Description

Technical Field

[0001] This invention relates to the field of drainage operation technology, and more specifically to a device for collecting accumulated liquid in equipment at non-sulfur-containing well stations. Background Technology

[0002] In the daily production of non-sulfur-containing well stations, it is necessary to regularly drain the liquid from equipment such as orifice flow meters and separator level gauges. The traditional method uses unsealed buckets or basins to collect gas and liquid. When the control valve is opened, due to the pressure inside the equipment, the gas and liquid flow rate is too fast, and the liquid in the pipe splashes out with the airflow, which can easily cause environmental pollution and poses certain safety risks. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a device for collecting accumulated liquid in equipment at non-sulfur-containing well stations. The device has a simple structure, is easy to operate, has a high success rate in loading and unloading, and can adapt to various types of drain valves and production processes of various pressure levels, making it highly applicable.

[0004] To solve the above-mentioned technical problems, the technical solution proposed by this invention is as follows:

[0005] A device for collecting accumulated liquid in equipment at a non-sulfur-containing well station includes a connector and a closed cylinder. The connector is used to connect to the interface of the drain valve of the non-sulfur-containing well station equipment, and the connector and the cylinder are connected to each other through a connecting pipe. An exhaust port is provided on the cylinder near the top, and a control valve for controlling the drain is provided on the cylinder near the bottom.

[0006] According to the present invention, the equipment liquid collection device for non-sulfur-containing well stations adopts various types of connectors according to the specifications of the drain valve, which has the characteristics of convenient mutual conversion. It is suitable for liquid drainage of various level gauges, filters, orifice valve instruments and orifice valve chambers. The liquid is collected in a relatively closed cylinder, and the gas in the cylinder is discharged in time through the exhaust port, which effectively balances the pressure in the cylinder and does not cause pollution to the external environment. This enhances the environmental protection function of the device and improves the safety index when workers are performing liquid drainage operations.

[0007] The above technical solution can be further improved as described below.

[0008] In a preferred embodiment of the equipment liquid collection device for non-sulfur-containing well stations according to the present invention, a gas-liquid separation mechanism is provided inside the cylinder.

[0009] The gas-liquid separation mechanism can effectively separate gas and liquid, collect the liquid inside the cylinder, and discharge the gas through the exhaust port, thereby further ensuring the safety and environmental friendliness of the liquid discharge.

[0010] Specifically, in a preferred embodiment, the gas-liquid separation mechanism includes a partition and a filter screen. The partition is arranged vertically inside the cylinder to divide the inside of the cylinder into two chambers. One chamber is connected to the outlet of a connecting pipe, and the other chamber is connected to an exhaust port and a control valve, respectively. Filter screens are provided in both chambers, and flow holes are provided at intervals on the partition near the downward position of the filter screen.

[0011] Specifically, the gas-liquid separation mechanism uses a filter screen to separate gas and liquid based on their density. During discharge, the gas and liquid enter one side chamber of the cylinder through a high-pressure hose. When the gas and liquid pass through the filter screen in this chamber, the filter screen acts as a damper, buffer, and filter. The liquid phase then sinks and separates from the gas phase, passing through the flow holes of the partition into the other side chamber. The gas phase rises and is further separated by the filter screen. The remaining liquid phase is then discharged from the cylinder through the exhaust port. All liquid phases are deposited at the bottom of the cylinder, thus effectively collecting the liquid at the bottom of the entire cylinder.

[0012] Furthermore, in a preferred embodiment, the filter screen located in the chamber communicating with the outlet of the connecting pipe is arranged in a downwardly inclined manner.

[0013] The above arrangement can effectively increase the filtration area of ​​the filter screen, thereby greatly improving the gas-liquid separation effect.

[0014] Furthermore, in a preferred embodiment, a liquid level measuring device is provided on one side of the outer side of the cylinder.

[0015] Manual observation of liquid collection within the cylinder can be conducted using a liquid level measuring device to determine the degree of liquid accumulation and, depending on the situation, decide whether to open the control valve to drain the liquid.

[0016] Specifically, in a preferred embodiment, the connector employs a union and a parallel tee connection.

