Description

Technical Field

[0001] This invention relates to the field of floating valve tray technology, and more particularly to a floating valve tray that provides sufficient gas-liquid contact. Background Technology

[0002] Valve trays have valve holes of a certain shape (circular or rectangular) with floating valve plates (circular, rectangular, disc-shaped, etc.) installed in them, forming different types of valve trays. Valve trays have become the most widely used type of tray due to their excellent comprehensive performance (high production capacity, high operational flexibility, high tray efficiency, and low manufacturing cost). However, in general valve trays, the rapid rise and fall of the tray can prevent the gas and liquid from fully mixing and contacting.

[0003] In existing technologies, the surface of the tray is usually a simple planar structure, which lacks the ability to guide and redistribute the liquid flow. This results in a short residence time of the liquid on the tray, and the gas mainly rises vertically from the bottom of the float valve into the liquid layer. The flow field of gas-liquid contact is relatively simple. When the rising gas velocity is too fast, the tray height is uniform, the space used for gas-liquid exchange is limited, and the gas-liquid exchange efficiency is low. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the surface of the tray is usually a simple planar structure, lacking the ability to guide and redistribute liquid flow, and the gas mainly rises vertically from the bottom of the float valve into the liquid layer, resulting in a relatively simple gas-liquid contact flow field. Therefore, this invention proposes a float valve tray with sufficient gas-liquid contact.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design a floating valve tray with sufficient gas-liquid contact, including a fixed frame. A first tray is installed at the bottom of the fixed frame, and the first tray is provided with several second guide holes. A second tray is installed at the top of the fixed frame, and several protrusions are provided at the top of the second tray. Several floating valve assemblies are evenly arranged on the top of the protrusions, and the floating valve assemblies extend above the top of the first tray. A conical groove is opened at the bottom of the second tray, and a blocking block is provided in the middle of the conical groove. The two sides of the blocking block are aligned with the bottom edges of the floating valve assemblies.

[0006] Preferably, the float valve assembly includes through holes formed on a plurality of protrusions, one end of each of the plurality of through holes extending into a conical groove, the edges of some of the through holes being attached to both sides of the blocking block, a fixing plate being provided on the top of each of the plurality of protrusions, a plurality of sleeves being provided on the top of each of the plurality of fixing plates, the plurality of sleeves being aligned with the plurality of through holes, and an adjustment mechanism being provided inside each of the plurality of sleeves.

[0007] Preferably, a protective cover is provided at the top of the sleeve tube.

[0008] Preferably, the adjusting mechanism includes a first sealing plug slidably disposed within the sleeve tube. The first sealing plug is slidably disposed within the sleeve tube, and a fixing post is installed at the bottom of the sealing plug. One end of the fixing post extends to the through hole and is fitted with a second sealing plug. The second sealing plug is slidably disposed within the through hole. A first guide hole is provided at the bottom of the outer side of each of the plurality of protrusions. The first guide hole communicates with the through hole. A plurality of first connecting holes are provided at the top of the interior of the plurality of sleeve tubes. A plurality of second connecting holes are provided on the inner side of the top of the through hole, and there is a gap between the second connecting holes and the first guide holes. In one of the working states, the first connecting holes and the second connecting holes are connected.

[0009] Preferably, both the first sealing plug and the second sealing plug have a wear-resistant coating on their outer sides.

[0010] Preferably, the protrusions are spaced apart, and the sleeves on the fixing plate are spaced apart.

[0011] Preferably, the first tray is provided with a plurality of grooves, and the second flow guide hole is arranged on the plurality of grooves.

