Publication number: 20200032151Abstract: A coal pyrolysis process device, including a primary coal pyrolysis device and a secondary coal pyrolysis device, wherein a discharge port of the primary coal pyrolysis device communicates with a feed port of the secondary coal pyrolysis device. When coal is in the primary coal pyrolysis device, coal tar is extracted to the maximum extent, and then enters the secondary coal pyrolysis device. The coal continues to be heated and undergo pyrolysis at an upper portion of the secondary coal pyrolysis device, so that volatile matter of upgraded coal having undergone primary pyrolysis and upgrading are further reduced in the secondary coal pyrolysis device, and more gas is produced.Type: ApplicationFiled: December 7, 2017Publication date: January 30, 2020Applicant: HENAN LONGCHENG COAL HIGH EFFICIENCY TECHNOLOGY APPLICATION CO., LTD.Inventors: Shucheng ZHU, Xibin WANG, Guochao CAO, Mingde LI, Jinfeng LI, Fang LI, Yanwu LV

Patent number: 8945349Abstract: An electrical heating coal material decomposition apparatus includes a closed kiln body with a feed inlet, a discharge outlet, and an electrical heating device arranged in the kiln body. A propulsion and decomposition path of coal material is formed between the electrical heating device and the inner wall of the kiln body. A coal decomposition gas collecting pipe communicates with the propulsion and decomposition path of coal material, and is connected with a gas dust-trapping and liquefying device arranged outside the kiln. The electrical heating device transfers heat to the pulverized coal inside the propulsion and decomposition path of coal material by conduction and irradiation. The pulverized coal absorbs sufficient heat and decomposes into fuel gas, tar gas and coal. The fuel gas and tar gas enters the gas dust-trapping and liquefying mechanism through the decomposed gas collecting tube, where they are collected, dust-trapped, separated and liquefied under pressure.Type: GrantFiled: September 15, 2010Date of Patent: February 3, 2015Assignee: Xixia Dragon Into Special Material Co., Ltd.Inventors: Shucheng Zhu, Xibin Wang, Xiangyun Huang, Guochao Cao, Wei Liu

Patent number: 8864947Abstract: Disclosed is a vertical pyrolysis equipment for coal material, which comprises an enclosed kiln body with an inlet and an outlet, a flame-gas heating pipelines provided inside the kiln body, coal material propulsion and pyrolysis passage formed between the flame-gas heating pipelines and inner wall of the kiln body, coal pyrolysis gas collecting tube communicated with the coal material propulsion and pyrolysis passage provided on the kiln. The heat generated by flame-gas heating pipelines is conducted and radiated to coal powder in the coal material propulsion and pyrolysis passage. The coal powder sufficiently absorbs the heat and is pyrolyzed into fuel gas, tar gas and coal with high heat value inside the coal material propulsion and pyrolysis passage. The pyrolyzed fuel gas and tar gas are transferred to the gas dedusting-liquifying mechanism outside the kiln through the connecting coal pyrolysis gas collecting tube for collecting, dedusting, separating and high-pressure liquefying.Type: GrantFiled: September 19, 2010Date of Patent: October 21, 2014Assignee: Xixia Dragon Into Special Material Co., Ltd.Inventors: Shucheng Zhu, Xibin Wang, Xiangyun Huang, Guochao Cao, Wei Liu

Patent number: 8813823Abstract: An annular clean metal casting mold has a mold body which includes a cold bottom mold plate and a peripheral cold mold plate in connection with the cold bottom mold plate. An annular hot preservation layer is disposed inside the peripheral cold mold plate. A cyclic clean crystalline region is formed between the peripheral cold mold plate and the annular hot preservation layer. A sacrificial crystalline region is formed inside the cyclic hot preservation layer. As the outer race of the annular clean crystallization zone contacts large area of the peripheral low cold mold plate, releasing heat rapidly, while the inner race contacts the annular hot preservation layer 3, heat dissipation is extremely slow, naturally result in forming orientational crystallization.Type: GrantFiled: November 24, 2010Date of Patent: August 26, 2014Assignee: Xixia Dragon Into Special Material Co., Ltd.Inventors: Shucheng Zhu, Xibin Wang, Guochao Cao
