Description

Rod and tube bundle propeller

Technical Field

The utility model relates to a baffling pipe heat exchanger technical field specifically is a baffling pole tube bank propeller.

Background

In order to effectively meet the increasing demands of national economy such as chemical fiber, light industry, electronics, buildings and the like, the PTA is used as a basic organic raw material of the products, and the increasing demand of the PTA determines that the PTA production equipment is inevitably developed to be large-scale and high-end. Therefore, in recent years, large rod baffle heat exchangers have been widely used in PTA projects by virtue of their excellent gas heat exchange effect.

The manufacturing process of the tube bundle and the shell of the rod baffle heat exchanger is basically mature at present, but for the ultra-long and ultra-heavy rod baffle heat exchangers, the manufacturing process of pushing and assembling the tube bundle and the shell still has certain difficulty due to the fact that the rigidity of the rod baffle tube bundle is poor and the rod baffle tube bundle is easy to bend.

In the prior art, a part of heat exchange tubes penetrate when the tube bundle is prefabricated, only a certain rigidity of the whole tube bundle frame is required to be ensured, the whole tube bundle frame is convenient to assemble with a shell, and the rest heat exchange tubes penetrate after the tube bundle frame is assembled with the shell. The type is suitable for the tube bundle of the ultra-heavy heat exchanger, has the advantages of reducing the propelled weight of the tube bundle, reducing the requirements on hoisting equipment of a manufacturing plant such as a crane and a lifting appliance, and being convenient for assembling with the shell. The defect is that under the condition that the length of the heat exchange tube is long, the actual condition that the heat exchange tube is pushed forwards cannot be seen in the process of passing the heat exchange tube, the probability that the heat exchange tube passes through a baffle rod hole/baffle plate hole is high, the heat exchange tube is finally possibly bent and deformed and scrapped, even the condition that the heat exchange tube cannot pass through the heat exchange tube is caused, the tube bundle is extracted, and the like, so that the labor is wasted, and the working progress is seriously influenced.

The other traditional mode is that two temporary lifting lugs are welded at the two horizontal sides of the tube plate, the two temporary lifting lugs are also welded on the two horizontal sides of the shell and the same horizontal line of the lifting lugs on the tube plate, then the temporary lifting lugs on the tube plate and the shell are respectively connected through an electric block or a chain block to pull the tube bundle into the shell, but the tube bundle is overlong and overweight, and the process for assembling the traditional tube bundle and the shell has potential safety hazards and needs more manpower and working hours.
