Description
本考案は回転する二個の平行に向き合うドラムを上部に単数組または複数組備え、下部にバイオマス燃焼路を備えて一体化した有機汚泥及び有機系廃棄物の処理装置に関するものである。The present invention relates to an organic sludge and organic waste treatment apparatus in which two or more rotating drums facing each other in parallel are provided at the upper part and integrated with a biomass combustion path at the lower part.
下水汚泥の処理は一般的に化石燃料を用いて施設内で焼却処理されるか、外部の処理業者へ処理を委託する等の方法で処理が行われており処理費用がかさむうえ温暖化防止の観点からも好ましい処理方法ではなかった。The treatment of sewage sludge is generally carried out by incineration using fossil fuels in the facility, or by outsourcing to an external processing company, which increases processing costs and prevents global warming. It was not a preferable processing method from the viewpoint.
先行技術として乾燥機を用いて脱水汚泥が自己燃焼可能な含水率になるまで乾燥させたのち補助燃料であるバイオマス燃料とともに焼却し、これらの燃焼熱を利用して蒸気を発生させ、発生した蒸気を乾燥機へ供給して脱水汚泥の乾燥に利用する処理装置がある。（特許文献１）。燃料のエネルギ−を蒸気発生に用い、蒸気のもつエネルギ−で脱水汚泥を乾燥させて処理することは、ボイラの性能に熱効率を左右されやすく、安定して最適な蒸気圧を維持する制御が不可欠でセンサ−類や付属機器等多くの設備を必要とすることから設置面積を相応に確保する必要があることに加え、燃焼熱を直接乾燥に用いる方式より熱効率が落ち、経済性で改善の余地を残す汚泥の処理方法であった。As a prior art, drying is performed until the dehydrated sludge has a self-combustible moisture content using a dryer, then incinerated with biomass fuel, which is an auxiliary fuel, and steam is generated using the combustion heat. There is a processing device that supplies slag to a dryer and uses it to dry dewatered sludge. (Patent Document 1). Using fuel energy for steam generation and drying and treating dewatered sludge with the energy of steam is subject to thermal efficiency depending on the performance of the boiler, and it is essential to control to stably maintain the optimum steam pressure. In addition to requiring a lot of equipment such as sensors and attached equipment, it is necessary to secure a corresponding installation area. In addition, the thermal efficiency is lower than the method of directly using combustion heat for drying, and there is room for improvement in economy. It was a sludge treatment method that leaves
燃料のエネルギ−を蒸気発生に用い、蒸気のもつエネルギ−で脱水汚泥を乾燥させて処理することは、バイオマスボイラの性能に熱効率を左右されやすく、安定して最適な蒸気圧を維持する制御が難しくセンサ−類や付属機器等多くの設備を必要とすることから設置面積を相応に確保する必要があることに加え、排熱を直接乾燥に用いる方式より熱効率が落ち、経済性で改善の余地を残す汚泥の処理方法であった。Using the energy of the fuel for steam generation and drying and treating the dewatered sludge with the energy of the steam makes it easy to control the thermal efficiency depending on the performance of the biomass boiler, and the control to stably maintain the optimum steam pressure. In addition to the fact that it requires a lot of equipment such as sensors and accessories, it is necessary to secure a corresponding installation area. In addition, the heat efficiency is lower than the method using exhaust heat directly for drying, and there is room for improvement in terms of economy. It was a sludge treatment method that leaves
そこで、本考案は、蒸気を介在させることなく脱水汚泥の処理を行うことで、処理過程において必要とされるバイオマス補助燃料を減らすとともに、処理過程において捨てられていた排熱の有効利用をはかれるコンパクトで経済的な処理装置を提供する。Therefore, the present invention reduces the biomass supplementary fuel required in the treatment process by treating the dewatered sludge without intervening steam, and can make effective use of waste heat discarded in the treatment process. Provide economical processing equipment.
本考案の処理装置は、上記の目的を達成するため、次の手段を採った。すなわち、ダブルドラムを上部に備え、上部から二個のドラム面が平行して向き合う箇所へ脱水汚泥を落とし込む部分にスライドして供給口を開閉する二枚の仕切り板を設け炉の内部と外部が必ず該仕切り板のいずれかに仕切られた状態で脱水汚泥を投入する構造とし、ドラム面で乾燥した汚泥をかきとるスクレパ−をドラム各面に備え、下部にバイオマス燃焼炉を備えて一体化した。In order to achieve the above object, the processing apparatus of the present invention employs the following means. In other words, a double drum is provided at the top, and two partition plates that open and close the supply port by sliding the dewatered sludge into the part where the two drum surfaces face each other in parallel from the top are provided. The dewatered sludge is always put in a state of being divided into any one of the partition plates, and scrapers for scraping the sludge dried on the drum surface are provided on each surface of the drum, and a biomass combustion furnace is provided at the bottom for integration. .
回転する二個の平行に向き合うドラムを上部に複数組備え最上部に位置する組の二個のドラム面が平行して向き合う箇所へ上部から食品残渣や製紙スラッジ、飲料水メーカなどで出るお茶の出涸らしやコーヒーカスのような非貼着性の有機系廃棄物を落とし込む部分にスライドして供給口を開閉する二枚の仕切り板を設け炉の内部と外部が必ず該仕切り板のいずれかに仕切られた状態で被処理物を投入する構造としドラム面で乾燥した被乾燥物をかきとるスクレパーを各ドラム面にそれぞれ設け下部にバイオマス燃焼炉を備えて一体化した。A set of two rotating drums facing each other at the top, and the top two sets of drum surfaces facing each other parallel to each other, the top of the food residue, paper sludge, drinking water maker, etc. Two partition plates that open and close the supply port by sliding to the part where the non-adhesive organic waste such as dumplings and coffee scum are dropped are provided, and the inside and outside of the furnace must be partitioned into one of the partition plates. A scraper for scraping off the material to be dried on the drum surface was provided on each drum surface, and a biomass combustion furnace was provided at the lower part and integrated.
蒸気を介在させないので、最適に蒸気圧を制御する難しさがなく、簡便にシステムを運用できる。Since no steam is present, there is no difficulty in optimally controlling the vapor pressure, and the system can be operated easily.
センサーや付属機器の数が少なくて済み、コンパクトで経済的。Small number of sensors and accessories, compact and economical.
燃焼炉内で乾燥と焼却の両方の処理を行うことで、熱損失を限りなく減らして下水汚泥の焼却処理をすることができるので排熱を分散することなく効率的に回収できる。By performing both drying and incineration in the combustion furnace, heat loss can be reduced as much as possible, and sewage sludge can be incinerated, so that exhaust heat can be efficiently recovered without being dispersed.
被処理物をコンベアー等で搬送する工程が存在しないことから悪臭が作業場内にこもることがなく、作業環境に優しい。Since there is no process for transporting the object to be processed by a conveyor or the like, bad odors are not trapped in the work area and are friendly to the work environment.
被処理物を装置外で別途加工運搬する工程が存在しないことから、それらの加工、運搬に必要とされる装置が不要である。Since there is no process for separately processing and transporting the object to be processed outside the apparatus, an apparatus required for such processing and transportation is unnecessary.
ドラムの形態は特に限定しないThe form of the drum is not particularly limited
バイオマス燃焼炉については連続して燃料を供給し、連続運転のできるものであれば特にその形態を限定しない。The form of the biomass combustion furnace is not particularly limited as long as the fuel is continuously supplied and continuous operation is possible.
