〔産業上の利用分野〕
本発明は発電ボイラに堆積した灰塵を回収する装置に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for recovering ash dust accumulated in a power generation boiler.
ボイラ運転時に発生する灰塵は、時日の経過に伴って煙
道内面に付着堆積し、煙道内壁の腐食の原因となり、さ
らに通風性に障害を来すので、定期的に除去する必要が
ある。Ash dust generated during boiler operation accumulates on the inner surface of the flue over time, causing corrosion of the inner wall of the flue and impeding ventilation, so it must be removed regularly. .
従来の付着灰塵除去方法としては、煙道内でやぐら状に
足場を築き、作業員が竹はう自等で掻き落とし友後、煙
道の底部にたまった落灰を、作業員が運べる程度に少量
づつ袋詰めにして煙道外へ搬出していた。The conventional method for removing adhering ash dust is to build scaffolding in the shape of a tower inside the flue, and after scraping off the fallen ash with a bamboo crawler or the like, the fallen ash that has accumulated at the bottom of the flue is removed to the extent that the worker can carry it. Small amounts were packed into bags and transported out of the flue.
従来は人的作業に頼っているため、次のような問題点が
あった。Conventionally, since it relied on human work, there were the following problems.
１） 飛灰、高所、高温、暗黒等による悪い作業環境の
ため、作業時間が限られ、作業能率が低い。1) Due to the poor working environment due to fly ash, high places, high temperatures, darkness, etc., working time is limited and work efficiency is low.
２） 作業員が高所かつ暗黒な場所で安全に作業するた
めの準備等に長時間を要する。2) It takes a long time to prepare for workers to work safely at high places and in dark places.
３） 人的な作業の丸めどうしても灰塵の取り残しが生
ずる。3) Rounding of human work inevitably leaves some ash behind.
本発明は前記問題点を解決するために、煙道内に同煙道
の長手方向に沿って敷設されたレールと、同レールの上
を移動可能な台車と、問合手段および吊上げ吊下す手段
とを具え九ことを特徴とする灰回収装置を提案するもの
である。In order to solve the above-mentioned problems, the present invention includes a rail laid in a flue along the longitudinal direction of the flue, a cart movable on the rail, an inquiry means, and a lifting means. The present invention proposes an ash recovery device having the following features.
ルト≠÷中によって台車近傍に掻き寄せ、空気吸引装置
によって吸収し、吸引ホースを通して煙道外へ排出し回
収する。また、この落灰の排出回収は台車をレール上を
煙道の長手方向に移動させながら連続的に行なう。It is scraped up near the trolley by the route, absorbed by the air suction device, and discharged out of the flue through the suction hose to be collected. Further, the discharge and collection of this fallen ash is carried out continuously while moving the cart along the rail in the longitudinal direction of the flue.

In these figures, (1) is the bottom of the inner circumferential wall of the flue, (2) is the rail laid along the longitudinal direction of the flue, (3) is the rack attached to the rail (2), and (4) is the bottom of the inner peripheral wall of the flue. ) is a trolley movable on the rails, (5) is a guide row 9 that is attached to the trolley (4) and guides the trolley (4) by pinching the rail (2), (6) is a truck drive unit that is attached to the truck (4) and moves the truck (4) while meshing with the rack (3) attached to the rail (2), (η is an air suction device mounted on the truck (4)) , (8) is a suction hose for sending the ash sucked in by the air suction device (7) to the outside of the flue, and (9) is connected to the suction port of the air suction device (7) to remove the ash accumulated at the bottom. A suction nozzle (lO) for suctioning is attached to the above-mentioned cart (4) and extends toward both sides across the above-mentioned rail (2) to remove the ash collected at the flue bottom (1). 9) A pair of brush belts that scrape nearby, (11
) A roller motor for rotating the flage belt (lO), (12) a hanging wire for lifting the toothbrush belt, and (13) a small winch for hoisting and lowering the hanging shear wire (12).
次に本装置の作用について説明する。Next, the operation of this device will be explained.
