Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid-solid separation, in particular to a separator for oil and natural gas extraction and transportation. Background Art

[0002] In the process of oil and gas extraction and transportation, it is necessary to separate the droplets and solid particles or suspended matter in the gas to purify the product. Traditionally, gravity separators and filter separators are installed and operated as independent units. Gravity separators use the principle that particles settle under the action of gravity, while filter separators use the filter media in the filter area to prevent particles from passing through, while agglomerating small particle droplets into large particles; the mist collector is used in the mist collector area to remove droplets in the airflow.

[0003] However, there are some disadvantages to installing these two types of separators separately. First, they take up a large space and require many stages, instruments, and valves, which increases the size and complexity of the equipment, especially when multiple separation operations need to be performed simultaneously. Second, the independently installed separators require separate pipes and connectors, which increases the cost and maintenance difficulty of the system. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a filtration gravity integrated device, which has a simple structure, occupies a small area, and can effectively reduce the construction, use and maintenance costs of the equipment.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: a filtration gravity integrated device, comprising:

[0006] A gravity separator, the gravity separator comprising a separation chamber and a liquid storage chamber, the separation chamber and the liquid storage chamber are separated by a chamber partition, and the liquid storage chamber is connected to a liquid storage inlet pipe and a liquid storage discharge pipe;

[0008] Furthermore, the gravity separator is supported by two saddles, and a detachable cover is connected to the chamber partition.

[0009] Furthermore, a plurality of filter element assemblies are fixed in the filter cavity of the filter separator, and the filter element assemblies include filter cartridges, and the filter cartridges are placed horizontally.

[0010] Furthermore, a first demister is fixed below the gravity separator outlet of the gravity separator, and a second demister is fixed in the filter chamber of the filter separator.

[0011] Furthermore, a quick-opening blind plate is provided on the right side of the filter separator.

[0014] Furthermore, the liquid storage chamber is connected to a liquid level meter.

[0015] Furthermore, the filter separator is provided with a baffle at the inlet.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The integrated equipment directly integrates the gravity separator and the filter separator into one, so the structure is simple, the footprint is small, and the cost of equipment construction, use and maintenance can be effectively reduced;

[0018] 2. The filter separator is directly connected to the liquid storage chamber of the gravity separator. The sewage separated by the filter separator can be stored in the liquid storage chamber, which is convenient for observing the liquid level, effectively controlling the drainage time and drainage frequency, and ensuring that the gas overflowing from the liquid can also enter the filter separator for collection;

[0019] 3. Through the setting of the gravity separator and the two demisters in the filter separator, the droplets in the gas can be captured more thoroughly and settle downwards. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-3 As shown, the embodiment of the utility model provides a filtration gravity integrated device, comprising:

[0026] A gravity separator 1, the gravity separator 1 comprises a separation chamber 2 and a liquid storage chamber 3, the separation chamber 2 and the liquid storage chamber 3 are separated by a chamber partition, and the liquid storage chamber 3 is connected to a liquid storage inlet pipe 4 and a liquid storage discharge pipe 5;

[0027] A filter separator 6, the filter separator 6 is fixedly connected above the gravity separator 1, and a gravity separator 1 outlet is provided above the gravity separator 1. An upper connecting support 7 is also fixed on the gravity separator 1. The filter separator 6 is fixedly connected to the upper connecting support 7 through a lower connecting support 8. The filter separator 6 includes a filter chamber 9 and a defog chamber 10. The gravity separator 1 outlet and the filter chamber 9 of the gravity separator 1 are connected through a flanged connecting pipe, and the sewage outlet 20 of the filter separator 6 is connected to the liquid storage chamber 3 of the gravity separator 1.

[0028] The process of the utility model when in use is as follows: the gas to be filtered enters the air inlet 21 of the gravity separator 1, and is settled through the separation chamber 2 of the gravity separator 1 (a conventional gravity separation component is provided in the separation chamber 2, which belongs to the prior art, such as a plurality of baffles, which will not be repeated here), and the large droplets and solid particle impurities therein are settled at the bottom of the separation chamber 2, and then the remaining gas enters the filter separator 6 through the outlet of the gravity separator 1, and the remaining droplets and impurities in the gas are further filtered through the filter chamber 9 and the demisting chamber 10 therein, and finally the clean gas is discharged from the exhaust port of the filter separator 6, and the liquid deposited in the demisting chamber 10 is discharged from the sewage outlet 20 into the liquid storage chamber 3 of the gravity separator 1 for liquid storage. When the liquid is stored to a certain liquid level, the liquid is discharged through the liquid storage chamber 3. The reason for liquid storage is that there will be slow overflow of gas in the liquid. If it is discharged directly from the sewage outlet 20, it will cause gas loss. After working for a long time, the amount of gas lost is also a considerable waste.

[0029] Furthermore, the gravity separator 1 is supported by two saddles 11, and a detachable cover plate 12 is connected to the chamber partition. Specifically, the gravity separator 1 of the utility model is supported by two saddles 11, and the detachable cover plate 12 on the chamber partition of the gravity separator 1 can facilitate the entry of maintenance personnel to maintain and repair the gravity separator 1.

[0030] Furthermore, a plurality of filter core assemblies are fixed in the filter chamber 9 of the filter separator 6, and the filter core assemblies include a filter cartridge 13, and the filter cartridge 13 is placed horizontally. The filter core assembly fixed in the filter chamber 9 of the filter separator 6 of the utility model is used to isolate the liquid droplets and solid particle impurities by gas, ensuring that only fine liquid droplets are left in the gas entering the demisting chamber 10.

[0031] Furthermore, a first demister 14 is fixed below the outlet of the gravity separator 1, and a second demister 15 is fixed in the filter chamber 9 of the filter separator 6. Specifically, both the gravity separator 1 and the filter separator 6 are provided with demisters, so as to more thoroughly remove droplets in the gas.

[0032] Further, a quick-open blind plate 16 is provided on the right side of the filter separator 6. The quick-open blind plate 16 is provided to facilitate the entry of maintenance personnel and the replacement of the filter element.

[0033] Furthermore, an adjustment pad 17 is fixed between the upper connection support 7 and the lower connection support 8. The function of the adjustment pad 17 is to ensure that the connection between the gravity separator 1 and the filter separator 6 is tight, and fine-tuning and adjustment can be performed as needed.

[0034] Furthermore, the two sides of the filter separator 6 are located between the two sides of the gravity separator 1. The length of the filter is less than the length of the gravity separator 1, and the two sides of the filter separator 6 are located within the two sides of the gravity separator 1, making the entire device structure more compact.

[0035] Furthermore, a liquid level meter 18 is connected to the liquid storage chamber 3. By providing the liquid level meter 18, the operator can observe the liquid level of the liquid storage chamber 3 at any time, so as to discharge the deposited sewage and impurities in time.

[0036] Furthermore, the filter separator 6 is provided with a baffle 19 at the inlet. Specifically, the utility model provides a baffle 19 at the inlet of the filter separator 6, and the setting of the baffle 19 reduces the flow rate of the gas entering the filter separator 6, which is convenient for the next step of filtering.

[0037] The filter chamber of the filter separator 6 of the utility model shares the liquid storage, sewage discharge and liquid level with the separation chamber of the gravity separator 1, so it occupies a small area, has a higher degree of integration and lowers the installation cost.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
