Description

A kind of two-stage first class absorption heat pump
Technical field
The invention belongs to low temperature exhaust heat utilization and absorption heat pump technical field.
Background technology
First kind absorption heat pump is to utilize heat energy to realize the efficient energy-saving device that low temperature exhaust heat utilizes as driving force, is widely used in industry, civilian central heating and cogenerations such as petroleum and petrochemical industry, smelting, iron and steel.Having higher heat supply temperature, simple set structure and higher performance index is the guide that source pump is optimized design.Be the driving heat source of utilizing low temperature more or the heat that higher temperature is provided, people have developed two-stage and the multistage absorption heat pump meets the demands, but traditional two-stage and multi-stage absorption refrigeration machine form are single, complex structure, cost are high, have limited the application of first kind absorption heat pump.Therefore adopt the heat supply temperature of simple as far as possible structure and Geng Gao will enrich the type of two-stage first class absorption heat pump unit and help the further popularization and the use of absorption heat pump, for bigger contribution is made in the energy-saving and emission-reduction of China.
Summary of the invention
Main purpose of the present invention provides a kind of two-stage first class absorption heat pump unit.
1. a kind of two-stage first class absorption heat pump unit provided by the present invention, it is characterized in that by generator, absorber, evaporimeter, condenser, choke valve, solution pump and solution heat exchanger form single-action first kind absorption type heat pump assembly---the refrigerant vapour of evaporator outlet enters absorber, quilt is from generator, the concentrated solution that enters absorber through solution heat exchanger absorbs, enter generator through solution pump and solution heat exchanger again after becoming weak solution, again discharging refrigerant vapour under the effect of driving heat source provides to condenser, condensed refrigerant vapour becomes cryogen liquid, cryogen liquid enters evaporimeter after the choke valve throttling, again becoming refrigerant vapour after the heat of absorption waste heat medium provides to absorber, absorber and condenser have heated medium pipeline and external communications respectively, generator has the thermal medium pipeline of driving and external communications, evaporimeter have surplus heat medium pipeline and external communications---the basis on, increase newly-increased parts---newly-increased cryogen liquid pump or newly-increased choke valve, newly-increased solution pump, newly-increased absorber and newly-increased solution heat exchanger, the refrigerant vapour pipeline that evaporator outlet is communicated with absorber changes the newly-increased absorber of connection into, or flash-pot is set up the cryogen liquid pipeline through newly-increased cryogen liquid pump, or self cooling condenser is set up the cryogen liquid pipeline through the newly-increased absorber of newly-increased choke valve connection, newly-increased absorber also has refrigerant vapour pipeline connection absorber, set up the concentrated solution pipeline from generator and be communicated with newly-increased absorber through newly-increased solution heat exchanger, newly-increased certainly absorber is set up the weak solution pipeline through newly-increased solution pump, newly-increased solution heat exchanger is communicated with generator; The generator exports concentrated solution enters newly-increased absorber, absorb the refrigerant vapour of flash-pot, heat release in or come flash-pot through newly-increased cryogen liquid pump, or offer another road cryogen liquid of newly-increased absorber through newly-increased choke valve from condenser, make it to be vaporizated into saturated vapor and provide to absorber, the weak solution that obtains is got back to generator behind newly-increased solution pump and newly-increased solution heat exchanger, again discharging refrigerant vapour under the effect of driving heat source provides to condenser, the cryogen liquid that refrigerant vapour condensation and heat release in condenser form behind heated medium or enter evaporimeter through the choke valve throttling and provide to newly-increased absorber by newly-increased cryogen liquid pump again, or after newly-increased choke valve throttling, provide to newly-increased absorber, finish single-action two-stage absorption heat pump cycle.
