Description

Sealing structure of water seal tank for water electrolysis hydrogen production equipment

Technical Field

The utility model relates to the technical field of water electrolysis hydrogen production equipment, in particular to a sealing structure of a water seal tank of water electrolysis hydrogen production equipment.

Background technique

Hydrogen production by water electrolysis is a relatively convenient method for producing hydrogen. In the process of hydrogen production by water electrolysis, a water seal tank is required to prevent the occurrence of flashback. When the flare exhaust gas enters the water seal tank, the sealing liquid will fluctuate violently due to the impact of the venting gas, which may cause the exhaust gas inlet to separate from the sealing liquid, resulting in a dangerous accident.

Based on the above situation, patent publication number CN203604989U discloses a water seal tank sealing device, which can prevent the impact force from driving the sealing liquid to fluctuate and cause it to separate from the bottom of the exhaust gas inlet by setting a sieve plate at the bottom of the water seal tank. However, in the above scheme, the sieve plate is in an inactive state and cannot change its angle. It is easy to be damaged after being subjected to impact force multiple times.

Utility Model Content

In order to overcome the shortcomings of the prior art, the utility model provides a sealing structure of a water seal tank for water electrolysis hydrogen production equipment. When in use, the hinged parts are arranged so that the hinged parts can be deformed at any angle, so that the limit plate can be at different angles and withstand impact forces in different directions, thereby avoiding the problem that the limit plate is easily damaged when being fixed horizontally.

To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: the sealing structure of the water seal tank used for water electrolysis hydrogen production equipment includes a tank body, one side of the top outer wall of the tank body is connected to a flare exhaust gas inlet, the lower end of the flare exhaust gas inlet extends to the bottom end of the tank body, and the other side of the top outer wall is connected to a flare exhaust gas outlet, and the tank body is provided with mounting blocks symmetrically fixed on the inner walls on both sides of the tank body, and a limiting plate connected between the two mounting blocks; a through hole is opened on the limiting plate corresponding to the flare exhaust gas inlet, and the flare exhaust gas inlet extends downward through the through hole; hinges are distributed on the outer walls on both sides of the limiting plate, and the hinges are connected to the mounting blocks.

As a preferred technical solution of the utility model, a movable groove is opened in the mounting block, and the hinge includes a butterfly spring fixedly connected to the outer wall surface of the limiting plate, one end of the butterfly spring extends into the movable groove, and a support plate is installed on its end, a rotating block is fixed on the support plate, and a rotating groove is connected to the side of the movable groove close to the rotating block, the rotating groove is adapted to the shape and size of the rotating block, and the rotating block rotates in the rotating groove.

As a preferred technical solution of the utility model, the rotating block is spherical, and the rotating groove is a spherical groove adapted to the rotating block.

As a preferred technical solution of the utility model, the limiting plate is a flexible plate with sieve holes evenly distributed thereon, and the aperture of the sieve holes is greater than 6 mm.

As a preferred technical solution of the utility model, the tank body is filled with sealing liquid, the limit plate is immersed in the sealing liquid, and the minimum movable range height is greater than the minimum liquid level height of the sealing liquid.

As a preferred technical solution of the utility model, support legs are symmetrically arranged on both sides of the outer wall of the bottom end of the tank body.

Compared with the prior art, the utility model has the following beneficial effects:

(1) When the utility model is in use, the exhaust gas enters the tank body and generates an impact force when passing through the limit plate, which drives the limit plate to fluctuate up and down. Since the minimum activity range height of the limit plate is greater than the minimum liquid level height of the sealing liquid, the bottom of the flare exhaust gas inlet can be moderately located in the sealing liquid, which can prevent the violent fluctuations caused by the air impact from causing the bottom of the flare exhaust gas inlet to separate from the sealing liquid. In addition, through the provided hinge, the hinge can be deformed at any angle, which can make the limit plate at different angles and withstand impact forces in different directions, avoiding the problem that the limit plate is fixed horizontally and is easily damaged when impacted;

(2) When the utility model is in use, the exhaust gas is discharged into the gas phase space of the tank body through the sieve holes on the limit plate. The exhaust gas generates an impact force when passing through the limit plate, and the impact force drives the limit plate to rise and fall. The limit plate is set as a flexible plate with deformation ability, which can reduce the damage caused by the impact force to the limit plate and extend the service life of the limit plate.

