厨房排油烟系统系统的组成一个现代的排油烟系统主要包括:排烟罩、管道系统和风机排烟罩
The system of kitchen fume exhausting system consists of a modern exhaust system including exhaust hood, piping system and fan hood.
排烟罩用来收集从烹饪中散发出来的物质,这些物质来自食物和热处理过程,包含固态、液态、气态。几乎所有的排烟罩都是用不锈钢做的,其中油烟过滤器、分离器实际上都是火灾防范装置。今天我们用的最多的过滤器包括滤网、滤水器、干式过滤器三种。过滤器能够收集细微油污颗粒及蒸汽,但容易固体结构,使这些过滤器的弱点。新的滤网式过滤器通过增大接触面积,使其更具有吸收效果。过滤器需要一种过滤介质来收集油污。大部分过滤器都有不锈钢或者铝制成。
Smoke hood is used to collect substances emitted from cooking, which are derived from food and heat treatment processes, including solid, liquid and gaseous states. Almost all exhaust hood is made of stainless steel, and the lampblack filter and separator are actually fire prevention devices. The filters we use most today include three filters, water filters and dry filters. The filter can collect fine oil particles and steam, but it is easy to solid structure, making these filter weaknesses. The new filter can make the filter more effective by increasing the contact area. Filters require a filter medium to collect oil contamination. Most of the filters are made of stainless steel or aluminum.
油污及其危害
Oil pollution and its harm
当蒸汽、油脂、固体污染物通过排烟罩、管道、风机时,都会沉积在这些组件表面,久而久之就形成油污。根据烹调的类型和使用量,排油烟系统很短时间内就会沉积大量油污,一年就能达到几百公斤。
When steam, grease and solid pollutants are passed through smoke hood, pipe and fan, they will deposit on the surface of these components and form oil pollution over time. According to the type and quantity of cooking, the system will deposit a large amount of oil in a short time, and can reach hundreds of kilograms a year.

火灾危险
fire risk
每年在美国发生大约5000起餐厅火灾,损失高到8千万美元。这类火灾通常发生在烹调区域,然后通过排油烟系统迅速蔓延至房顶。油污燃烧最高可达1400度。
There are about 5000 restaurant fires in the United States each year, which cost up to $80 million. Such fires usually occur in cooking areas, and then spread quickly through the smoke exhaust system to the roof. Oil pollution can burn up to up to 1400 degrees.
环境健康隐患
Environmental health hazard
排油烟系统内油污的不断沉积,不但产生肮脏的气味,更容易滋生细菌,成为环境健康的危害。加大能耗,减少使用寿命,排油烟系统内的油污沉积增大了空气流通阻力,从而需要加大风机负荷,以保证正常工作。同时也缩短了设备使用寿命。
The continuous deposition of oil in the fume exhausting system not only produces dirty smell, but also tends to breed bacteria and become a hazard to environmental health. To increase the energy consumption and reduce the service life, the oil pollution in the exhaust system will increase the air flow resistance, so the load of the fan is needed to ensure the normal work. At the same time, the service life of the equipment is also shortened.
清洗的方法:
Cleaning methods:
在排油烟系统中,一些部分是方便拆卸、可触及的,如排烟罩、过滤器、风机。通常利用热压(>120巴)配合专用化学洗涤剂(pH>14)就能够清洗这些组件。而另一些不易触及、不可拆卸的,如垂直、竖直的管道,就需要专门的设备及方法。
In the lampblack system, some parts are easily dismantled and touchable, such as smoke hood, filter and fan. Usually, hot pressing (>120 bar) and special chemical detergent (pH>14) can be used to clean these components. Others, which are difficult to reach and cannot be dismantled, such as vertical and vertical pipes, require specialized equipment and methods.
