Abstract
The utility model discloses an air preheater for gas chained preheating furnaces, and the air preheater comprises an outer barrel, the outer barrel comprises a flue gas pipeline, the flue gas pipeline is arranged in a cavity of the outer barrel, the upper part of one side of the outer barrel is provided with a hot air outlet, the lower part of the other side of the outer barrel is provided with a cold air inlet, and the upper and lower ends of the outer barrel are respectively hermetically connected with the pipe wall of the flue gas pipeline. As a further improvement of the utility model, the air preheater also comprises a reinforcing rib, and the upper and lower ends of the outer barrel are used for fixing the reinforcing rib respectively along the circumferential surface of the outer barrel. By using the air preheater for gas chained preheating furnaces disclosed by the utility model, the utilization rate of natural gas is improved; and heat generated by generated high-temperature flue gas is recycled, thereby achieving effects of energy conservation and environmental friendliness.
Description
Technical field
The utility model relates to a kind of air preheater, relates in particular to a kind of air preheater that is used for combustion gas chain type preheating furnace.
Background technology
Energy-conserving and environment-protective, it is that the China and even the whole world are advocated that Litter is carried out recycling, industrial policy and direction that our country also builds a conservation-minded society in propelling.
Using combustion gas chain type preheating furnace at present is to adopt natural gas and air mixed combustion to come that body of heater is carried out preheating to heat; The great amount of high-temperature flue gas that burning produces later just directly is discharged in the air; Because the air themperature of sending in the stove is high more, the combustion rate of natural gas will be high more.Waste for fear of the burning heat energy of the great amount of high-temperature flue gas of generation later, simultaneously natural gas can fully be burnt, we want that the high-temperature flue gas that burning produces is later carried out heat energy to be utilized again, more meets this aim of energy-conserving and environment-protective.
The utility model content
The utility model a kind of air preheater that is used for combustion gas chain type preheating furnace is provided; Can avoiding burning later, the heat energy of a large amount of high-temperature flue gas of generation wastes; These heat energy are carried out preheating to air, improve the combustion rate of natural gas in the combustion gas chain type preheating furnace.
The utility model is realized through following technical scheme: a kind of air preheater that is used for combustion gas chain type preheating furnace; Comprise urceolus; Wherein also comprise flue, be provided with said flue in the cavity of said urceolus, the top of wherein said urceolus one side offers the hot-air air outlet; The bottom of said urceolus opposite side offers the cold air air inlet, and the two ends up and down of said urceolus are tightly connected with the tube wall of said flue respectively.
Further improvement as the utility model is: also comprise reinforcement, the two ends up and down of said urceolus are fixed with said reinforcement along the circumferential surface of said urceolus respectively.
Further improvement as the utility model is: the two ends diameter of said urceolus can be that air is heated evenly and the minimizing noise greater than mid diameter like this.
A kind of air preheater that is used for combustion gas chain type preheating furnace of the utility model; The great amount of high-temperature flue gas that the stove internal combustion produces gets into flue; Cold air gets into the interlayer of urceolus and flue formation from the cold air air inlet; The heat energy that is produced by high-temperature flue gas preheats then to discharge in the hot-air air outlet and gets in the stove and natural gas mixed combustion, because air has temperature, has so just improved the utilization rate of natural gas.
The setting of reinforcement is to stablize solidly more for the structure that improves urceolus, and urceolus adopts insulation material to process and further avoids scattering and disappearing of heat.
A kind of air preheater that is used for combustion gas chain type preheating furnace of the utility model has improved the utilization rate of natural gas, carries out recycle, economical environment-protective to what the high-temperature flue gas that produces produced.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Wherein 1-urceolus, 2-flue, 3-hot-air air outlet, 4-cold air air inlet, 5-reinforcement.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe in detail:
As shown in Figure 1: a kind of air preheater that is used for combustion gas chain type preheating furnace of present embodiment; Comprise urceolus 1, flue 2 and reinforcement 5; Be provided with said flue 2 in the cavity of said urceolus 1; The top of wherein said urceolus 1 one sides offers hot-air air outlet 3, and the bottom of said urceolus 1 opposite side offers cold air air inlet 4, and the two ends up and down of said urceolus 1 are tightly connected with the tube wall of said flue 2 respectively.
The two ends up and down of wherein said urceolus 1 are fixed with said reinforcement 5 along the circumferential surface of said urceolus 1 respectively, and the two ends diameter of the said urceolus 1 in the present embodiment can be that air is heated evenly and the minimizing noise greater than mid diameter like this.
A kind of air preheater that is used for combustion gas chain type preheating furnace of present embodiment; High-temperature flue gas gets into flue 2; Cold air gets into the interlayer that urceolus 1 and flue 2 form from cold air air inlet 4, and the heat energy that is produced by high-temperature flue gas preheats then to discharge for 3 li from the hot-air air outlet and gets in the stove and natural gas mixed combustion.
The beneficial effect of present embodiment is: the heat energy in the flue gas utilizes again, and the combustion rate that has improved has realized environmental protection and saving, and the energy is utilized again.
