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 is all 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 is all 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, absorber heat-transfer pipe 8), effect through heat-transfer pipe, bromizating the inner loop of lithium absorption heat pump and the energy of outer loop two systems exchanges, reach the purpose of Heat Pump exchange.
The utility model content
The purpose of this utility model is more to optimize absorption heat pump and external system in the past, improves the granting temperature difference of waste heat thermal source, obtains more waste heat heat, and system is oversimplified, and saves volume and the manufacturing cost of operating cost, reduction heat pump.
the purpose of this utility model is achieved in that 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 flash chamber, flash chamber and absorber are in same chamber, 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.In waste heat source heat exchanger pipeline, heated hot water enters the flash chamber shwoot.
The absorption energy of the utility model reclaims device for improving quality, the water access flash chamber that described condenser condenses becomes.
Medium in 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 device for improving quality, and the water after 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 organ pipe and takes out of, supplies with and uses with thermal field, the temperature that the temperature that obtains is sent into higher than the waste heat source heat exchanger.The weak solution that has absorbed was advanced solution pump and was carried, and 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, supplied the water yield of flash distillation, and device is circulation constantly.Low-grade thermal source is recycled utilization, and exports the place utilization of high-grade heat supply, has realized the purpose of energy-saving and emission-reduction.
The kind of refrigeration cycle of doing of the present utility model, the water after flash chamber cooling as low-temperature receiver for awkward silence at a meeting.
The beneficial effects of the utility model are:
A kind of absorption energy of the utility model 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's evaporimeter in service position is also replaced by the remaining hot water circulating pump in 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.
