Description
Technical field
The utility model relates to a kind of hot-blast stove.
Background technology
Hot-blast stove is a kind of being used for the material that is dried to be carried out heat drying under not contaminated prerequisite, or is applied to the lower heat sensitive material drying of temperature.As: milk powder, pharmacy, synthetic resin, fine chemistry industry etc.The hot-blast stove of traditional structure mainly comprises body of heater, is provided with burner hearth in the body of heater, also is provided with radiating tube in the body of heater, and body of heater is provided with the chimney that is communicated with burner hearth, also is provided with the air inlet and the air outlet of connection on the body of heater.The operation principle of hot-blast stove is, fuel is fully burning in burner hearth, flame after the burning or hot flue gas are before discharging from chimney, radiating tube is heated, the fresh cold air that is transported in the radiating tube from air inlet promptly is heated to form high temperature air, the fresh air temperature is reached more than 1000 degree, and the high temperature fresh air promptly can be used for dried material from air outlet output.Tradition heat exchange wind furnace, simple in structure, heating directly, fresh cold air heats up rapidly, temperature is higher after the heat exchange, weak point is that owing to adopt directly flame or flue gas heating in the burner hearth, the radiating tube life-span is shorter, maintenance cost is higher, has a strong impact on operating efficiency.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure at above-mentioned deficiency, heats up fast radiating tube long service life, and hot-blast stove easy to maintenance.
For solving the problems of the technologies described above, this hot-blast stove comprises body of heater, be provided with burner hearth in the body of heater, also be provided with radiating tube in the body of heater, body of heater is provided with the chimney that is communicated with burner hearth, also is provided with the air inlet and the air outlet of connection on the body of heater, and its design feature is: also be provided with connection air inlet and air outlet heat exchange thorax in the body of heater, described radiating tube is disposed in the heat exchange thorax, and burner hearth is communicated with chimney by radiating tube.
The hot-blast stove of this structure is to realize heating up fast by the extensional mode heat exchange structure, the radiating tube long service life, and easy to maintenance.
The extensional mode heat exchange structure mainly comprises the heat exchange thorax that is arranged on the radiating tube outside, and heat exchange thorax inner chamber and radiating tube inner chamber are isolated, and heat exchange thorax inner chamber is communicated with air inlet and air outlet, and like this, the heat exchange thorax just becomes the passage of fresh air circulation.The two ends of radiating tube are communicated with burner hearth and chimney respectively, and like this, radiating tube just becomes the passage that connects burner hearth and chimney, and will carry out heat exchange in the introducing of the heat in the burner hearth heat exchange thorax.Because the hot flue gas in the burner hearth flows by the radiating tube inner chamber, fresh air is in the radiating tube outside, will be quicker when therefore the heat of hot flue gas is absorbed by the outer fresh air of radiating tube, helps to improve heat exchange efficiency.Flame in the burner hearth or hot flue gas are discharged by many radiating tubes, and for direct dry combustion method radiating tube outer wall, radiating tube is heated and more relaxes, and heat is transmitted more even, in the service life that helps to improve radiating tube, safeguards simpler.
As improvement, fin is arranged uniformly at intervals on the outer wall of described radiating tube.
Fin is set on radiating tube, can increases the area of dissipation of radiating tube, help to improve the heat exchange effect.
As improvement, the quantity of described heat exchange thorax is at least two, be provided with the connection thorax between the adjacent heat exchange thorax, the radiating tube of adjacent heat exchange thorax is serially connected by connecting thorax, and the air outlet of described adjacent heat exchange thorax middle and upper reaches heat exchange thorax and the air inlet of downstream heat exchange thorax are connected together.
The main effect that connects thorax is that adjacent heat exchange thorax is connected together, and like this, no matter several heat exchange thoraxes is arranged, and each heat exchange thorax all will be serially connected successively by connecting thorax, make the stroke of hot flue gas in the heat exchange thorax longer, the heat exchange better effects if.The air outlet of upstream heat exchange thorax is communicated with the air inlet of downstream heat exchange thorax, the heat exchange of increase stroke, time is also arranged, the effect that improves the heat exchange effect.
As further improvement, described connection thorax is provided with the cleaning window.
The cleaning window is set connecting on the thorax, can the easy cleaning radiating tube and connect cigarette ash in the thorax, help to make hot flue gas circulation more smooth and easy.
As further improving, described radiating tube vertically is provided with again.
Radiating tube vertically is provided with, the cigarette ash in the radiating tube is dropped in the connection thorax of radiating tube below naturally, effectively avoid the number of times of cleaning powder heat pipe, help to alleviate maintenance.
As improvement, inboard wall of burner hearth is provided with flame retardant coating.
The main effect of flame retardant coating is to prevent the excessive calcination of the interior flame of burner hearth to body of heater, the service life that helps to improve this hot-blast stove.
As further improvement, roof of the furnace is provided with the fire-resistant training wall of arc of middle part epirelief, and the inlet of radiating tube is positioned at subordinate side, training wall limit.
The main effect of training wall is that the hot flue gas in the burner hearth is played guide functions, and the hot flue gas that makes rising enters in the radiating tube of subordinate side, training wall limit after through the arc water conservancy diversion, has both avoided the dry combustion method radiating tube, makes hot flue gas enter radiating tube smoothly again.
In sum, adopt the hot-blast stove of this structure, rational in infrastructure, heat up fast, the radiating tube long service life, and easy to maintenance, be adapted at various oven dry occasions and use, be particluarly suitable for dry occasion such as medicine, food and use, help to improve drying efficiency.
