Description
Technical field
The utility model relates to a kind of large-scale heating, air filtering device, be specifically related to a kind of large-scale take the direct-heating efficient combustion with reduced pollutants that the Multi liquid fuels such as diesel oil, alcohol radical (hydrocarbon) fuel are fuel, the warm air oil furnace that high temperature air filters, for making the thermal source of conventional drying equipment, also can be used for needing the occasion of hot-air, as baking room (kiln), baking vanish plastic-blasting room (kiln) and heat cure place, belong to technical field of drying.
Background technology
In drying system, air heating apparatus is core, is directly connected to the efficiency of drying system and the cleanliness factor of hot-air.Warm air oil furnace, as the thermal source of drying equipment, has convenient temperature control, sufficient combustion, clean, compact with drying equipment supporting structure, is convenient to realize the advantages such as automatic control, warm air oil furnace technical field of drying extensive use at home and abroad at present.
Fuel oil thermal source is comprised of three parts conventionally, and the one, combustor, the 2nd, combustion chamber, the 3rd, air distribution device.Existing fuel oil (combustion gas) hot-blast stove or at combustion zone air distribution, combustion zone temperature is lower, is unfavorable for full combustion of fuel, as the high efficiency fuel fuel gas hot-blast stove of the patent No. 200420016992.9; Or combustion zone and air distribution distinguish from, combustion chamber adopts refractory material, with reflector, form second-time burning, as a kind of direct-fired box type oil hot air furnace of the patent No. 201020593975.7, it exists chamber temperature low, second-time burning is incomplete, lacks high temperature air filter and can not get high hot air cleaning.The hot-air filter air filtration amount of a kind of direct-heating efficient warm air oil furnace of patent 201320200639.5 is little, only be suitable for middle-size and small-size directly-heated type warm air oil furnace, the fuel oil hot air drying system of therefore, both at home and abroad hot air cleaning degree being had relatively high expectations at present still mainly adopts heat exchange type warm air oil furnace.
Summary of the invention
The utility model combines combustor, efficient burning chamber, hot-air filter with air distribution device, form a kind of large-scale direct-heating efficient warm air oil furnace, aim to provide a kind of high-power, sufficient combustion, hot air cleaning degree is high, NOx concentration of emission is low, air distribution evenly, wind-warm syndrome adjustable range is large and warm air oil furnace that be easy to regulate uses as dry run thermal source.
The utility model is to overcome the above problems adopted technical scheme to be: a kind of large-scale direct-heating efficient warm air oil furnace, by combustion chamber wallboard, wind mixed chamber's wallboard forms a casing consisting of combustion chamber and wind mixed chamber, combustion chamber is positioned at the inside of wind mixed chamber, combustion chamber firing tip with join combustor outward and be connected, on the wallboard of combustion chamber, have overfiren air port, wind mixed chamber top is provided with hot blast import, bottom is provided with cold wind import, tail end is provided with air outlet, described combustion chamber tail end cover has a flow distribution plate support, 2 above flow distribution plates are installed on flow distribution plate support, on flow distribution plate, be distributed with a plurality of air ports.
Preferably, between described flow distribution plate and air-out direction, be formed with the angle of 15 °～30 °.
Preferably, described flow distribution plate is along center line symmetry arrangement.
Preferably, described flow distribution plate is provided with two-layer along air-out direction.
The beneficial effects of the utility model are: the utility model is by having additional flow distribution plate at combustion chamber tail end, make flue gas after burning when the flow distribution plate, the flue dust on the one hand can adsorbed fuel burning producing, in combustion chamber, there is in addition higher ignition temperature, can also make the flue gas behind combustion chamber in air port, form second-time burning when flowing through flow distribution plate, NOx concentration of emission is low, and hot blast cleanliness factor is high, compact conformation, is convenient to I&M.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the embodiment 1 flow distribution plate top view of arranging.
Fig. 3 is the embodiment 2 flow distribution plates top views of arranging.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, shown in Fig. 2, a kind of large-scale direct-heating efficient warm air oil furnace, by combustion chamber wallboard 2, wind mixed chamber's wallboard 9 forms a casing consisting of combustion chamber A and the B of wind mixed chamber, combustion chamber A is positioned at the inside of the B of wind mixed chamber, combustion chamber A firing tip with join combustor 1 outward and be connected, on the wallboard of combustion chamber, have overfiren air port 4, the B of wind mixed chamber top is provided with hot blast import 5, bottom is provided with cold wind import 6, hot blast import 5, cold wind import 6 is provided with adjusting valve 7 and regulates intake, tail end is provided with air outlet 8, described combustion chamber A tail end cover has a flow distribution plate support 11, 4 flow distribution plates 3 are installed on flow distribution plate support 11, on flow distribution plate 3, be distributed with a plurality of air ports 12, between flow distribution plate and air-out direction, be formed with the angle of 15 °～30 °, flow distribution plate is along center line symmetry arrangement.
