Abstract

The invention relates to a combined power and refrigeration cycle system of an absorption steam turbine, which comprises a steam turbine, an evaporator, an absorber and a generator. The steam outlet of the evaporator is communicated with the steam inlet of the absorber. The dilute solution outlet pipe of the absorber is communicated with the solution inlet of a water pump. The water pump pressurizes the dilute solution and delivers the dilute solution to the solution inlet of the generator. The concentrated solution outlet of the generator is communicated with the solution inlet of the absorber after being throttled. A waste heat pipe is communicated with the heat inlet of the heat exchanger of the generator supplies heat to the generator. The steam outlet of the generator is communicated with the steam inlet of the steam turbine. The steam turbine does work. The exhaust port of the steam turbine is communicated with the inlet of the evaporator sequentially through a condenser and a throttle valve. The invention has the advantages that the waste heat is used for generating power which is used as power compensation and the power supplied by the grid is reduced; a great quantity of refrigeration energy can be provided for cooling in factories, the electric energy used for refrigeration in the factories is reduced, the double benefits are obtained, the environment is protected and the energy is saved; and the implementation cost is low, the effect is obvious and the popularization and the implementation are greatly facilitated.

Description

1. Technical Field:

[0001] The invention relates to a waste heat utilization technology, in particular to an absorption steam turbine power-cooling mixed circulation system. 2. Background technology:

[0002] There are a large number of heat sources or waste heat less than 150℃ in our society. This part of heat is not economically economical for power generation, and its thermal coefficient is low for cooling, which is economically unsatisfactory. Most of it is discharged into the environment. Cause thermal pollution to the environment. For example, when a chemical fertilizer plant produces synthetic ammonia, a large amount of waste heat of 150°C is discharged into the environment. At the same time, the chemical fertilizer plant requires a large amount of electricity and cooling. The waste of energy and the ineffective use of energy have become obstacles to the further development of enterprises. 3. Summary of the invention:

[0003] The invention overcomes the shortcomings of th...
