Energy-saving and environmental-friendly waste water treatment system reliable in adjustment, through low-temperature evaporation

Abstract

The invention provides an energy-saving and environmental-friendly waste water treatment system reliable in adjustment, through low-temperature evaporation, particularly relates to the technical fieldof waste water treatment. The energy-saving and environmental-friendly waste water treatment system comprises a treating chamber, wherein the treating chamber sequentially comprises a waste water steam evaporating chamber and a waste water steam condensing chamber from bottom to top; a condenser is arranged at the bottom in the waste water steam evaporating chamber; the bottom of the waste watersteam evaporating chamber is communicated with a feeding pond and a concentrated solution collecting tank cooling and crystallizing chamber through pipelines; an evaporator and a steam condensing water tray are sequentially arranged in the waste water steam condensing chamber from top to bottom; the lower end of the waste water steam condensing chamber is connected with a condensation water collector through a pipeline; the condensation water collector is connected with a condensation water pump and a vacuum pump through pipelines; a liquid outlet pipe is connected to the liquid outlet end ofthe condenser, and an air inlet pipe is connected to the air inlet end of the condenser; a first flow controller is arranged on the liquid outlet pipe, and a first compressor is arranged on the air inlet pipe; and the other end of the liquid outlet pipe is connected with a liquid inlet end of the evaporator, and the other end of the air inlet pipe is connected with an air outlet end of the evaporator. The energy-saving and environmental-friendly waste water treatment system disclosed by the invention is notable in energy-saving effects; heating equipment is combined with condensing equipment;the floor space is small; and space is saved.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an energy-saving, environment-friendly, reliable and adjustable low-temperature evaporation wastewater treatment system. Background technique [0002] Traditional domestic wastewater treatment conventional evaporators generally adopt high-temperature steam distillation. At the same time, different cold and heat sources are used for heating and condensation to perform high-temperature evaporation and low-temperature condensation respectively. The equipment is separated, which occupies a large area and wastes energy and space. [0003] Therefore, there is an urgent need for an energy-saving, environmentally friendly, reliable and adjustable low-temperature evaporation wastewater treatment system that can solve the existing problems. Contents of the invention [0004] The purpose of the present invention is to provide an energy-saving, environmentally frie...
