Multi-aperture plate type gas-liquid rectifying device

Abstract

The invention discloses a multi-aperture plate type gas-liquid rectifying device. The device comprises a rectifying plate assembled by pieces, wherein the rectifying plate comprises perforated plateswhich are spliced to one another, and the perforated plates are connected to one another and detachably fixed on a supporting beam; the perforated plates at different positions are provided with air holes of different aperture ratios, and the ventilation rates of different areas are adjusted by arranging the perforated plates of different aperture ratios in the corresponding areas to change the air volumes in the corresponding areas. The multi-aperture plate type gas-liquid rectifying device has the advantages that a smoke flow field in a tower is optimized by rectifying the smoke in differentareas of the tower, so that the smoke is more uniform in distribution after leaving a rectifying layer, a gas-liquid reaction is more efficient, and the subsequent desulfurization efficiency and defogging effect are improved; the device is segmented, thereby being convenient to access and replace.

Description

technical field [0001] The invention relates to the technical field of wet flue gas desulfurization, in particular to a multi-aperture plate type gas-liquid rectification device for uniform airflow distribution and enhanced gas-liquid rectification efficiency. Background technique [0002] With the improvement of national environmental protection requirements and the demand of enterprises for "energy saving and consumption reduction", controlling the emission value of sulfur content in the net flue gas is the most important production index of the desulfurization system. At the same time, the power consumption generated by the spray layer is also an important economic index. Improving the desulfurization efficiency and reducing the power consumption of the spray tower are directly related to the environmental protection requirements and economic efficiency of the factory. [0003] At present, the wet flue gas desulfurization system is widely used in the domestic desulfuriza...

Problems solved by technology

However, there are still some problems in the process of use, such as: after the flue gas enters the tower, the air flow is unevenly distributed, the gas-liquid contact reaction efficiency is low, the orifice plate is easy to block, and it is difficult to repair and replace; it also causes subsequent drift areas. A series of problems such as the escape of flue gas and the easy blockage of the demister
