Abstract

The invention discloses a natural gas hydrate reaction device which is characterized by comprising a gas supplying system, a water supplying system, a cooling system, a spray reaction system, a measuring system and an adjusting system, wherein the gas supplying system is connected with the spray reaction system, the water supplying system is connected with the spray reaction system, the two sidesof the cooling system are respectively connected with the spray reaction system, and the measuring system is arranged on the spray reaction system; the spray reaction system comprises an atomizing nozzle, a reaction pipe and a reaction kettle; the atomizing nozzle at the inlet end of the reaction pipe can make natural gas and water be scattered in a fog shape, so that a gas-liquid mixing efficiency is fully improved; furthermore, the reaction pipe is in a spiral coil shape, so that a flow rate and disturbance of gas-liquid two-phase flow are improved, a gas-liquid mass transfer efficiency is further improved; in addition, a heat exchange area is increased, reaction heat can be quickly radiated, a heat transfer efficiency is also improved, and the advantages of increasing hydrate reaction driving force and shortening induction time are achieved.

Description

technical field [0001] The invention relates to the field of natural gas, in particular to a natural gas hydrate reaction device. Background technique [0002] Natural gas hydrate is an ice-like solid substance composed of natural gas and water molecules, also known as methane hydrate. According to theoretical calculations, 1m3 of saturated natural gas hydrate can release 164m3 of methane gas under standard conditions, and its energy density (the amount of methane per unit volume of sediment under standard conditions) is 10 times that of other non-traditional energy sources. 2 to 5 times the energy density, so natural gas hydrate storage technology is a method of high-density energy storage. The formation process of natural gas hydrate is very complicated, with exothermic effect, involving heat and mass transfer between gas, liquid and solid phases, which requires a certain induction time, and the whole process of hydrate formation is also affected by temperature, pressure,...
