Description
Technical field
The present invention relates to food and drink and household cooker hood technology for cooking fume control field, be specifically related to a kind of smoke exhaust ventilator.
Background technology
Current fume purifying mainly contains following three kinds:
First, common Cooker hood, the method utilizes oil smoke naturally to adsorb oil smoke in flue gas through sheet metal, provides power to make oil smoke enter in petticoat pipe by the induced draft fans installed on pipeline, and grease can be made to remain in a large number metal surface that oil smoke passes through forms dirt to the method, and purification efficiency is extremely low, can not discharge standard be reached, be easy to breaking out of fire in actual use, cause personnel's property loss, need frequent pipe blow-through, cost is also higher.
Second, water smoke degraded Cooker hood, the method installs atomising head inside petticoat pipe, pump is as hydraulic atomized, suck oil smoke by the blower fan be arranged on exhaust duct to mix with fog, the method being oil water mixture backflow by isolation fan removes oil smoke, because the contact area of atomized water and oil smoke is very little, fully cannot absorb oil smoke, therefore after using for a long time, can make in pipeline, still have a large amount of grease to need cleaning, discharge not up to standard, also easily breaking out of fire, needs frequent pipe blow-through cost higher.
3rd, static fume adsorbs, the method makes smoke particle charged by electrion, oil smoke is by electric field substrate adsorption, time in the early stage, the method oil smoke adsorption efficiency is very high, because oil smoke has very strong viscosity and larger resistivity, so can stick on electrode and substrate, after use one end time, electric-field intensity reduces, adsorption capacity weakens to such an extent as to cannot adsorb oil smoke, due to the charged heating of oil smoke, so very easily make the oil smoke solidification being adsorbed on bottom, be unfavorable for cleaning, easily bring new pollutant such as, the ozone that high electrion produces and nitrogen oxide, contaminated air.

As shown in the figure, wherein corresponding Reference numeral name is called:
1 tank, 2 discharge outlet, 3 gaps, 4 ultrasonic oscillators, 5 water inlets, 6 casing of cooker hoods, 7 guidance panels, 8 blower fans, 9 filter screens, 10 spray headers, 11 sputtering mouth sprays.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further elaborated.
A kind of smoke exhaust ventilator as shown in Figure 1, it comprises casing of cooker hood 6, and described casing of cooker hood 6 lower end is pump orifice, and upper end is exhaust opening, in the position of described pump orifice, tank 1 is installed, described tank 1 one end is provided with discharge outlet 2, the other end is provided with water inlet 5, several ultrasonic oscillators 4 are installed in described tank 1, several ultrasonic oscillators 4 set gradually along the direction of discharge outlet 2 to water inlet 5 in tank 1, in the position of described exhaust opening, blower fan 8 is installed, described blower fan 8 one end is air outlet, the other end is air inlet, described air outlet is communicated with exhaust opening by smoke discharging pipe, in the position of described air inlet, spray header 10 is installed, described spray header 10 is connected with water pump by inlet channel, and this water pump is arranged in tank 1, several sputtering mouth sprays 11 are offered below described spray header 10, filter screen 9 is provided with above described spray header 10.
The present embodiment, by arranging ultrasonic oscillator 4, water in tank 1 is atomized, the drop diameter after atomization is made to remain between 0.05mm-0.2mm, thus ensure that the water droplet after atomization is to the suction-operated of oil smoke, by arranging spray header 10, to atomization after water droplet and the complex compound of oil smoke wash away, make it discharge smoke exhaust ventilator, avoid the pollution again to air.
In order to the complex compound being atomized rear water droplet and oil smoke remains in certain region, the preferred technical scheme of the present embodiment is, spray header 10 both sides are separately installed with dividing plate, and spray header 10 is by dividing plate and casing of cooker hood 6, by spray header 10 both sides, dividing plate is installed, just a region for being washed away by the oil smoke with water complexing is formed like this between spray header 10 and dividing plate, due to the negative pressure that blower fan 8 produces, simultaneously in the barrier effect of dividing plate, so just making can only in above-mentioned zone with the oil smoke of water complexing.
In order to the drop diameter after being atomized remains between 0.05mm-0.2mm, the preferred technical scheme of the present embodiment is, the ultrasonic frequency of excusing from death ripple oscillator 4 is that (preferred, ultrasonic frequency is 2.0MHz to more than 2.0MHz, when ultrasonic frequency is 2.0MHz, just can make to make water fogging).
In order to the complex compound reducing the water after atomization and oil smoke is inhaled in blower fan 8, the preferred technical scheme of the present embodiment is, filter screen 9 adopts stainless steel steel wire criss-cross weave to form, and the hole of described filter screen 9 is 50 molybdenums, and the hole of filter screen 9 is set to 50 molybdenums, when water smoke rises to filter screen 9 base, due to the hydrophily of filter screen, water is easy to stick on filter screen 9, thus promotes the backflow of water, reduces water smoke and is sucked into blower fan 8.
For the ease of the discharge more than moisture in tank 1, the preferred technical scheme of the present embodiment is also be provided with gap 3 in tank 1, and the upper end of described gap 3 flushes with the upper edge of tank 1.
In order to improve the service life of smoke exhaust ventilator, the preferred technical scheme of the present embodiment is that casing of cooker hood 6 adopts stainless-steel sheet to make.
According to one embodiment of present invention, smoke exhaust ventilator also comprises the guidance panel 7 be arranged on casing of cooker hood 6.
Operation principle of the present invention is as follows:
First blower fan 8 works and produces wind-force, and make air produce negative pressure, the oil smoke produced below smoke exhaust ventilator is sucked smoke exhaust ventilator, then the ultrasonic oscillator 4 by being placed in tank 1 produces the water of excusing from death ripple atomization tank 1, water is atomized into water smoke that diameter is about 0.1mm, surface area due to solid mass is fixing, although the volume of solid does not change substantially after being pulverized by solids, but the total surface area of solid particulate matter is far longer than original solid mass, so be equally also such principle as the water of fluid, water smoke after atomization adds the surface area of water, and be suspended in above the water surface, at this moment the oil smoke entering smoke exhaust ventilator fully will mix with the water be atomized above the water surface, in mixed process, the temperature of oil smoke can be reduced, granule simultaneously in oil smoke and water complexing, due to the structure of hydrone, water belongs to polar molecule, the molecule of edible oil is polar molecule equally, so can complexing be produced, finally, water after atomization and the complex compound of oil smoke are under the effect of blower fan 8, continue to rise between spray header 11 and dividing plate and just form a region for being washed away by the oil smoke with water complexing, due to the negative pressure that blower fan 8 produces, the barrier effect of dividing plate simultaneously, so just making can only in above-mentioned zone with the oil smoke of water complexing, in this region, the larger water droplet of diameter is sprayed by sputtering mouth spray 11, the complex compound of the water after atomization and oil smoke is cleaned, and make this complex compound enter in tank 1, discharged by discharge outlet 2, simultaneously in order to the complex compound reducing the water after atomization and oil smoke is inhaled in blower fan 8, filter screen 9 is also provided with above spray header 10.
The present invention can more efficient purifying oil fume, and decreasing pollution, through the test in one period of cycle, obtain fume purifying efficiency and on average can reach 93.0%, minimum purifying rate is not less than 89.6%.Oil smoke discharge is the highest is no more than 0.95mg/m
