Abstract
A U-shaped finned tube bundle for million nuclear power steam-water separation reheater relates to a U-shaped finned tube bundle, which aims to the problems of low heat transfer performance and vulnerability of the existing U-shaped tube bundle. The tube bundle comprises a group of U-shaped heat exchange tubes with fins and a group of supporting plates; the group of U-shaped heat exchange tubes with fins are coaxially arranged to form the tube bundle which orderly penetrates through the group of supporting plates; and each supporting plate is fixedly connected with the tube bundle. The U-shaped finned tube bundle is suitable for heat transfer of the steam-water separation reheater.
Description
Technical field
The utility model relates to a kind of U-shaped finned-tube bundle.
Background technology
Existing nuclear power station saturated steam turbine group all will dispose separator (MSR) equipment.MSR receives the steam discharge from steam turbine high-pressure cylinder, removes the moisture in the moist steam and carries out heat again, drains into turbine low pressure cylinder then.Can significantly improve the power of unit through the steam of heat again, increase the economy of unit.Heating steam heat transferred pipe in the U-shaped tube bank of MSR will be managed is heated steam outward, and the heat transfer property of U-shaped tube bank plays crucial effects to the performance of MSR.
Present U-shaped tube bank heat transfer property is lower and fragile.
The utility model content
The purpose of the utility model provides a kind of U-shaped finned-tube bundle that is used for 1,000,000 nuclear power separators, to solve the present lower and flimsy problem of U-shaped tube bank heat transfer property.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: said tube bank comprises one group of U-shaped heat exchanger tube and one group of gripper shoe of having fin; One group of coaxial setting of U-shaped heat exchanger tube that has fin constitutes tube bank; One group of gripper shoe is passed in tube bank successively, and each gripper shoe is affixed with tube bank.
The utlity model has following beneficial effect: 1, the utlity model has heat transfer property height, not cracky or damage, simple in structure, the advantage of being convenient to processing and manufacturing; 2, increase the heat exchange area of pipe side in the utility model, strengthened the heat exchange of pipe side, made the exchange capability of heat of pipe both sides obtain reinforcement simultaneously, made the unit heat exchange area of U-shaped finned-tube bundle be far longer than the reheating pipe beam system of general type like this.
Description of drawings
Fig. 1 is the overall structure front view of the utility model.
The specific embodiment
The specific embodiment one: combine Fig. 1 that this embodiment is described; The tube bank of this embodiment comprises one group of U-shaped heat exchanger tube 1 and one group of gripper shoe 2 of having fin; One group of U-shaped heat exchanger tube 1 coaxial setting that has fin constitutes tube bank; One group of gripper shoe 2 is passed in tube bank successively, and each gripper shoe 2 is affixed with tube bank.
The specific embodiment two: combine Fig. 1 that this embodiment is described, the distance between per two gripper shoes 2 of this embodiment is 600-800mm.Other composition and annexation are identical with the specific embodiment one.
Operation principle: the utility model is arranged in separator (MSR) housing, and separator (MSR) both sides tube sheet is passed at the tube bank two ends, and horizontal arrangement is tightly connected each other.
When the utility model is restrained as low pressure; U-shaped heat exchanger tube 1 reheated steam that has fin is drawn gas from high pressure cylinder; Heating steam gets into the U-shaped heat exchanger tube 1 that has fin by taking over import; Through the mode heating high-pressure cylinder steam discharge of heat convection, the U-shaped heat exchanger tube 1 interior condensate that has fin enters into draining system;
When the utility model is restrained as high pressure; U-shaped heat exchanger tube 1 reheated steam that has fin is from initial steam; Heating steam gets into the U-shaped heat exchanger tube 1 that has fin by taking over import; Through the hot again high pressure cylinder steam discharge of one-level, U-shaped heat exchanger tube 1 condensate that has fin gets into water system through the heat convection heating.Through the steam entering low pressure (LP) cylinder steam turbine acting of heat again, to improve the utilization ratio of steam.
Claims (2)
1. U-shaped finned-tube bundle that is used for 1,000,000 nuclear power separators; Said tube bank comprises one group of U-shaped heat exchanger tube (1) and one group of gripper shoe (2) of having fin; It is characterized in that one group of coaxial setting of U-shaped heat exchanger tube (1) that has fin constitutes tube bank; One group of gripper shoe (2) is passed in tube bank successively, and each gripper shoe (2) is affixed with tube bank.
2. according to claim 1 or the 2 said U-shaped finned-tube bundles that are used for 1,000,000 nuclear power separators, it is characterized in that the distance between per two gripper shoes (2) is 600-800mm.
