The invention discloses a decomposition device for simulating the evolution law of natural gas hydrate, which comprises a separation cylinder, and the end part of the separation cylinder is hermetically connected with a dissociation mechanism for decomposing the natural gas hydrate to obtain gas and liquid. According to the invention, liquid diversion and filter hole regulation and control operation can be realized through circulating the filter guide mechanism, the condition that the filter holes are blocked is avoided, during implementation, the gas and the liquid are divided into a plurality of units through the unit isolation mechanism, and then the unit isolation mechanism is used for separating the gas and the liquid into the plurality of units, so that the gas and the liquid are separated into the plurality of units; then, the circulating filtering and guiding mechanism can filter liquid in each unit in a targeted manner and guide the liquid to fall to the bottom of the separation barrel so as to carry out preliminary anti-blocking operation on the filtering holes, and then, gas after the liquid is filtered can be guided to flow back so as to regulate and control the diameter of the liquid filtered by the circulating filtering and guiding mechanism; and the anti-blocking effect of the filter holes is better.
Description
technical field [0001] The invention relates to the technical field of flammable ice evolution simulation, in particular to a decomposition device for simulating the evolution law of natural gas hydrate. Background technique [0002] Natural gas hydrate is flammable ice, which is an ice-like crystalline substance formed by natural gas and water under high pressure and low temperature conditions. Because of its appearance like ice, it burns when it meets fire, so it is called "combustible ice", "solid gas" and "gas hydrate" "vapor ice", the chemical formula is CH 4 ·nH 2 O. Natural gas hydrates are commonly found in deep-sea sediments or onshore permafrost, and are ice-like crystalline substances formed by natural gas and water under high pressure and low temperature conditions. [0003] In order to know the evolution law of natural gas hydrate, it is necessary to simulate the reverse phase deformation of hydrate, and one of the more important mechanisms in the simulation ...
