Problems solved by technology

Therefore, the steam system in the current combined cycle power generation system is relatively complicated. During actual operation, it is found that the efficiency of steam power generation due to low thermal potential is not high, and the consumption of cooling water for the condenser is increased, which increases the workload of construction investment and operation and maintenance. , low thermal potential steam is not the best use for power generation

Embodiment 1

[0020] Example 1, such as figure 1 As shown: the circulation medium in the hot side of the air heat exchanger 1 is air, and the circulation medium in the cold side is water; the steam-type absorption refrigerator 2 uses water as a refrigerant and lithium bromide as an absorbent; the steam-type absorption refrigerator 2 The heat source inlet circulation medium is steam, and the outlet circulation medium is water.

[0021] An air filter 3 is provided on the hot side air intake pipe of the air heat exchanger 1, and the hot side air outlet pipe of the air heat exchanger 1 is connected with an air compressor 8, and the cold side air inlet pipe of the air heat exchanger 1 is The water outlet and the water outlet are respectively connected with the water outlet and the water inlet of the steam-type absorption refrigerator 2 through pipelines;

[0022] A water supply pump 14 is provided on the cooling water outlet pipeline of the steam-type absorption refrigerator 2 , and a condensat...

Embodiment 2

[0029] Other structures of Embodiment 2 are the same as those of Embodiment 1, except that there are two or more air heat exchangers 1 and steam-type absorption refrigerators 2 . The air heat exchangers 1 are connected in parallel, that is, the hot-side air outlets of each air heat exchanger 1 are connected to the gas turbine air compressor 8; they are all separately supplied to the gas turbine air compressor 8, The steam-type absorption refrigerators 2 are connected in parallel, that is to say, each steam-type refrigerator 2 is connected to one or more air heat exchangers 1 separately, supplies water independently, and works independently.

Abstract

The invention discloses an air temperature adjusting system which comprises an air heat exchanger (1). A hot side air inlet pipe of the air heat exchanger (1) is communicated with air, a hot side air outlet pipe of the air heat exchanger (1) is connected with an air compressor (8), and a cold side water inlet and a cold side water outlet of the air heat exchanger (1) are communicated with a cold water inlet and a backwater opening of a steam absorption refrigerator (2) by pipelines respectively. A hot source steam inlet of the steam absorption refrigerator (2) is connected with a waste heat boiler low-pressure steam collecting box (5). A hot source condensation water outlet of the steam absorption refrigerator (2) is connected with a waste heat boiler condensation water inlet (d) of a waste heat boiler (7). The system disclosed by the invention has the advantages of simplicity, low investment and low operation and maintenance cost and can be widely applied to a gas-steam combined cycle power generation technique.

Description

technical field [0001] The invention relates to a temperature regulating system, in particular to an air temperature regulating system. Background technique [0002] In recent years, the gas-steam combined cycle power generation process has been widely used. This process uses natural gas or other combustible gases as fuel, and is mixed with air in the combustion chamber to generate high-temperature, high-pressure gas, which is expanded by a gas turbine. For power generation, the exhaust gas discharged from the gas turbine is led to the waste heat boiler to generate high-temperature and high-pressure steam to drive the steam turbine to do power generation. It is a power generation process that uses energy efficiently and cleanly. [0003] Since the fuel gas needs to be mixed with a large amount of air in the combustion chamber, the operation of the gas turbine is greatly affected by the external atmospheric environment. In actual operation, it is found that the seasonality ha...
