Title:
SYNTHETIC GAS WATERLESS CIRCULATION WASHING AND PURIFYING DEVICE AND PURIFYING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/051034
Kind Code:
A1
Abstract:
A synthetic gas waterless circulation washing and purifying device and a purifying method. The device mainly comprises a first circulation purifying unit, a second circulation purifying unit, and a mop fan (9) connected to the first circulation purifying unit and the second circulation purifying unit. The first circulation purifying unit comprises a first shell (1) and a heavy tar circulation spraying system, and heavy tar and dust particles in gas are preliminarily captured by means of Venturi washing, liquid film impact and air cooling. Blades of the mop fan (9) are composed of a large number of fine wetting fiber filaments, and the large surface area of the blades is beneficial to further interception of heavy tar and dust particles. The second circulation purifying unit comprises a second shell (15) and an oil-based detergent regeneration system, and residual light tar in the gas is absorbed in a bubbling mode and by means of an activated carbon bed layer. According to the device and the method, gas purification is carried out by cyclic utilization of self-produced tar and carbon, waterless washing is carried out in the whole process, the device and the method are economical and environment-friendly, and the application prospect is wide.
