Industrial Systems - Hitachi

1 The 21st century is the Century ofEnvironment calling for a radical shift inour approach toward the environmentfrom consumption to recycling. Hitachistrives to contribute to the sustainabledevelopment of our society andimprovement of the quality of life throughthe maximum use of skill, experience,and know-how accumulated as a resultof Hitachi s work to improve our society sinfrastructure from factories, recreationalfacilities, highways, and hospitals torailway stations, scientific researchlaboratories, vehicles, and Systems52 Industrial SystemsKiln-type gasification/melting system pilot plant(Hitachinaka City, scale of process: 20 t/d)Dioxin precursormonitorExhaust gasFlueEntrance pipeSamplingboxA view of the CP-2000 dioxin precursor monitorEmissions of dioxins from refuse incinerators have become aserious social problem.

2 In response to this problem, regulations willbe introduced in December 2002, and measures to reduce theseemissions are now underway. However, one of the main obstaclesto such measures is the difficulty in directly measuring theconcentration of dioxin in emission gas. A way to overcome thisdifficulty is, instead, to measure the amount of precursor gas (thatis, chlorophenols) interrelated with the dioxin , the CP-2000 Dioxin Precursor Monitor has beendeveloped for real-time, on-line measurement of thesechlorophenols. This novel monitor incorporates atmosphericpressure chemical ionization (APCI) and a three-dimensionalquadrupole mass spectrometer (3-D QMS) and provides highsensitivity in the order of several tens of parts per trillion.

3 As well asproviding high-speed continuous measurement (it takes less than aminute) of chlorophenols, it is anticipated that the monitor will helpin developing guidelines to specify the most suitable combustioncontrol conditions for dioxin reduction developed a next-generation waste-treatment systemthat is environmentally friendly and that allows for the maximumexploitation of waste is indirectly heated in a gasification furnace in an oxygen-free state at 450 to 500 C and is broken down into cracking gasand cracking residue (char). Because cracking gas contains littlechlorine, soot, and dust, it can contribute to energy saving by beingused as heating fuel.

4 As for the char, unoxidized metal is collected(recycled) and the remaining char is sent to a melting furnace forswirling combustion at 1,300 to 1,400 C to render the ash moltenand harmless when it is used as a heat source. At the same time,the system significantly reduces generation of dioxins by high-temperature combustion and cuts down the dioxin concentration inwaste gases to ng-TEQ/m3(N) or less. Also, it generates high-temperature and high-pressure steam to enable highly efficientpower generation by combining melting-furnace exhaust heat andcracking-gas exhaust this system allows for the gasification furnace andmelting furnace to be operated separately, the gasification furnacecan also be used as a carbonized-fuel system .

The condition of existing networks istherefore continuously changing. Accordingly, a new optical-fiber-cable management system for accurate and efficient maintenanceof all the fibers (from 24- up to 1,000-fiber optical-fiber cables) inthese networks has just been system provides a fiber management function to managethe status of a huge amount of deployed fiber in conjunction withgeographical data and a fiber monitoring function for monitoringfiber-cable features of the system are:(1) PC system configuration for easy operationThe client/server configuration enables the system to be flexiblyexpanded and easily operated.

Records of past,present, and predicted fiber data are embedded in drawing data sothat data of a certain time can be rapidly retrieved and manipulated.

7 Fiber-connection diagrams are automatically drawn according totheir connection positions within junction boxes enablingcomplicated fiber-connection information to be accurately andrapidly obtained. By using these diagrams to manage each branchpoint ( , junction box) in the fiber network, the system can easilyhandle rapid increases and configuration changes in managedfibers as a result of branching.(4) Rapid and accurate detection of fiber faults and automaticmap display of the failure locationFiber faults in cables with spare fiber capacity can be time domain reflectometer (OTDR) monitors spare fibers,and when a fault occurs, it automatically detects the fault locationand displays it on a monitor.

8 (5) Fiber route trackingA fiber route is specified from the start point to its terminus;therefore, to find the best route to meet the specification, thesystem tracks all fiber routes and can rapidly identify open routesand available fiber routes.(6) Fiber reservationA user-reservation function for individual fibers facilitates fiberlending and installation management.
