Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas distributor technology, specifically a multi-layer annular cone gas distributor. Background Technology
[0002] In industrial production, traditional gas distributors have significant shortcomings in terms of gas flow rate control and distribution uniformity.
[0003] Common gas distributors employ a single cylindrical structure, resulting in drastic velocity changes as gas flows through them. This can easily generate eddies and localized high-speed zones, leading to uneven gas distribution and impacting reaction efficiency and product quality. Such uneven gas distribution can also cause localized overheating or wear, shortening the equipment's lifespan.
[0004] Furthermore, in attempts at multi-layer structures, the gas transition between layers is not smooth enough, which can easily cause pressure loss and sudden changes in flow velocity when the gas flows between layers, further affecting the stability and uniformity of gas distribution. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a gas distributor that can achieve a smooth transition of gas flow rate, uniform distribution and reasonable structure.
[0006] This utility model is achieved through the following technical solution: A multi-layer annular cone gas distributor of this utility model includes multiple annular cones, characterized in that the multiple annular cones are concentrically nested and expand sequentially from the middle to the outside to form a multi-layer nested annular cone structure. A support rod is fixedly installed in each annular cone, and the support rod fixes and connects the annular cones. A gas inlet and a gas outlet are provided in each annular cone.
[0007] In a further technical solution, two support rods are provided, and they are respectively installed in the gas inlet and gas outlet of the annular cone.
[0008] In a further technical solution, the annular cone includes a rapid stabilization section, a rapid to slow diffusion section, and a slow to stable diffusion section.
[0009] In a further technical solution, the spacing between the fast stabilization sections of the multiple annular cones is the same, the spacing between the fast to slow diffusion sections of the multiple annular cones gradually increases from the outside to the inside, and the spacing between the slow to stable diffusion sections of the multiple annular cones is the same.
[0010] A further technical solution includes a fast stabilization section comprising an inlet straight edge, a fast to slow diffusion section comprising an inlet spiral edge and an annular cone, and a slow to stabilization section comprising an outlet spiral edge and an outlet straight edge. The inlet spiral edge is fixedly disposed to the right of the inlet straight edge, the annular cone is fixedly disposed to the right of the inlet spiral edge, the outlet spiral edge is fixedly disposed to the right of the annular cone, and the outlet straight edge is fixedly disposed to the right of the outlet spiral edge.
[0011] A further technical solution involves increasing the length of the straight edge of the inlet in the annular cone from the outside in.
[0012] A further technical solution involves decreasing the length of the inlet spiral edge in the annular cone from the outside in.
[0013] A further technical solution involves decreasing the opening width of the annular cone in the annular cone cylinder from the outside in.
[0014] A further technical solution involves gradually transitioning the outlet spiral edge of the annular cone from an arc state to a horizontal state from the outside to the inside.
[0015] In a further technical solution, the straight edge of the outlet is horizontal.
[0016] The beneficial effects of this utility model are as follows: First, by adopting a multi-layered nested annular cone, the annular cone, the inlet spiral edge, and the outlet spiral edge more effectively facilitate the transition of gas flow rate changes, making the gas change more stable. The annular cone shape makes the gas diffusion more uniform and the pressure very low, making the gas flow rate more suitable for the next working condition.
[0017] II. The annular cone includes a rapid stabilization section, a rapid to slow diffusion section, and a slow to steady diffusion section, which can achieve rapid stabilization, fast to slow stable diffusion, and slow to steady diffusion of gas, and can effectively reduce the gas flow rate.
[0018] III. The specific structural dimensions of the inlet straight edge, inlet spiral edge, annular cone, outlet spiral edge, and outlet straight edge are designed to ensure that the spacing between the fast stabilization sections of the multiple annular cones is the same, the spacing between the fast to slow diffusion sections of the multiple annular cones gradually increases from the outside to the inside, and the spacing between the slow to stable diffusion sections of the multiple annular cones is the same, forming multiple functional spaces to achieve the corresponding deceleration and stabilization functions.

For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The projection relationship of the multi-layer annular cone gas distributor is consistent in the up, down, left, right, front and back directions. The multi-layer annular cone gas distributor includes multiple annular cones, which are concentrically nested and expand from the middle to the outside to form a multi-layer nested annular cone structure. A support rod 18 is fixedly installed in the annular cone, and the support rod 18 fixes and connects the annular cone. A gas inlet 11 and a gas outlet 17 are provided in the annular cone.
[0025] Advantageously, the material of the annular cone can be a corrosion-resistant and rust-proof material, such as stainless steel.
[0026] Advantageously, when fixing the support rod 18, a through hole can be provided in the annular cone cylinder so that the support rod 18 passes through the through hole and is snapped in place.

[0035] Beneficially, the straight edge 16 at the outlet is in a horizontal position.
[0036] Gas enters through gas inlet 11, first passing through the straight edge of inlet 12 for rapid and stable entry, and then passing through the spiral edge of inlet 13 and the annular cone 14, at which point the gas flow rate gradually decreases and diffuses steadily.
[0037] When the gas passes through the outlet spiral edge 15 and the outlet straight edge 16, the gas flow rate gradually decreases from slow to steady and diffuses evenly from the gas outlet 17 into the inside of the right-side equipment cylinder.