[0017] The above-described connector structure effectively improves the ease of connector replacement and installation, thereby enhancing the overall applicability of the collection device.

[0018] Specifically, in a preferred embodiment, the connecting pipe is a flexible hose made of rubber.

[0019] It uses a high-pressure hose, which has high pressure resistance and is soft in texture, making it highly safe and easy to operate in actual operation.

[0020] Furthermore, in a preferred embodiment, a flange is provided at the top of the cylinder to achieve closure, and a telescopic handle is provided on the flange, through which the connecting pipe is connected to the cylinder.

[0021] Manual cleaning or replacement of the filter screen inside the cylinder can also be achieved by unscrewing the flange bolts and removing the flange. While ensuring the weight of the cylinder itself, a telescopic handle is provided to facilitate dragging the cylinder and reduce manual effort during operation.

[0022] Furthermore, in a preferred embodiment, the bottom of the cylinder is provided with a support and casters.

[0023] Before use, the device can be easily and labor-savingly dragged to the work site by using casters, reducing manual labor, and the support structure can effectively increase the structural stability and reliability of the entire device.

[0024] Specifically, in a preferred embodiment, the control valve is a drain ball valve.

[0025] The drain ball valve can be manually controlled to promptly drain the accumulated liquid inside the cylinder, which can improve the practicality of the entire draining device for continuous operation.

[0026] Compared with the prior art, the advantages of this invention are: simple structure, convenient operation, high success rate of loading and unloading, adaptability to various types of drain valves and production processes of various pressure levels, strong applicability, no pollution to the external environment, enhanced environmental protection function of the device, and improved safety index when manual draining operations are performed.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection of the present invention.

[0031] Figure 1 The schematic diagram illustrates the overall structure of the equipment liquid collection device 10 for non-sulfur-containing well stations according to an embodiment of the present invention.

[0032] like Figure 1As shown, the equipment liquid collection device 10 for non-sulfur-containing well stations according to an embodiment of the present invention includes a connector 1 and a closed cylinder 2. The connector 1 is used to connect to the interface of the liquid discharge valve of the non-sulfur-containing well station equipment, and the connector 1 and the cylinder 2 are connected to each other through a connecting pipe 3. An exhaust port 21 is provided on the cylinder 2 near the top, and a control valve 4 for controlling the liquid discharge is provided on the cylinder 2 near the bottom.

[0033] According to embodiments of the present invention, the equipment liquid collection device for non-sulfur-containing well stations adopts various types of connectors according to the specifications of the drain valve, which has the characteristics of convenient mutual conversion. It is suitable for various liquid level gauge drains, filter drains, orifice valve instrument drains, and orifice valve chamber drains. The liquid is collected in a relatively closed cylinder. The cylinder is a normal pressure body, which can provide a sufficiently large gas-liquid separation space and liquid collection space. The gas in the cylinder is discharged in time through the exhaust port, effectively balancing the pressure in the cylinder and not causing pollution to the external environment. This enhances the environmental protection function of the device and improves the safety index when workers are performing liquid drainage operations.

[0034] like Figure 1 As shown, in this embodiment, a gas-liquid separation mechanism is provided inside the cylinder 2. This mechanism effectively separates the gas and liquid, collecting the liquid inside the cylinder while the gas is discharged through the exhaust port, thus further ensuring the safety and environmental friendliness of the liquid discharge.

[0035] Specifically, in this embodiment, the gas-liquid separation mechanism includes a partition 51 and a filter screen 52. The partition 51 is arranged vertically inside the cylinder 2, dividing the interior of the cylinder 2 into two chambers. One chamber is connected to the outlet of the connecting pipe 3, and the other chamber is connected to the exhaust port 21 and the control valve 4 respectively. Filter screens 52 are provided in both chambers, and flow holes 511 are provided at intervals near the downward position of the filter screens on the partition 51. Specifically, the gas-liquid separation mechanism can separate gas and liquid according to their different densities using the filter screens. During liquid discharge, gas and liquid enter one side chamber of the cylinder through a high-pressure hose. When the gas and liquid pass through the filter screen in this chamber, the filter screen provides damping, buffering, and filtering effects. The liquid phase sinks and separates from the gas phase, passing through the flow holes of the partition into the other side chamber. The gas phase rises and is further separated by the filter screen. The remaining liquid phase is then discharged from the cylinder through the exhaust port. All liquid phases are deposited at the bottom of the cylinder, thus effectively collecting the liquid at the bottom of the entire cylinder. Furthermore, in a preferred embodiment, the filter screen located in the chamber communicating with the outlet of the connecting pipe is arranged in a downwardly inclined manner. This arrangement effectively increases the filtration area of ​​the filter screen, thereby greatly improving the gas-liquid separation effect.

