[0055] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0056] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0057] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0058] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0059] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0060] In the following description, "connection" includes both a direct connection between the two and an indirect connection between the two through, for example, an adapter board, middleware, etc.

[0061] In the following description, "material", "fuel", "hot gas", "reactant", "air", "hot air" and "product" are only used to illustrate the working principle of the spray reaction device and should not be regarded as part of the spray reaction device.

[0062] like Figures 1 to 11As shown, the spray reaction device in the present application includes: a feeding system 120, a heating system 110, a gas distribution system 140 and a heat exchange system 160; the gas distribution system 140 includes an input end 1401 and an output end 1402; the feeding system 120 and the heating system 110 are both connected to the input end 1401, the feeding system 120 is used to transport the material 400 to the gas distribution system 140, and the heating system 110 is used to transport the hot gas formed by the hot air 300 and the fuel 330 to the gas distribution system 140; one end of the heat exchange system 160 is connected to the output end 1402, and the other end of the heat exchange system 160 is connected to the heating system 110, and the heat exchange system 160 is used to obtain the hot air 300.

[0063] Specifically, the feed system 120 of the present application is connected to the input end 1401 of the gas distribution system 140 via a pipeline, so that the material 400 can be transported from the feed system 120 to the gas distribution system 140. The heating system 110 is connected to the input end 1401 of the gas distribution system 140 via a pipeline, and the heating system 110 can transport hot gas generated by the combustion of fuel 330 to the gas distribution system 140. The gas distribution system 140 is used to react the material 400 and fuel 330 transported to the gas distribution system 140 to produce the desired granular or powdered product 501. The heat exchange system 160 can exchange heat between the reactants generated by the reaction of the material 400 and fuel 330 and the air 300 to produce hot air 300; alternatively, the heat exchange system 160 can exchange heat between the hot gas and the air 300 to produce hot air 300.

[0064] Thus, by delivering the hot air 300 obtained by the heat exchange system 160 to the heating system 110 to participate in the combustion of the fuel 330, the temperature of the resulting hot gas is significantly increased. Furthermore, when the higher-temperature hot gas is delivered to the gas distribution system 140 to react with the material 400, the reaction temperature of the spray reaction device can be effectively increased, significantly enhancing the reaction rate between the material 400 and the hot gas, and further improving the production efficiency and quality of the spray reaction device.

[0065] In addition, since the spray reaction device described in the present application has a relatively high reaction temperature, it can also react with materials 400 that require a relatively high reaction temperature, thereby further improving the scope of application of the spray reaction device.

[0066] In addition, it should be noted that the pipeline connection used in this application can also be other connection methods, as long as it can achieve the transportation of material 400, fuel 330, gas, reactants and products 501. Those skilled in the art can make a choice according to actual needs, and this application does not make any specific restrictions here.

[0067] In one embodiment, the gas distribution system 140 includes a reaction chamber 141, which is used to react hot gas and material 400 to obtain reactants; the heat exchange system 160 is used to exchange heat between the reactants and air 300 to form hot air 300, and to transport the obtained hot air 300 to the heating system 110 to react with the fuel 330 to form hot gas.

[0068] Specifically, if Figures 1 to 11 As shown, the gas distribution system 140 of the present application is provided with a reaction chamber 141. The feeding system 120 can deliver the material 400 to the reaction chamber 141. Thus, when the heating system 110 delivers the hot gas formed by the hot air 300 and the fuel 330 to the reaction chamber 141, the hot gas and the material 400 can react to generate reactants. The reactants can be granular or powdered products.

[0069] Among them, most of the generated reactants are collected by the collecting system 150 to prepare the product 501; another part of the generated reactants can be transported to the heat exchange system 160 to exchange heat with the air 300 entering the heat exchange system 160 to form hot air 300.

