Why does material leakage occur during the operation of the evaporator for high salt wastewater

The phenomenon of material leakage in high salt wastewater evaporators during operation may be caused by various factors. Here are some main reasons and explanations:; 1. Improper feeding control: Excessive feeding during startup: Excessive feeding at once can cause the liquid level in the separator to be too high, making compressed air operation difficult and prone to material leakage.

What are the crystallization methods of continuous crystallizer

Compared to traditional single tank intermittent crystallization, continuous crystallizer can achieve continuous crystallization production. The crystallization mode varies depending on the physical properties of different products, mainly including the following:; 1. Adiabatic vacuum crystallization After the high-temperature solution enters the insulated container, a portion of water flashes out under vacuum, thereby increasing the concentration of the solution, reducing its temperature, and creating a supersaturated state. The adiabatic vacuum crystallizer mainly adopts DTB vacuum crystallizer, OSLO vacuum crystallizer, etc.

What is the difference between falling film evaporator and rising film evaporator?

Falling film evaporator: The liquid is added from the top of the heating chamber, and under the action of gravity, it forms a film like descent along the inner wall of the tube and evaporates. The concentrated liquid enters the separator from the bottom of the heating chamber and is discharged from the bottom, while the secondary steam overflows from the top. Due to the consistency between the flow direction of the secondary steam and the flow direction of the feed liquid, it can promote the downward movement of the feed liquid and form a thin film
