Description

Technical Field

[0001] The utility model relates to the technical field of compressor detection, in particular to a gas field pressurization continuous production device. Background Art

[0002] During natural gas boosting and extraction, the existing process involves a single pipeline and filter at the compressor's inlet. After prolonged operation, the filter can easily become clogged by dust carried by the gas source, leading to increased pipeline differential pressure, insufficient compressor inlet pressure, and a low-pressure, high-temperature alarm. Failure to promptly detect excessive differential pressure can damage the filter, allowing gas containing impurities such as hydrates to enter the compressor, causing a malfunction and shutdown. Current preventative measures require shutting down the well to clean or replace the filter, resulting in unplanned downtime and production, severely impacting production schedules and increasing the risk of compressor failures. This also poses operational risks for employees who frequently start and stop large mechanical equipment. Utility Model Content

[0003] The utility model aims to provide a gas field pressurization continuous production device, which can realize the cleaning or replacement of the filter screen without stopping the compressor.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a gas field pressurization continuous production device, including a compressor, the compressor including an air inlet end, the air inlet end being connected to a filter assembly, the filter assembly including a first filter pipe and a second filter pipe connected in parallel, a first filter installed on the first filter pipe, a first and a second gate valve are installed on each side of the first filter, a second filter is installed on the second pipe, a third and a fourth gate valve are installed on each side of the second filter, a differential pressure data acquisition pipe is connected at both ends of the first and second parallel filter pipes, and a differential pressure flowmeter is installed on the differential pressure data acquisition pipe.

[0005] The principle of this solution is as follows: during use, only the first and second gate valves are opened, and the air flow enters the compressor through the first filter pipe, and the third and fourth gate valves are in the closed state; when an abnormal differential pressure value is detected, the third and fourth gate valves are opened, and the air flow enters the compressor through the second filter pipe, and the first and second gate valves are closed in time; and after the filter pipe is switched, the filter pipe with pipeline blockage is inspected, and the devices connected to the filter pipe are repaired, and the blocked devices, especially the filter, are replaced.

[0006] The advantages of this solution are: adding a bypass filter pipe to the original filter pipe of the compressor. When one of the filter pipes is blocked, it is switched to the new filter pipe in time. During the filter replacement process, the compressor does not need to stop working, which improves the equipment operation rate and reduces the failure shutdown caused by filter blockage.

[0007] If the filter screen on the filter pipe is clogged, it can be restored by cleaning and replacing it. At this time, the filter pipe remains closed and ready for activation. In addition, a differential pressure data acquisition pipe is connected to the two parallel filter pipes, and a differential pressure data collector is connected to the pipe to collect differential pressure data from both pipes simultaneously.

[0008] Preferably, the first filter pipe is provided with a first vent pipe connected to a vent valve, the vent pipe being located between the first and second gate valves, and the second filter pipe is provided with a second vent pipe connected to a second vent valve, the second vent valve being located between the third and fourth gate valves. When one of the filter pipes needs to be inspected and repaired, the gate valves on both sides of the filter are closed, and the gas-liquid mixture in the filter pipe is vented through the vent valve.

[0009] Preferably, the compressor further includes a vent interface, the vent interface is connected to a compressor vent pipe, and the first and second vent pipes are both connected to the compressor vent pipe.

[0010] Preferably, the first and second filter pipes are each independently equipped with a pressure gauge, and when emptying, it is possible to know whether there is any residual liquid by observing the pressure gauge.

[0011] Preferably, the first filter is connected to the first filter pipe at both ends by flanges, and the second filter is connected to the second filter pipe at both ends by flanges. When the filter needs to be replaced after long-term use, the entire filter can be removed by simply removing the flanges and then replacing it with a new filter.

[0012] Preferably, a lug for lifting the filter upward is provided at the joint of the first or second filter pipe for installing the filter. When installing the filter, the filter is temporarily pulled upward by the lug to avoid the problem of difficulty in aligning the flange connection hole during flange installation.

