    Abstract: The present invention relates to a loop-route production method and system for polyvinyl chloride, and belongs to the intersecting fields of coal chemicals, polymer materials and chemical machinery. Limestone and carbon materials such as coal are reacted in an oxygen-enriched high temperature furnace to obtain calcium carbide and carbon monoxide, and then acetylene and carbon monoxide are respectively produced from calcium carbide and dichloroethane (obtaining ethylene, etc., through methanol or ethanol); both of the end products are combined to form a closed-loop; acetylene and dichloroethane are reacted to produce a vinyl chloride monomer, which is polymerized to obtain polyvinyl chloride. The system of the present invention mainly includes a device for pulverizing and mixing solid raw materials, a device for conveying solid materials, an oxygen-enriched calcium carbide furnace, an oxygen-enriched air-blowing device, a tube-shell thermostatic reactor, a fixed bed tubular reactor, a fluidized bed reactor, an acetylene generator having a heat exchanger, a fixed bed reactor and a polymerization reactor, The present invention has the advantages of not only removing the dependence on oil resources during the production of polyvinyl chlorides, but also totally eliminating the mercury pollution.

    Abstract: Shutoff device for hollow electrodes supplying particulate feed material to and/or removing furnace gas from electrothermal reduction furnaces, arc melting furnaces, e.g., calcium carbide or similar furnaces. The inner shell of the hollow electrode has an inclined pipe socket secured to it, preferably welded thereto, which in turn has detachably secured to it a sleeve with an inflatable bag therein. The bag is displaceable by means of a thrust rod from inside the sleeve to a position inside the hollow electrode, and inflated therein using gas under pressure to effect shutoff of the hollow electrode.

    Abstract: 987,256. Mounting of electric furnace electrodes. KNAPSACK-GRIESHEIM A.G. Jan. 10, 1962 [Jan. 10, 1961], No. 938/62. Heading F4B. A cover for an electric furnace has apertures for the electrodes, and includes a number of portions in the form of sectors, to each of which an electrode is allotted, the cover being adjustable to vary the inter-electrode spacing by radial shifting of the sectors. Sectors 1, 2, 3 have electrode apertures 4, 5, 6, and may be moved radially outwards to increase the interelectrode spacing. The gaps 10 are bridged by flanged insulating bricks, and movable cover portions 7, 8 and 9 may be provided. Specification 979,642 is referred to.
