This utility model discloses a gas distributor for a chloromethane synthesis reactor. The main support pipe and the main distribution pipe are arranged parallel to each other and positioned below the main distribution pipe. Distribution branch pipes are provided on the main distribution pipe, symmetrically arranged at a 45-degree angle to the horizontal line of the main distribution pipe. A supporting inclined pipe connects the distribution branch pipes to the main support pipe at a 90-degree angle. Both the main distribution pipe and the distribution branch pipes have three rows of distribution holes, arranged on the lower side of the main distribution pipe and the distribution branch pipes. Two rows are symmetrically arranged at a 45-degree angle to the horizontal line of the main distribution pipe and the distribution branch pipes, and one row is arranged at a 90-degree angle to the horizontal line of the main distribution pipe and the distribution branch pipes. This utility model's gas distributor device has a simple structure, uniform stress on the distribution pipes, and a firm connection. It requires fewer pipe openings at the bottom of the equipment, reducing the risk of material leakage. The steel-lined support rods with a double-layer anti-corrosion design have strong corrosion resistance, extending the service life of components and the equipment maintenance cycle.
