Description
Technical field
The present invention relates to oil smoke discharge processing technology field, and in particular to one kind is using overweight field magnetic force line cutting separation oil
The method and device of mist purified treatment oil smoke, for CNC numerically controlled lathes, surface grinding machine, spray testing room, electric spark
The oil smoke in the place such as processing, numerical control machining center, hotel, restaurant, wineshop, dining room and school, office, factory
Zero-emission purified treatment.
Background technology
With the development of China's tertiary industry and the quickening of urbanization process, diet service trade institute in urban economy development
The proportion accounted for is increasing.The rapid development of catering trade, flourishing urban economy, urban development but is simultaneously promoted
Also serious infringement is brought to environment.Undressed oil smoke is exhausted directly to outdoor, and skin face and air are made
Into serious pollution.At present in Surveying of Urban Air Pollution Sources, cooking fume pollution and CNC numerically controlled lathes, surface grinding machine,
Spray testing room, electrical discharge machining, industrial pollution caused by numerical control machining center and automobile exhaust pollution turn into master in the lump
The pollution sources wanted.Fume pollution not only influences urban public environment health, also there is very big harm to health.Diet
Oil smoke contains many poisonous and harmful elements, and different food products can produce different volatile materials at high temperature, wherein containing
Many mutagenesis and carcinogenicity material.Multiring aromatic hydrocarbon (PAH) in oil smoke component etc. is carcinogenic substance, and China's tradition is cooked
Process contaminant of preparing food is held in both hands and is placed with strong carcinogen and 5~7 kinds of venomous injurants.It is reported that the same kitchen fume of lung cancer morbidity rate
Pollute closely related, and some domestic regional female lung cancer incidences of disease are much higher than male, and the cooking fume of higher concentration
With lungs toxicity, cooking fume causes lung capacity to be decreased obviously, and can influence the cellular immunity of body, macrophage
Function, GVT etc. are so that the immunologic function of body declines；Also there is gene can be caused to dash forward in cooking fume
The cytogenetic toxicity material of the different biological effect such as change, DNA damage, chromosome damage, not only there is heredity poison
Property, and there is potential carcinogenicity.
It is reported that there is family kitchen more than 300,000,000 in China, there is the food and beverage enterprise more than 200 ten thousand of scale, every year because culinary art is produced
Raw oil smoke is to PM2.5 contribution rates more than 20%.Harm of the cooking fume to people is quite big, and cooking fume contains a variety of
Toxic chemicals, there is genetoxic, immunotoxicity, lungs toxicity and potential carcinogenicity to body.
The normal life of city dweller of oil smoke discharge own severe jamming, causes the strong dissatisfaction of people, according to relevant money
Material statistics, the complaint that domestic many big city residents pollute to cooking fume have accounted for sum is complained in environmental protection 40%.
Therefore, country attaches great importance to administering food and restaurant service industry kitchen other cooking-fume discharging gas, has progressively issued corresponding laws and regulations pair
Oil smoke discharge is limited.2 months nineteen ninety-fives State Environmental Protection Administration, State Administration for Industry ＆ Commerce issue expect《On strengthening drinking
Eat the notice of entertainment service enterprise Environmental Management》And 1996 it is issued by the State Council《People's Republic of China's air is dirty
Contaminate anti-therapy》36th article is waited regulation：The operator of city food service enterprise must take measures to prevent and treat cooking fume
Pollution to neighbouring resident's living environment；It must be provided with collecting oil smoke, the device of peculiar smell, eliminate cooking fume to air
Pollution.On July 1st, 2000, implemented through State Environmental Protection Administration's approval《(the examination of cooking fume discharge standard
OK)》, it is specified that oil smoke discharge standard limited value (highest allows the volume mass of discharge be 2.mg/m3) and monitoring is analyzed
Method, the environmental management of the sector is set tentatively to have gone on regulation and standardization track.On September 1st, 2000, state
Family implements revised《Air Pollution Prevention Law》In, increase " the operator of city diet service trade, it is necessary to adopt newly
Take measure, preventing and treating oil smoke pollutes to the living environment of neighbouring resident " clause and specify that the law of blowdown owner
Responsibility, being truly realized cooking fume prevention and cure of pollution, there are laws to abide by, ensures that law breakers be prosecuted.
