  EMBODIMENT OF THE INVENTION Below, suitable embodiment of the thermal storage type deodorizing apparatus concerning this invention is described in detail with reference to an accompanying drawing. 1 is a front view of a heat storage deodorizing apparatus according to the present embodiment, FIG. 2 is a plan view of the heat storage deodorizing apparatus shown in FIG. 1, and FIG. 3 is a heat storage section of the heat storage deodorizing apparatus shown in FIG. FIG. 4 is a view as seen from the direction of the arrow A in FIG.

  As shown in FIGS. 1 and 2, the heat storage deodorization apparatus 1 according to the present embodiment includes a heating chamber 3 made of a square tube-shaped heat-resistant steel material having a burner 2 at the center, and both ends in the length direction of the heating chamber 3. A plurality of, in the illustrated example, two heat storages, which are arranged and joined to the heating chamber 3 side by side and to the side of the heating chamber 3 to form a flow path communicating with the heating chamber 3 so as to circulate gas. Part 4, supply system 5 capable of supplying a gas to be deodorized to each heat storage part 4, blower 6 connected to supply system 5, and gas heated in heating chamber 3, either heat storage part 4 is provided in the exhaust system 7 that can be discharged through the passage 4, the supply system 5 and the two connection parts 8 that connect the exhaust system 7 and the respective heat storage parts 4, and the supply system 5 and the exhaust system 7. An open / close damper 9 for opening and closing the system 5 and the exhaust system 7; Part 4 and and a grating 10 for partitioning between the connecting portion 8.

  The heating chamber 3 is formed, for example, in a rectangular tube shape having a square shape with a side of about 2000 mm. The heating chamber 3 has its penetrating direction oriented horizontally, and inclined portions 3a each having a tip inclined downward are formed at both ends. The burner 2 is disposed on one of the four walls of the heating chamber 3 having a rectangular tube shape so as to generate a flame toward the inner side of the heating chamber 3.

  The two heat storage units 4 have the same configuration. Each heat storage unit 4 is configured by housing a plurality of heat storage materials for exchanging heat when gas passes in an outer peripheral member 11 formed of the same rectangular tubular heat-resistant steel material as the heating chamber 3. In the outer peripheral member 11, a portion corresponding to one side of the square constitutes the bottom surface of the heat storage unit 4. Further, the outer peripheral member 11 is arranged to be inclined with the same inclination as the inclined portions 3 a at both ends of the heating chamber 3. That is, the inclined portion 3a of the heating chamber 3 and the outer peripheral member 11 of the heat storage portion 4 are linearly connected.

  As shown in FIG. 3, a castable 12 is provided on the lower surface in the outer peripheral member 11. On the castable 12, as a plurality of heat storage bodies, for example, a ceramic-type heat storage block 13 made of ceramic having air permeability is stacked on the side wall 11 a and the upper surface 11 b of the outer peripheral member 11 at intervals. Between the heat storage block 13 and the outer peripheral member 11 stacked, a blanket 14 such as a lightweight and soft glass wool is filled so as to cover the heat storage block 13, in other words, to wrap around the heat storage block 13. The heat storage blocks 13 are each formed in the same rectangular parallelepiped shape. In short, the heat storage block 13 is installed between the heating chamber 3 and the connecting portion 8 so that gas can be circulated.

  As shown in FIG. 3, a plurality of heat storage blocks 13 are arranged on the castable 12 in the depth direction as the gas flow direction and in the direction intersecting the depth direction as viewed from the heating chamber 3 side, and are directed upward in the vertical direction. It is provided by stacking. In the present embodiment, three rows are arranged in the depth direction, and nine steps are stacked in the vertical direction in the row closest to the heating chamber 3, and the number of steps increases by one as approaching the grating 10 side.

  The heat storage block mounting surface 12a configured by the upper surface of the castable 12 is provided with a step whose height decreases in each row from the heating chamber 3 side to the grating 10 side. In other words, a level difference is provided for each row as it approaches the heating chamber 3 side from the grating 10 side. This step is set to a height that is half the height of the heat storage block 13. By this step, the upper surfaces of the heat storage blocks 13 adjacent to each other in the gas flow direction do not form the same plane in a state where the plurality of heat storage blocks 13 are stacked. Moreover, in the state in which the plurality of heat storage blocks 13 are stacked, the positions of the heat storage blocks 13 overlapping in the vertical direction are also half the width of the heat storage block 13 in the left-right direction (the direction intersecting the gas flow direction). Stacked so as to be displaced. Furthermore, in a state where the plurality of heat storage blocks 13 are stacked, the heat storage blocks 13 that are adjacent to each other in the gas flow direction are stacked at different positions along the direction intersecting the gas flow direction. When there is a portion with insufficient dimensions on the side wall 11a side of the outer peripheral member 11, a heat storage block that supplements the dimensions, such as a half-size heat storage block 13a, is disposed.

