    摘要: A wet exhaust gas desulfurization apparatus includes a housing, an absorbing solution (3, B) stored in the lower portion of the housing, a flue (1, 2, 11, 12, 21, 25) above the surface of the absorbing solution, and a partition plate (4, 15, 25) for dividing the flue into gas inlet and outlet portions. Exhaust gas is introduced as an untreated combustion gas from a space above an absorbing solution (3) divided by a partition plate (4) into the wet exhaust gas desulfurization apparatus, the lower edge (5) of the partition plate is immersed in the solution, pressure of the exhaust gas lowers the upper level (6) of the solution on the upper side of the plate to a level (6') through which the gas passes and flows under the partition plate in contact with the solution leaving the solution on the other side of the plate and then discharges through a space above the absorbing solution on the other side of the partition plate. The plate may be raised and lowered by a rack (4') and pinion ( 4") device, and water jet devices (29) may be used to wash absorbing solution off the surfaces (27, 28) of the plate continuously or intermittently.

    摘要: A fuel injector to be mounted on a branch of an engine intake manifold has a hollow body with an injection orifice therein and a valve member mounted slidably in the body and having a pintle extending from one end of the valve member and slidably received in and extending through the injection orifice. A sleeve member is mounted on the body to cover the injection orifice and defines a pintle-receiving space into which the forward end of the pintle extends. Communication apertures are formed in the outer end of the sleeve member to communicate the pintle receiving space with an engine intake passage. The total of the cross-sectional areas of the communication apertures is smaller than the cross-sectional area of the pintle-receiving space.

    摘要: A method for controlling the concentration of a slurry in an absorption tower in which a flue gas comprising SO.sub.2 is brought into contact with a slurry containing suspended Ca compounds therein to absorb the SO.sub.2 with the compounds. The method comprises withdrawing the slurry from the absorption tower in such a way that the slurry is divided into at least two groups with different concentrations, one group being a slurry having a higher concentration of the Ca compound, the other group being a slurry having a lower concentration of the Ca compound, and regulating rates of the slurries being withdrawn from the absorption tower whereby the concentration of the Ca compound in the slurry being contacted with the flue gas is controlled.

    摘要: A process for treating an exhaust gas discharged from a coal combustion apparatus, in which the exhaust gas is first led to a dry type dust collecting device, and after fly ash in said exhaust gas is removed, said exhaust gas is treated by a wet type exhaust gas cleaning device; a part of said fly ash collected in said dry type dust collecting device is added to a discharge liquid or a discharge sludge discharged from said wet type exhaust gas cleaning device. The amount of the fly ash to be added to the discharge sludge should be at least three times (in weight) as much as the amount of water contained in said discharge sludge. Preferably fly ash of approximately the same weight as that of said discharge sludge should be added to the discharge sludge discharged from said wet type exhaust gas cleaning device, and subsequently calcium hydroxide of about one-tenth in weight of said discharge sludge should be added to the mixture for solidifying said discharge sludge. In a preferred embodiment, the mixture of the discharge liquid and the fly ash is led to a solid-liquid separator to separate the mixture into clear water and sludge, and the clear water is returned to said wet type exhaust gas cleaning device, while the separated sludge is mixed with additional fly ash to further eliminate a discharge water.
