Patent number: 11014037Abstract: A membrane method processing system and process for a high-concentration salt-containing organic waste liquid incineration exhaust gas is described. The system consists essentially of a waste liquid incinerator (I), a gas-solid separator (II), a heat exchanger (III), an air blower (IV), an anti-caking agent storage tank (V), a membrane method dust cleaner (VI), an induced draft fan (VII), a check valve (VIII), and a desulfurization tower (IX). The present invention introduces the dust collecting membrane into the tail gas treatment system and utilizes the small pore size and high porosity of the dust collecting membrane to prevent inorganic salt particles from entering the internal of the filter material and agglomerating there. When the humidity of the gas entering the dust collector increases during the dust removing process, the anti-caking agent is also introduced into the tail gas treatment system to change the surface structure of the inorganic salt crystal to prevent the crystal from agglomeration.Type: GrantFiled: May 4, 2018Date of Patent: May 25, 2021Assignee: JIANGSU JIULANG HIGH-TECH CO., LTD.Inventors: Zhaoxiang Zhong, Feng Zhang, Junwei Wu

Patent number: 10875783Abstract: The present invention relaters to a method for continuously preparing a nano zinc oxide with a membrane reactor. A zinc salt solution and a precipitator solution required for the preparation of a zinc oxide are respectively used as dispersion phases, and under the action of a certain pressure, the two reaction solutions respectively penetrate through a membrane tube at a certain rate and disperse quickly under the action of a shear force and react, producing a precursor precipitate. A precursor suspension penetrates through the membrane tube continuously and circularly after being pressurized by a pump, and at the same time, deionized water as a washing fluid is added to a suspension storage tank, wherein impurity ions penetrate through membrane pores and are discharged along with the liquid medium; after the concentration of the impurity ions meets requirements, the concentrated solution is discharged continuously and then spray-dried to obtain a basic zinc carbonate precursor powder.Type: GrantFiled: September 12, 2014Date of Patent: December 29, 2020Assignee: NANJING UNIVERSITY OF TECHNOLOGYInventors: Weihong Xing, Zhilong Xu, Nanping Xu, Zhaoxiang Zhong, Feng Zhang
