专利汇可以提供Cleaning pollutants from furnace and incinerator smoke and the like专利检索，专利查询，专利分析的服务。并且A means for cleaning pollutants from moving gases, such as furnace and incinerator smoke, comprising conducting the gas through a cleaning zone passage of substantial length defined by an encompassing wall from which washing liquid is sprayed to form a dense shower of the washing liquid so that the gas is continuously washed as it progresses through the shower.，下面是Cleaning pollutants from furnace and incinerator smoke and the like专利的具体信息内容。
2. Apparatus according to claim 1, in which said orifices in the extremity of said upstream portion of said passage are directed generally normal to said axis upstream from said orifices which direct the streams generally diagonally downstream.
3. Apparatus according to claim 1, including orifices upstream from said orifices which direct the streams generally diagonally downstream, said upstream orifices being disposed to direct the streams therefrom diagonally generally upstream.
4. Apparatus according to claim 1, including orifices in the downstream extremity area of said downstream portion of said passage disposed to direct The streams therefrom generally normal to the passage axis.
5. Apparatus according to claim 1, comprising orifices in the upstream extremity area of said upstream portion of said passage disposed to direct streams therefrom generally normal to said axis, followed by orifices located immediately downstream which are disposed to direct the streams therefrom generally diagonally upstream relative to said axis, followed by said orifices disposed to direct the streams generally diagonally downstream.
6. Apparatus according to claim 5, including orifices in the downstream extremity area of said downstream portion of said passage disposed to direct the streams therefrom generally normal to the passage axis.
7. Apparatus according to claim 1, in which said wall is of generally bulbar form with the narrowest ends adjacent to the ends of said upstream and downstream portions and with the widest dimension at said intermediate portion.
8. Apparatus according to claim 7, said wall having a cylindrical portion at the upstream end thereof.
9. Apparatus according to claim 7, said wall having a cylindrical portion at the downstream end thereof.
10. Apparatus according to claim 7, said wall having respective cylindrical terminal portions at the upstream and downstream ends thereof.
11. Apparatus for cleaning pollutants from moving gas and especially adapted for cleaning potential air pollutants from furnace and incinerator smoke, comprising: means providing a cleaning zone passage having its axis generally horizontal and being of substantial length defined by an encompassing wall and through which gas with pollutants is adapted to be conducted as a continuously moving flow; a spaced jacket about said wall providing a washing liquid supply chamber; said wall being perforate to provide orifices located at closely spaced points in substantially the entire ambit and length of said wall to drive spray streams of washing liquid toward said axis; said orifices being disposed to direct said streams generally diagonally downstream in an upstream portion of said passage, generally normal to said axis in an intermediate portion of said passage and generally diagonally upstream in a downstream portion of said passage whereby the spray streams impinge and glancingly strike one another and thereby disperse the spray streams into a gas-permeable dense shower of the washing liquid completely across and substantially throughout the length of the passage to assure thorough washing of the flowing gas as it progresses along the passage through the shower; means for supplying the washing liquid to said chamber under pressure to drive the liquid through said orifices to provide said spray streams; said wall having a low point therein generally centrally along the length of said passage toward which spent washing liquid is adapted to flow from each end of the passage; a drain leading from said low point through said supply chamber and said jacket and sealed from said supply chamber; said means for supplying the washing liquid including a duct communicating with said supply chamber through said jacket spaced from said drain.
12. Apparatus according to claim 11, including means for cleaning and recirculating the spent washing liquid from said drain through said duct.
