Problems solved by technology

The existence of the heat transfer link affects the increase of the waste heat temperature, which is unfavorable for the application of the second type of absorption heat pump; the installation of the evaporator increases the investment of the device and increases the flow link.
[0003] In some special occasions where there is a large amount of low-temperature waste heat, such as a steam power cycle device, the waste heat exists in the state of low-temperature and low-pressure steam (such as exhaust steam at the outlet of a steam turbine), and the amount is large and the temperature is low. The traditional closed-type second-type absorption is adopted. Heat pumps are used to utilize these waste heat. More heat transfer links are very unfavorable to increase the temperature of waste heat, which also makes the equipment huge and the investment increased.

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] figure 1 Shown is the structure and process of the single-stage open type II absorption heat pump system in which exhaust steam enters the generator and absorber respectively, and the waste heat heats up by itself. Structurally, this type of heat pump system is mainly composed of absorber 1, generator 2, and condenser 3, and the evaporator in the second type of closed absorption heat pump system is omitted. Part of the waste heat steam enters the generator 2 to heat the dilute solution from the absorber to generate refrigerant steam; another part of the waste heat steam enters the absorber 1 to be absorbed by the concentrated solution from the generator 2. The solution from the absorber 1 enters the generator 2, where it is heated by waste heat steam, releases refrigerant vapor and enters the condenser 3 to be condensed into a liquid state by ...

Abstract

This invention provides a kind of open-type the second group absorption heat pump, which belongs to the low temperature waste heat-reusing field of heat supply project. Its single-stage heat pump includes absorber, generator and condenser. The two-stage and multi-stage heat pump has additional absorb-evaporator; one part of waste heat steam is directly absorbed into absorber or absorb-evaporator and used as refrigerant steam for solution absorbing process, the other part diverts and completes the heating process of dilute solution through generator. The waste heat steam turns to condensed water after releasing heat. The condensed water directly returns to the original position after applying pressure-by-pressure increasing pump or after absorbing heat and increasing temperature in absorber. The absorber absorbs steam or refrigerant steam. It releases heat and completes heating to the condensed water or outer fluid. This invention simplifies the equipment and process. It reduces the heat transferring process and improves heat pump technological parameter.

Description

technical field [0001] The invention belongs to the field of low-temperature waste heat utilization energy-saving equipment and engineering technology. Background technique [0002] Using absorption heat pump technology for waste heat utilization is an effective means, which has relatively good energy saving, environmental protection and economic benefits. In the energy-saving work, among the absorption heat pumps that play a more critical role, the second type of absorption heat pump has a special status. It is generally composed of a generator, a condenser, an evaporator and an absorber. The heat pump cycle is completed inside the heat pump; when there is waste heat available, no matter what the characteristics of the waste heat are, it is necessary to heat the refrigerant medium inside the heat pump through the evaporator to make it evaporate, and the evaporated refrigerant medium enters the absorber and is taken from The concentrated solution of the generator is absorbe...
