Description

TECHNICAL FIELD

[0001] The utility model relates to sealed water pressure relief recovery technical field, concretely relates to an open steam water separator. BACKGROUND

[0002] In the natural gas purification station of the oilfield gas production plant, the sulfur recovery device is responsible for converting sulfides in natural gas into solid sulfur cake, thereby effectively removing harmful substances in natural gas. However, in the production process of sulfur cake, the dehydration treatment of sulfur cake, this step usually relies on a vacuum pump to achieve. The vacuum pump forms sealed water by extracting water in the sulfur cake in the form of steam-water mixture to achieve the purpose of dehydration by applying negative pressure.

[0003] When the sealed water is discharged, it is usually a steam-water mixture at about 50 DEG C and has a certain pressure, about 0.02Mpa. In order to release the pressure accumulated in the recovery tank and prevent it from exceeding the safety threshold, the outlet pipeline of the sealed water is a three-way structure, one end is connected to the atmosphere for releasing pressure, and the other end is connected to the recovery tank for returning the sealed water into the tank.

[0004] When the sealed water releases pressure through the three-way pipeline, due to the characteristics of the steam-water mixture, a large amount of steam and water are often sprayed out from the pipeline end connected to the atmosphere. This phenomenon causes serious water accumulation in the production site, which poses a safety hazard to workers. Long-term water accumulation can cause surrounding equipment to rust faster due to moisture, thereby shortening the service life of the equipment, increasing maintenance costs, and even causing more serious production accidents. INVENTION CONTENTS

[0005] The utility model intends to provide an open steam water separator to solve the technical problem that water is easily sprayed out of the pressure relief port in the recovery and pressure relief process of sealed water in the prior art, causing water accumulation outside the pressure relief port.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an open steam water separator, comprising a cylindrical cylinder, a rectifier component, a drain pipe and a recovery water tank;

[0007] The cylindrical cylinder is open at the upper end, the water outlet of the drain pipe extends into the cylindrical cylinder from the upper end of the cylindrical cylinder, and the recovery water tank is in communication with the bottom of the cylindrical cylinder; the rectifier component is arranged at the water outlet of the drain pipe, the rectifier component is a pipe segment with one end closed and one end open, the open end of the rectifier component is in communication with the water outlet of the drain pipe, and the pipe body of the rectifier component is provided with a group of sieve holes for steam and water to pass through;

[0008] The rectifying component is further provided with a first blocking plate extending outward in the circumferential direction, which is located above the screen hole group; the inner wall of the cylindrical barrel is provided with a second blocking plate extending inward in the circumferential direction, which is located above the first blocking plate; a gap is left between the first blocking plate and the inner wall of the cylindrical barrel, and a gap is left between the second blocking plate and the drain pipe.

[0009] The principle and advantages of the present scheme are as follows: in actual application, when the steam-water mixture enters the open steam-water separator through the drain pipe, it first enters the rectifying component. The rectifying component enables the steam-water mixture to be uniformly dispersed and sprayed into the cylindrical barrel. The steam-water can be sprayed out through the screen holes at a small pressure and speed, avoiding direct high-pressure spraying.

[0010] After the steam-water mixture enters the cylindrical barrel, it first contacts the inner wall of the cylindrical barrel and is subjected to the first buffering deceleration. Due to the action of gravity, the water in the steam-water mixture begins to sink, while the gas part continues to rise. The first blocking plate is located above the screen hole group, which can further block and disperse the steam-water, preventing the steam-water from directly impacting the upper part of the cylindrical barrel, thereby reducing the possibility of water in the steam-water mixture being carried by the gas and sprayed out. As the steam-water rises, the second blocking plate further blocks and disperses the steam-water. A gap is left between the second blocking plate and the drain pipe, allowing the gas to pass through but effectively slowing down the speed of the gas, so that more water can be settled. Finally, the water flows into the water recovery tank through the cylindrical barrel under the action of gravity, while the gas is discharged through the upper opening of the cylindrical barrel, effectively solving the problem of water accumulation outside the pressure relief port.

