The invention discloses a formaldehyde recovery tower. The formaldehyde recovery tower comprises a tank main body with an open top end, and comprises an upper end socket, a lower end socket, and a plurality of packing cylinders and a bottom cylinder which are sequentially arranged between the upper end socket and the lower end socket from top to bottom, and a supporting grid is arranged at the bottom of each packing cylinder; a liquid inlet assembly is arranged at the end part of each packing cylinder, each liquid inlet assembly comprises a material pressing grid plate, a groove disc distributor and a distribution pipe, each groove disc distributor is arranged above the corresponding material pressing grid plate, the distribution pipe extends into the packing cylinders from the outside ofthe packing cylinders and is arranged corresponding to the groove disc distributor, and a structured packing is arranged in the packing cylinders. According to the formaldehyde recovery tower, a regular packing is arranged in the formaldehyde recovery tower to replace bulk packings in the prior art, the regular packing is high in density and large in area, it is guaranteed that formaldehyde physicochemical liquid is more uniformly and comprehensively filtered, and the filtering effect is better; and meanwhile, the plurality of packing cylinders are arranged from top to bottom, and the packingcylinders at different positions can be distributed and added according to the concentration of formaldehyde, so that the tower is suitable for formaldehyde physicochemical solutions with different concentrations and is more efficient and wide in range.
Description
technical field [0001] The application relates to the field of recovery towers, in particular to a formaldehyde recovery tower. Background technique [0002] In the prior art, bulk packing is often used for filtering in the formaldehyde recovery tower, and the filtering effect is relatively general and cannot meet the requirements. Contents of the invention [0003] The purpose of the present invention is to provide a formaldehyde recovery tower to overcome the deficiencies in the prior art. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] The embodiment of the present application discloses a formaldehyde recovery tower, which is characterized in that it includes an upper head, a lower head, and a plurality of packing cylinders and bottom cylinders arranged between the upper head and the lower head in sequence from top to bottom. The upper head is provided with an air outlet, the lower head is provided with ...
