A high-efficiency gas-liquid distributor for a methanol washing device

Abstract

This utility model discloses a high-efficiency gas-liquid distributor for a methanol washing device, including a body and support legs for supporting the body. A wastewater discharge port is fixedly installed at the bottom of the body, and an air inlet and a waste gas discharge port are fixedly installed at the side of the body. A water inlet pipe is fixedly installed inside the body, and slits are provided on both sides of the water inlet pipe. This high-efficiency gas-liquid distributor for the methanol washing device adopts a dual-tangential inlet design with an inlet angle of 90°. When the methane solution enters the inside of the water inlet pipe through the connecting pipe, the methane solution flows downward through a spiral guide vane with a guide angle of 45°. As the liquid flows downward, it generates outward centrifugal force, causing the liquid to splash outward through a conical diffuser when it reaches the bottom of the water inlet pipe. The diffused liquid is evenly distributed on the upper end of the distribution plate, thus avoiding the "channeling" phenomenon of the solution on the upper end of the distribution plate caused by direct-flow injection.

Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a high-efficiency gas-liquid distributor for a methanol washing device. Background Technology

[0002] In fields such as coal chemical industry and natural gas purification, methanol washing is a key technology for removing acidic gases. However, traditional gas-liquid distributors have the following technical shortcomings:

[0003] 1. Uneven distribution problem: Sieve plate distributors are prone to "channeling" phenomenon, resulting in insufficient gas-liquid contact in local areas;

[0004] 3. Blockage problem: Solid particles such as sulfides tend to deposit at the conical holes. Traditional designs lack self-cleaning function and require frequent shutdowns for cleaning.

[0005] To address the aforementioned issues, we have developed an innovative design based on the existing high-efficiency gas-liquid distributor structure used in methanol washing units. Utility Model Content

[0006] The purpose of this utility model is to provide a high-efficiency gas-liquid distributor for a methanol washing device, so as to solve the problems mentioned in the background art, such as uneven distribution of traditional gas-liquid distributors, the "channeling" phenomenon easily generated by sieve plate distributors, insufficient gas-liquid contact in local areas, blockage problems, solid particles such as sulfides easily depositing at the conical holes, and the lack of self-cleaning function in traditional designs, which require frequent shutdowns for cleaning.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency gas-liquid distributor for a methanol washing device, comprising a body and support legs for supporting the body; a wastewater discharge port is fixedly installed at the bottom of the body, and an air inlet and a waste gas discharge port are fixedly installed at the side of the body; a water inlet pipe is fixedly installed inside the body, and cuts are made on both sides of the water inlet pipe, and connecting pipes are fixedly connected to the cuts at both ends, and the tail end of the connecting pipe is connected to an external methane liquid supply device; a spiral guide vane is fixedly installed inside the water inlet pipe, and a conical diffuser is fixedly connected to the bottom of the water inlet pipe.

[0008] Preferably, solenoid valves are fixedly installed on the outside of the sewage outlet, air inlet, and exhaust outlet;

[0009] This structure allows for the adjustment of the opening states of the sewage discharge port, air inlet, and exhaust gas discharge port via solenoid valves, which are powered by an external power source.

[0010] Preferably, the conical diffuser is viewed as an inverted conical structure;

[0011] This conical diffuser structure, viewed as an inverted cone shape, allows for greater diffusion of centrifugal liquid within the valve at the top of the distribution plate.

[0012] Preferably, a distribution plate is fixedly installed on the inner side of the machine body, and conical holes are equidistantly opened on the inner side of the distribution plate;

[0013] The equally spaced conical holes in this structure allow the liquid to come into contact with the gas in a droplet state.

[0014] Preferably, the tapered hole is viewed as a "V" shaped structure;

[0015] This conical orifice structure, viewed as a "V" shape, allows for better contact between the droplet and the gas.

[0016] Preferably, a support plate is fixedly installed on the inner side of the machine body, and a guide rod is slidably connected to the inner side of the support plate. A telescopic spring is connected between the end of the guide rod and the support plate. A support frame is fixedly connected to the top of the guide rod, and a protrusion is fixedly connected to the outer side of the support frame. The protrusion side is considered to be a semi-circular structure.

[0017] This structure allows the support plate to reset itself using the elastic force of a telescopic spring, thus allowing the unblocking rod to pass through the inside of the tapered hole.

[0018] Preferably, the top of the support plate is equipped with a drain rod at an equal angle, and the top of the drain rod has a conical structure, and the drain rod and the conical hole are distributed in a one-to-one correspondence;

[0019] This structure, with the unblocking rod and conical holes arranged in a one-to-one correspondence, allows the unblocking rod to unclog multiple sets of conical holes at the upper end.

[0020] Preferably, a drive motor is fixedly installed on the outside of the machine body, and the output end of the drive motor passes through the inside of the machine body, and a cam is fixedly connected to the output end of the drive motor.

[0021] This structure uses a cam to press the protrusion downwards, thereby causing the drain rod to move downwards.

[0022] Compared with the prior art, the beneficial effect of this utility model is that the methanol washing device is equipped with a high-efficiency gas-liquid distributor:

[0023] 1. Swirl pre-distribution structure: This structure adopts a double tangential inlet design with an inlet angle of 90°. When the methane solution enters the inner side of the inlet pipe through the connecting pipe, the methane solution will flow downward through the spiral guide vane with a guide angle of 45°. When the liquid flows downward, it will generate outward centrifugal force, so that when the liquid flows to the bottom of the inlet pipe, it will be splashed outward through the conical diffuser. The diffused liquid will be evenly distributed on the upper end of the distribution plate, thus avoiding the "channeling" phenomenon of the solution on the upper end of the distribution plate caused by direct injection, which would result in insufficient gas-liquid contact in some areas. The solution distributed on the upper end of the distribution plate will enter the inner side of the evenly spaced conical holes to form drips, so that the gas to be treated entering from the gas inlet and the falling droplets can achieve efficient mass transfer below the distribution plate, thereby efficiently removing acidic components from the gas.