[0036] like Figure 1As shown, further, in this embodiment, a level gauge 6 is provided on one side of the exterior of the cylinder 2. A person can manually observe the liquid collection within the cylinder using the level measuring device, determine the degree of liquid accumulation, and decide whether to open the control valve to drain the liquid as needed.

[0037] Specifically, in this embodiment, connector 1 uses a union joint and a parallel tee connection. This type of connector structure effectively improves the ease of connector replacement and installation, thereby enhancing the overall applicability of the collection device. Specifically, in this embodiment, connecting pipe 3 is a flexible rubber hose. Using a high-pressure hose provides high pressure resistance, flexibility, and high safety and operability during actual operation. Specifically, in this embodiment, control valve 4 is a drain ball valve. The drain ball valve can be manually controlled to promptly drain accumulated liquid from the cylinder, improving the continuous operation practicality of the entire draining device.

[0038] like Figure 1 As shown, further, in this embodiment, a flange 7 is provided at the top of the cylinder 2 to achieve closure, and a telescopic handle 8 is provided on the flange. The connecting pipe 3 is connected to the cylinder 2 through the flange 7. The filter screen inside the cylinder can also be cleaned or replaced manually by opening the flange bolts to remove the flange. The telescopic handle is provided while ensuring the weight of the cylinder itself, making it convenient to drag the cylinder during operation and reducing manual effort.

[0039] like Figure 1 As shown, in this embodiment, the bottom of the cylinder 2 is provided with a bracket 9 and casters 101. Before use, the device can be easily and conveniently dragged to the work site by using the casters, reducing manual labor. Furthermore, the bracket structure can effectively increase the structural stability and reliability of the entire device.

[0040] Specifically, in this embodiment, preferably, the joint, the cylinder, and the partition are all made of 20# steel, wherein the cylinder is preferably (218~220)×(6~8)mm, and more preferably 219×7mm. The joint parameters are M(19~21)×(14~16) and R1 / 2, and more preferably M20×15 and R1 / 2.

[0041] Specifically, the method of using the equipment liquid collection device 10 for non-sulfur-containing well stations according to this embodiment of the invention is as follows:

[0042] Before use, the collection device 10 can be easily and labor-savingly dragged to the work site using the telescopic handle 8 and casters 101. It is then connected to the target drain valve interface via connector 1. During draining, the gas and liquid enter the right chamber of the cylinder 2 through the high-pressure hose. When the gas and liquid pass through the filter screen 52, the filter screen 52 acts as a damper, buffer, and filter, causing the liquid phase to sink and separate from the gas phase. It then enters the left chamber through the flow hole 511 of the partition 51. The gas phase rises and, after further separation by the filter screen 52, the remaining liquid phase is discharged from the cylinder 2 through the exhaust port 21. All liquid phases settle at the bottom of the cylinder 2. The operator can judge the degree of liquid accumulation in the cylinder 2 by observing the level gauge 6 and decide whether to open the drain ball valve to drain the liquid. The operator can also clean or replace the filter screen 52 inside the cylinder 2 by opening the flange bolts 7.

[0043] As can be seen from the above embodiments, the equipment liquid collection device for non-sulfur-containing well stations involved in this invention has a simple structure, is easy to operate, has a high success rate of loading and unloading, and can adapt to various types of drain valves and production processes of various pressure levels. It has strong applicability, does not cause pollution to the external environment, enhances the environmental protection function of the device, and improves the safety index of manual liquid drainage operations.

[0044] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
