Description

  The present invention relates to a crematory furnace and a cremation method.

  The cremation furnace burns fuel gas (including LP gas, city gas, kerosene and heavy oil, the same shall apply hereinafter) as a heat source to perform cremation. For this reason, the cremation furnace is required to shorten the cremation time from the viewpoint of reduction of running cost and improvement of operation efficiency.

  In order to shorten the cremation time, Patent Document 1 describes a cremation furnace capable of emitting far infrared rays from the furnace inner surface side. The cremation furnace described in Patent Document 1 promotes the drying of the body by providing an inner layer of fine ceramics that emits far-infrared radiation on the furnace inner surface side and adding far-infrared radiation heat to the combustion heat. .

Japanese Patent Application Laid-Open No. 08-094 030

  The bodies to be cremated do not require a uniform amount of heat in the direction of height for cremation. That is, although a large amount of heat is required from the head to the abdomen of the body, the leg does not require a large amount of heat as compared to this. However, although the conventional cremation furnace is provided with fine ceramics on the ceiling surface and both sides of the cremation furnace and can emit infrared rays, the heat source is due to the combustion of the fuel gas, so the heat quantity at each part in the furnace Was almost uniform. In the conventional cremator in which the amount of heat of each part in the furnace is uniform, when cremation (combustion) of the legs is finished, the burning from the head to the abdomen is insufficient, and from this time on, the head to the abdomen During the end of the combustion, the heating (heat amount) to the site of the leg becomes an unnecessary amount of heat. Since an unnecessary amount of heat is added to the part of the leg, the conventional cremator takes time to cool the cremator, and as a result, it is difficult to crem in a short time, and the operation efficiency of the cremator is increased. There was a problem that it was difficult to raise.

  In addition, the remains of the remains of the body after cremation are boned and stored in the bones. And, depending on the condition of the ashes, the personality of the deceased person is resurrected, and in particular, if the throat (the second cervical spine) and the phlegm (the first cervical spine) remain undamaged, it is because the deceased's life was good It is prized to be However, in the conventional cremator, although the fine ceramic radiates the heat transferred by the combustion of the fuel gas as far infrared rays, the heat source itself is the combustion of a large amount of fuel gas. Burning with a large amount of fuel gas causes intense convection in the cremation furnace, and the intense convection causes the ashes of the body to be damaged. For this reason, the conventional crematory furnace had the subject that it was difficult to suppress damaging an ashes.

  The present invention is intended to solve these problems, and it is an object of the present invention to provide a cremation furnace capable of improving the operation efficiency of the cremation furnace while suppressing damaging the ashes.

  A cremation furnace according to the present invention is a cremation furnace having a main burner in a main combustion chamber, and is characterized in that a ceramic heater is provided on the side where the head of the body of the main combustion chamber is disposed.

  According to the cremation furnace of the present invention, since the ceramic heater is provided on the side of the main combustion chamber on which the head of the body is disposed, the amount of heat can be increased toward the head side of the body. For this reason, the heat quantity on the leg side can be relatively suppressed, and the unnecessary heat quantity can be suppressed, so that the cooling time of the cremation furnace can be shortened. As a result, it is possible to cremate in a short time, and it is possible to improve the operation efficiency of the cremation furnace. Further, since the ceramic heater heats the body by emitting far infrared rays, unlike the combustion by the fuel gas, the strong convection does not occur in the cremation furnace. For this reason, damage to the remains of the body can be suppressed.

  Here, the upper portion of the main combustion chamber has an arch-shaped inner wall extending in the short direction, has a smoke outlet at one end in the longitudinal direction, and has the ceramic heater at the other end in the longitudinal direction. It can be

  According to this, since the ceramic heater is provided on the arch-shaped inner wall of the upper part of the main combustion chamber, the ceramic heater emits the infrared radiation in the central axis direction of the main combustion chamber (from the head of the body to the abdomen Can be concentrated in the axial direction). For this reason, the cremation in a short time is attained, and the improvement of the operation efficiency of a cremation furnace can be aimed at more.

In the upper part of the main combustion chamber, a plurality of ceramic heaters are arranged side by side in the short direction of the inner wall to form a group of ceramic heaters, and from the other end side in the longitudinal direction A plurality of groups of the ceramic heater groups are arranged side by side toward one end side,
A heating control means can be provided for each ceramic heater group.

