Problems solved by technology

[0004] The object of the present invention is to provide a waste liquid low-temperature evaporator based on polymer film enhanced heat exchange, to solve the problem that the existing waste liquid low-temperature evaporator proposed in the above-mentioned background technology cannot accelerate the cooling of waste water during operation, which is inconvenient The waste water is discharged quickly, and there is a certain odor during the waste water discharge process. The steam discharge for cooling will inevitably have the smell of waste water, which has a certain impact on the environment.

Abstract

The invention relates to the field of waste liquid treatment related equipment, in particular to a polymer film enhanced heat exchange-based waste liquid low-temperature evaporator. The polymer film enhanced heat exchange-based waste liquid low-temperature evaporator comprises a main body; one side of the main body is provided with a gas inlet; film pipes are arranged in the main body; a cooling mechanism wraps the film pipes; one side of the main body is provided with a water pipe; one end of the water pipe is connected with a water sump; and a partition mechanism is installed in the water sump. According to the waste liquid low-temperature evaporator, the cooling mechanism is installed at the outer side of the film pipes of waste liquid in an encircling manner; different from a traditional mode of directly discharging cold air, the cooling mechanism is that a circle of spray nozzles is installed in each of encircling water pipes of the cooling mechanism, and the spray nozzles can blow condensed gas around the film pipes, and compared with the mode that gas directly enters the gas inlet, the encircling water pipes can increase the cooled areas of the film pipes evenly, the gas issprayed stably, and the cooling speed is high.

Description

technical field [0001] The invention relates to the field of equipment related to waste liquid treatment, in particular to a waste liquid low-temperature evaporator based on polymer film enhanced heat exchange. Background technique [0002] Thin-film evaporator is a type of evaporator. It is characterized in that the material liquid flows along the heating tube wall in a film shape to conduct heat transfer and evaporation. The advantages are high heat transfer efficiency, fast evaporation speed, and short material residence time, so it is especially suitable for heat-sensitive For the evaporation of substances, the thin film evaporator has a significant effect on the cooling treatment of wastewater. It can quickly cool down the wastewater, accelerate the treatment of wastewater, and increase the amount of wastewater discharged. [0003] The existing low-temperature evaporator for waste liquid cannot accelerate the cooling of waste water during operation, which is not conveni...
