Carbon/carbon composite material chemical vapor deposition (CVD) high-temperature tail gas condensing and filtering structure

Abstract

The invention relates to the field of filtering structures, in particular to a carbon / carbon composite material CVD high-temperature tail gas condensing and filtering structure. The filtering structure comprises a high-temperature condensing tank and a tar carbon black filtering tank, wherein a high-temperature tail gas inlet pipeline and a cooling water inlet pipeline are respectively arranged onthe tank body of the high-temperature condensing tank, an upper flange cover is arranged at the top end of the high-temperature condensing tank, a tar storage tank is arranged at the bottom end of the high-temperature condensing tank, a lower flange cover is arranged at an opening of the tar storage tank, and a cooling water circulating pipeline and a tail gas channel are fixed in the high-temperature condensing tank. A tail gas exhaust pipeline is arranged on the tank body of the tar carbon black filtering tank, a flange cover and a drain outlet are arranged at the upper end and the lower end of the tar carbon black filtering tank respectively, and a cooling water outlet pipeline and a filter element are arranged in the tar carbon black filtering tank. The structure is divided into a condensing part and a filtering part, each part is provided with an independent functional unit, and the filter element can be replaced periodically, so that the filtering effect is improved, the maintenance and removal operations become convenient, the labor intensity is greatly reduced, and the equipment utilization rate is increased.

Description

technical field [0001] The invention relates to the field of filter structures, in particular to a carbon / carbon composite chemical vapor deposition high-temperature tail gas condensation filter structure. Background technique [0002] With the continuous development of aerospace and military technology, higher requirements are placed on the performance of aircraft, and its service environment is becoming more and more severe. Therefore, higher requirements are placed on material performance. Many aircraft and their components need to work in high temperature and ultra-high temperature environment. Carbon / carbon (C / C) composite material, that is, carbon fiber reinforced carbon matrix composite material, is a material that can be used in ultra-high temperature environment. Its excellent Its high specific strength, thermal shock resistance, and ablation resistance are the most ideal candidate materials for space shuttle nose cones and solid rocket engine throat liners; its exc...