  According to this, since the heating control means is provided for each ceramic heater group, it is possible to move the heating portion by the ceramic heater group arranged in the back and forth direction back and forth according to the height of the deceased person who is a dead body. . As a result, since heating can be performed by the ceramic heater only at a region from the head to the abdomen requiring heat, unnecessary heating can be suppressed, and thus the cooling time of the crematorium can be further shortened.

  Further, the ceramic heater may be disposed so as to protrude from the inner wall.

  According to this, since the ceramic heater is disposed to be protruded, the surface area of the main combustion chamber including the ceramic heater is increased. For this reason, the cooling time at the time of cooling of a cremation furnace can be shortened more.

  Further, the ceramic heater may be a gas-bank ceramic heater, and the main combustion chamber may be provided with a cooling mechanism for feeding air to the main combustion chamber.

  According to this, by the cooling mechanism, air is fed into the main combustion chamber to be ventilated and cooled, and the temperature of the main combustion chamber can be temporarily lowered. This makes it easy to ignite the Schwann burner, as it is difficult to ignite at high temperatures.

  Further, the cremation method according to the present invention comprises a first cremation treatment by burning a fuel gas of a main burner, and a second cremation treatment by radiation of far infrared rays of a ceramic heater performed after the first cremation treatment. It can be done.

  According to this, most of the flesh pieces of the corpse are burned by the first cremation treatment that causes intense convection in the cremation furnace, and then the second cremation treatment burns away the meat fragments and the bone (the ashes) is exposed. However, since the second cremation process does not cause intense convection, damage to the ashes can be suppressed.

  Further, the ceramic heater may be a schbankn gas ceramic heater, and a ventilation cooling process may be performed by a cooling mechanism between the first cremation process and the second cremation process.

  According to this, ventilation cooling by the cooling mechanism can facilitate ignition of the Schbank burner.

The left and right sides face the front of the cremator, with the left side as the left and the right side as the right.

  As shown in FIG. 1, the cremation furnace of the embodiment is provided with a main combustion chamber 2 for cremating (burning) a body on the lower rear side of the cremation furnace, and is generated during cremation on the upper side of the main combustion chamber 2. In the front of the main combustion chamber 2, a front chamber 4 for taking in and out the carriage 1 on which the crucible 1a is placed is provided.

  The main combustion chamber 2 is made of a refractory material and its casing is configured, and as shown in FIG. 1, the front side is open, and the opening face is provided with a fireproof door 25 for opening and closing the main combustion chamber 2. A main burner 21 for burning the gas is provided. From the fireproof door 25, the trolley | bogie 1 with which the crucible 1a was carried in and out.

  As shown in FIG. 2, the main combustion chamber 2 has a lower wall 2a on which the truck 1 is placed, left and right walls 2b and 2c extending vertically from the lower wall 2a, and right and left walls when viewed from the cross section in the left and right vertical direction. And an arch-shaped inner wall 2d extending from the upper side of 2b and 2c to the left and right (in the short direction at the top of the main combustion chamber 2). In the main combustion chamber 2, nine ceramic heaters are provided in the upper lateral direction of the main combustion chamber 2 from the left and right walls 2b and 2c on the upper side from the vicinity of the position P where the crucible 1a is fixed to the arched inner wall 2d. 22 are arranged side by side, and a group of ceramic heater groups 23 are formed. As shown in FIG. 3, four ceramic heater groups 23 are arranged side by side from the rear to the front of the main combustion chamber 2 (from the other end side in the longitudinal direction to the one end side). Further, a smoke exhaust port 24 for exhausting smoke generated when the body is cremated (burned) is provided in front of the upper portion of the main combustion chamber 2 (one end side in the longitudinal direction).

  The fireproof door 25 is formed of a fireproof material, and as shown in FIG. 1, is formed in the front opening surface of the main combustion chamber 2 in a size and shape that can seal the opening surface. The fireproof door 25 opens and closes the main combustion chamber 2, and when the carriage 1 carrying the crucible 1a is carried from the front chamber 4 to the main combustion chamber 2, and after cremation, ashes etc. (the cremation residue of the crucible 1a) When the truck 1 carrying the is carried out from the main combustion chamber 2 to the anteroom 4, it is a door which becomes an entrance and exit. The fireproof door 25 opens and closes the opening surface by moving up and down along the guides 25a arranged in parallel on the side of the opening surface.

