The reaction between sulfuric acid and phosphate ore powder is a crucial process in the production of phosphate fertilizers. This reaction produces phosphoric acid, which is a key component in the production of various phosphate based fertilizers. In order to achieve optimal efficiency and safety in this process, high-quality reaction vessels are essential. LANE Group’s sulfuric acid and phosphate ore reactors are designed specifically to handle this demanding process, ensuring precise control, safety, and high productivity.

Composition structure

Kettle body: The main body of a reaction kettle is usually made of stainless steel materials such as SUS304 or SUS316L, which can resist the corrosive effect of sulfuric acid.

Stirring device: including a stirrer and a stirring shaft, used to accelerate the reaction process between sulfuric acid and phosphate powder, ensuring thorough mixing of materials.

Heating and cooling system: usually adopts structures such as jacket, coil or half tube, which can control the reaction temperature through steam, hot water or cooling water.

Sealing device: To ensure the sealing of the reaction vessel under high pressure or high temperature conditions, mechanical seals or packing seals can be used.

Transmission device: composed of a motor and a reducer, providing the power required by the mixer.

Control system: used to monitor and adjust parameters such as temperature, pressure, and stirring speed during the reaction process.

Working principle

Reaction process: Sulfuric acid and phosphate powder are added to the reaction kettle in a certain ratio (usually 2.5:1), and the temperature is controlled at around 75 ℃ for about 3 hours during the reaction process. This process is mainly carried out continuously in four tanks inside the reaction kettle, with a reaction time of 3 hours for each tank to ensure sufficient reaction.

Heat and mass transfer: The reactor is equipped with a jacket and a heat exchange surface inside, which achieves efficient heat and mass transfer through liquid-phase circulation or gas-phase reflux, making the reaction more uniform and complete.

Advantage

Efficient continuous production: Due to the use of continuous production methods, the time for cooling and heating is saved, and continuous production can be carried out for 24 hours without interruption, significantly improving production efficiency.

Energy saving and environmental protection: The design of the reactor takes into account environmental protection and energy conservation, equipped with sealing technology and heat recovery system to reduce heat loss and exhaust emissions, while treating the flue gas to achieve standard emissions.

Automated control: By adopting an automated control system, operators can easily monitor the entire carbonization process, reducing operational difficulty and maintenance costs.

In summary, the sulfuric acid phosphate powder reaction kettle not only plays an important role in the process, but its design and material selection also have a direct impact on the efficiency and safety of the entire production process. This efficient reaction equipment is widely used in modern chemistry and mineral processing industries, and has broad development prospects.
