High-treatment-capacity low-temperature vacuum evaporator

Abstract

The invention relates to a high-treatment-capacity low-temperature vacuum evaporator which comprises an evaporation tank which is provided with a steam outlet and a concentrated solution outlet; a condensation tank which is connected with the steam outlet; heat exchangers which are respectively arranged in the evaporation tank and the condensation tank; a heat source device which comprises a compressor unit and an air inlet port, wherein the compressor unit comprises a plurality of compressors which are arranged in parallel, each compressor is connected with the air inlet port and the heat exchanger, the air inlet port is used for distributing gaseous refrigerants into each compressor, and forming a heat exchange medium provided for the heat exchanger so as to heat the waste liquid in the evaporation tank, and evaporating the waste liquid to form water vapor; a refrigerating device which is connected with the heat source device and the heat exchanger; and a pressure reducing device which is used for vacuumizing the evaporation tank. The high-treatment-capacity low-temperature vacuum evaporator has the advantages that the treatment capacity can be greatly increased, and the high heat exchange efficiency and the high effluent quality can be realized at lower cost.

Description

[0001] This application is a divisional application. The application number of the parent case of the divisional application is 202010742419.X, the application date is July 29, 2020, and the invention name is "large-capacity low-temperature vacuum evaporator". technical field [0002] The invention relates to a large-capacity low-temperature vacuum evaporator, which belongs to the field of environmental protection equipment. Background technique [0003] Energy issues and environmental issues have become increasingly prominent in industrial production, which puts forward higher requirements for energy-saving technologies. The discharge of hazardous waste liquids such as industrial wastewater has caused serious environmental pollution. In order to protect the environment, it is necessary to strictly control the discharge of sewage. All large-scale landfill enterprises need to discharge sewage to special sewage treatment plants for treatment before discharge. Sewage treatment ...
