Description
Technical field
The utility model belongs to Energy Saving for Industrial Furnace environmental technology field, is related to a kind of gas industry stove, more particularly, to
It is a kind of by recycling the waste heat preheated air of combustion tail gas, and pass through intelligent control natural gas and the air that has been warmed up is real
It is existing fully premixed so as to being optimal energy saving and environment protecting gas industry stove.
Background technology
Increasingly strict with national environmental protection policy, the industrial furnaces such as metallurgical and heat treatment do fuel using natural gas has been
Trend of the times.Existing gas industry stove, the tail gas after combustion heating are directly discharged generally by chimney, heat loss compared with
Greatly；Or combustion gas and air are not uniformly mixed before catching fire by stoichiometric ratio in advance, combustion reaction is incomplete, and burning is inadequate
Fully；Or do not heat the air for participating in premix in advance, ignition temperature cannot improve.These present situations cause existing day
Right gas industrial furnace energy consumption is higher, and the energy saving space is wide.
The content of the invention
The technical problem to be solved by the utility model is to provide it is a kind of can recycle waste heat from tail gas, burning fully, heat
It can the high energy-saving gas industry stove of utilization rate.
Technical solution is as follows used by the utility model solves above-mentioned technical problem：Intelligent power saving industrial gas furnace, bag
Furnace body and Combustion System case are included, burner hearth is provided in the furnace body, the burner hearth is provided with into burner, thermocouple and tail gas
Discharge port, the burner that enters are provided with burner, air-fuel ratio valve, the air-fuel are provided with before the burner
Gas electromagnetic valve is provided with before proportioning valve；The thermocouple is arranged at the inner wall of burner hearth；The tail gas discharge port is set
Heat exchanger is provided on the outside of the middle and upper part of burner hearth, tail gas discharge port, the heat exchanger is provided with hot-wind inlet, hot wind goes out
Mouth, heat exchanging chamber, fresh air inlet and fresh air outlet.The hot-wind inlet is connected with furnace off-gas discharge port, and the fresh air enters
Air blower is provided on the outside of mouthful, fresh air outlet is connected with the air intlet of burner.The Combustion System case is provided with
Temp controlled meter, frequency converter and ignition controller, the temp controlled meter are connected respectively with thermocouple, frequency converter and ignition controller, institute
The frequency converter stated is connected with air blower, and the ignition controller is connected with gas electromagnetic valve.
Heat exchanger is provided at the tail gas discharge port of the burner hearth.The high-temperature tail gas of burner hearth is made to enter heat exchanger through overheat
Outwards excretion again, takes full advantage of high-temperature tail gas and the fresh air that will participate in burning is heated, heat greatly improved after exchange
The utilization rate of energy.
The fresh air outlet of the heat exchanger is connected with the air intlet of burner.Fresh air after heat exchanger heats its
Temperature is increased to 500-650 DEG C, these high temperature fresh airs make the flame temperature of burner greatly improve, and reaches so as to significantly shorten burner hearth
Time needed for design temperature, while the consumption of combustion gas is greatly decreased, realize energy-efficient purpose.
The temp controlled meter is connected with frequency converter, and the frequency converter is connected with air blower.Temp controlled meter according to burner hearth or by
Treated signal and instruction are sent to frequency converter by the difference condition between the temperature for heating object and the temperature that is previously set,
Frequency converter controls the rotating speed of blower motor accordingly, air pressure and the air quantity of the air for participating in burning is also just controlled, in air-fuel ratio
Under example valve collective effect combustion gas and air is made to be uniformly mixed in advance by optimal stoichiometric ratio before catching fire so that combustion reaction
Completely, while by the output quantity of dynamic control combustion gas adjust the size of firepower, closer to design temperature when firepower it is smaller, reach
The minimum firepower of the temperature can be maintained by being automatically kept after to design temperature, be disappeared so as to avoid the useless energy to greatest extent
Consumption.
Compared with prior art, the utility model has the advantage of：The intelligent power saving designed according to said program fires
Gas industrial furnace, the high-temperature tail gas that when heating object of the device in heating furnace and burner hearth generates, is introduced into heat exchanger process
Outwards excretion again, takes full advantage of high-temperature tail gas and the fresh air that will participate in burning is heated, greatly improved after heat exchange
The utilization rate of thermal energy；Meanwhile the fresh air after heat exchanger heats its temperature is increased to 500-650 DEG C, these high temperature fresh airs ginseng
With burning ignition temperature is made to greatly improve, so as to which the consumption of combustion gas be greatly decreased；Further, since combustion gas and air are pre- before catching fire
It is first uniformly mixed by optimal stoichiometric ratio so that combustion reaction is complete；Firepower and the output quantity of combustion gas are according to heating temperature
It needs intelligently to adjust, so as to reduce the consumption of combustion gas to greatest extent, makes to whole energy-saving effect and reach more than 30%.