[0013] Finally, the first or second filter comprises a square housing with a removable sealing cover on top. The inner wall of the housing is provided with multiple parallel insertion slots flanked by T-shaped slots. Replaceable filter plates are inserted into these slots, and the edges of the filter plates are provided with T-shaped retaining edges that seal with the T-slots. The sealing cover can be opened regularly to replace the filter plates. This allows filter plates with heavy sediment to be cleaned and then replaced with cleaned filters without having to replace the filter housing, thus reducing the cost of disassembly and installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a structural diagram of the gas field pressurization continuous production device.

[0016] The following is further explained in detail through a specific embodiment. The figure numerals in the drawings of the specification include: compressor 1, first filter 2, embedded groove 21, filter plate 22, sealing cover plate 23, second filter 3, first gate valve 4, second gate valve 5, third gate valve 6, fourth gate valve 7, first vent valve 8, second vent valve 9, pressure gauge 10, compressor vent valve 11.

[0017] like Figure 1 As shown, a gas field pressurization continuous production device includes a compressor 1, the compressor 1 includes an air inlet end, the air inlet end is connected to a filter assembly, the filter assembly includes a first filter pipe and a second filter pipe connected in parallel, a first filter 2 is installed on the first filter pipe, a first gate valve 4 and a second gate valve 5 are installed on both sides of the first filter, a second filter 3 is installed on the second pipe, a third gate valve 6 and a fourth gate valve 7 are installed on both sides of the second filter 3, a differential pressure data acquisition pipe is connected to both ends of the parallel first and second filter pipes, and a differential pressure flowmeter 13 is installed on the differential pressure data acquisition pipe. Pressure gauges 10 are independently installed on the first and second filter pipes. When venting, by observing the pressure gauges, it can be known whether there is any residual liquid.

[0018] The first filter pipe is provided with a first vent pipe connected to a first vent valve 8, which is located between the first gate valve 4 and the second gate valve 5. The second filter pipe is provided with a second vent pipe connected to a second vent valve 9, which is located between the third gate valve 6 and the fourth gate valve 7. When one of the filter pipes needs to be repaired, the gate valves on both sides of the filter are closed, and the gas-liquid mixture in the filter pipe is vented through the vent valve.

[0019] The compressor 1 also includes a vent interface, which is connected to a compressor vent pipe. The first and second vent pipes are both connected to the compressor vent pipe. The compressor vent pipe is connected to a compressor vent valve 11. The first filter 2 is connected to the first filter pipe at both ends by flanges, and the second filter 3 is connected to the second filter pipe at both ends by flanges. A support ear for lifting the filter upward is provided at the joint of the first or second filter pipe where the filter is installed. When installing the filter, the filter is temporarily pulled upward by the support ear to avoid the problem of difficulty in aligning the flange connection hole during flange installation. When the filter is used for a long time, the entire filter needs to be replaced. The filter can be disassembled as a whole by simply disassembling the flange and replaced with a new filter.

[0020] During use, only the first and second gate valves are opened, and the airflow enters the compressor through the first filter pipe, while the third and fourth gate valves are closed. When an abnormal differential pressure value is detected, the third and fourth gate valves are opened, and the airflow enters the compressor through the second filter pipe, and the first and second gate valves are closed in time. After the filter pipe is switched, the filter pipe with pipeline blockage is inspected, and the components connected to the filter pipe are repaired and replaced with the blocked components, especially the filter. A bypass filter pipe is added to the original filter pipe of the compressor. When one of the filter pipes is blocked, it is switched to the new filter pipe in time. During the filter replacement process, the compressor does not need to stop working, which improves the equipment operation rate and reduces the failure shutdown caused by filter blockage.

[0021] like Figure 2 As shown, the first or second filter 2 comprises a square housing with a removable sealing cover 23 at the top. The inner wall of the housing is provided with multiple parallel insertion slots 21, flanked by T-shaped slots. Replaceable filter plates 22 are inserted into these slots, and the edges of the filter plates 22 are provided with T-shaped retaining edges that seal with the T-slots. The sealing cover is opened regularly to replace the filter plates. After cleaning a filter plate with heavy sediment, it can be replaced with a freshly cleaned filter screen without having to replace the filter housing. This reduces the cost of disassembly and installation.
