摘要： PROBLEM TO BE SOLVED: To provide a catalyst supporting bag filter capable of removing dust or a harmful gas component contained in exhaust gas stably and efficiently over a long period of time even if backward washing operation is repeated. SOLUTION: In the catalyst supporting bag filter (1), from which adhered dust is shaken off by the jet fluid from a backward washing nozzle, for removing dust and a harmful gas component contained in exhaust gas, the support amount of a catalyst of the range of 10-40% of the total length of the bag filter from the upper end part, where the backward washing nozzle is positioned, of the bag filter is at least 1.3 times that of other part. In a method for manufacturing the catalyst supporting bag filter (2), the range of 10-40% of the total length of the bag filter from the upper end part of the bag filter, which is impregnated with a catalyst-containing liquid, is further impregnated with a catalyst-containing liquid the concentration of the catalyst of which is 1-1.5 times that of the catalyst-containing liquid and the support amount of the catalyst of the impregnated range is made at least 1.3 times that of the other part.

摘要： PROBLEM TO BE SOLVED: To enable the stable supply of a carrier to be used for an agrochemical preparation at a low cost. SOLUTION: Combustion ash obtained by burning fine coal is pulverized and classified to collect fine powder having an average particle size of =80 deg.C for at least 30 min to elute iron and alkali metals which are exposed on the surface of the coal ash. After holding it at the temperature for at least 30 min, the mixture is subjected to solid-liquid separation to collect the solid component (combustion ash), the resultant solid component is optionally subjected to acid neutralization with alkali, washing with water and so on, and the product is used in an agrochemical preparation as an agrochemical carrier.

摘要： PROBLEM TO BE SOLVED: To efficiently reduce toxic components such as nitrogen oxides(NOx), dioxins(DXNs), etc., in the flue gas of a refuse incineration furnace. SOLUTION: In the refuse incineration equipment provided with a refuse incineration furnace 1, a cooling device 3 for the flue gas, a deduster 5 for the flue gas of the incineration furnace, an ash melting furnace 11 melting incinerated ash 8 separated by the deduster 5 for the flue gas, and a deduster 15 for the flue gas of the melting furnace, a catalist-carrying bag filter 5 is used as the deduster for the flue gas of the incineration furnace and a bag filter 15 is used as the deduster for the flue gas of the melting furnace. Alkali metals in the flue gas of the melting furnace are removed by the bag filter for the melting furnace flue gas and acidic substances in the flue gas of the melting furnace are removed by the bag filter 15 for the melting furnace flue gas by blowing an acidic substance-removing agent 17 in the upstream of the bag filter for the melting furnace flue gas. In this way, the flue gas passing through the bag filter for the melting furnace flue gas is returned 19 to the upstream of the catalyst-supporting bag filter 5 for the incineration furnace flue gas to simultaneously treat the nitrogen oxides and organic chlorine compounds.

摘要： PROBLEM TO BE SOLVED: To efficiency reduce heavy metals such as Hg in a waste gas of a trash incinerator and also to reduce the amount of an additive used in a waste gas treatment to the atmost. SOLUTION: A filter assistant and Hg absorbent using least one kind among powders of a diatomaceous earth, alumina, silica and activated carbon large in specific surface area as a carrier and carrying ZnI2 as an active component is used as an absorbent of the heavy metal such as Hg. A soot and dust on a bag filter 4 is rapidly peeled and a clogging of the soot and dust at an inside of the bag filter 4 is prevented since the heavy metal absorbent is the filter assistant as well. Also, a quantity to be treated of the ash is reduced and a treating method is simplified as compared to a case at which each assistant is added since the absorbent is a combined assistant. The soot and dust the heavy metals such as Hg are blown off by a pulse jet or a back washing operation together with the Hg absorbent on the surface of the bag filter 4 when a filter back pressure more than a fixed value is generated by depositing the soot and dust on the bag filter 4.
