Description

Super gravity dust removal, desulfurization and denitrification device

This creation provides a technical field of dedusting, desulfurization and denitrification, in particular, it technically provides a device for super-gravity desulfurization, desulfurization and denitration, which allows the addition of a multi-bar stator single-rotation super The gravity rotating bed cooperates with ozone and liquid alkali to make the purified gas comply with emission standards.

According to the press, the dust, SOx and NOx generated in the boiler combustion process will cause serious harm to the environment and humans. With the strengthening of people's awareness of environmental protection, the requirements of boiler flue gas purification are becoming more and more stringent. During the combustion of coal, a lot of pollutants such as dust, SOx and NOx will be produced. SOx and NOx emissions will not only cause acid rain and acid mist, but also cause serious harm to humans, animals and plants, but also destroy the ozone layer and cause global warming. Dust contains large amounts of heavy metals and chemical carcinogens, which can cause pneumonia, lung cancer and flu. Industrial boilers are important sources of atmospheric pollutants except for thermal power plant boilers. The quantity of coal-fired boilers in my country is large and wide. These boilers have low energy efficiency and serious pollution. Therefore, the development and research of boiler flue gas purification technology has important environmental protection significance.

Dust removal, desulfurization and denitrification staged treatment, the dust removal device-spray dust removal device or electrostatic dust removal device, desulfurization device-limestone/gypsum wet flue gas desulfurization (wet fluegas desulfurization, WFGD) and denitration device one Selective catalytic reduction (SCR) is connected in series to achieve the purpose of dust removal, desulfurization and denitrification. The step removal technology has high removal efficiency of pollutants and a wide range of application, but it has the disadvantages of large area, high operating cost and demanding operating conditions. Flue gas dedusting, desulfurization and denitrification technologies can be divided into three types: wet method, semi-dry method and dry method. Domestic integrated technology for boiler dust removal, desulfurization and denitration has not yet been economically effective. Some boilers use the wet three-machine integrated technology for dust removal, desulfurization and denitrification. This technology uses the method of oxidation before absorption, that is, using strong oxidants such as NaClO ₂ , H ₂ O ₂ , KMnO ₄ solution and O ₃ gas. The low-valence NOx is oxidized to the high-valence NOx, and then absorbed by liquid alkali, so as to realize the dust removal, desulfurization and denitrification of flue gas at the same time. The wet process integration technology has a wide application range, simple operation, and relatively low investment cost, and is particularly suitable for the purification of small and medium boiler flue gas. However, because the flue gas purification technology usually uses traditional scrubber equipment, the mass transfer efficiency is low and the pollutant removal rate is relatively low.

Therefore, how to develop a more ideal and practical innovative structure in response to the problems of the above-mentioned conventional structure is what consumers are eagerly expecting, and it is also the goal and direction of the relevant industry to work hard to develop breakthroughs.

In view of this, the creator has many years of experience in the manufacturing development and design of related products. In view of the above goals, after detailed design and careful evaluation, he finally has a practical original creation.

The main purpose of this creation is to provide a device for supergravity dust removal, desulfurization and denitrification, which can add ozone to oxidize low-valent nitrogen to high-valent nitrogen, and then use the multi-rod stator single-rotation ultra-high mass transfer, small volume and large processing capacity. Gravity rotating bed combined with liquid alkali absorbent to make the purified gas meet the emission standards.

In order to achieve the above purpose, this creation provides a device for degraving, desulfurization and denitrification by super-gravity, which includes: a flue gas inlet pipe must be fully mixed with ozone to oxidize low-priced nitrogen into high-priced nitrogen, and then a fan The gas inlet is fed into the multi-rod stator single-rotation super-gravity rotating bed; a liquid storage tank contains the diluent alkali, and then it is sent to the multi-rod stator single-rotation super-gravity rotating bed through the liquid inlet through a liquid pump. The stator of the single-rotor super-gravity rotary bed with multiple rods is fixed, and the rotor must be driven by the power device to rotate at high speed, so that the gas and liquid can be fully mixed and cut into micron droplets, so that the mass transfer efficiency is greatly improved. The high mass transfer absorption effect of the alkali absorbent micron droplets achieves the effects of dust removal, desulfurization and denitrification (denitrification, which produces nitrate due to nitrogen and water), so that the discharged gas meets the emission standards, and the treatment effect of pollutants is more Good, higher ozone utilization rate, small size of equipment, lower cost than washing tower, large processing capacity, etc., effectively protect environmental safety and ensure human health.

Regarding the techniques, methods and functions used in this creation, I will give a preferred embodiment and detailed descriptions in conjunction with the drawings. I believe that the above-mentioned purposes, structures and features of this creation can be obtained from an in-depth and specific understanding .
