Technical Field
The utility model relates to a heat exchanger field particularly, relates to a group of baffling rod heat exchanger is to frock.
Background
The shell-and-tube heat exchanger is widely applied to the industries of chemical industry, petroleum, energy, metallurgy and the like, and accounts for about 70 percent of the total amount of the heat exchanger. The traditional shell-and-tube heat exchanger adopts plate type baffle plates, the shell fluid transversely scours the tube bundle under the action of the baffle plates, the tube bundle can be induced to vibrate under a high-speed state, and the heat exchange tube is broken when the tube bundle is serious. Rod-type baffling heat exchangers are developed in order to solve the problem that the heat exchange tubes of the baffling heat exchanger are vibrated due to the transverse flushing of fluid. The main characteristic is that the shell side is not provided with baffle plates, and baffle rings composed of baffle rods replace the baffle plates, so that the pipe is supported, and the fluid is disturbed, thereby achieving the purpose of strengthening heat transfer. The shell side fluid velocity of the rod baffle heat exchanger is uniformly distributed in the whole shell side section, no serious flow dead zone exists, the flow resistance loss is reduced, and the generation of dirt deposition and corrosion is reduced.
The support structure of the baffle rod heat exchanger tube bundle is characterized in that baffle rods are used for fixing each heat exchange tube in four directions. The baffle rods are welded on the baffle rings, and the four baffle rings form a group and clamp the heat exchange tube from four directions. The tube bundle supporting structure composed of the baffle rings is like a large cage and has good shock resistance. The manufacturing core of the rod baffle heat exchanger is a baffle ring cage consisting of baffle rings, so the manufacturing precision of the baffle rings becomes an important control point for manufacturing the rod baffle heat exchanger. In order to realize the accurate positioning of the deflection rod on the deflection ring, a group of clamping tools are required to be manufactured for the assembly and welding of the deflection rod and the deflection ring, and the clamping tools have the defects of time consumption in manufacturing, high manufacturing cost and incapability of repeated reuse.
An effective solution to the problems in the related art has not been proposed yet.
