Thermal-energy stepwise multi-use solution concentrating-regeneration device

Abstract

The invention discloses a solution concentration regeneration equipment for heat energy reuse in step, comprising steam kettle, heat exchanging system, peripheral pipe system and electric control system. The steam kettle comprises part in high-temperature zone, part in middle zone and part in condensing zone. Said part in the middle zone comprises outer wall, inlet port for dilute solution, outlet port for concentrated solution, installing port for inductor, solvent outlet port, vent and dissepiment between cavities. Said dissepiment between cavities comprises heat exchanging rib in evaporating room, middle plate of dissepiment between cavities and heat exchanging rib of condensing room. The invention can be widely applied in chemical condensing process, generator of air-conditioner with lithium bromide and so on. It can save energy and water resource greatly. It can decrease operation cost and compress equipment space. It is provided with huge environmental benefit and economical effect.

Description

technical field [0001] The invention relates to the fields of solution concentration and regeneration, chemical extraction, seawater desalination, etc., and in particular, relates to a thermal energy cascade reuse solution concentration regeneration equipment. Background technique [0002] The invention can replace the generator of the lithium bromide air conditioner and the multi-effect evaporator in the pharmaceutical production industry. The existing double-effect lithium bromide absorption refrigerator has two generators of high pressure and low pressure, and the diluted lithium bromide absorbent solution first arrives at the high pressure generator, and is heated by steam at a higher temperature in the high pressure generator coil; in the high pressure generator The refrigerant vapor generated in the low-pressure generator is used as the heat source of the low-pressure generator to heat the intermediate solution of the low-pressure generator, so that the thermal energy ...

AI Technical Summary

Problems solved by technology

They all use the tube-type heat exchange principle and the method of pumping steam to maintain the air pressure difference, resulting in a large temperature difference loss, and because the energy-saving efficiency decreases rapidly with the increase in the number of effects, it ultimately leads to the inability to effectively increase the number of uses

In addition, because each effect (one use) has an independent irrigation, the volume of the whole system is relatively large, and the piping system is complicated, which is not conducive to saving space, nor is it conducive to modular production, and is not suitable for the current industrial production. development trend
