Title: Moving bed type apparatus for denitration reaction
Inventor: FUKAZAWA HARUO
IPC: B01D53/94
Filed: 1980-03-12
Abstract: PURPOSE:To prevent the degradation in the activity of catalysts and the occurrence of dew point corrosion based on the temp. drop of the catalysts by heating the moving catalysts with a part of high-temp. waste gas in reducing and denitrating the waste combustion gas contg. NOx with NH3 by utilizing a moving catalyst bed. CONSTITUTION:NH3 gas is added from an NH3 injector 13 to the NOx-contg. waste gas G1 exhausted from a combustion device 1 such as boiler from the way of a pipeline 16. The NH3-mixed waste gas is sent by a fan 2 into a denitration reactor 3, is subjected to reduction denitration of NOx by NH3 in the catalysts moving therein from above to below and is exhausted as a denitrated gas G2. The catalysts move in the reactor 3 from above to below and are again circulated and supplied from the lower part of the reactor 3 to the upper part by a conveyor 7. At this time, part G3 of the high-temp. waste gas is taken out before it enters the reactor 3, is passed in the conveyor 4 to heat the catalysts and is again returned into the pipeline 16. Since the catalysts are heated, their temp. drop in dead spaces 4, 5 does not occur, hence the degradation of their activity and the dew point corrosion owing to moisture condensation are prevented.

Title: High atmospheric-pressure gas laser device
Inventor: KAWAKUBO YUKIO
IPC: H01S3/038
Filed: 1985-02-20
Abstract: PURPOSE:To eliminate a reaction with halogen gas, and to emit a stable output for a prolonged time by coating the whole surface of a conductor as a current flow path contributing to the generation of an electric field with an insulator in a device in which an induction electric field with a change with time at high speed of large currents is utilized as a method of pre-ionization. CONSTITUTION:Since a U-shaped tabular current path 4 is folded back at minute distances, an intense magnetic-flux density change (-)B/(-)t proportional to a current regulation dI/dt is generated, thus generating a strong electric field E along a current path 6. Since one part of a laser gas is ionized by the strong electric field E, uniform discharge is acquired in the whole space when discharge is started between main electrodes 7 by a main discharge capacitor 5 at the next point of time. Since slits 8 are formed to the U-shaped tabular current path 4, pre-ionized electrons can easily disperse into a main discharge space, and equal discharge is obtained easily. Since the whole surface of a conductor is coated with an insulator in the U-shaped tabular current path 4, the conductor hardly reacts with halogen gas, thus reducing the deterioration of the gas.
