Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cleaning a papermaking and corrugated board factory and a factory in a similar situation.

[0002]

2. Description of the Related Art Conventionally, in paper manufacturing, corrugated board factories, etc., a large amount of paper powder and combustible fine powder are generated due to the manufacturing and processing of paperboard and corrugated board, and they are deposited and adhered to various parts in the factory along with dust, dust, etc. The cleaning around the machine is about the amount that an operator blows away paper dust and combustible fine powder with an air gun.
When they are deposited on the ceiling beams, floors, window bars, ventilation ducts, etc., the paper dust and combustible fine powder, etc. accumulated on the floor and within the reach of workers are sometimes blown by the worker. Etc., but paper dust and combustible fine powder accumulated on other parts, such as the ceiling beam, the back and back of the machine, the ventilation fan, each part of the duct, every corner, etc. accumulated and adhered. Since they contain oil, they cause a big fire, and there are problems such as air pollution in the factory and adverse effects on the health of workers.

[0003]

In particular, in a recent report, in the case of a fire accident at a papermaking or corrugated board factory, oil is impregnated into paper powder and combustible fine powder adhering to ceiling beams, around machines, ducts, etc. It is said that sparks flew to these and burned at once in the shape of a squib, causing a large fire.

The object of the present invention is to make a paper and cardboard factory which can completely clean and remove paper powder and combustible fine powder without adversely affecting various mechanical and electrical equipments in the factory, and a similar situation. The purpose is to provide a cleaning method for factories.

[0005]

In order to achieve the above object, the present invention covers the top and side surfaces of mechanical equipment and electrical equipment in a factory with vinyl sheets, and applies them to floor surfaces such as passages in a factory. Lays a vinyl sheet, raises the surrounding area upwards and installs it in a gutter shape, constructs a work scaffold, and lays vinyl in a curtain shape on the part other than the object to be cleaned. The hem part of the stretched vinyl sheet and the hem part of the vinyl sheet covering each of the above facilities are placed on top of the rising part of the vinyl sheet laid on the floor of the passage, etc., and in this state the ceiling, steel frame , Crosspieces, ducts, ventilation fans, mechanical equipment surroundings, electrical equipment surroundings, pipes, wiring, and other objects to be cleaned, from the top, in order from above. Only high-pressure air mixed with water or a suitable detergent. Jett Inside the vinyl sheet laid like a gutter on the floor surface of the passage, etc., by spraying atomized water to make the paper powder and combustible fine powder wet, and washing and removing the accumulated deposits of paper powder and combustible fine powder etc. It has been adapted to be collected in.

[0006]

[Function] Cleaning is performed on holidays at paper manufacturing factories and cardboard factories. With only high-pressure air, blown away paper dust and combustible fine powder float up in the air and float, and these are again cleaned. Although it will be deposited and adhered, high-pressure jet atomized water, which is a mixture of only high-pressure air or water mixed with an appropriate detergent in an atomized form, is sprayed onto the paper powder and flammable fine powder to absorb water. By cleaning and removing the accumulated deposits such as the paper powder and the combustible fine powder, the paper powder and the combustible fine powder can be cleaned and removed in a relatively short time without floating in the air. Also, if only high pressure water is used, the inside of the factory will be flooded, but by using high pressure jet atomized water in which only high pressure air or water mixed with an appropriate detergent is mixed in an atomized form, The quantity is relatively small,
The inside of the factory is never submerged. Then, accumulated deposits such as paper powder and combustible fine powder can be forcibly peeled off from the adhered portion by high pressure jet atomized water and washed away. Moreover, the washed paper dust and combustible fine powder flow down along the vinyl sheet covering each facility, and are collected in the vinyl sheet laid like a gutter on the floor surface of the passageway in the factory, It can be easily disposed of with a vacuum car. Furthermore, by sequentially performing cleaning from the top, paper dust, combustible fine powder, and the like do not adhere to the cleaned portion again, and cleaning can be performed efficiently. Further, since the mechanical equipment and electric equipment in the factory are covered with the vinyl sheet, there is no flooding of the high-pressure jet atomized water, and the washed-out paper powder and combustible fine powder do not fall. After cleaning, remove the vinyl sheet covering each facility, inspect each part, paint, repair, replace, etc. as necessary, remove the vinyl sheet on the work scaffolding and floor surface, and finish the cleaning.
