Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to natural gas double-tube drying equipment. Background Art

[0002] When installing a gas pipeline, it is necessary to ensure that the ground is clean, flat, and the soil is properly prepared. In addition, the necessary equipment and materials must be assembled, and the trenches must be accurately excavated according to the design drawings. The prefabricated pipes are placed in the trenches section by section and connected by welding or threading. After the installation is completed, a pressure test is performed to ensure the pipeline is sealed and safe. In terms of maintenance, regular pipeline inspections are basic measures. The inspection work includes external and internal inspections to detect potential problems early and ensure the normal operation of the pipeline. At the same time, anti-corrosion treatment is also key. Measures such as coating anti-corrosion, heat treatment anti-corrosion and anode protection can effectively prevent pipeline corrosion.

[0003] When connecting a natural gas pipeline, the natural gas inside needs to be dried. If there is undried moisture inside the natural gas, when the natural gas is cooled, stored and transported, the internal moisture will freeze and cause damage to the inside of the pipe due to the low temperature. Therefore, it is particularly important to dry the natural gas before transporting it. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model provides a natural gas double-tube drying device, such as Figure 1-5 As shown, it includes a working chassis 101, and two dryers 103 are arranged above the working chassis 101. The dryers 103 on both sides are symmetrically arranged. Vertically arranged low support rods 102 are fixed between the bottoms of the dryers 103 on both sides and the upper end surface of the working chassis 101. The low support rods 102 play a role of fixed connection and support. A drying chamber 116 is arranged in the dryer 103, and a plurality of drying plates 117 are arranged in the drying chamber 116. The drying plates 117 are arranged in a matrix from top to bottom, and a plurality of molecular holes 115 are arranged in the drying plates 117.

[0025] It should be noted that the mesh number of the molecular pore 115 can be changed according to the actual application scenario, and can separate the moisture in the gas flowing through it to achieve a drying effect.

[0026] Furthermore, a mounting groove 114 is connected to one side wall of the drying chamber 116, a mounting guide plate 113 is fixedly provided on one side of the outer end surface of the drying plate 117, a plurality of mounting guide plates 113 that can move up and down are provided inside the mounting guide plate 113, and the mounting guide plate 113 is fixedly connected to one side of the outer end surface of the drying plate 117.

[0027] Furthermore, an airflow guide plate 108 is fixedly provided at the top of the dryer 103 , and a flow velocity detector 104 is fixedly provided at one side of the top of the airflow guide plate 108 .

[0028] It should be further explained that the flow rate detector 104 is capable of detecting the air flow rate flowing through the air flow guide plate 108 .

[0029] Furthermore, an input pipe opening 105 opening upward is provided at the top of the airflow guide plate 108, and the input pipe opening 105 is connected to the natural gas pipeline.

[0030] Furthermore, an output pipe 118 is provided at the bottom of the dryer 103 , and a regulating pipe 111 is provided between the output pipes 118 on both sides.

[0031] Furthermore, an input pipe 107 is connected to one side of the outer end surface of the airflow guide plate 108, a switching pipe 106 is connected between one end of the input pipe 107 and the middle position of the outer end surface of the regulating pipe 111, and a regulating valve 112 is provided at the connection between the switching pipe 106 and the output pipe 118.

[0032] It is worth noting that the regulating valve 112 is used to control the connection state between the switching pipeline 106 and the regulating pipeline 111 .

[0033] Furthermore, a moisture detector 109 is fixedly provided on one side of the top of the working chassis 101 , and the regulating pipe 111 passes through the moisture detector 109 .

[0034] It should be further explained that the moisture detector 109 is provided with a detector and is capable of detecting the moisture content inside the gas passing through the regulating pipe 111 .

[0035] When using this solution, first, the working chassis 101 is moved as a whole to the natural gas drying position, and the natural gas input pipeline that needs to be input and dried is connected to the input pipe port 105. At this time, according to the natural gas drying requirements, the drying plate 117 containing molecular holes 115 of different mesh sizes is installed in the drying chamber 116, and is installed to the appropriate position in the installation groove 114 through the side installation guide plate 113, and the working settings inside the drying plate 117 are completed.

[0036] When natural gas is dried, the natural gas is input into the air flow guide plate 108 and then into the drying chamber 116 through the input pipe port 105. During this process, the flow rate is monitored by the flow rate detector 104. After the input natural gas is dried and filtered by the multi-layer drying plate 117, the dried natural gas is output into the regulating pipe 111 through the output pipe 118 and output outward through the regulating pipe 111. At the same time, the air flow passing through is monitored for drying by the moisture detector 109. When it is detected that the moisture content inside the treated natural gas is high, the regulating pipe 111 is rotated to connect with the switching pipe 106 and the dryers 103 on both sides are connected in series. At this time, after the natural gas is dried inside the dryer 103 at the front end, it is input into the dryer 103 on the other side through the switching pipe 106. By extending the pipe path through which the natural gas flows, the drying time is extended and the drying effect of the natural gas is further improved.

[0037] When the moisture detector 109 detects that the internal moisture flowing through is less, the regulating valve 112 is switched at the same time, and the connection between the regulating pipeline 111 and the switching pipeline 106 is disconnected. At this time, the input pipe openings 105 on both sides are connected to the natural gas input pipeline at the same time. At this time, the dryers 103 on both sides dry the natural gas at the same time, thereby improving the drying output efficiency of the natural gas.

[0038] When internal inspection and drainage are required, the top of the dryer 103 is opened, and the drying plates 117 of each layer are guided outward and removed through the installation groove 114, so as to facilitate subsequent inspection and drainage work, thereby extending the service life of the entire device.
