Technical Field

[0001] This utility model relates to the technical field of natural gas drying, specifically a natural gas drying device with dehydration function. Background Technology

[0002] A natural gas drying unit is a device that uses the adsorption force of molecular sieves to dry and purify natural gas. It is widely used in various stages of natural gas extraction, transportation, and refueling.

[0003] For example, utility model patent CN212222893U includes a base and a tank. The outer surface of the tank is covered with an outer shell. An air inlet pipe is fixedly connected to the lower side of the tank, and an air outlet pipe is fixedly connected to the upper end of the tank. A thermometer is fixedly connected to the outer surface of the air outlet pipe. A sampling tube is fixedly connected to the upper front end of the tank. Two sets of mesh plates are fixedly installed inside the tank. Molecular sieves are filled between the two sets of mesh plates inside the tank.

Detailed Implementation

[0024] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] This utility model proposes a natural gas drying device with dehydration function, comprising:

[0026] Casing 1;

[0027] A movable plate is provided at the bottom of the housing 1. Two pairs of support rods are fixedly installed on the upper end face of the movable plate. The top of the support rods is fixedly connected to the lower end face of the housing 1 to support the housing 1 and keep it stable. At the same time, two pairs of universal wheels are rotatably installed on the lower end face of the movable plate to facilitate the transportation of the housing 1. An air inlet pipe is fixedly connected to the lower end of one side wall of the housing 1 to facilitate the entry of natural gas into the housing 1. An air outlet pipe is fixedly connected to the upper wall of the housing 1 to facilitate the discharge of natural gas from the housing 1. At the same time, a thermometer is fixedly installed on the outer surface of the housing 1 to detect the temperature inside the housing 1.

[0028] The supporting frame 2 is fixedly installed on the inner wall of the housing 1;

[0029] Fixed frame 3 is located on the upper surface of the supporting frame 2;

[0030] The supporting frame 2 can support the fixed frame 3, keeping its position stable within the housing 1;

[0031] The support net 4 is fixedly installed inside the fixed frame 3;

[0032] The fixing plate 5 is fixedly installed inside the fixing frame 3 and is located above the supporting net 4;

[0033] Molecular sieve 6 is located between the supporting mesh 4 and the fixed plate 5;

[0034] Molecular sieve 6 is filled between fixed plate 5 and support mesh 4, which can adsorb moisture in natural gas entering the shell 1 through the inlet pipe;

[0035] Opening 7 is formed within the fixing plate 5;

[0036] Protective netting 8 is fixedly installed inside the opening 7;

[0037] The protective net 8 can restrict the molecular sieve 6 and prevent it from flowing out of the opening 7. At the same time, the natural gas adsorbed by the molecular sieve 6 can flow out of the opening 7 and be discharged through the gas outlet pipe.

[0038] The receiving port 9 is formed inside one side wall of the shell 1;

[0039] The collection port 9 allows the fixed frame 3 to be easily removed from the housing 1, facilitating the replacement of the molecular sieve 6;

[0040] The sealing plate 10 is fixedly installed on one side wall of the housing 1 to seal the collection port 9;

[0041] The sealing plate 10 is equipped with bolts, which are threadedly connected to the housing 1 to seal the collection port 9 and prevent natural gas inside the housing 1 from leaking out through the collection port 9.

[0042] Specifically, a placement opening 11 is formed inside the fixing plate 5, and a flip plate 12 for sealing the placement opening 11 is hinged to the upper end face of the fixing plate 5.

[0043] The placement port 11 allows workers to easily fill the space between the fixed plate 5 and the supporting net 4 with molecular sieve 6 or remove the molecular sieve 6 for easy replacement. At the same time, the flip plate 12 can seal the placement port 11 to prevent the molecular sieve 6 from overflowing from the placement port 11.

[0044] Specifically, a cavity 13 is formed in the side wall of the housing 1, an inlet pipe 14 communicating with the cavity 13 is fixedly installed on the upper surface of the outer surface of the housing 1, an outlet pipe 15 communicating with the cavity 13 is fixedly installed on the lower end face of the housing 1, and a valve 16 is fixedly installed on the outlet pipe 15.

[0045] Under the action of the inlet pipe 14, external coolant can be added into the cavity 13 to cool the space inside the shell 1. At the same time, under the action of the outlet pipe 15 and the valve 16, the coolant in the cavity 13 can be discharged for recycling and reuse.

[0046] Specifically, a first sealing gasket 17 is adhered to the outer wall of the fixed frame 3, and the surface of the first sealing gasket 17 is in contact with the inner wall of the housing 1.

[0047] Under the action of the first sealing gasket 17, the gap between the fixed frame 3 and the inner wall of the housing 1 can be sealed, preventing natural gas from flowing from the gap to the top of the fixed frame 3, which can improve the drying quality of natural gas.

[0048] Specifically, a second sealing gasket 18 is adhered to one end face of the sealing plate 10, and one end face of the second sealing gasket 18 is in contact with the outer surface of the housing 1.

[0049] The second sealing gasket 18 can improve the sealing quality of the receiving port 9 and prevent natural gas leakage.

[0050] Working principle: In actual use, natural gas is first delivered into the housing 1 through the inlet pipe. At this time, the molecular sieve 6 can adsorb the moisture in the natural gas. The adsorbed natural gas flows upward through the outlet 7 and is discharged through the outlet pipe. When the molecular sieve 6 needs to be replaced after long-term use, first turn the bolt to remove the sealing plate 10 and open the collection port 9. Then, lift the fixed frame 3 upward and take it out through the collection port 9. After taking it out, flip the flip plate 12 to open the placement port 11. Then, tilt the fixed frame 3 to pour out the molecular sieve 6 inside. After pouring out, add new molecular sieve 6 into the fixed frame 3 through the placement port 11. The sub-sieve 6 is flipped and the flipping plate 12 is turned over to seal the placement port 11. At this time, the fixing frame 3 with the collection port 9 is placed back into the housing 1 and placed on the bearing frame 2 to keep it stable. At the same time, the sealing plate 10 is fixedly connected to the housing 1 with bolts to seal the collection port 9. When the temperature gauge detects that the temperature inside the housing 1 is high, external coolant can be added to the cavity 13 through the liquid inlet pipe 14 to cool the side wall of the housing 1 and the space inside the housing 1. At the same time, under the action of the liquid outlet pipe 15 and the valve 16, the coolant can be discharged to the outside for easy recycling and reuse, bringing convenience to people.
