Double Effect Forced Circulation Evaporator

The forced circulation evaporator consists of two major parts: a heat exchange chamber and a crystallization evaporator. Through a circulation pump, the liquid circulates in the tubes and is heated to superheat at a pressure higher than the normal boiling point of the liquid. After entering the separator, the pressure of the liquid drops rapidly, causing part of the liquid to flash or boil rapidly. The secondary steam generated by evaporation enters the next-effect evaporator for heating or enters the condenser for condensation. The concentrated liquid is pumped to the salt separator by a circulation pump, and the real brine is effectively separated in the salt separator.

The forced circulation evaporator is a low-consumption and energy-saving concentration and crystallization equipment developed by our company, with the characteristics of fast liquid flow rate, fast evaporation, and not easy to scale.

The double-effect forced circulation evaporator consists of two heating chambers.

The forced circulation evaporator consists of each effect heating chamber, evaporation crystallization chamber, condenser, circulation pump, vacuum and drainage system, gas-liquid separation chamber, secondary steam flash tank, salt separator, operating platform, detection instrument and electrical instrument control cabinet and valve and pipeline system.

1. The whole system is reasonably designed, beautiful, stable in operation, low in energy consumption, and low in steam consumption; the concentration ratio is large, and the forced circulation type makes the viscous liquid easy to flow and evaporate, and the concentration time is short;

2. The special design can achieve switching and efficiency change through simple operation to adapt to the production of different products;

3. The evaporation temperature is low, the heat is fully utilized, and the liquid is heated gently, which is suitable for the concentration of heat-sensitive materials;

4. The evaporator is heated evenly in the tube through forced circulation, and the heat transfer coefficient is high, which can prevent dry wall phenomenon;

5. The liquid enters the separator and is separated again, which strengthens the separation effect and makes the overall equipment have greater operational flexibility;

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

7. The whole set of equipment has a compact structure, small footprint, simple and smooth layout, and represents the development direction of large-scale complete evaporation equipment.

It is suitable for liquids that are easy to scale and high-viscosity liquids, as a high concentrator in multiple-effect evaporation devices.

Forced circulation evaporator is very suitable for use as a crystallization evaporator for salt solution.
