It becomes.
JP 2007-145448 A

  However, when the cleaning operation is performed as described above, the attached matter that has adhered to the object in the elevator shaft falls off and dust is generated. The generated dust floats in the elevator shaft. At this time, if the elevator door is open, the floating dust may be scattered outside the elevator shaft, that is, toward the elevator hall.

  A main object of the present invention is to provide a deposit processing apparatus and a deposit processing method capable of preventing dust generated in an elevator shaft from being scattered outside the elevator shaft. A secondary object of the present invention is to provide a deposit processing apparatus capable of guiding dust generated in an elevator shaft to a predetermined space.

  In order to achieve the above main object, the deposit processing apparatus of the present invention is an deposit processing apparatus installed in a building having an elevator shaft for guiding the lifting and lowering movement of a cage, and moves up and down in the elevator shaft. A scaffold, and a sealing member that seals an opening that communicates the space defined by the cage and the space in the building from the outside of the elevator shaft, the scaffold being the cage, and the attachment A processing apparatus is used when performing the deposit | attachment related process regarding the deposit | attachment adhering to the surface of the object in the internal space enclosed by the said elevator shaft and the said sealing member, It is characterized by the above-mentioned.

  According to the deposit processing apparatus of the present invention, since the sealing member is provided, the dust generated as a result of the deposit-related processing in the internal space is outside the elevator shaft without shielding the opening. It is possible to prevent scattering. In addition, since the opening can be shielded or opened, it is possible to smoothly perform the deposit-related process on the side of the building that defines the opening.

  In order to achieve the secondary object, the deposit processing apparatus communicates with an injection device capable of injecting granular dry ice, a lower portion of the internal space, and an external space outside the internal space. A member, an exhaust device that discharges air in the internal space to the external space through the communication member, and a gas supply device that supplies a gas containing oxygen from an upper portion of the internal space, The related process is a process in which the deposit is dropped from the surface of the object by spraying the dry ice sprayed by the spray device onto the object. Thereby, not only can the main object described above be achieved, but also the secondary object can be achieved. Specifically, since the exhaust device is provided, dust generated in the internal space can be guided toward the inside of the communicating member without being scattered outside the elevator shaft. Furthermore, carbon dioxide gas generated by using dry ice can also be exhausted from the lower part of the internal space by the exhaust device. Further, since oxygen is supplied to the internal space, an operator who performs a deposit-related process using dry ice in the internal space can secure oxygen.

  Alternatively, in order to achieve the secondary object, the deposit processing apparatus includes a communication member that communicates the internal space with an external space outside the internal space, and air in the internal space. And an exhaust device for discharging to the external space through the communication member. Thereby, not only can the main object described above be achieved, but also the secondary object can be achieved. Specifically, since the exhaust device is provided, dust generated in the internal space can be guided toward the inside of the communicating member without being scattered outside the elevator shaft.

  Moreover, it is preferable that the deposit processing apparatus as described above further includes a filter for removing dust from the air discharged by the exhaust device. Thereby, the discharged air is purified. Moreover, since the dust induced by the exhaust device is collected (recovered) by the filter, the dust is also prevented from being discharged to the external space.

  In order to achieve the above main object, the deposit processing method of the present invention includes an opening that communicates a space defined by a cage that moves up and down in an elevator shaft included in a building and a space in the building.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a longitudinal sectional view showing a schematic configuration of a building in which an asbestos removal apparatus as an attached matter processing apparatus according to an embodiment of the present invention is installed. FIG. 2 is an enlarged cross-sectional view of the door portion of the elevator installed in the building of FIG.

  A building 10 shown in FIG. 1 is a four-layered structure including a first-floor portion to a fourth-floor portion, and an elevator 50 is further installed. Each floor of the building 10 functions as an elevator hall. The floor of the first floor portion of the building 10 is at the same height as the ground surface 1.

  The elevator 50 includes a cage 51 including a housing for carrying people and things, and an elevator shaft 52 that guides the cage 51 to move up and down in the vertical direction. The cage 51 can be stopped on each floor of the building 10. The elevator shaft 52 is a structure erected in the vertical direction. A pit 53 is formed at the bottom of the space defined by the elevator shaft 52. The pit 53 is for storing the cage 51 at a position lower than the ground surface 1. In addition, a machine room 54 in which a machine for moving the cage 51 up and down is installed above the elevator shaft 52 in the building 10.

