Description

Technical Field

[0001] This utility model relates to the field of distributor technology, and in particular to an anti-clogging gas distributor. Background Technology

[0002] In equipment such as packed towers and reaction towers in chemical, environmental protection, and pharmaceutical fields, gas distributors are one of the core components for achieving efficient gas-liquid two-phase contact and ensuring reaction or separation effects. Their main function is to evenly distribute the gas entering the tower to the cross-section of the tower body, ensuring that the gas is in full contact with the packing layer or liquid, thereby improving mass transfer and heat transfer efficiency.

[0003] However, existing gas distributors generally face clogging problems in practical applications. For example, the raw gas in industrial production often carries impurities such as dust, tar, and polymer particles. These impurities tend to adhere to and accumulate on the inner wall of the gas distribution channel of the distributor. As the operating time increases, the impurities will gradually reduce the effective flow cross-section of the gas distribution channel, or even completely block the channel, resulting in uneven gas distribution and local "flow deviation" and "dead zone" phenomena in the tower, which seriously reduces the equipment's processing capacity.

[0004] Therefore, it is necessary to provide a new anti-clogging gas distributor to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an anti-clogging gas distributor.

[0006] The anti-clogging gas distributor provided by this utility model includes a distributor body, on which a plurality of evenly distributed air distribution channels are provided, and an anti-clogging component is installed in each of the air distribution channels.

[0007] The anti-clogging component includes a steel ball, which is slidably installed in the air distribution channel. A connecting rod is fixedly installed at the bottom of the steel ball. The bottom of the connecting rod extends out of the air distribution channel and is fixedly installed with a pressing plate. The pressing plate is provided with a tension spring connected to the distributor body.

[0008] Preferably, the anti-clogging component further includes a guide plate, which is fixedly installed at the bottom of the distributor body and coaxially arranged with the air distribution channel. The connecting rod passes through a through hole opened at the center of the guide plate and is slidably connected to the through hole.

[0009] Preferably, the tension spring is sleeved on the docking rod, one end of the tension spring is fixedly connected to the upper surface of the abutment plate, and the other end of the tension spring is fixedly connected to the lower surface of the guide plate.

[0010] Preferably, the guide plate has a plurality of annularly distributed air distribution holes, and the abutment plate has a plurality of overflow holes.

[0011] Preferably, the air distribution channel includes a sealing hole and a conical hole, the sealing hole and the conical hole are distributed vertically, and the diameter of the sealing hole is smaller than the diameter of the conical hole.

[0012] Preferably, the diameter of the steel ball is the same as the diameter of the sealing hole, and one half of the steel ball extends out of the sealing hole.

[0013] Preferably, the edge of the distributor body is fixedly fitted with an installation edge, and the installation edge is provided with a plurality of annularly distributed installation holes.

[0014] Compared with related technologies, the anti-clogging gas distributor provided by this utility model has the following beneficial effects:

[0015] When gas enters the tower space above the distributor body, the increased gas pressure drives the steel ball to slide down the sealing hole into the conical hole. At the same time, the contact plate stretches the tension spring, so the gas can be guided and evenly distributed through each gas distribution channel. After the gas flow is complete, the steel ball resets under the action of the tension spring, thus the gas distribution channel is blocked again. During this reset process, the steel ball can push out the impurities remaining in the sealing hole, forming a "self-cleaning" effect, which greatly reduces the probability of blockage and reduces the number of times the equipment needs to be shut down for cleaning.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides an anti-clogging gas distributor, which includes a distributor body 1 and an anti-clogging component 2. An installation edge 11 is fixedly fitted at the edge of the distributor body 1, and a plurality of annularly distributed installation holes 11a are provided on the installation edge 11. The distributor body 1 is fixed in the packed tower by means of the installation holes 11a.

[0024] In the embodiments of this utility model, please refer to Figures 1 to 4 The main body 1 of the distributor has several evenly distributed air distribution channels 1a. Each air distribution channel 1a includes a blocking hole 1a1 and a conical hole 1a2. The blocking hole 1a1 and the conical hole 1a2 are distributed vertically, and the diameter of the blocking hole 1a1 is smaller than the diameter of the conical hole 1a2. Each air distribution channel 1a is equipped with an anti-blocking component 2.

[0025] The anti-clogging component 2 includes a steel ball 21, the diameter of which is the same as the diameter of the sealing hole 1a1, and one half of the steel ball 21 extends out of the sealing hole 1a1. The steel ball 21 is slidably installed in the air distribution channel 1a, and a connecting rod 22 is fixedly installed at the bottom of the steel ball 21. The bottom of the connecting rod 22 extends out of the air distribution channel 1a and is fixedly installed with a contact plate 23. The contact plate 23 is provided with a tension spring 24 connected to the distributor body 1. The anti-clogging component 2 also includes a guide plate 25. The guide plate 25 is fixedly installed at the bottom of the distributor body 1 and is coaxially arranged with the air distribution channel 1a. The connecting rod 22 passes through the through hole opened at the center of the guide plate 25 and is slidably connected with the through hole. The tension spring 24 is sleeved on the connecting rod 22. One end of the tension spring 24 is fixedly connected to the upper surface of the abutment plate 23, and the other end of the tension spring 24 is fixedly connected to the lower surface of the guide plate 25. The guide plate 25 is provided with a number of annularly distributed air distribution holes 25a, and the abutment plate 23 is provided with a number of overflow holes 23a.

[0026] It should be noted that in the initial state, under the action of the tension spring 24, the steel ball 21 is driven to seal the sealing hole 1a1, so gas and impurities cannot enter the air distribution channel 1a, thus protecting the air distribution channel 1a. When the gas enters the tower space above the distributor body 1, as the gas pressure increases, the steel ball 21 is driven to slide down along the sealing hole 1a1 into the conical hole 1a2. At the same time, the abutment plate 23 stretches the tension spring 24, so the gas can be guided and evenly distributed through each air distribution channel 1a. When the gas flow is completed, the steel ball 21 resets under the action of the tension spring 24, so the air distribution channel 1a is blocked again. In this reset process, the steel ball 21 can push out the impurities remaining in the sealing hole 1a1, forming a "self-cleaning" effect, greatly reducing the probability of blockage and reducing the number of times the equipment is shut down for cleaning.

[0027] Among them, the main body of the distributor 1 has several uniformly distributed gas distribution channels 1a to achieve initial uniform gas distribution. Secondly, the conical holes 1a2 of the gas distribution channels 1a can guide and diffuse the gas, avoiding the generation of eddies in the gas within the channels. Finally, the gas distribution holes 25a of the guide plate 25 and the overflow holes 23a of the abutment plate 23 form a secondary flow division, allowing the gas to further diffuse after passing through the gas distribution channels 1a, ultimately forming a uniform velocity field within the tower and improving the gas-liquid contact efficiency.

[0028] In addition, to eliminate the potential risk of elastic failure due to rust caused by contact with liquid, the tension spring 24 is made of stainless steel or titanium alloy to improve corrosion resistance. At the same time, a polytetrafluoroethylene (PTFE) coating is applied to the surface of the tension spring 24 to enhance its rust prevention ability.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
