[0047] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below.

[0048] In actual application, the raw material waste liquid solvent pagoda nozzle 9 is introduced into the interior of the raw material solvent tank 2, and the nitrogen is connected by the nitrogen access hose 34. The flow of nitrogen is controlled by the nitrogen flowmeter 31 and the nitrogen pressure reducing valve 32 to enter the interior of the raw material solvent tank 2, and then the waste liquid and nitrogen are preliminarily mixed and homogenized inside the raw material solvent tank 2. During the mixing process, the pressure inside the raw material solvent tank 2 is controlled and monitored by the air compression and exhaust valve 7 and the vacuum pressure gauge 8.

[0049] The waste liquid enters the molecular sieve column 14 and the molecular sieve column 25 through the automatic control valve 19, and the molecular sieve column 14 and the molecular sieve column 25 are used to absorb the moisture in the waste liquid. At the same time, the opening and closing insulation sleeve 12 on the outside of the molecular sieve column 4 helps to maintain the working temperature of the molecular sieve column and improve the dehydration efficiency. The air pipe 13 at the top of the molecular sieve column 14 and the molecular sieve column 25 is connected to the finned heat sink 14.

[0051] Therefore, the overall dehydration process is a cyclic process.

The vent sampling port 10 allows the sampling and analysis of the solvent and the venting operation, which is convenient for monitoring the quality of the waste liquid. At the same time, it can also store qualified solvents after dehydration treatment to ensure that their purity meets the subsequent process requirements. The compressed air exhaust valve 22 and the vacuum pressure gauge 23 are used to help monitor and adjust the pressure in the tank to ensure stable storage of the solvent. The manual ball valve 26 and the automatic control valve 3 27 are set to connect the spirally wound condenser 28, which is helpful to condense and recover the steam in the solvent and improve the recovery rate of the solvent. The present invention can absorb the water content of the waste liquid and improve the purity of the waste liquid by setting the molecular sieve column 1 4 and the molecular sieve column 2 5. At the same time, the opening and closing insulation cover 12 is provided to help maintain the working temperature of the molecular sieve column 1 4 and the molecular sieve column 2 5 and improve the dehydration efficiency. The finned heat sink 14 and the control hand valve 15 can achieve the purpose of heat dissipation to prevent the molecular sieve column 1 4 and the molecular sieve column 2 5 from overheating. The present invention can form a nitrogen control system by setting a nitrogen flow meter 31 and a nitrogen access hose 34, so that the nitrogen flow entering the raw material solvent tank 2 can be accurately controlled. At the same time, the nitrogen pressure reducing valve 32 is provided to achieve the purpose of reducing the pressure of the nitrogen, ensuring that the nitrogen will not be damaged or unstable due to excessive pressure when entering the raw material solvent tank 2.
