摘要:
A method for removing nitrogen oxides and organic chlorine compounds from a combustion waste gas, which comprises the steps of: adding ammonia (NH.sub.3) as a reducing agent to a combustion waste gas containing nitrogen oxides and organic chlorine compounds; causing the combustion waste gas added with ammonia to contact with, while keeping the temperature of the combustion waste gas within a prescribed range, with a catalyst comprising at least one selected from the group consisting of platinum (Pt), palladium (Pd), ruthenium (Ru), manganese (Mn), copper (Cu), chromium (Cr) and iron (Fe) and oxides thereof, supported on the surface of a carrier comprising at least one selected from the group consisting of titanium oxide (TiO.sub.2), silicon oxide (SiO.sub.2), aluminum oxide (Al.sub.2 O.sub.3) and zirconium oxide (ZrO.sub.2), thereby removing nitrogen oxides and organic chlorine compounds from the combustion waste gas.
摘要:
A method for removing detrimental organic chlorine compounds such as polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans from a combustion waste gas, which comprises the steps of: bringing organic chlorine compounds contained in a combustion waste gas at a temperature within a range of from 150.degree. to 350.degree. C. into contact with a catalyst comprising at least one selected from the group consisting of platinum, palladium, ruthenium, manganese, copper, chromium and iron and oxides thereof, which catalyst is supported on the surface of a carrier containing at least titanium oxide, Aluminum oxide and silicon oxide, to cause a decomposition reaction of the organic chlorine compounds, thereby removing organic chlorine compounds from the combustion waste gas at a high efficiency.
摘要:
The present invention discloses a method of controlling combustion of a fluidized-bed incinerator. In a fluidized-bed incinerator (5), a method of controlling combustion of the fluidized-bed incinerator comprises measuring a supply rate of incineration waste by a supply rate measuring unit (11) using a photoelectric element (1) arranged on a shoot (2) for supplying incineration waste (3) from a dust feeder (4) to the incinerator (5), and when the supply rate of incineration waste is higher than a predetermined value, decreasing a supply rate of incineration waste of the dust feeder 4 to suppress a combusting operation, increasing an induced gas rate of an exhaust gas induced blower (9) of the incinerator to suppress an increase in an incinerator internal pressure decreasing a flow rate of fluidizing air of a forcing blower (7) to suppress a combusting operation, or increasing a flow rate of a blower (8) for supplying air to a free board portion to prevent production of an unburnt gas.
摘要:
The present invention relates to a method of measuring a supply rate of incineration waste in a fluidized-bed incinerator.The method is characterized in that a passing state of incineration waste ( 3) is detected by an photoelectric element ( 1) arranged on a chute ( 2) for supplying the incineration waste from a dust feeder (4) to an incinerator (5), and a rate of waste (w) is calculated from a detection signal from the photoelectric element in accordance with the following equation: ##EQU1## where w: supply rate of waste per unit time; m: the number of photoelectric elements; t: detection signal time per unit time; T: unit time; and A: constant.
摘要:
The instant invention relates to a method for culturing and floating animal cells in a double-bag container, where an outer bag containing culture media and a volume of air houses an inner bag of a semipermeable film containing cells suspended in a culture media. The semipermeable film has pores of sufficient size so as to prohibit cells within the inner bag from passing therethrough but allowing culture liquid and air to pass through it. To optimize the exchange of nutrients between the interiors of the two bags, a protective mesh surrounds the inner bag and the double-bag container is fastened to an agitator which provides either a rotating or shaking motion.
