The load and the temperature of solar power plant frequently have greatly changed, and depend primarily on time, date and weather conditions, prove that with this steam generator that is designed for solar energy thermal-power-generating factory is difficult.The quick toggle speed of high-temperature gradient, low spatial demand and low production and operating cost only is the part to the heat exchanger important need of the generation steam that is used for solar power plant.
Therefore, still need a kind of compacter, more effective heat exchanger that is used for solar power plant, in addition, can also produce and security of operation with lower cost.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of heat exchanger that allows compact arrangement, economical and effective production, safe operation.
This purpose realizes through the heat exchanger according to independent claims.Provide preferably in the dependent claims and further developed.
The heat exchanger that is used for the generation steam of solar power plant according to the present invention comprises: the outer shell with inlet nozzle and outlet nozzle that is used for heat eliminating medium.Heat exchanger further comprises inlet header and the outlet header that is used for heat-absorbing medium (preferred water), and inlet header and outlet header are arranged in the outer shell basically.In addition; In outer shell, further be provided with tube bank; Tube bank comprises a plurality of pipe layers with continuous pipe, manages continuously so that the mode that heat eliminating medium can flow around pipeline fully be provided with, and is designed to supply heat-absorbing medium to flow to the flow path of outlet header from inlet header.Tube bank is provided with circuitous mode.The heat exchanger that produces steam according to the present invention designs according to the forced flow principle, makes the heat-absorbing medium that is supplied to inlet header in flow path, successively carry out preheating, evaporation and superheated, and superheated steam is discharged from outlet header.Preheating, evaporation and superheated institute energy requirement are all taken from the heat transmission from the heat eliminating medium to the heat-absorbing medium in the outer shell basically.
Therefore, heat exchanger is incorporated into and contains three kinds of different devices less, and these three kinds of devices are preheater, evaporimeter, superheater.Because the circuitous setting of pipeline is according to adverse current or cross-flow principle generation heat exchange.Heat-absorbing medium, preferred water flows through circuitous pipeline.Because the circuitous setting of tube bank, integral body has reduced the total size of heat exchanger, has improved the heat transmission from heat eliminating medium to heat-absorbing medium, and then has improved the thermoelasticity of configuration.
Because being used for the heat exchanger of the generation steam of solar power plant is configured according to the forced flow principle; That is, the heat-absorbing medium of supply, preferred water; In " passage " of inlet header to outlet header, carry out preheating; Evaporate subsequently, carry out superheated at last, realized very compact and effective steam generator.Do not use the several independent heat exchange module of the interconnection of costliness and complicacy; Water gets into heat exchanger via inlet header under fluid state; Preheating, evaporation and superheated are carried out towards the direction of outlet header in the edge when in heat-exchange tube, flowing; Make superheated steam pass through outlet header and discharge heat exchanger, this superheated steam can offer the steam turbine of generating.