  As shown in FIG. 2, the cage 51 has an openable / closable door (door) 51a provided outside the casing. The elevator hall of the building 10 is also provided with a door (door) 10a that can be opened and closed. In the example shown in FIG. 2, the door 51a is in a closed state, and the door 10a is in an open state. During normal operation of the elevator 50, the door 10a for the elevator hall and the door 51a for the elevator 50 are opened and closed when the cage 51 is stopped on the stop floor. Form. This doorway corresponds to an opening that communicates the space in the cage defined by the cage 51 and the space in the elevator hall of the building 10.

  Moreover, the asbestos removal apparatus 100 is installed in the building 10 mentioned above. The asbestos removal apparatus 100 is used when performing asbestos removal work. In the asbestos removal work, there is a work of peeling / dropping off asbestos, which is a harmful substance attached to these objects, from the object surface (ceiling surface, wall surface 52a, etc.) in the elevator shaft 52 or the wall surface near the door 10a. Become the center. Therefore, the asbestos removal operation is an example of the deposit related process.

  As shown in FIG. 1, the asbestos removal apparatus 100 seals the scaffold 51b that moves up and down in the elevator shaft 52 and the opening for the door 10a of the elevator hall from the outside of the elevator shaft 52 (that is, on the elevator hall side). And a blast machine 150 capable of injecting granular dry ice in a compressed state.

  The sealing member 140 is installed so as to partition the elevator hall on each floor of the building 10 in the vertical direction. Here, the sealing member 140 is configured by a highly airtight sheet-like member, and is, for example, a sheet made of PET (polyethylene terephthalate). In addition, a door that can be opened and closed so that a worker can directly enter the work place in a sealing member 140 (a sealing member 140 that contacts a security zone 220 described later) installed on the first floor portion of the building 10. (Not shown) is provided.

  The asbestos removal apparatus 100 includes a duct 110 which is a hollow member, a dust collector 120 having an exhaust function and a dust collection function, and a blower 130. The duct 110 has an intake port 111 and an exhaust port 119. The intake port 111 is disposed in the elevator shaft 52. The exhaust port 119 is disposed outside the elevator shaft 52 and is connected to the dust collector 120. The air blower 130 is comprised from the air blower 131 and the piping 132 connected to it.

  As the duct 110, for example, a flexible duct or a telescopic duct can be used. The flexible duct is a hollow member surrounded by a flexible member having flexibility and airtightness. Since the flexible duct is flexible, the flexible duct can be arbitrarily bent along, for example, a corner portion in the building 10. It is also stretchable. The telescoping duct is formed so that it can be expanded and contracted stepwise in the length direction. By using such a flexible duct or a telescopic duct, it is easy to install the duct 110 in the indoor space 20 having an arbitrary size and an arbitrary shape. Furthermore, since the volume occupied by the outer shape of the duct 110 is reduced by making the flexible duct or the telescopic duct into a contracted state, it is easy to carry.

  Further, a filter (not shown) is installed in the duct 110 at a position corresponding to the air inlet 111. This filter is a filter having a coarser mesh than a later-described HEPA filter (high efficiency particle air filter) included in the dust collector 120, and functions as a prefilter that makes it difficult to cause clogging of the HEPA filter. Thereby, the exchange frequency of the HEPA filter with which the dust collector 120 is provided can be suppressed.

  When activated, the dust collector 120 exhausts in the direction of arrow A shown in FIG. 1 (exhaust function). At the time of exhaust, the dust collector 120 takes in the air in the elevator shaft 52 through the air inlet 111 of the duct 110 (see arrow B), and moves the taken air toward the air outlet 119. Thereby, in the duct 110, the exhaust path from the arrow B to the arrow A shown in FIG. The dust collector 120 has an exhaust capacity set to such a height that the work place can be set to a negative pressure in order to realize ventilation of the work place for performing asbestos removal work. The dust collector 120 includes a HEPA filter (not shown) that is fine enough to allow ventilation. When the air in the elevator shaft 52 is sucked in, the dust collector 120 also sucks in dust such as dust floating in the air, and collects the dust with the HEPA filter at the time of exhaust (dust collecting function). Thereby, the air exhausted by the exhaust function of the dust collector 120 is dedusted, and as a result, is cleaned.