[0012] The floating valve tray with sufficient gas-liquid contact proposed in this invention has the following advantages: 1. The rising gas will first pass through the second guide hole of the first tray and enter the gap between the first tray and the second tray, so that the rising gas will flow in the conical groove. During the movement of the second sealing plug, the guide hole will be connected with the space at the bottom of the second sealing plug, so that the area around the protrusion will make bubbling contact with the liquid layer of the tray, thereby improving the gas-liquid contact effect. 2. As the gas velocity increases, the rising gas will push the second sealing plug to continue to rise and move, allowing the first sealing plug to move to the first connecting hole and the second sealing plug to move to the second connecting hole. The first connecting hole on the sleeve tube and the second connecting hole on the through hole are aligned to form a secondary flow channel, thereby increasing the contact position between the gas and the liquid, thus greatly optimizing the sufficiency of gas-liquid contact. 3. The first tray is provided with several grooves and the second guide hole is arranged on the grooves and ... Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1: Refer to Figure 1-6 A floating valve tray with sufficient gas-liquid contact includes a fixed frame 1, a first tray 2 fixedly installed at the bottom of the fixed frame 1, a plurality of second guide holes 17 provided on the first tray 2, a second tray 3 fixedly installed at the top of the fixed frame 1, a plurality of protrusions 4 provided at the top of the second tray 3, a plurality of floating valve assemblies evenly provided on the top of the plurality of protrusions 4, the plurality of floating valve assemblies all extending above the top of the first tray 2, a conical groove 5 opened at the bottom of the second tray 3, a blocking block 6 provided in the middle of the conical groove 5, the two sides of the blocking block 5 being aligned with the bottom edge of the floating valve assembly; The float valve assembly includes through holes 7 formed on several protrusions 4, one end of each through hole 7 extending into a tapered groove 5. The edges of some through holes 7 are fitted to both sides of a blocking block 6. A fixing plate 8 is fixedly mounted on the top of each of the protrusions 4. Several sleeves 9 are welded to the top of each fixing plate 8. The sleeves 9 are aligned with the through holes 7, and an adjustment mechanism is provided inside each sleeve 9. The adjusting mechanism includes a first sealing plug 10 slidably disposed within the sleeve tube 9. The first sealing plug 10 is slidably disposed within the sleeve tube 9. A fixing post 11 is fixedly installed at the bottom of the sealing plug 10. One end of the fixing post 11 extends to the through hole 7 and is fixedly installed with a second sealing plug 12. The second sealing plug 12 is slidably disposed within the through hole 7. A guide hole 13 is provided at the bottom of the outer side of several protrusions 4. The guide hole 13 is connected to the through hole 7. A number of first connecting holes 14 are provided at the top of several sleeve tubes 9. A number of second connecting holes 15 are provided on the inner side of the top of the through hole 7. There is a gap between the second connecting holes 15 and the guide holes 13. In one working state, the first connecting holes 14 and the second connecting holes 15 are connected.

[0022] Working principle: The rising gas first enters the gap between the first tray 2 and the second tray 3 through the first guide hole 17 of the first tray 2, allowing the rising gas to flow in the conical groove 5. The rising gas reaches the bottom of the second sealing plug 12 through several through holes 7, driving the second sealing plug 12 to move within the through holes 7. During the movement of the second sealing plug 12, the guide hole 13 connects with the space at the bottom of the second sealing plug 12, allowing the area around the protrusion to bubble and contact the liquid layer of the tray. As the gas velocity increases, the rising gas pushes the second sealing plug 12 to continue moving upward, allowing the second sealing plug 12 to move along with the first sealing plug 10 through the fixed column 11. The first sealing plug 10 moves within the sleeve tube 9, moving to the first connecting hole 14 and the second sealing plug 10 to the second connecting hole 15. The first connecting hole 14 on the sleeve tube 9 and the second connecting hole 15 on the through holes 7 are aligned, forming a secondary flow channel, increasing the contact points between the gas and liquid, thereby increasing the sufficiency of gas-liquid contact.

[0023] Example 2: In Example 1, the top of the sleeve 9 is in an open state, and direct airflow impact may cause unstable pressure fluctuations. Based on Example 1, optimizations are made, referring to... Figure 1-6 The top of the sleeve tube 9 is provided with a protective cover 18, which makes the first sealing plug 11 inside the sleeve tube 9 operate more stably, thereby improving the stability of the tray and improving the gas-liquid contact effect. Furthermore, both the outer sides of the first sealing plug 10 and the second sealing plug 12 are provided with wear-resistant coatings. These coatings are made of a composite of various materials (such as ceramic particles and graphite), which improve the mechanical properties of the first sealing plug 10 and the second sealing plug 12, effectively increasing their service life and making the tray more durable.

[0024] Example 3: In Example 1, during the process of gas and liquid passing through the through-hole 7, the uneven distribution of the through-hole 7 can easily lead to insufficient contact between some gas and liquid, thus affecting the performance of the device. Based on Example 1, optimizations are made, referring to... Figure 1-6 The protrusions 4 are spaced apart, and the sleeves 9 on the fixing plate 8 are spaced apart, so that the arrangement of the through holes 7 is more uniform, reducing the occurrence of gas or liquid accumulation on one side, thereby improving the gas-liquid contact exchange effect.

[0025] Example 4: In Example 1, when the first tray 2 is arranged in a planar configuration, the gas and liquid flow velocities above the first tray 2 are consistent, resulting in poor gas-liquid contact between the first tray 2 and the liquid. Based on Example 1, optimizations are made, referring to... Figure 1-6 The first tray 2 is provided with a number of grooves 16, and the second guide hole 17 is arranged on the grooves 16. The grooves 16 cause changes in the gas-liquid flow velocity, thereby improving the gas-liquid contact exchange efficiency on the first tray 2 and thus increasing the overall gas-liquid contact effect of the device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