[0024] 2. Anti-clogging structure: When solid particles such as sulfides in the gas being treated tend to deposit at the bottom of the conical hole, causing blockage, the drive motor is activated. The output of the drive motor drives the cam to rotate. When the cam rotates, the cam head is generated, and the protrusion loses its cam limit. The support frame is reset by the elastic force of the telescopic spring, thereby causing the support frame to move multiple sets of unblocking rods upward to pierce into the inside of the conical hole. After the cam rotates 360°, the cam head contacts the upper end of the protrusion again, and the cam presses the protrusion, causing the support frame to compress the telescopic spring and move downward, thereby causing the unblocking rod to slide out from the inside of the conical hole. Through the above structure, the unblocking rod completes one unblocking of the conical hole, preventing blockage during use. Attached Figure Description

Detailed Implementation

[0032] 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.

[0033] Please see Figures 1-6 This utility model provides a technical solution: a high-efficiency gas-liquid distributor for a methanol washing device, comprising:

[0034] Example 1: As Figures 1-4 The present invention provides a technical solution: a high-efficiency gas-liquid distributor for a methanol washing device, comprising: a body 1 and a support leg 2 for supporting the body 1; a sewage discharge port 3 is fixedly installed at the bottom of the body 1, and an air inlet 4 is fixedly installed at the side end of the body 1, and an exhaust gas discharge port 5 is fixedly installed at the side end of the body 1; a water inlet pipe 7 is fixedly installed inside the body 1, and cuts 8 are provided on both sides of the water inlet pipe 7, and connecting pipes 9 are fixedly connected to the cuts 8 at both ends, and the tail end of the connecting pipe 9 is connected to an external methane liquid supply device; a spiral guide vane 10 is fixedly installed inside the water inlet pipe 7, and a conical diffuser 11 is fixedly connected to the bottom of the water inlet pipe 7;

[0035] Solenoid valves 6 are fixedly installed on the outside of the sewage discharge outlet 3, the air inlet 4 and the exhaust outlet 5; the conical diffuser 11 is an inverted cone-shaped structure when viewed from the front; a distribution plate 12 is fixedly installed on the inside of the body 1, and conical holes 13 are equidistantly opened on the inside of the distribution plate 12; the conical holes 13 are a “V” shaped structure when viewed from the front.

[0036] This structure adopts a dual-tangential inlet design with an inlet angle of 90°. When the methane solution enters the inner side of the inlet pipe 7 through the connecting pipe 9, the methane solution will flow downward through the spiral guide vane 10 with a guide angle of 45°. When the liquid flows downward, it will generate outward centrifugal force, so that when the liquid flows to the bottom of the inlet pipe 7, it will be splashed outward through the conical diffuser 11. The diffused liquid will be evenly distributed on the upper end of the distribution plate 12, thereby avoiding the "channeling" phenomenon of the solution on the upper end of the distribution plate 12 caused by direct injection, which would result in insufficient gas-liquid contact in some areas. The solution distributed on the upper end of the distribution plate 12 will enter the inner side of the evenly spaced conical holes 13 to form a drip, thereby achieving efficient mass transfer between the gas to be treated entering from the air inlet 4 and the falling droplets below the distribution plate 12, thus efficiently removing acidic components from the gas.

[0037] Example 2: Figures 1-3 , Figures 5-6 The present invention provides a technical solution: a high-efficiency gas-liquid distributor for a methanol washing device, comprising: a support plate 14 fixedly installed on the inner side of the body 1, a guide rod 15 slidably connected to the inner side of the support plate 14, and a telescopic spring 16 connected between the end of the guide rod 15 and the support plate 14; a support frame 17 fixedly connected to the top of the guide rod 15, and a protrusion 18 fixedly connected to the outer side of the support frame 17, with the protrusion 18 being considered as a semi-circular structure; a dredging rod 19 installed at equal angles on the top of the support plate 14, with the top of the dredging rod 19 having a conical structure, and the dredging rod 19 and the conical hole 13 being distributed in a one-to-one correspondence; a drive motor 20 fixedly installed on the outer side of the body 1, with the output end of the drive motor 20 penetrating through the inner side of the body 1, and a cam 21 fixedly connected to the output end of the drive motor 20;

[0038] When solid particles such as sulfides in the gas to be treated tend to deposit at the bottom of the conical hole 13, causing blockage, the drive motor 20 is activated. The output of the drive motor 20 drives the cam 21 to rotate. When the cam 21 rotates, the head of the cam 21 is generated, and the protrusion 18 loses its limit. The support frame 17 is reset by the elastic force of the telescopic spring 16, thereby causing the support frame 17 to drive multiple sets of unblocking rods 19 to move upward and pierce into the inner side of the conical hole 13. After the cam 21 rotates 360°, the head of the cam 21 contacts the upper end of the protrusion 18 again. The cam 21 will press the protrusion 18, thereby causing the support frame 17 to compress the telescopic spring 16 and move downward, so that the unblocking rods 19 slide out from the inner side of the conical hole 13. Through the above structure, the unblocking rods 19 complete one unblocking of the conical hole 13, avoiding blockage during use.
