Description

Technical Field

[0001] The utility model belongs to the technical field of waste liquid treatment, and specifically relates to a waste liquid concentration and rectification tower. Background Art

[0002] In the waste liquid reduction and even zero emission technology, evaporation concentration equipment and processes are increasingly respected. For example, MVR, multi-effect evaporator, membrane evaporation, etc., all use thermal evaporation technology to achieve wastewater reduction.

[0003] Patent application number: 202222770697.3 discloses a waste liquid concentration distillation tower. By setting a heat utilization component, when hot steam is generated for waste liquid treatment, the air pump generates suction, and the suction is transmitted to the inner cavity of the copper heat pipe through the vertical pipe, generating negative pressure in the inner cavity of the copper heat pipe, and then the suction is transmitted to the inner cavity of the distillation tower body through the connection between the copper heat pipe and the suction pipe, and the hot steam in the inner cavity of the distillation tower body is absorbed. When the hot steam enters the interior of the copper heat pipe, the thermal conductivity of the copper heat pipe is used to heat the water inside the water tank, and the hot steam will retain some heat after heating the water, and then the heat is re-injected into the interior of the distillation tower body through the connecting pipe to heat the waste liquid, thereby utilizing the heat inside the hot steam. The hot steam is mostly directly condensed and discharged to the external waste gas treatment equipment, which causes a waste of heat inside the hot steam. By setting, when the waste liquid is treated During the concentration process, the water pump draws waste liquid from the inner cavity of the waste liquid tank through the sewage inlet pipe, injects the waste liquid into the inner cavity of the distillation tower body through the sewage discharge pipe connected to the distillation tower body, and then heats the waste liquid through the operation of the electric heater to evaporate and concentrate the waste liquid. The steam generated during evaporation rises upward, and the impurities floating in the steam are filtered through the ultrafiltration membrane, the water-proof membrane and the microporous filter membrane to prevent the impurities from entering the interior of the heat utilization component and causing blockage of the pipes inside the heat utilization component. By setting up a gas dryer, when the hot steam enters the interior of the gas dryer through the intake pipe, the water inside the steam is dried by the gas dryer, which can not only prevent the water from re-entering the inner cavity of the distillation tower body and causing an increase in the evaporation time, but also can reheat the hot steam through the heating performance of the gas dryer to fully heat the water and assist in increasing the evaporation efficiency of the waste liquid.

[0004] However, when the waste liquid is concentrated and distilled, some impurities will adhere to the outer wall of the heating device. If used for a long time, the heating device will be unable to heat the waste liquid to the distillation temperature. Utility Model Content
