Filed: 1992-12-14
Abstract: PURPOSE:To prevent seizure of a throttle valve so as to ensure smooth operation of the valve by monitoring always the relationship between the openings of two throttle valves located in an intake-air pipe in a series connection so that the volume of EGR (exhaust gas recirculation) is continuously and gradually decreased when a condition in which intake air counterflow is established within the intake-air pipe. CONSTITUTION:With the duty control of solenoid valves 18, 19 by an ECU (electronic control unit) 6, a drive pressure which is intermediate between an intake negative pressure at a position 20 of an intake-air passage 1 and the atmospheric pressure at a position 21 of an intake-air passage 1 is fed into an upper chamber of an actuator 16. Further, an EGR control valve 17 is opened so as to adjust the volume of EGR fed into the intake-air pipe 1 from an opening 15 through an EGR passage 14. In this case, the opening degrees of two throttle valves 27 connected in series and located in the intake-air passage 1, are detected by throttle sensors 5, 9 so as to always monitor the relationship therebetween. As a result, when a condition in which counterflow of intake-air occurs, is established, the volume of EGR is continuously decreased, or the EGR is stopped.

Filed: 1993-12-27
Abstract: PURPOSE:To sharply reduce the amount of sludge generated in a waste water treatment process to make small a waste water treating device, and also to simplify the process, and further to make good use of coal resources. CONSTITUTION:Waste gas including gaseous SO2 and a coal slurry are subjected to gas-liquid contact to absorb the gaseous SO2 into the coal slurry, and a calcium sulfite slurry formed by the absorption reaction is oxidized to produce gypsum. When the calcium sulfite slurry drawn from a pH conditioning column 2 and temporarily stored in a raw liquid tank 5 is sent to an oxidation device 6 to oxidize it by air, a lime slurry is fed into the raw liquid tank 5 to increase the pH of the liquid. The fed quantity of the lime slurry is controlled so that the pH of a gypsum slurry formed by oxidation reaction may be 7-8. Thus, the pH of separated water of a gypsum thickener 7 is kept within an effluent standard to eliminate the necessity of making its neutralization treatment on discharge.

CONSTITUTION:A catch basin 1 is composed of a three-way joint 2 and an inspecting cylinder 3, and a cover 4 is installed on the upper end of the inspecting cylinder 3. In the cover, an inclined surface whose central part 42 is high and becomes low toward a peripheral part 43 is provided, and a grip 41 is added. When a clogging condition of an upstream side port 21 or a downstream side port 22 is inspected, a cover 71 of a protective cage 7 and the cover 4 of the inspecting cylinder 3 are removed, and the inside is inspected. At this time, in an upper surface of the cover 4, the central part 42 is high and the peripheral part 43 is low, so that rainwater fallen until inspection is not collected on the upper surface. Thereby, even if this upper surface gets wet, since it dries up at once, earth and sand do not stick to this upper surface. Thereby, the cover 4 can be opened without feeling unwell. Since a boundary between the cover 4 and the inspecting cylinder 3 exists on a side surface, it can be simply opened without clogging earth and sand in a clearance of this boundary.
