[0002] Exhaust gas contains a large amount of harmful substances. If it is discharged directly without treatment, it will pollute the environment and affect human health. Therefore, it is necessary to use a purification tower to purify the exhaust gas before it is discharged. The existing purification tower consists of a tower body, a random packing layer and a spray layer arranged in the tower body from bottom to top, and an air inlet and an air outlet arranged at the bottom and top of the tower body respectively. Obviously, it has the following defects: First, because the air outlet is located at the top of the tower and the tower body is relatively high, scaffolding or cranes are required during construction, which makes the construction difficult and the safety risk high; second, because the random packing layer is loose and it is difficult to ensure the flatness, and the exhaust gas enters from the air inlet, the drainage is turbulent, so the exhaust gas on the packing is unevenly in contact with the agent sprayed from the spray layer, resulting in low purification efficiency and poor purification effect.

The outlet end of the liquid inlet pipe 6 is connected to the liquid spraying layer 2, and a plurality of the diffuser pipes 7 are evenly distributed between the two breathable baffles 3, and a plurality of air outlet holes with a smaller aperture than the particle size of the filler 8 are evenly opened on the peripheral wall of each of the two breathable baffles 3. The outlet end of each of the diffuser pipes 7 is located above the breathable baffle 3 and is blocked with a blind plate 9, and the inlet end is respectively connected to an outlet of the air inlet pipe 4. The inlet end of the air inlet pipe 4, the inlet end of the liquid inlet pipe 6 and the outlet end of the air outlet pipe 5 are all penetrated at the lower part of the outer wall of the tower body 1. The lower part of the outer wall of the tower body 1 is also provided with a liquid discharge port 10 located below the air inlet pipe 4, the liquid inlet pipe 6 and the air outlet pipe 5. Such a configuration, on the one hand, eliminates the need for scaffolding or cranes during construction, and construction workers can connect to the air intake, liquid intake, air outlet and liquid outlet on the ground; on the other hand, the filler 8 is constrained between the two breathable partitions 3, ensuring the neatness and compactness of the filler 8, and the cooperation of the air intake pipe 4 and the diffuser pipe 7 also avoids drainage turbulence, so that the air flow can be evenly diffused on the filler 8, and then evenly contact and react with the agent sprayed from the spray layer 2, achieving the technical effect of convenient and safe construction, high purification efficiency and good purification effect.

During use, the other end of the drain pipe 11 will always be immersed in the waste liquid after the reaction, so that while avoiding the occurrence of blockage, it prevents the untreated waste gas in the air inlet pipe 4 from mixing into the purified gas in the air outlet pipe 5.

[0019] At least one pair of symmetrical hanging noses 12 are provided on the outer side walls on both sides of the tower body 1. This arrangement makes it easy to move and rotate the purification tower.
