Problems solved by technology
Natural gas hydrates are mainly distributed in polar regions and deep-water continental slopes, and about 95% are stored in deep-water areas. At present, the target areas for trial mining in permafrost and sea areas are diagenetic gas hydrate orebodies with underlying free gas. , heat injection, injection and CO 2 Although the total amount of fine-grained fractured and dispersed natural gas hydrate stored in deep water and shallow layers is large, the mining method is still blank due to its shallow burial depth, non-diagenesis, and poor cementation

The invention provides a reaction kettle sealing device which comprises a connection head which is fixedly connected with the wall of a reaction kettle, a compression nut which is in screwed connection with the connection head and is screwed into the connection head, and a thermocouple drivepipe which can penetrate through the compression nut, a cone-shaped sealing pad and the connection head in sequence, wherein the compression nut and the connection head are sealed by the cone-shaped sealing pad. The reaction kettle sealing device has the beneficial effects that 0.02mm deformation caused by compressing the cone-shaped sealing pad can seal 40-50Mpa pressure, so that a sealing performance is good, a high sealing requirement of a natural gas hydrate synthetic reaction kettle can be met, the stability of the intensity of pressure in the natural gas hydrate synthetic reaction kettle is ensured, and a technical support is provided for fast synthesizing a large quantity of aquo-complexes in a laboratory.
Description
technical field [0001] The invention relates to the technical field of a natural gas hydrate synthesis reaction kettle, in particular to a reaction kettle sealing device and a reaction kettle. Background technique [0002] Gas hydrate is a non-stoichiometric clathrate compound, 1m 3 Hydrate can be stored for 150~180m 3 of natural gas. Natural gas hydrate is a special form of natural gas, which has the characteristics of wide distribution, large accumulation scale and high energy storage density. Natural gas hydrates are mainly distributed in the polar regions and deep-water continental slopes, and about 95% are stored in deep-water areas. At present, the target areas for trial mining in permafrost and sea areas are diagenetic gas hydrate orebodies with underlying free gas. Decompression can be used to , heat injection, injection and CO 2 Although the fine-grained fractured and dispersed natural gas hydrates stored in deep water and shallow layers are large in total, the ...
