Acid mist purification tower used for waste gas treatment and convenient for energy conservation

Abstract

The invention relates to an acid mist purification tower used for waste gas treatment and convenient for energy conservation. The tower comprises a tower body, a liquid supply mechanism, an exhaust pipe, a gas inlet pipe and a purification mechanism, the purification mechanism comprises a packing layer, a sealing ring and a dehydration assembly, the dehydration assembly comprises a screw rod, a threaded pipe and a driving unit, the liquid supply mechanism comprises a water tank, a material tank, a water pump and a spraying pipe, a partition plate and a baffle are arranged in the water tank, and a liquid supply assembly is arranged on the side, away from the baffle, of the partition plate. According to the acid mist purification tower used for waste gas treatment and convenient for energy conservation, alkali liquor can be discontinuously supplied to the packing layer through the liquid supply mechanism, an aqueous solution falling from the packing layer can be recycled and mixed with an alkali material in the material tank to prepare an alkali liquor, and in the purification mechanism, water in the packing layer is conveniently thrown out through the dehydration assembly, so that the alkalinity of the solution in the packing layer is ensured, the contact reaction with a large amount of acid mist is facilitated, the flowing frequency of the alkali liquor is reduced, the equipment energy consumption is reduced, and energy conservation is realized.

Description

technical field [0001] The invention relates to the field of acid mist purification, in particular to a convenient and energy-saving acid mist purification tower for waste gas treatment. Background technique [0002] Acid mist purification tower, also known as acid gas purification tower, acid mist purification tower, acid mist absorption tower, waste gas purification tower and glass cylinder acid mist purification tower, plays the role of removing harmful gases in waste gas, and has a wide range of applications and purification Low efficiency, low equipment resistance and small footprint. [0003] When the existing acid mist purification tower processes acid waste gas, in order to ensure that there is always lye in the packing layer inside the tower body that can neutralize the acidic substances in the waste gas, it is necessary to continuously spray lye to the packing layer, resulting in continuous energy consumption of the equipment. increase, and after the alkaline subs...

Problems solved by technology

[0003] When the existing acid mist purification tower processes acid waste gas, in order to ensure that there is always lye in the packing layer inside the tower body that can neutralize the acidic substances in the waste gas, it is necessary to continuously spray lye to the packing layer, resulting in continuous energy consumption of the equipment. increase, and after the alkaline substance in the filler layer reacts with the acid waste gas, and then sprays the lye on the filler layer, the lye that was sprayed will contact the water in the filler layer, and the alkalinity in the filler layer will decrease, which will not It is beneficial to neutralize and purify a large amount of acid waste gas, which reduces the practicability of the existing acid mist purification tower
