Low-temperature dehumidifying evaporator

Abstract

The invention discloses a low-temperature dehumidifying evaporator. The low-temperature dehumidifying evaporator comprises a dehumidifying condenser, a liquid outlet pipe is communicated with the topof the dehumidifying condenser, a compressor is fixedly connected with the end, away from the dehumidifying condenser, of the liquid outlet pipe, a heat dissipater is fixedly connected with the left side of the compressor through the liquid outlet pipe, a backflow pipe is communicated with the right side of the top of the heat dissipater, and a cyclic draught fan is fixedly connected with the right side of the backflow pipe; and a gas-liquid separator is fixedly connected with the right side of the cyclic draught fan through the backflow pipe. The evaporating temperature of the low-temperaturedehumidifying evaporator is low, the temperature is 50-55 DEG C under a normal operation state, the safety of the equipment is greatly improved, and meanwhile, the concentration cost is lowered; andunder the situation that the sunlight is sufficient, the purpose of energy conservation is achieved by converting the solar energy to be electricity energy, the concentration cost is lowered, and theproblems that part of existing evaporators realize the purpose of evaporating at a lower temperature and saving energy consumption by reducing the evaporating temperature, however a large amount of electricity energy still needs to be consumed, and thus the concentration cost cannot be effectively reduced are solved.

Description

technical field [0001] The invention relates to the technical field of evaporation and concentration, in particular to a low-temperature dehumidification evaporator. Background technique [0002] Evaporation and concentration process is widely used in chemical, pharmaceutical, wastewater treatment and other industries, the purpose is to remove the moisture in the material, to achieve the purpose of extracting solid products in the material or reducing the amount of the material. Most of the current methods are multi-effect evaporation and mechanical vapor recompression. The obvious disadvantages of the former are large steam consumption and low energy utilization rate. The latter recovers the secondary steam through the steam compressor, which greatly improves the energy utilization rate. , and is currently the most energy-saving and environmentally friendly evaporation method. But when the evaporating temperature is low, the efficiency of the compressor will drop significa...
