The paint mist filter box achieves high-precision purification and effectively ensures the workers' breathing health through multi-stage filtering structure, high-efficiency filtering materials, reasonable airflow design, and intelligent monitoring and maintenance.Multi-stage filtering structurePrimary filtration intercepts large particles: The paint mist filter box usually sets a primary filter layer, generally using a metal mesh or a coarse filter. These primary filter layers can initially intercept paint mist particles and impurities with larger diameters in the exhaust gas, prevent large particles from directly entering the subsequent filtration system, reduce the burden of the subsequent filter layer, and extend its service life.Medium-efficiency filtration further purifies: The exhaust gas after the primary filtration enters the medium-efficiency filter layer, which is generally made of materials such as synthetic fibers or glass fibers. It can further filter out smaller paint mist particles in the exhaust gas, improve the filtering accuracy, and significantly reduce the paint mist content in the exhaust gas.High-efficiency filtration achieves deep purification: The high-efficiency filter layer is the key part of the paint mist filter box to achieve high-precision purification, and usually uses high-efficiency filter materials such as HEPA (high-efficiency air filter) or ultra-fine glass fiber filter paper. These materials can filter particles with a diameter of more than 0.3 microns with a filtration efficiency of more than 99.97%, which can effectively remove tiny paint mist particles and harmful substances in the exhaust gas, ensuring that the discharged air meets high cleanliness standards.High-efficiency filter materialsHigh adsorption performance: Some paint mist filter boxes use filter materials with high adsorption performance, such as activated carbon fiber, zeolite, etc. These materials can adsorb harmful substances such as organic solvents and odors in the exhaust gas, further purify the air and improve the air quality.Flame retardant and corrosion resistant: Considering the particularity of the spray workshop environment, the filter material needs to have flame retardant and corrosion resistance. Flame retardant properties can prevent the filter material from burning under high temperature or open flames, causing safety accidents; corrosion resistance can ensure that the filter material is not easily damaged when it comes into contact with chemicals such as paint and solvents, extending its service life.Reasonable airflow designUniform airflow distribution: The paint mist filter box has a reasonable airflow channel designed inside, so that the exhaust gas can pass through the filter layer evenly. Uniform airflow distribution can avoid excessive load on the local filter layer, improve the overall filtration efficiency, and ensure that each part of the filter material can fully play its role.Low resistance design: Under the premise of ensuring the filtering effect, optimize the airflow path and reduce the resistance of airflow through the filter layer. Low resistance design can reduce fan energy consumption, reduce equipment operating costs, and reduce the risk of paint mist escape caused by excessive airflow resistance.Intelligent monitoring and maintenanceReal-time monitoring of filtering effect: Modern paint mist filter box is equipped with sensors and monitoring systems, which can monitor the pressure difference inside and outside the filter box, paint mist concentration and other parameters in real time. When the filtering effect drops to a certain level, the system will issue an alarm in time to remind the operator to perform maintenance or replace the filter material.Automatic cleaning and regeneration: Some advanced paint mist filter boxes have automatic cleaning functions, which can regularly clean the filter material, remove the paint mist particles attached to the surface, and restore the filtering performance. In addition, some filter materials also support regeneration processing, which restores their adsorption capacity through specific processes and reduces the cost of use.Maintenance and careRegularly replace filter materials: According to the service life of the filter material and the actual filtering effect, regularly replace the primary, medium and high efficiency filter layers to ensure that the filter box always maintains good filtering performance.Clean the inside of the equipment: Clean the inside of the paint mist filter box regularly to remove accumulated dust and impurities to prevent blockage of the airflow channel and affect the filtering effect.Check the operating status of the equipment: Regularly check the operating parameters of the equipment, such as air volume, air pressure, temperature, etc., to ensure the normal operation of the equipment. If any abnormality is found, repair and adjust it in time.
