Abstract

The invention relates to low-temperature stirring evaporation equipment which comprises an evaporator, a steam input pipe, a steam output pipe, a pressure reducing device, a stirring device and a heat pump system; the evaporator is used for evaporating waste liquid and comprises an outer wall and a heat insulation plate arranged on at least part of the outer wall, and a steam gap is formed between the heat insulation plate and the outer wall; the steam input pipe and the steam output pipe are connected with the steam gap so as to input and output steam into and out of the steam gap; the pressure reducing device is connected with the evaporator so as to vacuumize the interior of the evaporator; the stirring device comprises a stirring shaft at least partially arranged in the evaporator and a spiral blade arranged on the stirring shaft; the stirring shaft and the spiral blade are internally provided with communicated hollow structures, and a heat exchange medium enters from one end of the stirring shaft, passes through the spiral blade and flows out from the other end of the stirring shaft; and the heat pump system is connected with the steam input pipe and the steam output pipe. The low-temperature stirring evaporation equipment is low in energy consumption and large in heating area, and waste liquid in the evaporator can be uniformly heated, so that the heating efficiency of equipment is improved.

Description

technical field [0001] The invention relates to low-temperature stirring evaporation equipment, which belongs 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 industrial wastewater has caused serious environmental pollution. In order to protect the environment, it is necessary to strictly control the discharge of sewage. Every enterprise that produces industrial wastewater has discharge indicators. The concentrate or crystalline salt is outsourced to the hazardous waste treatment center; there is no discharge target, the effluent can only be reused, and the remaining concentrate or crystalline salt is outsourced to the hazardous waste treatment center, and those without treatment equipment can only be used The outsourcing price of wastewater treatment varie...
