Embodiment Construction

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

[0042] Such as figure 1 As shown, the overall schematic diagram of an embodiment of the three-effect seven-stroke falling film evaporator of this embodiment.

[0043] Such as 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 and a second feeding chamber by a vertical plate 22 arranged above the material distributor 8 26. The separation method of the one-effect discharge chamber and other feed-in chambers and discharge chambers is similar; the various-effect feed cavities mentioned in the text refer to the one-effect feed cavity, the two-effect feed cavity and the three-effect feed cavity. Material cavity.

[0044] When the material is evaporated, the thin material ...

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 invention relates to a three-effect seven-stroke falling film evaporator, in particular to a kind of industrially used to concentrate non-crystallized liquid materials, such as milk, fruit juice, amino acids, starch sugar, vegetable juice, etc. 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 adopt 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 one-effect heater, one-effect evaporation chamber, two-effect heater, two-effect evaporation chamber, three-effect heater and three-effect evaporation chamber, condenser and condensate pipes leading from each heater, each heater A plurality of vertic...
