Detailed Description
The technical solutions in the present application are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 and fig. 2, in order to disclose a multi-valve-group regenerative high-temperature oxidation system according to an embodiment of the present application, the system is composed of air chambers 11, regenerators 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 regenerators 12, each air chamber 11 is fixed with one regenerator 12, the air chambers 11 are also communicated with the regenerators 12 fixed thereon, gas in the air chambers 11 can flow into the regenerators 12, and gas in the regenerators 12 can also flow into the air chambers 11.
The number of combustion chambers 13 is one and is fixed to each regenerator 12 and is in communication with each regenerator 12, for example, three regenerators 12, then the combustion chambers 13 have three connection ends, each of which is connected to one regenerator 12, and the gas in the regenerators 12 can enter the combustion chamber 13 and the gas in the combustion chamber 13 can also enter the regenerators 12.
Each plenum 11 is provided with two plenums 21, and the plenums 21 are symmetrically disposed on both sides of the plenum 11 and are respectively connected to a pair of opposite side walls of the plenum 11 and communicate with the space inside the plenum 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 for guiding the gas to be treated into the gas chamber 21 or guiding the treated 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, where 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 raft plates 232 rotatably connected to the outer frame 231, and each raft plate 232 has two states, one is in an open state and the other is in a closed state.
When the raft 232 is in an open state, the gas in the gas chamber 21 can flow in or out through the connecting pipeline 22; when the raft 232 is in the closed state, the gas in the gas chamber 21 does not flow.
The power when the raft 232 rotates is provided by the driving device 24, and the driving device 24 is positioned on the air chamber 21 and outside the air chamber 21, so that the raft 232 can be driven to rotate. The reason why the driving device 24 is disposed outside the air chamber 21 is to avoid the influence of high temperature and impact on the normal operation of the driving device 24, which can make the service life of the driving device 24 longer.
In connection with a specific use, the gas to be treated first flows into the first chamber 21, the raft 232 in the chamber 11 is turned to an open state, the gas in the chamber 21 flows into the chamber 11, and 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 accumulator in the regenerator 12, and is discharged from the air chamber 21 through the air chamber 11.
In the above process, the pressure applied by the air can be dispersed to each raft 232, so that compared with the integral raft structure, the pressure born by the rafts 232 in the structure is smaller, and the reflection speed can be improved. From another angle, it is understood that the rotation radius of the raft 232 is reduced, and under the condition that the wind pressure is unchanged, the moment arm is shortened, and the pressure born by the raft 232 can be effectively reduced.
The driving device 24 can also change the state of the raft 232 in a shorter time, and the reaction speed can be improved to a certain extent. In addition, the two layers of rafts 232 can respectively bear the impact generated by gas during air intake and air exhaust, so that the service life of the rafts 232 can be further prolonged.
Referring to fig. 4 (a) and fig. 4 (B), as a specific embodiment of the multi-valve-group thermal storage high-temperature oxidation system provided in the application, a first inclined plane 233 is added to the top surface of the raft 232, a second inclined plane 234 is added to the bottom surface of the raft 232, and the first inclined plane 233 and the second inclined plane 234 serve to improve the tightness between adjacent rafts 232.
It will be appreciated that, in general, the rafts 232 are rectangular in shape, and so the direction of the gaps between adjacent rafts 232 remains substantially the same as the direction of the air flow within the plenum 21, which results in poor sealing between adjacent rafts 232.
After the first inclined plane 233 and the second inclined plane 234 are added, the gap direction between the adjacent rafts 232 can be changed, and meanwhile, the gap length between the adjacent rafts 232 is increased, so that the tightness between the rafts 232 can be improved.
For example, when the raft 232 is in the closed state, the first inclined surface 233 abuts against the adjacent second inclined surface 234, so that on one hand, the passing length of the gap between the adjacent rafts 232 can be increased, on the other hand, the direction of the gap can be changed, and the two sides are overlapped, so that the tightness between the rafts 232 is better.
