Description

Technical Field

[0001] The utility model relates to the technical field of combustion processing devices, in particular to a high-efficiency combustion device. Background Art

[0002] Biogas is a combustible gas produced by the fermentation of various organic substances under suitable temperature and pH value and isolated from air. Human and animal feces, straw, sewage and other organic substances are fermented under anaerobic conditions in a closed biogas digester, that is, they are decomposed and transformed by a wide variety of biogas fermentation microorganisms to produce biogas. If biogas is not properly handled after accumulation, it is easy to explode, so most of the time, biogas is burned.

[0003] According to a disclosed biogas combustion treatment device (publication number: CN217785156U), the above application uses an air supply pipe tilted downward from the side in conjunction with a fan to continuously provide oxygen support for the blower, so that the ejected biogas can be completely burned. The biogas diverter head is designed to be elevated to prevent children from accidentally touching it. At the same time, the outer side of the diverter head is covered outward by a spherical shell and insulated with heat insulation cotton, which can prevent the outer wall temperature from being too high to scald the user, making it safer to use.

[0004] However, during actual use of the above-mentioned equipment, when the air supply pipe cooperates with the fan to draw external air into the outer shell, the gas can only float upward on one side of the inner shell after flowing through the guide of the air supply pipe. At this time, the air cannot completely fill the entire space inside the outer shell, which will cause the combustion-supporting gas in the air to be unable to be completely mixed with the biogas, which not only affects the degree of mixing of the combustion-supporting gas and biogas, but also affects the efficiency of biogas combustion treatment. In view of this, we have proposed a high-efficiency combustion equipment. Utility Model Content

[0016] Beneficial effects:

[0017] 1. The high-efficiency combustion equipment, through the cooperation of the set fixing rod, fixed shell, support rod, annular pipe, air holes, connecting pipe and gas collecting bucket, allows the air entering the air supply pipe to evenly enter the entire internal space of the outer shell and float upward, avoiding the situation that the air enters the outer shell only through the air supply pipe and can only float upward from one side of the inner shell, and cannot be completely mixed with the biogas, which not only affects the mixing degree of the combustion-supporting gas and the biogas, but also affects the efficiency of the biogas combustion treatment. The air floating upward through the air holes is guided by the cooperation of the set annular inclined baffle and the air guide plate, so that the air spirally floats upward, thereby better mixing with the biogas, further improving the combustion efficiency.

[0018] 2.

DETAILED DESCRIPTION

[0024] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a high-efficiency combustion device, including a base 1, a biogas pipe 2 is fixedly installed on the top of the base 1, an outer shell 3 is fixedly installed on the outside of the biogas pipe 2, an air supply pipe 4 is fixedly installed on the left side of the outer shell 3, a dustproof net is fixedly installed on the left end of the air supply pipe 4, and a fan is fixedly installed inside the air supply pipe 4, which can draw air from the outside into the outer shell 3 to provide combustion aids for the combustion of biogas, an igniter is fixedly installed on the inner wall surface of the upper end of the outer shell 3, a diverter is fixedly installed on the upper end of the biogas pipe 2, biogas can enter the interior of the outer shell 3 through the biogas pipe 2, and air can enter the outer shell 3 through the air supply pipe 4. When air and biogas enter the interior of the outer shell 3, the igniter can be started to ignite the biogas for combustion treatment, a rain shelter 5 is fixedly installed on the top of the outer shell 3, the rain shelter 5 can block rainwater from entering the outer shell 3 to affect the combustion of biogas, and an air intake component is arranged inside the outer shell 3.

[0025] The air intake assembly includes: a fixed rod 601, an annular pipe 604 and an annular inclined baffle 608. The fixed rod 601 is fixedly installed on the outside of the biogas pipe 2. A fixed shell 602 is fixedly installed on the end of the fixed rod 601 away from the biogas pipe 2. The outer wall of the fixed shell 602 is fixedly connected to the inner wall of the outer shell 3. The fixed shell 602 forms a stable fixed structure with the outer shell 3 and the biogas pipe 2 through the fixed rod 601. The gas entering the outer shell 3 through the air supply pipe 4 will completely enter the fixed shell 602.

[0026] A support rod 603 is fixedly installed on the inner bottom surface of the fixed shell 602, and an annular pipe 604 is fixedly installed on the top of the support rod 603. An air vent 605 is opened on the upper surface of the annular pipe 604. When the gas enters the annular pipe 604, it will float evenly to the entire upper space inside the outer shell 3 through the air vent 605. A connecting pipe 606 is fixedly installed on the left end of the annular pipe 604, and an air collecting hopper 607 is fixedly installed on the left end of the connecting pipe 606. The air collecting hopper 607 is located inside the air supply pipe 4, and the outer wall of the air collecting hopper 607 is in contact with the inner wall of the air supply pipe 4. The interior of the gas collecting hopper 607 is interconnected with the interior of the annular duct 604 through the connecting pipe 606. When the fan inside the air supply pipe 4 starts to draw air into the air supply pipe 4, the gas will completely enter the gas collecting hopper 607 and then enter the annular duct 604 through the connecting pipe 606, and float evenly in the entire upper space inside the outer shell 3, thereby preventing the gas from entering the outer shell 3 through only one side of the air supply pipe 4, resulting in the gas only floating on one side of the outer shell 3, which makes it impossible to completely mix with the biogas, thereby affecting the complete combustion and combustion efficiency of the biogas.

[0027] The annular inclined baffle 608 is fixedly installed inside the outer shell 3, and an air guide plate 609 is fixedly installed on the inner wall surface of the annular inclined baffle 608. The bottom surface of the air guide plate 609 is fixedly connected to the upper surface of the fixed shell 602. The air guide plate 609 is arranged in an inclined structure. When the gas floats upward through the air vent 605, it will float in a spiral shape along the inclined surface of the annular inclined baffle 608 and the air guide plate 609 toward the upper end of the biogas pipe 2, which can more evenly fill the entire internal space of the outer shell 3, further improving the mixing degree of air and biogas and the combustion efficiency.

[0028] A rubber ring 701 is fixedly installed at the bottom end of the gas collecting hopper 607. The rubber ring 701 can seal the gap between the gas collecting hopper 607 and the inner wall of the gas supply pipe 4, so that the air can be completely collected inside the gas collecting hopper 607 after entering the gas supply pipe 4. An annular filter plate 702 is fixedly installed on the inner upper end of the outer shell 3. The inner wall of the annular filter plate 702 is fixedly connected to the outer wall of the biogas pipe 2. The annular filter plate 702 can block the particles that fall downward during the biogas combustion process, thereby preventing the particles from entering the annular pipe 604 through the air vent 605 and affecting the upward floating of the air.

[0029] In the utility model, during use, when the fan inside the air supply pipe 4 starts to draw outside air into the outer shell 3, the air will first enter the air supply pipe 4, and then completely enter the air collecting bucket 607, and then the air will enter the annular pipe 604 along the connecting pipe 606, and finally completely enter the outer shell 3 through the air vent 605. When the air reaches the annular inclined baffle 608, it will spirally float upward along the inclined surfaces of the annular inclined baffle 608 and the air guide plate 609, so that the gas can more completely fill the interior of the outer shell 3 and float upward, thereby achieving complete mixing with the biogas, so that the biogas can be more fully burned, thereby improving the efficiency of the combustion treatment.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