  The main burner 21 is provided on the rear wall of the main combustion chamber 2 to burn the fuel gas to generate a flame and spread the flame over the entire main combustion chamber 2. The main burner 21 causes the flame to cremate (burn) the crucible 1a (body) and supplies the combustion energy of the main combustion chamber 2 in the first half of the cremation. Although not shown, the main burners 21 may be provided with a plurality of main burners 21 such as being provided opposite to the left and right walls 2b and 2c of the main combustion chamber 2, respectively.

  The ceramic heater 22 is a heating device using ceramics as a heating element, and heats the ceramic to radiate far-infrared rays, thereby heating the body. The main burner 21 differs from the main burner 21 in that it is heating by far-infrared radiation, not by flame combustion. The ceramic heater 22 includes a gas ceramic heater (Schbankn burner) and a ceramic electric heater depending on the energy used. Although the Schbank burner has the advantage that energy sharing can be achieved because it uses the same fuel gas as the main burner 21, it is difficult to ignite at high temperatures, so the temperature of the main combustion chamber 2 is temporarily set to ignite There is a disadvantage that it needs to be lowered. On the other hand, although the ceramic electric heater has an advantage that it is not necessary to lower the temperature of the main combustion chamber 2 because the heating start under high temperature is easy, there is a disadvantage that energy sharing with the main burner 21 can not be achieved. is there. In the embodiment, a Shuvan burner is used as the ceramic heater 22 and a cooling mechanism 6 and a discharge mechanism 7 described later are provided in the main combustion chamber 2 in order to temporarily lower the temperature of the main combustion chamber 2.

  As shown in FIG. 2, the ceramic heater 22 has a short side direction of the arch-shaped inner wall 2d of the upper portion of the main combustion chamber 2 from the left wall 2b to the right wall 2c above the vicinity of the position P where the crucible 1a is placed. The nine ceramic heaters 22 arranged side by side and arranged side by side form a group of ceramic heater groups 23. Then, four ceramic heater groups 23 are arranged side by side from the rear to the front of the main combustion chamber 2 (from the other end side in the longitudinal direction to the one end side) (FIG. 3). Since the ceramic heater group 23 includes heating control means for each ceramic heater group 23, it is possible to move the heating site by the ceramic heater 22 in the front-rear direction according to the height of the deceased person who is a dead body. ing. The heating control means is provided for each ceramic heater group 23, and can control on / off and control the heating amount for each ceramic heater group 23. As another embodiment, as shown in FIG. 4, two ceramic heater groups 23 are arranged side by side on the inner wall 2d of the upper part of the main combustion chamber 2 corresponding to the chest from the head of the dead body. It can also be done. According to this, it is possible to heat the chest accurately from the head of the body, and to suppress the damage of the prized throat (the second cervical spine) and the spine (the first cervical spine).

  As shown in FIG. 2, the ceramic heater 22 is disposed so as to protrude in the central axis direction of the main combustion chamber 2 from the inner wall 2 d of the main combustion chamber 2. Since the surface area of the main combustion chamber 2 is increased by arranging the ceramic heater 22 so as to protrude from the inner wall 2 d, the cooling time for cooling the cremation furnace can be further shortened.

  Gas or electricity, which is an energy source of the ceramic heater 22, is supplied to the ceramic heater 22 through piping passing through a support shaft 22a that supports the ceramic heater 22 in a protruding state. Piping (not shown) is made of tungsten alloy, heat resistant steel (SUH) or the like, and penetrates the housing of the main combustion chamber 2 from the gas supply port or electricity supply port as an energy supply source to the ceramic heater 22 Connected with

  The piping is disposed in the main combustion chamber 2 so as to penetrate the housing of the main combustion chamber 2 from a through hole (not shown) at one point of the housing of the main combustion chamber 2, and the inner wall 2 d of the main combustion chamber 2 To supply gas or electricity to all the ceramic heaters 22. According to this, the existing cremator can be easily remodeled into the cremator of the embodiment. That is, a through hole is provided at one place of the main combustion chamber 2 of the existing crematory furnace, and piping and a ceramic heater 22 are provided on the inner wall 2 d of the main combustion chamber 2 in the embodiment. It can be converted to a crematory furnace.

  As shown in FIG. 3, a smoke exhaust port 24 for exhausting soot generated when cremating (burning) the body is provided on the front of the upper portion of the main combustion chamber 2 (one end side in the longitudinal direction). As shown in FIG. 1, the smoke outlet 24 is connected to the smoke inlet 33 of the reburning chamber 3 via the flue 29.

