Description

Technical Field

[0001] This utility model belongs to the technical field of chemical mass transfer equipment components, and particularly relates to an anti-clogging constant pressure distributor. Background Technology

[0002] The liquid distributor is a core internal component of packed towers, belonging to the category of chemical mass transfer equipment. It is mainly used in atmospheric pressure, pressurized, and vacuum operating environments in processes such as distillation, absorption, and extraction. This distributor improves the mass transfer efficiency of the packing by uniformly distributing the liquid, reducing liquid channeling and wall flow, increasing tower efficiency, and thus reducing tower construction costs.

[0003] The existing technology uses a tray-type distributor. This distributor distributes liquid to different outlets through spray holes on the riser tank, achieving liquid distribution and regulation. However, during use, solid particles, deposits, scale, and other factors can cause blockages in the tray-type distributor, leading to uneven gas-liquid distribution and reduced mass transfer efficiency. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing an anti-clogging constant pressure distributor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-clogging constant pressure distributor includes a base plate, on which several air cylinders are fixed. The top of each air cylinder is connected to a liquid collection tank. An air trough is connected between the air cylinders and the liquid collection tank. The cross-sectional area of ​​the air trough gradually decreases from the air cylinders toward the liquid collection tank. Several spray holes are provided on the air trough, and the width of the top of each spray hole is greater than the width of the bottom.

[0007] In the aforementioned anti-clogging constant pressure distributor, the air riser includes two inclined plates. One end of the plate is sealed to the liquid collection tank, and the other end is sealed to the top of the air riser. Spray holes are located on the plate.

[0008] In the aforementioned anti-clogging constant pressure distributor, the included angle between the trough plate and the air riser is an obtuse angle.

[0009] In the aforementioned anti-clogging constant pressure distributor, the included angle between the trough plate and the air riser is between 145° and 175°.

[0010] In the aforementioned anti-clogging constant pressure distributor, the spray holes are evenly distributed on the trough plate.

[0011] In the aforementioned anti-clogging constant pressure distributor, the spray holes on each trough plate are at the same height in the horizontal direction.

[0012] In the aforementioned anti-clogging constant pressure distributor, the spray holes are in the shape of an inverted convex character.

[0013] In the aforementioned anti-clogging constant pressure distributor, the spray holes include interconnected large holes and small holes, with the large holes located above the small holes.

[0014] In the aforementioned anti-clogging constant pressure distributor, the bottoms of the large and small holes are respectively arc-shaped, and the lengths of the large and small holes are the same.

[0015] In the aforementioned anti-clogging constant pressure distributor, the bottom of the liquid collection tank is connected to the tank plate via a support plate. The cross-section of the liquid collection tank is V-shaped, and both sides of the liquid collection tank extend beyond the support plate.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1) The inclined design of the gas riser creates an angle between the gas flow direction and the liquid overflow direction, reducing direct impact, thereby reducing entrainment rate and improving separation efficiency.

[0018] 2) The obliquely shaped inverted convex hole guides the liquid flow and reduces gas-liquid interference.

[0019] 3) The obliquely opened inverted convex holes enhance liquid flow and solid sedimentation, making them less prone to clogging.

[0020] 4) The inverted convex hole has a larger opening, making it easier for solid particles, deposits or scale to be discharged, which can effectively prevent the distributor from becoming clogged. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-3As shown, an anti-clogging constant pressure distributor includes a base plate 1, on which several air cylinders 2 are fixed. The top of the air cylinders 2 is connected to a liquid collection tank 3. An air trough 4 is connected between the air cylinders 2 and the liquid collection tank 3. The cross-sectional area of ​​the air trough 4 gradually decreases from the air cylinders 2 to the liquid collection tank 3. Several spray holes 5 are provided on the air trough 4. The width of the top of the spray hole 5 is greater than the width of the bottom.

[0027] Specifically, the air-lift tank 4 includes two inclined plates 6. One end of the plate 6 is sealed to the liquid collection tank 3, and the other end is sealed to the top of the air-lift cylinder 2. Spray holes 5 are located on the plates 6. By opening spray holes 5 on the inclined plates 6, the spray holes 5 are also inclined. The inclined holes can guide the liquid flow and reduce gas-liquid interference. On the other hand, the width of the top of the spray hole 5 is greater than the width of the bottom, which can adapt to changes in flow rate, maintain constant pressure, and make the liquid evenly distributed.

[0028] In addition, the inclined arrangement of the trough plate 6 guides the gas to diffuse more evenly along the tower cross section, guides the liquid flow direction, reduces gas-liquid interference, and improves mass transfer efficiency.

[0029] In this embodiment, combined with Figure 3 As shown, the spray nozzle 5 is in the shape of an inverted U-shape. Specifically, the spray nozzle 5 includes a large hole 7 and a small hole 8 connected to each other, with the large hole 7 located above the small hole 8. This inverted U-shaped spray nozzle 5, on the one hand, has a large diameter, and on the other hand, is inclined, which can effectively prevent clogging.

[0030] The bottoms of the large hole 7 and the small hole 8 are both arc-shaped, and the lengths of the large hole 7 and the small hole 8 are the same. The arc-shaped bottoms serve to guide the flow of liquid.

[0031] like Figure 2 As shown, the included angle α between the trough plate 6 and the air lifting cylinder 2 is an obtuse angle. Specifically, the included angle between the trough plate 6 and the air lifting cylinder 2 is between 145° and 175°. At this angle, the trough plate 6 and the air lifting trough 4 form a triangular support, maintaining structural stability.

[0032] The spray holes 5 are evenly distributed on the trough plate 6. The gauges for the spray holes 5 can be adjusted and determined according to the actual working conditions, which is a common adjustment in this field and is not limited in this application.

[0033] It should be noted that the spray holes 5 on each tank plate 6 are at the same height in the horizontal direction. Here, each tank plate 6 can be understood as having the same height for all the spray holes 5. In this way, when the liquid level reaches a certain height, all the spray holes will contact the liquid surface at the same time and perform spraying operations simultaneously, thus making the spraying uniform.

[0034] The bottom of the liquid collection tank 3 is connected to the tank plate 6 via the support plate 9. The cross-section of the liquid collection tank 3 is V-shaped, and both sides of the liquid collection tank 3 extend out of the support plate 9.

[0035] This utility model's distributor adopts a vertical design with an inclined trough plate in the middle, guiding gas to diffuse more evenly along the tower cross-section and directing liquid flow, reducing gas-liquid interference and improving mass transfer efficiency. The inverted convex holes on the trough plate serve two purposes: firstly, the inclined holes guide liquid flow, reduce gas-liquid interference, improve liquid gravity flow and solid settling performance, and enhance mass transfer efficiency; secondly, the inverted convex holes are larger than those in existing trough-type distributors, allowing solid particles, deposits, or scale to be discharged more easily, effectively preventing distributor clogging.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.