  In the heat storage unit 4, the grating 10 is arranged on the entire surface of the opening connected to the connecting unit 8, and the heat storage blocks 13 are arranged on the castable 12 in order from the column on the grating 10 side, and are sequentially stacked on the heating chamber 3 side. At this time, the outer peripheral member 11 and the castable 12 constituting the heat storage unit 4 are each placed on the castable 12 because they are inclined obliquely downward in the direction away from the heating chamber 3, that is, toward the grating 10 side. The weight (gravity) acts on the heat storage block 13 in the direction away from the heating chamber 3, and the weight is supported by the grating 10. The structure is not limited to the grating 10 as long as the weight can be supported without breaking the heat storage block 13 and air permeability can be secured.

  After the heat storage blocks 13 are stacked, the blanket 14 is filled between the stacked heat storage blocks 13 and the outer peripheral member 11. For this reason, when replacing the heat storage block 13, if the blanket 14 is removed, the heat storage block 13 can be easily taken out and replaced easily.

  The supply system 5 and the exhaust system 7 are connected to a connecting part 8 connected to the heat storage parts 4 on both sides of the heating chamber 3. That is, the supply system 5 and the exhaust system 7 are connected to each connecting portion 8.

  As shown in FIGS. 1, 2, and 4, the supply system 5 is connected to the connecting portion 8, connected to the supply branch pipe 5 a drawn in the gas flow direction, the blower 6, and parallel to the heating chamber 3. A supply main pipe 5b arranged side by side with the heating chamber 3 in a direction crossing the gas flow direction, and two supply branch pipes 5a drawn to both sides of the heating chamber 3 in the gas flow direction. A supply communication pipe 5c that communicates with the supply main pipe 5b is provided. Each supply branch pipe 5a is provided with an open / close damper 9. The supply main pipe 5b connects the supply branch pipes 5a of the heat storage units 4 to each other in the gas flow direction.

  The exhaust system 7 is connected to the connecting portion 8 and connected to an exhaust branch pipe 7a drawn in the gas flow direction and a suction blower (not shown), and is arranged in parallel with the heating chamber 3 so that the gas flows. An exhaust main pipe 7b arranged side by side with the heating chamber 3 in a direction crossing the direction, and two exhaust branch pipes 7a and an exhaust main pipe 7b drawn to both sides of the heating chamber 3 in the gas flow direction, respectively. It has the exhaust communication pipe 7c which communicates. Each exhaust branch pipe 7a is provided with an open / close damper 9. The exhaust main pipe 7b connects the exhaust branch pipes 7a of the heat storage units 4 to each other in the gas flow direction.

  As shown in FIG. 4, the supply branch pipe 5 a and the exhaust branch pipe 7 a are both drawn out from the connecting portion 8 to a lower position on the floor side in the room where the heating chamber 3 is installed. The supply branch pipes 5a and the exhaust branch pipes 7a located on both sides of the heating chamber 3 are arranged side by side in a direction crossing the gas flow direction.

  As shown in FIG. 4, the supply main pipe 5b and the exhaust main pipe 7b are arranged on the same side with respect to the heating chamber 3 in the direction intersecting with the gas flow direction, with an interval in the vertical direction. The In the illustrated example, the supply main pipe 5b is positioned on the lower side, and the exhaust main pipe 7b is positioned on the upper side. For this reason, the supply communication pipe 5c is disposed horizontally to connect the supply branch pipe 5a and the supply main pipe 5b, and the exhaust communication pipe 7c is raised upward to the same height as the exhaust main pipe 7b. The tube 7b is connected almost horizontally.

  The burner 2 is provided with respect to the heating chamber 3 on the same side as the supply main pipe 5b and the exhaust main pipe 7b. Thereby, a burner facility can be installed between the supply main pipe 5b and the exhaust main pipe 7b which are spaced apart from each other in the vertical direction, and space saving can be achieved.

