MVR evaporator of skid-mounted single-screw compressor

The invention belongs to the technical field of evaporation energy saving and environmental protection facilities, and relates to an MVR evaporator of a skid-mounted single-screw compressor. The MVR evaporator comprises a frame, a preheater, a heat exchanger, a cyclone separator, the compressor, an oil pump and a condensate tank, wherein the interior of the frame is divided into a first layer anda second layer; the preheater is installed at the bottom of the first layer of the frame; the heat exchanger is vertically installed on the other side, relative to the preheater, of the first layer ofthe frame; the cyclone separator is adjacent to the heat exchanger and is installed in the frame to penetrate through the first layer and the second layer; the compressor is installed on the second layer of the frame; the oil pump is installed on the second layer of the frame and is adjacent to the compressor; the condensate tank is installed at the bottom of the first layer of the frame and is in the same line of the preheater. The MVR evaporator can increase the conversion rate of energy and lower energy consumption, is compact in structure, high in stability and capable of being suitable for different industries, and realizes automatic control over stable feeding and discharging.
