Description
The present invention relates to a humidifying type asbestos stabilization system which can be used in the dismantling and demolition of asbestos materials or in a naturally occurring asbestos workplace. More particularly, the present invention relates to an asbestos stabilization system for asbestos- Asbestos dust generated during demolition is combined with moisture in the air and falls down to the bottom. Secondly, asbestos floating in the air is filtered using an air purifier to purify asbestos more safely. The present invention relates to an asbestos stabilization system for humidifying asbestos which can be used in dismantling or demolition of asbestos materials or in a naturally occurring asbestos workplace.
In addition, the construction and development of naturally occurring asbestos-containing mining muds can be accomplished by dismantling and demolishing asbestos materials or improving the working efficiency and working environment by installing an air dome, or a humidifying type asbestos stabilization system .
When removing the interior materials of buildings constructed with asbestos materials such as conventional schools, the asbestos was scattered and floated, which made a great risk to the safety of the workers. Conventional buildings often use asbestos or asbestos-containing materials. In recent years, as buildings such as schools constructed using asbestos materials have been demolished, it is important to secure workers' safety by using asbestos materials during demolition .
Asbestos is also known as asbestos and dolomite, and it is divided into two types in mineral composition. One of them is chrysotile-based asbestos, which is called as 温 石 綿, , And the other is amphibole (amorphous) asbestos, which is weak in fiber strength but strong in chemicals. These chrysotile and hornblende asbestos are also formed in the serpentinite in the serpentinite. Asbestos is a low-cost, low-cost material that is excellent in mechanical strength, excellent in non-flammability, insulation, durability, insulation and thermal insulation. Insulating material Electric insulation material Electrolytic membrane material (electrolytic membrane material) and brake lining material are very widely used.
However, recent studies on such asbestos have shown that asbestos dust is absorbed through the respiratory system for a long period of time, resulting in asbestosis (malignant lung disease) and malignant mesothelioma of lung cancer (malignant mesothelioma of the lung).
In particular, among these kinds of asbestos, Crocidolite is the most dangerous, followed by Amosite and then Chrysotile.
Asbestos is a very fine fiber, and the thickness of a single fiber is 3 / 100,000th of a millimeter (mm), which is less than 1 / 5,000th of the number of hair and is invisible. This is inhaled during the breathing process. Among them, malignant mesothelioma is caused by gross light, that is, gingival epithelium, which is a malignant type of cancer that develops in the pleura (pleura) and the mesothelium of the peritoneum (peritoneum). Therefore, among workers who handle asbestos, many cases of asbestosis, lung cancer and malignant mesothelioma die, resulting in various problems.
Moreover, these asbestos dusts affect not only the workers directly handling the asbestos but also the workers' family and the people around them. For example, an asbestos-handling worker frequently attaches asbestos to clothes during work, and the dust is scattered in the home or in the air, thereby affecting people who are close to the worker, resulting in frequent occurrence of malignant mesothelioma . In Korea, asbestos is installed in public structures such as subways for soundproofing and insulation, and it is urgent to develop a method for removing and treating the asbestos.
Conventionally, in order to remove such asbestos, a sound pressure device is installed in the room to lower the pressure of the work space where the asbestos is to be disassembled to form a negative pressure, and the asbestos is removed using the principle of discharging air to the outside through the filter.
However, the conventional method has a disadvantage in that it takes a lot of time and money to install a sound pressure generator, and the possibility of collapsing the vinyl barrier film frequently occurs during the formation and maintenance of sound pressure.
In addition, since the concentration analysis data of the asbestos being scattered can be known at the time of completion of the disassembly work or at the end of the disassembly work, there is a problem that handwriting is difficult even if it is scattered during construction.
Disclosure of Invention Technical Problem [10] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide an asbestos- And the asbestos is trapped by the water particles so that the asbestos is lowered to the bottom without scattering, thereby stabilizing the inside of the workplace.
In addition, the asbestos floating in the air in the workplace stabilized by the high humidifier spreader is purified once again using an air purifier to prevent the asbestos from floating in the air inside the workplace, thereby allowing the operator to carry out demolition work in a clean workplace There is a purpose.
Another object of the present invention is to provide an air dome for the construction and development of naturally occurring asbestos by applying the humidifying type asbestos stabilization system of the present invention to enhance safety and efficiency.
In order to accomplish the above object, the present invention provides a method for dismantling asbestos materials and a method for dismantling asbestos materials, which are applicable to dismantling and dismantling asbestos materials, A demolition method is a method for removing asbestos from a building, comprising: a vinyl screen installed in an interior space of a work site to remove asbestos material; and a mist generating device for generating a mist to maintain a relative humidity of 80 to 96% An air purifier for circulating and supplying clean air by filtering the suspended asbestos in the air inside the demolition work site; and a sanitary equipment room connected to the outside of the demolition work site to perform cleaning and returning of the worker. In order to solve the technical problem to be solved by the present invention The.
The asbestos stabilization system which can be used in the dismantling, demolition or natural asbestos workshop of the present invention can demolish the asbestos generated in the demolition workplace inside the building made of asbestos material in the most stabilized state, Health and safety can be ensured, and the contamination of the outside air can be prevented by collecting and treating the scattered asbestos.
In other words, the asbestos scattered by the mist sprayed by using the high humidifying spreader installed in the demolition work place is trapped in the water and falls down. Secondly, the asbestos floating in the air is collected by using the air purifier, Is effectively removed.
In addition, by blocking the inside of the workplace with a plastic shielding film, it is possible to prevent the inflow of outside air, and the asbestos scattered in the workplace can be safely removed because the asbestos is not accumulated in the work space or the gap.
And if you use high humidifier spreader to spray water in the air inside the workplace, asbestos and water will be adsorbed and the heavy asbestos will go down and it will be easy to remove asbestos, and high technology like maintenance of sound pressure is needed And it is effective to shorten the equipment and work time required for the work, thereby reducing the work cost.
Further, the method can be easily applied to various environments, and is more versatile than the conventional asbestos removal method.
