Abstract

The invention discloses a water circulation device of a vacuum pump. The water circulation device comprises an extruder, wherein the extruder is connected with a gas washing tank through a vacuum gas sucking pipe; the gas washing tank is connected with one end of a water circulation vacuum pump through the vacuum gas sucking pipe; the other end of the water circulation vacuum pump is connected with a water gas separator through a pipeline; the water gas separator is connected with a water return tank through a water pipe and a gas water pipe; and the bottom of the water return tank is connected with the water circulation pump through the water pipe. Compared with the traditional device, the water circulation device is simple in structure and scientific in design; the purposes that waste gas are not discharged outside and wastewater are recycled in the waste gas treating process are achieved; the water circulation device does not pollute the surrounding environment; and meanwhile water can be remarkably saved.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a vacuum pump water circulation device. Background technique [0002] The water circulation vacuum pump is an essential equipment for the manufacture of engineering plastics. The low-molecular volatiles pumped out by the vacuum pump during the extrusion process are generally discharged directly with the exhaust port. Since the water circulation pump uses water as the sealing medium, the water is also discharged directly with the air, resulting in an increase in the discharge of waste water and waste gas, which directly affects environmental pollution. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to address the deficiencies of the prior art and provide a vacuum pump water circulation device that effectively protects the environment without external discharge of waste water and waste gas. [0004] Technical s...
