed into carbon dioxide and water, so as to remov...