Next, asbestos removal work in the elevator shaft 52 will be described.
FIG. 3 is a flowchart showing the steps of asbestos removal work in the elevator shaft 52 shown in FIG.

  In FIG. 3, first, in the first step (step S <b> 1: curing step), the workplace where the asbestos removal operation is performed is covered. Here, the term “curing” is also referred to as an isolated hermetic curing, and surrounds and surrounds the work area with a highly airtight sheet or the like, thereby making the space inside the work place a sealed space and isolating it from other spaces (outside the work place). That means.

  Curing of the workplace is completed by installing a sealing member 140, which is a part of the asbestos removal apparatus 100, in the elevator hall of the building 10 in the vicinity of the elevator shaft 52, thereby dividing the elevator hall. The installed sealing member 140 is fixed to the floor or wall surface of the elevator hall with an adhesive tape or the like.

  By installing the sealing member 140, a space surrounded by the elevator shaft 52 and the sealing member 140 is formed in the space in the building 10. This space becomes a work place for performing asbestos removal work. Therefore, the internal space in the work place is isolated from the space in the building 10. In this way, by curing the workplace, asbestos in the workplace is prevented from leaking to the outside. In the first step, the outer peripheral surface of the cage 51 is also surrounded and covered with a highly airtight sheet or the like. Thereby, the asbestos in the work place is also prevented from entering the housing of the cage 51.

  An example of the installation procedure of the sealing member 140 will be described. First, it fixes to the floor surface of an elevator hall so that the lower end of the sealing member 140 may be near the lower part of the door 10a. Subsequently, with the sealing member 140 having some clearance, the upper end of the sealing member 140 is fixed to the wall surface of the elevator hall near the door 10a. Finally, the side end portion of the sealing member 140 is fixed to the wall surface of the elevator hall. As a result, when the door 10a is opened, the wall surface of the elevator hall (for example, the surface of the three-sided frame) in the vicinity of the door 10a is exposed to the internal space of the work place, and when the door 10a is closed, the door 10a is covered. The wall surface 52a of the elevator shaft 52 that has been exposed is exposed to the internal space of the work place. In addition, by installing the sealing member 140 as shown in FIG. 2, it is possible to prevent the portion where asbestos is not attached (the floor surface, wall surface, ceiling surface, etc. of the elevator hall) from being exposed to the internal space of the workplace. can do.

  Of the sealing members 140 installed on each floor of the building 10, the sealing member 140 installed on the first floor is installed at a position away from the elevator shaft 52 by a predetermined distance, as shown in FIG. 1. Thereby, a work space can be secured in the first floor portion in the space in the work place.

  In the first step, other components of the asbestos removal apparatus 100 are also installed. In the example shown in FIG. 1, the blast machine 150 of the asbestos removal apparatus 100 is placed on the scaffold 51 b, that is, on the housing of the cage 51. The duct 110 is installed such that the air inlet 111 is disposed below the pit 53 and the air outlet 119 is disposed outside the sealing member 140 (outside the work place). The dust collector 120 is installed outside the work site, for example, on the first floor portion of the building 10 and connected to the exhaust port 119 of the duct 110. The blower 131 of the blower device 130 is installed in the machine room 54, and the pipe 132 is installed so as to penetrate the floor surface 54 a of the machine room 54.

  Subsequently, in the second step (step S2: incidental facility installation step), a security zone 220 is installed as an incidental facility of the asbestos removal apparatus 100. The security zone 220 is installed on the first floor portion of the building 10 and includes a front room and an air shower room. The front room of the security zone 220 is a work entrance for a worker to enter or leave the work place. As described above, by providing the security zone 220, it is possible to prevent leakage of asbestos to the outside due to the worker handling asbestos going out of the workplace.

