Self-turning type denitration and desulfurization tower capable of efficiently adsorbing waste gas

Abstract

The invention discloses a self-turning type denitration and desulfurization tower capable of efficiently adsorbing waste gas, which belongs to the field of waste gas treatment, and is characterized inthat through the arrangement of interval fluctuating filter membranes, the convex radian of the fluctuating membranes is effectively changed by controlling the change of the introduction speed of thewaste gas, so that the waste gas can be efficiently adsorbed. The position of the solid adsorbent on the upper surface is changed to a certain extent, the effect of self-turning is achieved while theeffect of the reverse concave film is matched, the situation that the solid adsorbent is locally distributed unevenly under the protruding effect of the fluctuating film is effectively avoided, and the solid adsorbent can make more comprehensive and sufficient contact with waste gas, and better adsorbing effect can be achieved. Compared with the prior art, under the self-turning action of the solid adsorbent, the paving thickness of the solid adsorbent can be relatively large, so that the replacement frequency of the solid adsorbent is remarkably reduced, and the influence of the solid adsorbent on the adsorption efficiency of waste gas treatment is reduced.

Description

technical field [0001] The invention relates to the field of waste gas treatment, and more specifically relates to a self-turning denitrification and desulfurization tower for efficient adsorption of waste gas. Background technique [0002] Desulfurization and denitrification is one of the important technical measures to prevent and control air pollution. [0003] Desulfurization: generally refers to the process of removing sulfur from fuel before combustion and desulfurization before flue gas emission. It is one of the important technical measures to prevent and control air pollution. Desulfurization methods generally include pre-combustion, combustion and post-combustion desulfurization. Many flue gas desulfurization processes have been widely used in industry, and it also has important practical significance for the treatment of exhaust gas from various boilers and incinerators. [0004] Denitration: In order to prevent excessive NOx pollution of the environment after ...

Problems solved by technology

[0007] Aiming at the problems existing in the prior art, the object of the present invention is to provide a self-turning denitrification and desulfurization tower for efficient adsorption of waste gas, which can effectively change the flow rate of waste gas by setting up and down undulating filter membranes at intervals and by controlling the change of the feed rate of waste gas. The convex curvature of the undulating film makes the position of the solid adsorbent on the upper surface change to a certain extent, achieving the effect of self-turning. At the same time, it cooperates with the function of the reverse concave film to effectively avoid the solid adsorbent being caused by the convexity of the undulating film. Local uneven distribution occurs, so that the solid-state adsorbent can fully and fully contact with the exhaust gas, and achieve a better adsorption effect. Under the self-turning action of the solid-state adsorbent, compared with the existing technology, the solid-state adsorption The tile thickness of the agent can be thicker, thereby significantly reducing the frequency of replacing the solid adsorbent and reducing its impact on the adsorption efficiency of waste gas treatment
