Compared with the prior art, the fuel gas hot blast stove has the advantages that the heat exchange area is large, the heat exchange efficiency is high, the combustion cost is low, the working condition is stable, the size is small, and the installation and the transportation are convenient.
Description
Technical field
the utility model relates to a kind of hot-blast stove, specifically the preventing freeze in winter fuel gas hot-blast stove of a kind of grain, tobacco oven dry or mine shaft.
Background technology
Hot-blast stove is to utilize fuel (blast furnace gas, coke-stove gas, coal gas of converter, mixed gas, producer gas natural gas, oil liquefied gas heavy oil, diesel oil and organic waste etc.) to discharge chemical energy in stove internal combustion, Cryogenic air is heated to the thermal power transfer equipment of the high temperature air of uniform temperature.
Existing gas hot-air furnace structure is more single, especially, on heat exchange mode, adopts fuel after combustion chambers burn more, and flue gas is discharged after the tubular type of 2 ~ 3 backhauls or plate-type heat-exchange.Adopt the equipment of this kind of heat exchange mode heavy, take up room larger, exist service life of short duration simultaneously, the drawbacks such as maintenance inconvenience.
Summary of the invention
The utility model is heavy in order to solve existing gas hot-air furnace structure, and the problem large and short inconvenience maintenance of life-span that takes up room, provides a kind of preventing freeze in winter fuel gas hot-blast stove especially.
In order to address the above problem, the utility model is taked following technical scheme: a kind of preventing freeze in winter fuel gas hot-blast stove, comprise combustion chamber, Heat Room and hot-blast stove shell, hot-blast stove shell one side is provided with cold wind import, and hot-blast stove shell upside is provided with hot-blast outlet, and hot-blast stove enclosure is provided with combustion chamber and Heat Room, combustion chamber one side is provided with burner, combustion chamber is connected with Heat Room by bellows, and Heat Room upside is provided with exhanst gas outlet, and exhanst gas outlet is communicated with atmosphere.
Described bellows is spirally coiled in outside, combustion chamber.Bellows is on the one hand as the passage of high-temperature flue gas, and low the expanding with heat and contract with cold of landing damages body of heater on the one hand.
Described combustion chamber is provided with expansion joint, and outside, combustion chamber is welded with fin.Expansion joint damages effect as low the expanding with heat and contract with cold of a part of landing of combustion chamber to body of heater, and fin plays fixed combustion chamber and thermolysis.
Combustion gas fully mixes with air, by burner, light, then blast in combustion chamber and fully burn and produce high-temperature flue gas, high-temperature flue gas in combustion chamber, realizes convection current and the bellows through being connected with chamber front end enters into Heat Room, and after heat exchange, flue gas enters atmosphere from being positioned at the exhanst gas outlet of hot-blast stove afterbody top through chimney.And cold wind is sent into from being positioned at the cold wind import of hot-blast stove afterbody by pressure fan, by Heat Room, combustion chamber skin, fin, bellows, the hot blast that reaches rated temperature is transported to user from being positioned at the hot-blast outlet discharge of hot-blast stove front end top.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, on heat exchange area, compare with hot-blast stove in the past, this kind of combustion chamber of hot-blast stove area is larger, the use of bellows in addition, thus make the heat exchange area of this kind of hot-blast stove obtain very large increase;
2, on structure innovation, in order to overcome the injury of expanding with heat and contract with cold body of heater is caused when hot-blast stove is worked, in combustion chamber, increase on the one hand the expansion joint of some, with bellows, replace the fixedly flue that originally there is no retractility on the other hand;
3, on heat exchange efficiency, along with the increase of heat exchange area, the heat of high-temperature flue gas is absorbed fully, heat exchange efficiency also improves thereupon;
4, economically, because the raising of heat exchange efficiency, the heat of combustion gas is fully absorbed, thereby has reduced burning cost in burning;
5, compare with the hot-blast stove of equal-wattage, operating mode is more stable, volume is less, installs, transports more convenient.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
1-hot-blast outlet in figure, 2-combustion chamber, 3-burner, 4-bellows, 5-expansion joint, 6-fin, 7-exhanst gas outlet, 8-Heat Room, the import of 9-cold wind ,-10-hot-blast stove shell.
The specific embodiment
as shown in Figure 1, a kind of preventing freeze in winter fuel gas hot-blast stove, comprise combustion chamber 2, Heat Room 8 and hot-blast stove shell 10, hot-blast stove shell 10 1 sides are provided with cold wind import 9, and hot-blast stove shell 10 upsides are provided with hot-blast outlet 1, and hot-blast stove shell 10 inside are provided with combustion chamber 2 and Heat Room 8, combustion chamber 2 one sides are provided with burner 3, combustion chamber 2 is connected with Heat Room 8 by bellows 4, and Heat Room 8 upsides are provided with exhanst gas outlet 7, and exhanst gas outlet 7 is communicated with atmosphere.
Described, bellows 4 is spirally coiled in 2 outsides, combustion chamber.
Described, combustion chamber 2 is provided with expansion joint 5, and 2 outsides, combustion chamber are welded with fin 6.
Combustion gas fully mixes with air, by burner 3, light, then blast the interior abundant burning in combustion chamber 2 and produce high-temperature flue gas, high-temperature flue gas in combustion chamber, realizes convection current and the bellows 4 through being connected with chamber front end enters into Heat Room 8, and after heat exchange, flue gas enters atmosphere from being positioned at the exhanst gas outlet 7 of hot-blast stove afterbody top through chimney.And cold wind is sent into from being positioned at the cold wind import 9 of hot-blast stove afterbody by pressure fan, by Heat Room 8, combustion chamber 2 skins, fin 5, bellows 4, the hot blast that reaches rated temperature is transported to user from being positioned at hot-blast outlet 1 discharge of hot-blast stove front end top.
