Device for disposing solid blockages in natural gas hydrate slurry pipeline

Abstract

The invention relates to a device for disposing solid blockages in a natural gas hydrate slurry pipeline. The device comprises a first decomposition bin for heating and decomposing the blockages intonatural gas, second decomposition bins for receiving the natural gas decomposed by the first decomposition bin, a heating bin for heating the first decomposition bin, a first sensor and a second sensor, wherein the first sensor and the second sensor are used for sensing the position of a pipe cleaner moving in a natural gas pipeline; the first decomposition bin is connected with a blockage feedingpipeline which communicates with or does not communicate with a natural gas pipeline, and pipeline blocking plates capable of moving in the radial direction to close or open the natural gas pipelineare further arranged; the upper ends of the second decomposition bins are connected with a natural gas discharging pipeline which communicates with or does not communicate with the natural gas pipeline; and a cutting device for crushing the blockages is mounted on the wall of the natural gas pipeline. According to the device, after being crushed, the blockages in the natural gas pipeline are decomposed into the natural gas in a heating manner and then is discharged into the natural gas pipeline again, so that the function of converting the blockages into the natural gas underground in the natural gas transportation process can be realized.

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 ...