  As shown in FIG. 2, the main combustion chamber 2 is provided with a cooling mechanism 6 that temporarily lowers the temperature in the main combustion chamber 2. The cooling mechanism 6 sends air from the introduction pipe 66 to the main combustion chamber 2 by an air compressor 65 to ventilate and cool the inside of the main combustion chamber 2. The air compressor 65 is provided with an air tank 65 a of 15% by volume with respect to the volume of the main combustion chamber 2. The volume of the air tank 65 a is preferably 5 to 30% by volume with respect to the volume of the main combustion chamber 2. This is because a large amount of air can be instantaneously fed into the main combustion chamber 2. When the capacity of the air tank 65a is less than 5% by volume, the ventilation cooling of the main combustion chamber 2 may be insufficient due to the capacity shortage. On the other hand, if it exceeds 30% by volume, the capacity is excessive, and the air in the air tank 65a may not be used and may be wasted. More preferably, the volume of the air tank 65 a is 10 to 20% by volume with respect to the volume of the main combustion chamber 2. Note that, instead of the air compressor 65, a blower such as an axial flow blower can also be used for the cooling mechanism 6. As the inside of the main combustion chamber 2 is ventilated and cooled by the cooling mechanism 6, the temperature of the main combustion chamber 2 is temporarily lowered. This can facilitate ignition of the Schbank burner.

  Further, as shown in FIG. 2, a discharge mechanism 7 is provided in the main combustion chamber 2. The exhaust mechanism 7 penetrates the side wall from the inside of the main combustion chamber 2 and an air compressor 71 for compressing air, an air tank 71a of an air reservoir, a conduit 72 connected from the air tank 71a to an upper exhaust duct 5 (not shown) A side pipe 73 connected to the conduit 72, and an aspirator 70 at the connection point of the side pipe 73 to the conduit 72, for sucking the gas on the side pipe 73 side by the flow of the conduit 72. By flowing compressed air from the air tank 71a to the conduit 72, the gas in the main combustion chamber 2 can be discharged, and the ventilation cooling in the main combustion chamber 2 can be promoted. In addition, as the discharge mechanism 7, instead of the air compressor 71, a blower such as an axial flow blower can also be used.

  The re-combustion chamber 3 is a furnace for burning soot generated in the main combustion chamber 2 again, and its casing is made of a refractory material. As shown in FIG. 1, smoke from the main combustion chamber 2 is located on the rear lower side. And a smoke outlet 34 for exhausting smoke re-burned in the re-combustion chamber 3 on the upper front side. The re-combustion chamber 3 is provided with a secondary burner 31 for burning soot on the rear side wall, and a catalyst 32 for promoting the burning of soot in the center in the front-rear direction. The soot is reburned by the secondary burner 31, the combustion is promoted by the catalyst 32, and the harmful substances contained in the soot are decomposed and detoxified.

  The anteroom 4 is a section provided on the front side of the fireproof door 25 of the main combustion chamber 2 at high temperature, and isolates the bereaved etc. from the high temperature main combustion chamber 2, It is a section where the heat of (the crematorium residue of 棺 1a) can be released to the outside. The weirs 1a loaded on the carriage 1 are carried to the anteroom 4 by the bereaved family, carried from the anteroom 4 to the main combustion chamber 2 by a belt conveyer not shown, and after cremating, from the main combustion chamber 2 to the antechamber by a belt conveyer It is carried out to 4. The anteroom 4 is equipped with the exhaust hood 41 which exhausts the heat | fever of the trolley | bogie 1 after cremation, and an ashes etc. (the cremation residue of the cage | basket 1a) on the upper side, and equips the front with the makeup door 45.

  Next, the usage method of the cremation furnace of embodiment, an effect | action, and an effect are demonstrated based on drawing. The cremation by the cremation furnace of the embodiment is performed by the procedure of carrying in the crucible 1a, the first cremation processing, the ventilation cooling by the cooling mechanism 6, the second cremation processing, the cooling of the cremation furnace, the unloading of ashes and the like.

  As for the delivery of the bag 1a, the bag 1a is placed on the carriage 1 and carried into the anteroom 4 by the bereaved etc., and the bereaved classifies the deceased person (the body). After the door 45 is closed and a signal for starting cremation is sent, the crucible 1a placed on the carriage 1 is carried into the main combustion chamber 2 by remote control, and the fireproof door 25 is closed.

