Abstract

The utility model provides a cooking smoke purifier, which comprises a smoke tube communicated with a casing and a suction hood, a fan, a clean room, an air exhaust cover, and a high-pressure frequency changing power device. The inside of the casing is provided with a group of flow guiding rings and filtering nets; a group of high-pressure needle electrodes which are provided inside of a clean room and are connected with a high-pressure frequency-changing power device. The mixed smoke gas of cooking smoke peculiar smell inside of a clean room is processed via a degradation treatment and a cleaning treatment by making use of the high-pressure frequency-changing electronic technology and the theory of electrochemistry. The utility model has the advantages of reasonable design, simple structure, low manufacture cost, convenient mounting and use, convenient management and maintenance, and good cleaning treatment effect, and the utility model reaches the requirement of the smoke gas exhaust emission standard.

Description

Food and drink oil smoke peculiar smell clearing machine

Technical field:

The utility model relates to a kind of device that cooking fume waste gas is carried out purified treatment, belong to the environmental protection technical field of electricity, specifically a kind of food and drink oil smoke peculiar smell clearing machine is particularly suitable in hotel, dining room, spills in the catering industries such as building, hostel and install and use.

Background technology:

Along with the high speed development of Chinese Urbanization construction and tourist industry, effectively advanced hotel, dining room, spilt the fast development of food and restaurant service industries such as building and hostel.Though hotel, the dining room, spill the building and can provide table delicacies delicacy for people's tourist catering, promote the local economy prosperity, but in the hotel, the dining room, spill and cook the cooking in the kitchen in building when making, can produce a large amount of oil smoke inevitably, mixing is full of smoke is full of in the kitchen for steam and various flavouring gas peculiar smell etc., severe contamination kitchen environment not only, make the interior metope in kitchen, the surface area trapped fuel of kitchen tools articles for use and the tableware dirt of being bored with, the greasy dirt that becomes is difficult to clean, and according to surveying and determination, fill the air that mainly to contain composition in the mixing oil smoke smog that is full of in the kitchen be macromolecule lipid, number of chemical harmful substances such as hydro carbons are the No.1 killers of serious threat health of people.For improving the working environment in the kitchen, just present, generally to be the mode that adopts traditional installation smoke exhaust ventilator or ventilation fan with oil smoke peculiar smell waste gas directly be evacuated to outdoorly discharges sky, the pollution of oil smoke gas with foreign flavor has certain effect in kitchen to alleviating for this, but this directly with cooking fume peculiar smell mixed flue gas pump drainage to outdoor mode, not only can make dirty the outer surface of wall of building, the city look and feel in heavy damage city, and the macromolecule lipid that contains in the cooking fume, number of chemical harmful substances such as hydro carbons are understood the severe contamination air, have a strong impact on the PE health of community in urban areas.We can say, hotel, dining room, spill the important exhaust emission source that the building must be administered the environmental protection just of cooking fume peculiar smell mixed flue gas, the administrative department of municipal administration of the direct pump drainage of sky.

The utility model content:

The utility model be propose on the basis of existing technology a kind of reasonable in design, simple in structure, manufacturing cost is low, it is extremely convenient to install and use with management maintenance, utilize high-pressure frequency-conversion electronic technology and electrochemical principle to the degrade food and drink oil smoke peculiar smell clearing machine of purified treatment of cooking fume peculiar smell mixed flue gas, it is mainly by being communicated in casing, the smoke pipe of air-suction cover, blower fan, hood and high-pressure frequency-conversion supply unit constitute, it is characterized in that: one group of filter screen is installed in casing, between casing and hood, the clean room is installed, be connected in the high-pressure frequency-conversion supply unit by one group of high pressure needle electrode of insulating frame supporting arrangement in the clean room, it is work like this: by blower fan cooking fume peculiar smell mixed flue gas is pumped to casing from air-suction cover, send in the clean room with even distribution mode after the big oil dripping dirt in one group of strainer filtering absorption mixed flue gas, when the high-pressure frequency-conversion supply unit is switched on, in the clean room, form high voltage electric field by one group of high pressure needle electrode, the high pressure needle electrode carries out the macromolecule fat in the point discharge divergent bundle formation high voltagehigh frequency discharge current bombardment mixed flue gas, the chemical bond of hydro carbons chemical substance, macromolecule fat in the mixed flue gas, the hydro carbons chemical substance is degraded to the carbon of low molecule free state, hydrogen, oxygen element, the ozone that generates with airborne combination with oxygen is the smell substance oxidation in the mixed flue gas again, and discharging gets final product to sky by hood after thoroughly eliminating the oil smoke peculiar smell.

The utility model also has following technical characterictic:

Inwall at casing is equipped with one group of guide ring, and mixed flue gas enters the clean room through pod apertures, can prevent the attached wall adhesion effect of oil smoke motion, and it is smooth that mixed flue gas is moved in casing.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment:

The food and drink oil smoke peculiar smell clearing machine that the utility model proposes is implemented by following technical solution: it is mainly by being communicated in casing 7, the smoke pipe 6 of air-suction cover 2, blower fan 4, hood 17 and high-pressure frequency-conversion supply unit 14 constitute, at the top of hood 17 rain-proof cover 19 is installed, one group of guide ring 5 and one group of filter screen 9 are installed in casing 7, between casing 7 and hood 17, clean room 11 is installed, the power supply box 12 of device high-pressure frequency-conversion supply unit 14 is fixedly installed in the outer wall of clean room 11, be connected in high-pressure frequency-conversion supply unit 14 by one group of high pressure needle electrode 15 of insulating frame 16 supporting arrangements in clean room 11, it is work like this: start blower fan 4 the cooking fume peculiar smell mixed flue gas air inlet 1 from air-suction cover 2 as shown in arrow 3 is pumped to casing 7 through smoke pipe 6, pod apertures 8 water conservancy diversion through one group of guide ring 5 middle part, one group of filter screen of the warp let-off 9 filters impurity dirt and the big oil dripping dirt in the absorption mixed flue gas, send in the clean room 11 with even distribution mode again, when high-pressure frequency-conversion supply unit 14 is switched on by attaching plug 13, in clean room 11, form high voltage electric field 10 by one group of high pressure needle electrode 15, one group of high pressure needle electrode 15 carries out point discharge, divergent bundle forms the macromolecule fat in the high voltagehigh frequency discharge current bombardment mixed flue gas, the chemical bond of hydro carbons chemical substance, make the macromolecule fat in the mixed flue gas, the hydro carbons harmful substance is degraded to the carbon of low molecule free state, hydrogen, material elements such as oxygen, under electric field action, generate ozone with airborne oxygen, smell substance in the cooking fume is carried out strong oxidation, can thoroughly eliminate the oil smoke peculiar smell, the residual air after the degraded purified treatment is with nontoxic free of contamination water vapour, the material form of carbon dioxide tail gas is got final product by 18 pairs of empty dischargings of exhaust outlet of hood 17.
