Furthermore, the limiting groove is positioned between the adjacent atomizing nozzles. The arrangement is convenient for the installation of the atomizing spray head.
Furthermore, the top of the distribution pipe is provided with a flow deflector along the circumference of the annular body, and the flow deflector is obliquely arranged towards the inside of the annular body. Set up like this and reduce the residue of tetrachlorosilane on the distribution pipe, lead the middle part of tetrachlorosilane ring body through the water conservancy diversion piece simultaneously to carry out abundant contact reaction with atomizing ethanol.
Furthermore, a transition pipe is communicated between the head end and the tail end of the distribution pipe, and a one-way valve is arranged on the transition pipe. Because the tail end of the distribution pipe is arranged in a closed manner, part of ethanol solution is collected at the tail end of the distribution pipe, and the pressure at the tail end cannot be released, the arrangement of the transition pipe can guide the collected ethanol into the head end of the distribution pipe to release the pressure at the tail end, and meanwhile, the arrangement of the one-way valve can prevent the ethanol pumped from the outside from directly entering the tail end of the distribution pipe.
