Problems solved by technology
[0007] In the actual production process, the elemental sulfur generated in the solution is easy to deposit at the bottom of the regeneration loop to form sulfur paste, thus affecting the regeneration effect
Moreover, the deposited sulfur paste will cause serious corrosion to equipment such as regenerative ring pipes, which will affect the long-term operation of equipment and bring potential safety hazards

Abstract
The invention provides a regeneration system of a desulfurizing liquid, a desulfurizing system, and a desulfurizing method. The regeneration system includes: a regeneration circular pipe; a regeneration ejector of which the liquid inlet is communicated with the regeneration circular pipe; and a regeneration trough communicated with the outlet of the regeneration ejector. The regeneration ejector includes: an inverted U-shaped liquid inlet pipe and a body, wherein one end of the inverted U-shaped liquid inlet pipe is a liquid inlet end while the other end is a liquid outlet end; a nozzle is formed on the liquid outlet end; the liquid inlet end is stretched into the regeneration circular pipe through the top thereof; and the liquid outlet end is fixed in the body. An outlet of the body is communicated with the regeneration trough. By means of the structure, the regeneration system can effectively prevent accumulation of sulfur paste on the bottoms of the regeneration circular pipe and the regeneration trough, thus alleviating corrosion on the device, guaranteeing long-period normal operation of the regeneration system and further improving desulfurizing efficiency.
Description
technical field [0001] The invention relates to the technical field of desulfurization, in particular to a desulfurization liquid regeneration system, a desulfurization system and a desulfurization method. Background technique [0002] With the shortage of oil and natural gas resources in our country and the change of relevant national policies, the coal chemical industry in my country has developed rapidly in recent years. Sulfur is a widely involved component in coal chemical industry. No matter its content is high or low, it will produce certain toxic effects. Therefore, desulfurization has become an important process in the field of coal chemical industry. [0003] At present, the most commonly used desulfurization process is wet oxidation desulfurization, which mainly removes sulfur from coal gas, coke oven gas or natural gas. Generally speaking, the desulfurization system can be divided into two major subsystems: desulfurization and regeneration. The desulfurization l...
