Title:
A vapor-liquid contact method and a gas liquid contact device
Document Type and Number:
Japanese Patent JP5938346
Kind Code:
B2
Abstract:
[Problem] To increase the efficiency with which a gas and a liquid are brought into contact and thereby produce fine liquid droplets, reduce the amount of energy, space and maintenance required, and allow sub-micron-sized particles to be collected from the gas while absorbing the gas. Also, to provide a highly-efficient gas-liquid contact method and gas-liquid contact device which can easily be scaled up. [Solution] A gas-liquid contact method and gas-liquid contact device whereby a gas and a liquid are brought into contact and mixed. In in the gas-liquid contact device (1), a first gas-liquid contact section (3) having inset helicoid vanes is provided on the upstream side of a cylindrical container (2), a second gas-liquid contact section (4) having inset helicoid vanes is provided on the downstream side of the first gas-liquid contact section (3), and spray nozzles (22, 23) are provided above the first and second gas-liquid contact sections (3, 4). In the gas-liquid contact method, a gas which contains a dissimilar material and has an elevated or reduced pressure is introduced from the upstream part of the container (2), a liquid is supplied and sprayed from the spray nozzles (22, 23), and the gas and liquid are made to traverse the first gas-liquid contact section (3) and the second gas-liquid contact section (4) from top (the upstream side) to bottom (the downstream side) in a manner such that the gas has a speed of 20-150 m/s in the first gas-liquid contact section (3), and a speed of 0.5-20 m/s in the second gas-liquid contact section (4).
