Description
Technical field
The present invention relates to a kind of absorption energy and reclaim device for improving quality.Belong to the heat exchanger technical field.
Background technology
General heat exchanger and system have: water---water heat exchanger, air---water heat exchanger, can carry out heat exchange by the temperature difference that two media or fluid exist, and regaining heat, the required medium temperature that the heat exchange of this heat exchanger institute obtains all is lower than heat source temperature.Another kind of technology is heat pump techniques, by effect and the heat exchange of driving-energy, can obtain the medium temperature higher than waste heat source.Heat pump generally has compression heat pump and the absorption heat pump take heat energy as power take electricity as power.Absorption heat pump commonly used is take lithium-bromide solution as absorbent, take heat energy as power.Lithium bromide absorption type heat pump is by generator 3, condenser 1, evaporimeter 5, absorber 7, solution heat exchanger 11, waste heat source heat exchanger 12, refrigerant cycle pump 9, solution pump 10, remaining hot water circulating pump 13 and system pipeline form, its generator, condenser, evaporimeter, absorber all is again single heat exchanger, each position all is furnished with heat-transfer pipe (condenser heat-transfer pipe 2, generator heat-transfer pipe 4, heat-transfer pipe of evaporator 6, absorber heat-transfer pipe 8), effect through heat-transfer pipe, bromizate the inner loop of lithium absorption heat pump and the energy of two systems of outer loop and exchange, reach the purpose of Heat Pump exchange.
Summary of the invention
The object of the invention is to more optimize in the past absorption heat pump and external system, improve the granting temperature difference of waste heat thermal source, obtain more waste heat heat, system is oversimplified, save volume and the manufacturing cost of operating cost, reduction heat pump.
The object of the present invention is achieved like this: a kind of absorption energy reclaims device for improving quality, comprise generator, condenser, absorber, solution heat exchanger, the waste heat source heat exchanger, solution pump and remaining hot water circulating pump, described generator, condenser and absorber are respectively arranged with the condenser heat-transfer pipe, generator heat-transfer pipe and absorber heat-transfer pipe, it is characterized in that: described device also includes flash chamber, heat-transfer pipe is not set in the flash chamber, flash chamber and absorber are in same chamber, and the import and export pipeline of remaining hot water circulating pump is connected the system pipeline of waste heat source heat exchanger with flash chamber.Heated hot water enters the flash chamber shwoot in the waste heat source heat exchanger pipeline.
The absorption energy of the present invention reclaims device for improving quality, the water access flash chamber that described condenser condenses becomes.
Medium in the described waste heat source heat exchanger pipeline is water, water obtains the heat intensification in the waste heat source heat exchanger after, directly enters absorption energy and reclaims shwoot cooling in the device for improving quality, and the water after the cooling is sent to waste heat source heat exchanger draw heat again through pump.The water vapour that shwoot goes out is absorbed by lithium-bromide solution, the lithium-bromide solution concentration that absorbs water vapour is thinning, the heat that absorption process produces is absorbed the cooling water that flows in the organ pipe and takes out of, supplies with and uses with thermal field, and the temperature that obtains is higher than the temperature that the waste heat source heat exchanger is sent into.The weak solution that has absorbed was advanced the solution pump conveying, entered generator after solution heat exchanger heats up, and was produced water vapour by the external heat source heating, and water vapour enters condenser condenses Cheng Shui, and solidifying water flows into the flash distillation position again, supplies the water yield of flash distillation, and device constantly circulates.Low-grade thermal source is recycled utilization, and exports high-grade heat supply place and utilize, and has realized the purpose of energy-saving and emission-reduction.
The kind of refrigeration cycle of doing of the present invention, the water after flash chamber cooling as low-temperature receiver for awkward silence at a meeting.
The invention has the beneficial effects as follows:
A kind of absorption energy of the present invention reclaims device for improving quality, has removed heat exchange pipe of evaporator in device, and the external system heat exchange obtains the water of heat, and directly flash distillation in evaporimeter is removed draw heat after the reduction temperature again.With lithium bromide absorption type heat pump and external system contrast in the past, owing to having removed heat-transfer pipe of evaporator, thereby also eliminated heat transfer temperature difference, can obtain more waste heat heat, water as refrigerant circulating pump at system evaporimeter in service position is also replaced by the remaining hot water circulating pump in the system, reduced the operation power consumption of a water pump, made system more energy-conservation.Evaporimeter has removed heat exchanger tube, only need stay the space of some flash distillations, and the volume of unit and manufacturing cost all can descend greatly.
