Embodiment

[0081] use figure 1 To illustrate an embodiment of the spray washing method.

[0082] figure 1 It is a process chart of the spray washing method of the embodiment of the present invention.

[0083] The spray washing method of this embodiment is characterized in that the broken pieces of solid carbon dioxide are used for the emission material, such as figure 1 As shown, the method includes: a process of generating plate-shaped solid carbon dioxide using a broken piece as a launch material (step S10), a process of transporting the generated plate-shaped solid carbon dioxide to a work site, etc. (step S20), at a work site, etc. The process of crushing the plate-shaped solid carbon dioxide (step S30), the process of throwing the crushed pieces into a cleaning device (spraying device) (step S40), and blowing them onto the object to be cleaned (step S50).

[0084] First, in step S10, liquid carbon dioxide is previously cooled in a factory or the like in a state where a pressure higher than...

Abstract

Disclosed is a blast cleaning process wherein cleaning power can be adjusted by changing hardness, shape or size of solid carbon dioxide which is used as shot. Also disclosed are a method and an apparatus for producing solid carbon dioxide to be used in the blast cleaning process. The blast cleaning process comprises a step of producing a plate-like solid carbon dioxide (7) crushed pieces of which are used as shot (step S10); a step of conveying the plate-like solid carbon dioxide (7) into a work site (step S20); a step of crushing the plate-like solid carbon dioxide (7) at the work site or the like (step S30); a step of introducing the crushed pieces into a cleaning apparatus (blast apparatus) (step S40); and a step of performing cleaning by blasting the crushed pieces onto an object to be cleaned (step S50).

Description

Technical field [0001] The present invention relates to a spray washing method using crushed pieces of solid carbon dioxide as an emitting material, and more particularly to a spray washing method capable of adjusting the cleaning ability by changing the hardness and size of the emitting material, a manufacturing method and a manufacturing device of the solid carbon dioxide used therein. Background technique [0002] Spray washing refers to a method of removing rust or paint by blowing the emitting material onto a cleaned object made of metal, ceramics, etc. at a high speed. Generally speaking, sand is mostly used for the emitting material. However, if sand is used for the emission material, the emission material is likely to remain on the object to be cleaned, and a new operation of recovering the emission material remaining on the object to be cleaned may occur. Generally, it is difficult to recycle such emission materials. In addition, as the number of processes increases, th...
