It has been a long time since this issue was screamed, but it is well known that after that, these issues have been earnestly studied in various fields, and countermeasures have been gradually taken and implemented.
Recently, attempts have been made to recycle the above wastes and use them as fuels, and some of them have been put into practical use. Recycling of these wastes into fuels means that wastes can be effectively used, and energy resources In terms of helping to secure this, the social significance is particularly great, and it is drawing attention from various fields. In recent years, the composition of wastes has changed, and a large amount of high-calorific polymer materials such as plastics are now included. For example, general municipal wastes contain 80 to 90% of solid organic matter and plastics. The substance is said to contain about 10%. Therefore, it is not difficult to imagine that reusing this as fuel by some means will have a great effect from the viewpoint of waste treatment and energy resource conservation.

FIG. 1 is a flow chart showing an outline of the manufacturing method of the present invention, FIG. 2 is a vertical cross-sectional view of a partially cutaway portion of an extruder, and FIG. It is a perspective view of the manufactured solid fuel. That is, the present invention comprises a step (A) of pulverizing various solid organic wastes containing a polymer substance into a pulverized product, and drying or humidifying the coarsely pulverized product so that its water content is 8 to 15% (weight). And a step (C) of extruding the water-adjusted coarsely crushed product at a pressure of 600 kg / cm 2 or more. In the extrusion molding step (C), In the method for producing a solid fuel by making the polymer substance into a semi-molten state by compression heat and acting like a binder, the extrusion molding step (C) comprises primary extrusion by a spiral feed blade around a rotating drum, By the eccentric disc that co-rotates on the tip surface of the rotary drum at a position eccentric from the axis of rotation, the die-shaped passage radially provided around the tip surface of the rotary drum is subjected to strong compression of 600 kg / cm 2 or more. Is carried out with the secondary pressing It is a method for producing a solid fuel from the solid organic waste characterized by. Various solid organic wastes which are the starting materials of the present invention, that is, industrial wastes including combustible wastes or general municipal wastes, do not necessarily vary depending on the place of occurrence, season, etc., but contain about 10% of plastic substances. The composition of general waste in recent years in Tokyo is 80 to 90% of combustible materials such as papers, plastics and fibers,
20 to 10% of non-combustible materials such as metals, glasses and ceramics
Is said to be. In order to obtain a solid fuel by the manufacturing method according to the present invention using such waste as a raw material, as shown in the figure, the above-mentioned incombustibles are removed by primary crushing in advance before the coarse crushing step (A), and then known. The raw material is roughly crushed by the crusher of No. 3 to make a lump or a granule (including a powder) having a maximum length of 30 mm or less. It is preferable that the maximum length of the coarsely crushed product be 30 mm or less in view of workability in the extrusion molding step (C) described later and quality control of the product. Ie 3
If it exceeds 0 mm, the load of the extruder becomes large and the extruder becomes inoperable, and the product becomes brittle, and it may become impossible to maintain a solid state. Next, in the water content adjusting step (B), the water content is adjusted to 8 to 15% by drying or humidifying. When the water content is less than 8%, the solidification tends to be insufficiently achieved in the extrusion molding step (C), and when it exceeds 15%, the calorific value of the product as a fuel decreases due to the latent heat of vaporization of water. . The waste material is where it is generated,
Since the water content varies depending on the temperature, humidity, etc., either drying or humidification is required here to adjust the water content, but drying is done with an ordinary dryer and humidification is simply done by adding an appropriate amount of water and kneading. Just do it. The raw material whose water content has been adjusted as described above is continuously extruded in the next extrusion step (C). FIG. 2 shows an example of an extruder used in the step (C). The extruder has a spiral feed blade 2 on the circumference.
1 and a rotating drum 2 having an eccentric disc 22 capable of rotating at the end and being axially supported by the main body 1 described below, and supporting the rotating drum 2 and surrounding the periphery thereof, and feeding the raw material to the upper part on the driving side. A plurality of die dies 12, which have a hopper 11 and which can be attached radially over the entire circumference of the maximum trajectory drawn by the eccentric disc 22 as the rotary drum rotates, are fixed in parallel, and the die dies are fixed. The main body 1 is provided with a guide frame 13 on the discharge side of 12 ... The raw material fed from the hopper 11 is fed by the rotation of the rotary drum 2 to the feed blade 2
By the action of 1, it is sent to the side of the sequential die 12 ..., where it is compressed by the primary pressing of the feed blade 21. The compressed raw material is further extruded continuously from the die passages 121 of the die dies 12 arranged side by side while being strongly compressed by the eccentric disc 22 that rotates in cooperation with the rotary drum 1 as a secondary pressure. . The continuously extruded compacts are broken by the guide frame 13 provided so as to intersect the extrusion direction of the die dies 12 ..., and the rectangular solid fuel 3 shown in FIG.
Can be made continuously. When pressed by the eccentric disc 22 against the die molds 12, a pressure of 600 kg / cm 2 or more is applied to the raw material and heat of compression of 250 to 300 ° C. is simultaneously generated. Due to this heat of compression, the polymeric substances contained in the raw material become semi-molten, and lignin etc. in the wood are eluted, and these act in cooperation with the action of water in the above-mentioned adjustment range, and the raw material particles (agglomerated / powdered material) Evenly) to become an effective binder capable of binding the particles to each other. Here, when the pressing force by the eccentric disc 22 is less than 600 kg / cm 2 ,
Since the heat of compression as described above cannot be obtained, and the effect of the binder is reduced, the product becomes brittle and easily broken. It is needless to say that this pressing force is greatly affected by the rotation speed of the drum 2 and the amount of raw material charged, and therefore the number of rotations and the amount charged should be appropriately adjusted according to the nature of the waste to be treated.
The solid matter obtained in this way varies from 5500 to 7500 Kcal / kg, depending on the type of waste.
It becomes an excellent solid fuel having a calorific value of.
尚、上記押出成形工程（Ｃ）の後、成形品は上述の如く

