The inert gas includes, but is not limited to, helium, neon, argon, or the like, the formed mixed gas is discharged into the pressurizing device 300, and the mixed gas is compressed by the pressurizing device 300, so that the pressure of the mixed gas is increased, the distance between gas molecules is reduced, and the mixed gas is easier to liquefy. Then, the mixture with the increased pressure, mainly liquid aviation kerosene, gaseous aviation kerosene, other organic waste gases, inert gases and air, is conveyed into the cooling device 400, the mixture is cooled by the cooling device 400, so that the gaseous aviation kerosene in the mixture is liquefied, and finally the liquefied liquid, mainly liquid aviation kerosene, is introduced into the recovery device 500 for recovery.

And in the gas-water mixture, only the liquefied organic waste gas is required to be recovered, therefore, the water-gas separator 520 is further arranged in the recovery tank 510, the water-gas separator 520 can separate gaseous substances from liquid substances, and then the separation of the liquefied organic waste gas from the non-liquefied inert gas and air is realized, and the separate recovery of the liquefied organic waste gas is realized.
Further, the recovery tank 510 is provided with a discharge outlet 511 for discharging liquid and an exhaust port 512 for discharging gas, and a first valve 513 and a second valve 514 are respectively communicated with the discharge outlet 511 and the exhaust port 512 in a sealing manner.
The gas-water mixture is separated by the moisture separator 520 and then periodically discharged to avoid affecting the subsequent use of the recycling device 500. Therefore, the recovery tank 510 is provided with a discharge port 511 and an air release port 512, the separated liquid can be discharged through the discharge port 511, and the separated gas can be discharged through the air release port 512. Preferably, the discharge port 511 and the air release port 512 are respectively in sealed communication with a first valve 513 and a second valve 514, the first valve 513 and the second valve 514 can respectively control the opening size of the discharge port 511 and the air release port 512, so as to respectively control the discharge speed of liquid and gas in the gas-water mixture, and when the first valve 513 and the second valve 514 are closed, the recovery tank 510 is kept sealed.
Specifically, in the radial direction of the recovery tank 510, the moisture separator 520 divides the recovery tank 510 to form a first recovery chamber 516 and a second recovery chamber 517 located outside the first recovery chamber 516, the cooling device 400 and the discharge port 511 are communicated with the second recovery chamber 517, and the gas discharge port 512 is communicated with the first recovery chamber 516.

The discharge port 511 is communicated with the second recovery cavity 517 to recover the retained liquid; the gas release port 512 is communicated with the first recycling cavity 516 to discharge the stored gas. It will be appreciated that the liquid organic waste gas has a density greater than that of the non-liquefied inert gas, air, and therefore, the discharge port 511 is provided at the bottom of the recovery tank 510 to facilitate the discharge of the liquefied organic waste gas; the vent 512 is disposed at the top of the recovery tank 510 to facilitate the discharge of non-liquefied inert gas and air.
Specifically, the cooling device 400 includes a housing 410 and a heat pipe 420 disposed in the housing 410, wherein one end of the heat pipe 420 is connected to the outlet of the pressurizing device 300 through a pipe, and the other end of the heat pipe 420 is connected to the recycling tank 510 through a pipe.

The introduction of the gas-water mixture into the recovery tank 510 and the discharge of the gas from the gas-water mixture out of the recovery tank 510 all result in a large change in the gas pressure in the recovery tank 510. The sealed containers such as the recovery tank 510 for storage all have safe air pressure values, and the air pressure in the recovery tank 510 is within the range of the safe air pressure values, so that the safe use of the recovery tank 510 can be ensured. When the gas is not discharged in time and the gas-water mixture is continuously introduced into the recovery tank 510, the gas pressure in the recovery tank 510 is continuously increased. Situations may arise where the actual pressure within the recovery tank 510 exceeds the safe pressure, creating a safety hazard. By providing the safety valve 515 capable of adjusting the air pressure in the recovery tank 510, when the air pressure in the recovery tank 510 is changed greatly or exceeds a safe air pressure value, the air pressure value in the recovery tank 510 is adjusted to be within a safe and stable range, thereby ensuring the safe use of the recovery tank 510. Meanwhile, in order to prevent the liquefied organic waste gas from flowing into the recovery tank 510 and then being restored to a gas state again due to an excessive pressure difference between the cooling device 400 and the recovery tank 510, the safety valve 515 may maintain the pressure of the liquefied organic waste gas in the recovery tank 510 within a range in which the liquefied organic waste gas is maintained in a liquid state.
In an embodiment, the cooling device 400 is communicated with the recovery tank 510 through a pipe, the pipe is provided with a barometer 600 and an electric valve 700, the barometer 600 is disposed at an upstream of the electric valve 700, the teflon tube sintering device 10 further includes a logic controller electrically connected to the electric valve 700 and the barometer 600, the logic controller is configured to increase an opening degree of the electric valve 700 when the pressure detected by the barometer 600 is higher than a set value, and decrease the opening degree of the electric valve 700 when the pressure detected by the barometer 600 is lower than the set value.
The pressurizing device 300 compresses the mixed gas, so that the pressure of the mixed gas is increased, the distance between gas molecules is reduced, and the mixed gas is easier to liquefy to form a gas-liquid mixture containing part of liquid. When the cooling device 400 cools the mixture, a set pressure exists, and the liquefaction effect of the organic waste gas is best at the set pressure. The pressure in the pipe when the liquefied organic waste gas is formed is detected by the pressure gauge 600, and compared with the set pressure value, it is determined whether the pressure of the mixture entering the cooling device 400 needs to be adjusted.
Specifically, the logic controller obtains a pressure value detected by the pressure gauge 600, compares the pressure value with a set pressure value, and when the pressure value detected by the pressure gauge 600 is greater than the set pressure value, the logic controller controls the electric valve 700 to increase the valve opening or fully open, so as to achieve an effect of reducing the pressure of the mixture entering the cooling device 400; when the pressure value detected by the pressure gauge is smaller than the set pressure, the logic controller controls the electrically operated valve 700 to reduce the valve opening or close completely, which has the effect of increasing the pressure of the mixture entering the cooling device 400.
In an embodiment, a pressure controller is disposed inside the pressurization device 300, the organic waste gas is liquefied by controlling pressure, and it is ensured that only the aviation kerosene is liquefied and the inert gas and air are not liquefied by setting a compression pressure parameter value.
