【発明の詳細な説明】 〔産業上の利用分野〕 本発明は熱交換器の伝熱管を洗浄する洗浄体を捕集す
るための洗浄体捕集装置に係り、特に、洗浄体補修装置
の上流側に偏流が生じている場合であっても、洗浄体を
有効に捕集することが出来る洗浄体捕集装置に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning element collecting device for collecting a cleaning element for cleaning a heat exchanger tube of a heat exchanger, and in particular, upstream of a cleaning element repairing apparatus. The present invention relates to a cleaning body collecting device capable of effectively collecting a cleaning body even when a drift occurs on the side.
従来の洗浄体捕集装置は、実開昭60−38393号公報に
示されるように、熱交換器から排出される冷却水の流路
に設置され、熱交換器の伝熱管の内面を洗浄するために
流される洗浄体を捕集するものである。そして、冷却水
を流す胴体と、冷却水を通し洗浄体を集める格子部材
と、洗浄体を抽出する抽出管とを有する。As shown in Japanese Utility Model Application Laid-Open No. 60-38393, a conventional cleaning body collecting device is installed in a flow path of cooling water discharged from a heat exchanger and cleans an inner surface of a heat transfer tube of the heat exchanger. This is to collect the washing body that is washed away. And it has a body which flows cooling water, a lattice member which collects washing bodies through cooling water, and an extraction pipe which extracts washing bodies.
また、第2図に示す洗浄体捕集装置(特公昭52−1186
62号公報参照)は、胴体1の内部に傾斜して形成された
格子部材2を有する。格子部材2で集められた洗浄体
は、格子部材2上を転動し、洗浄体の抽出管6から取出
される。なお、格子部材2は回転軸3を中心に動く。Further, a cleaning body collecting device shown in FIG. 2 (Japanese Patent Publication No. 52-1186)
No. 62) has a lattice member 2 formed to be inclined inside a body 1. The cleaning body collected by the grid member 2 rolls on the grid member 2 and is taken out from the extraction pipe 6 of the cleaning body. Note that the grid member 2 moves about the rotation axis 3.
例えば,第2図に示すように冷却水を洗浄体捕集装置
に導く配管が、曲部を有する入口曲管7の場合には、冷
却水の偏流が発生する。偏流が発生すると、冷却水と共
に流れてきた洗浄体は、抽出管6の方向に転動せず、洗
浄体の回収が困難であつた。For example, as shown in FIG. 2, when the pipe for guiding the cooling water to the cleaning body collecting device is an inlet curved pipe 7 having a curved portion, drifting of the cooling water occurs. When the drift occurs, the cleaning body flowing together with the cooling water does not roll in the direction of the extraction pipe 6, and it is difficult to collect the cleaning body.
このため、入口曲管7のような偏流が発生し易い配管
が洗浄体捕集装置に連接する場合には、偏流を押える目
的で整流板9が入口曲管7の内部に設置されていた。な
お、符号8は出口曲管である。For this reason, when a pipe such as the inlet curved pipe 7 that is likely to cause drift is connected to the cleaning body collecting device, the rectifying plate 9 is provided inside the inlet curved pipe 7 for the purpose of suppressing the drift. Reference numeral 8 denotes an outlet curved pipe.
しかしながら、第2図に示されるような整流板は、曲
部を有する配管の内部に設置されるため、製作上困難で
あり高価なものであった。安価にするために直線的な配
管を用いて冷却水を整流しようとすると、直線的な配管
部分が長くなり、狭隘なプラントには設置出来ないとい
う問題があつた。However, since the current plate shown in FIG. 2 is installed inside a pipe having a curved portion, it is difficult and expensive to manufacture. If straightening piping is used to rectify the cooling water in order to reduce the cost, the length of the straight piping becomes long, and there is a problem that it cannot be installed in a narrow plant.
そこで、本発明の目的は、洗浄体捕集装置の胴体の内
部で冷却水の偏流を抑制するような洗浄体捕集装置を提
供することにある。Therefore, an object of the present invention is to provide a cleaning body collecting device that suppresses the drift of cooling water inside the body of the cleaning body collecting device.

を抽出する抽出管とを有するものである。The cleaning body collecting device of the present invention is provided in a flow path of cooling water discharged from a heat exchanger, and collects a cleaning body flowing for cleaning an inner surface of a heat transfer tube of the heat exchanger. hand,
A body through which the cooling water flows, a cooling body through which the cooling water flows, and a cleaning member are collected, and a V-shaped lattice member whose downstream side is convex with respect to the flow direction of the cooling water, and a cleaning body from the downstream end of the lattice member. And an extraction tube for extracting the water.