Further, sealing strips 235 and sealing grooves 236 are added on the first inclined surface 233 and the second inclined surface 234 respectively, the axis of the sealing strip 235 is parallel to the rotating shaft when the raft 232 rotates, and the axis of the sealing groove 236 is parallel to the rotating shaft when the raft 232 rotates.
When raft 232 is in the closed state, sealing strips 235 can enter sealing grooves 236, so that the complexity of the shape of gaps between adjacent rafts 232 is further improved, and of course, the passing length of the gaps can be increased, so that the tightness between rafts 232 is better.
Referring to fig. 3, as a specific embodiment of the multi-valve group thermal storage high temperature oxidation system provided by the application, 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, wherein the bracket 241 is fixedly mounted on the outer wall of the air chamber 21, and the driver 242 is fixedly mounted on the bracket 241.
The transmission shaft 243 is rotatably connected with the support 241, and is fixedly provided with a driving gear 244 at a first end and connected with the driver 242 at a second end, and a driven gear 245 is installed on the raft 232 and positioned outside the air chamber 21. Adjacent driven gears 245 mesh, and a driving gear 244 meshes with one of the driven gears 245.
In the working process, the driver 242 drives the driven gears 245 to rotate through the transmission shaft 243 and the driving gear 244, so that the raft 232 is opened and closed.
For the driving gear 244 and the driven gear 245, a protective cover may be used to cover them, the protective cover is fixedly installed on the air chamber 21, and one end of the driving shaft 243 extends into the protective cover.
Referring to fig. 2, as an embodiment of the multi-valve group thermal storage high temperature oxidation system provided in the application, in a direction away from the connecting pipe 22, the bottom ends of the first raft layer 23 and the second raft layer 23 are inclined toward a direction approaching the air chamber 11.
In combination with the specific process, in the air intake process, the air flow will first pass through the first raft layer 23, and after the first raft layer 23 is opened, the air flow will impact the second raft layer 23, but because the second raft layer 23 is inclined, the impact force born by the second raft layer is smaller.
In the exhaust process, the air flow will first pass through the second raft layer 23, and when the second raft layer 23 is opened, the air flow will impact the first raft layer 23, but because the first raft layer 23 is inclined, the impact force born by the first raft layer is smaller.
As a specific implementation mode of the multi-valve group heat accumulation high-temperature oxidation system, in the air inlet process, the opening time of the second raft layer 23 lags behind the opening time of the first raft layer 23, so that the gas backflow caused by air pressure can be reduced.
The specific analysis is as follows, in the air intake process, the air flow needs to flow through the second raft layer 23 from right to left, at this time, the first raft layer 23 is opened first, the air pressure on the right side of the second raft layer 23 is increased, at this time, the second raft layer 23 is opened again, and the air flow on the left side of the second raft layer 23 can be prevented from entering the air chamber 21.
Referring to fig. 5 to fig. 7, as a specific embodiment of the multi-valve-group thermal storage high-temperature oxidation system provided by the application, sealing rings 31 are further added to two sides of the outer frame 231, and the sealing rings 31 can be pressed at the junction between the outer frame 231 and the raft 232, so as to further improve the tightness of the raft layer 23.
A guide post 32 is fixed to each outer frame 231, a first end of the guide post 32 is fixed to the sealing ring 31, a second end of the guide post 32 passes through the outer frame 231 and the other sealing ring 31, and the guide post 32 is used for limiting the sealing ring 31 to move according to a set movement track.
When the raft 232 is opened, the two sealing rings 31 can be pushed to move away from each other, and when the raft 232 is closed, the two sealing rings need to move towards each other and be attached to the junction of the outer frame 231 and the raft 232.
The power of the sealing rings 31 toward each other is provided by the springs 33, both ends of the springs 33 are respectively fixed to the adjacent sealing rings 31, and the middle portion thereof passes through the through hole 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.
After the guide pipe 34 is added, the length of the spring 33 can be increased, the service life of the spring 33 can be longer, the thickness of the outer frame 231 can be reduced, and the weight of the outer frame 231 can be reduced.
The embodiments of the present invention are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
