Description
Technical field
The present invention relates to a kind of commercial kitchen lampblack purifying system, cooking a meal with combustion gas cauldron in especially a kind of commercial kitchen
The smoke exhaust ventilator exhausting duct and exhausting duct mounting bracket of stove.
Background technology
Kitchen is the element of house, is the main place that people carry out cooking activity.Due to various civilian combustions
Material burning, cooking fume and house refuse etc. make kitchen turn into " severely afflicated area " of house, and it is dirty that kitchen also turns into local-style dwelling houses room air
One of important sources of dye.Kitchen exhaust gas is most important dusty gas in kitchen, and it includes two kinds：First, fuel combustion process
The waste gas of release, second, food and grease carry out material caused by a series of physical chemical change at high temperature.Two kinds of materials
Spread in spatial mixing and rapidly, endanger the physical and mental health of people.
Most important composition is alkane and alkene in cooking fume, next to that organic acid, aldehyde compound and polycyclic aromatic hydrocarbon.
Although aliphatic hydrocarbon is not carcinogen, hendecane, dodecane, octadecane etc. are important rush cancer materials；Phenols, polycyoalkane
Also there is tumor promotion；Aldehydes has mutagens.
Oil smoke seriously pollutes kitchen environment while cooker physical and mental health is injured, and smoke exhaust ventilator can fire cooking stove
Caused waste gas is taken away in the waste gas and cooking process of burning.After fume exhaust fan blower starts, negative pressure is formed about at exhaust outlet,
Waste gas flows to air entry from surrounding, forms suction airflow and confluxes.When air suction area is smaller, " point sink " air-flow can be considered.Inhale
The streamline of air current flow outside gas port is the RADIAL centered on gas outlet, and isovelocity surface is using gas outlet as the centre of sphere, spherical point
Portion.But more pump drainages that oil smoke is directly carried out using smoke exhaust ventilator in currently available technology, it is harmful in oil smoke without considering
Pollution of the composition to air, and cooked a meal more using one or more is large-scale with gas big kitchen range, oil smoke in current commercial kitchen
It is easy to be immersed on smoke exhaust ventilator, does not allow very much disposable, it is necessary to exclusively carry out dismounting cleaning.
In addition, the exhausting duct of the smoke exhaust ventilator in commercial kitchen in currently available technology is directly installed on using flexible pipe more
On smoke exhaust ventilator, although this mode can utilize the flexibility characteristics of flexible pipe arbitrarily to bend, the service life of flexible pipe is beaten greatly
Discount, cause occur phenomena such as hose fracture in use, in turn result in oil smoke leakage, had a strong impact on the body of people
Health and environment.
The content of the invention
According to studying for many years, the creative structure to the exhausting duct of smoke exhaust ventilator in commercial kitchen is made to be changed the present invention
Enter, for this in view of the shortcomings of the prior art, the present invention provides a kind of commercial kitchen cleaning system, and it is mainly pumped using filtering type
Cigarette machine exhausting duct.
