Rich steam vacuum pump applications - in the industry

vacuum pump has a very wide range of applications, today will give you introduce rich steam vacuum pump application in industry.

1。 Vacuum concentration ( Single and double) Continuous or batch

traditional Chinese medicine, drinks, etc.

2. Vacuum crystallization ( Single, double, triple effect) Continuous or batch

industrial salt, solid beverage such as

3. Steam turbine

expanding power

rich steamed multi-effect process characteristics of

a mother liquor evaporation no steam condensation, heat brought into effect; 1 ton hot water evaporation minimum required steam for 1 ton; Double effect of halving powered steam; But

,

2 effect evaporation temperature decreases, at least 20 degrees i. e. effect also need vacuum as fluid power for heat sensitive medium, vacuum needs to further improve

in evaporation in production, the output of the secondary steam, and production of a large number of latent heat, so should be recycled to use, if the access to the secondary steam heating of the evaporator chamber, as long as the operating pressure and solution boiling point lower than the original operating pressure and the boiling point of the evaporator, into the secondary steam heating effect, still called multi-effect evaporation. Evaporation temperature drops, the pressure automatically assigned, step by step down.

when the material liquid flow through the pressure difference, do not need to pump.

is shown in the figure and flow method, the flow of the solution and steam in the same direction, namely by the end of the first order effect to effect, and reflux method, the advection method.

in the process of the condenser type

tube shell type indirect cooling

the efficiency is low, but the tolerance is relatively high dirt; Often require higher evaporation temperature or greater heat transfer area; Still need regular cleaning of pollutants, increased the complexity of deconstruction; The higher the evaporation temperature, the greater the risk of fouling in heat exchange surface;

plate indirect cooling

efficiency is higher, but the dirt tolerance level is low; Constrained by the cost limit, often low evaporation temperature is limited; Regular cleaning of pollutants, the gasket between the sheets is consumable materials; Scale of board change is fatal shortcomings; Direct cooling

heat transfer occurs in the liquid phase, the highest efficiency. The highest cost, needs to design liquid circulation and condensate drain system; Loop line design of solid, liquid filter, the pollutants with condensed water discharge online; Is not sensitive to scale;

vacuum pump system solutions

vacuum water pump without additional sewage produced. Maximum direct cooling off condensable vapor phase. Booster water pump for further remove the condensable vapor phase conditions; And reduce exhaust vacuum pump vacuum degree requirements. Main processing system leak air exhaust vacuum water pump and condenser. Exhaust vacuum pump can choose dry vacuum pump.
