For reaching this object, the present invention by the following technical solutions:
A kind of efficiency of waste gas desulfurizer, it comprises spray column, spray system, slurry pool and automatic makeup sizing device, described spray column is provided with air inlet and exhaust outlet, described slurry pool is positioned at the below of described spray column, wherein, described spray system is arranged in described spray column, it comprises circulating pump, first screw spraying pipe, second screw spraying pipe and top spray pipe, described first screw spraying pipe is arranged at the inwall of described spray column, described second screw spraying pipe is arranged at the center of described spray column, and described first screw spraying pipe and the second screw spraying pipe are crisscross arranged, described top spray pipe is arranged at described first, in spray column above two screw spraying pipes, described first screw spraying pipe, second screw spraying pipe is connected in described circulating pump by pipeline with top spray pipe, and three showers all offer several mouth sprays.
Especially, the mouth spray on described first screw spraying pipe, the second screw spraying pipe and top spray pipe is all provided with atomizer.
Especially, described automatic makeup sizing device comprises slurry tank, adds stock pump, adds slurry pipeline and pH value probe, the described stock pump that adds is connected with described slurry tank by pipeline, described one end adding slurry pipeline connects and adds stock pump, the other end is arranged in described slurry pool, and described pH value probe and the described stock pump that adds communicate to connect.
Especially, described first screw spraying pipe is connected on the inwall of described spray column by spot welding or any one mode be arranged on fixed support.
Beneficial effect of the present invention is, compared with prior art described efficiency of waste gas desulfurizer is by arranging the first screw spraying pipe, the second screw spraying pipe and top spray pipe, and the rising in spiral shape of the second screw spraying pipe, and be crisscross arranged with the second screw spraying pipe, the slurries in spray system can be made fully to contact with the sulfur-containing smoke gas in spray column, the slurries of circulating pump recycling simultaneously, and by automatic makeup sizing device automatic sizing material supplementing, not only desulfuration efficiency is high; And automaticity is high, reduce the cost of desulfurization process.
