Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of demisters, in particular to a demister used for wet desulfurization and dust removal. Background Art
[0002] At present, many industries in China are equipped with wet desulfurization and dust removal environmental protection equipment. Since the slurry spray and flue gas are operated in a countercurrent manner, more slurry and dust are mixed in the water mist and carried upward by the flue gas. In order to capture the water mist that is carried away and to ensure the normal operation of the rear-end electric dust collector, a demister is installed in the tower. During use, water vapor and slurry dust will adhere in the gap of the demister. The daily demister uses upper and lower flushing water for intermittent flushing to reduce the adhesive on the demister and avoid large-scale blockage. Due to too many flushing times with new water, the liquid level in the tower will rise too quickly and overflow, and it will not be able to operate normally. In order to solve the problem of excessive primary water consumption and the inability to discharge the overflowed slurry water, the overflowed slurry water is generally precipitated and mixed with primary water for reuse The demister is flushed, so condensed gypsum will gradually accumulate on the demister and cause blockage. Another reason is that the demister relies on the rising water vapor airflow to collide with the blades and condense to capture the water vapor in the flue gas. Therefore, there are dead angles in the demister blades that block each other, and the upper and lower flushing water cannot flush them in place. As time accumulates, they will stick together into blocks. The flue gas composition of many industries is relatively complex, and there are oils and colloids with strong adhesion, which are difficult to flush away. For example, the flue gas desulfurization purification facilities of the calcining and roasting kilns in aluminum anode production enterprises have such serious problems. After the demister is blocked, the environmental protection equipment will not be able to operate normally, the increased resistance will cause the energy consumption to increase, and the production system will be forced to shut down. For this reason, technical improvements are made to the demister in the prior art. Utility Model Content