  In the first cremation process, the crucible 1a is cremated (burned) by a flame resulting from the combustion of the fuel gas of the main burner 21. In the first cremation process, most of the meat pieces are burnt until the bones (ashes) are exposed. In addition, since the state of combustion of a piece of meat differs depending on the body type and height of the deceased person who is a dead body, the state of combustion is checked at any time from a confirmation window not shown. Since the flame resulting from the combustion of the fuel gas causes strong convection, if the first cremation process is continued after the bone is exposed, convection may damage the ashes. In addition, 800-1000 degreeC of the cremation temperature (temperature of the main combustion chamber 2) of a 1st cremation process is preferable. This is because generation of harmful substances such as dioxin and nitrogen oxide can be suppressed. If the cremation temperature is less than 800 ° C., the amount of dioxin generated may be increased. On the other hand, when the temperature exceeds 1000 ° C., the amount of nitrogen oxides generated may be increased. Moreover, in order to raise temperature rising efficiency, it is preferable to preheat the main combustion chamber 2 and the re-combustion chamber 3 before cremation.

  During the cremation process (during the first cremation process to the second cremation process), the reburning chamber 3 reburns the smoke generated in the main combustion chamber 2 by the flame due to the combustion of the fuel gas of the sub burner 31. . The smoke is reburned by the secondary burner 31 and the combustion is promoted by the catalyst 32, whereby the harmful substances contained in the smoke are decomposed and detoxified.

  Ventilation cooling by the cooling mechanism 6 is performed after the first cremation process and before the second cremation process, and by performing the ventilation cooling of the cooling mechanism 6 and discharging the discharge mechanism 7 to the main combustion chamber 2, The temperature can be temporarily lowered. The Schbankn burner (ceramics heater 22) used in the first cremation process is difficult to ignite at high temperature, so the ventilation of the cooling mechanism 6 and the discharge of the discharge mechanism 7 facilitate the ignition of the Shubank burner. Can.

  The second cremation process heats the body by the radiation of far infrared radiation from the Schwann burner (ceramics heater 22). The body is burnt by being heated, and all the pieces of meat left by the first cremation process are burnt, leaving only the bone (ashes). The second cremation treatment is different from the first cremation treatment using combustion by flame, it is heating by far infrared radiation and does not generate intense convection, so it is less likely to damage the ashes, and the condition of the ashes is improved. Can. The cremation temperature of the second cremation treatment is preferably 800 to 1000 ° C. similarly to the first cremation treatment.

  The ceramic heaters 22 are arranged side by side in the short direction of the inner wall 2 d of the upper portion of the main combustion chamber 2 to form a group of ceramic heater groups 23 and extend from the rear to the front of the main combustion chamber 2 (long Four ceramic heater groups 23 are arranged side by side (from the other end side toward the one end side) (FIG. 3). The four ceramic heater groups 23 are provided with heating control means for each ceramic heater group 23, and are heated by the ceramic heaters 22 in the front-rear direction so as to heat from the head to the abdomen of the dead depending on the height of the dead who is the dead. Move the site. As a result, unnecessary heating can be suppressed, and the cooling time for cooling the cremation furnace can be shortened.

  Cooling of the cremation furnace is performed by blowing or the like. At this time, since the heating site by the ceramic heater 22 is limited from the head to the abdomen of the body, unnecessary heat is suppressed, and the cooling time can be shortened.

  Removal of ashes etc. is performed after the dolly 1 in the cremation furnace and the ashes (such as the cremation residue of the pot 1a) are cooled to a temperature (about 300.degree. C. or less) which can be removed from the main combustion chamber 2. Etc. are carried out to the anteroom 4. After being further cooled (about 100 ° C. or less) in the anteroom 4, the carriage 1 and the ashes etc. are carried out of the cremation furnace from the dressing door 45 of the antechamber 4 and the bones are collected by the bereaved. As it happens, since the ashes are heated by far infrared radiation, they are less damaged and in good condition.

  The cremation furnace from which the ashes etc. have been carried out can continue to be used for the cremation of the next body. In addition, since the temperature in the cremation furnace is high, it is possible to omit preheating for raising the temperature raising efficiency.

  The following is a description of a body storage bag and a body storage method suitable for efficient operation of a cremation furnace when a large-scale natural disaster occurs.