Because the research of current domestic kitchen oil fume purifying is also in the starting stage, people endanger understanding to oil smoke and are not enough to
And its processing method is lacked and paid attention to, food and beverage enterprise of China and family kitchen all do not reach much to the efficiency of fume purifying
It is required that therefore, analyzing the pollution situation of oil smoke, oil smoke processing new technology and method is proposed, it is very urgent.
At present, domestic and international typical purification method and equipment mainly include following several：
1st, inertial separation method
The principle of inertial separation method is by forcing to make cooking fume air motion direction that strong turnover occur, making cooking fume
In particulate matter reach depositional plane under effect of inertia and spun off from gas.Capital equipment is industrial usual
Inertial separation demisting facility, mainly there are metal weaving guard, grid etc., these equipment are at present in family expenses conserving kitchen oil smoke pumping
It is widely used in machine, using also more universal in some old-fashioned catering trades.Its major advantage is that equipment is simple, pressure drop compared with
Small (being usually 50-200Pa)；Drawback is low to the particle clearance of small particle, and total removal rate is also relatively low, generally
For 50%-70%, and due in oil smoke particulate matter viscosity it is very big, clean and maintenance workload is larger, limit its
Popularization and application in the purification of catering trade cooking fume, and the requirement enforced the law with China's urban environmental protection is more and more tight, mesh
Application of the preceding this method in catering trade cooking fume purifying and recovering system is more and more restricted.
2nd, electrostatic deposition
The operation principle of electrostatic deposition is that cooking fume is introduced into high voltage electric field, and particulate matter is charged in cooking fume, in electric field
To dust polar motion under power effect, and deposit and removed from oil smoke.Capital equipment is heavy to industrial two-region electricity
Product, the equipment rinsed after electric dust collector with double zone remodeling.It is mainly characterized by that facility compact, floor space be small, purification efficiency

The advantages of be change cleaning solution property, the SO that can be gone simultaneously in fume eliminating2、CO2、NOxDeng waste gas, particulate matter
Purification efficiency it is also higher；But limited by wet scrubber performance, it is less efficient to the particle purifying of submicron order；
Scrub raffinate not yet can be solved preferably, and the current practice is also easy to produce secondary dirt for scrub raffinate directly is discharged into sewer
Dye problem：In addition, the consumption of cleaning solution often results in increasing for operating cost, these problems all limit to a certain extent
The popularization and application of liquid scrubbing method are made.The method is further improved in terms of the modification of scrub raffinate and reprocessing.
4th, fabric filtration method
The principle of fabric filtration method is oil smoke when passing through fiber mat in clarifier, and particulate matter is due to spreading, retaining, being used to
Property collision etc. effect and be removed.The fabric of generally use is the high polymer composite of oil absorbency.This method
The advantages of be purification efficiency height, generally up to more than 90%, stable and reliable operation, but due to fiber mat trapping particle
Thing viscosity is higher, removes by common flow by gravity or extruding and is all difficult to realize, and pressure drop is larger, as glass fibre is filtered
Bed pressure drop is up to 1500Pa；These problems make the application of fabric filtration method by a definite limitation.
5th, thermal oxide burning method
The principle of thermal oxide burning method be using pick into oxidation reaction, by the harmful poisonous composition conversion in cooking fume
Into safe condition, in order that all emission burnings are complete, make the thermal efficiency optimal, while keep NO againxDischarge
Minimum limitation, used technology are complicated.Stirling Asian company succeeds in developing patented multistage combustion system

Expect the situation of gas composition, the fast food being relatively more suitable for based on frying and industry.The cooking method of my catering trade
Varied, combustion method is generally less adapted to the national conditions in China, and its is applicable to be limited in scope.
