Double-effect external heating from outer circulation evaporation system

First, the use of equipment:

Double-effect external heating The external-circulation condensation evaporation system is suitable for the concentration of liquids such as traditional Chinese medicine, western medicine, glucose, starch, monosodium glutamate, dairy products, and chemical industries, and is particularly suitable for cryogenic vacuum concentration of heat-sensitive materials.

Second, the structure and characteristics:

The system equipment is mainly composed of one or two effect heaters and one or two effect evaporators, condensers, connecting pipes, valve gauges, vacuum pumping devices, etc. The secondary steam generated by one effect is used as a secondary heat source.

1. Energy-saving benefits: According to SJN-1000 calculation, about 3,500 tons of steam will be saved in a year, saving about 90,000 tons of cooling water, saving about 80,000 degrees of electricity, equivalent to RMB 10-15 million. (Comparison with single effect).

   2. The concentrator adopts external heating natural circulation type and vacuum negative pressure evaporation method. It has the advantages of high evaporation speed and large concentration ratio, which can reach 1.2-1.35 (general Chinese medicine extract).

   3. The concentrator uses two effects to condense and evaporate at the same time. The second steam is used, which saves a lot of energy consumption. The energy consumption is reduced by 50% compared with the single-effect concentrator. Less than one year, the concentrator can be recovered from the energy-saving fee. Evaporator's full investment.

   4. Multi-functional operation features: (1) The recoverable alcohol concentration is about 80%; (2) The single-effect and two-effect evaporator can be used repeatedly; (3) The batch can be fed continuously.

   Third, specifications and technical parameters:
