Modularized dynamic gas purification tower

Abstract

The invention discloses a modularized dynamic gas purification tower which comprises a slag collecting tank and a base, wherein one or a plurality of horizontally placed reaction kettles are arranged on the base; the gas circuit connection between reaction kettles is realized through a gas guide pipe; each reaction kettle comprises a reaction kettle shell, a filling box, a sealing ring, a rotating shaft, a bearing base, a liquid draining pipe, a driving wheel, a feeding hole, a dosing pipe and a discharging hole. The modularized dynamic gas purification tower disclosed by the invention can select the assembling quantity of the reaction kettles and the type of the filling material according to the purification treatment requirements for the specific gas type; the modularized dynamic gas purification tower is flexibly used and is suitable for the purification treatment of different types of gases; the reaction kettles are horizontally placed and can be rotated along the axis; the static stacking state of the filling material in the conventional tower can be changed and the filling material can freely move and collide in the reaction kettles, so that the defects of caking, bias flow, flooding and crystallizing can be avoided.

Description

technical field [0001] The invention relates to the technical field of purification and treatment devices for industrial multi-component gas and dusty high-temperature gas, in particular to a modular dynamic gas purification tower. Background technique [0002] In all coal-fired power plants, coking plants, petroleum coke calcination kilns, silicate plants, smelters and other industrial and mining enterprises in the world, desulfurization, denitrification, dust removal and cooling in flue gas treatment are not easy to deal with . Because most of these factories have very large waste gas volumes, ranging from hundreds of thousands to hundreds of thousands of m3 / h, many technologies that are handy for small-volume desulfurization and denitrification appear to be extremely expensive to operate in the air volume of these plants. Unbearable (such as ammonia method, ammonia water catalytic method, zinc oxide method, sodium anthraquinone disulfonate method, cobalt molybdenum hydro...

Problems solved by technology

[0010] The lime-gypsum method is a successful low-cost technology for treating high-temperature atmospheric waste gas containing sulfur, nitrate, and dust, but severe crystallization makes users in endless maintenance such as descaling, dredging, changing pipes, and pumps Among them; the packed tower is excellent in dealing with gas-liquid mass transfer, but no one dares to use it in the case of crystallization everywhere; activated coke is a good material for desulfurization and denitrification, but the lime-gypsum process is easy to use in equipment Calcium dioxide crystals are formed on the surface to cover up the active coke, and the effect of the active coke cannot be exerted