[0070] Thus, the present application further increases the temperature of the formed hot gas by transporting a portion of the reactants to the heat exchange system 160 to exchange heat with the air 300 to form hot air 300, and then transporting the hot air 300 to the heating system 110 to participate in the combustion of the fuel 330, thereby further increasing the reaction temperature of the spray reaction device. Moreover, compared to the spray reaction device in the prior art, which has a maximum reaction temperature of only 300°C, the present application can achieve a reaction temperature of 900-1200°C through the above-mentioned configuration, which is much higher than the reaction temperature of the spray reaction device in the prior art. This can achieve a better reaction effect between the material 400 and the hot gas, and thus improve the quality of the product 501 produced by the spray reaction device.

[0071] In addition, the remaining hot gas after being transported to the reaction chamber 141 for reaction in the present application can also be transported to the heat exchange system 160 to perform heat exchange with the air 300 passed through the heat exchange system 160 to form hot air 300; or, the remaining hot gas is transported to the heat exchange system 160 together with another part of the generated reactants to perform heat exchange with the air 300 passed through the heat exchange system 160 to form hot air 300.

[0072] In one embodiment, the spray reaction device further includes a receiving system 150 and a cooling system 170, wherein the receiving system 150 is arranged between the output end 1402 and the heat exchange system 160, and the cooling system 170 is connected to the receiving system 150; the receiving system 150 is used to collect reactants and transport the reactants to the cooling system 170; the cooling system 170 is used to cool the reactants.

[0073] Specifically, if Figures 1 to 11 As shown, one end of the material receiving system 150 of the present application is connected to the input end 1401 by a pipeline, so that the reactants generated after the reaction of the material 400 and the fuel 330 can be transported to the material receiving system 150. The other end of the material receiving system 150 is connected to the cooling system 170 and the heat exchange system 160 by pipelines. Most of the reactants collected by the material receiving system 150 can be transported to the cooling system 170 for cooling and prepared into products 501 for output; another portion of the reactants and hot gas collected by the material receiving system 150 can be transported to the heat exchange system 160 to form hot air 300.

[0074] Therefore, since the reactants generated after the reaction of the material 400 and the fuel 330 still have a relatively high temperature, the present application effectively improves the production efficiency of the spray reaction device through the provision of the material receiving system 150 and the cooling system 170.

[0075] In addition, in order to further improve the cooling efficiency of the cooling system 170 and facilitate the rapid production of the product 501 and the subsequent storage, transportation and processing of the product 501, the cooling system 170 is preferably a liquid cooling system.

[0076] In one embodiment, the material receiving system 150 includes a primary material receiving system 151 and a secondary material receiving system 152 , and both the primary material receiving system 151 and the secondary material receiving system 152 are connected to the output end 1402 ; wherein, the secondary material receiving system 152 is also connected to the heat exchange system 160 .

[0077] Specifically, the collecting system 150 described in the present application is a multi-stage collecting system 150 to effectively collect reactants with higher temperatures, so that after the reactants collected by different collecting systems 150 are transported to the cooling system 170, the cooling efficiency of the reactants can be significantly improved.

[0078] Among them, such as Figure 2 As shown, the material receiving system 150 of the present application preferably adopts a two-stage material receiving system 150, so as to further reduce the production cost of the spray reaction device on the basis of improving the cooling efficiency of the reactants.

[0079] For example, the material receiving system 150 described in the present application includes a primary material receiving system 151 and a secondary material receiving system 152. One end of each of the primary material receiving system 151 and the secondary material receiving system 152 is connected to the output end 1402 by a pipeline, so that the reactants generated after the reaction of the material 400 and the fuel 330 can be transported to the primary material receiving system 151 or the secondary material receiving system 152 for collection. The other ends of each of the primary material receiving system 151 and the secondary material receiving system 152 are connected to the cooling system 170 by a pipeline, so that the reactants collected by the primary material receiving system 151 or the secondary material receiving system 152 can be transported to the cooling system 170 for cooling. Therefore, since the reactants generated after the reaction of material 400 and fuel 330 still have a relatively high temperature, in order to enable the reactants to be collected and cooled more quickly, the present application sets up a two-stage material collection system 150 to collect the reactants with a relatively high temperature, thereby effectively improving the cooling efficiency of the reactants, and then transporting the collected reactants to the cooling system 170, further improving the production efficiency of the spray reaction device, and significantly reducing the production cost of the spray reaction device.

