Description

Technical Field

[0001] This utility model relates to the field of vapor-liquid distributor technology, specifically a multi-stage vapor-liquid distributor. Background Technology

[0002] Distillation columns are key equipment in chemical, petroleum refining, and other fields used to separate liquid mixtures. Separation is achieved by utilizing the differences in volatility of the components in the mixture. After passing through multiple layers of packing in the distillation column, a collector is needed to collect the liquid phase from different trays or packing sections for further separation. Vapor-liquid distributors are crucial equipment in chemical processes for achieving uniform gas-liquid distribution. However, traditional vapor-liquid distributors mostly employ a single-layer structure, resulting in limited liquid distribution point density. Under high-load conditions, this can easily lead to localized excessive or insufficient liquid volume, resulting in insufficient gas-liquid contact. Furthermore, to achieve uniform distribution, single-layer structures may increase pore density or the number of layers, leading to increased resistance to gas flow. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-7 As shown, this utility model is a multi-stage vapor-liquid distributor, including a liquid outlet channel 1. Multiple angular support bars 2 are fixedly connected to the inner bottom wall of the liquid outlet channel 1. Annular guide plates 3 and multiple vertical guide channels 4 are fixedly connected between the multiple angular support bars 2. Multiple long support bars 5 are fixedly connected to the surface of each of the multiple vertical guide channels 4. Reinforcing connecting bars 6 are fixedly connected between each two adjacent vertical guide channels 4. V-shaped guide connecting bars 7 are fixedly connected between each four adjacent long support bars 5. By setting multiple V-shaped guide connecting bars 7, the vapor and liquid are caught and initially guided, allowing the liquid to be guided by multiple V-shaped guide connecting bars 7 to be collected in the annular guide plate 3.

[0023] Multiple flow-guiding filter holes 8 are provided through the flow-guiding discharge tank 1. Multiple uniform discharge pipes 9 are fixedly connected to the bottom of the flow-guiding discharge tank 1. An L-shaped support frame 10 is fixedly connected to the surface of the flow-guiding discharge tank 1. The liquid is guided twice by the multiple flow-guiding filter holes 8 and then discharged from the multiple uniform discharge pipes 9. The liquid is distributed more evenly by being guided out through multiple holes.

[0024] Multiple angular support bars 2 are all the same height and are arranged in a ring array on the inner bottom wall of the liquid guide tank 1. The liquid guide tank 1 not only plays a collecting role, but also a guiding role.

[0025] The length of the two left and right V-shaped flow guide strips 7 is smaller than the length of the multiple V-shaped flow guide strips 7 in the middle. The multiple V-shaped flow guide strips 7 are arranged in a linear array between the tops of the multiple long support strips 5.

[0026] Multiple flow-guiding filter holes 8 and multiple uniform liquid outlet conduits 9 are arranged in a ring array on the flow-guiding liquid outlet tank 1. The multiple flow-guiding filter holes 8 are connected to adjacent uniform liquid outlet conduits 9 respectively. The liquid is evenly discharged by the multiple uniformly distributed flow-guiding filter holes 8 to their respective adjacent liquid outlet conduits 9 and flows out.

[0027] Two L-shaped support frames 10 are provided and are symmetrically distributed on the surface of the liquid outlet tank 1. The design of the two L-shaped support frames 10 can ensure the stability of the entire device when it is erected alone.

[0028] Distillation columns, as indispensable key equipment in core industrial fields such as chemical engineering and petroleum refining, bear the important mission of efficiently separating liquid mixtures. Their working principle is based on the significant differences in the volatility of the components in the mixture. By heating, the mixture is partially vaporized. Then, utilizing the different distribution coefficients of different components between the vapor and liquid phases, multiple cycles of partial vaporization and partial condensation are achieved within the distillation column, thereby gradually separating the components. Inside the distillation column, multiple layers of packing or trays constitute a complex and orderly separation space. The liquid mixture enters from the top or a certain position in the column and flows downwards layer by layer along the surface of the packing or trays, simultaneously coming into countercurrent contact with the vapor rising from the bottom. In this process, components with higher volatility more easily enter the gas phase, while components with lower volatility tend to remain in the liquid phase. Through repeated action of multiple layers of packing or trays, the components gradually form a concentration gradient within the column, ultimately yielding high-purity light and heavy components at the top and bottom of the column, respectively. However, achieving efficient and stable operation of a distillation column requires not only a reasonable internal structure and operating conditions but also the support of key auxiliary equipment. Among these, the collector is indispensable. Located after the multiple layers of packing or trays in the distillation column, it is responsible for collecting liquid products from different trays or packing sections. These liquid products may contain multiple components with varying concentrations. Through clever design, the collector can orderly gather these liquid products, facilitating further separation and processing. Meanwhile, the vapor-liquid distributor also plays a crucial role in chemical processes. It can uniformly distribute the gas and liquid phases entering the distillation column, ensuring that each layer of packing or tray fully contacts the gas-liquid mixture, thereby improving mass transfer efficiency and guaranteeing the separation effect of the distillation column. The performance of the vapor-liquid distributor directly affects the overall operating efficiency and product quality of the distillation column. Therefore, extra care must be taken in its design and selection. Parts not covered in this device are the same as or can be implemented using existing technologies.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] The working principle of this utility model is as follows: First, most of the liquid falls onto multiple V-shaped guide strips 7, and then the liquid is guided by the multiple V-shaped guide strips 7 and flows into the liquid outlet tank 1. The liquid that does not fall onto the V-shaped guide strips 7 passes through the long support strip 5 and multiple openings on the annular guide plate 3 and also falls into the liquid outlet tank 1. At this time, all the liquid is guided and concentrated on the liquid outlet tank 1 for preliminary unified collection and guidance, so that the liquid is concentrated. Then the liquid flows down evenly along the multiple guide filter holes 8 on the liquid outlet tank 1, and then is filtered down evenly through multiple uniform liquid outlet pipes 9 and discharged, for a second guidance, so that its distribution is more uniform.
