这是济南厨房排烟常用的一种排油烟罩，罩体水平投影面为长方形的，横截面似半边的伞形烟罩。长度根据灶具的数量和摆放长度决定，高度为550 mm，宽度一般在1250 mm，前沿带送风装置的总宽为1500 mm左右。罩体内一侧以60°的斜度装有迷宫式过滤油网，有一定的油烟过滤能力，经常在一般餐厅的厨房中使用。

This is a kind of lampblack hood commonly used for smoke exhaust in Jinan kitchens. The horizontal projection surface of the hood is rectangular, and the cross section is like an umbrella shaped hood with half sides.

将配有洗涤液的水经水泵加压后送到烟罩内喷洒成扇形，从罩体下方上来的油污气体在与扇形水面接触中被去污净化，而水经气液分离扇分离后流回水箱。这就是运水烟罩的基本工作原理。运水烟罩有排污、加水、加洗涤液、循环等整套的自动控制系统，操作使用很方便。经此烟罩净化后的气体除油率可达到90%左右基本不再污染管道，由于水雾的隔离作用，这种烟罩还有一定的防火功能。

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. The oil removal rate of the gas purified by the smoke hood can reach about 90%, and basically no longer pollute the pipeline. Due to the isolation effect of water mist, the smoke hood also has a certain fire protection function.
