Embodiment Construction

[0010] exist figure 1 Among them, the operation boat (1) is connected to the collection device (3) through a waterproof cloth pipe (9), and the collection device (3) is hung with a counterweight (7) so as to sink into the sea and contact the waterproof cloth fence (4) on the seabed. In case of methane leakage. The larger the collection device (3), the less methane leaks. In addition, an underwater camera can be added to the collecting device to realize visual operation. When using the present invention, the inner and outer water surfaces of the gas delivery pipe (9) are equal, and the liquid CO is transported through the small pipeline (10) in the gas delivery pipe (9). 2 Below 1500 meters underwater, after the combustible ice decomposes, methane is collected through the pipeline (9). After the collection is over, send an appropriate amount of Ca(OH) through a small pipe (10) 2 or CaO powder to neutralize the generated H 2 CO 3 , its chemical equation is:

Abstract

The invention discloses a method for collecting methanol from combustible ice, which is capable of preventing methanol leakage. The structure of a collection device is showed by the figure 1, and includes a work boat (1), a pipe (2), a collection device (3), a fence (4), the seafloor (5), the combustible ice to be exploited (6) and a counter weight (7). When in use, the collection device (3) is tightly attached to the seafloor; CO2 is injected into the collection device through the pipe; Ca(OH)2 or CaO powder is injected after the exploitation to neutralize the generated H2CO3.

Description

Technical field: [0001] The invention relates to a methane mining method in combustible ice, in particular to a collection method capable of preventing methane leakage. Background technique: [0002] At present, the known method of mining combustible ice is to directly inject liquid carbon dioxide into seawater to decompose combustible ice into methane and water, and collect it on the sea surface. However, methane is likely to leave the sea surface outside the sea surface collection area, causing methane leakage and triggering the greenhouse effect. Invention content: [0003] In order to overcome the fact that the existing methane mining devices in combustible ice are prone to methane leakage during mining, the invention provides a methane mining method in combustible ice. The mining method can not only mine methane in combustible ice, but also prevent methane leakage. [0004] The technical scheme adopted by the present invention to solve its technical problems is: put ...
