Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection machinery, and more specifically, relates to a continuous feeding double-layer pyrolysis device. Background Art

[0002] In order to protect the environment, organic pollutants in life need to be thermally decomposed to reduce the harm of organic pollutants to the environment. A double-layer pyrolysis device is required for the thermal decomposition of organic pollutants. The organic pollutants are discharged from the feed port into the double-layer pyrolysis device. The double-layer pyrolysis device thermally decomposes the organic pollutants. After the pyrolysis is completed, the organic pollutants are discharged from the discharge port.

[0003] According to CN202120297166.X, the present invention discloses a double-layer pyrolysis furnace, which relates to technical fields such as petrochemical industry and hazardous waste treatment, including an upper pyrolysis chamber and a lower pyrolysis chamber. A high-temperature flue is provided on the outside of the upper pyrolysis chamber, a spiral conveying shaft is provided inside the upper pyrolysis chamber, a combustion chamber is provided on the outside of the lower pyrolysis chamber, a burner is installed on the side wall of the combustion chamber, a combustion chamber outlet is provided on the top of the combustion chamber, and the combustion chamber outlet is connected to the flue inlet. A feed port is provided on the top of the upper pyrolysis chamber, an upper furnace body material outlet is provided at the bottom of the upper pyrolysis chamber, a feed spiral is provided at the left end of the lower pyrolysis chamber, a lower furnace body material inlet is provided at the top of the feed spiral, a kiln tail is provided at the right end of the lower pyrolysis chamber, and a discharge port is provided at the bottom of the kiln tail.

[0004] Based on the above, the feed port on the existing double-layer pyrolysis device is set on the upper side of the device. When the staff discharges organic pollutants into the feed port, the staff needs to continuously lift the organic pollutants to the feed port, and then discharge the organic pollutants into the inside of the feed port. The staff constantly carry the organic pollutants, which consumes a lot of physical energy and is cumbersome to operate. After working for a period of time, it is difficult to feed continuously and stably, which affects the pyrolysis efficiency of the pyrolysis device. Utility Model Content
