Description

Technical Field

[0001] The utility model relates to the technical field of flame arresters, in particular to a bubble-cap type overflow water seal flame arrester. Background Art

[0002] Flame arresters are safety devices used to prevent the spread of flames of flammable gases and flammable liquid vapors. They are generally installed in pipelines that transport flammable gases or on ventilated tanks to prevent the spread of flames (deflagration or detonation). They are composed of a flame arrester core, a flame arrester shell and accessories. Flame arresters are also commonly used in pipelines that transport flammable gases. If the flammable gas is ignited, the gas flame will spread to the entire pipeline network. In order to prevent this danger from occurring, flame arresters must also be used. Flame arresters can also be used on pipelines with open flame equipment to prevent flashback accidents, but they cannot prevent the open flame combustion of flammable gases and liquids that are burning in the open.

[0003] The water level sensor or control device of the existing bubble-type overflow water seal flame arrester needs to transmit the liquid level signal to the controller. After the controller performs logical operation on the signal, it issues an instruction to control the valve to open. When gas enters the water through the air intake elbow, more bubbles will be generated, resulting in frequent water surface fluctuations. The sensor is easily affected and the accuracy is inaccurate, resulting in misjudgment, which affects the accuracy of the water seal flame arrester. In view of the above problems, the inventor proposes a bubble-type overflow water seal flame arrester to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Figure 1-4 As shown, the utility model provides a bubble-cap overflow water-sealed flame arrester, comprising an explosion-proof tank 1, a liquid level stabilizing component 2 is slidably installed inside the explosion-proof tank 1 of the water-sealed flame arrester, the liquid level stabilizing component 2 of the water-sealed flame arrester comprises a floating plate 21, and the floating plate 21 is slidably clamped inside the explosion-proof tank 1, a plurality of evenly distributed fixing holes 22 are opened on the floating plate 21 of the water-sealed flame arrester, a liquid level control component 3 is fixedly installed inside the explosion-proof tank 1 of the water-sealed flame arrester, the liquid level control component 3 of the water-sealed flame arrester comprises a fixing rod 31, and the fixing rod 31 is fixedly inserted in the floating plate 21, a first tooth plate 32 is fixedly installed on the top of the fixing rod 31 of the water-sealed flame arrester, and a second tooth plate is fixedly installed on the bottom of the fixing rod 31 of the water-sealed flame arrester 33. When the gas enters the water in the explosion-proof tank 1 through the air inlet elbow 11, and then precipitates from the water and is discharged through the air outlet pipe 12, the water in the explosion-proof tank 1 will form a water seal state for the air inlet elbow 11 and the air outlet pipe 12. When an explosion occurs at one end, a continuous explosion cannot be formed under the isolation of the water seal. However, when the gas enters the water through the air inlet elbow 11, more bubbles will be generated, resulting in frequent fluctuations in the liquid level. At this time, the floating plate 21 in the explosion-proof tank 1 will stabilize the liquid level. The gas in the water will precipitate out of the water through the fixing holes 22 on the floating plate 21. The floating plate 21 will also rise and fall with the rise and fall of the water level in the explosion-proof tank 1. When the floating plate 21 rises and falls, it will drive the fixing rod 31 to rise and fall.

[0020] A water injection pipe 18 and a drainage pipe 19 are fixedly installed on one side of the water seal flame arrester explosion-proof tank 1 and are distributed vertically, and the water injection pipe 18 and the drainage pipe 19 are both connected to the inside of the explosion-proof tank 1.

[0021] By adopting the above technical solution, an external water source is connected to inject water into the explosion-proof tank 1 through the water injection pipe 18. When the water level in the explosion-proof tank 1 is too high, the water in the explosion-proof tank 1 will be discharged through the drain pipe 19.

[0022] A first valve 181 is rotatably mounted on the water injection pipe 18 of the water seal flame arrester. The first valve 181 of the water seal flame arrester is provided with a plurality of tooth grooves distributed in an annular manner, and the first valve 181 is meshed with the first tooth plate 32 through the tooth grooves.

[0023] By adopting the above technical solution, an external water source is connected to inject water into the explosion-proof tank 1 through the water injection pipe 18. As the water level rises, the floating plate 21 in the explosion-proof tank 1 rises, and the floating plate 21 drives the fixed rod 31 to rise. When the water level in the explosion-proof tank 1 reaches a specified height, the first tooth plate 32 on the fixed rod 31 drives the first valve 181 on the water injection pipe 18 to rotate until it is closed.

[0024] A second valve 191 is rotatably mounted on the drain pipe 19 of the water-sealed flame arrester. A plurality of tooth grooves distributed in an annular pattern are formed on the second valve 191 of the water-sealed flame arrester, and the second valve 191 is meshed with the second tooth plate 33 through the tooth grooves.

