Description
Technical field
The present invention relates to the preheating field of gas medium, specifically a kind of dual circuit combustion type gas preheater.
Background technology
In industrial production, often need gas to carry out preheating, make in making full use of heat some gas preheating of needs, so that the gas of these preheatings is better lighted, or make it participate in heat exchange.
Gas preheater of the prior art is mainly divided into two classes, and a class is to utilize the waste heat preheating gas of flue gas, and another kind is to utilize burning gases to produce heat gas medium is carried out to preheating, the present invention relates to rear a kind of combustion type gas preheater.
Existing combustion type gas preheater is all generally simply will after air and combustion gas mixing, to light, abundant for what burning was carried out, can increase the ratio of air and combustion gas, but but exist the problem that efficiency of combustion is low, and the ratio taking due to air is great, can cause a large amount of combustions heat to be lost, thereby waste the energy, increase cost.
Summary of the invention
For solve the efficiency of combustion that existing combustion type gas preheater exists low, waste energy and problem that production cost is high, the invention provides a kind of dual circuit combustion type gas preheater, utilize a small amount of combustion gas through fully forming a stable thermal source after burning, the gas of needs heating is heated. And gas temperature after preheating can arrive 400-800 DEG C, with the gas after preheating to various ferroalloys and nonmetal heating, as electrolytic manganese, ferrosilicon, flatiron, diamond stone, lime etc.
The present invention solves the problems of the technologies described above the technical scheme of employing to be: a kind of dual circuit combustion type gas preheater, comprise the combustion chamber being communicated with successively, hybrid combustor and temperature controlled compartment, described hybrid combustor is provided with for taking over I to the indoor air that passes into air of mixed combustion, described combustion chamber is provided with two cover gas handling systems, every suit gas handling system includes the mixing chamber of burner and burner connection, described mixing chamber takes over II by the air arranging on it and the mixing that realizes air and combustion gas is taken in combustion gas, and mixed gaseous mixture is transported in burner, on described burner, be also provided with air and take over III.
Described air is taken over I, air is taken in II, air adapter III and combustion gas adapter and is equipped with flow control valve.
The quantity that described air is taken over I is two.
Described air is taken over I, air takes over II and air adapter III realizes air feed by air blast.
In the present invention, the air being entered by air adapter II is taken over after the combustion gas mixing entering forms mist and is lighted in burner with combustion gas in mixing chamber, on burner, be also provided with air and take over III, take over air that III enters and play the effect of auxiliary combustion by air, the gas burning and unburned gas enter into that mixed combustion is indoor to burn away, now, take over I by air and continue wherein to fill into air, so that its burning is more abundant.
Beneficial effect: the present invention's needed air when by fuel gas buring divides three parts to import, had both ensured the adequacy of burning, had also prevented that excess air from introducing the heat causing and losing simultaneously, had improved the utilization rate of the energy that burns. Through test, compared with generic product on present market, can save production cost more than 30%, save the energy 20% left and right.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Reference numeral: 1, combustion chamber, 2, hybrid combustor, 3, temperature controlled compartment, 4, air takes over I, 5, burner, 6, mixing chamber.
Detailed description of the invention
As shown in the figure, a kind of dual circuit combustion type gas preheater, comprise the combustion chamber 1 being communicated with successively, hybrid combustor 2 and temperature controlled compartment 3, the air that described hybrid combustor 2 is provided with for pass into air in hybrid combustor 2 is taken over I 4, described combustion chamber 1 is provided with two cover gas handling systems, every suit gas handling system includes the mixing chamber 6 that burner 5 and burner 5 are communicated with, described mixing chamber 6 takes over II by the air arranging on it and the mixing that realizes air and combustion gas is taken in combustion gas, and mixed gaseous mixture is transported in burner 5, on described burner 5, be also provided with air and take over III.
In the present invention, the hot gas that burning produces enters temperature controlled compartment 3 by hybrid combustor 2, temperature controlled compartment 3 is also provided with blower unit (being made up of air-introduced machine, air hose, flow control valve etc.) and temperature measuring equipment simultaneously, temperature measuring equipment is for detection of gas temperature, and the flow of result adjust flux control valve thus, so that preheating gas temperature meets instructions for use, and be connected with external device by preheating gas interface.
Be more than basic embodiment of the present invention, can on above basis, further improve or limit:
As, described air is taken over I 4, air is taken in II, air adapter III and combustion gas adapter and is equipped with flow control valve, for regulating air inlet;
As, the quantity that described air is taken over I 4 is two, can certainly be other number;
As, described air is taken over I 4, air takes over II and the unification of air adapter III realizes air feed by air blast.
