OIL FUME PURIFICATION APPARATUS
The present invention relates to the technical field of oil fume treatment, and particularly relates to an oil fume purifica- tion apparatus.
Cooking fume pollutants substantially refer to volatile cil and organic substances generated in high-temperature food cooking and processing, and a solid-liquid-gas mixture produced through thermal oxidation and pyrolysis, main components of which are hy- drocarbons, lipids, alcohols, and aromatic and heterocyclic com- pounds. An odor produced by cooking fume seriously influences com- fort and physical sense of residents, and also causes respiratory diseases of the residents and even damages human health. Moreover, after the cooking fume is cooled, it can condense into fine parti- cles so as to be discharged into an environment, which will influ- ence quality of an atmospheric environment.
Purification methods for cooking fume mainly include mechani- cal purification, electrostatic deposition, washing absorption, filtration absorption, etc. These treatment methods mainly focus on purification of oil droplets and particles in oil fume, and has a limited removal rate of volatile organic compounds (VOCs)--a source of an odor in the cooking fume. Resident disturbance due to the odor can still occur.
At present, odor removal of the cooking fume mainly uses a
VOCs-based purification technology, which includes ultraviolet (UV) photolysis and activated carbon adsorption. However, market application of UV photooxidation is limited by its low efficiency, high cost and complicated operation and maintenance, which is only in a pilot application stage. Activated carbon has an obvious ef- fect of removing an odor, but is short in service life and high in operation and maintenance cost, which make it impossible to popu- larize the activated carbon in a large area. At present, room-
temperature catalytic oxidation is considered to be a suitable pu- rification method for volatile organic compounds in oil fume gas.
Therefore, it is of great significance to develop an oil fume pu- rification apparatus having an odor removal function.
An objective of the present invention is to provide an oil fume purification apparatus, so as to solve problems in the prior art and effectively remove odor in oil fume.
To achieve the above objective, the present invention pro- vides the following solution:
The present invention provides an oil fume purification appa- ratus. The apparatus includes a housing, at least one oil fume filter, and at least one odor catalytic oxidizer. One end of the housing is provided with an oil fume inlet, and the other end of the housing is provided with an oil fume outlet. The oil fume fil- ter and the odor catalytic oxidizer are both fixedly arranged in the housing, and the oil fume filter is capable of filtering oil droplets and particles in oil fume. The odor catalytic oxidizer is arranged between the oil fume filter and the oil fume outlet, and the odor catalytic oxidizer is capable of catalytically oxidizing volatile organic compounds (VOCs).
Preferably, the number of the oil fume filter is one. The number of the odor catalytic oxidizers is three. The oil fume fil- ter and each of the odor catalytic oxidizers are arranged in par- allel and side by side.
Preferably, the odor catalytic oxidizer includes a holder and several catalyst-loaded molecular-sieve odor catalytic oxidation modules. Each of the catalyst-loaded molecular-sieve odor catalyt- ic oxidation modules is fixedly arranged on the holder. The holder is fixedly arranged in the housing.
Preferably, the oil fume filter and the odor catalytic oxi- dizer are both fixedly provided with handles. The handles are pulled such that the oil fume filter or the odor catalytic oxidiz- er is pulled out from an interior of the housing.
Preferably, the oil fume purification apparatus further in- cludes heaters. The number of the heaters is equal to that of the odor catalytic oxidizers. Each of the heaters is fixedly arranged on each of the odor catalytic oxidizers. Each of the heaters is capable of heating each of the odor catalytic oxidizers.
Preferably, the oil fume purification apparatus further in- cludes a controller. The controller is fixedly arranged outside the housing. The controller is connected to each of the heaters in a communicating manner. The controller controls each of the heat- ers to work.

All other examples ob- tained by those of ordinary skill in the art based on the examples of the present invention without creative efforts shall fall with- in the protection scope of the present invention.
An objective of the present invention is to provide an oil fume purification apparatus, so as to solve problems in the prior art and effectively remove odor in oil fume.
To make the above objective, features, and advantages of the present invention clearer and more comprehensible, the present in- vention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in FIGs. 1-2, the present invention provides an oil fume purification apparatus. The apparatus includes a housing 2, at least one oil fume filter 3, and at least one odor catalytic oxidizer 9. One end of the housing 2 is provided with an oil fume inlet 1, and the other end of the housing is provided with an oil fume outlet 7. The oil fume filter 3 and the odor catalytic oxi- dizer 9 are both fixedly arranged in the housing 2, and the oil fume filter 3 is capable of filtering oil droplets and particles in oil fume. The odor catalytic oxidizer 2 is arranged between the oil fume filter 3 and the oil fume outlet 7, and the odor catalyt- ic oxidizer 9 is capable of catalytically oxidizing volatile or- ganic compounds (VOCs).
According to the oil fume purification apparatus provided by the present invention, the oil fume filter 3 is arranged to filter the oil droplets and the particles in the oil fume, and the odor catalytic oxidizer 9 is arranged to catalytically oxidize the
VOCs, such that the odor of the oil fume is purified, and further the odor in the oil fume can be effectively removed.
As a preferred embodiment of the example, the oil fume outlet 7 is externally provided with and connected to an induced draft fan, and the oil fume is sucked by means of the induced draft fan, such that the oil fume can efficiently pass through the housing 2.
As a preferred embodiment of the example, the number of the oil fume filter 3 is one, the number of the odor catalytic oxidiz-
ers 9 is three, and the oil fume filter 3 and each of the odor catalytic oxidizers 9 are arranged in parallel and side by side.
Herein, it should be noted that the number of the oil fume filters 3 mounted may be determined according to a filtering requirement 5 of the oil droplets and the particles, and the number of the odor catalytic oxidizers 9 mounted may be determined according to a odor purification requirement.
As a preferred embodiment of the example, the oil fume filter 3 is a high-efficiency nano filter.
Further, the odor catalytic oxidizer 9 includes a holder 5 and several catalyst-loaded molecular-sieve odor catalytic oxida- tion modules 4, each of the catalyst-loaded molecular-sieve odor catalytic oxidation modules 4 is fixedly arranged on the holder 5, and the holder 5 is fixedly arranged in the housing 2. A catalyst may be a noble metal nano-catalyst or a non-noble metal nano- catalyst that is applied to a molecular sieve. Herein, it should be noted that a filling quantity of the catalyst-loaded molecular- sieve odor catalytic oxidation module 4 may be determined accord- ing to the odor purification requirement.
As a preferred embodiment of the example, the oil fume filter 3 and the odor catalytic oxidizer 9 are both fixedly provided with handles 8, and the handles 8 are pulled such that the oil fume filter 3 or the odor catalytic oxidizer 9 is pulled out from an interior of the housing 2, which facilitates subsequent cleaning and maintenance.

It is ensured that the catalyst does not need to be re- placed for a long time and is still in a state of high conversion efficiency, which can ensure that the apparatus may implement ef- ficient purification of the odor of the oil fume for a long time,
effectively prolong the service life, and reduce operation and maintenance cost. In the example, a heating regeneration tempera- ture of the catalyst is 100°C-200°C, and regeneration time is 10 min-60 min.
