[0002] In recent years, for the shell-and-tube modified graphite condensers used in the chlorination reactors in industrial chloroacetic acid production, due to large temperature differences during use, the top of the heat exchange tubes often becomes loose and leaks between the tube sheets. Generally, the thermal expansion method is used for repair. After repair, the service life is short, and the surrounding heat exchange tubes are affected during the repair process. To solve the problems of low leak plugging efficiency, high cost, complex operation, and high repair rate, a rapid leak plugging device for a modified graphite condenser of a chlorination kettle is needed.

[0003] In the prior art, such as: CN215522456U, a rapid leak plugging device, the rapid leak plugging device includes a first half-tube housing, a second half-tube housing, a connecting part, a first straight sealing strip, a second sealing strip, two first arc-shaped sealing strips, and two second arc-shaped sealing strips. When the rapid leak plugging device is in the first state, the first flat substrate is connected to the second flat substrate through the connecting part, and the first arc-shaped sealing strip and the second sealing strip on the same side are hermetically pressed against each other to form an annular seal, and the first straight sealing strip and the second sealing strip are hermetically pressed against each other to form a linear seal; when the rapid leak plugging device is in the first state, the first half-tube housing and the second half-tube housing are open along their hinge axes.

Through the sliding and fixing method, the installation and fixation of the device are more convenient, and the use of the leak plugging device is faster.

[0027] The outer surface wall of the bottom fixed ring 2 is fixedly connected with a liquid outlet screw pipe 13. The outer surface wall of the liquid outlet screw pipe 13 is threadedly connected with a bottom connection cover 10. The top of the bottom connection cover 10 is fixedly connected with a piston 12.
