Hereinafter, with reference to accompanying drawing, a preferred embodiment of duct type regenerative apparatus involved in the present invention is described in detail.Fig. 1 is the sectional view of the duct type regenerative apparatus involved by present embodiment, Fig. 2 indicates that the heat-storing material utilizing the duct type regenerative apparatus of Fig. 1 to carry out discharges the sectional view in stage, Fig. 3 indicates that the sectional view utilizing the heat-storing material that the duct type regenerative apparatus of Fig. 1 carries out to cast the stage, and Fig. 4 indicates that the heat-storing material utilizing the duct type regenerative apparatus of Fig. 1 to carry out changes the sectional view of the completion status of operation.
Duct type regenerative apparatus 1 involved by present embodiment possesses vertically vertical direction and erects the straight vertical pipeline 2 of setting.Vertical pipeline 2 is formed as the upper end 2a hollow cylinder shape that open, lower end 2b opens downwards upward.The internal diameter of vertical pipeline 2 is formed as identical size from upper end 2a to lower end 2b.
The top of vertical pipeline 2 is connected to upper pipe 3.The bottom of vertical pipeline 2 is connected to lower pipeline 4.The end of the upper pipe 3 connected on vertical pipeline 2 is provided with porous plate (grid) 5.It also is provided with porous plate 6 in the end of the lower pipeline 4 being connected with vertical pipeline 2.
The exhaust emission tube 10 that be connected to the combustion air supply pipe 8 with steam supply valve 7 in lower pipeline 4, there is air bleeding valve 9.Combustion air supply pipe 8 is connected with air supply aerator (not shown) of supply combustion air A, and exhaust emission tube 10 is connected with the flue (not shown) discharging waste gas B.
Heat-accumulating burner is made up of the combustion event a pair burner unit with exhaust event that hocket.Respectively there is shown the major part of the burner unit of a side.Upper pipe 3 is towards the stove inner opening of such as work stove, and when carrying out combustion event, fuel mixes with the combustion air A (representing with solid arrow in figure) supplying pipe 8 supply from combustion air, generates flame in stove.When being exhausted action, the waste gas B (representing with dotted arrow in figure) in stove is attracted towards exhaust emission tube 10.
Circulate to upper pipe 3 from lower pipeline 4 via vertical pipeline 2 as it is shown in figure 1, supply pipe 8 from combustion air to the combustion air A of supply in stove.The waste gas B discharged from exhaust emission tube 10 is contrary with the flowing of combustion air A, circulates from upper pipe 3 via vertical pipeline 2 lower portion pipeline 4.That is, the circulation path of combustion air A and waste gas B make these combustion airs A and waste gas B mutually with contrary towards circulation, make combustion air A circulate to upper pipe 3 from lower pipeline 4, make waste gas B circulate from upper pipe 3 lower portion pipeline 4.Alternatively, it is also possible to make combustion air supply pipe 8 and exhaust emission tube 10 be connected with upper pipe 3, and replace and be connected with lower pipeline 4, make lower pipeline 4 be connected with inside stove.In a word, in the vertical pipeline 2 being arranged between upper pipe 3 and lower pipeline 4, alternately circulation has combustion air A and waste gas B.
The inside of vertical pipeline 2, at least in the space till above lower pipeline 4, contain the granular heat-storing material of ceramic etc., be the spherical heat-storing material 11 of spherical-like morphology in the present embodiment.Certainly, shown in the imaginary line D in Fig. 1, it is also possible to house spherical heat-storing material 11 in the space till near upper pipe 3 or above upper pipe 3.Thus, flow into circulate via spherical heat-storing material 11 from upper pipe 3, lower pipeline 4 at the combustion air A and waste gas B of vertical pipeline 2 internal flow, thus contacting with this spherical heat-storing material 11.
