Abstract

The present invention relates to a multi-effect evaporator. An efficient mechanical vapor recompression (MVR) evaporator with a resource recycling function comprises at least two evaporator effect bodies. Each evaporator effect body comprises an evaporator body; the evaporator body comprises a heater and a separation chamber connected to the heater; the evaporator bodies are connected sequentially; an outlet of the separation chamber of one evaporator body is connected to a heated steam inlet of a next adjacent evaporator body; the outlet of the separation chamber of the evaporator body in the rear is connected to an air inlet of a compressor; and an air outlet of the compressor is connected to the heated steam inlet of the evaporator body in the forefront by a steam pipe. The heater is a vertical falling film tubular heater. The heater comprises vertical falling film heating tubes, and a coating film distributor is arranged on the top of the vertical falling film heating tubes. According to the efficient MVR evaporator provided by the present invention, secondary use of steam is realized by using the compressor and the thermal energy recovery rate is close to 100%.

Description

technical field [0001] The invention relates to the technical field of evaporation and concentration, in particular to a multi-effect evaporator. Background technique [0002] With the rapid development of fermentation industry, pharmaceutical industry, chemical and smelting industry, and paper industry at home and abroad, more and more industrial sewage and wastewater are produced, and the pressure on environmental governance of production enterprises is also gradually increasing. Sewage and wastewater treatment and sewage and wastewater treatment processes The development and utilization of the recovery device for the waste gas produced is becoming more and more important. Evaporation, concentration, crystallization, separation and drying of industrial waste water is one of the most economical and scientific waste water treatment methods. During the evaporation process, recyclable resources (such as alcohol and other light components) can be separated and condensed. The co...
