Description

The heat accumulating type evaporation burner

Technical field

The invention relates to a kind of burner, relates to a kind of alcohol-group fuel heat accumulating type evaporation burner of vaporization combustion voluntarily that adopts particularly.

Background technology

At present, in when culinary art, industry such as restaurant especially, the used energy that burn mostly is natural gas, liquefied gas, cost height not only, and also along with the exploitation of the energy, resource is minimizing gradually also.Also have and adopt diesel oil to burn, but, influence health of people, and have the cost height equally, the problem of a resource shrinkage because smell is big.

Along with development of science and technology, the scientific research personnel develops low cost in succession, resource is alcohol-group fuel widely, but existing burner is because the problem of its structure, can not adopt alcohol-group fuel to burn, also there is producer to design burner and can adopts alcohol-group fuel, but its combustion system adopts spray burning, and the shortcoming of existence is: efficiency of combustion is low, and flame temperature is low, about 1000 ℃, what adopt is the spray burning mode, thereby the particle that produces of atomizing back can not completing combustion, along with flue gas can fall into food cooked, and alcohol-group fuel to be compound have certain toxicity, thereby limited the application of alcohol-group fuel in culinary art.

Summary of the invention

In order to overcome the above problems, the invention provides a kind of heat accumulating type evaporation burner.The mode of alcohol-group fuel vaporization combustion is adopted in the invention, sufficient combustion not only, and the temperature height of generation, energy savings reduces user's cost.

To achieve these goals, the technical scheme of the invention employing is: a kind of heat accumulating type evaporation burner is characterized in that comprising economizer bank, main body, heater, breather pipe I, injection type nozzle, breather pipe II and collection chamber; Described main body is an annular, and main body is made the vaporizer that inside has sealing, and the zone that body inner surface surrounded forms the combustion chamber; The outer surface of main body is provided with heater, economizer bank places the upper end of main body, and communicate with vaporizer, the end of breather pipe I passes main body and inserts in the vaporizer, the other end communicates with collection chamber, and breather pipe II one end communicates with collection chamber, and the other end is connected with the injection type nozzle, the injection type nozzle is connected with main body, and stretches in the combustion chamber.

Described injection type nozzle is made: inner shape of through holes is two coaxial round platforms, and the small end face of two round platforms overlaps, the angle α that the plane, upper end of the side of last round platform and injection type nozzle forms is 70～89.5 °, and the angle β that the plane, lower end of the side of following round platform and injection type nozzle forms is 35～90 °.

The beneficial effect of the invention is:

1, sufficient combustion.Pass through heater, temperature of vaporization chamber is reached more than 65 ℃, alcohol-group fuel enters vaporizer by economizer bank, the vaporization of being heated, alcohol-group fuel gas enters collection chamber through breather pipe I, enters the injection type nozzle by breather pipe II, light gas, burning, because employing is that the vaporization mode is burnt, thereby sufficient combustion.

2, ignition temperature height.Owing to adopt unique injection type nozzle, the shape of through holes of nozzle interior is two coaxial round platforms, and the small end face of two round platforms overlaps, the angle α that the plane, upper end of the side of last round platform and injection type nozzle forms is 70～89.5 °, and the angle β that the plane, lower end of the side of following round platform and injection type nozzle forms is 35～90 °.Thereby at the bottom of burning rear nozzle formation negative pressuren zone, air enters in the nozzle by the bottom of nozzle, mixes by a certain percentage with alcohol-group fuel gas, makes that burning is more abundant, and burning back flame temperature can reach 1300 ℃.

3, energy savings.Adopt heater heating vaporizer during beginning, in case after the burning, just can close heater, and utilize the waste heat in the combustion chamber vaporizer can be heated, and because economizer bank places the upper end of main body, flame can be with at first preheating of the alcohol-group fuel in the economizer bank, alcohol-group fuel after the preheating enters vaporizer again, can vaporize fast and enter collection chamber, satisfy the burner sustained combustion, make full use of the energy.

4, reduce cost.Because the alcohol-group fuel resource is extensive, cost is low, has not only reduced user's cost of material, is waste heat after the burning and the vaporization thermal source adopts, has reduced user's energy cost equally.

The specific embodiment

As Fig. 1～shown in Figure 4, a kind of heat accumulating type evaporation burner comprises economizer bank 1, main body 2, heat-insulation layer 3, heater 4, breather pipe I 6, injection type nozzle 7, breather pipe II 8, collection chamber 9.

Main body 2 is an annular, and main body 2 is made the vaporizer 5 that inside has sealing, and the zone that main body 2 inner surfaces are surrounded forms combustion chamber 10; The outer surface of main body 2 is provided with heater 4, in order better to play the effect of insulation, between main body 2 and heater 4 heat-insulation layer 3 is set.

Economizer bank 1 places the upper end of main body 2, and communicate with vaporizer 5, the end of breather pipe I 6 passes main body 2 and inserts in the vaporizer 5, the other end communicates with collection chamber 9, breather pipe II 8 one ends communicate with collection chamber 9, the other end is connected with injection type nozzle 7, and injection type nozzle 7 is connected with main body 2, and stretches in the combustion chamber 10.

Injection type nozzle 7 is made: inner shape of through holes is two coaxial round platforms, and the small end face of two round platforms overlaps, the angle α that the plane, upper end of the side of last round platform and injection type nozzle 7 forms is 85 °, and the angle β that the plane, lower end of the side of following round platform and injection type nozzle 7 forms is 40 °.What certainly α can be in 70～89.5 ° is arbitrarily angled, and what β can be in 35～90 ° is arbitrarily angled.

The operation principle of the invention is: during use, at first connect heater, body temperature is reached more than 65 ℃, alcohol-group fuel enters in the vaporizer by economizer bank, the vaporization of being heated, gas enters in the collection chamber through breather pipe I, enters in the injection type nozzle by breather pipe II, light gas, along with burning of gas, negative pressuren zone is formed on the bottom of injection type nozzle, in the air flow nozzle, along with mixing of air and alcohol-group fuel gas, it is more abundant to burn, and flame temperature raises, and the burning indoor temperature also raises in succession, close heater this moment, with the waste heat heating vaporizer of combustion chamber, flame is with the alcohol-group fuel preheating in the economizer bank simultaneously, and the alcohol-group fuel that enters like this in the vaporizer is vaporized fast, enter in the collection chamber, satisfy the burner sustained combustion.
