A gasket 35 is sandwiched between a flange mounting plate B1 mounted on a pipe B for transporting air from a compressed air generation source to a cleaning device, and fixed with bolts and nuts. This completes the installation of the cleaning device.

The operation is described below. As shown in FIG. 8, a compressed air source C generates compressed air of 7 to 10 kgf / cm ² , and the compressed air is controlled by an air control unit D to control the amount and pressure of air. The air is supplied from the pipe B to the flange portion F of the cleaning device at an air pressure of 5 to 8 kgf / cm ² . The high-pressure air passes through the pipe 10 of the nozzle portion N connected to the plunge portion F, and flows from the pores 12 of the baffle plate 11 provided at the tip of the pipe 10 to the inner wall of the cleaning object A at an air pressure of 5 to 8 kgf / cm ^2. A strong spray is applied to the attached matter E.

As shown in FIG. 10, high-pressure air ejected from the fine holes 12 is blown onto the adherent wall surface or the peeling object protection plate 15 provided in close proximity to the baffle plate 11, and is repeatedly reflected on the inner wall surface of the cleaning object A. Further, since the surface of the deposit E attached to the inner wall adheres in a rough state, the jetted high-pressure air causes a turbulent flow near the wall and the surface of the deposit, and the deposit E is completely separated from the inner wall to be cleaned. The inner wall of the object A is to be cleanly cleaned. Thereafter, foreign matters such as conveyed articles, dust, and mist that have been separated from the inner wall are suctioned and discharged from the object to be cleaned A by the suction / extraction device G connected to the object to be cleaned A, and cleaning is completed. If the cleaning device is stopped for some reason,
Since the exfoliated material may enter the pores 12 of the baffle plate 11, the exfoliated material can be prevented from entering by the exfoliated material protection plate 15. Of course, the separation object protection plate 15 has an effect of causing turbulence in the article A to be cleaned, which becomes an obstacle to the ejection of the high-pressure air. Further, since the pressure seal plate is provided in the gap between the nozzle portion N and the mounting outer cylinder portion O, the high pressure in the cleaning target A is sealed by the labyrinth effect. The labyrinth effect can be further enhanced by appropriately increasing the number of pressure seal plates.

[0024]

Since the present invention has the above-described structure, it has the following effects.

The nozzle is composed of a nozzle, a mounting outer cylinder covering the nozzle, and a flange. Since each has a simple structure, there are few troubles, breakage, etc., and much maintenance is not required. If a problem occurs, it can be easily replaced, and the cleaning device itself is compact and easy to transport.

The insertion amount of the pipe of the nozzle portion, that is, the insertion length in the object to be cleaned depends on the amount and location of the object adhered to the inner wall of the object to be cleaned and the shape and size of the object to be cleaned. It can be easily adjusted by the length of the outer cylinder of the outer cylinder or by a pipe provided with a baffle plate at the nozzle.

If the nozzle portion and the flange portion, or the nozzle portion and the mounting outer cylinder portion and the flange portion are integrally formed, the time required for mounting the nozzle portion and the mounting outer cylinder portion on the flange portion can be reduced.

In the narrow hole of the baffle plate provided at the tip of the pipe of the nozzle portion, the diameter of the passage through which high-pressure air flows from the inlet side, that is, the pipe side, is reduced, and the outlet side, that is, the high-pressure air The outlet has a large diameter and a spiral groove is provided on the inner wall of the high-pressure air passage, so that it can be sprayed over a wide area on the inner wall with attached matter, and turbulent air flows near the inner wall and the attached matter surface In addition, since the deposits can be completely peeled off from the inner wall, no cleaning residue is caused.

The fixing surface of the flange provided on the outer cylinder for fixing the mounting outer cylinder portion to the object to be cleaned is flat or curved, so that it can be in close contact regardless of the shape and size of the object to be cleaned, without causing air leakage. It can correspond to various shapes of the cleaning object.

Since the separated material protection plate is provided close to the pores of the baffle plate, the high-pressure air ejected from the fine holes causes turbulence in the object to be cleaned by the separated material protection plate serving as an obstacle, and the adhered material is removed. In order to create a situation in which the surface is easily peeled off from the inner wall surface, the attached matter is completely peeled off, and the inner wall of the object to be cleaned is cleaned cleanly. In addition, when the cleaning device is stopped halfway, the peeled-off material protection plate may cause the peeled-off material that has already been peeled into the pores of the baffle plate, which can be prevented.

Since a plurality of pressure seal plates having different diameters are alternately provided in the pipe of the nozzle portion so as to be located in the gap between the nozzle portion and the mounting outer cylinder portion, the high pressure in the object to be cleaned is reduced by the labyrinth effect. Can be sealed. For this reason, the gap between the nozzle portion and the mounting outer cylinder portion does not become high pressure, and the pressure resistance of the flange portion can be reduced. In addition, when the inside of the object to be cleaned such as an incinerator has a high temperature, the pressure seal plate has an effect of preventing high heat from being transmitted to the cleaning device and its peripheral devices.
