Abstract
Description
TECHNICAL FIELD
[0001] The application relates to the technical field of water drainers, in particular to a self-closing coal gas water drainer capable of preventing breakage. BACKGROUND
[0002] In the production and conveying process of metallurgical coal gas, a coal gas water drainer is an important safety device in a coal gas pipeline. The working principle of the coal gas water drainer is that a water drain pipe at the lower part of the coal gas pipeline is sealed by a water seal with a certain height, so that the coal gas is not leaked and the condensed water in the coal gas pipeline can be drained. In this process, the coal gas pipeline system must maintain a certain positive pressure to meet the requirements of safe conveying and user use.
[0003] A traditional coal gas water drainer increases the water pressure head by arranging multiple water tanks to achieve a sealing effect. When a coal gas production unit and a use unit have a significant load change, the pressure of the coal gas pipeline network will change instantaneously. When the pressure is greater than the total pressure head of the water drainer, multiple coal gas water drainers of the pipeline network will be broken instantaneously, causing a large amount of coal gas leakage. Therefore, an operator needs to restore the water supply of the water drainer one by one, which is low in accident handling efficiency and high in danger. CONTENT OF THE INVENTION
[0004] The purpose of the application is to provide a self-closing coal gas water drainer capable of preventing breakage, which improves the sealing effect by adopting a multi-stage sealing mode and avoids coal gas leakage of the pipeline network.
[0005] The application provides a self-closing coal gas water drainer capable of preventing breakage, which adopts the following technical solutions.
[0006] The self-closing coal gas water drainer capable of preventing breakage comprises a sealing water tank and an overflow cylinder. The upper end of the sealing water tank is provided with a condensed water pipe and a water supply pipe. The water supply pipe is provided with a water supply valve. The side upper end of the sealing water tank is provided with a water drain pipe. The inside of the sealing water tank is provided with a first partition plate and a second partition plate. The first partition plate and the second partition plate divide the inside of the sealing water tank into a first tank body, a second tank body and a third tank body. The condensed water pipe and the water supply pipe are located at the upper end of the first tank body. The upper end of the first partition plate is provided with a first overflow hole. The upper end of the second partition plate is provided with a second overflow hole. The overflow cylinder is fixedly arranged in the third tank body. The overflow cylinder is communicated with the water drain pipe. The lower end of the overflow cylinder is provided with a third overflow hole. The inside of the overflow cylinder is provided with a float. The lower end of the float is provided with a sealing plug. The sealing plug is used for plugging the third overflow hole.
[0007] Preferably, the upper end of the overflow cylinder penetrates the sealing water tank. The upper end of the float is provided with an indication mark. The indication mark extends to the outside of the overflow cylinder.
[0008] Preferably, the cross section of the overflow cylinder is rectangular structure, and the inner wall of the overflow cylinder is provided with a rib plate, and the number of the rib plate is 2-4.
[0009] Preferably, the upper end of the sealed water tank is provided with an exhaust pipe, and the exhaust pipe is provided with an exhaust valve.
[0010] Preferably, the inside of the sealed water tank is provided with a liquid level sensor, and the liquid level sensor is located in the first tank body.
[0011] Preferably, the lower end of the sealing plug is in the shape of a neck.
[0012] Preferably, the outside of the sealed water tank is provided with a heat preservation layer.
[0013] Preferably, the float is a hollow structure and is made of stainless steel material.
[0014] Preferably, the sealing plug is made of corrosion-resistant rubber material.
[0015] Compared with the prior art, the application has the beneficial effects that:
[0016] The first partition plate and the second partition plate separate the inside of the sealed water tank into the first tank body, the second tank body and the third tank body, and the first overflow hole is arranged on the first partition plate and the second overflow hole is arranged on the second partition plate, so that a three-stage water seal is formed. In normal operation, the inside of the first tank body, the second tank body and the third tank body is filled with water. With the continuous discharge of the condensed water into the inside of the sealed water tank, the water in the third tank body continuously enters the inside of the overflow cylinder through the third overflow hole. Under the action of the buoyancy, the float is in a floating state. The condensed water enters the drain pipe through the gap between the float and the overflow cylinder and is discharged through the drain pipe. When the water seal is broken, the water in the first tank body, the second tank body and the third tank body is discharged. Under the action of the gravity, the float moves downward, so that the sealing plug is tightly combined with the third overflow hole, thereby playing a role of sealing the coal gas, so that the leakage of the pipe network gas is avoided.

