Abstract
The invention discloses a double-pipeline burning type gas preheating device which comprises a burning chamber, a mixture burning chamber and a temperature controlling chamber. The burning chamber, the mixture burning chamber and the temperature controlling chamber are communicated in sequence. A first air connecting pipe used for adding air to the mixture burning chamber is arranged on the mixture burning chamber and two sets of air inlet systems are arranged on the burning chamber. Each set of air inlet system comprises a burner and a mixing chamber communicated with the burner. According to each mixing chamber, air and fuel gas are mixed through a second air connecting pipe arranged on the mixing chamber and a fuel gas connecting pipe arranged on the mixing chamber, the mixed gas is conveyed to each burner, and a third air connecting pipe is further arranged on each burner. Air needed when the fuel gas is burnt is guided through three parts, so that the sufficiency of burning is guaranteed, heat loss caused by introduction of excess air is avoided, and the use ratio of burning energy is improved. According to experiments and compared with the same kind of products in the current market, the double-pipeline burning type gas preheating device can save the production cost by over 30% and save energy by about 20%.
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 is carried out to preheating, make some gas preheating that will need when taking full advantage of heat, so that the gas of these preheatings is better lighted, or make it participate in heat exchange.
Gas preheater of the prior art mainly is 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 taken 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 after burning, forming a stable thermal source, the gas that needs are heated is heated.And the gas temperature after preheating can arrive 400-800 ℃, with the gas after preheating to various ferroalloys and nonmetal the 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 be communicated with successively, hybrid combustor and temperature controlled compartment, described hybrid combustor is provided with for to the indoor air that passes into air of mixed combustion, taking over I, described combustion chamber is provided with two cover air inlet systems, every suit gas handling system includes the mixing chamber of burner and burner connection, described mixing chamber takes over II by the air arranged on it and the mixing that realizes air and combustion gas is taken in combustion gas, and mixed gaseous mixture is transported in burner, also be provided with air on described burner 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 entered by air adapter II is taken over after the combustion gas mixing entered forms mist and is lighted in burner with combustion gas in mixing chamber, also be provided with air on burner and take over III, take over by air the effect that air that III enters plays auxiliary combustion, the gas burnt 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 by by fuel gas buring the time divides three parts to import, and has both guaranteed the adequacy of burning, has also prevented that excess air from introducing the heat caused and losing simultaneously, has improved the utilization rate of the burning energy.Through test, with generic product on present market, compare, can save production cost more than 30%, save the energy 20% left and right.
The accompanying drawing explanation
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.
The specific embodiment
As shown in the figure, a kind of dual circuit combustion type gas preheater, comprise the combustion chamber 1 be 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 air inlet systems, every suit gas handling system includes the mixing chamber 6 of burner 5 and burner 5 connections, described mixing chamber 6 takes over II by the air arranged 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, also be provided with air on described burner 5 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 also is equipped with blower unit (being comprised 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 adjust flux control valve as a result thus, so that the preheating gas temperature meets instructions for use, and be connected with external device by the 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 the 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.
