Embodiment Construction

[0023] The structure of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0024] A kind of biogas burner of the present invention comprises: injector and nozzle; figure 1 As shown, the mouth of the nozzle is provided with several small-diameter passages, and the inner cavity of the nozzle is straight cylindrical. The several small apertures in the mouth are arranged in a quincunx shape and are connected, such as figure 2 As shown, the nozzle cavity is tapered. Or the several small apertures in the mouth are separated in a ring shape, such as image 3 As shown; the annular small-aperture multi-layer setting, the inner aperture is small, and the outer aperture is large, such as Figure 4 shown.

[0025] Such as Figure 5 and 6 As shown, the inlet end of the introduction section is uniformly provided with a circle of small holes along the side wall (only one small hole is shown in the figure), so th...

Abstract

The invention relates to a biogas burner, which includes an ejector and a nozzle. The biogas burner is characterized in that the ejector includes a lead-in section and mixing section which are coaxially arranged; the caliber of the mixing section is more than that of the lead-in section so as to form a clearance and lead in air for mixing; the mouth part of the nozzle is provided with a pluralityof channels with small calibers which are arranged in a plum blossom shape and are communicated; or a plurality of channels with small calibers are arranged in a circular shape separately; the circular-shaped channels with small calibers are arranged in multi-layers; the calibers of the inner layer are small and the calibers of the outer layer are big. The inlet end of the lead-in section is uniformly provided with a circle of small holes along a side wall; the upper port of the mixing section is uniformly provided with a circle of small holes along the side wall. The mixing section or the lead-in section is provided with swirling flow sheets; and the upper port of the mixing section is provided with a gridded flame holder. The biogas burner solves a plurality of problems like safely and effectively burning biogas in current fermentation biogas processing and utilizing system with none pollution, etc.

Description

technical field [0001] The invention relates to the structure of a burner, in particular to a biogas burner. Background technique [0002] Fermentation biogas is the gas produced by anaerobic fermentation of waste such as domestic garbage, feces, sludge, sewage, etc. It is mainly composed of methane, carbon dioxide, water vapor and various trace impurities. [0003] The collection and utilization of fermented biogas has been paid more and more attention by people, and because these gases are all from waste fermentation, they are renewable energy sources, their utilization and consumption can not only replace non-renewable fossil fuels, but also reduce greenhouse gases emissions. [0004] However, in the fermentation biogas treatment and utilization system, due to the mismatch between gas production and gas consumption, it is often necessary to set up incineration equipment to burn off excess gas. In addition, due to the above-mentioned waste treatment process, sewage with ...
