Embodiment Construction
[0017] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] Such as figure 2 Shown: Take the desulfurization regeneration tower for desulfurization of gas containing sulfide such as hydrogen sulfide as an example. The lower part of section 12 is fed with desulfurized gas 13 containing sulfide such as hydrogen sulfide, and the upper part of washing section 12 is sprayed with desulfurization liquid 14 to absorb sulfide in gas 13 . The washed desulfurized gas 15 passes through the upper part of the washing section and is equipped with a mist trapping device 16 to remove the entrained liquid droplets, and then enters the descending pipe 17 arranged along the axis of the washing section of the desulfurization regeneration tower. The supporting part 19 with sealing function, the desulfurized gas 15 is exported to the scrubbing section 12 of the desulfurization regeneration tower throu...

The invention discloses a desulfurizing tower for gas desulfuration by liquid phase catalytic oxidation. The lower part of the washing segment of a desulfurizing tower is provided with an inlet for gas to be desulfurized, and the upper part of the washing segment of the desulfurizing tower is provided with a doctor solution spraying part. The desulfurizing tower is characterized in that a descending pipeline causing desulfurized gas to pass is arranged along the axis of the washing segment of the desulfurizing tower, and the top of the washing segment of the desulfurizing tower is provided with an entrainment capturing device and is communicated with a horizontal pipeline which can lead the desulfurized gas out of the lower part of the washing segment of the desulfurizing tower. The desulfurizing tower of the invention has simple structure and good stability and is easy to manufacture and install. The structure that sulfurous gas enters or leaves the desulfurizing tower is more reasonable, which is favourable for the even distribution of desulfurized gas which enters or leaves the desulfurizing tower; the entrainment capturing device arranged on the top reduces entrainment, is favourable for lowering tower height and is favourable for reducing the equivalent diameter of the washing segment of the desulfurizing tower so as to bring convenience for reducing amplification effect and improve desulfurizing efficiency; a vertical heavy-calibre gas pipeline which is connected out of the upper part of the washing section is cancelled, namely eccentric load, wind load and the like which are unfavorable for the desulfurizing tower are cancelled.
Description
technical field [0001] The invention belongs to the technical field of desulfurization, and in particular relates to a desulfurization tower for desulfurizing gas containing sulfide such as hydrogen sulfide by a liquid-phase catalytic oxidation method. Background technique [0002] In the past, the typical devices for desulfurization of gas containing hydrogen sulfide and other sulfides by liquid-phase catalytic oxidation method include desulfurization tower, liquid seal tank, reaction tank, liquid level regulator, regeneration tower (or use jet regeneration tank instead of regeneration tower) And other equipment, there are many unit operation equipment, large floor area, high project investment, high power consumption, and heavy secondary pollution. [0003] In recent years, a tower-type desulfurization process device has been adopted, that is, a desulfurization regeneration tower integrating desulfurization and regeneration. environmental pollution. [0004] However, whe...
