Abstract

The invention relates to an evaporator, a cold and heat combined supply system of the evaporator and a vacuum generator. The evaporator comprises a waste liquid barrel, the cold and heat combined supply system and the vacuum generator, wherein waste liquid in the waste liquid barrel enters the cold and heat combined supply system through a liquid inlet valve arranged in a pipeline; the waste liquid is evaporated and concentrated, concentrated liquid is discharged; and steam is condensed into water and pumped into the vacuum generator to be discharged; and a refrigerant is subjected to closed-loop circulation in the cold and heat combined supply system, subjected to compression temperature rise and subjected to heat exchange with the waste liquid, then subjected to discharging and expansiontemperature reduction, sequentially cools the steam and water in a circulation water tank and then is subjected to compression recirculation.

Description

technical field [0001] The invention relates to the technical field of waste liquid treatment, in particular to an evaporator, a combined cooling and heating system, and a vacuum generator. Background technique [0002] PCB, electroplating and other industries will produce waste liquid in the production process. The main pollutants are COD, nitrogen, phosphorus and heavy metals. If discharged without treatment, it will seriously pollute the environment and endanger human health. Waste liquid has the characteristics of many types of pollutants, high concentration, small amount and dispersed distribution. Common treatment methods include chemical method, membrane separation method and evaporation method. At present, most enterprises outsource the disposal of waste liquid, and there are problems such as high disposal costs, untimely transshipment, and backlog storage that affect the normal production of enterprises. [0003] In the prior art, evaporation technology is used to...
