Chemical vapor infiltration process and device
The invention provides a chemical vapor infiltration process and device. The chemical vapor infiltration device comprises a furnace body (1), a stacking table and an isolation cylinder (5) are arranged in the furnace body, the bottom end of the isolation cylinder is connected with the upper surface of the stacking table in a sealed mode, a gas collecting hood (9) is arranged at the top end of the isolation cylinder, and the gas collecting hood is connected with the isolation cylinder in a sealed mode. The top of the gas collecting hood extends to the joint of the furnace body and a tail gas pipeline (10), a gas outlet opposite to the tail gas pipeline is formed in the gas collecting hood, a vent hole (2) is formed in the area, located in the isolation barrel, of the stacking table, a pressing box used for being stacked on a workpiece (4) is arranged in the isolation barrel, and a waste gas adsorbing material (8) of a porous structure is contained in the pressing box. And air holes are formed in the pressing box. By adopting the chemical vapor infiltration device provided by the invention, a hearth of the CVI furnace can be effectively prevented from being polluted, and a tail gas pipeline is prevented from being blocked.
本发明提供了一种化学气相渗透工艺及装置，化学气相渗透装置包括炉体(1)，炉体内设置有堆料台和隔离筒(5)，隔离筒的底端与堆料台的上表面密封连接，隔离筒的顶端设置有集气罩(9)，集气罩与隔离筒密封连接，集气罩的顶部延伸至炉体与尾气管道(10)的连接处，集气罩开设有与尾气管道相对的出气口，堆料台的位于隔离筒内的区域内开设有通气孔(2)，隔离筒内设置有用于堆放在工件(4)上的压料盒，压料盒内装有多孔结构的废气吸附材料(8)，压料盒开设有透气孔。采用本发明提供的化学气相渗透装置，可有效避免污染CVI炉的炉膛及避免堵塞尾气管道。