  Funeral homes in the metropolitan area (crematory furnaces) that are saturated in processing capacity may be forced to wait for about seven days during normal times, until the deceased is cremated after death. In order to improve processing capacity, the cremation furnace which can radiate far infrared rays from the furnace inner surface side is described in patent documents 1 (Unexamined-Japanese-Patent No. 08-094030). The cremation furnace described in Patent Document 1 promotes the drying of the body by providing an inner layer of fine ceramics that emits far-infrared radiation on the furnace inner surface side and adding far-infrared radiation heat to the combustion heat. .

  In the past, large-scale natural disasters have often occurred, in which many people die from disaster death, and the number of bodies that must be cremated inevitably increases. However, in the conventional cremation furnace, depending on the number of remains that must be treated, it will exceed the processing capacity of the cremation furnace, and it is assumed that it will take a considerable number of days from the death of the deceased to the cremation Ru. In addition, in the case of a large-scale natural disaster, many unidentified bodies and parts of bodies also occur, and these require more days before being cremated, making it difficult to keep the bodies etc. There was a problem that

  The body storage bag and the body storage method solve these problems, and the object is to be able to facilitate storage of bodies and the like.

  The body storage bag is a body storage bag provided with an opening / closing means capable of sealing the bag opening, which is made of a synthetic resin, and the Tg (glass transition temperature) of the synthetic resin is 0 to 150 ° C. It is characterized by

  According to the body storage bag, the scratch resistance of the synthetic resin is excellent, the body storage bag is not easily damaged, and can be stored without damaging the body.

  Here, the synthetic resin may be PVC (polyvinyl chloride) resin, PET (polyethylene terephthalate) resin, or PBT (polybutylene terephthalate) resin.

  According to this, the scratch resistance of the synthetic resin is more excellent, the body storage bag is less likely to be damaged, and can be stored without damaging the body.

  Here, the body storage bag may be provided with a check valve for preventing the body storage bag from being ruptured.

  According to this, it is possible to prevent the burst due to the gas generated in the body storage bag.

  The body preservation method includes a first cooling process for injecting liquid nitrogen into a body storage bag containing a body, and a second cooling process for cooling the body storage bag under a −60 to −20 ° C. environment; It is characterized by consisting of.

  According to the body preservation method, since the body is rapidly cooled by liquid nitrogen, it can pass through the freezing temperature zone (-5 to 0 ° C.) of moisture contained in the body in a short time. For this reason, it is possible to freeze the dead without destroying the cells of the dead, and it is possible to prevent the deterioration of the dead.

  Hereinafter, an embodiment of the body storage bag will be described. The body storage bag 100 of the embodiment is a body storage bag 100 including an opening / closing means 103 capable of sealing the bag opening 101, and is formed of a synthetic resin, and the check valve 105 for preventing the body storage bag 100 from bursting. Is equipped.

  The synthetic resin that forms the body storage bag 100 preferably has a Tg (glass transition temperature) of 0 to 150 ° C. It is because it is excellent in abrasion resistance at the time of storage of a body, it is hard to damage the body storage bag 100, and it can be stored without damaging a body. If the synthetic resin has a Tg of less than 0 ° C., the synthetic resin may be in a rubber state depending on a temporary change in temperature during storage, and the scratch resistance of the synthetic resin may be deteriorated. On the other hand, when the Tg exceeds 150 ° C., the flexibility of the synthetic resin is inferior, and the workability at the time of containing the body may be inferior. More preferably, Tg of the synthetic resin is 30 to 120 ° C, and further preferably 50 to 90 ° C. Specific synthetic resins having a Tg in this range include PVC resin (polyvinyl chloride resin (Tg: 87 ° C.)), PET resin (polyethylene terephthalate resin (Tg: 69 ° C.)), PBT resin (polybutylene terephthalate resin (polybutylene terephthalate resin) Tg: 50 ° C.)). In the body storage bag 100 of the embodiment, a cylindrical PVC resin matched to the height and physique of the deceased person is used, and one of the two openings of the cylinder is used as the bag opening 101 serving as a receptacle for the body, and the other is It is sealed in a sealed, bag-like form.

  As shown in FIG. 5, the bag opening 101 serving as a receptacle for the body of the body storage bag 100 is provided with an opening / closing means 103 which can be sealed. By sealing the body storage bag 100 after housing the body, deterioration (oxidation) of the body can be suppressed. As the openable and closable means 103 which can be sealed, a concavo-convex fitting type sealing chuck, fusion sealing using a heater, adhesive sealing using an adhesive tape, or the like can be used. In the body storage bag 100 according to the embodiment, a double-purpose sealing chuck made of general-purpose synthetic resin asperity fitting type is used.

