This application relates to a backwashing system and an automatic backwashing filter device. The backwashing system includes a first backwashing pipeline for conveying a first backwashing medium, connected to the backwashing inlet of the filter; a second backwashing pipeline for conveying a second backwashing medium, also connected to the backwashing inlet of the filter; and a controller for controlling the first and second backwashing pipelines to perform a backwashing process. The backwashing process includes at least one draining process, which involves controlling the input of the first backwashing medium into the first backwashing pipeline to drain the second backwashing medium. The first backwashing medium and the working medium are in a neutral relationship, while the second backwashing medium and the working medium are in an interfering relationship. The backwashing system of this application improves the problem of interference between the backwashing medium and the working medium in existing technologies.

The invention relates to a multifunctional multi-physical field combustion chamber outlet measuring device, and belongs to the technical field of aero-engine combustion chambers. The device comprises a measurement section casing and multiple types of measurement assemblies installed on the measurement section casing. The measuring section casing adopts a collaborative partition structure of an equal straight section and a sudden expansion section, the equal straight section is provided with a static pressure / dynamic pressure guide assembly, a TDLAS assembly and a high-frequency thermocouple in a focusing manner, and the sudden expansion section is provided with a fixed composite rake assembly or a movable multi-point thermocouple rake assembly through a switchable process window. The detection end of each component corresponds to the same measurement area in the equal straight section, so that the pressure, temperature distribution, component concentration and transient pulsation information of the outlet of the combustion chamber can be synchronously obtained in the same area in a single test. According to the method, the problems of layout conflict and data space-time inconsistency when a multi-heterogeneous measurement technology is integrated are solved, the method has the capabilities of steady-state field surveying and mapping and dynamic process capturing, data cross verification can be realized in a contact and non-contact measurement mode, and the measurement efficiency, the data quality and the system reliability are remarkably improved.
