Abstract

Provided is a double-pipeline combustion type gas preheater. The double-pipeline combustion type gas preheater comprises a combustion chamber, a mixing combustion chamber and a temperature control chamber, wherein the combustion chamber, the mixing combustion chamber and the temperature control chamber are communicated in sequence, an air connecting pipe I is arranged on the mixing combustion chamber, air is fed into the mixing combustion chamber through the air connecting pipe I, two gas inlet systems are arranged on the combustion chamber, each gas inlet system comprises a combustor and a mixing chamber communicated with the combustor, each mixing chamber is provided with an air connecting pipe II and a fuel gas connecting pipe, mixing between the air and fuel gas in each mixing chamber is achieved through the corresponding air connecting pipe II and the corresponding fuel gas connecting pipe, mixed gas which is formed after the mixing process is conveyed to the combustors, and each combustor is further provided with an air connecting pipe III. According to the double-pipeline combustion type gas preheater, the air which is needed when the fuel gas burns is led into the double-pipeline combustion type gas preheater in a three-part mode, it is ensured that combustion is sufficient, the phenomenon that heat is lost due to the fact that excess air is led in is avoided, and the use ratio of combustion energy is increased. According to tests, compared with a product of the same category in the current market, the production cost can be reduced by more than 30%, and energy can be saved by about 20%.

Description

A kind of dual circuit combustion type gas preheater

Technical field

The utility model 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 when 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, and the utility model 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.

Utility model content

For solve the efficiency of combustion that existing combustion type gas preheater exists low, waste energy and problem that production cost is high, the utility model 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 ℃, with the gas after preheating to various ferroalloys and nonmetal heating, as electrolytic manganese, ferrosilicon, flatiron, diamond stone, lime etc.

The utility model is that the technical scheme that solves the problems of the technologies described above employing is: 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 utility model, 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, by air, take over the effect that air that III enters plays auxiliary combustion, the gas burning and unburned gas enter into that mixed combustion is indoor to burn away, now, by air, take over I and continue wherein to fill into air, so that its burning is more abundant.

Beneficial effect: the utility model needed air when by fuel gas buring divides three parts to import, has both guaranteed the adequacy of burning, has also prevented that excess air from introducing the heat causing and losing simultaneously, has improved the utilization rate of the burning energy.Through test, compare with generic product on present market, can save production cost more than 30%, save the energy 20% left and right.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

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 being communicated with successively, hybrid combustor 2 and temperature controlled compartment 3, described hybrid combustor 2 is provided with for pass into the air of air in hybrid combustor 2 and takes 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 of burner 5 and burner 5 connections, 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 utility model, 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 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 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 utility model, 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;
