Novel internal component and fluidized bed reactor

The invention relates to the technical field of chemical reaction devices, and discloses a novel internal component and a fluidized bed reactor, the novel internal component comprises a guide vane group, the guide vane group comprises a first guide vane and a second guide vane, the first guide vane and the second guide vane are reversely inclined relative to the horizontal plane around a first horizontal axis and reversely inclined relative to the horizontal plane around a second horizontal axis, the first axis is perpendicular to the second axis, and the edges of the first guide vane and the second guide vane intersect at one point. According to the novel inner component formed by the two guide vanes which are relatively twisted and inclined, the guide vanes simultaneously incline around the first axis and the second axis, so that all parts of the main flow surface of the guide vanes have an upward movement trend, and an air cushion is difficult to form below the guide vanes; therefore ...

Flue gas desulfurization and sulfur recovery coupling process and device

The invention relates to a coupling process and device for flue gas desulfurization and sulfur recovery. According to the process, an absorbent is adopted to absorb SO2, an obtained absorption rich solution and H2S-containing gas from a sulfur recovery device are subjected to a liquid-phase Claus reaction in a reactor to generate sulfur, a reaction product is extracted and heated to obtain liquid sulfur to be recovered as a sulfur product, an absorption barren solution enters a stripping tower, and H2S and SO2 dissolved in the absorbent are removed. According to the process, SO2 in the flue gas is removed, SO2 resources are recovered, the yield of sulfur is increased, and the process can be applied to industrial devices for flue gas desulfurization and sulfur recovery. The technological process does not need wastewater and waste gas treatment, the operation stability is high, the overall device investment is reduced, and the yield is increased.