Spherical heat-storing material 11, when waste gas B circulates, reclaims used heat from waste gas B, and when combustion air A circulates, heats combustion air A by the used heat reclaimed.The porous plate 5,6 of upper pipe 3 and lower pipeline 4 makes combustion air A, waste gas B circulate, and keeps spherical heat-storing material 11 avoiding spherical heat-storing material 11 to drop from vertical pipeline 2 is internal to upper pipe 3, lower pipeline 4.
The inner face 2c that porous plate 5,6 is arranged to face to surface 5a, the 6a within vertical pipeline 2 and vertical pipeline 2 is substantially coplanar, thus, as described later by spherical heat-storing material 11 from when discharging inside vertical pipeline 2, spherical heat-storing material 11 can fall swimmingly, will not remain in the periphery of porous plate 5,6.
The upper end 2a of vertical pipeline 2 is provided with the feeding hopper 12 for supplying spherical heat-storing material 11 inside vertical pipeline 2.Feeding hopper 12 such bottom as is well known is formed by the inclined plane tilted towards the direction of the supply.
The opening of the lower end 12a of feeding hopper 12 is formed with the size roughly the same with the size of the opening of vertical pipeline 2.Before supplying spherical heat-storing material 11 inside vertical pipeline 2, from spherical heat-storing material feed path 13 spherical heat-storing material 11 sent in feeding hopper 12 in advance and store.Storage capacity once is set as the replacing total amount of spherical heat-storing material 11.
Between the lower end 12a and the upper end 2a of vertical pipeline 2 of feeding hopper 12, opening and closing is provided with upper portion door 14 freely.By closing upper portion door 14, thus by feeding hopper 12 and vertical pipeline 2 interior separations, spherical heat-storing material 11 being maintained in feeding hopper 12.Meanwhile, upper portion door 14 makes the internal maintenance of vertical pipeline 2 airtight.On the other hand, by opening upper portion door 14, making feeding hopper 12 and vertical pipeline 2 inside connect, from feeding hopper 12 to vertical pipeline 2, spherical heat-storing material 11 is cast in inside.
In the present embodiment, upper portion door 14 is slided driving in the horizontal direction so that the door-plate 14a separation close to each other of pair of right and left top, by close to and upper portion door 14 is closed, by separation, upper portion door 14 is opened.Each top door-plate 14a preferable separate drives the position of the upper end 2a standard-sized sheet to vertical pipeline 2.As driving mechanism, for instance, it is possible to use hydraulic cylinder etc..
Lower end 2b opening and closing at vertical pipeline 2 is provided with lower gate 15 freely.By closing lower gate 15, thus cutting off internal for vertical pipeline 2 and outside, spherical heat-storing material 11 is maintained at vertical pipeline 2 internal.Meanwhile, lower gate 15 makes the internal maintenance of vertical pipeline 2 airtight.On the other hand, by opening lower gate 15, make vertical pipeline 2 internal and ft connection, discharge spherical heat-storing material 11 from vertical pipeline 2 is internal.
In the present embodiment, lower gate 15 is with biparting mode driven for opening and closing, so that pair of right and left lower gate plate 15a separation close to each other.Specifically, the cardinal extremity of each lower gate plate 15a is located at the fulcrum 15b of the Outboard Sections of vertical pipeline 2 and is rotatably supported, each lower gate plate 15a rotates around cardinal extremity, close to each other thus lower gate 15 is closed by the front end 15c that makes them, by making their front end 15c separate, thus lower gate 15 is opened.
Thus, each lower gate plate 15a separate mobile is to the position of the lower end 2b standard-sized sheet of vertical pipeline 2.As driving mechanism, for instance, it is possible to use gear mechanism etc..
Lower gate 15 can also be identical with upper portion door 14, realizes opening and closing by driving of sliding in the horizontal direction.It addition, upper portion door 14 can also be identical with lower gate 15, and with biparting mode driven for opening and closing.
Drive according to sliding, then can reduce and required size up and down is set, it is possible to make duct type regenerative apparatus 1 miniaturization.On the other hand, when when there is excess room up and down of vertical pipeline 2, it is arranged to biparting splitting and can instantaneous and promptly carry out the supply of spherical heat-storing material 11, discharge.
