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

Example Embodiment

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

[0021] figure 1 Shown is the structure and flow of a single-stage open type second type absorption heat pump system where exhaust steam enters the generator and absorber separately, and the waste heat is heated by itself. Structurally, this type of heat pump system is mainly composed of the absorber 1, the generator 2, and the condenser 3, eliminating the need for the evaporator in the closed type second absorption heat pump system. 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 and is absorbed by the concentrated solution from the generator 2. The solution from the absorber 1 enters the generator 2 and is heated by the waste heat steam in the generator 2 to release the refrigerant vapor into the condenser 3 and be condensed into...

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...
