Description

Technical Field

[0001] This utility model relates to the field of dilute sulfuric acid technology, specifically to a neutralization tank for dilute sulfuric acid neutralization treatment. Background Technology

[0002] Dilute sulfuric acid typically refers to an aqueous solution of sulfuric acid with a concentration of less than 30%. It is highly acidic and corrosive, and readily reacts with metals and alkaline substances to form sulfates. Direct discharge of dilute sulfuric acid will disrupt the pH of water bodies and harm the ecological environment. Therefore, it is necessary to use dilute sulfuric acid neutralization treatment equipment to neutralize dilute sulfuric acid so that the neutralized dilute sulfuric acid meets the discharge standards.

[0003] However, existing dilute sulfuric acid neutralization equipment has a simple structure and lacks a structure that facilitates the disassembly and assembly of the stirring blades, affecting the efficiency of disassembly and assembly. Moreover, it does not have the function of collecting the calcium sulfate produced during neutralization, wasting the neutralization product that could be recycled and reused, resulting in a poor neutralization effect. Therefore, we propose a neutralization tank for dilute sulfuric acid neutralization treatment. Utility Model Content

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To facilitate the disassembly and assembly of the stirring blades, improve disassembly and assembly efficiency, and simultaneously collect the calcium sulfate produced during neutralization, thereby enhancing the neutralization treatment effect, such as... Figure 1-6 As shown, the neutralization tank for neutralizing dilute sulfuric acid according to this utility model includes a base 1, a neutralization tank 2, a neutralization pool 3, a filter cartridge 8, a stirring blade A14, and a stirring blade B18. The neutralization tank 2 is installed at one end of the top of the base 1. A liquid inlet channel 21 is provided at the upper end of one side of the neutralization tank 2. A side door 11 is installed on the other side of the neutralization tank 2 by bolts. A stirring rod 13 is provided inside the neutralization tank 2. Stirring blade A14 and stirring blade B18 are respectively installed at the upper and lower ends of the outer side of the stirring rod 13. An arc-shaped mounting plate A17 is provided at the end of the stirring blade A14 near the stirring rod 13, and an arc-shaped mounting plate B19 is provided at the end of the stirring blade B18 near the stirring rod 13.

[0032] The other end of the top of the base 1 is fixed with a neutralization tank 3. A servo motor 4 is installed on the top of the neutralization tank 2. A liquid outlet pipe 5 is provided at the lower end of one side of the neutralization tank 2. A liquid inlet pipe 6 is provided on one side of the top of the neutralization tank 3. A magnetic drive pump 16 is installed on one side of the neutralization tank 3 by screws. An inclined guide plate 7 is installed at the bottom inside the neutralization tank 3. A filter cartridge 8 is installed on one side of the top inside the neutralization tank 3.

[0033] During use, both stirring blades A14 and B18 are detachably connected to stirring rod 13 via arc-shaped mounting plates A17 and B19, which facilitates the inspection or replacement of stirring blades A14 and B18 and effectively improves the convenience of disassembly and assembly as well as work efficiency.

[0034] After neutralization, the dilute sulfuric acid can enter the neutralization tank 3 through the outlet pipe 5, the magnetic drive pump 16 and the inlet pipe 6. Before entering the neutralization tank 3, the dilute sulfuric acid containing calcium sulfate flows through the filter cartridge 8. The filter cartridge 8 can retain the calcium sulfate, while the dilute sulfuric acid can flow out of the filter cartridge 8 and enter the interior of the neutralization tank 3, so as to achieve the purpose of collecting calcium sulfate.

[0035] The inclined guide plate 7 can guide the flow of dilute sulfuric acid, which can facilitate the smooth entry of dilute sulfuric acid into the interior of the drain pipe 9.

[0036] For example, such as Figure 1 As shown, the upper end of the neutralization pool 3 is provided with a cover plate 23, and the bottom of the cover plate 23 is provided with insert rods 24 around the perimeter. The top of the neutralization pool 3 is provided with slots 25 corresponding to the insert rods 24 around the perimeter.

[0037] In use, personnel can close the cover plate 23 to the neutralization tank 3 through the plug 24 and slot 25. The neutralization reaction may produce bubbles or slight splashes. The cover plate 23 can prevent acid splashes from injuring people or corroding surrounding equipment. Dilute sulfuric acid may contain volatile impurities. At the same time, the cover plate 23 can reduce the diffusion of harmful gases and improve the safety of the neutralization tank for the neutralization treatment of dilute sulfuric acid in this novel way.

