Purification adsorption principle: The cathode tungsten needle in the cylinder honeycomb field emits about 16KV voltage, which turns the fume exhaust molecule into a positive charge particle, which is adsorbed by the surrounding anode tube wall to achieve purification effect. Advantages: Shell using SPCC cold-rolled steel plate film production and high temperature electrostatic spray treatment, beautiful waterproof; The modular cellular electric field yang is extremely 201 stainless steel cylinder honeycomb-shaped, each cylinder centerline is installed with a cathode discharge needle, this structure can ensure that the electric field under the action of high-voltage static electricity to produce maximum average electric field strength. The cylinder is made of 0.5mm thickness 201 stainless steel, which is not easy to deform and easier to clean. The dedicated intelligent high-voltage electrostatic power supply has strong power and high energy utilization, and has the functions of constant current output control, arc-out protection, multiple discharge protection, high-voltage open-circuit protection, high-voltage short-circuit protection, power overload protection and transformer over-temperature protection. The unique structural design of electric field and insulation ceramic reduces the halo current and effectively improves the "coking" phenomenon of oil smoke; The device has cloud service management function, can be equipped with modules for online management. The series of products using stainless steel honeycomb electric field first-level treatment, suitable for import initial concentration of about 10mg/m3 medium and low concentration of soot, emission standards. Export concentration ≤ 2mg/m3, this series of products for non-methane total hydrocarbons, particulate matter, odor and other oil and smoke exhaust pollutants have a certain removal efficiency.
