Patent number: 10864487Abstract: The present invention discloses a novel sand mixing device, including an electric motor and a hydraulic system, wherein the electric motor is used as the power source of the hydraulic system, and the hydraulic system drives all the actuating elements in the sand mixing device. Beneficial effects: in the present invention, the traditional diesel engine drive mode is changed into a motor drive mode and a hydraulic system is maintained, and the power is all in the form of an electro-hydraulic system, realizing the advantages of environmental protection and energy saving with the electric motors as the power source, also taking into account the advantages of small size and flexible layout of the drive parts of the hydraulic system. Therefore, the issues of not environmental-friendly, large size, inconvenient transportation, well site layout, and maintenance in the application of traditional sand mixing device can be addressed.Type: GrantFiled: July 17, 2020Date of Patent: December 15, 2020Assignee: American Jereh International CorporationInventors: Maomao Han, Shuwei Li, Weiwei Liu, Mingsheng Li, Xiangxiang Ren, Changli Li, Binggang Yang

Patent number: 9833762Abstract: An ethylene cracking furnace is provided. The ethylene cracking furnace includes at least one radiant section. The at least one radiant section includes bottom burners and/or sidewall burners, and at least one radiant coil arranged in the radiant section. The radiant coil includes at least an upstream pass tube and a downstream pass tube, the upstream pass tube being configured as an inner tube, and the downstream pass tube being configured as an outer tube surrounding the inner tube and having a closed end. The inner tube defines an inner space forming an upstream flow path. A gap defined between the inner tube and the outer tube forms an downstream flow path.Type: GrantFiled: October 12, 2011Date of Patent: December 5, 2017Assignees: China Petroleum & Chemical Corporation, SINOPEC Engineering IncorporationInventors: Xiou He, Jingkun Liu, Changli Li, Hainü Shen, Yuping Guo, Chen Shao

Patent number: 9604193Abstract: The present disclosure provides an ethylene cracking furnace, comprising at least one radiant section provided with a bottom burner and/or a side burner, and at least one set of radiant coil arranged along a longitudinal direction of the radiant section. The radiant coil is an at least two-pass coil having an N?1 structure, wherein N is preferably a natural number from 2 to 8. A manifold is arranged at an inlet end of a downstream tube of said at least two-pass coil, and an outlet end of each upstream tube of said at least two-pass coil is connected to the manifold through a curved connector. The arrangement according to the present disclosure can effectively reduce the expansion differences between the upstream tubes and the downstream tubes, and therefore reduce the stress caused thereby. Consequently, bending of the radiant coil can be avoided, thereby extending the service life of the radiant coil.Type: GrantFiled: October 28, 2015Date of Patent: March 28, 2017Assignees: CHINA PETROLEUM & CHEMICAL CORPORATION, SINOPEC ENGINEERING INCORPORATIONInventors: Xiou He, Jingkun Liu, Changli Li, Hainu Shen, Yuping Guo, Chen Shao

Patent number: 8900522Abstract: The invention relates to an ethylene cracking furnace having a multi-pass radiant coil, comprising at least one radiant section. In the radiant section there are provided with bottom burners and/or sidewall burners, and at least one set of multi-pass radiant coil longitudinally arranged in the radiant section. The multi-pass radiant coil is a four- to ten-pass type radiant coil. At least one tube of the multi-pass radiant coil is arranged to be spatially adjacent to a tube which is not consecutive to said at least one tube. With this arrangement, the thermal radiation influence between tubes with high temperature can be reduced, so that the tubes with low temperature can absorb the radiation heat from the tubes with high temperature. Therefore, the surface temperature of the tubes with high temperature can be reduced, thus extending the lifetime of the radiant coil and the operational cycle of the cracking furnace.Type: GrantFiled: October 26, 2010Date of Patent: December 2, 2014Assignees: China Petroleum & Chemical Corporation, SINOPEC Engineering Incorporation, China Petroleum & Chemical Corporation, Beijing Institute of Chemical IndustryInventors: Xiou He, Changli Li, Zhaobin Zhang, Jingkun Liu, Mujun Yuan, Cong Zhou, Yuping Guo, Yonghua Zhao, Hainü Shen
