The invention aims to provide an environment-friendly device for strongly oxidizing impurities such as sulfur dioxide and the like, and then desulfurizing, denitrifying and purifying micro-dust by using a liquid bath and spraying method. It is composed of ozone generator, strong oxidation chamber, flue, air inlet, tower body, gas cyclone distributing plate, horizontal fine screen plate, microporous filter material, rotary nozzle, rotary union, force couple nozzle, air outlet, demisting plate, manhole door, pipeline, liquid pump, foot margin and blow-off valve. The method is characterized in that: the bottom of the tower body is provided with a gas inlet, the upper part of the gas inlet is provided with a plurality of horizontal fine mesh plates, the bottom of the tower body is provided with a blowoff valve, the lower part of the tower body is provided with liquid, the right side of the valve body is provided with a liquid pump, the inlet of the liquid pump is connected with the liquid arranged at the lower part of the tower body, the outlet of the liquid pump is connected with the rotary spray head through a pipeline, the gas inlet is communicated with a strong oxidation chamber, the strong oxidation chamber is connected with a flue, and an ozone generator is communicated with the strong oxidation chamber.
When the strong oxidation liquid bath spraying purification tower is used, the gas outlet of the strong oxidation liquid bath spraying purification tower is connected with the induced draft fan, the gas inlet of the strong oxidation liquid bath spraying purification tower is connected with the strong oxidation chamber, and the strong oxidation chamber is connected with the outlet flue of the pre-stage dust remover. The liquid level of the liquid in the tower body is higher than the horizontal fine mesh plate. When the induced draft fan works, when gas passes through the strong oxidation chamber, impurities in the gas are oxidized into oxides, when the gas passes through liquid, the soluble oxides are dissolved by the liquid, and the insoluble oxides are captured by the liquid. If sulfur dioxide in the gas and ozone generate chemical reaction to generate sulfur trioxide, the sulfur trioxide and liquid generate chemical reaction when the sulfur trioxide flows through the liquid in the tower body, so that the sulfur in the gas is removed. The liquid can be water, sulfuric acid, or alkaline solution such as magnesium hydroxide and calcium hydroxide.
The horizontal fine screen plate divides the gas into a plurality of micro gas flows to increase the contact area of the gas and the liquid, so that the reaction is more sufficient, the horizontal fine screen plate enables the gas to form a plurality of micro bubbles, the bubbles can be extinguished and regenerated when passing through one horizontal fine screen plate, and impurities in the bubbles are soaked in the liquid. Adopt the route of gas whirl distributing plate aim at increase air current, adopt rotatory nozzle's aim at to form multilayer annular scanning liquid stream, scanning liquid stream and air current fully contact to improve gaseous purification efficiency, the purpose of adopting the micropore filter material is that the micropore filter material can adsorb a large amount of liquid, keeps the moist state, and when gas passed through the micropore filter material, impurity such as sulfur trioxide was absorbed by the liquid in the micropore filter material, in order to improve gaseous purification efficiency.
The strong oxidation liquid bath spray purification tower can efficiently carry out desulfurization and denitrification and remove micro dust. The product of the desulfurization is sulfuric acid or sulfate. When the liquid adopts water or sulfuric acid, the sulfur trioxide is absorbed, the concentration of the sulfuric acid is concentrated, the sulfuric acid can be repeatedly used after the water is added for slight dilution, and the desulfurization can be operated without consumables.
The product of the traditional desulfurizing tower is partially nitrite, the chemical stability is poor, and consumables such as magnesium oxide, calcium oxide and the like are continuously added.

Detailed Description
Example 1 strong oxidation microporous filter material liquid bath spray purification tower
A strong oxidation micropore filter material liquid bath spray purification tower is shown in figure 1, a tower body 5 is arranged on a foundation 16, a manhole door 12 is arranged on the side surface of the tower body, a plurality of gas rotational flow distribution plates 6 are arranged in the tower body, micropore filter materials 19 are arranged on the gas rotational flow distribution plates below, a rotary movable joint 8, a couple nozzle 9 and a rotary nozzle 7 are arranged below each gas rotational flow distribution plate, the rotary movable joint, the couple nozzle and the rotary nozzle form a rotary spray head, an air inlet 4 is arranged at the left lower part of the tower body, a plurality of horizontal fine mesh plates 18 are arranged above the air inlet, a blow-down valve 17 is arranged at the bottom of the tower body, liquid 14 is arranged at the lower part of the tower body, a liquid pump 15 is arranged at the right side of the tower body, the inlet of the liquid pump is communicated with the liquid at the lower part of the tower body, the outlet of the liquid pump is connected with, the ozone generator 1 is communicated with the strong oxidation chamber.
In this embodiment, water or sulfuric acid is used as the liquid. The liquid level of the liquid in the tower body is higher than the horizontal fine mesh plate.
When the induced draft fan works, gas passes through the strong oxidation chamber, ozone is contained in the strong oxidation chamber, impurities in the gas in the strong oxidation chamber are oxidized into oxides, and then the impurities and the oxides are captured by adopting a liquid bath and spraying method. Whether the oxide is soluble or insoluble, is captured by the liquid. For example, sulfur dioxide is oxidized to sulfur trioxide in a strong oxidation chamber, and the sulfur trioxide is absorbed by the sulfuric acid as it flows through the sulfuric acid in the tower. In this case, facilities such as a horizontal fine mesh plate, a microporous filter material, an airflow swirling plate, a rotary shower head, and the like are used to improve the adsorption efficiency.
Example 2 strong oxidizing liquid bath spray empty column
In this case the horizontal fine mesh sheet and the microporous filter material are omitted. The level of the liquid is lower than the gas inlet 4 so that the resistance of the system can be greatly reduced.
In this case, desulfurization and denitrification and bath dust removal were carried out completely by liquid spraying.
