专利汇可以提供Device and method for removing pollutants from stack gases专利检索,专利查询,专利分析的服务。并且Apparatus for removing smoke particles and water soluble combustion gases from stack gases, e.g., of roofing tar heaters and supermarket incinerators, having a body shell in which the stack gas is directed upwardly around at least three vertically aligned and centrally disposed baffle elements, each defining an annular space between the periphery thereof and the body shell, an associated peripheral deflector skirt for each baffle element positioned slightly thereabove and baffling the annular space thereabout and being contiguous to the body shell, a horizontally disposed array of downwardly directed steam nozzles positioned between the associated baffle element and deflector skirt combination above the lowest most baffle element and deflector skirt, and a similar array of water nozzles between the uppermost baffle element and deflector skirt combination, the stack gas exiting from the body shell to a chimney pipe. Each of the peripheral deflector skirts, and each of the baffle elements except the lowest one, are formed of foraminous metal shells such as perforated metal and filled with an activated adsorbent material such as activated anthracite, the lowest most baffle being imperforate. Drains are provided in the floor of the body shell and preferably lead the steam condensate and collected water spray to a filter unit from which water is recycled to the water nozzles. Additional scrubbing capacity is provided by either or both of placing opposed water sprays in the chimney pipe or by utilizing a fourth baffle element and peripheral skirt combination between the water sprayed and steam sprayed combinations, such fourth combination being either steam sprayed or water sprayed as may be required. The method of removing smoke particles and soluble combustion gases from stack gases comprises leading the stack gas through the apparatus described while utilizing little more than sufficient steam in combination with the activated adsorbent to absorb and remove visible smoke particles and enough water to take up the steam but insufficient to interfere seriously with the draft, and collecting the scrubbed materials in the condensed steam and the water and draining them out of the apparatus, preferably to a filter unit from which recycle water is obtained.,下面是Device and method for removing pollutants from stack gases专利的具体信息内容。
