9. The purification method based on the purification apparatus for high-quality methyl chloroformate according to any one of claims 1 to 8, characterized by comprising the steps of:
step 1: adding water into the reaction kettle (1) by turning on a delivery pump (13), then adding the prepared methyl chloroformate solution into the reaction kettle (1) from a feeding seat (202), and then heating the reaction kettle (1) by controlling a heating coil (5) through a heating device box (7) to heat the mixed solution to 75 degrees;
step 2: the motor (8) is turned on to enable the rotating shaft (15) to drive the stirring blade (17) to rotate, the mixed solution can be stirred through the rotation of the stirring blade (17), so that the mixed solution can be uniformly heated, the prepared methyl chloroformate solution is heated to 75 ℃ to reach a boiling point, and the methyl chloroformate solution is gasified;
and step 3: then, the gasified methyl chloroformate steam is discharged through an exhaust seat (203) by opening a first electromagnetic valve (9), then enters a cooling pipe (21) arranged in a cooling device box (11) through a first connecting pipe (10), and then is sprayed out through a spray head (22) by opening a liquid pump (24), so that the liquid pump (24) pumps the cooling liquid in the cooling device box (11), the cooling liquid enters the cooling pipe (21) through a return pipe (23), and the cooling liquid can be effectively cooled down through a spiral cooling pipe (19), the sprayed cooling water is stored in the cooling device box (11), and the cooling water can be recycled;
and 4, step 4: the cooled methyl chloroformate is liquefied into a methyl chloroformate solution, the methyl chloroformate solution flows in the spiral cooling pipe (19), then enters the storage box (27) through the connecting pipe II (26) through the conveying pipe (20) to be stored, and the refined methyl chloroformate solution can be conveniently taken and used through the arranged discharging seat (28);
and 5: the unliquefied gas continues to enter the purifying device box (30) through the connecting pipe III (29), the gas can be well filtered and purified through the two installed filtering devices (33), and when the gas monitoring device (31) detects that the gas reaches the discharge standard, the gas is opened through the control electromagnetic valve II (32), so that the gas is discharged.
