A biomass waste pyrolysis furnace system

Abstract

The invention relates to a cracking furnace system of biomass garbage. The system provided by the invention comprises a furnace body, a feeding mechanism, a slag catching container, a gas washing tower, an oil-gas separating tower and a gas collecting tower; the upper part of the furnace body is provided with the feeding mechanism, the top part is connected with the gas washing tower, the middle part is provided with fire grates, and the bottom part is provided with an agitating blade, an air discharging device and a slag discharging pipe, wherein firstly, the furnace body utilizes more than one layer of fire grate and supplies multiple layers of supporting to be matched with the double-movable-flashboard feeding mechanism and the agitating blade so that the biomass is more completely cracked; secondly, the slag catching container is supplied so that the temperature of high-temperature slag can be reduced and percolate and the like which are produced by the garbage can be all consumed; the generated cracking gas not only is clean and low-temperature, but also can be easier to be separated from oil after the cracking gas passes through the gas washing tower, thereby simplifying theflow of oil-gas separation. According to the system provided by the invention, sewage, oil and steam which are generated in the cracking process can be circulated to the furnace to be combusted and be further cracked so that a harmless treatment is finally achieved.

Description

Technical field: [0001] The invention belongs to the field of biomass waste treatment, in particular to a biomass waste pyrolysis furnace system mainly used for processing domestic waste. Background technique: [0002] Biomass resources are very rich in stock. As a renewable energy source, its reasonable use can not only reduce the environmental burden, but also avoid excessive dependence on traditional coal and fossil fuels. The cracking technology can convert biomass and biomass waste into Combustible gas, as a supplement to energy, is used comprehensively for power generation, heat supply, etc., which is also the main direction of utilization at present. [0003] Furthermore, while the process of urbanization has improved people's living standards, it has also increased the burden of domestic waste, which is also a major problem worldwide. The traditional landfill method is still in use, and the emerging waste incineration treatment has obvious defects. The dioxin gas pr...

Problems solved by technology

This patent only gives a conceptual design, the possibility of realization is not high, and the high-temperature mixed gas discharged from the cracking furnace directly enters the oil and gas separation, and it is difficult to achieve the ideal purpose

[0006] The patent bulletin also discloses many technical schemes related to waste cracking furnaces, most of which are exploratory schemes with poor operability and are difficult to meet the needs of actual production