[0025] By adopting the above technical solution, an external water source is connected to inject water into the explosion-proof tank 1 through the water injection pipe 18. As the water level rises, the floating plate 21 in the explosion-proof tank 1 rises, and the floating plate 21 drives the fixed rod 31 to rise. The second tooth plate 33 on the fixed rod 31 drives the second valve 191 on the drain pipe 19 to rotate and open, and the water inside the explosion-proof tank 1 will be discharged through the drain pipe 19, so that the water level inside the explosion-proof tank 1 always maintains a suitable height.

[0026] An air intake elbow 11 is fixedly installed on one side of the water seal flame arrester explosion-proof tank 1, and the air intake elbow 11 is communicated with the inside of the explosion-proof tank 1, and the water seal flame arrester floating plate 21 can be slidably sleeved on one end of the air intake elbow 11.

[0027] By adopting the above technical solution, the gas enters the water in the explosion-proof tank 1 through the air intake elbow 11.

[0028] An outlet pipe 12 is fixedly installed on the side of the water-sealed flame arrester explosion-proof tank 1 away from the air inlet elbow 11, and the air outlet pipe 12 is connected to the interior of the explosion-proof tank 1. A fire-blocking core 13 is fixedly installed inside the water-sealed flame arrester air inlet elbow 11 and the air outlet pipe 12, and a plurality of air holes distributed in an annular manner are opened on the two water-sealed flame arrester fire-blocking cores 13.

[0029] By adopting the above technical solution, the gas is discharged through the outlet pipe 12. When a fire occurs in the air inlet elbow 11 and the air outlet pipe 12, the flame passes through the fire-blocking core 13 to form many small flame flows. Due to the large heat transfer area of ​​the channel, the flame exchanges heat through the channel wall and the temperature drops. When it reaches a certain level, the flame can be extinguished.

[0030] A liquid level gauge 16 is fixedly mounted on one side of the explosion-proof tank 1 of the water-sealed flame arrester on which the air outlet pipe 12 is mounted, and the liquid level gauge 16 is connected to the interior of the explosion-proof tank 1 , and the liquid level gauge 16 of the water-sealed flame arrester is made of transparent material.

[0031] By adopting the above technical solution, the liquid level meter 16 is used to facilitate observation of the water level inside the explosion-proof tank 1 .

[0032] An explosion-proof cover 15 is fixedly installed on the top of the water-sealed flame arrester explosion-proof tank 1, and four rollers 17 distributed in an annular manner are rotatably installed on the bottom of the water-sealed flame arrester explosion-proof tank 1.

[0033] By adopting the above technical solution, the roller 17 is used to facilitate the movement of the entire device.

[0034] Working principle: When the utility model is in use, the gas enters the water in the explosion-proof tank 1 through the air inlet elbow 11, then precipitates from the water and is discharged through the air outlet pipe 12. The water in the explosion-proof tank 1 forms a water seal state for the air inlet elbow 11 and the air outlet pipe 12. When an explosion occurs at one end, a continuous explosion cannot be formed under the isolation of the water seal. However, when the gas enters the water through the air inlet elbow 11, more bubbles will be generated, resulting in frequent fluctuations in the liquid level. At this time, the floating plate 21 in the explosion-proof tank 1 will stabilize the liquid level. The gas in the water is precipitated out of the water through the fixed holes 22 on the floating plate 21, and the floating plate 21 will also rise and fall with the rise and fall of the water level in the explosion-proof tank 1 (the default water level is the normal height). When the floating plate 21 rises and falls, it will drive the fixed rod 31 to rise and fall. When a fire explosion occurs in the air inlet elbow 11 and the air outlet pipe 12, the flame passes through the fire-blocking core 13, forming many small flame flows. Due to the large heat transfer area of ​​the channel, the flame exchanges heat through the channel wall, and the temperature drops. When it reaches a certain level, the flame can be extinguished.

[0035] An external water source is connected to inject water into the explosion-proof tank 1 through the water injection pipe 18. As the water level rises, the floating plate 21 in the explosion-proof tank 1 rises, and the floating plate 21 drives the fixed rod 31 to rise. When the water level in the explosion-proof tank 1 reaches a specified height, the first tooth plate 32 on the fixed rod 31 drives the first valve 181 on the water injection pipe 18 to rotate until it is closed. At the same time, the second tooth plate 33 on the fixed rod 31 drives the second valve 191 on the drain pipe 19 to rotate and open, and the water inside the explosion-proof tank 1 will be discharged through the drain pipe 19. When the water level in the explosion-proof tank 1 drops to a specified height, the floating plate 21 drives the liquid level control component 3 to move in a trajectory opposite to the above description, so that the first tooth plate 32 on the fixed rod 31 drives the first valve 181 on the water injection pipe 18 to rotate and open, and at the same time, the second tooth plate 33 on the fixed rod 31 drives the second valve 191 on the drain pipe 19 to rotate until it is closed, so that the water level inside the explosion-proof tank 1 always maintains a suitable height (the buoyancy and deadweight of the floating plate 21 can drive the fixed rod 31 to push the valve to rotate).

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
