Patent number: 8251571Abstract: An inline mixer structure that is compact and has a high mixing efficiency is provided. In an inline mixer structure that forms a fluid mixture by evenly mixing and diffusing different types of fluid, a cylindrical mixer body (10) that is provided with a space portion (11) that passes therethrough in an axial direction, and a plug-shaped member (20) that is integrated by being inserted from the upstream side of the space portion (11) are provided. A chemical fluid and pure water are mixed and diffused after merging inside the space portion, where the chemical fluid is radially discharged toward a space portion (11) because the downstream end portion of a chemical fluid flow path (21) that is formed in an axial direction of the plug-shaped member (20) is closed, and pure water flows in from an eccentric fluid flow path formed so as to pass through the outer peripheral surface of the mixer body (10) at a position offset from the axial center of the space portion cross-section.Type: GrantFiled: May 15, 2008Date of Patent: August 28, 2012Assignee: Surpass Industry Co., Ltd.Inventor: Hiroshi Imai

Patent number: 8215823Abstract: A cement mixing method for mixing cement used in cementing oil wells casing and the mixer used in that method. The mixer employs a straight bulk cement inlet, five annular recirculation jets and five annular water jet orifices located downstream of the recirculation jets so that all of the jets discharge at an angle towards the mixing chamber and the discharge from the water jet orifices intersects with the flow from the recirculation jets. This five jet, intersecting flow design allows for more thorough wetting of the cement powder with a smaller, lighter, less expensive and more durable mixer that is less inclined to foul and easier to clean.Type: GrantFiled: August 16, 2011Date of Patent: July 10, 2012Assignee: Estate of Thomas E. AllenInventor: Thomas E. Allen

Patent number: 8206652Abstract: The present invention provides a flow duct type jet reactor and a process for preparing isocyanates using it. The flow duct type jet reactor situates flow ducts in inner feed pipe which form whirlpool and reinforce vortex, thereby amine steam rapidly admixes and reacts with phosgene, and the byproducts are reduced. In addition, the present process uses a jet-absorption apparatus which rapidly cools the high temperature gas discharged from the reactor to a temperature at which the product is thermally stable, and at the same time provides negative pressure for the reaction process of the system, and thus saving bulky vacuum system.Type: GrantFiled: August 21, 2007Date of Patent: June 26, 2012Assignee: Ningbo Wanhua Polyurethanes Co., Ltd.Inventors: Yonghua Shang, Zhongping Sun, Jianfeng Li, Yong Wang, Weiqi Hua, Deqiang Ma, Yongsheng Wang, Jiansheng Ding

Publication number: 20120069698Abstract: A mixer for mixing immiscible fluids includes a mixer housing defining a flow passage therethrough from a first fluid inlet to an outlet thereof. An upstream portion of the flow passage defines a main longitudinal axis. A second fluid inlet is provided downstream of the first fluid inlet in fluid communication with the upstream portion of the flow passage. The second fluid inlet is offset with respect to the main longitudinal axis of the flow passage to introduce fluid along a path that is offset with respect to the main longitudinal axis for inducing swirl on fluids introduced at the first and second fluid inlets. In certain embodiments, a mixer section is included having a flow constriction defined in a downstream portion of the flow passage with a flow area smaller than that of the upstream portion of the flow passage for enhancing turbulent mixing of fluids therein.Type: ApplicationFiled: September 17, 2010Publication date: March 22, 2012Applicant: Delavan IncInventors: Spencer D.
