Abstract: An anti-oxidation dipping treatment method for a graphite sealing element for a thermal power generation unit, and an anti-oxidation production line. The anti-oxidation dipping treatment method for a graphite sealing element for a thermal power generation unit comprises the following steps: S1, placing a graphite sheet into a soaking device for soaking; S2, conveying the soaked graphite sheet into a drying and curing device for drying and curing; S3, stacking the multiple dried and cured graphite sheets together, and subjecting same to compression molding to form a layered graphite body; and S4, stamping the layered graphite body to form a finished graphite sealing element with a desired appearance.

Abstract: This application relates to the technical field of coal-fired boilers, and provides a method and an apparatus for improving steam oxidation resistance of a small-diameter boiler tube in a coal-fired boiler. The method includes the following steps: cutting a boiler tube panel from a ceiling of the boiler, vertically hoisting and fixing the boiler tube panel, and cutting out a section from a bottom portion of a lower bend of the boiler tube panel; cleaning an inner tube wall of each tube body in the boiler tube panel; performing oxidation resistance coating sintering on the inner tube wall of each tube body in the boiler tube panel; and performing a welding repair on each tube body in a sintered boiler tube panel. All construction processes of this method can be completed in a furnace during shutdown and maintenance, production efficiency is high, and maintenance duration can be significantly reduced.

Abstract: The pure mechanical well deviation wireless measure-while-drilling and mud pulse generation device includes an outer cylinder and an inner cylinder coaxially arranged inside the outer cylinder; an inner flow channel is formed inside the inner cylinder, and an outer flow channel is formed between the inner cylinder and the outer cylinder; a flow control valve and a hydraulic turbine are arranged in the inner flow channel, and the flow control valve is located at an upstream section of the hydraulic turbine. The device further includes a signal generation base and a rotary stopper. An overflow hole is formed on the signal generation base and arranged in the annular outer flow channel, and the rotary stopper can periodically shield the overflow hole. The inclinometer includes the pure mechanical well deviation wireless measure-while-drilling and mud pulse generation device, an inclinometer outer cylinder and an eccentric rotary column.

Abstract: Embodiments of the present application provide a method and system for task processing. During operation, the system may receive a task event generated by a task sending device with an initial state of the task event being a to-be-accepted state. The system may perform a first reminding operation associated with the task event for a user. Upon receiving a predetermined user response, the system may change the state of the task event from the to-be-accepted state to an activated state, wherein the predetermined user response is responsive to the first reminding operation associated with the task event.