そして、胴体の内部であって、V字状に形成された格
子部材の下流側端部近傍まで達するような整流部材を設
置したことを特徴とする。この整流部材は冷却水の整流
する効果を有するものである。Then, a rectifying member is provided inside the body, which is located near the downstream end of the V-shaped lattice member. This rectifying member has the effect of rectifying the cooling water.
格子部材に直交するように流入する冷却水の流れは、
胴体の内部に設置された整流部材に衝突する。これによ
り、洗浄体の転動を妨害するような冷却水の偏流が抑制
される。The flow of the cooling water flowing perpendicular to the lattice member is
It collides with a rectifying member installed inside the fuselage. This suppresses the drift of the cooling water that hinders the rolling of the cleaning body.
以下、本発明の一実施例を第1図により説明する。 Hereinafter, an embodiment of the present invention will be described with reference to FIG.
第1図に示される洗浄体捕集装置は、熱交換器から排
出される冷却水の流路に設置され、熱交換器の伝熱管の
内面を洗浄するために流される洗浄体を捕集するもので
ある。The washing body collecting device shown in FIG. 1 is installed in the flow path of the cooling water discharged from the heat exchanger, and collects the washing body flowing to wash the inner surface of the heat transfer tube of the heat exchanger. Things.
そして、洗浄体捕集装置は、冷却水を流す胴体1と、
冷却水を通すと共に洗浄体を集め、冷却水の流れ方向に
対して下流側が凸のV字状に形成された格子部材2と、
格子部材2の下流側端部から洗浄体を抽出する抽出管6

去された貝類等の異物を下流側に流す。And the washing | cleaning body collection device, the fuselage 1 which flows cooling water,
A lattice member 2 formed by passing the cooling water and collecting the cleaning bodies, forming a V-shape on the downstream side with respect to the flow direction of the cooling water;
Extraction tube 6 for extracting the washing body from the downstream end of lattice member 2
And The lattice member 2 operates around the rotating shaft 3 and causes foreign substances such as shellfish removed when the cleaning body cleans the inner surface of the heat transfer tube of the heat exchanger to flow downstream.
冷却水の整流効果を有する整流部材4は胴体1の内部
に形成され、V字状に形成された格子部材2の下流側端
部近傍まで達するように設置される。A rectifying member 4 having a cooling water rectifying effect is formed inside the body 1 and is installed so as to reach near the downstream end of the V-shaped lattice member 2.
第1図には図示していないが、例えば上流側に曲部を
有する配管が設置されていた場合には、冷却水の大部分
は胴体1と平行な流れとなるが、水流aのような流れも
発生する。このような水流が偏流の原因と考えられる
が、整流部材4を形成することにより整流部材に接触し
反転した水流は、整流部材4に衝突し、多くのエネルギ
ーを取られるため偏流を抑制できる。Although not shown in FIG. 1, for example, when a pipe having a curved portion is installed on the upstream side, most of the cooling water flows in parallel with the body 1, but the cooling water flows like the water stream a. Flow also occurs. Such a water flow is considered to be a cause of the drift. However, the water flow that contacts the rectifying member and is reversed by forming the rectifying member 4 collides with the rectifying member 4 and takes a lot of energy, so that the drift can be suppressed.
また、整流部材4には補強部材5が形成される。 Further, a reinforcing member 5 is formed on the rectifying member 4.
整流部材4及び補強部材5により、整流部材4及び補
強部材5に接触し反転した一部の水流は、補強部材5の
下流側に形成される渦流bにより多くのエネルギを取ら
れるため、整流部材4のみが設置される場合より、流速
が更に低下し、胴体1と平行な流れをより短かい区間で
作ることができる。Since the rectifying member 4 and the reinforcing member 5 make contact with the rectifying member 4 and the reinforcing member 5 and invert a part of the water flow, a large amount of energy is taken by the vortex b formed downstream of the reinforcing member 5. The flow velocity is further reduced as compared with the case where only 4 is installed, and a flow parallel to the fuselage 1 can be created in a shorter section.
更に、補強部材5により整流部材4が強化でき、整流
部材4を軽量化することができる。Further, the rectifying member 4 can be strengthened by the reinforcing member 5, and the rectifying member 4 can be reduced in weight.
本発明によれば、胴体の内部で冷却水の整流を行うた
め、上流側に整流板を必要としない。狭隘な配管にも設
置できるという効果がある。According to the present invention, since the cooling water is rectified inside the body, a rectifying plate is not required on the upstream side. There is an effect that it can be installed even in a narrow pipe.
