Description

Multilayer annular cone type gas distributor Technical Field The utility model relates to the technical field of gas distributors, in particular to a multi-layer annular cone type gas distributor. Background In industrial production, conventional gas distributors have significant drawbacks in gas flow rate control and distribution uniformity. The common gas distributor adopts a single barrel structure, the speed change is severe when the gas flows through, and vortex and local high-speed areas are easy to generate, so that the gas distribution is uneven, and the reaction efficiency and the product quality are affected. Such uneven gas distribution may also cause localized overheating or wear of the equipment, shortening the service life of the equipment. In addition, in attempts to build up a multi-layer structure, the gas transition from layer to layer is not smooth enough, which tends to cause sudden changes in pressure loss and flow velocity when the gas flows between layers, further affecting the stability and uniformity of the gas distribution. Disclosure of utility model The utility model aims to solve the technical problem of providing a gas distributor which can realize stable transition of gas flow velocity, is uniformly distributed and has a reasonable structure. The multi-layer annular cone type gas distributor is characterized in that the annular cone cylinders are arranged in a concentric nested mode, a multi-layer nested annular cone structure is formed by sequentially expanding from the middle to the outer side, support rods are fixedly arranged in the annular cone cylinders, the annular cone cylinders are fixedly connected in a matched mode through the support rods, and a gas inlet and a gas outlet are arranged in the annular cone cylinders. According to a further technical scheme, the two support rods are arranged and are respectively arranged in the gas inlet and the gas outlet of the annular cone.
