Abstract

PURPOSE:To safely further sanitarily hold a work environment by simultaneously cutting and sucking asbestos by a peeling member and a suction hood and introducing dust of the sucked asbestos to a collector via an enclosed circuit to be captured in the water. CONSTITUTION:Simultaneously cutting and sucking asbestos by a peeling member 1 and a suction hood 2, dust of the sucked asbestos is introduced to a collector 4 via an enclosed circuit 3 being captured in the water, and the secondary capture is performed in a wet cyclone 6 while showering is applied to air passing through the collector. Further the tertiary capture is performed in a scrubber 7 and a laminated layer filter 8 for the secondary capturing air. The peeling member 1 and the suction hood 2 are integrally formed, and connecting the asbestos dust to the enclosed circuit 3 and its inside to the collector 4, wet cyclone 6 and the scrubber 7, the plural layer filter 8 is provided in the final position of the enclosed circuit 3.

Description

[Detailed Description of the Invention] l) Industrial Application Field - When removing asbestos, the harmful effects of dust and waste generated during the work process on the human body are a serious social problem. This problem can be used to maintain a safe and sanitary working environment for those engaged in removal work, and to prevent air pollution during the work process and after collection.

■By excluding the cutting attachment from the overall system, it can be used for road cleaning, including collecting dust such as car powder.

2) Differences from conventional technology Traditionally, when removing asbestos, the target area (room) was sealed with a vinyl sheet and a negative pressure device was installed to prevent asbestos from scattering outside.

In addition, while spraying and dispersing water or wetting materials for wetting, the work is mainly carried out manually using scrapers, brushes, etc. This invention was designed to remove the side layer and cutting of asbestos while maintaining the conventional work environment. The aim is to perform consistent mechanical processing from collection and recovery to storage in a transport container using a *m circuit using a suction method.

3) Problems to be solved ■ With the conventional technology, there are cases in which work is unavoidable in an environment where the floating density of dust within the work site is higher than before the work. Therefore, there are serious concerns about the health management of workers.

■Furthermore, with conventional technology, there is a risk that the collected asbestos dust, etc. may be scattered around when it is stored in a transport container.

4) Means for Solving the Problems As a means for solving the above problems, the present invention includes: (1) To prevent dust from falling and scattering from the cutting attachment, a hood is attached to suck it up.

■Dust collected by suction becomes moist during the collection process, undergoes multiple collection processes using a cyclone and scrubber, is processed in a sealed circuit, and is then stored in a transport container.

5) Function - The hood absorbs dust from cutting without causing it to fall or scatter.

■The wetting device adds water to the sucked dust so that it does not scatter again before the next process.

■Cyclones collect moist dust by suction.

■The scrubber collects fine asbestos particles that cannot be collected by the cyclone ■）l EP A filter removes and finally exhausts the fine dust that cannot be collected by the scrubber.

■Directly connected pipes store the waste collected through each collection device directly into the transport container.

6) Examples In addition to the removal of asbestos building materials, the following examples are possible with this proposal.

■Application to on-site purification of demolition work in partial renovation of buildings.

■Applicable to road cleaning work by replacing the suction attachment.

■Applicable to cleaning civil engineering and architectural works by replacing suction attachments.

7) Effect ■ The floating density of dust during work is extremely lower than that of conventional technology.

■There is no dust scattering when storing in the transport container.

■Thus, hygiene and health management of workers will be improved.

■Restrictive designation of work dates and times for FI properties will be relaxed.

■It is possible to improve work efficiency.

■Therefore, a reduction in the amount of work required can be expected.
