Description

Novel gasification cyclone combustion device

Technical Field

The invention relates to the technical field of organic matter, solid waste and straw combustion devices, in particular to a novel gasification cyclone combustion device.

Background

With the increasing environmental demands of countries around the world, there are stringent requirements for carbon emissions and greenhouse gas emissions. The urban and rural remote areas are piled up with a large amount of solid waste of straw, branches, fallen leaves and other organisms, which is most likely to cause fire, and huge disasters are brought to people, even ecological chains are unbalanced. However, most of the existing treatment methods are to mix-burn in landfill or open air and crush the materials to prepare particles; the large industrialization mode has large investment and high logistics cost, is easy to cause secondary pollution, such as oil consumption of motor vehicles and direct discharge of tail gas into the atmosphere, and causes serious harm to the surrounding environment and the bodies of people.

In the development of the technology for treating straw and biomass solid waste in the past decades, related departments and related enterprises in China use a plurality of different modes for treating the straw and biomass solid waste, and the technology of comprehensive recycling is utilized, so that the emission pollution is reduced. For example, straw and biomass solid waste power generation, granulating after crushing, open burning and the like, but the straw and biomass solid waste power generation and granulating are always the most effective methods. However, the turnover, transportation and manpower costs are too high in the whole process of collection, transportation and storage, but the turnover, transportation and manpower costs cannot be popularized.

In the related art, the solid straw can be burnt in a civil combustion furnace, the combustion furnace is provided with a cylindrical furnace wall, a hearth is arranged in the furnace wall, a furnace mouth is arranged above the furnace wall, a smoke outlet is arranged on the side wall above the furnace wall, and a grate is arranged at the lower bottom of the hearth in the furnace wall. When the straw fuel is used, straw fuel is placed above a grate in a hearth and ignited, primary air enters from the lower part of the grate, a pot or a water heater is placed on a furnace mouth, the straw fuel in the hearth is burnt by the primary air, heat is generated to heat the pot or the water heater, smoke generated by combustion is discharged from a smoke outlet, and when the straw fuel is combusted by the combustion furnace, enough primary air enters from the lower part of the grate to be beneficial to combustion of the straw fuel in the hearth. Most crop straws are burnt and characterized in that flames are not easy to generate when the crop straws are burnt, volatile components volatilize firstly when the crop straws are burnt and then charred to generate smoke, the volatile components and the smoke are combustible matters, the burning furnace is not provided with a secondary air port, the combustible volatile components and the smoke are not burnt, the generated combustible volatile components and smoke are discharged along with the smoke from a smoke outlet, and if primary air is large enough, the volatile components and the smoke can be burnt, but the flames in a hearth can be made to rush upwards, so that the flames are difficult to utilize, and because crop straws are compacted and put into a grate, the interior of the straw fuels is difficult to contact combustion air when the crop straws are burnt, the volatile components and the charred smoke are difficult to generate when the crop straws are burnt. In addition, natural wind is adopted to support combustion in the market, the combustion furnace in the prior art cannot effectively and fully burn crop straw fuel, a large amount of volatile components and smoke are discharged during combustion, the discharged volatile components and smoke are harmful gases and pollute the surrounding environment, and the traditional combustion furnace has the problems of insufficient combustion of fuel gas and insufficient fire intensity.

Therefore, the novel gasification cyclone combustion device has the advantages of excellent performance, low cost, household use, and other purposes such as cooking, heating, water heating, steam power generation and the like by additionally generating heat energy.