本図に限られるものではないことは云うまでもない。After the extrusion molding step (C), since the molded product retains the compression heat as described above, the molded product is easily ignited. Therefore, it is preferable to cool the molded product forcibly or by allowing it to stand before filling or packing. Further, the above primary pulverization is not always necessary when it is known in advance that the waste material to be treated does not contain foreign substances such as iron, glass, and ceramics. Further, one example of the extruder adopted in the present invention is shown in FIG. 2, but the extruder is not limited to this figure as long as it is an extruder of this kind so that the extrusion pressure is 600 kg / cm 2 or more. Needless to say.

である。In the above-mentioned structure, the solid fuel production method of the present invention has the greatest advantage in that all the solid organic substances in the waste are treated and it becomes an extremely useful solid fuel.
In other words, not only municipal solid waste but also industrial waste can be regenerated as solid fuels by the method of the present invention except for incombustible waste, which has been a serious social problem than before. The fact that the essentially worthless material is transformed into a valuable entity as a heat source as the treatment is effectively performed means that the effect is extremely large. In addition, it is no exaggeration to say that the method of the present invention helps to open up the prospect for the difficulty of securing future energy resources due to the limit of oil reserves. It is said that the industrial development promotes the increase of wastes more and more, and it is said that the wastes which are the raw materials of such solid fuels are inexhaustibly created. In addition, since the process of the present invention is extremely simple as described above, the labor required for it is low, the manufacturing cost is low, and the product obtained with a safe and compact structure is excellent in energy saving, and the product is excellent in shape retention and is robust. Therefore, it is convenient for transportation and other handling. Therefore, it is widely used as a heat source for boilers and drying ovens.

In the method of producing a solid fuel by becoming a semi-molten state by acting as a binder, the extrusion molding step (C) involves the primary pressing by the spiral feed vanes around the rotary drum and the tip surface of the rotary drum. By the eccentric disc that rotates in a position eccentric from the axis of rotation, the dies are formed in a die-type passage radially provided around the tip surface of the rotary drum.
A method for producing a solid fuel from solid organic waste, which is carried out by secondary pressing with strong compression of 00 kg / cm 2 or more.
