Detailed Description
The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, a multi-valve-group heat-accumulating high-temperature oxidation system disclosed in an embodiment of the present application is composed of air chambers 11, heat accumulators 12, combustion chambers 13, air chambers 21, connecting pipes 22, raft layers 23, driving devices 24, and the like, specifically, the number of the air chambers 11 is the same as that of the heat accumulators 12, each air chamber 11 is fixed with one heat accumulator 12, the air chamber 11 is further communicated with the heat accumulator 12 fixed thereon, gas in the air chamber 11 can flow into the heat accumulator 12, and gas in the heat accumulator 12 can also flow into the air chamber 11.
The number of combustion chambers 13 is one, and is fixed to the regenerator 12 and communicates with each regenerator 12, for example, the number of regenerators 12 is three, so that the combustion chamber 13 has three connecting ends, each connecting end is connected to one regenerator 12, the gas in the regenerator 12 can enter the combustion chamber 13, and the gas in the combustion chamber 13 can also enter the regenerator 12.
Each of the air chambers 11 is provided with two air chambers 21, and the two air chambers 21 are symmetrically disposed at both sides of the air chamber 11 and are respectively connected to a pair of opposite sidewalls of the air chamber 11 and communicate with the space inside the air chamber 11.
Each gas chamber 21 is provided with a connecting pipe 22, and the connecting pipe 22 is connected with an air inlet pipe or an air outlet pipe and is used for introducing gas to be processed into the gas chamber 21 or leading processed gas out of the gas chamber 21.
Referring to fig. 2 and 3, two raft layers 23 are further installed in each air chamber 21, each raft layer 23 is composed of an outer frame 231 fixed on the inner wall of the air chamber 21 and a plurality of rafts 232 rotatably connected to the outer frame 231, and each raft 232 has two states, one is in an open state and the other is in a closed state.
When the raft 232 is in the open state, the gas in the gas chamber 21 can flow in or out through the connecting pipe 22; when the raft 232 is in the closed state, the gas in the gas chamber 21 does not flow.
The power when raft 232 rotates is provided by drive arrangement 24, and drive arrangement 24 is located the air chamber 21 and is located the air chamber 21 outside, can drive raft 232 and rotate. The reason why the driving device 24 is disposed outside the air chamber 21 is to prevent high temperature and impact from affecting the normal operation of the driving device 24, which can make the service life of the driving device 24 longer.
In combination with a specific use process, the gas to be treated firstly flows into the first air chamber 21, the rafts 232 in the air chamber 21 are rotated to be in an open state, the gas in the air chamber 21 flows into the air chamber 11, then passes through the regenerator 12 and finally enters the combustion chamber 13 for combustion.
The gas burned in the combustion chamber 13 enters the regenerator 12, exchanges heat with the heat storage body in the regenerator 12, and is discharged from the gas chamber 21 through the wind chamber 11.
In the above-mentioned process, the pressure that the air was exerted can disperse on each raft 232, compares and uses integral raft structure, and the pressure that raft 232 under this kind of structure bore is littleer, and reflection speed also can obtain improving. From another perspective, it is understood that the rotation radius of the raft 232 is reduced, and under the condition that the wind pressure is not changed, the moment arm is shortened equivalently, and the pressure born by the raft 232 can also be effectively reduced.
The driving device 24 can switch the state of the rafts 232 in a shorter time, and the reaction speed can be increased to a certain extent. In addition, the two layers of rafts 232 can bear the impact generated by gas during air intake and exhaust respectively, so that the service life of the rafts 232 can be further prolonged.
Referring to fig. 4(a) and 4(B), as a specific embodiment of the multi-valve-group heat-accumulating high-temperature oxidation system provided by the application, a first inclined surface 233 is added on the top surface of each raft 232, a second inclined surface 234 is added on the bottom surface of each raft 232, and the first inclined surface 233 and the second inclined surface 234 function to improve the sealing performance between adjacent rafts 232.
It will be appreciated that in general, the rafts 232 are rectangular in shape and therefore the direction of the gaps between adjacent rafts 232 remains substantially the same as the direction of the airflow within the air chamber 21, which results in poor sealing between adjacent rafts 232.
After first inclined plane 233 and second inclined plane 234 have been increased, can change the gap direction between adjacent raft 232, increase the gap length between adjacent raft 232 simultaneously, can promote the leakproofness between raft 232.
