Device for treating production line wastewater through combination of heat pump concentration device and drying device

Abstract

The invention discloses a device for treating production line wastewater through combination of a heat pump concentration device and a drying device, and relates to the technical field of environmental protection equipment, in particular to a first distillation still and a second distillation still, the outer side of the first distillation still is connected with a stock solution inlet pipe, and a pneumatic diaphragm pump is installed at the end of a concentrated solution outlet pipe; and the top of the first distillation kettle is connected with a steam outlet pipe, the second distillation kettle is communicated with the first distillation kettle through a concentrated solution transmission pipe, the other side of the second distillation kettle is provided with a filter box, and the tail end of the steam transmission pipe is connected with a first condensation pipe. According to the device for treating the production line wastewater through the combination of the heat pump concentration device and the drying device, the purposes of energy conservation, treatment and recovery of cleaning water are achieved by effectively utilizing cold and heat exchange in a negative pressure state through a heat pump technology, concentrated liquid is reduced and dried through negative pressure drying equipment, the maximum economic benefit is achieved, the daily operation cost of an enterprise is reduced, and daily operation and maintenance personnel and cost are reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a device for treating production line wastewater by combining a heat pump concentration and drying device. Background technique [0002] The treatment of industrial wastewater has always been an important issue in industrial environmental protection. The previous treatment method was to add chemicals to the wastewater, through a large number of procedures, supplemented by a large number of treatment equipment, to clean up the impurities in the wastewater. With the modern scientific With the development of technology, and the use of chemicals to treat wastewater can not meet the environmental protection standards in many cases, so now it is possible to directly solve the problem of wastewater treatment through the combination of several environmental protection equipment, and directly reuse the treated water. [0003] The existing related equipment for w...