  The regenerative deodorization apparatus 1 includes an open / close damper 9 disposed on one side of the heating chamber 3 in the gas flow direction of the supply system 5 in a state where the blower 6 is operated by a control device provided outside. The open / close damper 9 disposed on the other side of the heating chamber 3 in the gas flow direction of the exhaust system 7 is simultaneously opened, and the open / close disposed on the other side of the heating chamber 3 in the gas flow direction of the supply system 5. The opening / closing operation in which the damper 9 and the opening / closing damper 9 disposed on one side of the heating chamber 3 in the gas flow direction of the exhaust system 7 are simultaneously closed and the opening / closing operation opposite to this are alternately performed. Thus, when the gas to be deodorized supplied from one side of the heating chamber 3 is heated in the heating chamber 3 and deodorized, when the gas is exhausted from the other side, heat is exchanged by the heated exhaust. After the heat is stored in the heat storage block 13 on the other side, the opening / closing of the open / close damper 9 is switched. Thereafter, when the gas to be deodorized supplied from the other side of the heating chamber 3 passes through the other heat storage block 13 where heat is stored, it is preheated by heat exchange, and the preheated gas is heated in the heating chamber 3. When deodorized, when the exhaust gas is exhausted from one side, heat exchange is performed by the heated exhaust gas, and heat is stored in the heat storage block 13 on one side, and then the opening / closing of the open / close damper 9 is switched again. By repeating such an operation, it is efficiently deodorized.

  According to the heat storage deodorizing apparatus 1 according to the present embodiment, the gas circulates substantially horizontally and horizontally through the heating chamber 3 that heats and deodorizes the gas to be deodorized and the heat storage units 4 provided on both sides thereof. Since it arrange | positioned side by side so that a flow path may be comprised, the height of the thermal storage deodorizing apparatus 1 whole can be restrained low. Since the heat storage section 4 in which the heat storage blocks 13 are stacked is inclined obliquely downward toward the direction away from the heating chamber 3, gravity acts on the stacked heat storage blocks 13 in the direction away from the heating chamber 3. This can be supported by the grating 10. For this reason, even if the wind pressure of the gas supplied from the supply system 5 acts, it can prevent that the heat storage block 13 moves. For this reason, the height of the heat storage deodorizing apparatus 1 can be suppressed, and at the same time, the movement of the heat storage block 13 can be prevented.

  Since the heat storage unit 4 has the castable 12 at the lower part on which the heat storage block 13 is placed and the lighter and softer blanket 14 at the upper side, the heat storage unit 4 can be reduced in weight while having the strength to hold the heat storage block 13. Since the upper side is the blanket 14 and the heat storage material is a heat storage block 13 in the form of a block, maintenance such as easily replacing the heat storage block 13 can be easily performed as necessary.

  Since the plurality of stacked heat storage blocks 13 are arranged such that the heat storage blocks 13 adjacent to each other in the gas flow direction are shifted from each other along the direction intersecting the gas flow direction. The heat storage blocks 13 that are adjacent to each other in the direction regulate the movement of each other, whereby the heat storage deodorizing apparatus 1 in which the heat storage block 13 is more difficult to move can be provided.

  Since the upper surface of the castable 12 on which the heat storage block 13 is stacked is provided with a step which becomes higher as it approaches the heating chamber 3 side, the heat storage block 13 on the heating chamber 3 side becomes higher and ensures a blocking action. This can more reliably prevent the heat storage block 13 from moving toward the heating chamber 3.

  A supply main pipe 5b connected to two supply branch pipes 5a provided on both sides of the heating chamber 3 and an exhaust main pipe 7b connected to two exhaust branch pipes 7a provided on both sides of the heating chamber 3 Since the heating chamber 3 is arranged on the same side in the direction intersecting the gas flow direction, the installation space can be reduced in addition to the height being reduced.

  In the said embodiment, although the outer peripheral member 11 of the heating chamber 3 and the heat storage part 4 was made into the square cylinder shape, it may not be restricted to this, for example, may be circular shape. In this case, as shown in FIG. 5, a castable 12 is provided on the inner peripheral surface of the lower semicircular portion of the circular outer peripheral member 11, and the upper portion of the castable 12 is directed toward the inner peripheral surface of the upper semicircular portion. The heat storage blocks 13 are stacked, and the blanket 14 may be filled between the stacked heat storage blocks 13 and the inner peripheral surface of the upper semicircular portion.

  FIG. 6 is an explanatory view for explaining another embodiment of the heat storage deodorizing apparatus according to the present invention, wherein (a) is a plan view and (b) is a side view. In the above-described embodiment, the case where the two heat storage units 4 are arranged in a face-to-face manner with the heating chamber 3 interposed therebetween is described. However, the heat storage unit 4 may be three or more, or in a face-to-face manner. It may not be arranged. For example, as shown in FIG. 6, four heat storage units 4 are arranged side by side on one side of the heating chamber 3, and the gas flow is switched in order. It may be used.
