Abstract
The invention discloses a directly-heated type high-efficiency fuel hot air furnace which comprises a square box body formed by a combustor A and an air mixing chamber B. The combustor A is located inside the air mixing chamber B. A hot air inlet (5) is formed in the upper portion of the air mixing chamber B and used for allowing circulating backflow hot air to enter the air mixing chamber B. A cold air inlet (6) is formed in the lower portion of the air mixing chamber B and used for allowing temperature adjusting cold air to enter the air mixing chamber B. The hot air inlet (5) and the cold air inlet (6) are respectively provided with an air adjusting valve (7). One end of the combustor A is the ignition end and connected with an externally-matched burner (1). The other end of the combustor A is provided with a flow splitting plate (3). The directly-heated type high-efficiency fuel hot air furnace is high in hot air cleanliness, high in temperature rising speed, large in hot air temperature adjusting range, high in heat use rate, low in NOx discharging concentration, compact in structure and convenient to install and maintain.
Description
Technical field
The present invention relates to a kind of heating, air filtering device, being specifically related to a kind of is the directly-heated type high-efficient low polluting combustion of fuel, the warm air oil furnace that high temperature air filters with multiple liquid fuels such as diesel oil, alcohol radical (hydrocarbon) fuel, can obtain the very high high temperature air of cleannes and low NOx drainage, be used for doing the thermal source of conventional drying equipment, needing also to can be used for the occasion of hot-air, as baking room (kiln), baking vanish plastic-blasting room (kiln) and heat cure place, the invention belongs to technical field of drying.
Background technology
In drying system, air heating apparatus is the core, is directly connected to the efficient of drying system and the cleanliness factor of hot-air.Warm air oil furnace has convenient temperature control, sufficient combustion, cleaning as the thermal source of drying equipment, with drying equipment supporting structure compactness, is convenient to realize advantages such as control automatically, warm air oil furnace technical field of drying extensive use at home and abroad at present.
The fuel oil thermal source is made up of three parts usually, and the one, combustor, the 2nd, combustion chamber, the 3rd, air distribution device.Existing fuel oil (combustion gas) hot-blast stove or at the 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, refractory material is adopted in the combustion chamber, form second-time burning with reflector, a kind of direct-fired box warm air oil furnace as the patent No. 201020593975.7, it exists chamber temperature low, and second-time burning is incomplete, lacks the high temperature air filter and can not get high hot air cleaning, therefore, the fuel oil hot air drying system of both at home and abroad the hot-air cleanliness factor being had relatively high expectations at present still adopts the heat exchange type warm air oil furnace.
Summary of the invention
The present invention combines combustor, efficient burning chamber, hot-air filter with air distribution device, constitute a kind of directly-heated type high efficiency fuel hot-blast stove, aim to provide that a kind of sufficient combustion, hot-air cleanliness factor height, NOx concentration of emission are low, air distribution evenly, the wind-warm syndrome adjustable range is big and the warm air oil furnace that is easy to regulate as the employed thermal source of dry run.
The present invention overcomes the above problems the technical scheme that adopts to be: a kind of directly-heated type high efficiency fuel hot-blast stove is made of combustion chamber wallboard 2, flow distribution plate 3, overfiren air port 4, hot blast import 5, cold wind import 6, adjusting valve 7, air outlet 8, wind mixed chamber's wallboard 9 and support 10, forms a square box that is made of combustion chamber A district and wind mixed chamber B district.Combustion chamber A is positioned at the inside of the B of wind mixed chamber.Wind mixed chamber top is provided with hot blast import 5, advance the circulating reflux hot blast, the wind mixed chamber bottom is provided with cold wind import 6, advances temperature adjustment cold wind, import 5 and cold wind import 6 places are provided with adjusting valve 7, and the high temperature gas flow behind backflow hot blast, normal temperature air and the full combustion of fuel is fully mixed in wind mixed chamber.Combustion chamber A is cylindrical shape or square, and the one end is firing tip, and joins combustor 1 outward and is connected, and the other end is provided with flow distribution plate 3.
In the such scheme, wind mixed chamber's inwall is incubated by insulation material, to reduce heat loss.
The invention has the beneficial effects as follows: hot blast cleanliness factor height, programming rate is fast, and hot blast wind-warm syndrome adjustable range is big, the heat utilization efficiency height, the NOx concentration of emission is low, compact conformation, is convenient to I﹠M.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing and embodiment.
Fig. 1 is structural representation of the present invention.
In the above accompanying drawing: 1, combustor, 2, the combustion chamber wallboard, 3, flow distribution plate, 4, overfiren air port, 5, the hot blast import, 6, the cold wind import, 7, adjusting valve, 8, air outlet, 9, wind mixed chamber's wallboard, 10, support.
The specific embodiment
As shown in Figure 1, a kind of directly-heated type high efficiency fuel hot-blast stove is made of combustion chamber wallboard 2, flow distribution plate 3, overfiren air port 4, hot blast import 5, cold wind import 6, adjusting valve 7, air outlet 8, wind mixed chamber's wallboard 9 and support 10, forms a square box that is made of combustion chamber A district and wind mixed chamber B district.Combustion chamber A is positioned at the inside of the B of wind mixed chamber.Wind mixed chamber top is provided with hot blast import 5, advance the circulating reflux hot blast, the wind mixed chamber bottom is provided with cold wind import 6, advances temperature adjustment cold wind, import 5 and cold wind import 6 places are provided with adjusting valve 7, and the high temperature gas flow behind backflow hot blast, normal temperature air and the full combustion of fuel is fully mixed in wind mixed chamber.Combustion chamber A is cylindrical shape or square, and the one end is firing tip, and joins combustor 1 outward and is connected, and the other end is provided with flow distribution plate 3.
In the present embodiment, the flue gas of fuel after combustion chambers burn, adsorption filtration through combustion chamber, flow distribution plate, and formation high temperature clean gas flow enters wind mixed chamber after the second-time burning in combustion chamber wallboard and flow distribution plate overfiren air port zone, mix in wind mixed chamber with the air-flow that enters from hot blast import and cold wind import, thereby guarantee that programming rate is fast, the heat utilization efficiency height.
This device hot-blast stove below 200,000 kilocalories is applied, and the cleannes of hot blast can satisfy the requirement of industries such as clothes, plastic-blasting, baking vanish and metal processing; Programming rate reaches more than 10 ℃/minute; Wind-warm syndrome can be regulated between 70 ℃-600 ℃; Relatively the heat exchange type warm air oil furnace is energy-conservation more than 30%, obtains user's favorable comment.
