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

Abstract

The invention discloses a turboset condenser. The turboset condenser comprises a shell; a front water chamber, a heat exchange chamber and a back water chamber are arranged in the shell; the heat exchange chamber is divided into a condensation area at the upper part and a cooling area at the lower part by a partition separation plate in the up-down direction; the condensation area and the coolingarea communicate through a drainage channel in the partition separation plate; the cooling area is provided with a dewatering outlet; a heat exchange structure is arranged in the cooling area; and multiple baffle plates for baffle control of a dewatering runner between the drainage channel in the partition separation plate and the dewatering outlet are arranged in the cooling area. The turboset condenser effectively, stably and reliably integrates the functions of condensation and cooling, can be applied to a turboset to reduce the place and equipment investment of the turboset, facilitates reduction of the operation cost of the turboset, and is excellent in economy.

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...
