The specific embodiment
Below in conjunction with accompanying drawing explanation and specific embodiments, the utility model is further illustrated.
The fume purifying based on carried catalyst that the utility model provides is processed integrated kitchen range, it is a kind of bottom discharge integrated oven of catalyst purified treatment oil smoke, its structure as shown in Figure 1 and Figure 2, comprise that side-suction type range hood 1, the kitchen range top 2, annular fume pipeline 3, device for catalytic treatment 4, temperature control equipment 5 and discharge duct 12 form, wherein: the air inlet of fume pipeline 3 is connected with side-suction type range hood 1, the exhaust outlet of annular fume pipeline 3 is connected with the front end of device for catalytic treatment 4, and device for catalytic treatment 4 rear ends are connected with discharge duct 12.
As shown in Figure 2, it is around the kitchen range top 2 one circles for described annular fume pipeline 3, so that oil smoke tentatively heats oil smoke through the out-of-date heat energy distributing when the kitchen range top 2 is worked that makes full use of.One end of fume pipeline 3 is connected with side-suction type range hood 1 exhaust outlet, and the other end is connected with device for catalytic treatment 4 front ends.
Described device for catalytic treatment 4 as shown in Figure 3, consists of housing 6 and the ceramic monolith 7 that is coated with catalyst 10, after the gas of its rear end after discharge duct 12 will oil smoke be processed, discharges.Wherein: heat-insulation layer 9 is equipped with in the outside of housing 6.Ceramic monolith 7 is attached on the iron net 8 that is fixed on housing 6.
The active ingredient of described catalyst 10 is mainly CuMn

Described temperature control equipment 5 is controlled the reaction temperature of the catalyst 10 in device for catalytic treatment 4, can be by buying on market, and the temperature control equipment that for example model is TC4SP.When temperature surpasses ceiling temperature, temperature control equipment quits work, and when temperature is during lower than lower limit temperature, temperature control equipment heats.Temperature control equipment 5 external stabilities have heat-insulation layer 9, reduce scattering and disappearing of heat.
The course of work that this fume purifying is processed integrated kitchen range comprises pump drainage oil smoke, heating, catalytic treatment and four operations of Exhaust Gas.Oil smoke is sucked by side-suction type range hood 1, under the effect of air exhauster 11, through fume pipeline 3, tentatively heats, and enters device for catalytic treatment 4, carries out catalytic reaction in device for catalytic treatment 4, and simultaneously, temperature control equipment 5 is controlled its reaction temperature in reaction.
During use, first open temperature control equipment 5, the set temperature upper limit and lowest temperature, remain near 350 ℃ of optimum temperatures of reaction temperature, catalytic reaction can be carried out fast, and avoid because excess Temperature causes the generation of catalysqt deactivation phenomenon.
Then open side-suction type range hood 1, oil smoke is sucked by side-suction type range hood 1, and through annular fume pipeline 3, the heat energy distributing while making full use of the kitchen range top 2 work, heats for the first time to oil smoke, has reached the object of economical and energy saving.Oil smoke enters device for catalytic treatment 4 through annular fume pipeline 3 subsequently.Soot gas enters through device for catalytic treatment 4 front ends, through several layers of iron net 8 that is fixed with ceramic monolith 7, when slowing down velocity of liquid assets, carry out catalytic reaction with the catalyst 10 being attached on ceramic monolith 7, the gas that reacts complete is discharged from catalyst treatment device 4 rear ends through discharge duct 12.In catalytic reaction, oil smoke reaction generates carbon dioxide and steam.In course of reaction, temperature control equipment 5 is worked simultaneously.When oil smoke has just entered device for catalytic treatment 4, temperature control equipment 5, to its heat temperature raising, makes it reach 150 ℃ of initiation temperatures catalytic reaction occurs.And the heat discharging in conversion process is used for keeping required catalytic temperature, now, temperature control equipment can, in resting state, when temperature is reduced to lower limit temperature, work on.Asbestos in heat-insulation layer 9 outside device for catalytic treatment, are used for keeping reaction temperature.
At present, the defect that the apparatus for treating cooking fume using on the market exists is: electrostatic adsorption device volume is large, and power consumption is huge, and manual cleaning expense approaches 3000 yuan/time; Petticoat pipe water pouring mode consumes great lot of water resources, and needs to consume a large amount of reagent, and operating cost is expensive.And the utility model is because oil smoke is broken down into carbon dioxide and steam, do not produce secondary pollution, and conversion ratio is high, equipment volume is little, and effects of energy saving and emission reduction is good, and catalyst only needs change once for 1 year, and operating cost is compared lower.As mentioned above, the utility model can better be realized.
The utility model, except above-mentioned embodiment, can also have other structural distortion, and these equivalent technical solutions also should be within its technical protection scope.
