A steam turbine condenser

Abstract

The invention discloses a condenser of a steam turbine unit, which comprises a casing, the casing has a front water chamber, a heat exchange chamber and a rear water chamber, and the heat exchange chamber is divided into upper and lower parts by partition plates in the up and down direction. The condensation zone and the lower cooling zone, the condensation zone and the cooling zone are communicated with the drainage channel at the partition plate, the cooling zone is provided with a drain outlet, the cooling zone is provided with a heat exchange structure, and the cooling A plurality of baffles are provided in the zone to control the baffle flow of the drainage channel between the drainage channel at the partition plate and the drainage outlet. The invention effectively, stably and reliably integrates the functions of condensation and cooling, and its application in the steam turbine unit can help reduce the site and equipment investment of the steam turbine unit, thereby reducing the operation cost of the steam turbine unit, and has good economical efficiency.

Description

technical field [0001] The invention relates to a condenser of a steam turbine unit. Background technique [0002] Steam is the working medium of the steam turbine. In the steam cycle process of the steam turbine unit, the steam discharged from the steam turbine needs to be condensed into water, cooled to the required temperature, and then refined. It can be seen that the steam cycle process of the steam turbine unit includes condensation, cooling, finishing and other processes. [0003] As an important component of the steam turbine unit, the condenser is used to condense the exhaust steam of the steam turbine into water by heat exchange. The existing condenser only has the function of condensing the exhaust steam of the steam turbine into water, and does not have the function of cooling the condensed water, which makes the condensed water discharged through the condenser unable to be directly discharged into the hydrophobic refinery because the temperature does not meet t...

AI Technical Summary

Problems solved by technology

This is especially common with high back pressure steam turbine units. Specifically, in order to realize energy saving and consumption reduction of power plants and increase economic benefits, high back pressure steam turbine units usually use the condenser as the return water heating of the heat network, that is, through the condenser to The steam exhausted by the steam turbine is used to heat the hot water in the heating network to a predetermined temperature, so as to realize the technical purpose of reusing the waste heat of the steam exhausted by the steam turbine; there is no doubt that this will cause the condensed water condensed by the condenser The temperature is too high to meet the technical requirements of the hydrophobic finishing system. It is necessary to install a hydrophobic cooler between the condenser and the hydrophobic finishing system so that the condensed water can be cooled according to the technical requirements before entering the hydrophobic finishing system. Cooling treatment

[0004] This technology of cooling the condensed water in the condenser by means of the intermediate hydrophobic cooler can make the cooled hydrophobic effectively meet the technical requirements of the hydrophobic fine treatment system, but it will be reduced due to the increase in equipment. Affects the spatial layout of the steam turbine unit, resulting in a large investment in site and equipment, resulting in high operating costs and insufficient economic efficiency of the steam turbine unit