[0011] Compared with the existing filtering and water absorbing methods, the present device enables the steam-water to be rapidly dispersed and settled, which improves the pressure relief speed and reduces the maintenance cost of the equipment, as no consumables need to be replaced regularly. The device has a simple structure, which reduces the manufacturing, installation, and maintenance costs.

[0012] As an improvement, the inner side of the second blocking plate is provided with a through central hole, the axis of the central hole overlaps the axis of the drain pipe, and the diameter of the first blocking plate is greater than the diameter of the central hole of the second blocking plate.

[0013] The beneficial effects of the improvement are as follows: after the steam-water mixture passes through the rectifying component, it will not be directly sprayed out of the cylindrical barrel through the central hole of the second blocking plate. Since the diameter of the first blocking plate is greater than the diameter of the central hole of the second blocking plate, the steam-water mixture will be forced to disperse and flow along the inner wall of the cylindrical barrel after being blocked by the first blocking plate, further contacting the inner wall and decelerating. In this way, more water can be settled, while the gas rises and is discharged through the gap between the second blocking plate and the cylindrical barrel. This design effectively prevents the steam-water mixture from being directly sprayed out of the cylindrical barrel, reducing the risk of water accumulation outside the pressure relief port.

[0014] As an improvement, the second blocking plate is downwardly inclined from the outer edge to the inner edge.

[0015] The improvement has the beneficial effect that, since the temperature of the steam-water is higher than the room temperature, the steam-water will be subjected to transpiration during the rising process. The second blocking plate is designed to be downwardly inclined from the outer edge to the inner edge, so that the steam-water will be detained below the second blocking plate after contacting the second blocking plate, further reducing the temperature and speed. This design helps to increase the contact area and time of the steam-water with the second blocking plate, thereby improving the settling efficiency of the steam-water. At the same time, the inclined design also helps to guide the water flow along the inner wall of the cylindrical barrel into the recovery water tank, further reducing the possibility of water accumulation outside the pressure relief port.

[0016] As an improvement, the screen hole group includes multiple rows of screen holes uniformly distributed along the axial direction of the flow regulating component, and each row of screen holes includes multiple screen holes uniformly distributed along the circumferential direction of the flow regulating component; the number of rows of screen holes is greater than or equal to 3, and the number of screen holes in each row is greater than or equal to 8.

[0017] The improvement has the beneficial effect that the design of the screen hole group allows the steam-water mixture to be more evenly dispersed and injected into the cylindrical barrel. The multiple rows of uniformly distributed screen holes ensure that the steam-water mixture is sufficiently dispersed and slowed down within the flow regulating component, thereby reducing the risk of the steam-water mixture being directly injected out of the cylindrical barrel. In addition, the number of screen holes in each row is greater than or equal to 8 to ensure uniform dispersion of the steam-water mixture. This design improves the efficiency of steam-water separation and further reduces the possibility of water accumulation outside the pressure relief port.

[0018] As an improvement, the diameter of each screen hole is ≤0.785×R α , R α is the pipe radius of the flow regulating component.

[0019] The improvement has the beneficial effect that it ensures that the opening area of the screen hole is moderate, allowing the steam-water mixture to smoothly enter the cylindrical barrel through the screen hole while avoiding the problem of the steam-water mixture being directly injected out of the cylindrical barrel due to excessively large screen holes.

[0020] As an improvement, the second blocking plate forms a 10° angle with the inner wall of the cylindrical barrel.

[0021] The improvement has the beneficial effect that it ensures that the steam-water can smoothly rise and exit through the gap between the second blocking plate and the cylindrical barrel, avoiding the problem of steam-water accumulation within the cylindrical barrel. BRIEF DESCRIPTION OF DRAWINGS

[0022] Figure 1 is a structural schematic diagram of an embodiment of the present utility model. DETAILED DESCRIPTION

[0023] The following will be further described in detail through specific embodiments:

[0024] The reference numerals in the accompanying drawings include: cylindrical body 1, rectifier component 2, first baffle plate 3, second baffle plate 4, drain pipe 5, recovery water tank 6, and sieve hole 7.

[0025] Example

[0026] The basics are as follows: Figure 1 As shown, the sealing water is drawn from the vacuum pump through the drain pipe 5. The sealing water in the drain pipe 5 is in a steam-water mixture state, and the steam-water mixture has a pressure of about 0.02 MPa. This embodiment discloses an open steam-water separator that depressurizes the steam-water mixture and recovers the sealing water at the same time.

