摘要： PURPOSE: To provide a wet process production unit designed to make a FRP sheet with improved resin dispersibility and fiber orientation by running a foamed dispersion containing fibers and thermoplastic resin particles in compliance with the axially symmetrical revolving flow inside a manifold and then delivering the dispersion via plural distributive outlets into a head box. CONSTITUTION: In conducting a wet process making of a FRP sheet, reinforcing fibers such as glass fibers and thermoplastic resin particles such as of polypropylene are added to a foamed liquid to prepare a foamed dispersion, which is then fed via an inlet 21 into a manifold 20 vertically downward along the center axis Y and guided to the axially symmetrical curved surface of the inner shell, and the dispersion of uniform concentration run in compliance with the axially symmetrical revolving flow induced by a turbine-type horizontal rotary agitator 24 having an agitating shaft 24a coinciding with the center axis Y is delivered via the respective distributive outlets 25 plurally arranged concentrically on the upper part of the manifold 20 into a head box and then fed onto a mesh belt to make a web with a wet process.

摘要： PURPOSE:To improve the efficiency in recovering of waste heat by forming small chambers in the side wall parts on the inside surfaces of an upper hood, dividing the waste gas after passing through red hot sintered ore to the waste gas in the small chambers and the high temp. waste gas in the central part of the trough and recovering heat from the latter alone. CONSTITUTION:The waste gas of a boiler 5 supplied from the lower part of a trough 3 through a lower header 2 is heat-exchanged with the layers of red hot sintered ore 4 to the high temp. waste gas. In this case, part of the waste gas passing through the parts near the side edge parts on both sides of the trough 3 is sucked into small chamber 6 in a negative pressure state and is discharged together with the atmospheric air entering through clearances 11 to the outside of the system by the effect of a suction fan 20. On the other hand, the waste gas past the ore 4 in the central part of the trough 3 is introduced through an upper hood 1 then through a duct 8 and a dust remover 9 into the boiller 5 without the influence of the intruding air. In the boiler the waste heat is effectively utilized in generating steam; thereafter, the waste gas is mixed with the cold wind through a cold wind valve 21, and is circulated to the header 2 with a circulation fan 6.

摘要： PURPOSE: To arbitrarily control mechanical strength in a specific direction while easily changing the orientation state of a reinforcing fiber by continuously supplying a surfactant-containing aq. dispersion containing the reinforcing fiber, a thermoplastic resin and water to the forming surface of a porous support moved while the inclination of the forming surface with respect to a horizontal plane in an advance direction is changed. CONSTITUTION: A discontinuous reinforcing fiber and a thermoplastic resin are dispersed throughout a surfactant-containing aq. dispersion containing fine air bubbles in a dispersing tank 1. This dispersion is supplied to the surface of the belt like porous support 3 continuously moved through a headbox 2. The headbox 2 has a ceiling plate 23 inclined low forwardly and the dispersion is supplied into the headbox 2 from a rear lower part supply pipe 21. Herein, the inclination of the forming surface 3a of the porous support 3 is inclined when the dispersion of the reinforcing fiber and the thermoplastic resin is supplied to the forming surface 3a and the flow state of the dispersion on the forming surface is controlled to control the fiber orientation state in a formed web, that is, the directionality of mechanical characteristics.

摘要： PURPOSE:To keep the high oxidation ratio of CO and to enhance effect for largely conserving energy and reducing operation cost, by simultaneously performing the oxidizing action of CO and the regeneration of a deteriorated catalyst. CONSTITUTION:In a method for regenerating a catalyst used in the oxidation of CO in exhaust gas, oxidizing catalysts 5a, 5c having high activity are arranged in the upstream side of an exhaust gas flowline and deteriorated oxidizing catalyst 5b, 5d are arranged in the downstream side to perform oxidation of CO and the catalysts in the downstream side perform not only the oxidation of CO remaining in the exhaust gas issued from the catalyst beds in the upstream side but also the regeneration of the catalyst deteriorated by said gas. By this method, the high oxidation ratio of CO can be kept and the replacement of the catalyst or the high temp. heating of exhaust gas is dispensed with while CO contained in exhaust gas is oxidized perfectly. As a result, the entire amount of heat of CO-oxidation can be utilized in the regeneration of the deteriorated catalyst and effect for largely conserving energy and reducing operation cost can be enhanced.
