Problems solved by technology
However, part of the fluid in the U-shaped tube heat exchanger directly passes through the gap between the baffle plate and the inner wall of the cylinder, causing a short circuit and reducing the thermal efficiency of the heat exchanger. This is a long-standing technical problem of the U-shaped tube heat exchanger.

A U-shaped tube heat exchanger baffle assembly, the baffle assembly includes first baffles and second baffles alternately arranged up and down on the heat exchange tubes, and the first baffle and the second baffle The tie rods on the inner side of the edge of the two baffles, and the support tubes respectively arranged between every two baffles and between the baffles and the tube sheet and covering the surface of the tie rods; the second baffles are located in the U-shaped heat exchange tube The upper and lower sides of one end of the bend area, and one end of the tie rod is fixed in the tube plate, and the other end is respectively fixedly connected with the end of the second baffle through nuts. The present invention also provides a fixing and sealing method for the baffle assembly, including the steps of fixing the baffle, installing the heat exchange tube, penetrating into the cylinder, and locking the nut. The present invention can realize the folding of the U-shaped tube heat exchanger. The flow plate is fixed on the cylinder and sealed, so that the U-shaped tube heat exchanger has the advantages of the fixed tube plate heat exchanger while maintaining its own advantages.
Description
technical field [0001] The invention relates to the technical field of heat exchanger equipment, in particular to a U-shaped tube heat exchanger baffle assembly and a fixing and sealing method thereof. Background technique [0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid. It occupies an important position in many industrial productions such as chemical industry, petroleum, power, food and nuclear power, and is widely used. Among them, the fixed tube sheet heat exchanger and the U-shaped tube heat exchanger are used more frequently. The fixed tube sheet heat exchanger is welded and fixed on two tube sheets and multiple baffles on the cylinder, and a large amount of heat is exchanged. The tubes are penetrated in sequence, and the advantage of the fixed tube sheet heat exchanger is that the baffle and the cylinder are fixedly connected, the vibration resistance is good, and the seal between the baffle and the cylinder is realized, w...