[0031] Example
[0032] like Figures 1-5 As shown in the embodiment of this application, the anti-breakage self-closing gas drain includes a sealed water tank 1 and an overflow cylinder 2. A condensate pipe 3 and a water supply pipe 4 are provided at the upper end of the sealed water tank 1. A water supply valve 5 is provided on the water supply pipe 4. A drain pipe 6 is provided at the upper side of the sealed water tank 1. A first partition 7 and a second partition 8 are provided inside the sealed water tank 1, dividing the interior of the sealed water tank 1 into a first compartment 9, a second compartment 10, and a third compartment 11. The condensate pipe 3... Both the water supply pipe 4 and the water replenishment pipe 4 are located at the upper end of the first chamber 9. The upper end of the first partition 7 is provided with a first overflow hole 12, and the upper end of the second partition 8 is provided with a second overflow hole 13. The overflow cylinder 2 is fixed in the third chamber 11 and is connected to the drain pipe 6. The lower end of the overflow cylinder 2 is provided with a third overflow hole 14. The inside of the overflow cylinder 2 is provided with a float 15. The density of the float 15 is less than that of water. The lower end of the float 15 is provided with a sealing plug 16, which is used to seal the third overflow hole 14.
[0033] In use, the first compartment 9, the second compartment 10, and the third compartment 11 are all filled with water. Condensate is continuously discharged into the first compartment 9 through the condensate pipe 3. Under the action of buoyancy, the float 15 is in a floating state. Condensate enters the drain pipe 6 through the gap between the float 15 and the overflow pipe 2 and is discharged through the drain pipe 6. When the water seal is broken, the water inside the first compartment 9, the second compartment 10, and the third compartment 11 is discharged. The float 15 moves downward under the action of gravity, so that the sealing plug 16 is tightly connected with the third overflow hole 14, which plays the role of sealing the gas and thus preventing gas leakage from the pipeline network.
[0034] In this embodiment, the upper end of the overflow cylinder 2 penetrates the sealed water tank 1, and the upper end of the float 15 is provided with an indicator 17. The indicator 17 extends to the outside of the overflow cylinder 2. When in use, the staff can observe the indicator 17 from the outside to determine the position of the float 15.
[0035] In this embodiment, the overflow cylinder 2 has a rectangular cross-section and ribs 18 are provided on the inner wall of the overflow cylinder 2. The number of ribs 18 is 2-4. The ribs 18 play a guiding role during the lifting and lowering of the float 15, thereby ensuring accurate alignment between the sealing plug 16 and the third overflow hole 14.
[0036] In this embodiment, an exhaust pipe 19 is provided at the upper end of the sealed water tank 1, and an exhaust valve 20 is provided on the exhaust pipe 19. When the gas pressure in the pipeline is lower than the set value, the exhaust valve 20 is opened, and the gas in the sealed water tank 1 can return to the pipeline, thereby realizing the recovery of gas.
[0037] In this embodiment, a liquid level sensor 21 is installed inside the sealed water tank 1. The liquid level sensor 21 is located inside the first tank body 9. The liquid level sensor 21 is used to detect the liquid level inside the first tank body 9, so that the staff can replenish water to the inside of the first tank body 9 in a timely manner.
[0038] In this embodiment, the lower end of the sealing plug 16 is constricted. The constricted structure can improve the sealing effect of the sealing plug 16 on the third overflow hole 14 and also play a guiding role.
[0039] In this embodiment, an insulation layer 22 is provided on the outside of the sealed water tank 1. The insulation layer 22 is used to prevent the loss of heat inside the sealed water tank 1.
[0040] In this embodiment, the float 15 is made of hollow stainless steel. The stainless steel material can prevent the float 15 from rusting due to long-term immersion in water, thereby extending the service life of the float 15.
[0041] In this embodiment, the sealing plug 16 is made of corrosion-resistant rubber material. The corrosion-resistant material can prevent the sealing plug 16 from being corroded, thereby extending the service life of the sealing plug 16.
[0042] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
