Description

The device of hypergravity coupled low temperature plasma technology purifying oil fume

Technical field

The utility model fume purifier of fume, refers in particular to a kind of utilization hypergravity and non-thermal plasma trap purifying oil fume Device.

Background technology

Kitchen ventilation Environment Design, in residential architecture and public building, is important part.Kitchen is generally divided into Catering trade kitchen, external title commercial kitchen, Commercial Kitchen) and house kitchen (Residential Kitchen). Kitchen ventilation Environment Design, is important part in residential architecture and public building.

Due to the eating habit of distinct Chinese characteristics, the pernicious gas distributed during causing the Chinese way of cooking and particulate matter are compared with the world There is larger difference in west nationality, cooks Thermal plume, oil smoke of generation etc. more very in its kitchen.At present due to cooking generation in kitchen Thermal plume (ThermalPlumes), the unreasonable Design of ventilation such as oil smoke (Cooking Oil Fumes, COF) generates one and is Row problem of environmental pollution.The environmental pollution produced in kitchen is polluted not only for kitchen itself, is also embodied in surrounding environment Pollution.As Mr. Cai Guohan of one of gas-cooker GB draftsman represents：" in all kitchen guarding's environment, the kitchen of China Environment is most special ".

One research report of Britain shows, cooks, health is made on the kitchen range top that ventilating system is poor, burning efficiency is extremely low Into infringement, equivalent to two bag cigarettes are inhaled daily, such case causes 1,600,000 people dead in the whole world every year.The World Health Organization exists This problem is mentioned in the report of 2002 first, and report is classified as room air pollution on the ring of the maximum that developing country faces One of border hygienic issues.

Air Pollution in Kitchen, the burning harmful exhaust, useless that produce of the part from fuel (natural gas, liquefied gas etc.) Heat, oil smoke, mist of oil, steam and peculiar smell that another part is produced from heat foods gastronomical process, and heat radiation and noise are dirty Dye etc..The most important sources of PM2.5 that non-smoking is produced in developed country's building are exactly to be cooked with gas.Cooking fume is Edible oil and food volatile materials at high temperature produced by thermal cracking, containing substantial amounts of CO2, SO2, CO, NO, inhalable powder The strong carcinogen such as dirt and aldehydes, ketone, hydrocarbon, aliphatic acid, aromatic compound, heterocyclic compound, these materials body is had compared with Big harm.One of main component therein is methacrylaldehyde, has strong impulse to nose, eye, throat mucous membrane, can cause rhinitis, The respiratory diseases such as sphagitis, tracheitis.Suck this oil smoke for a long time, also result in asthma exacerbation, increase the machine for suffering from lung cancer Meeting.Cooking fume contains multiple toxic chemicals, and there is lungs toxicity, immunotoxicity, genetoxic and potential to body Carcinogenicity etc., becomes the potential hazard factor for affecting Restaurant practitioner and home cooking personnel healthy.

These promote people to proceed by pollutant in culinary art test and in-site measurement house and catering trade kitchen to distribute, The characteristic of research gas cooking emanation.How the dirt of pollutant diffusion, particularly respiratory region is efficiently controlled using local ventilation Dye thing concentration is the pressing issues for awaiting at present solving.Mould is controlled to the air pollution characteristic and local ventilation in catering trade kitchen The research of formula has theoretical and realistic meaning.

GB18483-2001《Cooking fume discharge standard》It is applied to existing catering trade unit, the food of discharge oil smoke to add The catering trade kitchen of work order position and non-profit-making internal institution staff canteen etc. all kinds of (except residential households oil smoke discharges).Which specifies Each corresponding heating power of benchmark kitchen range is 1.67x108J/h, and corresponding hood cooktop projected area is 1.1m2, per The exhaust air rate of individual benchmark kitchen range is 2000m3/h.

1.1 heat flow of table and the apolegamy table of minimum ventilation rate

In cooking process, not only distribute pernicious gas, while also give out substantial amounts of heat, so design exhaust air rate when Wait, it should which thermic load is taken into account.In design, petticoat pipe is more slightly larger than thermal source, the fluctuation shadow for preventing crossflow from producing Ring, frying pan mouth thermal source diameter dimension is often held 150～200mm of expansion.Fume exhaust cover belongs to low umbellate form cover.

