Embodiment Construction

[0019] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0020] like Figure 1 ~ Figure 3 As shown, a natural gas hydrate slurry pipeline solid blockage treatment device has a thermal decomposition chamber installed under the natural gas pipeline 18, and the thermal decomposition chamber includes a first decomposition chamber 16 for thermally decomposing pulverized blockages into natural gas , the second decomposition bin 1 for receiving the natural gas decomposed by the first decomposition bin 16 , and the heating bin 24 for heating the first decomposition bin 16 .

[0021] The first decomposing bin 16 is connected with the plug feed pipeline 21 communicated or closed with the natural gas pipeline 18, and the uppe...

Abstract

The invention relates to a treatment device for solid blockages in natural gas hydrate slurry pipelines, comprising a first decomposition chamber for heating and decomposing the blockages into natural gas, a second decomposition chamber for receiving the natural gas decomposed by the first decomposition chamber, and a device for heating the first decomposition chamber The heating chamber, the first sensor and the second sensor that sense the position of the pig moving in the natural gas pipeline, the first decomposing chamber is connected with a blockage feed pipe that communicates with or closes the natural gas pipeline, and is also equipped with a radial Move the pipeline blocking plate that closes or opens the natural gas pipeline, and the upper end of the second decomposition bin is connected with a natural gas discharge pipeline that is connected or closed with the natural gas pipeline; a cutting device for breaking blockages is installed on the wall of the natural gas pipeline. The invention breaks the blockage in the natural gas pipeline, decomposes it into natural gas by heating and discharges it into the natural gas pipeline, thereby realizing the function of converting the blockage into natural gas underground during the transportation of natural gas.

Description

technical field [0001] The invention relates to the technical field of natural gas transmission, in particular to a treatment device for solid blockages in natural gas hydrate slurry pipelines. Background technique [0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. Natural gas pipelines are needed to transport natural gas from underground to cities. Natural gas pipelines refer to pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas transmission. pipeline. The use of natural gas pipelines to transport natural gas is the main way to transport large quantities of natural gas on land. [0003] Natural gas contains saturated water vapor under formation conditions, and its water vapor content depends on ...
