The purification of Jin Jieli smoke-free bbq car mainly adopts a combination of physical filtration and high-voltage electrostatic discharge. Firstly, the fan sucks in the oil fumes generated by grilling into the car, and through the front filter or interceptor, intercepts most of the large particles such as oil and grease particles in the smoke. Subsequently, the smoke enters the high-voltage electrostatic field. In a high-voltage electric field, gas is ionized to produce a large number of charged ions, which attach to tiny oil mist particles and charge them. The charged particles are adsorbed onto the electrode plate under the action of electric field force, and finally flow into the oil collection tray under the action of gravity. Meanwhile, the ozone generated by the electric field can also decompose harmful gases and remove odors. After this series of purification processes, the clean air ultimately meets the emission standards, and the oil fume removal rate can reach over 99%