In the present embodiment, in order to make lower gate plate 15a lightweight, and at the lower surface configuration ribs 15d of this lower gate plate 15a, thus achieve the thin-walled property of lower gate plate 15a.It addition, in illustrated example, lower gate 15 be arranged below into clearance spaces, but the drain tank being discharged to guide to spherical heat-storing material 11 can also be set immediately below lower gate 15.
Lower pipeline 4 is connected to the lower end 2b position by the top than the vertical pipeline 2 being provided with lower gate 15, is thus formed with bottom section C at the lower end 2b periphery of vertical pipeline 2.Once waste gas B etc. enter, then the ratio pressure stability of bottom section C of the lower end 2b periphery of lower pipeline 4 vertical pipeline 2 on the lower, hinder waste gas B etc. after therefore to the circulation of this bottom section C.
That is, waste gas B etc. will not enter bottom section C, combines with spherical heat-storing material 11 air layer each other, it is possible to present thermal insulation.Therefore, it is possible to prevent lower gate 15 periphery from heating to high temperature.Therefore, it is possible to cut down the heat proof material of downward department 15 construction, it is possible to realize the lightweight of lower gate 15, cost degradation.
Being configured with returnable 18 on the face that arranges 17 of duct type regenerative apparatus 1, this returnable 18 is positioned at below vertical pipeline 2, reclaims the spherical heat-storing material 11 discharged from lower gate 15.Returnable 18 has peristome 18a upward.As long as spherical heat-storing material 11 can be housed, then returnable 18 just can adopt the container of any forms such as box-shaped state.In the present embodiment, in order to improve the convenience of movement, it is provided with in returnable 18 and the wheel 18b travelled on face 17 freely is being set.
Duct type regenerative apparatus 1 possesses controller 19, and this controller 19 is connected with upper portion door 14, lower gate 15, steam supply valve 7 and air bleeding valve 9 and they are controlled.
Steam supply valve 7 opens (opening action represents in the drawings) with open symbols when heat-accumulating burner carries out combustion event, and the combustion air A supplying pipe 8 from combustion air sends into from vertical pipeline 2 to upper pipe 3.Mix with fuel after sending into the combustion air A of upper pipe 3, in stove, thus generate flame.Now, air bleeding valve 9 closes (closing motion represents in the drawings) with closed symbols.On the other hand, when heat-accumulating burner is exhausted action, steam supply valve 7 cuts out and air bleeding valve 9 is opened, and thus, from the waste gas B in stove via upper pipe 3 to vertical pipeline 2 internal circulation, afterwards, discharges to exhaust emission tube 10.
The burner unit of a side for the paired burner unit of heat-accumulating burner, when closing air bleeding valve 9 and opening steam supply valve 7 and make the combustion event of the combustion air A state circulated in vertical pipeline 2 (burner unit of the opposing party is in exhaust event state), if controller 19 cuts out steam supply valve 7 and inputs this operation signal from steam supply valve 7, then can carry out the replacement operation of spherical heat-storing material 11.Or, if when carrying out combustion event, have the shutdown signal of steam supply valve 7 to controller 19 input, then can trigger, by this input operation, the replacement operation implementing spherical heat-storing material 11.
Making the air-flow in vertical pipeline 2 temporarily cease correspondingly with closing steam supply valve 7, from controller 19, downward department 15 sends opening signal.Afterwards, in the timing of the timer etc. possessed by controller 19, according to when have passed through stipulated time etc. and confirm that whole spherical heat-storing materials 11 falls into returnable 18, downward department 15 sends shutdown signal.Afterwards, after confirmation lower gate 15 such as passing through the sensor of opening and closing of detection lower gate 15 is closed, opening signal is sent from controller 19 to upper portion door 14.
