Problems solved by technology

However, when the ambient temperature is low, for example, in winter in northern cities, the ambient temperature is below zero, and it takes a long time and energy to heat the waste liquid to 30-40°C
Moreover, since there is no steam generated in the evaporation tank at this time, the compressor in the heat pump system cannot be supplemented by the heat exchange medium, and will be in a low-load operation state, and thus cannot provide heat exchange medium for heating the waste liquid
Therefore, the equipment is often unable to start, and the compressor is easily damaged

Abstract

The invention relates to a low-temperature vacuum evaporator used at a low ambient temperature, comprising: an evaporation tank used for evaporating a waste liquid and provided with a first steam outlet, a concentrated liquid outlet and a waste liquid inlet; a first heat exchanger which is arranged inside or outside the evaporation tank; a condensation tank which is connected with the first steamoutlet through a steam pipeline, wherein a second heat exchanger is arranged in the condensation tank and used for cooling the generated steam; a heat pump system which comprises a compressor and a throttling device which are connected with the first heat exchanger and the second heat exchanger respectively and provides heat exchange media for the first heat exchanger and the second heat exchanger; a pressure reducing device which is used for vacuumizing the evaporation tank and the condensation tank; and a preheating assembly which is used for heating the waste liquid and/or heating the heatexchange medium. The low-temperature vacuum evaporator directly acts on waste liquid and/or a heat exchange medium, the waste liquid can be rapidly heated in the evaporation tank to form steam, heat exchange is conducted between the steam and the heat exchange medium in the condensation tank, and then the heat exchange medium is supplemented for the compressor.

Description

technical field [0001] The invention relates to a low-temperature vacuum evaporator used under low ambient temperature, belonging to the field of environmental protection equipment. Background technique [0002] 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 The factory generally charges according to the treatment volume, such as several thousand yuan per ton. Therefore, the cost of sewage treatment for enterprises has also increased significantly. [0003] Heat pump technology is an efficient, envir...
