Embodiment 1

As shown in the figures 1 and 2, the embodiment of the present invention 1 provides a kind of pyrolytic high-efficient purification barbecue device, including car body 1, it is arranged on the operating board 2 on described car body 1 and is arranged on the oven 3 on described operating board 2, in described car body 1, being provided with cigarette Road 4, described oven 3 bottom end is provided with the smoke inlet connected with described flue 4 one end, the charcoal on fire grate in oven 3 The oil smoke that first food produced by fire carries out primary combustion decomposition, and when oil smoke is decomposed the most completely, remaining oil smoke is inhaled Receive in flue 4；Described car body 1 also includes the air exhaust box 5 being arranged on described operating board 2, sets bottom described air exhaust box 5 one end There is the outlet flue connected with described flue 4 other end, in described air exhaust box 5, be longitudinally provided with oil smoke near one end of described flue 4 Purifier 6, fume purifier of fume 6 can carry out second-time burning decomposition to the oil smoke entered in air exhaust box 5, it is achieved thereby that will Oil smoke is discharged after being fully cleaned up；On described air exhaust box 5, the top, one end away from described outlet flue is provided with exhaust outlet 7, described flue 4 Inside being provided with extractor fan 8, extractor fan 8 is mainly used in absorbing in flue 4 oil smoke；In described flue 4 near described in enter cigarette Mouthful one end be provided with volume damper 9, volume damper 9 can be adjusted by the air quantity in flue 4；Described air exhaust box 5 is close One end of described exhaust outlet 7 is provided with heat sink 10, and described air exhaust box 5 top is stretched out on described heat sink 10 top.Cooling dress Put 10 arrange and mainly the high-temperature gas after purifying is carried out cooling process, prevent high-temperature gas to be expelled directly out, scald pedestrian.

During barbecue, car body 1 can be shifted onto outdoor, light the charcoal fire in oven 3, when extractor fan 8 carries out convulsion, There is provided sufficient oxygen for charcoal burning, therefore, it is possible to strengthen the burning of charcoal fire, improve barbecue efficiency, when roasting, food simultaneously On oil stain be dropped on charcoal fire, charcoal fire can carry out preliminary combustion decomposition to oil stain, and now, the oil smoke amount of generation is less, When charcoal fire amount is less, the oil oozed out in food and the flavoring oil of interpolation then drop in oven 3, thus can not be by charcoal fire Preliminary exposition, now oil smoke amount increases, and oil smoke is adsorbed onto in flue 4 by extractor fan 8, enters and passes through oil smoke to air exhaust box 5 Purifier 6 is discharged after carrying out sufficient combustion decomposition, and this device structure is simple, not only increases barbecue efficiency, and can The oil smoke produced by food is sufficiently cleaned up, more environmentally-friendly, healthy.

The present invention uses lower air draft combustion-supporting, and the oil smoke that barbecue produces prolongs air draft and flows to bottom oven through charcoal fire, quilt Pyrolytic processes for the first time, additionally, equipment is with volume adjusting apparatus, air quantity is adjustable, and firepower is controlled.Through charcoal fire for the first time The oil smoke overwhelming majority after process is decomposed, and also has and is not decomposed from the lacunary gap of crowd of oven double-edged fine-toothed comb on a small quantity, quilt It is immediately discharged to oven bottom.When high temperature is mixed with the mixed gas of a small amount of oil smoke, the pyrolytic flowing through its upper side purifies dress When putting, moment completes secondary and decomposes completely, it is achieved that the complete combustion decomposition of oil smoke.

This equipment is without dismantling and cleaning, non-maintaining, can realize manual temperature control, twice combustion decomposing, purifying, it is possible to thoroughly fired by oil smoke Burning and decompose, this equipment uses simple, and the life-span is long.

Car body local do isothermal holding, it is ensured that operator barbecue operating process in from radiation injury.

The food using this barbecue device to burn paper as sacrificial offerings is the vividest, more environmentally-friendly, the pollution that no smoke fire burns, barbecue efficiency with Other barbecue devices are compared, and efficiency improves at least 3 times.
