Frequently with the inertial collision method of purification, Filtration Adsorption method, electrostatic method, liquid scrubbing in prior art The isolated system of the methods such as method or combination unit treatment and purification kitchen fume.Existing process described briefly below The purification method of kitchen fume, device:

1, Filtration Adsorption formula fume purifying method

Filtration Adsorption formula cooking fume remover is that hydrocarbon containing fluid first passes around the metallic grid of some with resistance Cut bulky grain pollutant, then during by filtering material (cloth), by filtering material to smoke particle Interception, absorption, molecular separating force etc. act on, and make smoke particle be retained down, the cleaning after purification Gas enters air by pipeline.The purification efficiency of the type equipment is with filtering material pore size, suction Depending on attached performances etc., can reach more than 90%, but purification efficiency is the highest, its resistance is the biggest, filters and inhales Attached formula smoke gas purification equipment can use organic composite material fabric or felt, inorganic filter material (to hate Water perlite, haydite, coke etc. are used singly or in combination), filtering material can be with flow of flue gas Direction vertical direction disposes, and after filtering material absorption is saturated, high temperature incineration processes.Its main feature: One is that when just filling, adsorption filtration is effective, and purification efficiency is typically at 80%-92%.Two is to need often to change Absorption and filtering material, along with the attachment of mist of oil, absorbability can gradually weaken, and adsorbing material can be led Cause chimney windage excessive, be unfavorable for smoke evacuation, it is necessary to often change or regenerative adsorption material.Three is to take up an area Area is big, it is contemplated that filter efficiency and filter area, typically constitutes from ground area bigger.Four is that resistance is big, Consuming more electric power, filtration pressure drop is up to 1000Pa-1500Pa, and Filtration Adsorption formula cooking fume control equipment is all Need the electronic air exhausting device of supporting installation, be used for oil smoke of catering industry and process, make Filtration cleaning equipment Application is limited to.It is not suitable for that smoke density is relatively low, discharge erratic resident's fume purifying.

2, the electrostatic oil fume method of purification

Electrostatic oil fume deaner utilizes high voltage electric field principle, forms Electric Field Distribution, makes in flue gas bigger Oil mist particle, greasy dirt granule be captured due to mechanical collision, detention on homogenizing plate, oil or fat particles Move to the positive/negative plate of electric field under the electric field force and airflow function of absorption electric field and be collected on pole plate And under the effect of self gravitation, flow to draw-off tray, thus soot particles and sticky dust are carried out effect and catches Collection, discharges through oil drain passage, it is achieved oil smoke separates with air.This device volume is little lightweight, Just strong to little particulate aerosol removal ability during dress, purification efficiency is generally up to more than 85%, and pressure drop is less. Shortcoming is that cost is of a relatively high, and operating cost is higher, poor to harmful gas absorbability, during target phase Between, after pole plate is adhered to by mist of oil, it is not easily cleaned.

3, liquid scrubbing method

Liquid scrubbing method is to be contacted with absorbing liquid by special distribution device in gas-fluid by cooking fume, general Grain thing is from gas phase removal to liquid phase.Generally use spray, moisture film and the adsorption tower being connected with gas skirt Or depurator, but to use suitable absorbent and can not only use water and liquid detergent.

4, composite oil smoke cleaning equipment

Combined type equipment is to be primarily present particulate matter and volatile organic matter (VOCs) two kinds according to oil smoke State, processes respectively by the two.Kitchen fume through liquid absorptive unit, water smoke drainage screen, etc. from After the process of daughter unit, catalyst unit etc., the particulate matter such as mist of oil, white carbon black can be removed well, Also the gaseous contaminants such as volatile organic matter can be processed；Compared with tradition fume purifying technique, each unit Independent combined-type structure, clean and maintenance is convenient.

Above-mentioned existing fume purifying technique and equipment, mainly for the improvement of oil smoke of catering industry, have and control Reason exhausted air quantity is big, concentrate control emission, run time collection and neutralize the advantage that removal efficiency is high, simultaneously this A little techniques that purify have the shortcoming and defect that equipment installation cost is high, power consumption is high, operating cost is high, this A little shortcomings are not problems for the oil smoke processing of catering trade, but exist for money for resident's oil smoke processing The predicament that gold is difficult to raise, cannot be properly functioning.

Therefore, the unpowered purifier of gas particles thing that the application proposes, collection external environment natural wind, The multiple low values such as the outer row pressure power of stack effect, air heat power, frictional static power and resident's lampblack absorber move Power is comprehensively converted into the rotary motion of non-power consumption, by the rotation of the absorption filter element of built-in lightweight Motion, improving in flue while ventilation situation, enhances absorption mass transfer effect, selects at material On take full advantage of the superpower of the oil absorption material such as spray fusing polypropylene fibre or spray fusing superfine polypropylene fiber Absorption affinity.Residential kitchen oil smoke discharge has that installing space is little, the time is irregular, concentration of emission is low Feature, requires sensitivity to abatement equipment installation cost and operating cost, the gas particles thing of the application without Dynamic purifier is on the premise of low equipment cost, low operating cost, it is thus achieved that preferably oil smoke etc. The adsorption efficiency of gas particles thing, purification efficiency, be to solve residential kitchen fume purifying and administer optimal Scheme.

It is last it is noted that various embodiments above is only in order to illustrate the technical solution of the utility model, It is not intended to limit；Although this utility model being described in detail with reference to foregoing embodiments, It will be understood by those within the art that: it still can be to the skill described in foregoing embodiments Art scheme is modified, or the most some or all of technical characteristic is carried out equivalent；And this A little amendments or replacement, do not make the essence of appropriate technical solution depart from this utility model each embodiment skill The scope of art scheme.
