Description

technical field [0001] The invention relates to the field of gas heating flow control devices, in particular to a gas heating flow control device for carbon nanotube production. Background technique [0002] Carbon nanotubes, also known as bucky tubes, are one-dimensional quantum materials with a special structure (the radial dimension is in the order of nanometers, the axial dimension is in the order of micrometers, and both ends of the tube are basically sealed). Carbon nanotubes are mainly composed of several to dozens of layers of coaxial circular tubes of carbon atoms arranged in a hexagonal shape. A fixed distance is maintained between the layers, about 0.34 nm, and the diameter is generally 2-20 nm. And according to the different orientations of the carbon hexagon along the axial direction, it can be divided into three types: zigzag, armchair and spiral. The helical carbon nanotubes have chirality, while the zigzag and armchair carbon nanotubes have no chirality. C...

Problems solved by technology

When carbon nanotubes are produced, raw material gas needs to be input, and the raw material gas is a mixed gas composed of various gases. The existing gas heating flow control device lacks a mixing process for the mixed gas, which reduces the production efficiency of carbon nanotubes; therefore , presenting a gas heating flow control device for carbon nanotube production
