Abstract

The utility model relates to an oil smoke purifying device. A baffle plate, a vortex filter with a honeycomb type surface, an empty cavity which is respectively communicated with a filtering device on the top part and the vortex filter on the lower part are arranged in an upper sucking type smoke exhaust hood; a plasma generator arranged on the smoke exhaust hood is inserted into electrodes in the empty cavity and controlled by an impulsive discharge device and takes the action of pulse discharge to oil drops which are sucked in; the plasma generated by the electrodes enables the oil drops with small grain diameter to be mutually condensed so as to form the oil drops with bigger grain diameter and fall into the vortex filter under the action of self weight; sheet-shaped materials pressed with Y-shaped slots are mutually overlapped in a positive and negative alternation mode to form the vortex filter; the oil drops easily flow to oil collecting slots by being guided by the slots, and thereby, the purpose of collection is realized.

Description

A kind of fume purifier of fume

The utility model relates to purifier, particularly a kind of device of making purified treatment at catering industry discharging oil smoke.

The oil smoke discharge of urban restaurant trade and vehicle exhaust, industrial waste gas are that three of urban air pollution is originated greatly, contain harmful to health in a large number organic matters such as heterocycle, aromatic compound and aldehyde, ketone, hydro carbons, aliphatic acid and alcohol in the flue gas that edible oil commonly used produces in the catering industry after heating, above-mentioned treatment of organic matters of organic is adopted water spray process or Cottrell process usually, make it become oil droplet by said method, so that collect; But shortcoming is: the water spray process is because oil is immiscible with water, and is limited by spray particle diameter and time of contact, and its treatment effeciency and concentration of emission can't reach the discharge standard of country; Cottrell process needs the configuration high voltage distribution installation because of using direct-current discharge, and structure is complicated, expense is higher, and the oil-collecting of electrode own, and greasy dirt easily is attached on the electrode, the electrode failure that accomplishes, and efficient is lower.

The purpose of this utility model provides a kind of electrode discharge that utilizes, and can better collect oil droplet and lower-cost fume purifier of fume.

The utility model includes the updraft type enclosure, baffle plate and eddy current cleaner are housed on the air entry of enclosure, the throat of enclosure is provided with a cavity, this cavity is connected with the filter on lower vortex cleaner and top respectively, be fixed on plasma generator on the enclosure by the electrode in the pulse discharge means control cavity, make electrode in cavity, do pulsed discharge.

More than in the said eddy current cleaner the flaky material mutual superposition and form " people " font groove.

Adopt technique scheme, its electrode is interior and discharge in the pulsed discharge mode because of being positioned over cavity, need not to dispose high-pressure installation, and lower cost, security performance are higher; The nonequilibrium plasma of Pulsed Discharge, its city, ionization district is wideer than DC corona, and contains active stronger free group and strong oxidizer O in the plasma ₃, and a large amount of opposite polarity ion, gaseous state harmful components in the oxidation oil smoke effectively, impel the less oil droplet of particle diameter to be condensed into the bigger oil droplet of particle diameter, fall into the cleaner of cavity bottom or, reach the purpose of collecting oil droplet by follow-up filter capture in the deadweight effect; The eddy current cleaner is arranged to cellular, and the flaky material in the cleaner forms tortuous runner with " people " font groove, can filter the bigger oil droplet of particle diameter, to reduce the processing load of plasma generator to greatest extent, improves service efficiency.

Following structure accompanying drawing is described in detail the utility model:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the sectional view of the utility model cleaner (3);

Fig. 3 is the shape schematic diagram that constitutes the flaky material (9) of eddy current cleaner

As shown in Figure 1: updraft type enclosure 1 hangs on kitchen range top top, be fixed with baffle plate 2 and eddy current cleaner 3 on the air entry of enclosure 1, the throat of enclosure 1 is provided with a cavity 8, this cavity 8 is connected with eddy current cleaner 3, filter 7 respectively, throat position at enclosure 1 also is equipped with plasma generator 5, generator 5 is controlled the electrode 4 that joins on it by pulse discharge means 6, make electrode 4 do pulsed discharge in cavity 8, the fixing filter 7 in oil extraction cover 1 top can be collected the oil droplet of the particle diameter minimum of discharging in the cavity.

Shown in Fig. 2,3: the surface of eddy current cleaner 3 is cellular, flaky material (aluminium flake) 9 of " people " font groove 10 forms with positive and negative alternate mutual superposition by punching press, the turning angle of this groove 10 is an an angle of 90 degrees, thereby on cleaner 3, form tortuous runner, be convenient to make the bigger oil droplet of particle diameter to be reached separation, and finally collect in the oil trap because of effect of inertia dams

Its course of work is: the oil smoke of discharging is collected by enclosure 1, by baffle plate 2 and eddy current cleaner 3, enter cavity 8, pulse discharge means 6 control electrodes 4 in the plasma generator 5 are done pulsed discharge, electrode 4 produces plasma, make that the less oil droplet of particle diameter condenses mutually in the oil smoke, form the bigger oil droplet of particle diameter and fall into eddy current cleaner 3, and the littler oil droplet of particle diameter is inhaled into the filter 7 of cavity 8 tops and carries out entering atmosphere after filtration, purification is handled, its purified gas meets the standard-required of national GWPB-2000, and the bigger oil droplet of the particle diameter that falls into eddy current cleaner 3, then groove 10 water conservancy diversion that form by flaky material 9 stacks are gone in the oil trap of enclosure 1 bottom.
