The soot pollution of the catering industry can not be underestimated. It not only seriously damaged the urban environment, but also greatly reduced the quality of life of the citizens. Nature based is based on the balance of the ecosystem and is balanced by the balance of the natural system. The intrinsic value of nature is more than a human tool. Environmental protection must follow the laws of nature.

不能把個人的利益凌駕于大自然之上，技術按照目前來說已經很成熟，但大多數人缺乏足夠的知識和經驗，導致各類劣質產品充斥，許多根本不具備起碼技術、設備粗制濫造。

Can't take personal interests above nature. In according to the current technology is already very mature, but most of them lack of professional knowledge and experience, leading to all kinds of inferior products flooding, many do not have at least crudely made technology and equipment.

慣性分離法：主要有金屬網罩、格柵等設備在廚房抽油煙機中廣泛采用。處理效果為40-50%左右。

Inertial separation method: mainly metal mesh cover, grille and other equipment, widely used in kitchen range hood. The treatment effect is about 40-50%.

靜電沉積法：主要設備采用雙區電沉積、沖洗雙區電除塵。處理效果為80%以上。

Electrostatic deposition: the main equipments are double zone electrodeposition and flush double zone electrostatic precipitation. The treatment effect is more than 80%.

液體洗滌法：采用的設備為工業各類濕式除塵器如篩板塔、沖擊式水膜除塵器等。處理效果為30-40%左右。

Liquid washing: the equipment used for industrial various types of wet dust collector, such as sieve plate tower, impact water film dust collector. The treatment effect is about 30-40%.

蜂窩沉積法：結構簡單，利用物理降溫原理，使油氣快速凝結，使油煙及水蒸汽能夠在腔內冷卻凝聚成為大顆粒的油珠并產生液化集油現象。處理效果為60-80%左右，阻力大，清洗工作量大，過濾水耗量也大。

Honeycomb deposition method: simple structure, the use of physical cooling principle, so that the rapid condensation of oil and gas, soot and water vapor can be cooled in the chamber, condensed into large particles of oil beads, and produce liquefied oil collection phenomenon. The treatment efficiency is about 60-80%, the resistance is large, the cleaning workload is large, and the consumption of filtration water is large.