6th, auto purification catalyst method
The principle of the catalyst cleaning method of auto purification is to use the various catalyst with self-purification function, in gastronomical process
Oil drops are converted into by CO by catalytic oxidation combustion on sub- cook temperature2And water vapour, so as to eliminate pollution and stink.
Auto purification catalyst is substantially made up of catalyst heat resistance binding agent and mud (porous), is sintered in open type kitchen range
On inwall.At present, such catalyst that Japan has developed is widely used to cook in exhaust-gas treatment, principal mode
Have：By means of Y-MnO of low melting point Li bonding glass2, molecular sieve and ferrite and the metal oxygen bonded by organic bond
Compound.These catalyst also have hot dipping permeability far infrared transmission work(in addition to the characteristics of being vented with purification
Can, the function of improving cooking speed and dish taste color is can reach, is made particularly suitable for small and medium restaurant and home cooking
With.The shortcomings that auto purification catalyst method, which is that kitchen range are integrated with catalyst, make it that the replacing of catalyst and regeneration are difficult,
Cost is higher, may be only available for small-sized cooking oil fume purification.
7th, catalyzing, oxidizing and purifying method
Catalytic purification method refers to organic component in the cooking fume by discharge in the presence of catalyst, under certain temperature
Complete oxidation is the CO of environmental sound2And water.At present, catalyzing, oxidizing and purifying method processing cooking fume there is no reality at home
Border is applied, research work also rare report：Once someone was developed at electric furnace heating wire heat using proofing Pd, plating Pt method
Manage dimethylbenzene/butyl acetate and obtain certain effect, but not yet directly fume purifying system is given in application.
8th, complex method
Complex method refers to the combination of above several method, reaches and mutually learns from other's strong points to offset one's weaknesses, increase purification efficiency, at reduction
Manage cost.The purification method such as combined using liquid absorption with metal mesh filter, it is preferable to achieve relative single method
Effect, but structure is relative complex, and cost is also higher.
In above-mentioned several method, mechanical means is to the clearance of aerosol up to 80%~90%：Charcoal absorption gas
The efficiency of colloidal sol is 40%~70%, and the purification to gas has obvious effect；Cyclone type separates the effect of aerosol
It is poor；All mechanical means are very poor to the removal capacity of gaseous contaminant.Electrostatic methods are to aerosol state pollutant
Clearance is 80%~90%, it is impossible to removes gaseous contaminant.Wet treatment method Water spray (tower, box) effect
For 40%~75%, hydro-vent is 85%~92% except reason effect, removal of more satin part washing absorption methods to oil smoke
Rate is up to 96%.Wet treatment method has stronger catharsis to gaseous contaminant, to SO2Clearance up to 64
%.Complex method can take into account the advantages of different disposal method, can improve the clean-up effect of oil smoke, but complicated, make
With there is certain limitation.
Analyze and can be seen that more than, by kitchen institute oil extraction mist contains gas-liquid-solid tri-state material simultaneously, no matter that side
The substance viscosity that method traps is all very big, so when electrostatic precipitation equipment and traditional filtering equipment all have useful effect
Between not long situation, and there is the problems such as cleaning pole plate is difficult, and operating cost is high in electrostatic method；Inertial separation equipment clean
Efficiency is low；Washing facility processing oil smoke efficiency high can also remove smell, but need the auxiliary equipments such as water pump, tank, lead
Cause operating cost high, plus the mist of oil and micronic dust purified in off-odor and the secondary dirt of waste liquid caused by the deposition of pond
Dye problem, using it also has certain limitation.Complex method although improving purification efficiency to a certain extent,
But still the defects of high operating cost and secondary pollution be present, it is impossible to fundamentally solve the problems, such as oil smoke processing.
At present, Chinese cooking fume control equipment industry is in the rapid primary stage for developing progressively maturation.From environment protection treating
For technical standpoint, if disregarding cost, current technology, which can accomplish to administer oil flue waste gas completely, arrives indoor discharge
Environmental friendly principle is inherently run counter in standard air, saying of still " disregarding cost ", meanwhile, allow food and drink in need