[0038] For example, such as Figure 5 As shown, the outlet end of the outlet pipe 5 is connected to the inlet end of the magnetic drive pump 16, the outlet end of the magnetic drive pump 16 is connected to the inlet end of the inlet pipe 6, and the outlet end of the inlet pipe 6 is connected to the filter cartridge 8.

[0039] During use, the dilute sulfuric acid inside the neutralization tank 2 can enter the interior of the neutralization pool 3 through the outlet pipe 5, the magnetic drive pump 16, and the inlet pipe 6.

[0040] For example, such as Figure 1 , Figure 3 , Figure 5 As shown, a drain pipe 9 is provided at the lower end of one side of the neutralization tank 3, and a drain valve 10 is installed on the drain pipe 9.

[0041] In use, the drain valve 10 can control the opening and closing of the drain pipe 9.

[0042] For example, such as Figure 1 , Figure 4 As shown, a positioning mounting seat 12 is provided at one end of the top of the base 1, and the bottom of the neutralization tank 2 is located inside the positioning mounting seat 12.

[0043] During use, the positioning mounting base 12 can stabilize the neutralization tank 2 to improve its stability.

[0044] For example, such as Figure 2 As shown, the bottom of the stirring rod 13 is connected to the inner bottom of the neutralization tank 2 via a bearing 15.

[0045] During use, the stirring rod 13 can rotate smoothly via the bearing 15.

[0046] For example, such as Figure 3 As shown, the top of the filter cartridge 8 is connected to the inner top of the neutralization tank 3 via a connecting plate 22 and bolts.

[0047] During use, the filter cartridge 8 can be disassembled by the connecting plate 22, making it easy to clean or replace the filter cartridge 8.

[0048] For example, such as Figure 1 , Figure 4 As shown, a reserved opening 20 is provided at one end of the base 1.

[0049] When in use, the reserved opening 20 will not obstruct the installation of the drain pipe 9, and it is convenient for personnel to operate the drain valve 10 on the drain pipe 9.

[0050] In use, the operator connects the inlet channel 21 to an external dilute sulfuric acid source to introduce dilute sulfuric acid into the neutralization tank 2. The operator then adds lime and sodium hydroxide alkaline agents into the neutralization tank 2. Four sets of stirring blades A14 and B18 are provided, each detachably connected to the stirring rod 13 via arc-shaped mounting plates A17 and B19, improving ease of assembly and disassembly.

[0051] Furthermore, the servo motor 4 can drive the stirring rod 13, stirring blade A14, and stirring blade B18 to rotate, which can uniformly mix dilute sulfuric acid and alkaline agents and form calcium sulfate neutralization products, thereby achieving the purpose of neutralizing dilute sulfuric acid.

[0052] Furthermore, through the action of the outlet pipe 5, the magnetic drive pump 16 and the inlet pipe 6, the neutralized dilute sulfuric acid can enter the neutralization tank 3. Before entering the neutralization tank 3, the dilute sulfuric acid containing calcium sulfate flows through the filter cartridge 8. The filter cartridge 8 can retain the calcium sulfate, while the dilute sulfuric acid can flow out of the filter cartridge 8 and enter the interior of the neutralization tank 3.

[0053] Furthermore, the inclined guide plate 7 at the bottom of the neutralization tank 3 can guide the flow of the neutralized dilute sulfuric acid, which can facilitate the smooth entry of the dilute sulfuric acid into the interior of the drain pipe 9. When personnel open the drain valve 10 on the drain pipe 9, the neutralized dilute sulfuric acid can be discharged.

[0054] Furthermore, personnel can disassemble the filter cartridge 8 via the connecting plate 22 to facilitate the removal and reuse of calcium sulfate from the filter cartridge 8;

[0055] Furthermore, the neutralization reaction may produce bubbles or slight splashes. The cover plate 23 can prevent acid splashes from injuring people or corroding surrounding equipment. Dilute sulfuric acid may contain volatile impurities. At the same time, the cover plate 23 can reduce the diffusion of harmful gases and improve the safety of the neutralization tank for the neutralization treatment of dilute sulfuric acid in this novel method.
