Russian Application of the Gasketed Filter Press in Filtering Methanol Materials
Due to its volatility and toxicity, methanol needs to be strictly controlled during processing to ensure the safety of the operating environment and the health of operators. As high-efficiency solid-liquid separation equipment, the gasketed filter press is widely used in the filtration of methanol materials due to its excellent sealing and processing effect. The following is the specific application of the gasketed filter press in filtering methanol materials.
Hazards of Methanol
Methanol is a colorless, transparent, flammable, volatile toxic liquid. It is one of the important raw materials for pesticides and medicines. However, in actual operation, methanol will volatilize and have a greater impact on the human nervous system and blood system after inhalation. It will produce toxic reactions when ingested through the digestive tract, respiratory tract, or skin, and can damage the respiratory mucosa and vision of the human body.
The Specific Application Process of Gasketed Filter Press
Preparation before filtration
Before starting the equipment, check whether the filter plate, filter cloth, and seal are intact to ensure that the sealing performance of the equipment meets the process requirements and prevents the volatilization and leakage of methanol materials. According to the particle size, viscosity, and corrosiveness of the methanol material, select a filter cloth with corrosion resistance and moderate water permeability to ensure separation efficiency and durability. Set the filtration pressure, temperature,e and time through the automatic control panel to ensure that it meets the material separation requirements.
Material feeding
Start the feed pump to deliver the methanol material to the feed port of the filter press. The feed needs to be kept uniform to prevent damage to the filter plate or filter cloth due to uneven pressure. The material is initially filtered through the filter cloth and filter plate, and the filtrate flows into the drainage channel of the equipment, while the solids are trapped in the filter chamber.
Filtration process
After the hydraulic system is started, the filter plate is compressed to form a closed filter chamber to prevent the leakage of liquid or gas during the filtration process. Under the set pressure, the filter medium separates the liquid and solid, and the filtrate flows out of the equipment through the filter cloth. For methanol materials, the filtrate can be recovered or further processed. The filtration pressure is monitored in real time to ensure that the separation process is smooth and to avoid equipment failure or material volatilization due to overpressure.
Filter cake processing
After the filtration is completed, the automatic plate-pulling system is started and the filter cake is automatically discharged from the filter chamber. The filter cake of methanol materials can be safely handled or recycled according to the process requirements. Use high-pressure water or other cleaning methods to clean the filter cloth to prevent the filter cloth from clogging and affecting the subsequent filtration efficiency.
Advantages of Gasketed Filter Press
Strong sealing
The gasketed filter press uses gasketed filter cloth, which is embedded in the filter chamber of the filter plate with a rubber ring. A sealing ring is added to the sealing surface of the filter plate to enhance the sealing between the filter plates and avoid liquid leakage. It can effectively prevent methanol materials from leaking or volatilizing during the filtration process and causing environmental pollution. In addition, its sealing structure can also ensure the collection and discharge of gases during the treatment process, further reducing the impact on air quality.
High production efficiency
The gasketed filter press adopts optimized filter media and a hydraulic clamping system, which can quickly achieve solid-liquid separation. For methanol materials, the filtration accuracy and dehydration efficiency are particularly important. The equipment can ensure the clarity of the filtrate and reduce the amount of methanol residue in the filter residue for subsequent processing.
High corrosion resistance
Methanol and its processed materials are corrosive to a certain extent. Gasketed filter presses are usually made of stainless steel, polypropylene, or other corrosion-resistant materials. The filter cloth and filter plate are specially treated to adapt to highly corrosive environments for a long time and reduce equipment loss.
Conclusion
The gasketed filter press performs well in filtering methanol materials. Its excellent sealing, high efficiency, and automation make it an ideal choice for handling volatile and highly toxic materials. By using this equipment scientifically, it can not only improve production efficiency, but also effectively reduce environmental pollution and health hazards, and promote chemical companies to achieve green production goals.
