[0003] The utility model aims to provide a pressure vessel with a detachable baffle. In the original tubular heat exchanger, a plurality of tubes are arranged side by side inside to form a tube pass. The tubes are connected by flanges at two ends of an outer shell. The heat exchange medium circulates at a fast speed, the heat exchange efficiency is low, and it is inconvenient to disassemble the baffle, which is troublesome to replace.

[0004] In order to achieve the above-mentioned purpose, a pressure vessel with detachable baffles is provided, comprising: a heat exchanger body, a plurality of baffles are fixedly connected to the inner wall of the heat exchanger body, a first tie rod and a second tie rod are respectively provided in the middle of the plurality of baffles, one end of one of the second tie rods passes through the middle of two of the baffles, flanges are provided at both ends of the heat exchanger body, one end of one of the flanges is provided with a connecting end, and one ends of the plurality of second tie rods are respectively matched with the connecting ends.

[0005] According to the pressure vessel with detachable baffles, both flange side walls are provided with steel plates, and the steel plate side walls are provided with through holes.

[0006] According to the pressure vessel with detachable baffles, the plurality of baffles are arranged in a semicircular arc, and one end of the second pull rod is threadedly connected to the connecting end.

[0007] According to the pressure vessel with detachable baffles, the first tie rod and the second tie rod are both solid steel bars.

[0008] The above scheme has the beneficial effects: the utility model sets a number of baffles to make the medium flow in an S shape, which is used to block and change the direction and route of the medium flow, and can increase the flow speed of the heat exchange medium. The baffle is a semicircular plate, and the arc-shaped side is fixedly connected to the inside of the shell. A number of holes are provided for the tubes to pass through, and a number of holes are provided for the pull rods to pass through. The pull rods are solid steel bars, one end of which is fixedly connected to the baffle bolts, and the other end is threadedly connected to the shell end flange. The pull rods are used to install and fix the baffles, so that the baffles can be removed conveniently after the flanges are removed.

[0009] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
