Embodiment Construction

[0053] The evaporation device of the present invention will be described with reference to the drawings.

[0054] figure 1 It is a schematic end view which shows an example of the evaporation apparatus of this invention. figure 1 The evaporation device 100 includes: a stirring tank 110 for supplying the raw material liquid; a jacket 112 for heating the inner wall 111 of the stirring tank 110; 111 of the dispersion part 120.

[0055] The stirring tank 110 is a hermetically sealed tank having a volatile component outlet 113, and is a tank that can accommodate and stir liquids such as an aqueous solution and a slurry. exist figure 1 Among them, the volatile component outlet 113 is provided above the stirring tank 110 , and the volatile component generated by the evaporation of the constituent components of the raw material liquid, which will be described later, can be discharged to the outside through the outlet 113 .

[0056] The size (capacity) of the stirring tank 110 c...

Abstract

Disclosed is an evaporator capable of more efficiently evaporating volatile components from a raw material solution and freed from troublesome maintenance and repair. The evaporating device of the present invention includes: a stirring tank, which is supplied with a raw material liquid and has a volatile component outlet; and a liquid dispensing part, which is provided in the stirring tank and allows the raw material liquid to flow down to a heat-generating part in the stirring tank. Here, the liquid distributing part has at least one channel member having an open flow path through which the raw material liquid temporarily stored in the storage part flows from the bottom to the top of the stirring tank through the liquid receiving part as the rotation shaft rotates, The open flow path is provided in the passage member between a first edge portion positioned on the side of the rotation direction of the rotation shaft and a second edge portion positioned on the opposite side of the rotation direction of the rotation shaft, and the first edge portion has a flow path along the open flow path. The axially extending raised structure of the road.

Description

technical field [0001] The present invention relates to an evaporation apparatus, and more specifically, to an evaporation apparatus capable of efficiently recovering a solvent from a liquid and efficiently concentrating the liquid. Background technique [0002] For example, in the fields of the food industry and the chemical industry, in order to recover a solvent from a liquid containing inclusions or impurities, or to concentrate the liquid containing inclusions or impurities, an evaporation device called a "falling film evaporation device" is used. [0003] Figure 7 It is a figure which shows typically the evaporation system provided with the conventional falling film evaporation apparatus. [0004] The evaporation system 900 includes: a raw material tank 910 containing a raw material liquid serving as a raw material; a falling film evaporation device 800 ; a vacuum pump 920 ; and a condenser 930 . The raw material liquid passes through the pipe 904 from the raw materi...
