Technical Field
The invention belongs to the field of environment-friendly equipment, and particularly relates to a high-efficiency gas-liquid separator of a desulfurization system.
Background
In chemical production, exhaust gas generated by boilers, reaction kettles and the like usually contains more sulfides, and in order to prevent pollution to the atmosphere, the exhaust gas must be treated by a desulfurization and dust removal system.
Most of traditional gas-liquid separators adopt a gravity settling or centrifugal force separation mode to realize gas-liquid separation, however, the gravity settling mode only depends on liquid gravity to perform separation, the efficiency is low, the separation effect is poor, and the requirement on environmental protection cannot be met; and the centrifugal force separation mode needs to drive gas and liquid to rotate rapidly through the separation fan, and although a good separation effect can be achieved, the energy consumption is high, and the equipment cost is also high.