Regulation of the China now for existing enclosure exhaust air rate, is all belonging to basic, and standard specify only lower limit, It is not specified by the upper limit.Mislead it is believed that enclosure air quantity bigger better.The conference excessively of air quantity brings the increasing of energy consumption and noise Plus.On the premise of the oil smoke arresting efficiency of enclosure is ensured, air quantity should be the smaller the better.

Because all cooking apparatus situation used at the same time is considerably less in kitchen, the thermal discharge of kitchen utensils will be multiplied by One reduction factor, referred to as concurrent signatures.Under normal circumstances, the size of concurrent signatures is 0.5-0.8, it means that The cooking apparatus of 50%-80% can all be used at any time.

The style of the existing enclosure of China is entirely different with the enclosure form in the U.S. or Europe.In order to avoid grease is in row Petticoat pipe glued on top is simultaneously fallen in pot under gravity.The design angle of the front side board of umbrella shape enclosure is about 30 °.Therefore Grease can be slipped to the channel of oil extraction along the front side panel of enclosure, and finally flow in catchment cup.The gear oil of enclosure Plate and side plate above together constitute the volume of a triangle, and the rectangle enclosure in this volume ratio U.S. or Europe will Little.

The reason for kitchen indoor thermal environment difference, is caused due to irrational air vent mode and air current composition.The heat of human body The uncomfortable cooling for being likely due to a certain privileged site of body or heating cause.Here it is going out in typical catering trade kitchen Existing so-called localized heat is uncomfortable.Its modal reason is too high vertical temperature-difference between blowing feeling, and head and ankle. By the analysis and evaluation air vent mode to test parameter and air current composition.Three evaluation indexes can be used:The vertical air temperature difference (VATD), blowing feeling and contaminant removal efficiency (CRE):

In hybrid ventilation, cold wind is generally by being sent with higher speed installed in the air diffuser of ceiling. This must produce a high momentum air-spray at high speed and air-supply is mixed with indoor air efficient.This air current composition mode The reason for being not necessarily optimal diet industry kitchen has two:

1. the high velocity air that air diffuser is sent can bring the air flow in unwanted kitchen or horizontal blowing, from And cause enclosure to be difficult to catch the Thermal plume that cooking apparatus is produced above.

2. the heat that multiple thermals source are distributed in kitchen can be caused to mix with kitchen indoor air flow.

However, having such misunderstanding in Chinese most designer and engineer, that is, think：In the hot ring in catering trade kitchen Border difference is only relevant with enclosure.If the efficiency high of enclosure, all it is identical regardless of the air current composition mode using type 's.They do not recognize negative effect of the air current composition to enclosure performance.

Additionally, all there is serious " overflowing side " phenomenon in general kitchen.This aspect is due to when cooking apparatus is in the kitchen range top End when being cooked, required exhaust air rate phase when together cooking with all cooking apparatus of the whole kitchen range top of the exhaust air rate needed for which With.On the other hand, the culinary art situation relative to Chinese style kitchen heavy loads is also illustrated that, the arresting efficiency of enclosure is too low.? In design, the exhaust air rate of enclosure is more to be estimated using rough face wind speed method, so as to have ignored the reality of culinary cuisine utensil The thermal discharge on border.In the system for so calculating gained, and though below cover be quick-fried heavy loads situation, or steamer Such slight load condition, the air quantity of enclosure are just as.External research is thought, before Chinese style enclosure The volume that the triangular-section of side plate composition result in enclosure is less, can reduce the arresting efficiency of enclosure.

Another phenomenon is that the change of relative humidity is always contrary with the variation tendency of temperature after firing.Show one Enclosure can not effectively catch and accommodate the pollutant of kitchen appliance generation, then the humidity and temperature in kitchen will not be simultaneously Increase.The reason for producing this phenomenon requires further study.However, this is likely due to Chinese tradition culinary art style, quick-fried Fry and fried, cause.Different from boiling and steaming the substantial amounts of vapor of generation, quick-fried and fried culinary art style can produce substantial amounts of Smog and particle, so humidity can be reduced and temperature rising in catering trade culinary cuisine environment.The temperature of non-cooking point on the kitchen range top Degree and the measuring point value exceeded just by the cooking apparatus of gas concentration lwevel.It will thus be seen that existing enclosure is preventing heat Amount and air pollutants are queried in the efficiency of the propagation in whole kitchen.
