The condenser water charging system efficiently sprays atomising device
[technical field]
The utility model relates to water-cooled unit field, thermal power plant, particularly relates to a kind of condenser water charging system and efficiently sprays atomising device.
[background technology]
Steam turbine major part in the water-cooled unit of thermal power plant is to adopt surface condenser at present.Owing to there is heat transfer resistance to exist, the liberated heat heat exchange of condensing of cooling medium and steam is insufficient, and always the temperature than condensate is low to pass through temperature behind the condenser, and heat-economy is poor.Because more greatly then the steam liberated heat that condenses is just many more for displacement, the heat that cooling medium need be taken away is many more, yet the temperature of cooling heat, heat transfer area, cooling medium is limited by production cost.
[utility model content]
Based on this, be necessary to provide the sufficient condenser water charging system of a kind of heat exchange efficiently to spray atomising device.
A kind of condenser water charging system efficiently sprays atomising device; Comprise shell and condenser throat, top tube connector, bottom tube connector, filling pipe and atomising mechanism in the enclosure is installed; Said filling pipe is communicated with the middle part of said condenser throat; Said atomising mechanism comprises first atomising mechanism, second atomising mechanism, the 3rd atomising mechanism and the 4th atomising mechanism; Said first atomising mechanism is communicated with through the upper end of said top tube connector with said condenser throat; Said the 4th atomising mechanism is communicated with through the lower end of said bottom tube connector with said condenser throat, and said second atomising mechanism and said the 3rd atomising mechanism are installed in said condenser throat and are communicated with said condenser throat.
In a preferred embodiment, said atomising mechanism comprises mist pipe and atomizer, and said atomizer is installed on the mist pipe, and the middle part of said mist pipe is communicated with the end of said top tube connector.
In a preferred embodiment, the atomizer of said first atomising mechanism and said second atomising mechanism is provided with downwards, and the atomizer of said the 3rd atomising mechanism and said the 4th atomising mechanism upwards is provided with.
In a preferred embodiment, the internal diameter of the internal diameter of said top tube connector, bottom tube connector and said mist pipe is identical.
In a preferred embodiment, the internal diameter of said top tube connector and said bottom tube connector is less than the internal diameter of said condenser throat.
Above-mentioned condenser water charging system efficiently sprays atomising device, has reduced the heat transfer deviation in the supplementing water endothermic process, has reduced the irreversible loss in the diabatic process, has improved the hot merit conversion efficiency, and effectiveness of regenerator obviously improves.

[specific embodiment]
In order to solve the low problem of heat exchange efficiency, proposed the sufficient condenser water charging system of a kind of heat exchange and efficiently sprayed atomising device.
A kind of condenser water charging system efficiently sprays atomising device; Comprise shell 110 and be installed in condenser throat 120, top tube connector 130, bottom tube connector 140, filling pipe 160 and the atomising mechanism 150 in the shell 110; Filling pipe 160 is communicated with the middle part of condenser throat 120; Atomising mechanism 150 comprises first atomising mechanism, second atomising mechanism, the 3rd atomising mechanism and the 4th atomising mechanism; First atomising mechanism is communicated with the upper end of condenser throat 120 through top tube connector 130; The 4th atomising mechanism is communicated with the lower end of condenser throat 120 through bottom tube connector 140, and second atomising mechanism and the 3rd atomising mechanism are installed in condenser throat 120 and are communicated with condenser throat 120.
In the present embodiment, atomising mechanism 150 comprises mist pipe 152 and atomizer 154, and atomizer 154 is installed on the mist pipe 152, and the middle part of mist pipe 152 is communicated with the end of top tube connector 130.
In the present embodiment, the atomizer 154 of first atomising mechanism and said second atomising mechanism is provided with downwards, and the atomizer 154 of the 3rd atomising mechanism and the 4th atomising mechanism upwards is provided with.
In the present embodiment, the internal diameter of top tube connector 130, bottom tube connector 140 is identical with the internal diameter of mist pipe 152.
In the present embodiment, the internal diameter of top tube connector 130 and bottom tube connector 140 is less than the internal diameter of condenser throat 120.
Above-mentioned condenser water charging system efficiently sprays atomising device, has reduced the heat transfer deviation in the supplementing water endothermic process, has reduced the irreversible loss in the diabatic process, has improved the hot merit conversion efficiency, and effectiveness of regenerator obviously improves.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
