摘要:
A full spectrum light emitting lamp and one or more translucent base bodies surrounding the lamp are disposed in the lighting apparatus, the one or more translucent bas bodies having a photocatalytic reaction layer which bears a photocatalyst made of a titanium dioxide thin film therein, or the one or more translucent base bodies having the photocatalytic reaction layer which bears the photocatalyst made of the titanium dioxide thin film therein and having infrared light-absorbing functions, and a space through which air can flow is formed between the lamp and the translucent base body. Therefore, an ultraviolet light, a visible light and an infrared light can effectively be utilized according to characteristics such as an air purifying function of the ultraviolet light, a lighting function of the visible light, and a heating function of the infrared light to thereby save optical energy emitted from the lamp. Further, forced convection is generated in the air flow space by a heating effect of the infrared light emitted from the lamp in addition to a heating effect of the optical energy emitted from the lamp, so that the air can sufficiently be ventilated to promote an air purifying effect.

The object of the invention is to provide a polymerization processor from a raw material in a molten state, which can synthesize a polymer of high quality. Lactide sent from an apparatus for supplying lactide 1 is heated and molten in an apparatus for melting lactide 2, and a catalyst is added to the lactide in an apparatus for supplying a catalyst 3. The molten lactide is supplied through an apparatus for supplying lactide 4 to a horizontal reaction tank 5, and flows by a head difference with a polymerization reaction proceeding. A discharged reaction solution is supplied to the upper part of a vertical reaction tank 6, and flows through the vertical reaction tank 6 by gravity with the polymerization reaction proceeding. Thereafter, the reaction solution is transported to an apparatus for removing remaining lactide 7, where unreacted lactide is removed, and then the reaction solution is discharged.

Radioactive laundry liquid wastes are supplied in a liquid waste heating vessel. Hydrogen peroxide and an alkali solution are supplied to the liquid waste heating vessel. pH of radioactive laundry liquid wastes is adjusted to 7 or higher by the alkali solution. The radioactive laundry liquid wastes are heated to 50° C. or higher by a heating device. The heated radioactive laundry liquid wastes are introduced to first and second aeration vessels. Ozone is supplied from an ozone generator by way of an ozone gas discharge port to the first aeration vessel. Ozone discharged from the first aeration vessel is introduced from the ozone gas discharge port to the second aeration vessel. Therefore, the amount of ozone dissolved into the radioactive laundry liquid wastes is increased so that the amount of hydroxy radicals formed for decomposing organic substances increases, since the laundry liquid wastes are heated to 50° C. or higher under the presence of hydrogen peroxide.

摘要:
An equipment for producing polyhydroxycarboxylic acid, includes a ring-opening polymerization apparatus, a liquid phase devolatilizing apparatus, and a drying apparatus, wherein an indirect heat exchanger is connected to a vent gas discharge path of the liquid phase devolatilizing apparatus. The indirect heat exchanger captures a dispersed in-process substance containing hydroxycarboxylic acid cyclic dimers and transfers the substance to the ring-opening polymerization apparatus; a wet condenser and a hot well are connected to a vent gas discharge path of the indirect heat exchanger and that of the drying apparatus, respectively. The wet condenser captures a dispersed in process substance containing the cyclic dimers with the use of a refrigerant containing hydroxycarboxylic acid corresponding to the cyclic dimers and transfers the substance to the hot well; the hot well causes hydrolysis of the cyclic dimers for generation of hydroxycarboxylic acid; the generated hydroxycarboxylic acid is mixed with a refrigerant and the mixture is circulated to the wet condenser; and hydroxycarboxylic acid is highly concentrated via circulation between the wet condenser and the hot well and then discharged.
