Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Referring to Figures 1-4 , a natural gas pipeline filter separator, comprising a device box 2. Docking pipelines 1 are fixedly communicated with both the front and rear sides of the device box 2. A flow dividing plate 6 and a flow collecting plate 10 are respectively fixedly connected to the inner wall of the device box 2. Corresponding flow dividing cavities are respectively arranged through the flow dividing plate 6 and the flow collecting plate 10. The function of the flow dividing cavity is to divide the natural gas transported from the docking pipeline 1 into strands. The flow dividing plate 6 and the flow collecting plate 10 are respectively communicated with the two docking pipelines 1. A plurality of separation boxes 13 are arranged in the device box 2. Both ends of the plurality of separation boxes 13 are fixedly communicated with a plurality of through pipes 11. The plurality of through pipes 11 are respectively communicated with the flow dividing cavities in the flow dividing plate 6 and the flow collecting plate 10 at corresponding positions. The divided natural gas will be transported into each separation box 13 through each through pipe 11 and can finally be concentrated into the docking pipeline 1 on the other side through the flow dividing cavity on the flow collecting plate 10. Control valves 7 are arranged on the side walls of the plurality of through pipes 11. Filtering devices are arranged in the plurality of separation boxes 13. The filtering device includes an inner groove arranged through the separation box 13, and a plurality of filter screens 14 are arranged in the inner groove. A cover 8 is arranged at the upper end of the separation box 13. The cover 8 is connected to the upper end of the separation box 13 through a plurality of locking screws 9.

[0021] Among them, a top cover 3 is arranged above the device box 2. A fixing device is arranged through the side wall of the top cover 3. The fixing device includes two through grooves arranged through the side wall of the top cover 3. Fixing screws 4 are respectively arranged through the two through grooves. Threaded grooves are respectively arranged through the upper ends of the flow dividing plate 6 and the flow collecting plate 10 in the device box 2 at corresponding positions.

[0024] In the present utility model, the docking pipes 1 on both sides are docked into the existing natural gas pipelines. After natural gas is introduced, the gas is transported to the flow dividing plate 6 in the device box 2. Through the flow dividing function of the flow dividing cavity, the gas is divided into multiple strands and respectively enters each separation box 13 through the through pipes 11. The multiple filter meshes 14 in each separation box 13 can all play a filtering role. The filtered gas will finally be concentrated together through the through pipes 11 on both sides and the flow dividing cavity on the flow collecting plate 10, and be transported away through the docking pipe 1 on this side.
