[0029] One end of the spray main pipe 2 is connected to a device for providing scrubbing liquid in the scrubbing tower.

[0030] The nozzles 4 are uniformly distributed in the horizontal cross section of the scrubbing tower. When the number and position of the nozzles are arranged, the atomizing effect should be able to fully cover the cross section of the scrubbing tower, and too much scrubbing liquid should not be hung on the inner wall of the tower.

[0031] The scrubbing liquid flows through the spray pipe, is atomized and sprayed out through the nozzles 4, and is uniformly distributed in the scrubbing tower.

[0032] The nozzles are arranged at intervals on the spray pipe according to the fluid simulation mode.

[0033] The flow rates of the nozzles are consistent, and the spray atomizing effect is consistent.

[0034] When the scrubbing tower is in operation, the flue gas contacts the scrubbing liquid, the substances in the flue gas contact the scrubbing liquid, the harmful components in the flue gas are absorbed, and the flue gas treatment is realized.

[0035] In actual application, the scrubbing liquid can be a circulating scrubbing liquid, which can reduce the consumption.

[0036] When the scrubbing tower is in operation, the nozzles spray the atomized circulating scrubbing liquid, the nozzles are arranged at intervals, the flow rates of the nozzles are consistent, the spray atomizing effect is also consistent, and the circulating scrubbing liquid can be uniformly distributed in the scrubbing tower. The circulating scrubbing liquid and the substances in the flue gas fully contact and react, the harmful substances in the flue gas are removed, and the flue gas meets the standard.

[0037] The beneficial effects of the present embodiment are that the spray pipe of the nozzle device is arranged in a symmetrical branch shape, and the various atomizing nozzles are distributed at intervals, which can effectively improve the spraying effect. The nozzle device can make the spraying and atomizing effects of each atomizing nozzle equivalent, evenly distribute the circulating washing liquid, improve the atomizing gas-water contact efficiency, make the flue gas fully contact with the circulating liquid, and improve the treatment effect of the washing tower on organic waste gas. Even in the case of damage to individual atomizing nozzles, the atomizing and spraying effects of each atomizing nozzle do not change.

Figure 1 , 2 and 3, a new type of washing tower nozzle device is installed and fixed in a washing tower 1, the nozzle device includes a spray pipe, the spray pipe includes a transversely centrally arranged spray main pipe 2 and a plurality of spray branch pipes 3 arranged symmetrically perpendicular to the spray main pipe 2; the spray branch pipe 3 includes a connecting end 31 and a free end 32, the connecting end 31 is in communication with the spray main pipe 2; a plurality of nozzles 4 are arranged on the spray main pipe 2 and the spray branch pipe 3 respectively, the distance between adjacent nozzles 4 on the spray main pipe 2 is the same, the nozzles 4 on the adjacent two spray branch pipes 3 are arranged staggered, and the distance between adjacent nozzles 4 on the same spray branch pipe 3 is the same; the distance between the free end 32 of each spray branch pipe 3 and the inner wall of the washing tower is less than the distance between adjacent nozzles 4, and the distance between the nozzle 4 close to the inner wall of the washing tower and the inner wall of the washing tower is less than the distance between adjacent nozzles 4; the nozzle 4 includes a sleeve flange and an atomizing nozzle 41, the atomizing nozzle 41 is in communication with the spray main pipe 2 or the spray branch pipe 3 through the sleeve flange.

[0047] Preferably, the atomizing element is a porous ceramic sheet or a cyclone sheet.

[0054] When the scrubbing tower is running, the washing liquid is atomized by the nozzles and sprayed out from top to bottom, contacts with the flue gas flowing upward in the scrubbing tower, absorbs the harmful components in the flue gas, and realizes flue gas treatment.

[0055] In actual application, the washing liquid can be a circulating washing liquid, reducing consumption.

[0056] When the scrubbing tower is running, the circulating washing liquid is atomized and sprayed out by each nozzle. Due to the interval distribution of the nozzles, the nozzle flow rate of each atomizing nozzle is consistent, and the spray atomization effect is also comparable, which can make the circulating washing liquid uniformly distributed in the scrubbing tower. The circulating washing liquid and the substances in the flue gas fully react, removing the harmful substances in the flue gas and making the flue gas meet the standard.

[0057] The beneficial effects of the present embodiment are that the spray pipe of the nozzle device uses a corrosion-resistant structure, which can increase the service life; the atomizing nozzle uses a simple structure without affecting the atomization effect; the nozzle can be replaced very conveniently, even when the scrubbing tower is running, the nozzle can be removed or replaced by removing the sleeve flange, which is convenient for operation and maintenance.
