摘要:
An improvement in a method of pyrolysis wherein an organic material, such as city waste, is pyrolyzed using a two-bed type pyrolysis system including a fluidized bed type pyrolysis reactor and a combustion reactor and wherein energy is recovered from burning the pyrolysis gases produced is disclosed. The improvement comprises recovering the heat of a combustion exhaust gas which is generated when the energy of the pyrolysis gas is recovered, heating a fluid medium with the recovered heat, and heating the organic material to be pyrolyzed with the heated fluid heat medium to dry the organic material before it is pyrolyzed.
摘要:
A method for safely and continuously pyrolyzing organic material such as contained in municipal waste is presented for use in a two-bed pyrolysis system primarily comprising a pyrolysis reactor and combustion reactor in which several different physical factors influencing the state of fluidization such as amount of sand in the system, circulation rate of the sand, pressure difference between the free boards of the two reactors and superficial velocity in the pyrolysis reactor, are comprehensively controlled or regulated so as to maintain the operating point of the system at substantially the center of the stable operating range. The feed rate of material charged into the system may also be regulated as required.

摘要:
A method and a system for disposing of the pyrolysis gas generated in a pyrolyzing system to refine the same are presented in which an absorbing agent for eliminating harmful gas is introduced into a thermal reactor in such an amount that a large percent of such agent is unreacted but it is efficiently recovered together with char from the pyrolysis gas and also these recovered materials are utilized to remove oil and tar from water used in cleaning the pyrolysis gas, the recovered solid particles of the char and unreacted absorbing agent and the oil and tar separated from the cleaning water being recirculated in the pyrolyzing system.
摘要:
A pyrolyzing apparatus having a pyrolysis fluidized bed chamber and an incineration fluidized bed chamber or chambers each directly adjacent and communicated with the pyrolysis fluidized bed chamber through an opening or openings in a partition wall above a common perforated bottom plate, the respective levels of the fluidized beds being controlled by regulating the pressure(s) in free board(s) of the fluidized bed chambers.
摘要:
Anti-falsification paper characterized in that thin fragments having brightness, which are obtained by fragmenting nacreous pigment coated paper coated with a nacreous pigment coating solution mainly comprising a nacreous pigment and a binder insoluble in cold water but soluble in hot water, are allowed to exist near the surface of a substrate sheet. Even when falsification is attempted by reproduction using a color copying machine, the colors of the thin fragments having brightness, which are mixed in paper, cannot be reproduced. Therefore, a genuine (original) can be easily distinguished from a forgery (copy). The thin fragments are firmly bonded to paper by the action of the binder, and fall-off of the thin fragments does not occur at the time of printing. Even when anti-falsification paper becomes spoilage or waste paper, thin fragment with brightness does not adversely affect recovery of the pulp.
摘要:
A cable is previously introduced into a pipe in which the cable is to be laid. A wagon is caused to move through the pipe and the cable is raised up with the aid of an arm disposed at the fore part of the wagon until it abuts against the inner wall of the pipe. The cable is then fixed to the inner wall of the pipe by using fixing means disposed at the rear part of the wagon.
