Abstract
The invention discloses a double fuel gas cycle hot blast stove of waste gas direct combustion and indirect heat transfer, which comprises a chamber, a cycle fan, a combustor, a hearth, a heat exchanger and a computer control device, wherein the chamber is set to be a hollow cube, a wall body adopts a double-layer structure, the middle is filled with a heat insulating material, one end is provided with an air inlet, while the other end is provided with the cycle fan; the combustor is arranged on one side of the chamber, and the other side of the chamber is provided with a smoke venting pipe; the inside of a cavity of the chamber is provided with the hearth and the heat exchanger which adopts a smoke gas multiple return structure; the combustor has a fully automatic double type, and a mixing ratio of fuel to combustion air can be automatically adjusted; and the computer control device is designed into automatic distant range programming operation according to a temperature set value output by a heating space. Because the stove adopts the hearth with larger volume, waste gas can be fully combusted, and hot smoke gas can be subjected to full heat transfer; because the heat exchanger adopts the multiple return structure, the heat exchanger has high heat efficiency; and the stove has safe operation, high comprehensive effectiveness, clean and no pollution.
Description
Technical field
But the present invention relates to the combustion heat-exchange equipment of fuel oil and combustion gas, particularly a kind of double fuel gas cycle hot blast stove of waste gas direct combustion and indirect heat transfer.
Background technology
At present, the surfaces externally and internally of various device or parts, as air-conditioning, battery truck, automobile, carry out in the paint line of powder spraying or baking vanish on the surface of Refrigerator housing etc., all need to toast processing through in the drying chamber of drying oven, provide thermal source by combustor, circulation heating in the heat temperature raising drying chamber, electric heater unit is arranged, coal and oil device etc., said method power consumption height, consumption kerosene amount is big again, the heat energy utilization rate is not high, not energy-conservation, can not be applicable to the needs that the current modernization industry of China develops as this drying oven, create conservation-minded society, must walk the road of " scientific and technical innovation ", reach effects of energy saving and emission reduction.
Summary of the invention
The objective of the invention is to overcome above deficiency, a kind of easy to operate, security of operation is provided, energy-efficient, the double fuel gas cycle hot blast stove of waste gas direct combustion and indirect heat transfer that automaticity is high.
The technical scheme that the present invention solves its technical problem employing is: a kind of double fuel gas cycle hot blast stove of waste gas direct combustion and indirect heat transfer, contain the body of having family, circulating fan, combustor, burner hearth, heat exchanger, computer controller, the chamber body is set to hollow cube, wall body adopts double-decker, middle fill insulant material, the side is provided with access door, one end is provided with air intlet, the other end is provided with circulating fan, 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.
This cycling hot wind furnace has adopted the integrated innovation technology, the volume of combustion chamber is designed big (different with other stove combustion chamber), waste gas energy holdup time in 680 ℃ of-760 ℃ of stable combustion chambers is longer, the waste gas that does not have incomplete combustion exists, improve the thermal efficiency, reach energy-conservation effect.
Combustor is full-automatic dual-purpose type, can burnt gas, and also can combustion fuel oil; Fuel and combustion air proportioning are adjusted automatically, improve fuel thermal efficiency to greatest extent.
Computer controller is designed to automatically remote sequencing operation by the desired temperature that is heated space output, connects power supply and can make that combustor is lighted a fire automatically, large and small fire can be changed automatically, turn-off voluntarily and the auto-programming of limiting temperature control security of operation.
The invention has the beneficial effects as follows,, make waste gas can obtain completing combustion owing to adopt the combustion chamber of big volume; 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
Concrete structure of the present invention is drawn by following examples and accompanying drawing thereof:
Fig. 1 is the double fuel gas cycle hot blast stove of waste gas direct combustion and indirect heat transfer structural representation:
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
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in detail:
In Fig. 1 and Fig. 2, cycling hot wind furnace of the present invention, contain moist closet body 2, embedded circulating fan 4, combustor 5, burner hearth 9, heat exchanger 3, computer controller, 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, the other end is provided with embedded circulating fan 4, combustor 5 is arranged on a side of moist closet body 2, and opposite side is provided with smoke exhaust pipe 6, and burner hearth 9 and heat exchanger 3 are set in moist closet body 2 chambeies.
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 smooth and easy even, and waste gas is longer in the stable thermal-flame district holdup time, and sufficient combustion, complete externally can not pollute.
Heat exchanger 3 adopts the many return structures of flue gas, and its effective heat exchange area increases, and heat exchange effect coefficient 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.
Computer controller is designed to automatically remote sequencing operation by the desired temperature that is heated space output, connects power supply and can make that combustor is lighted a fire automatically, large and small fire can be changed automatically, turn-off voluntarily and the auto-programming of the security of operation of limiting temperature control.
When this circulating air furnaceman does, 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.
This cycling hot wind furnace is fuel used except that combustible exhaust gas, also can use fuel oil directly and combustor 5 oil plant inlet tubes link, directly can burn can not pollute.Heat exchange structure does not contact heated circulated air with flue gas, keep clean.
