There is a case where the neutralization processing passage of the neutralization device 10 is blocked by being mixed in the inside.
このため凝縮水が排水されなくなり受け皿８よりあふれ
出て主熱交換器２やバーナ１上に滴下し腐蝕や異常燃焼
等が発生するという問題点を有していた。For this reason, there is a problem that the condensed water is not drained and overflows from the tray 8 and drops on the main heat exchanger 2 and the burner 1 to cause corrosion and abnormal combustion.
本発明は上記問題点に鑑み、凝縮水の逆流を防ぎ、凝縮
水滴下による腐蝕、異常燃焼等の発生を防止するもので
ある。In view of the above problems, the present invention prevents backflow of condensed water and prevents corrosion, abnormal combustion, and the like due to dropping of condensed water.
問題点を解決するための手段 そこで上記問題点を解決する本発明の技術的な手段は、
前記受け皿と中和装置を接続する凝縮水管の一部に、前
記凝縮水管と縁切りしてホッパーを取り付けたものであ
る。Therefore, the technical means of the present invention for solving the above problems,
A hopper is attached to a part of the condensate water pipe that connects the tray and the neutralization device, and a hopper is attached to the condensate water pipe so as to cut the edge.
作 用 この技術的手段による作用は次のようになる。すなわ
ち、受け皿に回収された凝縮水は凝縮水管を通りホッパ
ーにて受けられ中和装置へ流入していく。Operation The effects of this technical means are as follows. That is, the condensed water collected in the tray is received by the hopper through the condensed water pipe and flows into the neutralization device.
中和装置の通路が閉塞された場合、凝縮水はホッパー上
面まで上昇するが凝縮水管とは縁切りされているため受
け皿へ逆流することはない。ホッパー上面よりオーバー
フローする凝縮水は下部に設けた凝縮水オーバーフロー
受け皿にて回収され機外へ排水される。When the passage of the neutralization device is closed, the condensed water rises to the upper surface of the hopper, but does not flow back to the tray because it is cut off from the condensed water pipe. Condensed water that overflows from the upper surface of the hopper is collected in the condensed water overflow tray provided in the lower part and drained out of the machine.
この結果、まんがいち中和装置の通路が閉塞されても受
け皿側への逆流がなく、凝縮水滴下による器具の腐蝕、
異常燃焼等の発生を防止することができるものである。As a result, even if the passage of the Mangaichi Neutralizer is blocked, there is no backflow to the saucer side and corrosion of the equipment due to condensed water dripping,
It is possible to prevent the occurrence of abnormal combustion.

管１４へ接続されている。In FIG. 1, the condensed water generated on the surface of the auxiliary heat exchanger 3 is recovered by the tray 8 and guided to the condensed water pipe 9.
Here, a hopper 12 is provided in the middle of the condensed water pipe 9 so as to cut off the edge of the pipe, and the condensed water is cut off along the edge of the tray 8. The condensed water received by the hopper 12 is guided to the neutralization device 10 where it is neutralized and the drain pipe 1
It is discharged from the machine from 1. A condensed water overflow tray 13 is provided below the hopper 12 and is connected to an overflow pipe 14.
