specific Embodiment 1

[0071] Such as Figure 2 to Figure 5 As shown, the sulfur wet molding system includes a water tank for holding process water and a process water pH adjustment device. The process water pH adjustment device can detect the pH value of the process water in the water tank in real time, and precisely control the inflow according to the pH value. The amount of lye in the water tank, so that the pH value of the process water is always kept in an appropriate range during the production process, prevents corrosion of equipment and pipelines, prolongs the service life of the sulfur wet molding system, and can improve the overall sulfur wet molding The operation stability of the system improves the molding quality of sulfur granules and ensures production.

[0072] Such as figure 2 As shown, the process water pH adjustment device mainly includes a liquid storage tank 1, a pH detector 9, a control cabinet 7, and a liquid injection pipeline 19. The liquid storage tank 1 is used to store ...

Embodiment 1

[0101] In Example 1, the lye is formed by adding alkaline substances and water into the liquid storage tank and stirring. In the present embodiment, in actual use, also can buy the lye prepared on the market.

specific Embodiment 3

[0103] In Embodiment 1, a diaphragm metering pump is used to realize the precise delivery of lye. In this embodiment, a plunger or piston type metering pump can be used.

Abstract

The invention relates to the field of sulfur wet forming, in particular to a sulfur wet forming system which comprises a water tank used for containing process water, a liquid storage tank used for storing alkali liquor, a pH detector used for detecting the pH value of process water in the water tank, a liquid injection pipeline connected to the liquid storage tank and a controller. The liquid injection pipeline is used for injecting the alkali liquor in the liquid storage tank into the water tank, and is provided with a metering pump. The controller is used for controlling the metering pump to be opened or closed according to a detection value of the pH detector. According to the sulfur wet forming system, the pH value of process water is always kept in a proper range in the production process, equipment and pipelines are prevented from being corroded, the service life of the sulfur wet forming system is prolonged, and the forming quality of sulfur particles is improved.

Description

technical field [0001] The invention relates to the field of sulfur wet molding, in particular to a sulfur wet molding system. Background technique [0002] The sulfur wet briquetting system is currently the mainstream large-capacity sulfur briquetting device in China, and is used in sulfur recovery in natural gas purification, oil refining, and coal chemical industries. The sulfur wet molding system in the prior art is shown in the Chinese invention patent whose authorized announcement number is CN105129740B, specifically as figure 1 As shown, the sulfur wet molding system includes a molding tray 100, a molding tank 200, a static curved screen 300, a vibrating dewatering screen 400, a sedimentation tank 500, a water tank 600 and a heat exchanger 700, wherein the molding tank 200 has a water inlet and an outlet The water inlet, the water inlet and the water outlet are all connected to the water tank 600 so that the process water can circulate. The heat exchanger 700 is arra...
