and the oil collecting cup is arranged right below the oil collecting net.
The method comprises the following two working modes:
the oil fume extraction mode is as follows: starting an oil smoke fan in the new oil smoke purification fan, starting a first vertical lifting unit, lowering an oil smoke collecting hood to a position 65-80cm above a cooking bench through the first vertical lifting unit, and exhausting indoor return air and oil smoke to the outside through an oil collecting net, an oil smoke hose and an oil smoke purification channel in the new oil smoke purification fan in sequence; the oil smoke purifies passageway includes indoor return air inlet, the dynamic filtration net dish that sets gradually along oil smoke circulation direction, little electrostatic module, ultraviolet lamp, photocatalyst, adsorption module, oil smoke fan and air exit. The oil collecting net intercepts large-particle grease, the dynamic filter screen disc intercepts more than 90% of fine-particle grease, and the micro-static module intercepts more than 99% of grease smaller than 1 micron and fine particles in oil smoke.
An oil collecting groove is arranged below the dynamic filter screen disc, and intercepted grease and particles can be collected through an oil collecting port in the dynamic filter screen disc; the micro-static module is a washable module.
A method for treating Volatile Organic Compounds (VOCs) in lampblack comprises the following steps: the ultraviolet lamp, the photocatalyst and the adsorption module carry out high-efficiency purification treatment on the ultraviolet lamp and the photocatalyst. By intercepting oil and fat, intercepting fine particles and purifying Volatile Organic Compounds (VOCs), the accumulation of indoor oil stains and the pollution to the outdoor environment are avoided.
The specific process and parameters of the oil fume purification are as follows: the effective treatment of particulate matters and VOCs is carried out through an oil collecting net, a dynamic net disc, a micro-static module, ultraviolet rays, a photocatalyst and an adsorption module. The scientific principle and the process are as follows:
firstly, an oil collecting net, a dynamic net disk and a micro-static module carry out gradient filtration and interception on particles with different particle sizes in the oil fume.
Firstly, the oil collecting net mainly realizes effective filtration and interception of oil fume particles with the particle size of more than 10 mu m, and the intercepted oil is collected by an oil collecting cup at the central lower end of the oil collecting net;
and then the dynamic mesh disc effectively intercepts the oil smoke particles with the particle size of 1-10 mu m, so that more than 90% of the fine oil smoke particles are intercepted, the work load of the micro-static module is effectively reduced, and the cleaning frequency of the micro-static module is reduced. The design parameters of the dynamic net disc comprise the number of spokes, the diameter of the spokes, the rotating speed of the motor and the oil smoke flow rate, the interception effect and the silencing requirement are comprehensively considered, the net disc rotates at a high speed of 1300 plus 2100 revolutions per minute to form mechanical shielding, effective interception and noise reduction of oil smoke particles are realized, and the test results of the purification efficiency and the set parameters are shown in the following table.
| Serial number | Rotating speed (r/min) | Spoke diameter (mm) | Number of spokes (strip) | Oil smoke flow rate (m/s) | Purification efficiency (%) |
| 1 | 1200 | 0.5 | 180 | 2.43 | 74.07 |
| 2 | 1300 | 0.5 | 180 | 2.43 | 80.25 |
| 3 | 1400 | 0.5 | 180 | 2.43 | 86.42 |
| 4 | 1500 | 0.5 | 180 | 2.43 | 92.59 |
| 5 | 1600 | 0.5 | 180 | 2.43 | 98.77 |
| 6 | 1700 | 0.5 | 160 | 2.92 | 77.63 |
| 7 | 1800 | 0.5 | 160 | 2.92 | 82.19 |
| 8 | 1900 | 0.5 | 160 | 2.92 | 86.76 |
| 9 | 2000 | 0.5 | 160 | 2.92 | 91.32 |
| 10 | 2100 | 0.5 | 160 | 2.92 | 95.89 |
And finally, the micro-static module realizes the high-efficiency interception of the superfine oil smoke particles with the particle size smaller than 1 mu m, so that more than 99 percent of the fine oil smoke particles are intercepted. The interception process of the micro-static module comprises charging, coagulation and collection interception of ultrafine particles. The high-voltage electrostatic field in the module has obvious coagulation effect on dust, irregular lapping and adhesion occur among particles, and the apparent particle size of dust particles is increased from 50-100nm to 5-15 mu m, so that the dust particles can be better trapped and intercepted.
Oil collecting net, developments net dish, little electrostatic module filter the high-efficient gradient of oil smoke granule, have ensured ultraviolet ray etc., photocatalyst and adsorption module's effective work for ultraviolet lamp's actual emission effect reaches the radiant intensity of design, and the catalyst on the photocatalyst is not become invalid by oil smoke granule adhesion, also lets adsorption module can not adsorb the oil smoke granule and influence the effect and the too early absorption saturation that adsorb VOCs, increases use cost.
And the ultraviolet rays, the photocatalyst and the adsorption module sequentially decompose and adsorb the VOCs.
First, VOCs are photolyzed and catalytically purified by ultraviolet light and a photocatalyst, wherein photons of a certain wavelength (sufficient energy) emitted by the ultraviolet light can break chemical bonds and possibly produce strongly oxidizing species, titanium dioxide, etc., excited by the photocatalystElectrons and holes generated by the compound semiconductor participate in oxidation-reduction reaction, and the electrons and the holes are coupled to effectively convert VOCs into H2O and CO2。
Wherein the ultraviolet rays are emitted from 2-4 low-pressure mercury discharge tubes with wavelength of 254nm or 185nm, and the photon energy is 472KJ/mol and 647KJ/mol respectively. Preferably a 185nm wavelength low pressure mercury discharge vessel, to break the molecular bonds to the VOCs in most lampblack as shown in the table below.
| Molecular bond | Binding energy (kJ/mol) | Molecular bond | Binding energy (kJ/mol) |
| C-N | 305 | O-H | 464 |
| C-O | 326 | C-F | 485 |
| C-C | 332 | O＝O | 498 |
| S-H | 339 | C＝C | 611 |
| N-H | 389 | C＝O(CO2) | 828(803) |
| C-H | 413 | C≡C | 837 |
| H-H | 436 | C≡N | 891 |
The VOCs are then adsorbed using an adsorbate, such as activated carbon, in the adsorption module. The adsorption process of the activated carbon comprises physical adsorption and chemical adsorption. The active carbon is a porous carbon-containing substance and has a highly developed pore structure, the huge surface area provided by the porous structure of the active carbon can be fully contacted with VOCs, and the physical adsorption effect is achieved due to the attraction effect between molecules; the activated carbon not only contains carbon, but also contains a small amount of oxygen-containing functional groups on the surface of the activated carbon, such as carboxyl, hydroxyl, phenols, lactones, quinones, ethers and the like, and can chemically react with the adsorbed VOCs to achieve the effect of chemical adsorption. High humidity in oil fume, H2O and VOCs have a competitive adsorption relationship, and modified hydrophobic activated carbon is preferred, so that the binding force between VOCs molecules and the surface of the activated carbon is improved. The following table shows three kinds of adsorption of benzene and formaldehyde in organic silane reagent modified hydrophobic active carbon K-I and K-II and unmodified active carbon at different relative humidityTime of penetration on the additive. The modified K-I hydrophobic activated carbon is preferably selected, so that the adsorption capacity and the binding force of the modified K-I hydrophobic activated carbon to VOCs in kitchen oil smoke with higher humidity are improved, and the adsorption efficiency of the VOCs in the oil smoke is improved.
