Unburned carbon is efficiently removed from fly ash, and effective utilization of the fly ash and removed unburned carbon is attained. Water is added to fly ash to thereby obtain a slurry. A collector is added to the slurry, and shearing force is applied to the slurry and collector to thereby attain a surface modification. The mixture is subjected to flotation operation at which unburned carbon of fly ash is attached to froths and surfaced. The application of shearing force to the slurry and collector can be carried out by means of a submerged agitator whereby an agitation power of 0.7 to 10 kWh/m3 is applied per unit quantity of slurry. The fly ash concentration of the slurry is in the range of 3 to 50 wt. %, and the amount of collector added is in the range of 5 to 100 wt. % based on the amount of unburned carbon of fly ash. The unburned carbon separated by flotation can be used as fuel, and the fly ash (product) having its unburned carbon content reduced to 1 wt. % or below can be used as a cement mixing material or a raw material for production of lightweight aggregate.

A pressure switch includes an external force transmission mechanism for separating a cover from a housing. The cover and the external force transmission mechanism defines a first pressure chamber, and the housing and the external force transmission mechanism defines a second pressure chamber. In the second pressure chamber, a movable piece having first and second movable members arranged opposite to each other and one or more fixed contacts are disposed. The first and second movable members are connected to each other via a flat spring. A contact is disposed on the second movable member and functions as a movable contact. The external force transmission mechanism applies an external force to the first movable member to displace the first movable member, and the second movable member is reversed at the operating point of the first movable member, so that the movable contact is brought into contact with the fixed contact.

An apparatus for disinfecting containers comprises a disinfection chamber 12 surrounding a required section of a container transport path, partition means for dividing the interior of the disinfection chamber 12 into a preheating zone 35, an exposure zone 36 and a drying zone 37 as arranged downstream from an upstream side of the transport path, antiseptic supply means for supplying hydrogen peroxide gas or mist to the exposure zone 36, and means for supplying hot air to the preheating zone 35 and the drying zone 37.
摘要:
An integrated command definition file defines both names of integrated commands and basic commands integrated. A basic command syntax file stores the basic commands and these parameter information. An integrated command registration utility has functions to convert the integrated command definition to an integrated command syntax file. And an interactive command management module recognizes both of basic commands memorized in the basic command syntax file and integrated commands memorized in the integrated command syntax file.
摘要:
An apparatus and a method for removing unburned carbon from fly ash capable of suppressing facility cost and stably conducting performance adjustment depending on property of the fly ash. The method comprises the steps of: adding water to fly ash to produce slurry; adding collector to the slurry, feeding the slurry and the collector to a static-type mixer 4, a venturi pipe 24 or the like to add shearing force to them; adding frother to them to generate air bubbles; and adhering unburned carbon of the fly ash to the air bubbles to raise the unburned carbon. The frother and air can be fed to the static-type mixer or the like together with the slurry and the collector. Depending on the change in property of the fly ash, the number of the static-type mixers or the like used in series can be increased or decreased, and depending on required capacity, the number of the static-type mixers or the like used in parallel may be increased or decreased. The static-type mixer may comprise a guide vane chamber 4b with plurality of guide vanes 4d for converting the slurry and the like, which are fed to the chamber, to spiral flow, and a current cutter chamber 4c with plurality of mushroom-shaped projections 4e for adding shearing force to the slurry and the like.

An endoscopic forceps is provided. A movable blade electrode and a fixed blade electrode form a pair of electrodes. The fixed blade electrode is electrically contacted onto an external electric conductor of a coaxial cable in the sheath conduit. A force application point of the movable blade electrode is connected to a center electric conductor of the coaxial cable. A pivot point of the movable blade electrode is provided on the movable blade electrode. The coaxial cable is slid with respect to the sheath conduit so that parallel moving added to the coaxial cable is transmitted to the movable blade electrode as turnable moving about the pivot point via the force application point of the movable blade electrode. A high frequency wave can be applied between the movable blade electrode and the fixed blade electrode via the external electric conductor and the center electric conductor of the coaxial cable.

Disclosed is a method for removal of an unburned carbon contained in a fly ash material. The method comprises the steps of adding water to the fly ash to prepare a fly ash slurry; shearing the fly ash slurry using an agitating blade that can rotate at a high speed to generate an active energy on the surface of an unburned carbon by the shearing force, thereby imparting lipophilicity to the unburned carbon; and adding a collecting agent and a foaming agent to the slurry containing the lipophylized unburned carbon to cause the attachment of the collecting agent to the lipophylized unburned carbon, and at the same time, causing the attachment of the unburned carbon having the collecting agent attached thereto an air bubble to separate the unburned carbon by flotation.
