Description

Technical Field

[0001] The utility model relates to the technical field of hot blast furnaces, in particular to a hot blast furnace of a multi-roller type domestic garbage pyrolysis and gasification device. Background Art

[0002] With the acceleration of urbanization, the output of domestic waste continues to increase. How to effectively deal with domestic waste has become an environmental and resource issue that needs to be solved urgently. Traditional waste disposal methods, such as landfill and incineration, have many disadvantages. Landfill occupies a large amount of land resources and may cause soil and groundwater pollution. Although incineration can reduce the volume of garbage, it is easy to produce harmful pollutants such as dioxins. Pyrolysis gasification technology, as an emerging waste treatment technology, converts organic matter in garbage into usable energy, such as combustible gas, at a relatively low temperature, reducing the emission of harmful gases.

[0003] There are still some problems with the hot air furnace of the existing multi-roller domestic waste pyrolysis and gasification device. During the pyrolysis and gasification process, the uniformity of the heating of the garbage has a key impact on the pyrolysis and gasification efficiency. If too much garbage is input at one time and it cannot be heated evenly, some organic matter will not be fully pyrolyzed, reducing the effect of garbage treatment and energy recovery efficiency. At the same time, a large amount of waste heat will be generated during the pyrolysis and gasification process. If this part of the waste heat cannot be effectively recycled and utilized, it will cause energy waste and increase operating costs. Utility Model Content

[0007] As a further improvement of the above solution, an air intake pipe is fixedly connected to the surface of the hot blast stove, a valve is provided inside the air intake pipe, and a combustion chamber body is provided inside the hot blast stove.

[0008] The above technical solution preheats the oxygen, raising the temperature of the oxygen entering the pyrolysis gasifier, which helps improve the efficiency of waste pyrolysis. The valve setting allows for flexible adjustment of the oxygen input as needed, facilitating control of the pyrolysis process.

[0009] As a further improvement of the above solution, a heat exhaust pipe is fixedly connected to the upper surface of the combustion chamber body, and the heat exhaust pipe is located below the guide pipe.

[0010] As a further improvement of the above solution, the outer surface of the guide pipe is fixedly connected to a pipe bracket, and the pipe bracket is fixedly connected to the outer surface of the hot blast stove.

[0011] The above technical solution ensures the stability of the guide tube and prevents the guide tube from being deformed or shifted due to its own weight or external factors.

[0012] As a further improvement of the above solution, a garbage inlet groove is provided on the upper surface of the pyrolysis gasification furnace, and a waste discharge groove is provided on the lower surface of the pyrolysis gasification furnace, and a valve is provided inside the waste discharge groove.

[0013] Through the above technical solution, the garbage inlet chute provides an entrance for garbage to enter the pyrolysis gasification furnace, making it convenient for garbage to be put into the furnace. The waste discharge chute and its valve can reasonably control the discharge of solid residues, facilitating the management of waste after pyrolysis.

[0014] As a further improvement of the above solution, an exhaust pipe is fixedly connected to the upper surface of the pyrolysis gasification furnace, and a filter box is fixedly connected to the top end of the exhaust pipe.

[0015] Through the above technical solution, the gas generated by pyrolysis is filtered and treated to prevent untreated harmful gases from being directly discharged into the environment, thereby playing a role in protecting the environment.

[0016] As a further improvement of the above solution, a filter mesh group is provided inside the filter box, and a discharge hole is opened on the upper surface of the filter box.

[0017] Through the above technical solution, the filter group effectively filters impurities and other harmful substances in the pyrolysis gas, and the filtered gas is discharged through the exhaust hole, making the exhausted gas cleaner and reducing pollution to the environment.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The utility model uses a servo motor to drive the transmission shaft, causing the stirring support rod group to rotate and stir the garbage, ensuring that the garbage is fully exposed to the high temperature. This helps the garbage to be heated evenly in the pyrolysis gasification furnace, promotes the pyrolysis reaction of organic matter in the garbage, and improves the overall efficiency of pyrolysis gasification, so that the organic matter in the garbage can be decomposed into volatile gases and a small amount of solid residue more quickly and completely. The recovery pump extracts the waste heat from the pyrolysis gasification furnace through the waste heat recovery pipe and uses it to heat the water in the water storage tank. This design effectively utilizes the waste heat generated during the pyrolysis gasification process, reduces heat energy waste, improves the energy utilization rate of the entire device, and reduces operating costs.
