As shown in fig. 1, the industrial waste heat recovery heat pump system mainly comprises an absorber, a heat exchanger, a steam generator, a condenser, a molten salt storage tank, an evaporator, a heat pump unit and a plate heat exchanger. The method comprises the following steps that external low-grade waste heat water enters a tube pass of an evaporator, an inlet of the evaporator is connected with a condensed water outlet of a condenser through a pipeline, an outlet of the evaporator is connected with a heat source inlet of an absorber through a steam pipeline, the absorber, a heat exchanger and a steam generator are connected through a lithium bromide solution pipeline to form a lithium bromide solution heat exchange loop, and the steam generator is connected with a steam inlet of the condenser through a steam pipeline; the condenser, the plate heat exchanger and the heat pump unit are connected through a heat medium water pipeline to form a heat medium water heat exchange loop; the steam generator is connected with the fused salt storage tank, and fused salt storage tank and heat pump set are connected through energy input pipeline, and the fused salt storage tank is the drive heat source that provides of lithium bromide solution among the steam generator.
Condensed water from the condenser enters the evaporator after being cooled. In the evaporator, the condensed water absorbs heat from the low-grade waste heat water outside under negative pressure and evaporates into steam. The vapor reaches the absorber under the action of negative pressure, the lithium bromide concentrated solution from the heat exchanger absorbs the vapor from the evaporator in the absorber to become lithium bromide dilute solution, and meanwhile, the heat generated in the absorption process is taken away by cooling water.
The lithium bromide dilute solution enters a heat exchanger to exchange heat with lithium bromide concentrated solution regenerated by a steam generator and then enters the steam generator for regeneration; high-temperature and high-pressure steam from a molten salt storage tank is used as a driving heat source to heat the lithium bromide dilute solution, the lithium bromide dilute solution absorbs a thermal cycle working medium to condense and release latent heat of vaporization, the lithium bromide dilute solution evaporates out the steam, is concentrated and then is pumped into a heat exchanger to exchange heat with the lithium bromide dilute solution from the absorber, and then enters the absorber to complete circulation. And the heat cycle working medium after heat exchange flows out of the steam generator, enters a molten salt storage tank to absorb heat and is converted into high-temperature and high-pressure steam, and then flows back into the steam generator to complete the cycle.
The vapor separated from the vapor generator enters a condenser, is cooled by the heating medium water in the condenser, and is condensed to release latent heat of vaporization. The temperature of the heat medium water from the plate heat exchanger is raised by 10 ℃ after absorbing latent heat of vaporization released by condensation of water vapor in the condenser, the heat medium water preheated by the condenser enters a heat pump unit, the heat pump unit heats the heat medium water and then introduces the heated heat medium water into a shell pass inlet of the plate heat exchanger, and the heated heat medium water heats backwater of the heat network in the plate heat exchanger to a set value and then is output for users to use.
