The invention relates to a spray tower sewage treatment device and method for purifying tail gas generated in the production of artificial boards, and belongs to the technical field of artificial board sewage treatment. According to the technical scheme, a roller (1) is supported by four rollers, a filter screen (2) is mounted on the roller (1); a circular water inlet is formed in the left side ofthe roller and is connected with a water inlet pipe (20); a discharging hopper (8) matched with a discharging port of the roller is arranged on the lower right portion of the roller, a discharging port is formed in the bottom of the discharging hopper (8), a spiral pipe (9) is transversely arranged and located below the discharging port, the upper end of the spiral pipe (9) is communicated with the discharging port in the bottom of the discharging hopper (8), a spiral (5) is arranged in the spiral pipe (9), and a water filtering mechanism is arranged at the outlet of the spiral pipe (9). Thedevice and method have the advantages that wood fibers in spraying sewage are separated out, the processed sewage can be used in cycle, water resources are saved, the environment is protected, and fibers and dust in spraying tower sewage can be recycled.
Description
technical field [0001] The invention relates to a spray tower sewage treatment device and method for purifying the tail gas produced by artificial boards, and belongs to the technical field of artificial board sewage treatment. Background technique [0002] In the production process of medium fiber density board, the fiber air delivery process will produce cyclone exhaust gas, and the main pollutant contained in the exhaust gas is wood fiber dust. Now the environmental protection situation is getting more and more severe, and the requirements for the emission of exhaust gas during the production of medium fiber density boards are also getting higher and higher. At present, the dust removal method adopted by the existing technology for this kind of tail gas is a combination of cyclone separator dust removal and spray dust removal, that is, the tail gas is dusted by the cyclone separator and then discharged after the dust removal reaches the standard by the spray tower. There...
