[0058] Example 11: This embodiment is a further optimization based on any of the above embodiments. The parts identical to the aforementioned technical solutions will not be repeated here. Figures 1-10 As shown, in order to better realize the non-pressure vessel type pipeline filter separation skid of the present invention, the following structure is specially adopted: the filter plate 7 of the non-pressure vessel type pipeline filter separation skid is an innovative pipeline filter plate developed according to production needs.

[0059] The main process of using this invention is as follows: When used as a non-pressure vessel type pipeline filtration and separation skid, a single-pipeline filtration and separation mode is formed: the incoming gas from the station enters the first three-way valve 5 for natural gas impurity filtration, and then enters the second three-way valve 13 for free water separation. After separation, the gas goes to the downstream station; impurities and separated water are stored through the impurity / storage pipe 24 for discharge. The process is equipped with pressure gauges, level gauges, vent ports (venting interfaces), and cleaning water injection nitrogen replacement ports (cleaning injection section).

[0060] When there are two sets of non-pressure vessel type pipeline filter separation skids: they can form a one-in-one standby mode; they can be used in parallel; and they can be used in series to increase the filtration and separation effect.

[0061] The working principle of this invention is as follows: When a non-pressure vessel type pipeline filtration and separation skid is used, a single-pipeline filtration and separation mode is formed: Before entering the first three-way valve 5, the incoming gas undergoes a diameter reduction to instantly decrease the flow rate of solid impurities and liquid water in the gas, and then flows downwards into the impurity / storage pipe 24 due to inertia. The gas then flows upwards through multiple filter plates 7 on the straight pipe section 8 at the rear end of the first three-way valve 5 to remove impurities from the natural gas a second time. After impurity removal, the natural gas passes through the separation structure 14 on the inlet and outlet gas mains of the second three-way valve 13 to separate free water from the natural gas. The separated gas then flows to the downstream station.

[0062] Multi-layer filtration structure (multiple filter plates 7 + stabilizing rings 20): This innovative design employs a full-coverage impurity removal filter layer, fixed to baffles in multiple layers to remove impurities. The filter layer (composed of multiple filter plates 7 + stabilizing rings 20) can be made of different materials depending on the natural gas operating conditions, such as pressure, flow rate, and sand content. For example, copper wire balls can be used for the full-coverage filter layer.

[0063] Separation Plate 35: An innovative design that uses single or multiple layers of finely porous materials of different materials, hardness, and density to separate free water, depending on the natural gas operating conditions, pressure, flow rate, and water content. The porous materials can be one or more of materials such as copper wire balls or loofah sponges, used in combination.

[0064] Multiple valves, various tees, and straight pipe sections 8 are connected by welding. The separator plate 35 is connected to the baffle bar in the baffle tee by hooking it.

[0065] When there are two sets of non-pressure vessel type pipeline filter separation skids: they can be used in a one-in-one standby mode; they can be used in parallel; and they can be used in series to increase the filtration and separation effect.

[0066] This invention allows for the addition of remote transmission devices (pressure transmitters, level transmitters) for metering, pressure, and liquid level measurement to meet different needs. The drain valve can be configured for manual, electric, or pneumatic operation as required. Data is integrated on the skid and then connected to the downstream station monitoring system. The entire skid is grounded.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
