Regenerative Combustion Technology realizes that by the periodicity commutation of reversal valve combustion medium and flue gas circulation passage exchange, and then realize fume afterheat to the heat storage accumulation of heat, the heat storage after the accumulation of heat is preheating to higher temperature (800 ℃～1100 ℃) in next commutation cycle with combustion medium; Therefore, heat-accumulation combustion has the effect of energy-saving and emission-reduction, is used in the apparatus for baking in industries such as iron and steel, Non-ferrous Metallurgy, chemical industry, power, glass, pottery, fire-resistant, carbon element.At the difference of combustion medium, the accumulation of heat apparatus for baking is divided into single accumulation of heat apparatus for baking and two accumulation of heat apparatus for baking, and two accumulation of heat apparatus for baking effectively utilize low calorie fuels in the application, are progressively paid close attention to by vast energy conservation person.
Traditional double accumulation of heat apparatus for baking relies on the supply size of regulating air and fuel to realize toasting requirement; With regard to energy-saving and emission-reduction, heat-accumulation combustion mainly by gas jet, entrainment the flue gas of combustion space, realize High Temperature Air Combustion.Therefore, the length of heat-accumulation combustion flame and rigidity are by the kinetic energy decision of gas jet.Change the size of gas flow in the traditional double accumulation of heat apparatus for baking by the effect of electric control valve, will make the gas momentum deficiency of heat-accumulation combustion, and then influence combustion efficiency and energy-saving effect.As seen, satisfy baking process and be difficult to a certain extent satisfy simultaneously with the energy-saving effect of greatly bringing into play heat-accumulation combustion on traditional double accumulation of heat apparatus for baking, the energy-saving potential of two accumulation of heat apparatus for baking has to be excavated.
Along with the transformation of enterprise's technological process of production, to roasting bag quick baking, realize simultaneously energy-saving and cost-reducingly having become that to satisfy modern production institute essential, adopt which kind of apparatus for baking to realize that the baking required value of roasting bag must expect.Though existing traditional double accumulation of heat apparatus for baking has certain energy-saving effect, require to also have big gap apart from enterprise.As seen, in order to satisfy the requirement of roasting bag baking, development and Design New Regenerative apparatus for baking is imperative.
Summary of the invention
The purpose of this utility model provides the two accumulation of heat apparatus for baking of a kind of pulse, and this device is under the prerequisite that satisfies the baking process requirement, and shell is brought into play heat-accumulation combustion gas jet effect to greatest extent, realizes the high efficiency of burning, reduces the energy consumption of baking.
For achieving the above object, the utility model is achieved through the following technical solutions:
The two accumulation of heat apparatus for baking of a kind of pulse, comprise apparatus for baking, temperature measuring equipment, programmable logic controller (PLC), engineer station, air blast, air-introduced machine, fuel channel, air duct, four-way change-over valve, it is characterized in that, install between air blast and the four-way change-over valve and cut valve one (3) soon.
Install between air-introduced machine and the four-way change-over valve and cut valve two (11) soon.
Install between air blast and the air-introduced machine and cut valve three (12) soon.
First interlocking is cut valve (8) soon and is cut the duty that valve (10) existence is closed simultaneously soon with second interlocking.
Compared with prior art, the beneficial effects of the utility model are:
Change traditional double accumulation of heat apparatus for baking and adjust the pattern that thermic load amount size is regulated baking temperature, adopt heat-accumulating burner full-power mode of operation all the time, by regulating the requirement of satisfying baking process burning time of heat-accumulating burner; Change by the heat-accumulation combustion time realizes the baking requirement, changes the adjusting pattern of traditional fuel metering amount, and heat-accumulating burner is worked under the full load state, and the kinetic energy maximum of gas jet is greatly brought into play the energy-saving effect of heat-accumulation combustion.
