Three-effect evaporator features and advantages

Three-effect evaporator features

1. Features of the device: energy saving

The evaporated secondary steam acts as a heat source for the preheater, which not only heats the raw material but also cools the secondary steam, reduces steam consumption, and reduces the amount of cooling water. The use of two-effect evaporation can greatly reduce energy consumption by 40%.

2, Anti-blocking design

Mainly from the following aspects to avoid congestion:

(1) Set the sprinkler to clean the defoamer.

(2) The discharge pump impeller adopts an open impeller, which is not easy to block.

(3) The circulation rate of the liquid in the tube is fast, reaching 1 m/s, so the tube is not easy to scale.

3, Fast, good discharge

The external heating method and the negative pressure evaporation method have the advantages of large evaporation capacity, high speed, and can meet the concentration of heat sensitive materials, no running materials and adhesive materials, and the products are discharged well.

4, Reduce the occurrence of blockage and scaling

A swirl plate is arranged in the evaporator, and the liquid of the heater enters the evaporator from the lower to upper part of the circulation pipe during the evaporation process. The device has installed the tangential feed pipe to be mentioned below. In order to speed up the circulation of the liquid through the whole system, after the tangential flow of the liquid enters, a plurality of swirling plates with a rotation angle are arranged on the inner wall of the hair. The purpose is to make the rotation of the liquid, generate the whirlwind driving force, accelerate the speed of the system liquid, and increase the heat transfer coefficient of the system and increase the flushing opportunity after the system liquid rises, reducing the occurrence of blockage and scaling.

5, Improve the rotation efficiency

The evaporation chamber is fed in a tangential direction and is angled 45° above the feed tube to cover the plate. After the liquid enters the evaporation chamber from the top of the heating chamber, the water will form a flash due to the strong vacuum and the temperature of the liquid close to the evaporation temperature. The upper baffle can reduce the chance of the material being vacuumed away. In general evaporators, materials may be carried away or fouled in the upper part, which seriously affects the normal operation of the system. At the same time, the baffle plate conducts the flow of the liquid and the steam to improve the rotation effect.

What are the advantages of the three-effect evaporator?

1. The three-effect evaporator adopts falling film vacuum operation, the material has short heating time and low evaporation temperature, which can reduce equipment corrosion.

2. The three-effect evaporator uses multi-effect evaporation to utilize the latent heat of steam to minimize heat emissions and reduce raw steam consumption.

3, The use of three-effect evaporator heat exchange tube is not easy to scale, high heat transfer efficiency, large operational flexibility, long operating cycle.https://www.heczb.com/
