Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to description word to make those skilled in the art.
As depicted in figs. 1 and 2,
Be applicable to a dust arrester for industrial waste gas, comprise:
First cylindrical shell 1, it is arranged on the first support 110, described first cylindrical shell 1 is bottom is provided with the first air entry 120, top is provided with the first gas outlet 130 the first cavity structure, be spaced from top to bottom in described first cylindrical shell 1 and be provided with multiple filter group 140, each described filter group 140 comprises the first filter 141, filtering material layer 142 and the second filter 143 from top to bottom successively, described first filter 141 is provided with the first through hole that multiple diameter is the circle of 20nm, and described second filter 143 is provided with the second through hole that multiple diameter is the circle of 18nm;
Second cylindrical shell 2, it is arranged on the second support 210, described second cylindrical shell 2 is provided with the second air entry 220 for bottom, the second cavity structure of the second gas outlet 230 is located at top, the dividing plate 240 that surface uniform offers multiple third through-hole is provided with in described second cylindrical shell 2, described second cavity structure is divided into the clean chamber being positioned at top and the cleaning chambers being positioned at below by described dividing plate 240, described dividing plate 240 Surface coating has thickness to be the waterproof ventilated membrane of 1mm, described second cylindrical shell 2 sidewall sets gradually two baffle plates 250 from top to bottom, described baffle plate 250 to round setting along described second cylindrical shell 2 madial wall, itself and side wall lower ends are 30 °, discharge outlet 260 is offered bottom described second cylindrical shell 2, described discharge outlet 260 is communicated with a water tank 3 by pipeline, the height of described second support 210 is higher than the height of described water tank 3,
Air blast 4, its one end connects the first gas outlet 130 by flexible pipe, the other end connects the second air entry 220 by flexible pipe, described air blast 4 is set to air to be drawn in described first cavity from described first air entry 220, and by described air via described first gas outlet 130 air blast to the second air entry 220;
