Desulfurization and denitrification device of sintering machine

Abstract

A desulfurization and denitrification device of a sintering machine comprises a sintering machine, a premixing chamber, a suction channel, an adsorber, a treatment channel, a first ionization field, a cooling tower, a second ionization field, a catalytic reactor and a dispersion tank. The sintering machine and the premixing chamber are connected to the bottom of the premixing chamber through a suction fan. The premixing chamber is fixedly connected with the adsorber through the suction channel. An extending pipeline at the upper end of the adsorber is connected to the inlet end of the first ionization field; the outlet end of the first ionization field is connected with the cooling tower; the outlet end of the cooling tower is connected with the second ionization field; the second ionization field is connected with the inlet end of the catalytic reactor; and the outlet end of the catalytic reactor is connected with the dispersion tank. The premixing chamber is of a rectangular cavity structure and is fixedly connected with an outer shell through bolts, and a first cavity, a second cavity and a third cavity are fixedly arranged in the premixing chamber side by side.

Description

technical field [0001] The invention relates to the technical field of sintering flue gas purification, in particular to a desulfurization and denitrification device for a sintering machine. Background technique [0002] At present, sintering refers to transforming powdery materials into dense bodies. It is a traditional process. People have long used this process to produce ceramics, powder metallurgy, refractory materials, ultra-high temperature materials, etc. The sintering flue gas contains relatively high A lot of dust and sulfide gas, directly discharged into the air will pollute the air, so the flue gas needs to be dedusted and desulfurized before being discharged. The traditional desulfurization and dedusting device will waste a lot of water when using water mist for dedusting, while other dedusting There is also the problem that dust is not easy to clean up in the device.

Problems solved by technology

[0002] At present, sintering refers to transforming powdery materials into dense bodies. It is a traditional process. People have long used this process to produce ceramics, powder metallurgy, refractory materials, ultra-high temperature materials, etc. The sintering flue gas contains relatively high A lot of dust and sulfide gas, directly discharged into the air will pollute the air, so the flue gas needs to be dedusted and desulfurized before being discharged. The traditional desulfurization and dedusting device will waste a lot of water when using water mist for dedusting, while other dedusting The device also has the problem that dust is not easy to clean

[0003] At the same time, the existing desulfurization and denitrification device has carried out selective desulfurization of the flue gas of the sintering machine, which reduces the cost of equipment and use, but it cannot perform synergistic removal of complex pollutants such as NOx, dioxins and heavy metals, and adopts a full-scale Flue gas removal process, high cost

Although the existing equipment can realize the coordinated removal of various acid gases, NOx, heavy metals, dioxins and other compound pollutants in the sintering flue gas, but after the denitrification, the whole flue gas is used for desulfurization and dust removal, so the cost is also high. It is difficult to promote in a large area
