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. Including the dust removal mechanism, the dust removal mechanism is provided with an air inlet end and an air outlet end, the air inlet end of the dust removal mechanism is fixedly connected with a particle filter mechanism, the air outlet end of the dust removal mechanism is fixedly connected with an outlet pipe, and the other end of the outlet pipe is fixed A shunt pipe is connected, the other end of the shunt pipe is fixedly connected with a flue gas condensing mechanism, and the side of the flue gas condensing mechanism is fixedly connected with a cooling tower through a cooling pipe. The present invention utilizes the cone-shaped filter cover inside the particle filter mechanism to directly block the large particle size from the air and recycle the large particle size dust into the recovery box through the dust guide pipe and the recovery cover, and then the micro dust contained in the flue gas will be When reaching the micro-dust removal mechanism, the micro-dust contained in the flue gas is greatly reduced, avoiding the occurrence of subsequent pipeline blockage caused by micro-dust during long-term use.

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
