  • Publication number: 20220227650
    Abstract: An integrated boron removal and flocculation process for treating fracturing wastewater is disclosed. The process comprises: adjusting the pH of the fracturing flowback liquid to be treated to become alkaline and adding thereto an oxidant to carry out a reaction for a certain time period, so that the state of the boron present in the liquid is changed; and then adding a barium salt to the resulting reaction mixture to carry out a further reaction between the barium salt and the boron in the changed state to produce a precipitate. The stability of the flowback liquid is deteriorated by the addition of the oxidant. Suspended solids in the flowback liquid can be removed through adsorption, wrapping, and then settling by the action of the precipitate (a barium salt). The process integrates boron removal and flocculation and enables a boron removal rate of 80% or greater. The contents of the suspended solids and oil present in the fracturing flowback liquid after filtration each can be lowered to less than 5.

  • Publication number: 20220222536
    Abstract: A trusted graph data node classification method includes: (1) inputting a topological graph and node features, and calculating a discrete Ricci curvature of the discrete topological graph; (2) preprocessing the curvature and the node features; (3) mapping the curvature, reconstructing original features, and performing a semi-supervised training on graph data containing adversarial examples; and (4) performing a classification on unlabeled nodes. The new method uses a discrete curvature to extract topological information, and uses a residual network to reconstruct node feature vectors without knowing the technical details of the adversarial examples, and without using a large number of adversarial examples for adversarial training. Hence, the system effectively defends against attacks from adversarial examples on the graph data, outperforms the existing mainstream models in terms of accuracy when used in data without adversarial examples, and is thus a trusted node classification system.

  • Patent number: 11371532
    Abstract: An inlet collector for a centrifugal fan and a centrifugal fan are provided. By arranging a tragus-shaped section in a guiding section, reverse flow caused by intersection of inlet leakage flow at a volute tongue side and inlet airflow is blocked by the tragus-shaped structure in movement process, and the leakage flow no longer collide with the inlet airflow. An inner curved surface of the tragus-shaped section controls backflow to change smoothly along an inner wall surface of the tragus-shaped section and re-enter a volute for circulation. A tragus profile is adopted to guide the airflow to change more smoothly in the velocity direction near the wall of the guiding section, so as to effectively reduce the impact of the inlet airflow on the guiding section. By using the inlet collector, energy loss of airflow is reduced, vortex formation is suppressed, and aerodynamic performance and fan noise are improved.
