Shaftless fluid reactors and device for desulfurizing sulfurous gas through slurry method

Abstract

The invention discloses shaftless fluid reactors and a device for desulfurizing sulfurous gas through a slurry method, and relates to the technical field of chemical equipment. The invention aims at solving technical problems to provide the shaftless fluid reactors which can realize automatic mixing of fluid and are beneficial for sufficient reaction of the fluid, and each shaftless fluid reactoris characterized by comprising a shell and a rotation body, the inside of the shell is a cavity with a circular cross section, at least one rotation body is arranged inside the shell, the rotation body can rotate relative to the shell, a fluid passage is formed inside the rotation body in the axial direction, and at least one coil of helixes are arranged in the fluid passage. The fluid enters fromthe entry end of the shell and pushes the helixes to drive the rotation body to rotate relative to the shell when passing through the fluid passage, and the fluid is stirred and mixed to be in full contact to react. The device for desulfurization through the slurry method comprises the shaftless fluid reactors, a feed gas separating tank, a slurry gas separating tank and pipelines. The inventionis suitable for desulfurization of the sulfurous gas through the slurry method.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a reactor which facilitates the full contact reaction of fluids, and a device for desulfurizing gas by a slurry method. Background technique [0002] Slurry desulfurization technology, also known as SDT slurry method or slurry method, can achieve highly selective and efficient removal of hydrogen sulfide in sulfur-containing gases. The agent used in slurry desulfurization is "amorphous iron oxyhydroxide (Amor-FeOOH)". The desulfurization and regeneration principle of iron oxyhydroxide (FeOOH) is: the sulfur capacity of iron oxyhydroxide is large, and hydrogen sulfide H 2 The sulfur-iron compound generated by the S reaction is iron mercaptosulfide (FeSSH), and the generated iron mercaptosulfide is oxidized and regenerated by oxygen to be converted into iron oxyhydroxide, and elemental sulfur is precipitated at the same time. The regenerated ferric oxyhydroxide is recy...

Problems solved by technology

Due to fluctuations in the hydrogen sulfide content in the sulfur-containing gas, the reaction path of the existing absorption tower is short, and the problem of insufficient reaction between the sulfur-containing gas and the desulfurization agent is prone to occur, and it is not convenient to carry out the desulfurization process according to the content of hydrogen sulfide in the sulfur-containing gas. Adjustment, resulting in the problem that the desulfurization does not meet the standard
