Embodiment Construction

[0041] The technical solutions of the present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0042] like figure 1 Shown is an overall schematic diagram of an implementation of the three-effect seven-stroke falling film evaporator of this embodiment.

[0043] like figure 2 Shown is a schematic diagram of the feeding chamber of the first-effect heating chamber, the feeding chamber of the first-effect heating chamber is divided into a first feeding chamber 21 of one effect and a second feeding chamber of one effect by the vertical plate 22 arranged above the material distributor 8 26. The separation method of the first-effect discharge chamber and other effect feed chambers and discharge chambers is similar to this; the various effect feed chambers mentioned in the text refer to the first-effect feed chamber, the second-effect feed chamber and the three-effect feed chamber. Material chamber....

Abstract

The invention discloses a triple effect seven-stroke falling film evaporator, wherein each feed cavity and each discharge cavity are respectively divided into a plurality of feed cavities and a plurality of discharge cavities by a riser; a previous discharge cavity of each effect is connected with a latter feed cavity of the effect. The invention improves the evaporation effect effectively by increasing the stroke, and reaches the goal of disposable material feeding and product finishing; solves the problems of seriously affecting the quality of the products, such as insufficient supply of the back stroke falling film tube feed liquid, degraded irrigation rate of periphery of the falling film tube, poor film-forming property, phenomenon of tube burning and wall drying, by the mixed design of distributor; and has the advantages of wide application range, energy-saving and environmental protection.

Description

technical field [0001] The present invention relates to a three-effect seven-stroke falling film evaporator, especially an industrial evaporator used for concentrating non-crystallized liquid materials, such as milk, fruit juice, amino acid, starch sugar, vegetable juice, etc., using multi-effect Three-effect seven-stroke falling film evaporation system with multi-stroke falling film technology. Background technique [0002] At present, falling film multi-effect evaporator has been widely used in industry. The currently used falling film multi-effect evaporator may use a falling film evaporator for each effect. The utility model patent document CN201304260Y discloses a three-effect four-stroke falling film concentration evaporator. The evaporator includes a first-effect heater, a first-effect evaporation chamber, a second-effect heater, a second-effect evaporation chamber, a three-effect heater and a third-effect evaporation chamber, a condenser, and condensed water pipes d...
