Description
Technical field
The invention belongs to kitchen fume absorbent field, and in particular to a kind of kitchen oil fume purifying chaotropic agent and its preparation side
Method.
Background technology
Domestic restaurant unit can be produced in cooking process contains a large amount of poisonous and harmful substances in a large amount of oil smoke, oil smoke, oil
Cigarette not only to the cold air and condense into greasy dirt be attached to smoke extractor surface either building surface can influence environmental sanitation, oil smoke
Immune system, breathing system can be also caused after mist of oil is sucked by human body with being formed after the condensation of the small molecular collision such as the moisture in air
System, reproductive system are damaged, or even trigger gene mutation and cancer.
At present, common oil smoke processing method has following several：The first is filtration method, and this method operation principle is profit
The pollutant of bulky grain is retained with mesh.Filtering for oil smoke needs mesh gap smaller, but is also therefore easier
Block, it is necessary to be replaced and cleaned often.Filtration method goes the removal efficiency of fume eliminating to reach 80%~92%, and pressure drop is big, invests small, but
Because the protective effect time of individual layer is short, it is necessary to regularly replace filtrate, therefore operating cost is larger.It is easy to maintenance, reload conveniently,
But it is big to take up space, and can only typically be placed in outdoor.Generally filter plant is stable, but using cumbersome, it is necessary to fixed
Phase changes filtrate.If not considering that floor space can be preferentially from the happy row purifier of filtering for some food and beverage enterprises.
Second is liquid scrubbing method, and the principle of this method is pollutant is occurred the transfer of phase by gas-liquid contact.
Using the hydrophobicity of oil smoke droplet, the detergent containing compositions such as surfactant, alkali, detergent can be added in slurry
Sprayed, fully contacted with oil smoke with spray pattern by nozzle after uniformly being mixed with running water, then above oil smoke absorption chamber
Impeller gets rid of mist of oil, aqueous vapor etc., so that it may greatly improve the efficiency of fume purifying.Liquid scrubbing method is common oil smoke processing skill
Art, goes fume eliminating efficiency high, and peculiar smell generation is less while fume eliminating is removed, while also having cleaning function to equipment.But liquid
Body washing method needs the cooperation of a variety of devices such as water pump, tank, nozzle, and the discharge of waste liquid has secondary pollution to environment
Problem.
The third is thermal oxide burning method, this method operation principle be using the oxidation reaction promoted with heat, from

Treatment process [J] Liaoning urban and rural environment science and technology, 2001,01:45-48).
4th kind is wet method fume purifying method, and the operation principle of this method is under a certain pressure, to allow water and cooking fume
Fully contact, thus makes the mist of oil particle in oil smoke form the oil-in-water fog particles wrapped up by water smoke, that is, oil-in-water
Particle is the aerosol of dispersed phase, so that the purification of oil smoke is converted into demisting purification, this reduces cooking fume purification
Difficulty.Water smoke that oil-in-water fog particles are sprayed by equipment nozzle, moisture film, and by inertia, retention, diffusion with water droplet
Flow into water tank.After water oil mixture reaches saturation, the oil reservoir on surface can be scraped off recycling.This purification method
Purification efficiency is up to 80% or so, and pressure drop is smaller, stable, it is easy to maintenance clean, takes up space smaller.But in the process of running
Equipment needs power consumption, add water (detergent), so expense is larger, and the problem of have secondary pollution, is less suitable for that (Zhang Zhi is used for a long time
State building room aerosol contaminants discharges and its research [D] the Wuhan University Of Technologies administered, 2003).Utilize oil smoke droplet
Hydrophobicity, the detergent containing compositions such as surfactant, alkali can be added in slurry, so that it may greatly improve oil smoke net
The efficiency of change.This method cost of equipment is low, and operation maintenance amount is small, and floor space is small, economy is high.But because lack suitable oil smoke
Absorbent, and lack the technology of waste liquid after-treatment and develop limited.
Therefore, a kind of fume eliminating efficiency high is researched and developed, kitchen oil fume purifying chaotropic agent cost-effective and environmentally friendly is extremely important.