  Thereafter, in the third step (step S3: negative pressure setting step), the dust collector 120 is operated, thereby exhausting the workplace and setting the atmospheric pressure in the workplace to a negative pressure lower than the atmospheric pressure. Moreover, by operating the air blower 130, air is moved to the arrow C direction shown in FIG. Thereby, fresh air (gas containing oxygen) is supplied into the work place. As a result, replacement of the air in the workplace (ventilation) is achieved, so that the worker can easily secure oxygen.

  Here, the supply amount (supply volume) per unit time of the air supplied by the blower 130 is controlled to be smaller than the exhaust amount (supply volume) per unit time of the air exhausted by the dust collector 120. Thereby, the state where the internal pressure of the work place does not become too low is maintained, and the negative pressure set in the work place is maintained. Thus, by maintaining the negative pressure of the workplace, the dust containing asbestos generated in the fourth step described later is guided to the exhaust path from arrow B to arrow A, and the induced dust is The dust is collected by the HEPA filter of the dust collector 120 or the like. Thereby, the exposure of asbestos to the exterior of a workplace can be prevented.

  In the fourth step (step S4: asbestos removal step), asbestos removal work is performed. Asbestos removal work is carried out in the order from the upper part (high place) to the lower part (low place) of the cured work place. Therefore, first, the worker gets on the housing of the cage 51 from the elevator hall on the first floor. That is, the housing of the cage 51 serves as a scaffold 51b for asbestos removal work. In other words, it can be said that the existing cage 51 forms a part of the asbestos removal apparatus 100. Then, the worker moves to the uppermost part (high place) in the elevator shaft 52 using the cage 51.

  Subsequently, in order to remove asbestos from the building 10, the worker applies an external force to the asbestos attached to the surface of the object (the ceiling surface, the wall surface 52 a, etc.) in the elevator shaft 52 and the wall surface in the vicinity of the door 10 a. Act. As a result, asbestos peels off from the surface of the object. In the present embodiment, in order to drop off asbestos, first, manual work is performed using a spatula, leather skin, brush, or the like. Subsequently, the worker performs a dry ice blasting method using the blast machine 150. In the dry ice blasting method, granular dry ice sprayed by the blast machine 150 is sprayed on an object, and asbestos adhering to the object is dropped from the object surface by collision energy generated at the time of the spraying. If there is a possibility that asbestos may remain without dropping even by these operations, an operation of making the asbestos harmless by applying a chemical to asbestos is also performed. Then, the removed asbestos is collected manually. This removes asbestos from the workplace.

  Here, the dust containing asbestos that has fallen off from the object in the elevator shaft 52 is scattered in the work place, but since the sealing member 140 is installed, the dust is not scattered to the elevator hall. Therefore, the dust is collected (recovered) by a filter provided in the intake port 111 or a HEPA filter of the dust collector 120. This also achieves removal of asbestos from the workplace.

  By the way, the dry ice (solid) used in the implementation of the dry ice blasting method becomes carbon dioxide gas as a result of sublimation (vaporization). Therefore, a large amount of carbon dioxide gas is generated in the workplace. This carbon dioxide gas is discharged out of the work place by an air flow (arrow B) generated in the work place when the dust collector makes the work place have a negative pressure. Here, since the specific gravity of carbon dioxide gas is larger than that of air, the carbon dioxide gas tends to stay in the pit 53 at the bottom of the elevator shaft 52. For this purpose, the air inlet 111 of the duct 110 is disposed below the pit 53. Thereby, it is possible to quickly exhaust the carbon dioxide gas before it stays and fills the lower part of the work place. That is, carbon dioxide gas can be efficiently excluded. As a result, it is possible to prevent the worker from being exposed to the danger of oxygen deficiency, thus ensuring the safety of the worker.

  When the asbestos removal work at the uppermost part of the elevator shaft 52 is completed, the asbestos removal work is performed at the moved position by moving downward from the uppermost part. Then, the above-described operation is repeated, and finally the asbestos removal operation at the lowermost part (pit 53) of the elevator shaft 52 is performed. In addition, the asbestos removal work in the pit 53 is performed on the bottom surface 53a of the pit 53 without using the cage 51 as the scaffold 51b. In this way, the asbestos removal work in the elevator shaft 52 is completed.

  After the fourth step is completed, the installed asbestos removal apparatus 100 and its incidental equipment are removed, or the recovered asbestos is transported to the final disposal site to complete this step.