For example, when the rafts 232 are in a closed state, the first inclined surfaces 233 abut against the adjacent second inclined surfaces 234, so that the passing length of gaps between the adjacent rafts 232 can be increased, the orientation of the gaps can be changed, the two aspects are overlapped, and the sealing performance between the rafts 232 can be better.
Furthermore, a sealing strip 235 and a sealing groove 236 are respectively added on the first inclined surface 233 and the second inclined surface 234, the axis of the sealing strip 235 is parallel to the rotating shaft of the raft plate 232 when rotating, and the axis of the sealing groove 236 is parallel to the rotating shaft of the raft plate 232 when rotating.
When raft 232 is in the closed condition, sealing strip 235 can enter into in the seal groove 236 for the complexity of the gap shape between adjacent raft 232 further improves, and of course, the length of passing through of gap also can obtain increasing, can be so that the leakproofness between raft 232 is better.
Referring to fig. 3, as a specific embodiment of the multi-valve-group heat-storage high-temperature oxidation system, the driving device 24 is composed of a bracket 241, a driver 242, a transmission shaft 243, a driving gear 244, a driven gear 245 and the like, the bracket 241 is fixedly installed on the outer wall of the air chamber 21, and the driver 242 is fixedly installed on the bracket 241.

Adjacent driven gears 245 mesh, and the drive gear 244 meshes with one of the driven gears 245.
In the working process, the driver 242 drives a plurality of driven gears 245 to rotate through the transmission shaft 243 and the driving gear 244, so that the raft 232 is opened and closed.
The driving gear 244 and the driven gear 245 may be covered with a protective cover fixedly installed on the air chamber 21, and one end of the driving shaft 243 is inserted into the protective cover.
Referring to fig. 2, as an embodiment of the multi-valve bank heat accumulation high temperature oxidation system provided by the application, the bottom ends of the first layer of raft slabs 23 and the second layer of raft slabs 23 are inclined toward the direction close to the plenum 11 in the direction away from the connecting pipe 22.
In combination with a specific process, in the air intake process, the airflow firstly passes through the first raft layer 23, and after the first raft layer 23 is opened, the airflow impacts the second raft layer 23, but because the second raft layer 23 is inclined, the impact force borne by the airflow is smaller.
In the exhaust process, the airflow will firstly pass through the second layer of raft layers 23, and after the second layer of raft layers 23 is opened, the airflow will impact the first layer of raft layers 23, but because the first layer of raft layers 23 are inclined, the impact force is smaller.
As a specific implementation of the multi-valve-group heat storage high-temperature oxidation system provided by the application, in the air intake process, the opening time of the second layer raft layer 23 lags behind the opening time of the first layer raft layer 23, so that the backflow of gas caused by air pressure can be reduced.
Specifically, the analysis is as follows, in the air inlet process, the air flow needs to flow through the second layer raft layer 23 from right to left, at this time, the first layer raft layer 23 is firstly opened, the air pressure on the right side of the second layer raft layer 23 is increased, at this time, the second layer raft layer 23 is opened again, and therefore the air flow on the left side of the second layer raft layer 23 can be prevented from entering the air chamber 21.
Referring to fig. 5 to 7, as a specific embodiment of the multi-valve-group heat storage high-temperature oxidation system provided by the application, sealing rings 31 are added to two sides of the outer frame 231, and the sealing rings 31 can be pressed at the junction of the outer frame 231 and the raft 232, so as to further improve the sealing performance of the raft layer 23.
Each outer frame 231 is fixed with a guide post 32, a first end of the guide post 32 is fixed on the sealing ring 31, a second end of the guide post 32 penetrates through the outer frame 231 and the other sealing ring 31, and the guide post 32 is used for limiting the movement of the sealing ring 31 according to a set movement track.
When raft 232 opened, can promote two sealing rings 31 and remove to the direction of keeping away from each other, when raft 232 closed, these two sealing rings just need to remove and paste in the juncture of frame 231 and raft 232 to the direction of being close to each other.
The power of the sealing rings 31 approaching each other is provided by springs 33, and both ends of the springs 33 are respectively fixed to the adjacent sealing rings 31, and the middle portions thereof pass through the through holes of the outer frame 231.
Further, referring to fig. 8, a conduit 34 is added to the sealing ring 31, one end of the conduit 34 connected to the sealing ring 31 is communicated with the sealing ring 31, the other end is a closed end, and both ends of the spring 33 are located in the conduit 34 and fixed on the closed end of the conduit 34.
