Abstract
The utility model discloses a circulating hot-blast stove of waste gas combustion and indirect heat exchange, which comprises a chamber body, a circulating blower, a combustor, a hearth, a heat exchanger and an electric appliance control device, wherein the chamber body is designed to be a hollow cube, a wall body adopts a double-layer structure, and heat insulating materials are filled in between; an air inlet is arranged at one end of the wall body, and the circulating blower is arranged at the other end; the combustor is arranged at one side of the chamber body, and a smoke exhausting pipe is arranged at the other side; the hearth and the heat exchanger are arranged in a cavity of the chamber body, and the heat exchanger adopts a smoke-gas multi-return structure; the combustor is of a full-automatic dual-purpose type and automatically adjusts the proportions of fuel and combustion air, and the electric appliance control device is designed to automatically run programs at a far distance according to a set temperature value of the output wind of a heated space. Due to the adoption of the hearth with a larger capacity, the utility model enables waist gas to completely burn and hot smoke to sufficiently exchange heat; because the heat exchanger adopts the multi-return structure, the utility model has high heat efficiency, and meanwhile, the utility model has safe operation, high comprehensive efficiency and clearness without pollution.
Description
Technical field
The utility model relates to the burning and the heat transmission equipment of fuel gas, the hot-blast stove of particularly a kind of waste gas burning and indirect heat exchange.
Background technology
At present, the surfaces externally and internally of various device or parts, carry out as the surface of air-conditioning, television set, car crust etc. in the paint line of powder spraying or baking vanish, all need through drying chamber baking processing, the heating equipment of heat temperature raising drying chamber inner circulating air can have electric heater unit, coal-burning installation etc., said method power consumption height, consumption kerosene amount is big, and cost rises; Also useful simple direct-fired waste gas combustion furnace, not energy-conservation, exhaust gas discharged is more, contaminated environment.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of security of operation, energy-efficient waste gas burning and the cycling hot wind furnace of indirect heat exchange are provided.
The purpose of this utility model is achieved in that a kind of waste gas burning and indirect heat exchange cycling hot wind furnace, comprise chamber body, circulating fan, combustor, burner hearth, heat exchanger, electric apparatus control apparatus, the chamber body is set to hollow cube, and wall body adopts double-decker, middle fill insulant material, the side is provided with access door, one end is provided with air intlet, and the other end is provided with circulating fan, and combustor is arranged on a side of chamber body, opposite side is provided with smoke exhaust pipe, and burner hearth and heat exchanger are set in the body cavity of chamber; Heat exchanger adopts the many return structures of flue gas, the design of heat exchanger two ends has porous plate, two porous plates constitute exhaust gases passes with the two ends wall respectively, wherein an end exhaust gases passes is divided into two parts, a part links with burner hearth, another part and smoke exhaust pipe link, and many heat exchanger tube phase communications and liaison are arranged between two porous plates.
The combustion volume design of burner hearth is bigger.
Combustor is full-automatic dual-purpose type, can burnt gas, and also can combustion fuel oil; Fuel and combustion air proportioning are adjusted automatically.
Electric apparatus control apparatus is designed to automatic long-distance working procedure by the output wind-warm syndrome degree that is heated the space, connects that power supply can make that combustor is lighted a fire automatically, the large and small fire conversion, turn-offs and the auto-programming of the security of operation of limiting temperature control voluntarily.
The beneficial effects of the utility model are owing to adopt the combustion chamber of big volume burner hearth, to make waste gas can obtain completing combustion; Because heat exchanger adopts many return structures, thermal efficiency height causes the hot-blast stove circulating fan gateway temperature difference bigger, and opening the back short time is replaceable higher temperature hot blast, and heated air is heated up rapidly; The while security of operation, comprehensive effectiveness height, cleanliness without any pollution.
Description of drawings
Accompanying drawing has provided one embodiment of the present of invention:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the C-C cutaway view of Fig. 1;
Among the figure: 1, air intlet; 2, chamber body; 3, heat exchanger; 4, circulating fan; 5, combustor; 6, smoke exhaust pipe; 7, access door; 8, hot-blast outlet; 9, burner hearth; 10, exhaust gas inlet; 11,12, porous plate; 13, heat exchanger tube
The specific embodiment
In Fig. 1 and Fig. 2, the utility model hot-blast stove, comprise moist closet body 2, embedded circulating fan 4, combustor 5, burner hearth 9, heat exchanger 3, electric apparatus control apparatus, moist closet body 2 is set to hollow cube, wall body adopts double-decker, middle fill insulant material, the side is provided with access door 7, one end is provided with air intlet 1, and the other end is provided with embedded circulating fan 4, and combustor 5 is arranged on a side of moist closet body 2, opposite side is provided with smoke exhaust pipe 6, burner hearth 9 and heat exchanger 3 are set in moist closet body 2 chambeies, and the design of heat exchanger two ends has porous plate 11,12, two porous plates 11,12 constitute exhaust gases passes with the two ends wall respectively, wherein the exhaust gases passes of porous plate 11 1 ends is divided into two parts, a part links with burner hearth 9, and another part and smoke exhaust pipe 6 link, and many heat exchanger tubes 13 phase communications and liaison are arranged between two porous plates.
The combustion volume of burner hearth 9 is bigger, makes the negative pressure flame and the flue gas flow direction that are formed by smoke exhaust pipe 6 smooth and easy even, and waste gas is longer in the stable thermal-flame district holdup time, and burning fully.
Heat exchanger 3 adopts the many return structures of flue gas, and its effective heat exchange area increases, and the coefficient of heat transfer improves;
Combustor 5 is full-automatic dual-purpose type, can burnt gas, also can combustion fuel oil, and fuel and combustion air proportioning are adjusted automatically, the less drift of swirl flame that burner hearth 9 internal combustion districts are formed, flameholding greatly improves fuel thermal efficiency.
Electric apparatus control apparatus is designed to automatic long-distance working procedure by the output wind-warm syndrome degree that is heated the space, connects that power supply can make that combustor is lighted a fire automatically, the large and small fire conversion, turn-offs and the auto-programming of the security of operation of limiting temperature control voluntarily.
During the utility model work, with the waste gas of collecting after quantitative analysis meets relevant requirements, after exhaust gas inlet 10 is by combustor 5 igniting, send into the burning of hot-blast stove burner hearth 9 thermal-flame districts, high-temperature flue gas after this burning flows to by heat exchanger 3 with three backhauls of S shape, with heat exchanger 3 outer contact carry out thermal energy exchange by circulating fan 4 from the circulating air of air intlet 1 suction after, deliver in the drying chamber that is heated workpiece by wind tube outlet 8 by circulating fan 4 again.
The utility model is fuel used except that combustible exhaust gas, also can use fuel oil, fuel oil directly and combustor 5 oil plant inlet tubes link, the technological process after the ignition is same as described above.
