The invention discloses ultrasonic coupling electrochemical coagulation phosphorus-contained wastewater treating method and device. In the method, the phosphorus-contained wastewater of a wastewater storing tank is conveyed into a reaction tank; a power supply supplies power for a positive electrode and a negative electrode in an electrode unit, and the positive electrode generates a metal ion; and an ultrasonic wave generated by an ultrasonic generator directly acts on the phosphorus-contained wastewater in the reaction tank by the wall vibration of the reaction tank and is matched with the high-valence state metal ion to realize the coagulated purification of the phosphorus-contained wastewater. The device comprises the ultrasonic generator, the reaction tank, the power supply, the wastewater storing tank, a water discharge container, a flowmeter and a circulating pump. The invention has high reaction speed, high processing efficiency and low energy consumption.

A spacer (1) for a battery, said spacer comprising a frame (11), a wall (12) and at least one protruding element (13), wherein the wall (12) is disposed at least partially within the frame (11) and wherein the protruding element (13) is disposed on at least one side of the wall (12) and protrudes from the same. Recesses are thereby provided on at least two sides (111, 112) of the frame (11), whereby a fluid can flow along the wall (12) through the frame (11).

The invention relates to an iron removal device for removing iron scrap or steel scrap in a material. The iron removal device which has a reliable iron removal effect and is convenient to use comprises magnets, wherein the magnets are tubular or uniformly arranged along the tube wall of a tube body, so that the tubular magnets or the tube body can be directly arranged in a material circulation area, and the material can flow through the tube body by any prior art; the magnets are tubular or uniformly distributed along the tube wall of the tube body, so a complete annular adsorption magnetic field can be formed for the iron scrap or the steel scrap in the flowing material, a reliable adsorption effect is achieved, and the iron removal effect is ensured; meanwhile, the tubular magnets or the tube body on which the magnets are arranged along the tube wall can be conveniently arranged and used.

The invention discloses a long-time high-temperature wind tunnel test cabin. A cabin wall of the test cabin comprises an inner wall and an outer wall, wherein the inner wall is connected with the outer wall through a partition to form a water-cooled channel; and cooling water is fed into the water-cooled channel. The problem of long-time thermal protection of the wind tunnel test cabin in a severe hot environment is solved.

The invention discloses a flow-in control valve which consists of a valve seat, a lower valve body, a valve core and an upper valve body, wherein the valve seat is mounted on a production pipeline; a steplike hole is formed in the valve seat; the lower valve body is embedded into the steplike hole of the valve seat; the axial position is limited by a boss; a conical hole is formed in the lower valve body; a circular hole is formed in the upper part of the upper valve body, and a curved hole is formed in the lower part of the upper valve body; the upper valve body is screwed on the valve seat in a threaded connection manner; the valve core is arranged in a space formed by the conical hole of the lower valve body and the curved hole of the upper valve body; the valve core is an entity consisting of a valve core lower conical surface, a valve core upper curved surface and valve core lower runners; the slope of the valve core lower conical surface is greater than that of the conical hole of the valve body; and the valve core lower runners are long-strip slots uniformly formed in the lower end of the valve core lower conical surface. The flow-in control valve can automatically adjust the size of a runner space of the valve according to the type of fluid and components of the fluid in a hydrocarbon reservoir, increase the flow-in amount of oil, control flow-in of water and gas and prevent water layer penetration and gas layer penetration, so that the yield and the quality of an oil product can be effectively controlled.

The invention discloses a chemical vapor deposition device which comprises a reaction chamber and a gas inlet device. A substrate tray and a rotary shaft are arranged in the reaction chamber, the substrate tray is used for supporting a plurality of substrates, the gas inlet device is arranged above a substrate bearing device and used for providing reaction gas flowing to the surfaces of the substrates, and a reaction area is formed between the gas inlet device and the substrate bearing device. A central exhaust system is arranged in the center area of the substrate bearing device. An annular edge exhaust system is arranged around the substrate bearing device. The reaction gas and side reaction gas on the surface of each substrate are exhausted out of the reaction chamber through the central exhaust system and the edge exhaust system at the same time. The thin film deposition yield and uniformity of the surfaces of the substrates can be effectively adjusted.
