Embodiment Construction

[0015] Attached below figure 1 The present invention is described in further detail with specific embodiments:

[0016] A power plant condensation heat recovery heating system using circulating cooling water as heating network water, such as figure 1 As shown, it includes a steam pipeline 1 , a circulating cooling water pipeline 2 , a steam extraction pipeline 3 , a spare circulating cooling water pipeline 4 and a heating pipeline 5 .

[0017] The steam in the steam pipeline 1 is sent to the steam turbine 11 to do work, and the exhaust steam discharged from the steam turbine 11 is sent to the condenser 12, and the exhaust steam passes through the condenser 12 to transfer heat energy to the cooling water in the circulating cooling water pipeline 2 Then condense into water and discharge.

[0018] In the circulating cooling water pipeline 2, the return water from the heating network enters the circulating cooling water pipeline 2 as cooling water after passing through the absor...

Abstract

The invention relates to a heat recovery system, and discloses a power plant condensation heat recovery heat supply system taking circular cooling water as heat supply network water. The power plant condensation heat recovery heat supply system comprises a steam pipeline and a heat supply pipeline, wherein the heat supplying pipeline is used for absorbing heat through an absorption heat pump; and water of which the temperature rises enters a primary heat supply network. The power plant condensation heat recovery heat supply system is characterized by further comprising a circular cooling water pipeline, wherein heat supply network return water enters the circular cooling water pipeline for serving as cooling water after heat release through the absorption heat pump; and the circular cooling water pipeline is used for making cooling water in a circular cooling water pond enter a condenser through a circular cooling water pump, and is communicated with a heat supply pipeline. Through the heat-exchanging way of the absorption heat pump, condensation heat recovery is realized, condensation heat of a power plant and residual heat in circular cooling water are recovered, circular cooling water is taken as heat supply network water, water energy is saved, and heat energy consumption is lowered; and the power plant condensation heat recovery heat supply system has the advantages of high heat energy recovery utilization ratio, energy saving, emission reduction and the like.

Description

technical field [0001] The invention relates to a power plant waste heat recovery device, in particular to a power plant condensation heat recovery heating system. Background technique [0002] The condensation heat of thermal power plants is discharged into the atmosphere through cooling towers or air-cooled islands, resulting in huge heat loss, which is the main reason for the low efficiency of energy use in thermal power plants. It not only causes a lot of waste of energy and water or electricity, but also seriously pollutes the atmosphere. . The evacuation of condensation heat in thermal power plants is a common problem in our country and even in the world. It is a waste and helpless. However, with the development of heat pump technology, especially the advent of large-scale high-temperature water source heat pumps, it will become possible to recover the condensed waste heat of generating units. Contents of the invention [0003] Aiming at the problem that condensati...
