Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of phenolic resin processing, in particular to a scrubbing tower used for preparing phenolic resin. Background Art
[0002] Phenolic resin is an important synthetic resin material widely used in plastics, coatings, adhesives and other fields. During the production process of phenolic resin, the generated gas needs to be scrubbed to remove harmful impurities and reduce the reaction temperature.
[0003] In the patent with announcement number CN 204816152 U, a scrubbing tower is disclosed, comprising a tower body, an air inlet area formed in the tower body, a gas spray scrubbing area located above the air inlet area, and a spray water buffer area located below the air inlet area, wherein the gas spray scrubbing area is layered with a multi-layer filter plate device, each layer of the plate body is provided with a leakage area, and the leakage areas of the multi-layer filter plate device are projected in different areas in the vertical direction of the tower, so that the air flow or water flow presents a curved flow path. The scrubbing tower described in the utility model adopts a multi-stage filter plate device, which divides the scrubbing tower into multi-stage gas cyclone chambers. Since the leakage areas of the multi-layer filter plate device are projected in different areas in the vertical direction of the tower, the exhaust gas forms a cyclone in the divided cyclone chambers and effectively contacts the sprayed alkaline water to the greatest extent, thereby being absorbed by the alkaline water, achieving an effective scrubbing effect.
[0004] When the above-mentioned scrubber was working, it failed to process the exhaust gas in advance, causing dust and other particles to enter the scrubber along with the exhaust gas. The scrubber combined with the liquid to form mud, and the above-mentioned device did not process the mud and discharged it from the scrubber at any time, resulting in waste of spray liquid, which is not environmentally friendly. Moreover, the above-mentioned scrubber is equipped with a three-layer filter plate device, and the exhaust gas flow path is not subject to much restriction. The spray is sprayed out from the top once, and the spray liquid fails to fully combine with the exhaust gas, which is not conducive to cooling and purifying the exhaust gas.
[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
