Problems solved by technology

[0007] This leads to some problems: single-unit waste steam waste heat recovery heat supply, exhaust steam recovery is limited, only one exhaust steam, the energy-saving potential of exhaust steam waste heat of the entire thermal power plant has not been fully tapped; single-unit exhaust steam waste heat recovery heat supply, two The exhaust steam of each unit is not interconnected
Exhausted steam cannot be recovered, which not only affects the energy saving effect, but also affects the safety of heating
In case the failure occurs in the deep cold season, there will be insufficient heat supply, the temperature in the residents' homes will not meet the requirements, and a heating accident will occur

Embodiment approach 1

[0017] Implementation mode 1: dual-machine interconnection pre-condenser waste steam waste heat recovery heating system, such as figure 1 shown.

[0018] The heating system using pre-condenser waste steam waste heat recovery is also called high back pressure system. The unit operates with elevated back pressure, and uses the exhausted steam to directly enter the pre-condenser to heat the return water of the heating network to an appropriate temperature.

[0019] The exhaust steam outlet pipe (3) of the 1# large steam turbine unit and the exhaust steam outlet pipe (4) of the 2# large steam turbine unit are connected to each other, and the exhaust steam (exhaust steam of the low-pressure cylinder) of the two large steam turbine units is integrated to form a large steam turbine unit Exhaust steam leads to the shared pipeline (7). The exhaust steam outlet pipe (3) of the 1# large steam turbine unit and the exhaust steam outlet pipeline (4) of the 2# large steam turbine unit are ...

Embodiment approach 2

[0026] Implementation Mode 2: A heat supply system for recovery of waste heat from waste steam of dual-machine interconnected steam generators, such as figure 2 shown.

[0027] The exhaust steam outlet pipe (3) of the 1# large steam turbine unit and the exhaust steam outlet pipe (4) of the 2# large steam turbine unit are connected to each other, and the exhaust steam (exhaust steam of the low-pressure cylinder) of the two large steam turbine units is integrated to form a large steam turbine unit Exhaust steam leads to the shared pipeline (7). The exhaust steam outlet pipe (3) of the 1# large steam turbine unit and the exhaust steam outlet pipeline (4) of the 2# large steam turbine unit are respectively equipped with exhaust steam pipeline valves (13) and valves (14). The common pipe (7) leading out the exhaust steam of the large steam turbine unit is connected to the steam side of the pre-condenser.

Abstract

The invention provides a multi-machine interconnecting waste steam and waste heat recovery system. The multi-machine interconnecting waste steam and waste heat recovery system comprises a plurality oflarge turbine sets, and the large turbine sets are connected with condensed steam cooling equipment through corresponding waste steam pipelines; waste steam eduction pipelines of the large turbine sets are connected mutually and integrally to form a large turbine set waste steam induction common pipeline; and the large turbine set waste steam induction common pipeline is connected to the steam side of a front condenser, a heat supply network water return pipeline is connected to the water side of the front condenser, and the front condenser is used as a primary heating segment to perform primary heating on heat supply network water return. The waste steam and waste heat recovery energy-saving effect can be improved, and the heat supply safety can be greatly improved at the same time.

Description

technical field [0001] The invention belongs to the field of waste steam waste heat recovery and energy saving in power plants, and in particular relates to a multi-machine interconnection exhaust steam waste heat recovery heating system. Background technique [0002] The exhaust steam of the power plant (that is, the exhaust steam of the low-pressure cylinder of the steam turbine) contains a large latent heat of vaporization. The enthalpy value of the main steam entering the steam turbine is generally 3500kj / kg, and the enthalpy value of the exhaust steam from the low-pressure cylinder of the steam turbine is generally about 2400-2600kj / kg. [0003] At present, exhaust steam in power plants is generally discharged to the atmosphere through cooling equipment (air-cooling island, condenser, air-cooling tower, etc.), the heat is wasted in vain, and it also consumes water and electricity. The energy lost by the power plant through exhaust steam is the cold end loss. The power...
