Description
Technical field
The utility model relates to oil smoke processing technology field, refers to a kind of cooking fume remover especially.
Background technology
Along with the fast development of economy, improving constantly of living standards of the people, China's catering trade is developed rapidly, but oil smoke of catering industry discharge is not controlled effectively, oil smoke untreated is in a large number through smoke exhaust ventilator or ventilating fan is unordered is discharged in outside atmosphere environment, great harm is caused to surrounding environment, thus jeopardizes our life and health; And adhere on lampblack absorber and ventilating fan due to the material such as smog, flue dust, cause cleaning abnormal difficult, easily cause disaster hidden-trouble.For this reason, State Environmental Protection Administration has promulgated " oil smoke of catering industry discharge standard " (GB18483-2001) in 2000, industry of putting somebody on a diet unit must install cooking fume control equipment and reach the emission request of regulation.
The various catering industry such as restaurant, wineshop and residential households create a large amount of oil flue waste gas in the process of culinary art, processed food, and it is made up of oil gas, oil droplet and mist of oil.Its main source has three kinds: decomposed by the thermal oxide of grease and the contained lipid of food itself; In food there is chemical reaction in carbohydrate, protein etc.; Interactional secondary response thing etc. between the intermediate product of above-mentioned reaction or end product.Pollutants from cooking fume has particle and volatile gaseous two kinds of forms, and its chemical composition is aliphatic acid, alkane, alkene, aldehydes, ketone, alcohol, ester, aromatic compound and heterocyclic compound mainly.Wherein, polycyclic aromatic hydrocarbons (PAH) is one of material directly causing lung cancer, carcinoma of urinary bladder.It is reported, containing the organic matter of more than 75 kinds in oil flue waste gas, comprise alkane, aldoketones and derivative thereof.When the temperature of oil smoke reaches more than 300 DEG C, form a large amount of free radicals and MDA, and fat-soluble height, easily enter blood circulation, to body, there is lungs toxicity, immunotoxicity, carcinogenic mutagenicity, and the free radical of induced synthesis is in vivo one of pathologic basis of cancer.Some penetrating odor simultaneously produced in cooking food is discharged in the environment of surrounding with oil smoke, causes great impact to the respiratory system of human body, the organs of vision and health.Secondly oil smoke is a kind of aerosol, there is stronger adhesiveness, permeability, be often mixed into the toughening oil paste being difficult to remove with the silt in environment, dust etc. and be attached on the building of surrounding, be difficult to remove, not only affect visual experience, and easily cause fire.
We install mist extractor equipment to be transferred directly in air by oil smoke at present, although have certain alleviation to the air pollution in kitchen, can not remove the pollutant in oil smoke, bring serious pollution hidden trouble to air.
Recent domestic has had the technology of many improvement oil flue waste gas, its technological process is generally be purified by main reactor after flue gas is collected by oil-collecting petticoat pipe, be positioned at the air exhausting device non-stop run of oil smoke outlet, first for main oil smoke reactor provides power, second the flue gas purified is discharged rapidly.Equipment main in process is main reactor, and the reactor of different fume purifying mechanism is different.
According to the difference of fume purifying mechanism, the oil smoke processing technology adopted both at home and abroad at present mainly comprises the inertial collision method of purification, filters adsorption cleaning method, liquid scrubbing method, high-pressure electrostatic sedimentation, thermal oxide burning method, photodissociation oxidizing process, the chemical catalysis method of purification and biological treatment etc.But due to the particularity of oil flue waste gas composition, conventional purification method has respective limitation, as high in cost of investment, vapour lock is large, easily blocking, regular maintenance difficulty is large, efficiency is low, easy generation secondary pollution etc.
Equipment at present for kitchen fumes purification respectively has its pluses and minuses, and purification techniques haves much room for improvement.We are through the practice more than 2 years, on the basis absorbing external advanced technology for cooking fume control, in conjunction with the feature of self, have developed the oil smoke ecological purification system of environment-friendly type, have that equipment is simple, energy consumption is low, efficiency is high, investment and operating cost is few, do not produce secondary pollution, be easy to the advantages such as management.
