A self-turning exhaust gas denitrification and desulfurization tower with high-efficiency adsorption

Abstract

The invention discloses a self-turning type denitration and desulfurization tower for high-efficiency adsorption of waste gas, belonging to the field of waste gas treatment. A self-turning type of denitration and desulfurization tower for high-efficiency adsorption of waste gas can control the inflow speed of waste gas through the setting of interval undulating filter membranes. change, and then effectively change the convex curvature of the undulating film, so that the position of the solid adsorbent on the upper surface changes to a certain extent, achieving the effect of self-turning and cooperating with the effect of the reverse concave film, effectively avoiding the solid adsorbent on the undulating film. The local uneven distribution caused by the bulge occurs, so that the solid adsorbent can contact the exhaust gas more comprehensively and fully, and play a better adsorption effect. The existing technology enables the solid adsorbent to have a thicker tile thickness, thereby significantly reducing the frequency of replacing the solid adsorbent and reducing its impact on the adsorption efficiency of exhaust gas treatment.

Description

technical field [0001] The invention relates to the field of waste gas treatment, and more particularly, to a self-turning type denitration 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 the desulfurization process before flue gas emission. It is one of the important technical measures to prevent and control air pollution. There are generally three types of desulfurization methods: pre-combustion, in-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] Denitrification: In order to prevent excessive NOx poll...

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