  The body storage bag 100 is provided with a check valve 105 for preventing the body storage bag 100 from bursting. The check valve 105 is a valve that can discharge the gas in the body storage bag 100 to the outside of the bag by a vacuum cleaner or a decompression pump, but prevents the gas outside the bag from flowing into the body storage bag 100. Although liquid nitrogen is vaporized to generate nitrogen gas, nitrogen gas is naturally discharged out of the bag by the check valve 105, so that it is possible to prevent the rupture of the morgue storage bag 100, and the morgue storage bag 100. Since inflow of an active gas such as oxygen can be prevented, deterioration (oxidation) of the body can be suppressed. The check valve 105 can use a general-purpose product, and in the body storage bag 100 of the embodiment, a lid forming valve manufactured by Sugawara Co., Ltd. is used.

  Next, the usage method of the body storage bag 100 of an embodiment, an effect, and an effect are explained. The storage of the body by the body storage bag 100 of the embodiment is performed according to the procedure of containing the body, a first cooling process of injecting liquid nitrogen, and a second cooling process of cooling in a low temperature environment.

  Containment of the body is to store the body in the body storage bag 100. At this time, it is preferable to remove any portable items (glasses, watches, pacemakers, etc.) unsuitable for cremation. This is because the body may be cremated while being contained in the body storage bag 100.

  The first cooling process is a process in which liquid nitrogen is injected from the bag opening 101 into the body storage bag 100 containing the body, and the body is made movable while maintaining the state found at the body detection place. It is. Since the body is rapidly cooled by liquid nitrogen, it can pass through the freezing temperature zone (-5 to 0 ° C.) of water contained in the body in a short time. For this reason, it is possible to freeze the dead without destroying the cells of the dead, and it is possible to prevent the deterioration of the dead. After injecting the liquid nitrogen into the body storage bag 100, the bag opening 101 is immediately closed by the sealable opening / closing means 103 of the bag opening 101. The reason is that the cold air is not leaked to the outside, and the body storage bag 100 is for blocking active gas such as oxygen. Although liquid nitrogen is vaporized to generate nitrogen gas in cooling the body, nitrogen gas is discharged to the outside of the bag by the check valve 105, so that it is possible to prevent the body storage bag 100 from bursting. The injection amount of liquid nitrogen is preferably 0.5 to 2 times the volume of the body by volume. It is because it is a quantity suitable for cooling of a body. If the injection volume is less than 0.5 times the volume of the body, the body can not be cooled rapidly, and the body may deteriorate. On the other hand, if the volume is more than twice, excessive cooling may occur. More preferably, the injection amount of liquid nitrogen is 0.8 to 1.5 times the volume of the body volume.

  The second cooling process is to cool and store the body together with the body storage bag 100 in a low temperature environment such as a freezer. The first cooling process can temporarily cool the body, but can not cool and preserve the body in the long run. Therefore, the body storage bag 100 (body) subjected to the first cooling treatment is cooled and stored in a low temperature environment such as a freezer. The cooling temperature in the second cooling treatment is preferably −60 to −20 ° C., because deterioration of the body can be prevented. If the cooling temperature is less than -60 ° C, although deterioration of the body can be prevented, it is excessive cooling and not preferable. On the other hand, if the temperature exceeds -20 ° C., there is a possibility that a piece of meat and the like of the body may deteriorate, and it may not be possible to maintain the state found at the body detection place. More preferably, the cooling temperature is −60 to −40 ° C. In addition, it is preferable to deaerate suitably using a pressure reduction pump etc. from check valve 105 during storage of a body. This is because the storage space for the body can be reduced, and active gas that may be generated unavoidably can be eliminated.

  In this way, the body housed in the body storage bag 100 is prevented from deterioration of the body, and even if it is an unidentified body or a part of the body, it retains the state of being found at the body detection place. It can be stored as it is. In addition, after the identity is identified, the remains can be incinerated with the crematorium together with the body storage bag 100. The inside of the body storage bag 100 is filled with noncombustible nitrogen, and there is no danger such as explosion. In addition, although PVC was used for the synthetic resin which forms the body storage bag 100 of embodiment, it is thought that PET resin or PBT resin is more preferable from a viewpoint of environmental conservation (suppression of the generation amount of dioxin).