Same category of device at present in this technical field is generally mechanical type, wet type or electrostatic merely; Mechanical type is that filtering material is blocked by soot particles very soon, and the system air draft of making is affected.Wet type is for be generally placed on outdoor, and winter easily freezes, and wants the mounting portion of multi-effluent pipe-line system in addition.Merely electrostatic for electrostatic installation be in petticoat pipe end, effect is not produced to flue oil-collecting, timing to clear up flue, otherwise just likely breaking out of fire, in oil flue waste gas, smoke particle viscosity is larger, easily be bonded on pole plate, impact to voltage electrostatic field, to the trapping of grit and purification efficiency, has maintenance cost after installation, also has equipment stream oil phenomenon, have noise, install complicated, power consumption is large.

Described active carbon strap assembly 5 adopts the V-type roller frame rolled; Total institute is known, the maximum advantage of active carbon is the material that can adsorb molecule, reach the object that purifies air, particularly important to PM2.5, but it also has its shortcoming, and that is exactly be easy to passivation after water breakthrough, loses suction-operated simultaneously, and water content own is just high in the oil smoke in kitchen, this structure of design utilizes the roller frame of V-shaped.1, increase and decrease active carbon cloth contact surface 1.5 times, 2, adopt roller to use active carbon strap, utilize the preheating of smoke pipe and the effect of air to be dried up by external active carbon cloth, recover that it is active, Reusability, solution active carbon is with changing problem frequently.
Wherein, described high-frequency electrostatic assembly 3 is by electrostatic attraction board, and the attaching parts such as sparking electrode, high pressure generator and installing plate form.As shown in Figure 3, when oil-soot mixture passes through, in electrion region, greasy dirt particle is decomposed, charing, and produces a large amount of anions simultaneously, make greasy dirt particle charge, and be adsorbed on adsorption plate at collecting region, under adsorption plate, slide into collecting region.
Wherein, described UV photodissociation assembly 4 is made up of 5 high frequency UV quartz burners.As Fig. 4, when oil smoke is by this region, under photolysis, most organic gas is broken down into carbon dioxide and water, and the oxygen simultaneously in decomposition gas forms active very strong ozone, carries out purified treatment by ozone to the smell in oil smoke.
Preferably, described screen pack 2 adopts grid to be that the netted stainless steel mesh sheet of 3*3 is made; The oarse-grained oil smoke a large amount of when oil smoke is by this device and screen pack 2 collide, and precipitate along screen pack 2, and simultaneously a part of smoke particle collision rift becomes short grained oil smoke material and enters in next casing 1.
Oil smoke enters cooking fume remover in through air inlet 8 from kitchen fume mist after collecting, first bulky grain oil droplet and some impurity because effect of inertia and screen pack 2 collide by adsorption filtration, oils particle concentration after outflow pretreatment section is reduced greatly, pretreatment section has the characteristic automatically drained simultaneously, do not block, and impurity can be trapped in pretreatment section, thus ensure that electric field normally works.Flue gas concentration after pretreatment unit is more balanced, therefore through out-of-date in certain high-tension electric field, clashed into by a large amount of electric charges of corona discharge in electric field, a large amount of elaioleucites in cooking fume are by highly ionized, decompose, carbonize, and produce a large amount of anions, make the elaioleucite that is suspended in cooking fume charged.Charged elaioleucite to dust collecting electrode motion, arrives pole plate and loses electric charge, be finally deposited on collecting plate under the driving of electric field force; After purification, the oil smoke of more than PM100 is all collected.
Under the effect of air-introduced machine, cooking fume mixed pollutants enters in UV casing 1, under the effect of UV photodissociation, major part organic gas, as the molecular chain structure of ammonia, trimethylamine, benzene,toluene,xylene, make organic or inorganic macromolecule malodorous compound strand, under high energy ultraviolet light beam irradiation, degraded is transformed into low molecular compound, as CO2, H2O etc.
The oxygen molecule simultaneously utilizing high energy high ozone UV ultraviolet beam to decompose in air produces free oxygen, i.e. active oxygen, because positron-electron that free oxygen is taken is uneven so need be combined with oxygen molecule, and then produces ozone.
