Exhaust hood for biomass energy converter

Abstract

The invention discloses an exhaust hood for a biomass energy converter. The exhaust hood for the biomass energy converter comprises a hood body (1) in which a cavity is formed, and is characterized in that: a plurality of grooves (3) are distributed at the periphery of an outer surface of the hood body (1); and exhaust holes (5) are reserved on side walls (4) of the grooves (3) and are communicated with the cavity in the hood body (1). The exhaust holes are reserved on the side walls of the grooves formed on the outer surface of the hood body, so wind enters a combustion chamber in a centrifugal radiation shape to form rotary wind, and a combustible material in the combustion chamber can be combusted sufficiently; the opening direction of the exhaust holes is changed to the horizontal direction from the conventional vertical direction, so the blockage due to dust is avoided; and through the structure, the gas generation performance is greatly improved.

Description

technical field [0001] The invention relates to a biomass energy conversion device for converting bio-organic fuel into combustible gas, in particular to a biomass energy conversion furnace ventilation hood. Background technique [0002] With the rapid development of my country's economy, the gap between the supply and demand of oil, natural gas, coal and other resources has increased year by year, and the price has also continued to rise. Many farmers are reluctant and cannot afford expensive gas and coal. Therefore, a kind of biomass energy conversion burner that improves the utilization rate of renewable energy appears on the market at present, so that the rural areas can use clean and cheap new energy. However, due to the unreasonable structure of the air diffuser device in the existing biomass energy conversion furnace, the air diffuser effect is poor. During use: when the wind generated by the blower passes through the diffuser device, the wind direction can only flow...

AI Technical Summary

Problems solved by technology

However, due to the unreasonable structure of the air diffuser device in the existing biomass energy conversion furnace, the air diffuser effect is poor.

During use: when the wind generated by the blower passes through the diffuser device, the wind direction can only flow vertically, so that the combustion materials in the combustion chamber of the biomass conversion furnace located on the upper floor can only be burned vertically along the wind direction, while the lower part and the upper layer surround The combustion materials are not completely burned, resulting in low efficiency of the biomass conversion furnace, and the open flame will not work after the materials are burned for 20-40 minutes

Moreover, the direction of the air guide hole of the traditional air diffuser is easy to be blocked by the carbon ash generated during the high temperature reaction process of the combustion material, which directly affects the work of the biomass conversion furnace