Afterwards, in the timing of the timer etc. by controller 19, according to have passed through stipulated time etc. and confirm whole spherical heat-storing materials 11 from feeding hopper 12 put in vertical pipeline 2 time, send shutdown signal from controller 19 to upper portion door 14.Finally, after confirmation upper portion door 14 such as passing through the sensor of opening and closing of detection upper portion door 14 is closed, sending opening signal from controller 19 to air bleeding valve 9 and make the burner unit of this side be changed into exhaust event, thus, the burner unit paired the opposing party starts combustion event.
The action control of valve 7,9 and door 14,15 can also accumulative not against the timer etc. of controller 19, and confirm situation by staff by visualization while operating controller 19 to carry out opposite house 14,15 and valve 7,9 carries out opening and closing operations.In this case, controller 19 also cuts out as condition with air bleeding valve 9, closes, with steam supply valve 7, the control correspondingly allowing replacement operation.Therefore, the control of replacement operation forbidden by controller 19 when the exhaust event that air bleeding valve 9 is opened.
It follows that the effect of the duct type regenerative apparatus 1 involved by present embodiment is illustrated.Fig. 1～Fig. 4 is by the step of the replacement operation illustrating spherical heat-storing material 11 successively.The burning operating condition of the burner unit of side when Fig. 1 illustrates the normal operation of heat-accumulating burner.
Opening steam supply valve 7 when carrying out combustion event and close air bleeding valve 9, combustion air A supplies pipe 8 from combustion air and circulates to upper pipe 3 via vertical pipeline 2.The replacement operation of spherical heat-storing material 11 is carried out when this combustion event.
As in figure 2 it is shown, first, on the face that arranges 17 below vertical pipeline 2, in the way of lower gate 15, returnable 18 is configured by peristome 18a upward.It addition, storage has the spherical heat-storing material 11 changing total amount in feeding hopper 12.It follows that close steam supply valve 7.Thus, the circulation of combustion air A is stopped.Now, the supply of fuel is also stopped.
Afterwards, lower gate 15 is opened by controller 19.Thus, the spherical heat-storing material 11 within vertical pipeline 2 instantaneous and at a heat from lower gate 15 to returnable 18 discharge.It follows that close lower gate 15 by controller 19.
It follows that as it is shown on figure 3, open upper portion door 14 by controller 19.Thus, the spherical heat-storing material 11 in feeding hopper 12 is instantaneous and cast in vertical pipeline 2 from upper portion door 14 at a heat.
Afterwards, as shown in Figure 4, upper portion door 14 is closed by controller 19.Afterwards, air bleeding valve 9 is opened.Thus, in the burner unit of this side, waste gas B goes into circulation and is changed into aerofluxus operating condition, meanwhile, starts burning operating in the burner unit of the opposing party.Returnable 18 is carried to cleaning equipment etc. the suitable opportunity after lower gate 15 is closed.Supplied to feeding hopper 12 from spherical heat-storing material feed path 13 by the spherical heat-storing material 11 after the method regeneration such as cleaning and be reused.
In the duct type regenerative apparatus 1 involved by present embodiment described above, spherical heat-storing material 11 is contained in the vertical pipeline 2 of form straight along the vertical direction, therefore, discharge operation when no matter being change spherical heat-storing material 11, or cast operation for what refill, can fulfil assignment instantaneous and at a heat all without producing blocking such that it is able within the very short time, be quickly accomplished the replacing operation of whole spherical heat-storing material 11.
Therefore, it is possible to simplify the maintenance of the heat-accumulating burner being object with spherical heat-storing material 11.Further, since whole spherical heat-storing material 11 can be changed without a break, thus without bad phenomenon such as spherical heat-storing material 11 residuals all the time that generation is not changed, it is possible to increase the management of equipment.
In the present embodiment, the opening of the lower end 12a of feeding hopper 12 is formed with the size roughly the same with the size of the opening of vertical pipeline 2, and, by substantially coplanar for inner surface 2c that porous plate 5,6 is arranged to face to surface 5a, the 6a within vertical pipeline 2 and vertical pipeline 2, spherical heat-storing material 11 is remained, it is possible to more smooth and easy and be properly completed replacing operation thus without at these feeding hoppers 12 and porous plate 5,6 periphery.
