The preheater 2 is mainly used for heating the mixed gas at the outlet of the liquid separating tank 1, and can automatically set the heating temperature to dry the mixed gas after liquid separation, so that the mixed gas is prevented from carrying liquid into a subsequent system.
The thermometer 3 detects the temperature of the mixed gas in real time.
The primary fiber separator 4 mainly performs separation and purification of the mixed gas.
The secondary fiber membrane separator 5 is mainly characterized in that the primary fiber separator 4 is in a standby state when in work, or the separation and purification precision of the primary fiber separator 4 cannot meet the requirements of users, 4 and 5 can be connected in series to carry out secondary separation and purification, and the separation and purification precision is further improved.

The gas purifier 9 purifies the discharged air to reach the emission standard, and prevents the air from being polluted.
The working principle of the utility model is as follows:
the gas-liquid separation tank 1 separates the mixed gas entering the device, when the mixed gas enters the gas-liquid separation tank 1, the liquid carried in the mixed gas is absorbed and intercepted by the absorption net in the gas-liquid separation tank 1 and collected in the tank, and when the liquid level of the liquid collected in the tank reaches a high report value, the valve under the gas-liquid separation tank 1 is triggered to automatically discharge the liquid, thereby achieving the purpose of continuous work. The mixed gas after liquid separation enters a preheater 2, the mixed gas is heated to further dry the mixed gas, a thermometer 3 is arranged behind the dried mixed gas to measure the temperature, and the preheater 2 can automatically heat according to the temperature change, so that the mixed gas always reaches a dry and liquid-free state. If the temperature of the mixed gas measured by the thermometer 3 is too low to be satisfactory to enter the next step due to the failure of the work of the gas-liquid separation tank 1 or the preheater 2, the system automatically opens the emptying to empty the mixed gas discharged from the thermometer 3.
The mixed gas from the thermometer 3 enters a first-stage fiber separator 4, a bundle-shaped fiber membrane is arranged inside the first-stage fiber separator 4, the mixed gas enters the first-stage fiber separator 4 through self power, the speed of the gas with different components in the mixed gas passing through the fiber membrane is different, the passing time is different, the gas with different components can be separated through the time difference between the front and the back, then the separated gas moves to different directions through special components inside the fiber separator, useful product gas comes out from the bottom of the fiber separator 4, and useless gas comes out from the top. The structure and the working principle of the secondary fiber membrane separator 5 and the primary fiber membrane separator 4 are completely the same, under general conditions, the primary fiber separator 4 completely meets the requirements of users, the secondary fiber membrane separator 5 is in a standby state, if the precision required by the users is high, the primary fiber membrane separator 4 and the secondary fiber membrane separator 5 can be connected in series to be separated and purified again, and the high separation and purification precision is achieved.
The finished gas from the bottom of the fiber separator enters a thermometer 7 and a gas online analysis device 8, so that the temperature of the gas can be accurately detected online in real time, the gas content of the main components can be analyzed, and the requirements of users can be met more accurately. The useless gas from the top of the fiber separator passes through the exhaust gas on-line monitoring device 6, the amount of harmful gas in the exhaust gas is accurately detected, and the harmful gas content reaches the standard and is automatically discharged. If the amount of harmful gas exceeds the standard, an alarm is given, and meanwhile, the gas purifier 9 is automatically started to purify the exhausted gas until the emission standard is met.
The on-line separation and purification of the mixed gas of a plurality of components are carried out by the selective passing of the fiber membranes in the fiber membrane separation and the difference of the passing rate and the time of the gas of different components.
