The water with washing liquid is pressurized by the water pump and sent to the smoke hood to spray into a fan shape. The oily gas coming from below the hood is decontaminated and purified when it contacts the fan shaped water surface, and the water flows back to the water tank after being separated by the gas-liquid separation fan. This is the basic working principle of the hookah hood. The hookah hood is equipped with a complete automatic control system for sewage discharge, water addition, detergent addition, circulation, etc., which is very convenient for operation.
