Abstract
The utility model belongs to the stove field, and particularly provides an air heating device for a wind inlet of a stove. The air heating device comprises a cooking bench, a furnace, a hearth, an air inlet, the wind inlet and a chimney. The upper portion of the cooking bench is matched with a pot. A stove ring is arranged between the pot and the hearth. The chimney is communicated with the airtight hearth through a smoke exhaust pipe. The air inlet is connected with an external air inlet device through an air inlet pipe. The wind inlet is connected with an external blower through a wind inlet pipe. The air heating device for the wind inlet of the stove is characterized in that an electric heating wire is arranged in the wind inlet pipe, and the tail end of the electric heating wire is of a spiral structure. According to the air heating device for the wind inlet of the stove, the electric heating wire is arranged in the wind inlet pipe and used for preheating air which is about to enter the furnace (after the temperature of the air rises, sufficient burning of the air and fuel gas after being mixed is promoted), the air reaches a certain high temperature when entering the furnace, as a result, burning is more sufficient when the air and the fuel gas are mixed and make contact with each other, emission of nitric oxide and carbon dioxide is reduced, thermal efficiency is improved, and the environmental protection effect is better.
Description
Technical field
The utility model belongs to cooking stove field, is specially a kind of cooking stove air inlet air heating apparatus.
Background technology
Large stove is in the market fried kitchen range and the Chinese food frying-oven ubiquity thermal efficiency is low, energy consumption is large problem, and has other the discharge of harmful substance such as a large amount of nitrogen oxide, carbon dioxide, to kitchen staff's health and environment brings and large injury.Existing kitchen range air intake adopts natural wind, and Cryogenic air directly enters in the chamber of a kitchen range abundant not with combustion gas mixing burning, and the toxic emissions such as nitrogen oxide increase and cause environmental pollution.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of cooking stove air inlet air heating apparatus.
Described cooking stove air inlet air heating apparatus, comprise the kitchen range top, combustion chamber, burner hearth, air inlet, air inlet and chimney, kitchen range top top coordinates with pan, between pan and burner hearth, be provided with stove circle, chimney is communicated with by smoke exhaust pipe with airtight burner hearth, and air inlet is connected with external feed stream device by air inlet pipe, and air inlet is connected with external blower by blast pipe, it is characterized in that, in described blast pipe, electrical heating wire is set, electrical heating wire end is helicoidal structure.
Described cooking stove air inlet air heating apparatus, is characterized in that the spiral part length of described electrical heating wire is 10-20cm.
Described cooking stove air inlet air heating apparatus, is characterized in that the spiral part length of described electrical heating wire is 15cm.
Described cooking stove air inlet air heating apparatus, is characterized in that described electrical heating wire end arranges fin.
Described cooking stove air inlet air heating apparatus, is characterized in that described fin is fin type structure.
The utility model is installed electrical heating wire in blast pipe, to the air preheating that is about to enter combustion chamber (because after air themperature raises, be conducive to combustion gas mixing after abundant burning), while making air enter combustion chamber, reach certain high temperature, during like this with combustion gas mixing catalytic combustion, will be more abundant, reduce the discharge of nitrogen oxide and carbon dioxide, not only improved the thermal efficiency, and environmental protection more.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: the 1-kitchen range top, 2-burner hearth, 3-chimney, 4-electrical heating wire, 5-blast pipe, 6-air blast.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail:
Cooking stove air inlet air heating apparatus, comprise the kitchen range top 1, combustion chamber, burner hearth 2, air inlet, air inlet and chimney 3, the kitchen range top 1 top coordinates with pan, between pan and burner hearth 2, be provided with stove circle, chimney 3 is communicated with by smoke exhaust pipe with airtight burner hearth 2, air inlet is connected with external feed stream device by air inlet pipe, and air inlet is connected with external blower 6 by blast pipe 5.
The interior electrical heating wire 4 that arranges of blast pipe 5, electrical heating wire 4 ends are set to helicoidal structure, and helical structure contributes to improve the efficiency to air heat, and the spiral part length of electrical heating wire 4 is 10-20cm, is preferably 15cm; Also can fin be set at electrical heating wire 4 ends, fin is set to fin type structure, and the contact area of increase and air improves air heat efficiency.
By the air preheating that enters combustion chamber (because after air themperature raises, be conducive to combustion gas mixing after abundant burning), while making air enter combustion chamber, reach certain high temperature, during like this with combustion gas mixing catalytic combustion, will be more abundant, reduced the discharge of nitrogen oxide and carbon dioxide, not only improved the thermal efficiency, and environmental protection more.
In blast pipe, the setting of electrical heating wire, makes intake manifold air temperature be increased to 200 degree from 25 degree even higher, is conducive to the abundant mixed combustion of combustion gas and air, and the thermal efficiency improves more than 40%.
