Small waste heat recovery system

Small waste heat recovery system：

The technology makes use of the low-grade waste heat (80 °C ~ 130 °C) in industrial production to recover and utilize it. The cold source above-25 °C can be made by the single-stage device, and the true low-temperature waste heat can be efficiently utilized by cop45% ~ 65%；The whole system has small power drive parts, stable work, easy to operate, and low maintenance cost, high security;Using organic mixed solution as refrigerant, this technology can effectively alleviate a series of environmental problems caused by the use of freon, reduce greenhouse gas emissions, and realize a new concept of green energy.

Features：

1.Energy saving;

2.Saving electricity;

3.Pollution-free;

4.Stable and reliable operation, simple operation and easy adjustment;

5.Land occupation province;

6.Easy maintenance;

7.Low noise.

Technical Parameters：

Process flow：

The vapor refrigerant (ammonia) is separated from the steam condensing water heating generator, and then evaporates to condense, forming liquid ammonia which is stored temporarily in the buffer tank. After decompression, it is sent into the evaporator for evaporating and absorbing heat,so that the temperature of the refrigerant (glycol aqueous solution) in the tube side of the evaporator is reduced to -20.2℃. The poor solution resolved by the generator is sent into the absorber to be mixed with the low pressure ammonia gas generated by heat exchange through the evaporator, and reduced to a rich solution, which is pumped to the generator for circulating refrigeration.
