Description

Technical Field

[0001] The invention relates to the technical field of oven equipment, in particular to a full-heat heating oven burner. Background Art

[0002] In existing technologies, whether using clean combustion (dust-free combustion) or dirty combustion (dust-containing combustion), chimneys exhaust high heat externally. The heat generated by combustion is not fully converted. The resulting structure is complex, requiring a lot of material (the larger the heating surface and the heat-generating surface, the higher the heat conversion efficiency, which naturally requires more material). Manufacturing labor is also labor-intensive. Even with expensive products, much of the unconverted heat is discharged outside the production workspace in the form of exhaust fumes, wasting significant energy and increasing equipment energy consumption. According to data, most thermal equipment boasts a thermal efficiency of 80% to 90%, but in reality, most achieve only around 17%. The remaining 83% of heat is wasted as hot smoke. In summary, this results in expensive products being purchased while wasting heat. The purpose of purchasing equipment and fuel is essentially to buy heat for production, which is a misnomer. The high cost of the equipment is unjustified, but the heat required for production is not generated. This leads to high operating costs and low efficiency. Because existing furnace chimneys exhaust heat externally, the high combustion efficiency and the labor required to monitor the fire increase significantly. Therefore, existing combustion equipment technology is a highly uneconomical model. Summary of the Invention

[0016] Figure 2 This is a structural diagram of a dusty full-heat furnace head;

[0017] In the figure: 1, oven body 2, stove 3, heat supply pipe 4, uniform distributor 5, induced draft fan 6, smoke clean pipe 7, ash discharge port 8, first cylinder 9, second cylinder. DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the present invention is not limited thereto.

[0019] Example 1:

[0020] like Figure 1 As shown, the dust-free full-heat stove head includes an oven body 1. A heat supply pipe 3 is provided at the bottom of the oven body 1. One end of the heat supply pipe 3 passes through the outside of the oven body 1 and is connected to the stove 2 to receive the heat generated by the combustion of the stove 2. The other end of the heat supply pipe 3 transports the heat to the top of the oven body 1 and is connected to the distributor 4, so that the heat in the heat supply pipe is output to the inner cavity of the oven body 1 through the distributor 4, and a circulating fan is provided in the oven body 1.

[0021] This embodiment can be used for burners of clean fuels, such as oil and gas, which are heated in a dust-free combustion mode. When the oil and gas fuel burners are burning, they are generally dust-free and smokeless. The high-temperature flue gas generated by the fire is transported to the distributor on the top of the oven body under the action of the bridge heat supply pipe. The hot gas dissipates a part of the heat through a certain length of the heat supply pipe surface and then cools down to a certain degree before reaching the distributor. The distributor evenly distributes the remaining high-temperature flue gas and outputs it to the interior of the oven body, dissipating the heat to the inner cavity of the oven. Then, under the action of the circulating fan inside the oven body, the heat is evenly blown through every corner of the oven body, and the products to be dried in the air-heat drying oven are completely dried. The heat in the oven body does not waste any heat at all and quickly reaches the desired temperature. The harmful gases such as carbon dioxide and carbon monoxide in the combustion exhaust gas deposited inside the oven body must be discharged to the outside and supplemented with cold air under the condition of increasing the heat to maintain the safety of the air inside the oven.

[0022] Example 2:

[0023] like Figure 2 As shown, the dust-free full-heat burner includes an oven body 1, a first cylinder 8 is provided inside the oven body 1, the bottom of the first cylinder 8 is connected to the bottom of the oven body 1, the top of the first cylinder 8 is connected to the distributor 4 provided on the top of the oven body 1 through the clean smoke pipe 6, and the clean smoke pipe 6 is provided with an induced draft fan 5; wherein the first cylinder 8 is further provided with a second cylinder 9 suspended on the top of the first cylinder 8, and an annular cavity is formed between the outer wall of the second cylinder 9 and the inner wall of the first cylinder 8, and the heat generated by the combustion of the stove 2 outside the oven body 1 is transmitted to the top of the first cylinder 8 through the heat supply pipe 3 and is connected to the annular cavity.

[0024] The bottom of the first cylinder 8 is provided with an ash storage chamber, and the ash storage chamber is provided with an ash discharge port 7 connected to the outside of the oven body 1. When ash discharge is not required, the ash discharge port 7 is closed.

[0025] The inner diameter of the second cylinder 9 is 1.5 times or more of the inner diameter of the clean smoke pipe 6 .

[0026] The distance between the inner wall of the first cylinder 8 and the outer wall of the second cylinder 9 is 0.5-1.5 times the inner diameter of the clean smoke pipe 6.

[0027] The spreader 6 is a smoke exhaust hole evenly spaced apart on the heat delivery pipe.

[0028] The dust-carrying burner head of this embodiment, when working, produces dirty dust during solid fuel combustion, and is transported along with the flue gas through the heat delivery pipe to the side of the top of the first cylinder and into the annular cavity between the first cylinder and the second cylinder. The negative pressure draft generated by the inclined installation at the inlet or the pulling effect of the induced draft baffle and the induced draft fan will form a rotating wind rotating around the second cylinder in the annular cavity. Under the action of the rotating inertia, the rotating wind will throw the dust particles slightly heavier than the hot flue gas to the inner wall of the first cylinder, and slowly fall after rubbing against the inner wall of the first cylinder. Under the pulling force of the lower opening of the second cylinder, the rotation gradually moves downward, and after breaking away from the constraint of the second cylinder and becoming larger, the wide environment at the bottom will gradually slow down the inertia of the rotating flue gas, and the ability to carry gravity dust will decrease. The dust can break away from the constraint of the wind and slowly settle and accumulate at the bottom of the first cylinder. After the wind force of the induced draft fan breaks away from the constraint of the diameter of the second cylinder, the air The air in the oven is heated up and the air is blown away by the heat of the oven cylinder, which in turn causes the oven to freeze after a period of about 2 hours. Due to the simple structure of the present invention, the addition of the housing and fan makes it a superior hot air furnace. Despite this, all technologies inspired by the present invention are protected by the invention, including the naturally high smoke extraction design without induced draft fans. All references to the invention, which require no intellectual effort, are protected by the invention. Due to the minimal fuel consumption, simple structure, and low cost of the present invention, it saves energy and money while also significantly reducing carbon emissions, achieving multiple beneficial effects and producing incredible benefits.
