The new catalytic flue gas desulfurization technology adopts a new low-temperature catalyst to selectively adsorb SO2, H2O and O2 in the flue gas in the micropores of the catalyst under the flue gas discharge temperature of 80~200 °C, through the active components. Catalytic reaction produces H2SO4, which realizes the removal of sulfur dioxide while recovering sulfur resources without secondary pollution. The catalyst is not consumed in the desulfurization process, and it is not necessary to continuously add a desulfurizing agent, and the catalyst life is more than 3 years.

The sodium alkali method is a method of absorbing SO2 in a flue gas using an alkaline substance such as sodium hydrogencarbonate or sodium hydroxide. Depending on the method of regeneration of the absorbing liquid, different sodium-alkali treatment processes can be obtained, and the obtained products are also different. The sodium sulfite method utilizes the difference in solubility of Na2SO3 and NaHSO3 in water to make Na2SO3 crystallize as a product. The sodium sulfite cycle method uses a thermal regeneration method to treat the absorption liquid, and produces a high concentration of SO2 as a by-product, and the absorbent is recycled.

The denitration process employs a selective catalytic reduction process in which a reaction is carried out in a reactor equipped with a catalyst, and the flue gas reacts with the injected ammonia under the action of a catalyst to effect the removal of nitrogen oxides.

The new technology is to make the cyclone into a small-diameter module and to form a unit with multiple swirls. A large flue gas large desulfurization tower is equipped with several or dozens of swirl subunits to achieve good dust removal and defogging effects. In order to ensure that the cyclone does not block, and the outer side wall does not accumulate dust, a water spray device is arranged at the lower swirl center plate, and the outer pipe wall and the swirl plate can be washed regularly or irregularly.

At present, one of the most advanced technologies in industrial waste gas treatment technology, the development of UV photocatalytic equipment fully considers the uncertainty and complexity of industrial waste gas properties, and provides very much from the aspects of engineering design, matching, installation, commissioning and maintenance. Great feasibility, reliability, flexibility and effectiveness.