  According to the process of FIG. 3, since the workplace is cured (sealed) using the sealing member 140 in the first step, the workplace created by curing without shielding the doorway for the elevator 50 with the door 10a. It is possible to prevent dust containing asbestos generated during the asbestos removal operation from being scattered toward the elevator hall. Further, since the work place is cured by the sealing member 140, the entrance / exit for the elevator 50 can be shielded or opened by the door 10a. Thereby, the asbestos removal operation | work with respect to the wall surface (The wall surface 52a of the elevator shaft 52, the surface of a three-way frame) etc. can be performed smoothly.

  Moreover, according to the process of FIG. 3, since the cage 51 is used as the scaffold 51b, it is not necessary to assemble a scaffold in the work place. Thereby, the time and cost required for assembling the scaffold can be reduced. Moreover, since the time required for assembling the scaffold can be reduced, the construction period for the entire asbestos removal work can be shortened, and the operation of the elevator 50 can be resumed early. That is, by shortening the construction period, the period during which the elevator 50 cannot be used is shortened.

  Further, since the dust collector 120 having an exhaust function is provided, the dust generated in the internal space of the work place is guided to the exhaust path defined by the duct 110 without being scattered toward the elevator hall. be able to. Also, carbon dioxide gas generated by using dry ice can be exhausted from the lower part of the internal space of the work place by the dust collector 120. Furthermore, since oxygen is supplied to the internal space of the work place by the blower 130, a worker who performs asbestos removal work using dry ice in the internal space of the work place can secure oxygen. By these, asbestos removal work can be performed safely and smoothly.

  Further, since the HEPA filter provided in the dust collector 120 and the filter provided at the intake port 111 of the duct 110 perform dust removal of the air discharged to the outside of the work place, the discharged air is purified. In addition, the dust guided by the dust collector 120 toward the exhaust path is collected (collected) by a filter installed in the duct 110 or a HEPA filter of the dust collector 120, so that the dust containing asbestos is discharged outside the workplace. This is also suppressed. Thereby, the safety | security around the workplace which performs asbestos removal work can be ensured reliably.

  In the above-described embodiment, the dry ice blasting method is performed during the asbestos removal operation. However, the dry ice blasting method may not be performed. In this case, since the blast machine 150 is not used, carbon dioxide gas is not generated. For this reason, it is not necessary to arrange the air inlet 111 of the duct 110 at the lower part of the work place, and the air inlet 111 is arranged at an arbitrary place in the work place. Furthermore, since carbon dioxide gas is not generated, it is not necessary to install the blower 130 for actively supplying oxygen into the work place. When the dry ice blasting method is not performed, the dust collector 120 of the asbestos removal apparatus 100 guides the dust generated in the internal space of the workplace to the exhaust path defined by the duct 110, and the induced dust. Are collected (recovered) by the HEPA filter or the duct 110 filter, and the air discharged to the outside of the workplace is purified.

  By the way, as measures against asbestos (attachment-related treatment) when the dry ice blasting method is not performed, there are containment and enclosure. Containment is a measure for preventing the falling off (scattering) of harmful substances by coating the surface of the harmful substances with the chemical liquid by spraying the chemical liquid toward the wall surface 52a or the like. Enclosure is a measure to prevent the harmful substance from falling off by surrounding the entire wall surface 52a to which the harmful substance is attached, that is, surrounding the harmful substance with another member. The containment and the enclosure may be performed as a secondary measure for asbestos that may remain after the asbestos is positively removed by manual operation or dry ice blasting.

  In the above-described embodiment, the dust collector 120 has both an exhaust function and a dust collection function, but may be an exhaust device (blower) having only an exhaust function. In this case, a HEPA filter that implements a dust collecting function is installed in the duct 110 or the like.

  Furthermore, in the above-described embodiment, the removal target is asbestos, but may be harmful substances other than asbestos (for example, dioxins or radioactive substances). Further, the object to be removed is not limited to harmful substances, and may be attached substances such as dust attached to an object in the elevator shaft 52. However, since the scattering (exposure) to the outside of the workplace tends to be a problem when the removal target is a harmful substance, the present invention is highly effective when the removal target is a harmful substance.
