Embodiment 1

[0033] refer to figure 1 , a sulfur particle separation system, belonging to the technical field of waste gas purification treatment in the field of viscose fiber production, comprising a sulfur slurry settling tank 1, a desander I2, a plate and frame filter 3, a desalinated water tank 4 and a flushing tank 5, said The sulfur slurry settling tank 1 and the desander I2 are connected by a pipeline, and the pipeline is provided with a sulfur slurry pump 6, and the inlet and outlet ends of the sulfur slurry pump 6 are respectively provided with No. 9 valve 27 and No. 8 valve 26; No. 10 valve 29 is provided at the outlet of sulfur slurry settling tank 1. The outlet at the upper end of the desander I2 is connected to the desulfurizer recovery pipeline 7. The outlet at the upper end of the desander I2 is provided with a No. 21 valve 40. The outlet of the lower end of the sander I2 is connected with a tailings tank 8; the tailings tank 8 is connected to the plate and frame filter 3 th...

Embodiment 2

[0051] Compared with Example 1, the present embodiment differs in that in step E, when the liquid level is full, close the No. 1 valve 19 and No. 2 valve 20, open the No. 19 valve 38, and keep circulating for 30 minutes; in step F, After the flushing tank 5 is full, close No. 1 valve 19 and No. 2 valve 20, open No. 19 valve 38, and keep circulating for 30 minutes.

Abstract

The invention discloses a sulfur granule separation system and method and belongs to the technical field of waste gas purification treatment in viscose production. A sand removing device is additionally mounted and is mounted in a specific assembling mode, the technology process of the whole system is controlled through valves, the system and the method are combined and optimized with conventionalsulfur granule washing and recycling modes, the problems that in the prior art multiple plate frame type filter presses and conveying pumps need to be mounted, a large floor space is needed, the investment cost is high, the operation process is complex, and process control is obstructed can be solved, sulfur granules can be washed cleanly, the cost can be lowered, and process control can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of waste gas purification treatment in the field of viscose fiber production, and in particular relates to a sulfur particle separation system and method. Background technique [0002] Viscose fiber is a regenerated fiber with excellent performance comparable to natural fibers and synthetic fibers. At present, the production of viscose fiber generally adopts alkaline sulfonation glue making and acid coagulation molding methods, and the CS produced in the production process 2 、H 2 Harmful gases such as S are extremely harmful to the human body, so it is necessary to strictly control the CS in the production environment 2 、H 2 For the S content, TRS complex iron desulfurization catalyst is used to make use of the redox property of complex iron ions in aqueous solution to make gas-liquid phase contact reaction between gas containing hydrogen sulfide and the aqueous solution containing complex iron catalyst...
