U-shaped tube heat exchanger with baffle plate with air bag structure

Abstract

The invention discloses a U-shaped tube heat exchanger with a baffle plate provided with an air bag structure. The U-shaped tube heat exchanger comprises a cylinder body, a shell flange gasket a, a shell flange gasket b, a shell flange a, a shell flange b, a tube plate component, an elliptical head a, an elliptical head b, a tube box cylinder body, a pass partition plate, a welding neck flange a,a welding neck flange b, a welding neck flange c, a welding neck flange d, a saddle support a, a saddle support b, an equal-length stud and a hexagon nut; the tube plate component is composed of a tube plate, a baffle plate a, a baffle plate b, a baffle plate c, a baffle plate d, a connecting plug a, a connecting plug b, a connecting plug c, a connecting plug d, a connecting plug e, a connecting plug f, an air conduit a, an air conduit b, an air conduit c, an air conduit d, a U-shaped heat exchange tube, a distance tube, a pull rod and an air bag. The vibration at the gap of the baffle plate and the cylinder boxy and fluid short-circuit due to the own structure of the U-shaped tube heat exchanger can be effectively solved by adopting the air bag structure.

Description

technical field [0001] The invention relates to the field of U-shaped tube heat exchangers, in particular to a U-shaped tube heat exchanger with a baffle plate and an air bag structure. Background technique [0002] In today's world, due to the rapid development of economy and industry, countries all over the world are generally facing the problem of energy shortage. The development of new energy and how to efficiently use existing energy have attracted widespread attention from all countries in the world. There are various types of heat exchangers, but shell-and-tube heat exchange equipment occupies a dominant position in chemical and petrochemical production, especially in operations where the medium is corrosive or high-temperature. Shell-and-tube heat exchangers have the advantages of high safety and reliability, and can be suitable for various occasions, and are most widely used in various industrial fields. For more than half a century, with the rapid development of m...

Problems solved by technology

However, due to the structure of the U-shaped tube heat exchanger itself, the baffles are not fixed with the cylinder, but are connected with U-shaped heat exchange tubes, tube sheets, tie rod distance tubes and spacer tubes. As a whole, it can be pulled out from the cylinder as a whole when cleaning, so there must be a gap between the baffle and the cylinder. During the operation of the U-shaped tube heat exchanger, it is easy to cause a gap between the baffle and the cylinder. The vibration between the baffles and the gap between the cylinder will cause the short circuit of the fluid, which will affect the heat exchange efficiency and reduce the service life of the U-tube heat exchanger.
