DETAILED DESCRIPTION OF THE EMBODIMENTS

[17] With reference to FIG. 1, a waste gas treatment tower by condensing and spraying comprises a tower body 1, a gas inlet 2 arranged at a bottom of the tower body, and a gas outlet 3 arranged at a top surface of the tower body. A first packing layer 4, a first spraying layer 5, a second packing layer 6, a second spraying layer 7 and a defogging layer 8 are successively provided in the tower from bottom to top. A protruding end of the gas inlet protruding into the tower body is bent downward to form a bent portion 18. The gas enters from the gas inlet and then successively passes through the first packing layer, the second packing layer and the defogging layer to be filtered and then is discharged from the gas outlet. The spraying is performed by providing the first and second spraying layers so that the gas is mixed with the liquid, and the particles mixed in the gas are entrained by the liquid. Through the arrangement of the first and second packing layers corresponding to the first and second spraying layers respectively, the gas and liquid can be mixed more uniformly. The spraying liquid returns to the bottom for self-separation. The separated organic solvent is collected and recovered via an automatic oil-water separator. By providing the bent portion, the movement direction of the waste gas entering from the gas inlet pipe is changed, so that the waste gas moves downward and is mixed with the water at the bottom of the tower, and a part of the large particulate matter is filtered in advance.

[18] The first and second packing layers are both Pall ring packing layers. Pall rings provide a uniform distribution of the liquid due to cutouts on the ring wall, resulting in more uniform mixing of the liquid with the gas.

[19] The first and second spraying layers each comprise a first water inlet pipe 9, and at least three shunt pipe groups are uniformly distributed on the first water inlet pipe. The shunt pipe group comprises two shunt pipes oppositely arranged with the first water 2 inlet pipe as a central axis. Exposed ends of the shunt pipes are all provided with LU501499 nozzles 11. The shunt pipe is in communication with the first water inlet pipe. By providing at least three groups of shunt pipes and nozzles on exposed ends of the shunt pipes, the distribution of nozzles is more uniform, the spraying effect is good and the range is wide.

[20] A first shunt pipe group 12, a second shunt pipe group 13 and a third shunt pipe group 14 are successively provided on the first water inlet pipe from left to right. The length of the shunt pipe of the second shunt pipe group is greater than the length of the shunt pipe of the first shunt pipe group, and the length of the shunt pipe of the first shunt pipe group is equal to the length of the shunt pipe of the third shunt pipe group. Since the middle shunt pipe has the longest length, the distribution of nozzles has a hexagonal structure, increasing the spray range.

[21] Each sides of the tower body are uniformly distributed with three view openings

15. It is convenient to view the conditions inside the tower by providing the view openings.

[22] The defogging layer is a baffle plate defogging layer. By setting the baffle plate defogging layer, the defogging effect is good.

[23] An outside of the tower body is provided with a water tank 10 in communication with the bottom of the tower body, and the water tank is provided with a second water inlet pipe 17 in communication with the first water inlet pipe; and one end of the second water inlet pipe inserted into the water tank is connected to a circulating water pump 16. The water tank is in communication with the tower body via a connecting pipe. The water in the water tank is cooled by a refrigerator, and the water temperature is cooled to 0°C-5°C. The circulating water flowing into the water tank from the tower body is driven into the first water inlet pipe via the second water inlet pipe by a circulating water pump, so as to supply water to the spraying layer, thereby achieving water recycling.

[24] The central angle a of the bent portion is 45°. Using 45°can obtain the best guiding effect.

[25] The above is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change to the above embodiment in essence according to the technology of the invention falls within the scope of the present invention.
