Description

Cooking fume remover

The present invention relates to the fume purifying apparatus that removes mist extractor that a kind of catering trade is used, specifically adopt air-flow power that oil smoke is washed the device that multistage purifications such as adding the atomization gas processing is realized deep purifying and discharging.

At present, the device that removes mist extractor of catering trade use mainly comprises three types, the water treatment mode; Absorption, filtering material mode; The high-pressure electrostatic mode.The water treatment mode comprises water curtain, water atomization or two kinds of principal modes of water filtration again and since water smoke or water filtration form with flue gas by washing after, the area of water oil contact increases, water strengthens the absorbability of mist of oil, thereby it is better to absorb the oil smoke effect.The water treatment mode has cost supports, simple in structure, is easy to affected maintenance, can remove some water-soluble pernicious gases, can realize that fiery cigarette and oil smoke handle simultaneously, fiery cigarette capable of blocking advantage such as scurry out.But there is the defective that is difficult to overcome in conventional water treatment mode, and the bad meeting of wastewater treatment causes secondary pollution, particularly the granule aerosol is removed efficient and supports, and water-oil separating is bad can a large amount of water smokes of ejection.

Absorption, filtering material mode help to adsorb the granule aerosol in the oil smoke, but along with adhering to of mist of oil is saturated, adsorption capacity can weaken gradually, must often change the regeneration sorbing material, operating cost is higher, and some sorbing materials can cause the chimney windage excessive be unfavorable for the smoke evacuation; Special design structure absorption, filtering material degreasing unit hydrous water treatment facility use, and can overcome the shortcoming of general sorbing material, but also have the shortcoming of part steam ejection.

Though it is strong that the high-pressure electrostatic mode has granule aerosol removal ability, can not cause the advantage of secondary pollution, but its cost, operating cost height are poor to the pernicious gas adsorption capacity, easy care does not use, and Insulation Problems is difficult for a series of defectives that are difficult to overcome such as solution.

The inventor comprehensively brings into play advantage of the prior art through studying for a long period of time and testing, and solves to have overcome the technical solution that defective proposes a kind of fairly perfect fume purifying.

The objective of the invention is to overcome the defective of prior art, provide a kind of and will wash the cooking fume remover that combines with adsorption treatment.

The object of the present invention is achieved like this, clarifier comprises ventilation blower, atomize the gas treatment tan, and the smoke absorption jar constitutes, it is characterized in that tourie absorbs ring by ring smoke, the end jar that fills absorption liquid constitutes, and the jet that absorbs the arrangement of ring base circle communicates with end jar, and jet comprises impact tube and disperser; Axial fan is connected with the tourie center by the tubulose atomize the gas treatment tan; Atomize the gas treatment tan is by central shaft, the block the fog wheel, the nylon bruss that distribute successively from bottom to top along central shaft, and the honeycomb fashion Cooking fume filter of the honeycomb screen of lower end and upper end constitutes.

Because what the present invention adopted in design is the technical scheme that washing combines with adsorption treatment, the series of advantages that has kept washing and adsorption treatment, as: can remove water-soluble pernicious gas, realize that fiery cigarette and oil smoke handle simultaneously, block fiery cigarette and scurry out, effectively adsorb granule aerosol in the oil smoke etc.Simultaneously,, avoided above two kinds of defectives that the conventional treatment mode is brought effectively, realized efficient purifying oil fume, and used and safeguard very simple and conveniently, ventilation blower has not been needed to do regular scouring safeguard with low cost by structural appropriate design.

Below in conjunction with the embodiment in the accompanying drawing technical scheme of the present invention is described further.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the B-B cutaway view of Fig. 1.

Fig. 4 is the C-C cutaway view of Fig. 3.

As shown in Figure 1, cooking fume remover of the present invention comprises, ventilation blower 3, and atomize the gas treatment tan 17, smoke absorption jar etc. partly constitute.When cooking fume remover is worked, the driven by motor blade rotation of axial fan 3 produces the outwards air-flow of discharging, air flue by inner sealing makes the air inlet 6 place's pressure declines on the smoke absorption ring 15 form vacuum, and the kitchen fume of exhaust fume collecting hood below relies on the vacuum state of ventilation blower import and is inhaled into tourie.

