Description

Back-heating type generation-absorption system and type II high-temperature 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 through 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 corresponding corresponding performance indexs.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 when 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 back-heating type 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 unit.
Summary of the invention:
Main purpose of the present invention is at first to provide solution series to loop back hot type generation-absorption system and solution independent loops back-heating type generation-absorption system; In these two kinds of back-heating type generation-absorption systems, increase different members then, obtain having second class absorption heat pump of high-temperature heat supply end---be type II high-temperature absorption heat pump.
1. one of back-heating type generation-absorption system among the present invention is such: to be applied to second class absorption heat pump have the concentrated solution pipeline to be communicated with absorber, absorber by generator to have the weak solution pipeline to be communicated with generator, generator driving thermal medium pipeline and external communications also to be arranged respectively and the refrigerant vapour pipeline is arranged and external communications, absorber also have heated medium pipeline and external communications respectively and the refrigerant vapour pipeline arranged and the formed generation-absorption system of external communications through solution heat exchanger through solution pump and solution heat exchanger; Introduce flash vessel, second absorber, second solution pump, the 3rd solution pump and second solution heat exchanger; And adopt the solution series circulation---with generator have the concentrated solution pipeline through solution pump and solution heat exchanger be communicated with absorber change into generator have the concentrated solution pipeline through solution pump and solution heat exchanger be communicated with successively absorber and flash vessel, again by flash vessel establish concentrated solution pipeline warp second solution pump, second solution heat exchanger is communicated with second absorber and second absorber has weak solution pipeline warp second solution heat exchanger, the 3rd solution pump connection absorber again; Absorber, second absorber have the refrigerant vapour pipeline respectively and heated medium pipeline and external communications are arranged, and generator, flash vessel have refrigerant vapour pipeline and external communications respectively; Driving weak solution that thermal medium adds heater discharges behind the refrigerant vapour concentrated solution and flows through and get into flash vessel again after absorber, the heat absorbing part vaporization and discharge refrigerant vapour; Concentrated solution after concentration further improves gets into second absorber, absorbs from the refrigerant vapour outside the system and emits the demand for heat that elevated temperature heat satisfies the heated medium second stage through second solution pump and second solution heat exchanger from flash vessel; Solution after the concentration reduction gets into absorber, absorbs from the refrigerant vapour outside the system and also heat the solution of the absorber of flowing through and satisfy the demand for heat of heated medium phase I through second solution heat exchanger and the 3rd solution pump; Solution after concentration further reduces is got back to generator through solution heat exchanger and is heated and discharges refrigerant vapour, obtains solution series and loops back hot type generation-absorption system; 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.
