Problems solved by technology

[0004] The purpose of the present invention is to invent a new type of tube bundle on the basis of not reducing the heat transfer performance of the condenser itself, in order to solve the problem that the size of the water chamber and the tube sheet of the existing condenser is relatively large due to the reduction of the tube sheet layout ratio , there are problems of heavy equipment and high production cost

specific Embodiment approach 1

[0018] Specific implementation mode one: combine Figure 1 to Figure 5 This embodiment is described. This embodiment includes a condenser shell 1 and a tube sheet 2. The tube sheet 2 is eccentrically embedded in the condenser shell 1. It also includes an air extraction pipe 3, a main condensation area and an air cooling area D. The air extraction tube 3 is coaxially installed in the condenser cylinder 1, and the entire tube bundle is arranged on the tube plate 2 in the form of a "wing". The main condensation zone includes a plurality of heat exchange tubes 6 and two condensation baffles 4, and the plurality of heat exchange tubes 6 are arranged in a "wing-shaped" tube bundle in the form of a 60° fork row, and the "wing-shaped" tube bundle is provided with A plurality of condensing steam inlet channels 7 and a plurality of heat exchange tubes 6 form the upper left condensation zone A, the upper right condensation zone B, the lower condensation zone C, and the air cooling zone D...

specific Embodiment approach 2

[0022] Specific implementation mode two: combination figure 1 To describe this embodiment, the outer contour shape of the plurality of heat exchange tubes 6 in the main condensation zone of this embodiment is adapted to the radian of the inner cylinder of the condenser cylinder 1 . Such setting conforms to the flow boundary shape of the steam, so that the steam can better enter the inside of the tube bundle. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0023] Specific implementation mode three: combination figure 1 To illustrate this embodiment, the outer edge of the tube bundle formed by the main condensation zone and the air cooling zone D of this embodiment forms a channel with a tapering ratio of 0.5-0.7 along the axis direction of the condenser cylinder 1 . Such setting satisfies the flow law of steam condensation. During the flow process, the steam condenses continuously, and the volume occupied by the steam gradually decreases. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a condenser, and particularly relates to a condenser with wing-shaped tube bundles arranged in a cylinder. According to the condenser with the wing-shaped tube bundles arranged in the cylinder, on the basis of high condensation performance and high heat transfer performance, the problems that a conventional condenser is large in water chamber size and tube plate size, heavy in equipment and high in production cost due to the fact that the tube distribution rate of tube plates is low are solved. The condenser comprises a condenser cylinder and a tube plate, the tube plate is eccentrically embedded in the condenser cylinder, the condenser further comprises an evacuation air tube, a tube bundle main condensing area and an air cooling area, the evacuation air tube is coaxially mounted in the condenser cylinder, the whole tube bundle is arranged on the tube plate in a wing shape, and the air cooling area is arranged at the lower middle portion of the tube bundle and located under the evacuation air tube. The tube bundle of the condenser is arranged in a wing shape, the tube distribution rate of the tube plate is substantially improved, the diameter of the water chamber cylinder and the diameter of the tube plate are reduced, the application amount of steel is reduced, and the overall weight and related cost of the equipment are reduced. The condenser with the wing-shaped tube bundles arranged in the cylinder is applied to the condensers.

Description

technical field [0001] The invention relates to a condenser, in particular to a condenser arranged as a wing-shaped tube bundle in a cylinder. Background technique [0002] With the development and application of various modern energy-saving technologies, technological updates are increasing day by day. For small and medium-sized condensers or heat network condensers, the original double-channel condensers have been replaced by some single-channel condensers. The tube bundle type of the double-channel condenser can be used on the single-channel condenser, but since the double-channel condenser is two independent tube bundles, there is a relatively large steam inlet channel in the middle, so that the tube sheet layout ratio The size of the water chamber is relatively large, the equipment is heavy, steel is consumed, and transportation and other related costs are increased. [0003] To sum up, on the basis of not reducing the heat transfer performance of the condenser itself,...