[0080] In addition, the secondary receiving system 152 described in the present application is also connected to the heat exchange system 160 to transport a portion of the reactants to the heat exchange system 160 to perform heat exchange with the air 300 entering the heat exchange system 160 and form hot air 300.

[0081] In addition, the primary receiving system 151 and the secondary receiving system 152 described in the present application may be cyclone separators to better carry reactants with higher temperatures.

[0082] In one embodiment, the heat exchange system 160 includes a primary heat exchange system 161 and a secondary heat exchange system 162 , both of which are connected to the receiving system 150 , and the primary heat exchange system 161 is connected to the secondary heat exchange system 162 .

[0083] Specifically, the heat exchange system 160 described in the present application is a multi-stage heat exchange system 160, so that a portion of the reactants can be transported to the multi-stage heat exchange system 160 for multi-stage heat exchange, thereby effectively increasing the temperature of the hot gas formed by the heat exchange system 160.

[0084] Among them, such as Figure 3 As shown, the heat exchange system 160 of the present application preferably adopts a two-stage heat exchange system 160, so as to further reduce the production cost of the spray reaction device on the basis of increasing the temperature of the hot gas formed by the heat exchange system 160.

[0085] For example, the primary heat exchange system 161 and the secondary heat exchange system 162 described in the present application are both connected to the material receiving system 150 by pipeline, so that a portion of the reactants are transported to the heat exchange system 160 to exchange heat with the air 300 introduced into the heat exchange system 160, thereby forming hot air 300. Therefore, since the reactants generated after the reaction of the material 400 and the fuel 330 still have a relatively high temperature, the present application provides a two-stage heat exchange system 160 to perform multi-stage heat exchange on the reactants with relatively high temperatures, thereby effectively increasing the temperature of the generated hot gas and significantly reducing the production cost of the spray reaction device.

[0086] In addition, when the heat exchange system 160 described in the present application includes a primary heat exchange system 161 and a secondary heat exchange system 162, the temperature of heat exchange in the primary heat exchange system 161 can be made greater than the temperature of heat exchange in the secondary heat exchange system 162, thereby further improving the heat exchange effect of the heat exchange system 160 through the heat exchange temperature difference between the primary heat exchange system 161 and the secondary heat exchange system 162, and significantly improving the quality of the hot gas formed.

[0087] In addition, the temperature of heat exchange in the primary heat exchange system 161 described in the present application may also be lower than the temperature of heat exchange in the secondary heat exchange system 162, as long as there is a difference between the temperature of heat exchange in the primary heat exchange system 161 and the temperature of heat exchange in the secondary heat exchange system 162.

[0088] In one embodiment, the material receiving system 150 includes a primary material receiving system 151 and a secondary material receiving system 152, and the primary material receiving system 151 is connected to the output end 1402; the heat exchange system 160 includes a primary heat exchange system 161 and a secondary heat exchange system 162, and the primary heat exchange system 161 is connected to the secondary heat exchange system 162, and the primary heat exchange system 161 is also connected to the secondary material receiving system 152, and the secondary heat exchange system 162 is also connected to the primary material receiving system 151.

[0089] Specifically, since the temperature of the hot gas formed in the spray reaction device described in the present application is far higher than the temperature of the gas in the spray reaction device in the prior art, for example, the temperature of the hot gas formed in the spray reaction device described in the present application can be close to or exceed 1000°C, the bag filter commonly used in the spray reaction device in the prior art is difficult to be directly used in the spray reaction device described in the present application.

