The invention discloses a vacuum pump cooling device. The vacuum pump cooling device comprises a vacuum pump, wherein the vacuum pump is connected to a water tank through a water pump; the water tank is in returning connection to the vacuum pump through a pipe to form a loop; a plurality of coiled tubes are arranged in the water tank and are connected with a cooling machine outside the water tank; and refrigerating fluid in a refrigerating machine circularly flows in the coiled tubes. Compared with the prior art, the vacuum pump cooling device has the characteristics that when the vacuum pump runs, the water pump continuously pumps cooled water in the water tank into the vacuum pump, meanwhile, the remaining water of the vacuum pump flows back to the water tank again, the water circulates continuously, the vacuum pump is cooled continuously, the water in the vacuum pump is always at low temperature, and the efficiency is guaranteed.
Description
technical field [0001] The invention belongs to the field of 2-chloroethanol production, in particular to a vacuum pump cooling device. Background technique [0002] A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate a container to obtain a vacuum. A vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space. In the process of 2-chloroethanol rectification and purification, high boiling point substances are difficult to be evaporated under normal pressure, and consume a large amount of industrial steam; the function of the vacuum pump is to pump the pressure in the material system to negative pressure State, lowering the boiling point of high boiling substances, thereby distilling them out. However, if the vacuum pump works for a long time, the water temperature in the vacuum pump is easy to rise, resulting in a decrease in the efficiency of the vacuum...
