Evaporation, concentration, separation and recovery equipment

Abstract

The invention discloses evaporation, concentration, separation and recovery equipment. The equipment comprises recovery equipment; the recovery equipment is composed of a preheater, a climbing film evaporator, a reaction kettle, a separation tank, a first collection tank, a second collection tank, a first heat exchanger, a second heat exchanger and a vacuum pump. A concentrated solution separatedby the equipment is deposited at the bottom of the separation tank, a second valve is opened, the concentrated solution flows into the reaction kettle from a joint E under the action of gravity; the interlayer of the reaction kettle is externally heated, a stirrer performs stirring, generated steam enters the heat exchanger to be condensed; and condensate flows into the first collection tank froma joint F under the action of gravity; the separated high-purity concentrated solution flows into the the second collection tank through a G joint under the action of gravity. The equipment has the advantages of high integration degree, capability of saving equipment and space, good economical efficiency, high operability, high flexibility, safety and controllability; the vacuum pump can be closedafter the system operates stably. And the steam recovery rate can be increased, energy is effectively utilized, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of concentration, separation and recovery, and more specifically relates to a device for evaporation, concentration, separation and recovery. Background technique [0002] The publication number is: CN106634037B A kind of capsicum red solvent extraction liquid evaporation method and evaporation equipment [0003] The invention provides a method for evaporating capsanthin solvent extract, comprising the following steps: 1) capsanthin solvent extract first enters a rising film evaporator for vacuum evaporation, 2) step 1) the liquid phase after flash evaporation enters falling film evaporation In the tube side of the falling film evaporator, it flows from top to bottom and exchanges heat with the hot water at 70-80°C in the shell side of the falling film evaporator; 3) The liquid phase discharged from the falling film evaporator enters the rotary thin film evaporation 4) the liquid phase at the bottom of the ...

AI Technical Summary

Problems solved by technology

[0012] The object of the present invention is to provide a kind of evaporative concentration separation and recovery equipment, which solves the problem of not fully combining the prior art integration equipment in the prior art: integrating several evaporators with different conditions such as vacuum degree and temperature, without Fully consider the common points of each evaporator, and there is no reasonable explanation on how to achieve various vacuum degrees and temperatures in one system. Using steam heating requires heating water to the boiling point, which requires high energy consumption. Steam is 100°C at normal temperature and pressure. Above, there is a requirement for the boiling point of the raw material
