Description

A kind of regenerative generation-absorption system and high temperature modification second class absorption heat pump
Technical field:
The invention belongs to low temperature exhaust heat utilization and technical field of heat pumps.
Background technology:
Adopt the absorption heat pump technology to carry out UTILIZATION OF VESIDUAL HEAT IN and have reasonable energy-saving and environmental protection and economic benefit, its prerequisite is that heat pump can rise to heat more than the level of user's request from waste heat supply temperature.Promote the heat supply temperature of heat pump, the utilization rate of utilizing the residual heat resources of low temperature more and improving residual heat resources is the main direction that people make great efforts.
For heat supply temperature and the performance index that makes absorption heat pump is improved, people had obtained the unit of different effect numbers and different progression before this by research, adopt to increase heat supply end, increase that methods such as heat supply flow process carry out different heat pump flowsheets compoundly obtain more careful effect number and progression, their correspondences corresponding performance index.But, the unit of these single effect numbers or single progression all exists certain deficiency mostly---and the single effect number that each is concrete or the unit of progression are just worked as at having proper working parameters and performance index under the specific situation, such as a single two-stage unit, its heat supply temperature height but performance index is low.
From the unit internal process, the key that improves the second class absorption heat pump heat supply temperature is to improve the solution concentration of absorber outlet, just will improve the solution concentration of generator exports.The backheat principle is applied to the generation-absorption process of solution, sets up regenerative generation-absorption system, combine based on this and with the source pump of different effect numbers, different progression, can improve the heat supply temperature of corresponding unit; Simultaneously, adopt backheat also can realize the two ends or the multiterminal heat supply of second class absorption heat pump, this is useful for the performance index that improves the level group.
Summary of the invention:
Main purpose of the present invention is that a kind of regenerative generation-absorption system will at first be provided, on this regenerative generation-absorption system, increase different members then, obtain having second class absorption heat pump of high-temperature heat supply end---be high temperature modification second class absorption heat pump.
A kind of regenerative generation-absorption system among the present invention is such: structurally, the concentrated solution pipeline is arranged through solution pump at what be applied to second class absorption heat pump by generator, solution heat exchanger is communicated with absorber, absorber has the weak solution pipeline to be communicated with generator through solution heat exchanger, also have surplus heat respectively medium or drive thermal medium pipeline and external communications and refrigerant vapour pipeline and external communications are arranged of generator, absorber also has heated medium pipeline and external communications respectively and refrigerant vapour pipeline and the formed generation-absorption system of external communications is arranged, introduce flash vessel, second absorber, second solution pump, the 3rd solution pump and second solution heat exchanger, form regenerative generation-absorption system---generator there is the concentrated solution pipeline through solution pump, solution heat exchanger connection absorber changes generator into has the concentrated solution pipeline through solution pump, solution heat exchanger is communicated with absorber and flash vessel successively, flash vessel is established the concentrated solution pipeline again through second solution pump, second solution heat exchanger is communicated with second absorber and second absorber has the weak solution pipeline again through second solution heat exchanger, the 3rd solution pump is communicated with absorber, absorber, second absorber has the refrigerant vapour pipeline respectively and heated medium pipeline and external communications, generator is arranged, flash vessel has refrigerant vapour pipeline and external communications respectively; On flow process, waste heat medium or drive weak solution that thermal medium adds heater and discharge behind the refrigerant vapour concentrated solution and flow through and enter the flash vessel step-down again after the absorber heat absorption and discharge refrigerant vapour, concentrated solution after concentration further improves from flash vessel through second solution pump, second solution heat exchanger enters second absorber and absorbs from the outer refrigerant vapour of system and emit the demand for heat that elevated temperature heat satisfies the heated medium second stage, solution after concentration reduces from second absorber through second solution heat exchanger, the 3rd solution pump enter absorber absorb from the outer refrigerant vapour of system and respectively heating flow through absorber solution and satisfy the demand for heat of heated medium phase I, the solution after concentration further reduces is got back to generator through solution heat exchanger and is heated and discharges refrigerant vapour; When absorber did not have heated medium pipeline and external communications, the heat that absorber absorption refrigerant vapour is emitted only was used to heat the solution of the absorber of flowing through.
The outer cryogen steam heat release of absorber system is in the solution of the absorber of flowing through, in second a concrete and complete kind absorption type unit, refrigerant vapour and solution all belong to the working media of unit---working medium, the heat release that enters the solution absorption refrigerant vapour of absorber is the heat release of working medium, and the heat absorption of the solution of the absorber of flowing through is the heat absorption of working medium, this process just is called backheat on term so---and utilize the heat release of a certain process working medium to satisfy the heat absorption of working medium in another process in the circulation, the generation-absorption system among the present invention then is a regenerative generation-absorption system.According to the warm eventually height of heated medium demand heating, need correspondingly adjust the amplitude of solution released vapour in flash vessel, this depend on thermic load that the solution of the absorber of flowing through obtains what---it is few more to load, the refrigerant vapour that solution flashes off in flash vessel is just few more, enter just few more that the solution concentration of second absorber increases, the amplitude that the temperature eventually of heated medium promotes is also just low more.In addition, under the consistent situation of the refrigerant vapour that absorber and second absorber absorb, the heat release of the second absorber pairing performance index of loading approaches the pairing performance index of absorber heat release more, and this makes can have higher performance index when realizing high-temperature heat supply in conjunction with second class absorption heat pump of the present invention within the specific limits.
