Forced circulation evaporator

It is an evaporator that relies on external power to produce sugar rings. The forced sugar ring evaporator is more suitable for the evaporation and concentration of wastewater and waste liquids with crystallinity, scaling, high concentration, high viscosity, and insoluble solidified substances

Product Description

Structure

The system consists of various evaporators, separators, condensers, circulating pumps, inter effect pumps, vacuum and drainage systems, steam separators, operating platforms, electrical instrument control cabinets, valves, pipelines, and other systems.

working principle

① The principle of forced circulation evaporator relies on a forced circulation pump to force the solution to pass through a heating tube at a speed of 2-5m/s in one direction for evaporation, concentration or crystallization.

② The circulation of the solution in the equipment mainly relies on the forced flow generated by external power. The circulation speed in the forced circulation evaporator can reach 1.5-3.5m/s, with high heat transfer efficiency and production capacity.

③ The raw material liquid of the forced circulation pump is pumped from bottom to top by the circulation pump and flows upward along the inner tube of the heating chamber. The mixture of steam and liquid foam enters the evaporation chamber and separates. The steam is discharged from the upper part, and the fluid is blocked and falls down. It is sucked in by the circulation pump through the conical bottom and then enters the heating tube to continue the circulation.

④ During the crystallization process, the circulation flow rate can be adjusted and special separator designs can be used to adjust the crystals and crystallize them according to the required size.

characteristic

1. The high concentration ratio makes the viscous liquid easy to flow and evaporate, with short concentration time and low steam consumption.

2. The evaporation temperature is low, the heat is fully utilized, and the material liquid is heated gently, making it suitable for the concentration of thermosensitive materials.

3. The evaporator is uniformly heated inside the tube through forced circulation, with a high heat transfer coefficient, which can prevent the phenomenon of "dry wall".

4. The forced circulation evaporator has a high heat transfer coefficient, is resistant to salt precipitation and scaling, has strong adaptability, and is easy to clean.

5. The liquid enters the separator for further separation, which enhances the separation effect and gives the overall equipment greater operational flexibility.

6. Continuous feeding and discharging, the liquid level and required concentration of the material can be controlled automatically.

Scope of application

Forced circulation single effect, double effect, triple effect, and multi effect evaporators are suitable for low-temperature concentration in industries such as food, pharmaceutical, chemical, biotechnology, environmental engineering, and waste liquid recovery with high concentration, high viscosity, and insoluble solids.
