Description

本発明は、発電所等のボイラで発生し、ホッパに蓄積された燃焼灰等を灰輸送管を通して灰処理装置へ吸引輸送するときに、この灰輸送管内に詰った燃焼灰等を崩して円滑に吸引輸送する燃焼灰等の灰輸送管詰り防止装置に関する。   The present invention smooths the combustion ash, etc. clogged in the ash transport pipe when the ash generated in the boiler of a power plant and the like and accumulated in the hopper is sucked and transported to the ash treatment device through the ash transport pipe. TECHNICAL FIELD The present invention relates to an apparatus for preventing clogging of ash transport pipes such as combustion ash that is sucked and transported.

発電所等の大型施設のボイラ等で発生した燃焼灰は、燃焼排ガスと共に脱硝装置及び空気予熱器を経て電気集塵器に導入され、電気集塵器でその大半が捕捉される。電気集塵器の底部には、逆円錐形状のホッパが複数個設置され、捕捉された燃焼灰(EP灰)はこのホッパ内に蓄積される。   Combustion ash generated in a boiler of a large-scale facility such as a power plant is introduced into an electric dust collector through a denitration device and an air preheater together with combustion exhaust gas, and most of it is captured by the electric dust collector. A plurality of inverted conical hoppers are installed at the bottom of the electric dust collector, and the captured combustion ash (EP ash) is accumulated in the hopper.

各ホッパ内に蓄積した燃焼灰は、灰輸送管を通じて真空ポンプで吸引され灰処理装置に輸送される。灰輸送管の一端には大気吸込口が設けられており、この大気吸込口を開き真空ポンプを作動させると、灰輸送管内にはサイロに向けた気流が生じるため、ホッパの下端の排出弁を開くとホッパ内の燃焼灰が灰輸送管に吸引されて輸送される。複数のホッパからの燃焼灰の輸送は、1基ずつ順次排出弁を開いて燃焼灰を吸引することによって行われる。   The combustion ash accumulated in each hopper is sucked by a vacuum pump through an ash transport pipe and transported to an ash treatment apparatus. An air suction port is provided at one end of the ash transport pipe. When the air suction port is opened and the vacuum pump is operated, an air flow is generated in the ash transport pipe toward the silo. When opened, the combustion ash in the hopper is sucked into the ash transport pipe and transported. The transportation of the combustion ash from the plurality of hoppers is performed by sequentially opening the discharge valve one by one and sucking the combustion ash.

例えば、このようなホッパのアッシュインテーク弁(排出弁)を開閉することにより、ホッパ内の重油灰のような燃焼灰が灰輸送管内に落下し真空引きにより温風と共に燃焼灰を輸送する。灰輸送管内に多量の燃焼灰が落下すると燃焼灰の性状、即ち重油灰は粘性が高いので、灰輸送管内に燃焼灰が堆積し閉塞状態となりやすい。   For example, by opening and closing the ash intake valve (discharge valve) of such a hopper, combustion ash such as heavy oil ash in the hopper falls into the ash transport pipe, and transports the combustion ash together with warm air by evacuation. When a large amount of combustion ash falls in the ash transport pipe, the combustion ash properties, that is, heavy oil ash, has a high viscosity, so that the combustion ash tends to accumulate in the ash transport pipe and become blocked.

このような燃焼灰などの詰りを防止する技術として、例えば特許文献1の特開2001−208331号公報「燃焼装置とその煙道灰堆積防止方法」に示すように、燃料を燃焼させるための火炉と、火炉上流側に設けた煙道に設置される火炉に燃料を供給するための燃料搬送用空気を供給する押込通風機及び一次空気搬送用の一次空気通風機と、火炉の上流側の煙道内の空気と火炉の下流側の間に設けられ、煙道内の燃焼排ガスとの熱交換により一次空気と燃料搬送用空気を予熱する空気予熱器と、火炉の下流側の煙道に設けられる火炉からの燃料燃焼排ガス中の除塵をする電気集塵器と、該電気集塵器の上流側のガス流れに沿って登り勾配の傾斜がついた斜行煙道と、該斜行煙道の底部に堆積した灰等を吹き飛ばすため斜行煙道内にパージ媒体を吹き出すノズル及びパージ弁を設置するパージ系統を備えた燃焼装置の煙道灰堆積防止方法において、前記パージ系統に一次空気通風機あるいは押込通風機の下流側煙道から取り出した冷空気に空気予熱器の下流側の煙道より取り出した熱空気を合流させて得られる昇温した空気を用いる燃焼装置の煙道灰堆積防止方法が提案されている。

例えば、前記連鎖状部材(7)は、プーリ(6)に架け渡したチェーンである。前記連鎖状部材(7)は、前記プーリ(6)に架け渡したワイヤ(11)に、部分的にチェーン(10)を連結したものである。
According to the present invention, the combustion ash (A) that accumulates the combustion ash (A) captured by the dust collector and the combustion ash (A) that is connected to the lower end of the hopper (1) and falls from the hopper (1) In order to break down the combustion ash (A) clogged in the ash transport pipe (2) in an ash transport pipe (2) for suction and transport to the ash treatment apparatus (4) An apparatus for preventing clogging of ash transport pipes such as combustion ash is provided, wherein the chain-like member (7) is provided to move back and forth in the ash transport pipe (2).
For example, the chain member (7) is a chain that spans the pulley (6). The chain member (7) is obtained by partially connecting a chain (10) to a wire (11) spanned over the pulley (6).

以下、本発明の好ましい実施の形態を図面を参照して説明する。
図1は実施例1の燃焼灰等の灰輸送管詰り防止装置を示す一部切欠いた概略図である。図2は実施例1の詰り防止装置の一部省略した説明断面図である。
本発明の灰輸送装置は、ボイラの煙道に配置された電気集塵器で捕捉したEP灰等の燃焼灰Aを蓄積するホッパ1は、上端側が広く下端側が狭くなるように形成された漏斗形状をしており、その上部からホッパ1内に粉末状の燃焼灰Aが投入される。ホッパ1の下端近傍には、蓄積した燃焼灰等Aの蓄積物の灰輸送管2への吸引を許容するためのアッシュインテーク弁(排出弁)3が設けられている。なお、このホッパ1は、電気集塵器の下部に複数個複数列に並べられ配置されている。