UV+O2 → O-+O* (active oxygen) O+O2 → O3 (ozone),
Well-known Pre-Ozonation on Organic Matter has extremely strong oxidation, has to foul gas and other excitant peculiar smell the elimination effect got instant result.The active factors ozone (O3) be decomposed into by oxygen wherein, decomposes and taste removal the toxic substance in flue gas and peculiar smell.
Enter afterwards and be equipped with in the casing 1 of active carbon strap, activated charcoal solid also exists lack of equilibrium and unsaturated molecular attraction or valence bond power on the surface, therefore when this surface of solids contacts with gas, just gas molecule can be attracted, its dense coalescence is made to remain on the surface of solids, polluter thus adsorbed.
By above 4 grades of multi-level purified treatment, the clearance of oil smoke can be made to reach more than 98%.
The ion wind that the horizontal prickle that Particular craft makes produces, increases the horizontal migration velocity of soot particles, is conducive to moving to dust collector pole; Spaced anode, makes particulate produce coalescence effect, is conducive to process submicron order flue dust, improves the purification efficiency of product.
Several ultraviolet light device display is furnished with in photochemistry kitchen fumes odor eliminator, when entering photochemistry kitchen fumes odor eliminator containing poisonous and the high molecular flue gas of peculiar smell, these polymer substances are photodissociation fast under intense UV rays is irradiated, and molecular chain rupture, is decomposed into Small molecular group.Small molecular group after decomposition generates nontoxic small-molecule substance with the oxygen generation oxidation reaction in air under the light of CF and the catalysis of photocatalyst; Simultaneously, the oxygen of air capacity is also reacted into ozone under the catalysis of UV-irradiation, and ozone molecule has strong oxidizing property, can by Middle molecule gene oxidation after being decomposed in oil flue waste gas, generate the small-molecule substance that odorless is harmless, thus make the large high attenuation of peculiar smell or disappear completely.Catalyst converter display is made up of catalytic matrix and photocatalyst, photocatalyst fixing by catalytic matrix, when nanometer light catalyst ultramicron accepts Ultraviolet radiation, oxygen and the moisture of its adsorption are activated, produce active extremely strong hydroxyl radical free radical OH, hydroperoxyl free radical HO2, ultra-oxygen anion free radical O2 isoreactivity free radical, these living radicals and the ozone life-span extremely short, oxidation activity is extremely strong, successively there is oxidation reaction in ozone and these living radical double actions Small molecular group very fast after catalysis photodissociation, generate water (H2O), the small-molecule substances such as carbon dioxide (CO2), realization eliminates the unusual smell, mildew-resistant, scrubbing is self-cleaning, the function of purifying smoke.
Activated carbon non-woven strap relies on the pore structure adsorbed oil smoke particle of self uniqueness, and active carbon is a kind of outward appearance made primarily of carbonaceous material be black, internal pore structure is flourishing, specific area greatly, a class microcrystalline carbon materials of high adsorption capacity.Have micropore invisible in a large number in absorbent charcoal material, micropore in 1 gram of absorbent charcoal material, being launched that rear surface is long-pending can up to 800-1500 square metre, specific use higher.That is, in the activated carbon granule of a grain of rice size, the internal surface area of micropore may be equivalent to the size of a parlor area.These are highly developed just, the pore structure as human capillary vessel, make active carbon have excellent absorption property.Between molecule, the active force of absorption mutually is also named " Fan Dewa gravitation ".Although molecular motion velocities is by the impact of the reason such as temperature and material, it under microenvironment be all the time do not stop transport dynamic.Owing to having the active force attracted each other between molecule, after a molecule is entered into active carbon inner pore by the seizure of active carbon endoporus, owing to attracting each other between molecule, more molecule can be caused constantly to be attracted, until fill active carbon inner pore.
The utility model installs and uses requirement according to different, and module and clean unit adopt the design of split drawer type, have dismounting freedom, easy to clean, not fragile, change easy, service life is longer.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
