厨芥処理システムで粉砕厨芥を配管移送するためには、粉砕厨芥を十分な移送媒体中に分散させて低濃度スラリ−として流動させる必要がある。ところで、厨芥を厨芥粉砕手段に予め投入し、粉砕運転を開始する従来の厨芥破砕手段では、運転開始時に集中的に厨芥粉砕物が発生し、極めて高濃度のスラリ−を形成し、
配管内の流動性を阻害する。そこで、粉砕開始時の粉砕速度を遅くし、運転初期の高濃度スラリ−形成を回避した。粉砕速度の制御は、厨芥粉砕をモ−タ−を利用して行う場合は回転数制御により可能となる。
In order to transfer the crushed kitchen by piping in the kitchen waste processing system, it is necessary to disperse the crushed kitchen waste in a sufficient transfer medium and flow it as a low-concentration slurry. By the way, in the conventional kitchen crushing means in which the kitchen shavings are put into the kitchen shavings crushing means in advance and the crushing operation is started, the kitchen shavings are intensively generated at the start of the operation to form an extremely high concentration slurry.
It hinders the fluidity in the piping. Therefore, the crushing speed at the start of crushing was slowed down to avoid the formation of high-concentration slurry at the initial stage of operation. The crushing speed can be controlled by controlling the number of revolutions when crushing the kitchen waste using a motor.
また、厨芥の粉砕速度は厨芥の処理量や厨芥の粉砕し易さ等の厨芥の性状によっても異なる。そこで、厨芥破砕手段に厨芥の投入処理量、粉砕し易さなどの厨芥情報の検知手段および／もしくは厨芥の粉砕速度を検知する手段を設け、該検知手段からの情報で厨芥粉砕速度をスラリ−が高濃度にならないように可変制御するものとした。厨芥粉砕をモ−タ−を利用して行う場合はモータ−への供給、消費電気の情報、トルク等を検知することで厨芥情報が得られる。厨芥粉砕速度は、厨芥量の時間変化情報等から得られる。移送供給媒体の供給速度も厨芥の粉砕速度に合わせて、制御し、スラリ−濃度が高濃度にならないように、あるいは稀薄となり、過剰なエネルギ−消費を招かないように適正化するものとした。
In addition, the crushing speed of the kitchen waste varies depending on the properties of the kitchen waste such as the amount of the kitchen waste processed and the ease of crushing the kitchen waste. Therefore, the kitchen crushing means is provided with a means for detecting kitchen information such as the amount of processing of the kitchen waste and the ease of crushing, and / or a means for detecting the crushing speed of the kitchen waste, and the information from the detecting means is used to reduce the kitchen waste crushing speed. Is variably controlled so that the concentration does not become high. When crushing the kitchen waste using a motor, the kitchen waste information can be obtained by detecting the supply to the motor, the information on the electricity consumption, the torque, and the like. The kitchen waste crushing speed can be obtained from the time change information of the amount of kitchen waste. The supply rate of the transfer supply medium was also controlled according to the crushing rate of the kitchen waste, and optimized so that the slurry concentration did not become high or diluted and excessive energy consumption was not caused.
また、厨芥破砕手段に接続される配管の縦管部では、粉砕厨芥と移送媒体のスラリ−は、固形物と液体に分離する傾向があり、縦管長さが長いほど、分離が顕著となる、これは、液体は管壁を伝い流れするのに対し、固体は管中を落下するためである。固液の分離は、縦管終了後の横管部で閉塞を招く。そこで、厨芥破砕手段を設置する時に、該厨芥破砕手段に接続される配管の縦管部長さ、材質、管径、継ぎ手構造、横管部の管径、勾配ほかの設計情報で、粉砕速度、特に粉砕開始時の速度の設定値を可変調整して、高層階に設置される厨芥粉砕手段から排出される粉砕厨芥スラリ−濃度を低く保ち、縦管での固液分離による配管閉塞の危険性を回避した。
Further, in the vertical pipe portion of the pipe connected to the kitchen waste crushing means, the crushed kitchen waste and the slurry of the transfer medium tend to separate into a solid substance and a liquid, and the longer the vertical pipe length, the more remarkable the separation. This is because the liquid flows down the pipe wall, while the solid falls in the pipe. Separation of solid and liquid causes blockage in the horizontal pipe after the end of the vertical pipe. Therefore, when installing the kitchen waste crushing means, the length, material, pipe diameter, joint structure, pipe diameter of the horizontal pipe, slope and other design information of the pipe connected to the kitchen waste crushing means are used to determine the crushing speed. In particular, by variably adjusting the set value of the speed at the start of crushing, the concentration of crushed kitchen slurries discharged from the kitchen crushing means installed on the upper floors is kept low, and there is a risk of pipe blockage due to solid-liquid separation in the vertical pipe. Was avoided.