[0027] The open-type steam-water separator includes a cylindrical body 1, a rectifier 2, a first baffle plate 3, a second baffle plate 4, a drain pipe 5, and a recovery water tank 6.

[0028] A cylindrical body 1 is located between the drain pipe 5 and the recovery water tank 6. The cylindrical body 1 is open at the top. The drain pipe 5 extends into the cylindrical body 1 from the top. The recovery water tank 6 is located below the cylindrical body 1 and is connected to it. A flow rectifying component 2 is provided at the outlet of the drain pipe 5. The flow rectifying component 2 is a pipe section that is closed at one end and open at the other end. The open end of the flow rectifying component 2 is connected to the outlet of the drain pipe 5 that extends into the cylindrical body 1.

[0029] The rectifier component 2 has a screen hole group on its tube body. The screen hole group includes multiple rows of screen holes evenly distributed along the axial direction of the rectifier component 2. Each row of screen holes includes multiple screen holes 7 evenly distributed along the circumference of the rectifier component 2. The diameter of a single screen hole 7 is ≤0.785×R. α R α The radius of the rectifier component 2 is given. The number of rows of sieve holes 7 is greater than or equal to 3, and the number of sieve holes in a single row is greater than or equal to 8. In this embodiment, the number of sieve holes 7 is 3 rows, with 8 holes per row.

[0030] The rectifier 2 is also provided with a first baffle plate 3 extending outward in the circumferential direction, located between the sieve group and the open end of the rectifier 2. The inner wall of the cylindrical body 1 is provided with a second baffle plate 4 extending inward in the circumferential direction, located above the first baffle plate 3. A gap is left between the first baffle plate 3 and the inner wall of the cylindrical body 1, and a gap is left between the second baffle plate 4 and the drain pipe 5. The inner side of the second baffle plate 4 has a through-hole, the axis of which overlaps with the axis of the drain pipe 5. The diameter of the first baffle plate 3 is larger than the diameter of the central hole of the second baffle plate 4.

[0031] The side of the second baffle plate 4 that is fixedly connected to the cylindrical body 1 is higher than the side of the second baffle plate 4 with the central hole, and the second baffle plate 4 is inclined downward from the outer edge to the inner edge. The second baffle plate 4 forms a 10° angle with the inner wall of the cylindrical body 1.

[0032] The implementation process is as follows:

[0033] The steam-water mixture filtered by the vacuum pump is led out by the drain pipe 5, and the steam-water mixture enters the rectifying part 2 along the drain pipe 5, and the steam-water mixture is sprayed out from the screen holes 7 in all directions, and the steam-water mixture directly acts on the inner wall of the cylindrical barrel 1 to obtain the first buffering. The flow rate and pressure of the steam-water mixture are effectively reduced, and the water flows into the recovery water tank 6 connected at the bottom of the cylindrical barrel 1 under the action of gravity. At the same time, the steam-water mixture cannot be sprayed on the upper end of the cylindrical barrel 1 by the straight-line path due to the shielding of the first blocking plate 3 and the second blocking plate 4, so as to avoid the steam-water mixture sprayed directly from the screen holes 7 from splashing out of the cylindrical barrel 1.

[0034] Since the temperature of the steam-water mixture output by the vacuum pump is higher than the room temperature, the steam-water mixture sprayed from the screen holes 7 is dissipated to the top of the cylindrical barrel 1 under the cooling transpiration effect. When the steam-water mixture rises and hits the second blocking plate 4, the second blocking plate 4 performs the second pressure reduction and speed reduction on the steam-water mixture, and then the second blocking plate 4 is inclined downward, and most of the steam-water mixture will be temporarily detained below the second blocking plate 4. The detained steam-water mixture is affected by the temperature and the flow rate, and becomes condensed water flowing to the recovery tank. A small part of the steam-water mixture that has been effectively cooled and reduced in speed is dissipated to the outside from the top end of the cylindrical barrel 1, and this part of the steam-water mixture will not generate water accumulation near the outlet, and will not affect the service life of the surrounding equipment.

[0035] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
