Abstract

The method discloses a gas-hydrate-separation bubbling reinforcing device, a gas-hydrate-separation purifying reinforcing device based on the same and a gas purifying reinforcing method, and relates to the field of coal. The problems that the gas-hydrate-separation rate is low, and the separation concentration and the methane recovery rate are low are solved. By means of the gas-hydrate-separation bubbling reinforcing device, the contact area between gas and an accelerant solution is greatly increased, the content of the gas entering a liquid phase is increased, the separation rate is accelerated, and the gas-hydrate separation concentration and the methane recovery rate are increased. According to the gas-hydrate-separation purifying reinforcing device and the purifying reinforcing method, the temperature is adjusted through a temperature control box, the pressure and the temperature of the gas in a hydrate reaction kettle are monitored through pressure sensors and temperature sensors in real time, and are stored and observed through an industrial personal computer and a data acquisition device in real time, the temperature of the temperature control box and the operating sequence of the device can be conveniently adjusted in time, and the gas-hydrate-separation purifying reinforcing device and the purifying reinforcing method are suitable for purifying other kinds of gas.

Description

technical field [0001] The present invention relates to the field of coal. Background technique [0002] Coal mine gas, also known as coal seam gas, is a multi-component mixed hydrocarbon dry gas mainly composed of alkanes. 4 The vast majority, with a small amount of C 2 H 6 , C 3 H 8 and C 4 H 10 , this CH 4 Dry gas is 75% carbon, 25% hydrogen, and some non-hydrocarbon gases like NH 3 , CO 2 , CO and H 2 S, etc., are associated gases that mainly exist in coal mines, and are also one of the main causes of underground accidents in coal mines. Among them, the main component of gas is CH 4 Is an ideal gas fuel, it is colorless and odorless, pure CH per cubic meter 4 The calorific value is 34000KJ, that is to say 1m 3 CH 4 After complete combustion, it can generate heat equivalent to 1kg of anthracite coal. Compared with coal combustion, gas combustion products are mainly carbon dioxide and water, and the pollution generated by its combustion is generally only 1 / 40...
