Carbon-carbon composite material chemical vapor deposition tail gas condensation treatment device

Abstract

The invention discloses a carbon-carbon composite material chemical vapor deposition tail gas condensation treatment device, and relates to the technical field of tail gas treatment equipment. The device comprises a tiny dust removing mechanism, wherein the tiny dust removing mechanism is provided with a gas inlet end and a gas outlet end, the gas inlet end of the tiny dust removing mechanism is fixedly connected with a particle filtering mechanism, the gas outlet end of the tiny dust removing mechanism is fixedly connected with a leading-out pipe, the other end of the leading-out pipe is fixedly connected with a flow dividing pipe, the other end of the flow dividing pipe is fixedly connected with a smoke condensation mechanism, and the side surface of the smoke condensation mechanism is fixedly connected with a cooling tower through a cooling pipe. According to the invention, large-particle-size dust is directly blocked and discharged through a conical filter cover in the particle filtering mechanism, large-particle-size dust is recycled into a recycling box through a dust guide pipe and a recycling cover, and then tiny dust contained in flue gas can reach the tiny dust removing mechanism, so that the tiny dust contained in the flue gas is greatly reduced, and the phenomenon that a subsequent pipeline is blocked due to tiny dust in long-term use is avoided.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment equipment, in particular to a carbon-carbon composite material chemical vapor deposition tail gas condensation treatment device. Background technique [0002] Carbon-carbon composites are carbon matrix composites reinforced by carbon fibers and their fabrics. It has the advantages of low density, high strength, high specific modulus, high thermal conductivity, low expansion coefficient, good friction performance, good thermal shock resistance, and high dimensional stability. It is one of the few candidate materials used above 1650 °C today. The highest theoretical temperature is as high as 2600°C, so it is considered to be one of the most promising high-temperature materials. During the production process, it is purified by chemical vapor deposition. This technology mainly uses one or several gas phases containing thin film elements. Compound or simple substance, the method of chemical...

Problems solved by technology

[0004] The above patents also have the following problems: 1. The cyclone dust collector used cannot remove the small particles of dust. During the long-term use of the tail gas condenser, the accumulation of small particles of dust will cause the pipeline of the condenser to be blocked, resulting in exhaust gas The reduction of processing efficiency; 2. The cooling method adopted is graphite tube group, which is not equipped with active heat dissipation device. During the continuous cooling process of graphite tube group, its temperature will rise rapidly, resulting in the loss of cooling capacity of graphite tube group
