X-ray high-temperature high-pressure catalytic reaction furnace

Abstract

The invention provides an X-ray high-temperature high-pressure catalytic reaction furnace including a gas inlet passage, a furnace upper cover, a furnace cavity, a base and a gas outlet passage, the gas inlet passage is communicated with the furnace cavity through a communication hole, the inner side of the furnace cavity is provided with a shielding layer, a window and a beryllium window flange are arranged on the outer wall of the furnace cavity, and a protective layer is arranged between the window and the beryllium window flange, the protective layer includes an aluminized beryllium sheet layer on the outer side and a polymer film layer on the inner side, and the shielding layer includes a beryllium sheet arranged correspondently to the protective layer. The beryllium window flange, the aluminized beryllium sheet layer, the polymer film layer, a rubber ring, the furnace cavity and the furnace upper cover are connected by bolts to form a seal cavity, the polymer film layer is arranged on the inner side of the aluminized beryllium sheet, and can isolate a catalytic gas and the aluminized beryllium sheet, so that the polymer film layer can protect the aluminized beryllium sheet from contamination by the catalytic gas and a catalytic material, an aluminized beryllium sheet material has excellent performances, can withstand a reaction pressure of 1MPa, and low energy X-ray can smoothly pass through and irradiate onto the catalytic material.

Description

technical field [0001] The invention relates to a catalytic furnace, in particular to an X-ray high-temperature and high-pressure catalytic reaction furnace. Background technique [0002] At present, most X-ray in-situ catalytic furnaces in China use polymer film materials as window materials, but due to the poor pressure and high temperature resistance of polymer film materials, X-ray catalytic reactors with polymer films as window materials can only To meet some requirements, the structure of the existing X-ray in-situ catalytic furnace is as follows image 3 As shown, the furnace loam cake 2, furnace cavity 1, sealing rubber ring 25, polymer film 26 and sealing flange 27 are connected into a sealed chamber by bolts. In the low-energy range, X-rays are easily absorbed by materials, resulting in the inability of rays to penetrate. Therefore, polymer film materials are used as window materials, but due to poor pressure and high temperature resistance of polymer materials (26...

Problems solved by technology

[0003] At present, in addition to polymer films, pure beryllium sheets plated with nano-scale Al layer can also be used as window materials, but beryllium sheets are expensive and beryllium oxide powder is a highly toxic substance. Pollution, resulting in impenetrability of X-rays, and severe accidents such as beryllium sheet rupture
