[0029] The condensing tower 2 comprises an upper tower body 8 and a lower tower body 9 connected to each other through flanges; the gas inlet and outlet area and the pipeline area are installed in the upper tower body 8, the condensing area is installed in the lower tower body 9, and the heat exchange chambers of the first heat exchange mechanism and the second heat exchange mechanism are connected; first, the split structure makes the installation, disassembly and maintenance of the vertical condensing tower body more convenient, and reduces the maintenance cost and time. When it is necessary to clean or replace the internal components, the flanges can be easily disassembled, and the entire tower body does not need to be disassembled.

[0030] The condensing tower 2 is provided with a partition plate 3 corresponding to the position of the gas inlet and outlet area, the partition plate divides the gas inlet and outlet area into a gas inlet area 4 and a gas outlet area 5, the gas inlet area is connected with the gas inlet, the gas outlet area is connected with the gas outlet, the high-temperature gas forms a U-shaped gas flow channel through the gas inlet area, the pipeline condensing area and the gas outlet area, the lower tower body is provided with a conical collecting cavity 14 corresponding to the bottom of the condensing area, the bottom of the conical collecting cavity 14 is provided with a liquid discharge valve 15, and the condensing tower is provided with a liquid level meter 16 for monitoring the liquid level in the conical collecting cavity; the condensed water can be conveniently discharged, and the accumulation of the condensed water and the possible damage to the system are avoided.

At the same time, the heat exchange cavities in the upper tower body and the lower tower body are connected through the U-shaped communication pipe, so that the cooling liquid can flow smoothly between the two heat exchange cavities, further enhancing the uniformity and stability of heat exchange.
