摘要： A method and a device for wet desulfurization of flue gas to remove a sulfur dioxide(SO.sub.2) contained in flue gas discharged from thermal power stations and boilers are disclosed. In the method the device with a gas layered sieve plate for wet desulfurization of flue gas, an absorbing liquid improves reacting conditions by effecting it own circulation without using additional power due to the structural characteristics possessed by the device and flue gas is treated very satisfactorily thanks to high gas-liquid contact efficiency. In order to minimize power consumption and the size of the device but promote desulfurization to an unusual degree, an absorber is divided into an upper froth layer and a lower liquid layer by a single-stage gas dispersing plate with a large number of gas ejection holes bored therein. The absorber comprises a liquid downcomer which enables absorbing liquid which absorbed a sulfur dioxide from the froth layer to overflow when it rises higher than a proper height and then fall by a difference in liquid head produced between the froth layer and the liquid downcomer and a liquid riser which extends downward to a proper length from the gas dispersing plate and enables the absorbing liquid to rise above the gas dispersing plate for ejection to the extent of its fall, and so the absorbing liquid effects its own circulation at a high speed without using additional power. To raise adaptability to changes in boiler load, a number of V notches are formed at regular intervals at the upper end of an overflow weir.

摘要： The present invention provides a method of recycling a spent flue gas denitration catalyst and a method of determining a washing time of the spent flue gas denitration catalyst. The method of recycling the spent flue gas denitration catalyst includes physically removing solids deposited in the spent flue gas denitration catalyst, removing poisoning substances deposited in the spent flue gas denitration catalyst by washing the spent flue gas denitration catalyst with a washing liquid for a washing time determined by measuring the hydrogen ion concentration of the washing liquid and drying the resulting spent flue gas denitration catalyst.

摘要： An improved process and apparatus for production of synthetic multifilamentary yarns having uniform quality. The method comprises extruding a molten synthetic polymer downwardly through a spinneret, advancing the extruded filaments downwardly through a substantially stationary column of heated air, and subsequently advancing the filaments downwardly through a quenching zone wherein they are in contact with cooling air introduced into the path of the filaments under controlled conditions of air velocity and direction of flow. The apparatus for carrying out the process comprises an extrusion spinneret for extruding a number of filaments directly into a heated sleeve having walls that are imperforate, said heated sleeve leading to a quenching chamber having opposite, essentially vertical inlet and outlet panels for allowing cooling air to pass through the chamber, and means for regulating the stream of cooling air whereby both the velocity of the air stream going through the quenching chamber and its general direction as it contacts the descending filaments may be regulated.
