Patent number: 10207215Abstract: There is provided an active coke regeneration mixed vapor treatment method. The method comprises the following process steps of: A) performing a first water condensation on a mixed vapor produced during an active coke regeneration process by spray water in a first condensation zone; B) performing a second water condensation on the mixed vapor that is after the first water condensation by spray water in a second condensation zone, to further condensate and purify the mixed vapor; C) eliminating moisture in a gas through mist elimination from the gas fraction in the mixed vapor that is after the second water condensation, and discharging the remaining gas from the upper of the second condensation zone; and, D) discharging active coke micro powder in the mixed vapor that is after the second water condensation, with condensation water. In the present invention, an apparatus for implementing the abovementioned method is also provided.Type: GrantFiled: October 16, 2012Date of Patent: February 19, 2019Assignees: Mississippi International Water Inc.Inventor: Dawei Zhang

Publication number: 20140332362Abstract: The present invention discloses a destructive distillation apparatus, comprising a destructive distillation drum; a feeding drum and a discharge drum, respectively located at each of two ends of the destructive distillation drum. The destructive distillation drum has a larger diameter than the feeding drum and the discharge drum. An inner wall of the destructive distillation drum is installed with rows of tripper and guiding plates, and a spacing is kept between every two adjacent rows of the tripper and guiding plates. Each row of the tripper and guiding plates are consisted of a plurality of tripper and guiding plates, and each tripper and guiding plate is formed by a flat plane and a triangle having a slope. The flat planes of each row of the tripper and guiding plates are horizontally arranged, and a pointed end of the triangle is directed toward a discharge port of the destructive distillation drum. The destructive distillation drum is placed into a combustion chamber.Type: ApplicationFiled: September 14, 2012Publication date: November 13, 2014Applicants: MISSISSIPPI INTERNATIONAL WATER INC.Inventor: Dawei Zhang

Patent number: 8388902Abstract: A method for regenerating activated coke used for treating wastewater or sewage is provided. The method includes loading the activated coke to an environment under 150 to 250° C., heating the activated coke to a temperature of 700 to 850° C. for about 40 to 90 minutes; and providing a steam to the activated coke with a rate of 0.1 to 0.5 m3/(ton of activated coke). When the activated coke is being heated at the temperature, it generates a gas mixture including a steam portion and at least a paraffine gas. The gas mixture flows along a reverse direction relative to a flow of cooling water, so that the steam portion is converted into a part of the cooling water for recycling. The paraffine gas is used as a fuel. An apparatus for regenerating the activated coke used for treating wastewater or sewage is also provided.Type: GrantFiled: December 16, 2008Date of Patent: March 5, 2013Assignees: Dawei Zhang, Mississippi International Water, Inc.Inventor: Dawei Zhang
