  • Patent number: 6949226
    Abstract: A sodium-based dechlorinating agent is added to a flue gas; hydrogen chloride contained in this flue gas is removed as residue of dechlorination; the thus removed residue of dechlorination is dissolved by adding water; water-insoluble constituents are separated from the resulting aqueous solution; and after adjusting pH of the aqueous solution remaining after separation of the water-insoluble constituents, mercury, dioxin, and the like are removed and discharged. The sodium-based dechlorinating agent is mixed with a hydrophilic anti-caking agent, with an angle of repose of 40° or more, a dispersibility of less than 50, and a floodability index value of less than 90. This permits inhibition of occurrence of a pressure drop and leakage in the filter cloth of the dust collector.

  • Patent number: 6834938
    Abstract: The present invention provides an ink jet recording apparatus in which many components in a carriage-driving system are unitized into a carriage frame. The apparatus comprises a carriage loaded with a recording head for discharging ink from a plurality of nozzles, a carriage-driving device for driving the carriage, a bendable electric wire, and a carriage frame. The electric wire is bent from an apparatus body and mounted to the recording head and passes a printing signal to the recording head. The carriage frame arranges the carriage, the carriage-driving device, the recording head, and the electric wire at predetermined positions to form a unit. The carriage can reciprocate in parallel with the main scan direction along the longitudinal direction of the carriage frame. As a result, the recording head can be easily replaced, and the apparatus can be maintained without complicated work.