Particularly, in discharging operation, if opening lower gate 15 just can be expelled directly out whole spherical heat-storing material 11 such that it is able to remove and draw loaded down with trivial details operations such as taking spherical heat-storing material 11.Further, since be vertical pipeline 2, therefore construct very simple, from regardless of whether cast spherical heat-storing material 11 or discharge it, preventing from thus producing damage.
There is returnable 18 vertical pipeline 2 is configured under, reclaim spherical heat-storing material 11 by returnable 18, therefore, it is possible to easily the spherical heat-storing material 11 discharged is moved to other positions.
The bottom section C with thermal insulation is formed by utilizing ribs 15d to strengthen lower gate plate 15a, directly over lower gate 15, it is able to ensure that the thin-walled property of lower gate plate 15a and the reduction of the construction volume of heat proof material, thus, the on-off action time of lower gate 15 can be shortened, it is possible to shorten further and change the activity duration.
Spherical heat-storing material 11 change operation only by the opening and closing operations of lower gate 15 and upper portion door 14 just it is achieved that it is thus possible to easily fulfil assignment at short notice, it is possible to shorten during the operating of heat-accumulating burner stops.
Owing to lower gate 15 is set to biparting splitting, therefore can be instantaneous and promptly discharge spherical heat-storing material 11 compared with slidingtype, thus it also is able to promote the shortening of replacing construction.
Lower pipeline 4 is connected to the combustion air supply pipe 8 with steam supply valve 7 and the exhaust emission tube 10 with air bleeding valve 9, when closing air bleeding valve 9 and opening steam supply valve 7 and make combustion air A circulate in vertical pipeline 2, action with closedown steam supply valve 7 is correspondingly, the on-off action of upper portion door 14 is carried out after the on-off action of lower gate 15, therefore forbid changing operation during high-temp waste gas B circulation, and on the other hand during combustion air A circulates, the supply of combustion air A is only stopped when changing operation, stopped by this supply, namely the shutoff operation of steam supply valve 7 is tried one's best and is suppressed the variation of in-furnace temperature, even and if also being able to carry out the replacing operation of spherical heat-storing material 11 in during the operating of heat-accumulating burner.
It addition, be replaced operation when the combustion air A of low temperature circulates, therefore, it is possible to reduce the temperature of spherical heat-storing material 11 and discharge it, it is possible to increase the safety of operation.
And, in the burner unit of a side, complete the replacing operation of spherical heat-storing material 11 and switch to aerofluxus operating after upper portion door 14 being closed, therefore the burner unit of the opposing party can be switched to burning operating from aerofluxus operating at once correspondingly, it is thus possible to guarantee continuously running of heat-accumulating burner while the replacing operation carrying out spherical heat-storing material 11, it is possible to continuously stove is operated.
Additionally, the spherical heat-storing material 11 of the low temperature after just changing first is heated by waste gas B when aerofluxus operates thus accumulation of heat, intensification, therefore when burning later operates, the situation of combustion air A circulation is issued to enough conditions of high temperature, it is thus possible to suitably heat this combustion air A, the flame temperature generated in stove is maintained higher temperature.
It addition, when operating multiple heat-accumulating burner, made the heat-accumulating burner of one party shut down by intermittent operation.It is of course possible to be replaced operation in during this operating stops.
Owing to bottom section C has thermal insulation, vertical pipeline 2 part therefore forming this bottom section C can not use refractory material to be formed by iron shell.The production costs that can reduce vertical pipeline 2 is set like this.
It should be noted that, for granular heat storage, be illustrated for the spherical heat-storing material 11 of spheroid form, however granular be not limited to spherical, as long as ellipticity or cylindrical shape, breaked shape etc. present the form of rollability, then it can be arbitrary form.For spherical, without being positive spheroid, and can be there is deformation or concavo-convex spherical.
