Description

  The present invention relates to a processing apparatus that allows used paper diapers to be carbonized to be recycled into reusable resources.

  Currently, about 206,000 tons of disposable diapers are produced for children and 134 thousand tons for adults. After use, the weight is about 4 to 5 times that before use, so about 1030,000 tons for children and about 670,000 tons for adults, a total of 1700,000 tons are incinerated as waste. By the way, incineration treatment causes problems such as disposal sites for dioxins and incineration ash, and emission of carbon dioxide. This contributes to environmental problems and global warming, and immediate recycling is essential.

So now as a recycling method,
1) After crushing used paper diapers, pulp is separated and recovered to obtain recycled paper, and sewage is treated with microorganisms and used as a soil conditioner.
2) A used paper diaper is heated to a high temperature and carbonized, and the carbide is used as a fuel.
Such a method has been proposed. The latter method has a shorter processing time and can be processed at a lower cost than the former method. The present invention provides a processing apparatus useful for this latter method.
Japanese Patent Laid-Open No. 2000-313884

  The problem to be solved by the present invention is to deal with used paper diapers that solve these conventional problems and carbonize used paper diapers in a short time so that reusable resources can be recycled at low cost. To provide an apparatus.

The configuration of the present invention that solves this problem is as follows.
1) A crusher is provided to crush used paper diapers into small pieces, a sterilization chamber is provided to sterilize the fine pieces crushed by the crusher with a stirrer, Disposal equipment for used paper diapers, characterized in that it has a carbonization chamber equipped with an electric heater that heats from the surroundings to a high temperature under reduced pressure. 2) The sterilization chamber sprays ozone on the strips to be stirred. The used paper diaper processing apparatus according to 1), which is provided with an ozone spreader 3) The ozone spreader is an electric ozone spreader that generates and spreads ozone using electricity. 4) Used paper diaper processing apparatus 4) The used paper diaper processing apparatus according to any one of 1) to 3) above, wherein an ultraviolet irradiation device for irradiating ultraviolet rays onto a strip heated by an electric heater is provided in the carbonization chamber. 5) Stir while heating the strip in the carbonization chamber The used disposable diaper processing apparatus according to any one of 1) to 4) above, wherein the heating temperature of the strip is in the range of 400 to 700 ° C. It is in the processing equipment of used paper diapers.

  According to the present invention, a used paper diaper is pulverized into small pieces by a pulverizer, the pulverized fine pieces are stirred by a stirrer and heated from the surroundings to a high temperature by a heat generator, and the moisture of the fine pieces evaporates. Reduce to 5-15% and carbonize. As described above, according to the present invention, it is possible to provide a used paper diaper processing apparatus for carbonizing a used paper diaper in a short time to obtain a reusable recycled resource.

  The stirrer of the present invention is provided with an ozone spreader for spraying ozone (O3) in order to sterilize bacteria in water splashed from the strip being stirred. As the ozone spreader, an electric type, a chemical type, or the like is used, and a range of 25 to 150 ppm is practical as a spray amount. Since the chemical formula O3 is immersed in water and kills benign fermenting bacteria, the electric formula is more convenient because the post-treatment washing in the room is anxious and excess O3 disappears due to natural decomposition in the air stream.

  As the carbonization chamber, a container-like one heated by an electric heater and heated uniformly from the surroundings is used. Is practical. The heating machine may be provided with stirring blades for stirring in order to uniformly heat the strips and carbonize them. Embodiments of the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is an explanatory diagram of a used paper diaper processing apparatus according to an embodiment. In the figure, 1 is an apparatus body, 2 is an inlet, 3 is a pulverizer, 4 is a stirring chamber, 5 is a geared motor, 6 is a stirrer, 7 is an electric ozone spreader, 8 is a gate, 9 is a heat generator, 10 is a stirring blade, 11 is a UV lamp, 12 is a gate, 13 is a chute, 14 is an ozone generator, 15 is a compressor, 16 is an electric heater, 17 is a control panel, 18 is a container, C is carbide, p is used A paper diaper, s is a strip.

  As shown in FIG. 1, the processing apparatus of this embodiment is provided with a loading port 2 for loading a used paper diaper p at the top of the apparatus body 1, and the used paper diaper p loaded below the loading port 2 is made into a strip. A crusher 3 to be crushed is attached, a stirring chamber 4 is provided below the crusher 3, a stirrer 6 that is rotated by a geared motor 5 having a plurality of sharp blades is provided in the lateral direction, and above the stirrer 6. An ozone spreader 7 for sterilizing the strip s being stirred is attached.

  A gate 8 for discharging the crushed pieces s is provided at the bottom of the stirring chamber 4 so as to be opened and closed by an air cylinder (not shown). A container-like heat generator 9 is provided at the discharge destination of the pieces s. A stirring blade 10 for stirring the strip s to be heated is rotatably provided by a motor (not shown), and a UV lamp 11 for irradiating ultraviolet rays to the strip s to be heated is attached above the heat generator 9. A chute 13 that opens and discharges carbide C at the gate 12 is provided on the lower side surface.

  In addition, the apparatus body 1 is provided with an ozone generator 14 for supplying ozone to the electric ozone spreader 7, a compressor 15 for supplying compressed air to the air cylinders (not shown) of the gate 8 and the gate 12, and the heat generator 9. An electric heater 16 for heating is provided, and a control panel 17 for controlling each device is provided.

  In this embodiment, when the used paper diaper p is charged into the charging port 2, it is pulverized by the pulverizer 3 into strips s having a particle size of about 5 to 25 mm and falls into the stirring chamber 4 below. In the stirring chamber 4, the stirrer 6 is rotated 6 times per minute by the geared motor 5, and ozone is sprayed in an amount of 100 ppm per minute by the ozone spreader 7. The fallen pieces s are stirred by the stirrer 6. While being sterilized and disinfected uniformly with ozone, it is stored at the bottom.

  When a certain amount of strip s is stored at the bottom of the stirring chamber 4, the gate 8 is opened and the strip s is fed into the heat generator 9 by its own weight. The inside of the heat generator 9 is heated to about 500 ° C. by the electric heater 16 and the stirring blade 10 is rotated 6 times per minute, and is fed into this high temperature atmosphere and the strips s are stirred at a high speed from the surroundings. Heated uniformly and completely carbonized in approximately 3-5 hours. Thereafter, the carbide C is taken out from the outside of the apparatus main body 1 to the container 18 by the chute 13.

  Since the present embodiment is configured in this manner, the carbide C taken out of the used disposable diaper p is reduced to 100/1 to 100/3 by volume and 100 / 0.5 to 100/5 by weight. It was done. The time required for the treatment was 0.5 hour / kg. Since this carbide C is heat-treated at a high temperature of about 500 ° C., it has no bacterial growth and almost no odor, and is effectively reused as a fuel, a deodorizing material, a soil improving material, and the like.

  The present invention is mainly used for used paper diapers, but is not limited thereto, and can be applied to hygiene articles such as urine collection pads, incontinence pants, napkins, liners, and tissues.

It is explanatory drawing of the processing apparatus of the used paper diaper of an Example.