Detailed ways

The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

Embodiment:

As shown in Figures 1, 2 and 3, the utility model provides a sealing structure of a water seal tank for water electrolysis hydrogen production equipment, including a tank body 1, the tank body 1 is filled with a sealing liquid, one side of the top outer wall of the tank body 1 is connected to a flare exhaust gas inlet 2, the lower end of the flare exhaust gas inlet 2 extends to the bottom end of the tank body 1, and the other side of the top outer wall is connected to a flare exhaust gas outlet 3, two mounting blocks 6 are symmetrically fixed on the inner walls of both sides of the tank body 1, a limiting plate 5 is connected between the two mounting blocks 6, a through hole 12 is opened on the limiting plate 5 corresponding to the flare exhaust gas inlet 2, the limiting plate 5 is immersed in the sealing liquid, and the flare exhaust gas inlet 2 extends downward through the through hole 12 ; A movable groove 7 is opened in the mounting block 6, and hinges are distributed on the outer walls on both sides of the limit plate 5. The hinges are connected to the movable groove 7 in the mounting block 6, and the hinges include a butterfly spring 8 fixedly connected to the outer wall of the limit plate 5, one end of the butterfly spring 8 extends into the movable groove 7, and a support plate 9 is installed on its end, and a rotating block 10 is fixed on the support plate 9. A rotating groove 11 is connected to the side of the movable groove 7 close to the rotating block 10, and the rotating groove 11 is adapted to the shape and size of the rotating block 10, and the rotating block 10 rotates in the rotating groove 11; the minimum movable range height of the limit plate 5 is greater than the minimum liquid level height of the sealing liquid.

When the water seal tank is in use, a large amount of flare exhaust gas is discharged into the flare system, and first enters the tank body 1 through the flare exhaust gas inlet 2. After the gas phase pressure of the flare exhaust gas inlet 2 accumulates to a certain pressure, it will break through the liquid seal pressure of the sealing liquid in the tank body 1. The exhaust gas generates an impact force when passing through the limit plate 5, and the impact force drives the limit plate 5 up and down. When the limit plate 5 is floating, it drives the butterfly spring 8 to deform, and the butterfly spring 8 pulls the support plate 9. When the limit plate 5 is in different positions, the butterfly spring 8 makes the support plate 9 have different angles of inclination. At this time, the support plate 9 drives the rotating block 10 rotates in the rotating groove 11, so that the limit plate 5 can withstand impact forces in different directions, that is, no matter what angle the limit plate 5 is at, it can be displaced by rotating the rotating block 10 in the rotating groove 11. Since the minimum activity range height of the limit plate 5 is greater than the minimum liquid level height of the sealing liquid, the bottom of the flare exhaust gas inlet 2 can be moderately located in the sealing liquid, which can prevent the violent fluctuations caused by air impact from causing the bottom of the flare exhaust gas inlet 2 to separate from the sealing liquid. In addition, the device uses a hinged part to allow the limit plate 5 to be at different angles and withstand impact forces in different directions.

As shown in FIG. 1 , FIG. 2 , and FIG. 3 , the rotating block 10 is spherical, and the rotating groove 11 is a spherical groove adapted to the rotating block 10 ;

When the water seal tank is in use, a large amount of flare exhaust gas is discharged into the flare system, and it first enters the tank body 1 through the flare exhaust gas inlet 2. After the gas phase pressure of the flare exhaust gas inlet 2 accumulates to a certain pressure, it will break through the liquid sealing pressure of the sealing liquid in the tank body 1. The exhaust gas generates an impact force when passing through the limit plate 5, and the impact force drives the limit plate 5 up and down. When the limit plate 5 is floating, it drives the butterfly spring 8 to deform, and the butterfly spring 8 pulls the support plate 9. When the limit plate 5 is in different positions, the butterfly spring 8 makes the support plate 9 have different angles of inclination. At this time, the support plate 9 drives the spherical rotating block 10 to rotate in the spherical rotating groove 11, so that the limit plate 5 can withstand impact forces in different directions.

As shown in FIG. 1 and FIG. 4 , the limit plate 5 is a flexible plate on which sieve holes are evenly distributed, and the aperture of the sieve holes is greater than 6 mm. A layer of anti-corrosion coating is also provided on the outer surface of the limit plate 5;

When the water-sealed tank is in use, a large amount of flare exhaust gas is discharged into the flare system, and first enters the tank body 1 through the flare exhaust gas inlet 2. After the gas phase pressure of the flare exhaust gas inlet 2 accumulates to a certain pressure, it will break through the liquid sealing pressure of the sealing liquid in the tank body 1, and then the exhaust gas is discharged into the gas phase space of the tank body 1 through the sieve holes on the limiting plate 5. The larger sieve holes are convenient for the exhaust gas to be discharged; and the exhaust gas generates impact force when passing through the limiting plate 5, and the impact force drives the limiting plate 5 to fluctuate up and down. The limiting plate 5 is set to be a flexible plate, which has deformation ability, and can reduce the damage caused by the impact force to the limiting plate 5. At the same time, the anti-corrosion coating on the limiting plate 5 also improves the anti-corrosion performance of the limiting plate 5, and extends the service life of the limiting plate 5.

As shown in FIG1 , support legs 4 are symmetrically arranged on both sides of the outer wall of the bottom end of the tank body 1; when the water seal tank is in use, the two support legs 4 welded on the outer wall of the bottom end of the water seal tank can support and stabilize the water seal tank and fix it on the ground.

According to the above embodiments, the present utility model can be well implemented.
