Abstract

The invention provides an oxidation-absorption supergravity desulfurization and denitrification system and method. The system is composed of a medicament feeding device and a supergravity reactor, the medicament feeding device comprises a medicament pool, a medicament liquid outlet of the medicament pool is connected with an outlet of a medicament adding pump, and an outlet of the medicament adding pump is connected with a medicament inlet of the supergravity reactor; the supergravity reactor comprises a shell, an annular filler rotor is arranged inside the shell, a gas inlet, a gas outlet, a medicament inlet and a medicament outlet are arranged on the shell, the gas outlet is connected with an induced draft fan, and the medicament outlet is connected with a backflow port of the medicament pool. The method includes: preparing a potassium monopersulfate solution of 0.1-1% in mass concentration; constantly guiding the potassium monoperfulfate solution into the inside of a filler of the annular filler rotor of the supergravity reactor, guiding dedusted mixed smoke into the supergravity reactor, and controlling the annular filler rotor to rotate at a constant speed to desulfurize and denitrify the mixed smoke; controlling flow velocity of a gas adjusting valve, and discharging desulfurized and denitrified smoke.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an oxidation-absorption supergravity desulfurization and denitrification system and method. Background technique [0002] In 2013, the State Council issued three consecutive documents on the issue of energy conservation and emission reduction: "Ten Measures for Air Pollution Prevention and Control", "Opinions of the State Council on Accelerating the Development of Energy Conservation and Environmental Protection Industries" and "Action Plan for Air Pollution Prevention and Control". put forward higher requirements. [0003] At present, the methods for treating nitrogen oxides and / or sulfides at home and abroad mainly include: selective non-catalytic reduction method (SNCR), selective catalytic reduction method (SCR), high-energy electron activation oxidation method, solution absorption method, oxidation absorption method, biological treatment, etc. Non-selectiv...
