BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 This is a schematic structural diagram of the utility model.

DETAILED DESCRIPTION

[0018] like Figure 1 As shown, an intelligent liquid sulfur metering and feeding control device includes a liquid sulfur pool 6, a liquid sulfur metering tank 9, and a reactor 12. Liquid sulfur pipes A13 and B14 are installed between the liquid sulfur pool 6 and the liquid sulfur metering tank 9. Liquid sulfur pump A4 directs liquid sulfur from the liquid sulfur pool 6 to the liquid sulfur metering tank 9 through liquid sulfur pipe A13. Liquid sulfur pipe B14 returns excess liquid sulfur in the liquid sulfur metering tank 9 to the liquid sulfur pool 6 (the outlet of liquid sulfur pipe B14 is located at the upper edge of the liquid sulfur metering tank 9). Liquid sulfur pump B7 directs liquid sulfur to the reactor 12 through liquid sulfur pipe C15. A feed valve 11 is installed on liquid sulfur pipe C15.

[0019] The liquid level meter 8 (connected by a wire 16) is provided on the liquid sulfur metering tank 9 and is used to simultaneously interlock and control the liquid sulfur pump A4, the liquid sulfur pump B7 and the feed valve 11 of the reactor 12. The feed valve 11 is provided on the liquid sulfur pipe C15.

[0020] A coil 5 is installed within the liquid sulfur pool 6. Steam is introduced into the coil through a steam inlet 1 to heat the liquid sulfur within the pool. A temperature controller 3 is installed within the pool 6. This temperature controller automatically controls the opening and closing of a steam inlet valve 2 based on the temperature of the pool 6. When the temperature drops to a critical value, the steam inlet valve 2 is opened to allow steam to be introduced for heating. After the liquid sulfur within the pool 6 is heated to a predetermined temperature, it is pumped to a liquid sulfur metering tank 9 via a liquid sulfur pump A4.

[0021] The liquid sulfur metering tank 9 is jacketed, and steam is introduced into the jacket through steam inlet 10 to heat the liquid sulfur in the tank. Liquid sulfur pump A4 transfers liquid sulfur from the liquid sulfur pool 6 to the liquid sulfur metering tank 9. Because liquid sulfur pump A4 is interlocked with liquid level gauge 8, it stops when the liquid sulfur in the tank 9 reaches the set level.

[0022] A reflux pipe (liquid sulfur pipe B14) is installed on the liquid sulfur metering tank 9, providing dual protection along with the liquid level gauge 8 to prevent overflow. The top of the liquid sulfur metering tank 9 (the height of the liquid level when full) is higher than the top of the liquid sulfur pool 6 (the height of the liquid level when full). One end of the liquid sulfur pipe B14 is located at the top edge of the liquid sulfur metering tank 9, while the other end is located within the liquid sulfur pool 6. This allows excess liquid sulfur to flow back directly by gravity.

[0023] Liquid sulfur pump B7 directs liquid sulfur from liquid sulfur metering tank 9 into reactor 12. It is interlocked with liquid level gauge 8 and the feed valve of reactor 12. When the amount of liquid sulfur in reactor 12 reaches the set amount (i.e., the amount set by the liquid level gauge), feed valve 11 closes, and liquid sulfur pump B7 stops operating. This dual interlocking of feed valve 11, liquid sulfur pump B7, and liquid level gauge 8 ensures accurate control of the amount of liquid sulfur delivered to reactor 12.

[0024] The liquid sulfur pipe A13, liquid sulfur pipe B14 and liquid sulfur pipe C15 are casing pipes, and steam is introduced into the casing pipes for heating to keep the liquid sulfur in the liquid sulfur pipes A13, liquid sulfur pipe B14 and liquid sulfur pipe C15 warm.

[0025] The reactor 12 is provided with an interlayer for heat preservation of liquid sulfur.

[0026] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
