Embodiment

[0017] Such as figure 1 As shown, the acid / alkali waste gas purification treatment system described in this embodiment includes a reaction tower 1, a dosing tank 4 and a circulation device. The top of the reaction tower 1 is provided with an air inlet 2, and the bottom of the reaction tower 1 is provided with an outlet. The gas port 3 and the dosing tank 4 communicate with the bottom of the reaction tower 1. The dosing tank 4 is provided with a drug inlet 5 and a liquid outlet 6. The circulation device includes a circulation pump 7 and a liquid return pipe. The dosing tank 4 passes through the liquid return The pipe is communicated with the liquid inlet of the circulation pump 7, and the upper part of the reaction tower 1 is communicated with the liquid outlet of the circulation pump 7 through the liquid return pipe.

[0018] In order to observe the reaction of the solid packing in the reaction tower 1 conveniently, preferably, the reaction tower 1 of this embodiment is provid...

Abstract

The invention discloses an acid-alkali waste gas purification treatment system. The acid-alkali waste gas purification treatment system comprises a reaction tower, a chemical adding tank and a circulating device, wherein the top of the reaction tower is provided with a gas inlet, the lower part of the reaction tower is provided with a gas outlet, the chemical adding tank is communicated with the bottom of the reaction tower, a chemical inlet and a liquid drainage hole are formed in the chemical adding tank, the circulating device comprises a circulating pump and a liquid return pipe, the chemical adding tank is communicated with a liquid inlet of the circulating pump by the liquid return pipe, and the upper part of the reaction tower is communicated with a liquid outlet of the circulating pump by the liquid return pipe. With the adoption of the structure, the acid-alkali waste gas purification treatment system can thoroughly purify acid-alkali waste gas and can achieve high purification efficiency.

Description

technical field [0001] The invention relates to the field of waste liquid metal recovery, in particular to an acid / alkali waste gas purification treatment system. Background technique [0002] Waste gas purification mainly refers to the work of treating industrial waste gas generated in industrial places, such as dust particles, flue gas smoke, odorous gas, and toxic and harmful gases. Common waste gas purification includes factory smoke and dust waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc. At present, the general acid-base exhaust gas purification adopts the multi-media catalytic oxidation process. The principle is to first fill the reaction tower with a special solid packing, and the packing is compounded with a multi-media catalyst. When the acid-base gas passes through the packing under the action of the induced draft fan ...
