Swiss roll type gas-water separator and gas-water separation method

Abstract

The invention provides a Swiss roll type gas-water separator and a gas-water separation method. The Swiss roll type gas-water separator comprises a spiral winding drum and a Swiss roll type channel separator which is formed by a square box body connected with an opening end of the spiral winding drum, wherein the top of the Swiss roll type channel separator is provided with a gas outlet pipe, the lower part of the square box body is provided with a gas inlet pipe and a water outlet pipe at an interval, and a water filter plate fixed in the square box body is arranged between the gas inlet pipe and the water outlet pipe. Water-containing gas is guided into the gas inlet pipe and flows into the Swiss roll type channel separator after passing through a porous barrier with the functions of explosion insulation and explosion suppression. The water-containing gas flows along a slope-shaped barrier in the spiral winding drum in a ring with the radius being gradually reduced, the centrifugal force of the water-containing gas is changed when the water-containing gas flows, the water-containing gas collides with the inner wall of the spiral winding drum under the flow guide function of the slope-shaped barrier, and gas and water can be separated from each other under the dual functions of gravity and centrifugal force. The Swiss roll type gas-water separator is simple in structure, convenient to operate, good in gas-water separation effect, high in separation efficiency and convenient to install, has the functions of explosion insulation and explosion suppression, and can improve the gas delivery safety.

Description

technical field [0001] The invention relates to a Swiss coil type gas-water separator and its method, which is especially suitable for the gas-water separation in the gas transportation process of coal mine gas, natural gas and the like. Background technique [0002] Coal mine gas is not only a gas with strong greenhouse effect, but also a clean energy. With the deepening of coal mine gas drainage work, the amount of gas drainage has increased year by year. In 2012, the amount of gas drainage in mines was 14.1 billion cubic meters, and the utilization amount was 5.8 billion cubic meters, a year-on-year increase of 23.2% and 20.2% respectively. It can be seen that more and more attention has been paid to the utilization of gas, which has also brought new attempts to environmental protection and new energy development. In the process of gas utilization, an urgent problem to be solved is the problem of gas transportation, especially the transportation of low-concentration gas....
