Description of drawings

Fig. 1 is a schematic structural diagram of a flue gas treatment device in a preferred embodiment of the present invention.

Detailed ways

As shown in Figure 1, a marine spiral spray flue gas treatment device includes an upper casing outlet flange 1, a washing liquid inlet flange 2, an upper casing 3, an upper casing cylinder flange 4, a lower casing Cylinder flange 5, hand hole 6, lower casing 7, flue gas spiral pipe 8, guide shell 9, inner support 10, porous nozzle 11, washing liquid cylinder 12, washing liquid inlet pipe 13 and spiral spray Tube 14.

The upper housing 3 and the lower housing 7 are connected through the upper housing cylinder flange 4 and the lower housing cylinder flange 5, and the upper housing 3 and the lower housing 4 form the shell of the flue gas treatment device. The outlet flange 1 of the upper casing is located on the upper part of the upper casing, and is used for exhausting the flue gas after washing. The washing liquid inlet flange 2 is located at the upper part of the shell, and is connected with the washing liquid inlet pipe 13 for pouring the washing liquid, and the washing liquid inlet pipe 13 is connected with the washing liquid cylinder body 12 . The flue gas spiral pipe 8 is a passage for flue gas, and its spiral pipe is coiled on the outer layer of the diversion shell 9 . The flue gas spiral pipe 8 is connected with a multi-hole nozzle 11, which is a cylindrical nozzle with a plurality of through holes. The multi-hole nozzle 11 is connected to the washing liquid cylinder 12. The washing liquid contained in the washing liquid cylinder 12 contacts. The washing liquid cylinder 12 is fixed with the lower casing 7 through the inner support 10 . The end of the washing liquid inlet pipe 13 is connected with the spiral spray pipe 14, and the spiral spray pipe 14 is provided with a perforated structure, and the washing liquid is sprayed out through the perforated structure on the spiral spray pipe 14 to contact with the rising flue gas.

In order to increase the contact area and time between the flue gas and the washing liquid, the untreated flue gas enters the multi-hole nozzle 11 through the flue gas spiral pipe 8, and contacts the washing liquid contained in the washing liquid cylinder 12 through the through holes on the multi-hole nozzle 11. , the gas after the washing liquid is in contact with the washing liquid sprayed out of the spiral spray pipe 14 again for secondary washing, and emerges from the bottom of the whole device through the channel between the diversion shell 9 and the washing liquid cylinder 12, When the washed flue gas rises from the bottom of the guide shell 9, it passes through the spiral pipe section in the flue gas spiral pipe 8. Since the flue gas with relatively high heat passes through the flue gas spiral pipe 8 at this time, the spiral pipe 8 The temperature of the outer wall is very high, and the flue gas after secondary washing can be dried, so the moisture is dried, and the flue gas after washing and drying emerges from the outlet flange 1 of the upper shell.

In Figure 1, A is the untreated flue gas inlet, and the untreated flue gas enters the flue gas spiral pipe 8 from A, and flows in the direction of the arrow. Place B is the washing liquid inlet flange 2, from where the washing liquid enters the washing liquid inlet pipe 13.

The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and changes according to the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art shall be within the scope of protection defined by the claims.
