1results about How to "Develop circular economy" patented technology

The utility model relates to a kind of multi-stage water spray's dust tail gas washing tower, exhaust fan, dust tail gas washing tower, washing water storage tank are sequentially communicated, washing water spray pipeline and multi-stage spray water pipeline are respectively communicated with the middle and top of dust tail gas washing tower, backflush pipeline is connected with dust tail gas washing tower bottom and tower bottom liquid discharge pipeline respectively in two ways, dust tail gas washing tower bottom is communicated with washing water storage tank by liquid discharge pipeline;Washing water spray pipeline and multi-stage spray water pipeline are respectively provided with regulating valve group.The advantage lies in, the utility model uses original washing water spray pipeline and newly added multi-stage spray water pipeline to carry out multiple washing recovery to dust in tail gas, washing water after dust washing enters washing water storage tank by liquid discharge pipeline for other production process to use again, not only conducive to reducing production site dust accumulation and reducing dust explosion risk, but also conducive to increasing yield and reducing consumption, developing circular economy.