Tourie is by the smoke absorption ring 15 of annular, and the end jar 9 that fills absorption liquid constitutes.Jet 18 (as shown in Figure 3) in the bottom annular arrangement that absorbs ring 15.Jet comprises impact tube and disperser 13, and the oil smoke air communication is crossed on the liquid level that jet and disperser be sprinkling upon absorption liquid for 13 times and quick-boiled dark washing.Absorption liquid in the end jar is an akaline liquid, to the bulky grain aerosol material in the oil smoke and pernicious gas (acidity) have strong infiltration dissolving and in and performance, most mist of oil and peculiar smell dissolved absorption in the once washing process in the oil smoke.

Disperser 13 is many prismatics, because the condition of work of disperser is abominable, is in work under the high temperature for a long time, also has fiery cigarette burning sometimes, and the surface is easy to fouling, therefore adopts ceramic die casting, surface glazing.End jar 9 is convenient for working service, also is provided with water intaking valve 7, sewage draining exit 10, dipperstick 14 annexes such as grade.

Atomize the gas treatment tan 17 by tubulose between the top at tourie center and the ventilation blower links to each other, the tubulose atomize the gas treatment tan is by the central shaft 19 that is installed on the bearing spider assembly 5, the block the fog wheel 16, the nylon bruss 2 that distribute successively from bottom to top along central shaft 19, and honeycomb fashion Cooking fume filter 4 formations of the honeycomb screen 12 of lower end and upper end, 11 is the wind direction guide plate.

The atomization gas that absorption liquid and greasy dirt mix that rebounds out when the oil smoke air-flow pours absorption liquid liquid level mixed dissolution presents the unordered cloth that spreads out of " soap foam " shape bubble simultaneously on liquid level.These atomization gas are mingled with " soap foam " and are subjected to urgent continuation of ventilation blower import 6 pulls of vacuum to enter atomizing process tank 17 along the rising of tourie centre pipe.It is little that the honeycomb screen 12 of atomizing process tank 17 lower end import configurations is cut unordered turbulent flow " soap foam " isolation, and " little soap foam " and atomization gas are on the laminar flow to be inhaled.

The atomization gas of last suction, " little soap foam " passes block the fog wheel 16 and the nylon bruss 16 on the central shaft 19.Last inspiratory flow is along flow passage between the block the fog wheel blade face, and impeller is produced moment make it around central shaft 19 rotations, its the partly atomized gas of pressing close to blade profile of atomization gas that flows at blade passage is adsorbed by blade because of viscous and is condensed into water droplet, these water droplets are got rid of on tube wall because of the rotary centrifugal force effect of block the fog wheel, and sink to flowing back to end jar 9 along tube wall.Absorption and centrifugal force cleaning through block the fog wheel, remaining atomization gas is inhaled in the motion on continuing, adsorbed by centrifugal brush again, the atomization gas that is adsorbed in the centrifugal brush rolls up the globule through the viscous effect of nylon bruss 2, got rid of to tube wall by action of centrifugal force and sinks to flowing back to end jar 9.

In order further to handle atomization gas, block the fog wheel 16, nylon bruss 2 in the atomize the gas treatment tan 17 can multistagely dispose, in embodiments of the present invention, employing be on central shaft, to arrange the two-stage block the fog wheel from bottom to top respectively, one-level nylon bruss, the configuration of one-level block the fog wheel and nylon bruss again.Multistage configuration can multistage purification, but progression is provided with too much and also can influences performance of ventilating, and therefore what separation is set take into account two aspects.

Through multistage block the fog wheel and absorption of centrifugal brush and cleaning, remaining atomization gas is filtered through the honeycomb fashion Cooking fume filter that can regularly clean and change 4 of atomize the gas treatment tan 17 upper ends again.This cleaner utilizes the physics vortex principle to absorb remaining atomization gas and micro-flue gas, reaches further deep purifying effect.

The gas that passes cleaner 4 has been clean, does not contain the gas of water smoke, is discharged into the exterior space through ventilation blower.Because what the process ventilation blower was got rid of is the gas of deep purifying, ventilation blower is to work in the purified gas environment, does not therefore need regular scouring to safeguard.

In order to adapt to various environments for use, cooking fume remover of the present invention is furnished with conventional temperature control equipment 8 at end jar, and purpose is to freeze when avoiding in low temperature environment using, and what adopt in the present embodiment is that the PTC temp-controlling element is controlled as temperature.
