。"Conventional Example" Conventionally, as a method of removing soot attached to a heat exchanger for exhaust heat recovery installed in the middle of an exhaust pipe or flue of an internal combustion engine or boiler, etc., using high-pressure fluid, for example, 3
As shown in Publication No. 016, there is a method of burning and removing foreign substances such as soot attached to heat transfer tubes of a heat exchanger using a mixed gas of superheated steam and air or only superheated steam, and a method that the present inventor previously proposed. As proposed in Japanese Patent Application No. 56-45867, a large amount of pressure fluid is instantaneously injected from the outside of the flue into the inside to cause a small explosion within the designed safety range, and the explosion is caused by the instantaneous expansion. There are methods to remove soot using sudden changes in the atmosphere, such as shock waves, and pressurized fluid itself.

って生じる欠点がある。In order to carry out these methods, a high-pressure fluid supply device for supplying high-pressure fluid from the outside to the inside of the flue, etc., and one or more nozzles that blow the high-pressure fluid from this device into the inside of the flue, etc. is provided. However, in these conventional examples, the nozzle is fixed to the peripheral wall of the flue, etc., and there is a drawback that soot cannot be removed sufficiently, that is, a blind spot occurs over a relatively wide range.
このような欠点を解消するために、例えば、特公昭５５

線的に変位させることにより、死角が生じる範囲を狭く
しようとするものがある。In order to eliminate such drawbacks, for example,
As shown in Japanese Patent No. 39727, there is a method that attempts to narrow the range in which a blind spot occurs by linearly displacing a nozzle in one direction.

性能が損なわれるという欠点を伴っている。In this case, the fixed part of the pressure fluid supply device fixed to the peripheral wall of the flue and the nozzle are connected to each other through a telescopic tube. This telescoping tube is equipped with a sliding tube with a high degree of sealing performance for passing pressurized fluid inside. However, since such a sliding head with high sealing performance is expensive, this conventional type has the disadvantage of being expensive. In addition, foreign matter such as soot adhering to the surface of the telescopic tube while the telescopic tube is expanded and contracted enters the space between the sliding head and the retractable tube, causing wear and impairing its sealing performance. There is.

る。"Effects of the Invention" As explained above, according to the present invention, the nozzle is supported on the underframe which is displaceably supported inside the flue etc. along the end face of the heat exchanger via the displacement guide frame. By driving this underframe with a driving means, the nozzle can be freely displaced on a plane along the end surface of the heat exchanger. Therefore, the blind spot caused by bringing the nozzle close to the end face of the heat exchanger can be covered by moving the nozzle, and as a result, the blind spot can be eliminated. In other words, it is possible to bring the nozzle close to the heat exchanger and obtain a strong soot removal effect without creating a blind spot. In addition, since the telescopic tube is inserted into the space within the coil of the flexible section provided between the nozzle and the valve device fixed to the peripheral wall of the flue, etc., it is possible to reduce the diameter of the coil of the flexible section. The flexible portion does not sag, and the coil diameter can be reduced to make it small and compact.
更に、伸縮管により可撓部の妄動を抑制でき、可撓部の
煙道内での妄動による疲労などを少なくでき、耐久性を
高めることができる。Furthermore, the elastic tube can suppress the flexible part from moving uncontrollably, reducing fatigue caused by the flexible part moving inside the flue, and increasing durability.

Also, for a flue with a circular cross section, the displacement guide frame is not limited to the flue or the like. It may be composed of a rotating frame that rotates around the center of the rotating frame and an underframe that advances or retreats in the radial direction of the flue or the like along the rotating frame. In this case, the driving means is a rotating frame that drives the rotating frame. It is composed of a drive mechanism and an underframe drive mechanism that drives the underframe independently of the rotation of the rotating frame. Furthermore, a mixture of superheated steam and air or only steam may be used as the high-pressure fluid.