[0090] However, bag filters can achieve low-cost and effective collection of reactants, which has high economic benefits. Figure 4 As shown, the present application sets the first-level material receiving system 151 to be connected to the output end 1402 by pipeline, the first-level heat exchange system 161 to be connected to the second-level material receiving system 152 by pipeline, and the second-level heat exchange system 162 to be connected to the first-level material receiving system 151 by pipeline, so that the spray reaction device can use a bag filter to collect the reactants obtained by the reaction in the reaction chamber 141 described in the present application, thereby effectively reducing the production cost of the product 501, and also making it possible for the hot gas containing the reactants to enter the heat exchange system 160 more conveniently after being output from the reaction chamber 141 to perform heat exchange with the air 300, thereby significantly improving the efficiency of the hot gas formed.

[0091] Moreover, since the primary heat exchange system 161 is connected to the secondary heat exchange system 162 by a pipeline, after the primary receiving system 151 preliminarily collects the reactants obtained by the reaction in the reaction chamber 141, the reactants and hot gases can also pass through the secondary heat exchange system 162 and the primary heat exchange system 161 in sequence for at least two heat exchange and cooling operations, and then the reactants are collected by the secondary receiving system 152 and transported to the cooling system 170 for further cooling, significantly improving the cooling efficiency of the spray reaction device for the reactants. In this application, the primary receiving system 151 is a cyclone separator, and the secondary receiving system 152 is a bag filter.

[0092] In addition, when the temperature of the hot gas formed in the spray reaction device described in the present application is low, the first-level collecting system 151 and the second-level collecting system 152 can also use cyclone separators to collect the reactants. Those skilled in the art can make a choice according to actual needs, and the present application does not make any specific restrictions here.

[0093] In addition, if Figure 6 As shown, compressed air 320 is introduced into the secondary receiving system 152 to further cool the reactants and improve the cooling efficiency of the spray reaction device on the reactants.

[0094] In one embodiment, the spray reaction device further includes a first pipeline 260 and a second pipeline 211 , wherein the first pipeline 260 is arranged between the primary heat exchange system 161 and the secondary heat exchange system 162 , and the second pipeline 211 is arranged between the secondary heat exchange system 162 and the heating system 110 .

[0095] Specifically, if Figure 4 As shown, the spray reaction device described in the present application connects the first heat exchange system 161 and the second heat exchange system 162 by setting the first pipeline 260, and connects the second heat exchange system 162 and the heating system 110 through the second pipeline 211, thereby effectively improving the circulation efficiency of the reactants between the systems, thereby further improving the production efficiency of the product 501.

[0096] In one embodiment, the first pipeline 260 includes a first branch 261 and a second branch 262. The reactants in the primary heat exchange system 161 can be transported to the secondary heat exchange system 162 through the first branch 261, and the reactants in the secondary heat exchange system 162 can be transported to the primary heat exchange system 161 through the second branch 262.

[0097] Specifically, if Figure 5 As shown, the present application connects the primary heat exchange system 161 and the secondary heat exchange system 162 through the first branch 261 and the second branch 262, so that the air 300 can be heat-exchanged with the hot gas with a relatively low temperature in the primary heat exchange system 161, and then enter the secondary heat exchange system 162 for further heat exchange with the hot gas with a relatively high temperature, so that hot air 300 with a higher temperature can be obtained, and then the obtained hot air 300 is transported to the heating system 110 to react with the fuel 330 to form hot gas, which can significantly increase the temperature of the hot gas formed, that is, further increase the reaction temperature of the spray reaction device.

[0098] In one embodiment, the flow rate of the reactants transported from the secondary heat exchange system 162 to the primary heat exchange system 161 is 60 to 70% of the flow rate of the reactants transported from the primary receiving system 151 to the secondary heat exchange system 162; or, the flow rate of the reactants transported from the secondary heat exchange system 162 to the primary heat exchange system 161 is in the range of 500 to 800 kg / h; or, the flow rate of the reactants transported from the secondary heat exchange system 162 to the primary heat exchange system 161 is in the range of 1000 to 1400 / h.

[0099] Specifically, when the heat exchange system 160 described in the present application circulates hot gas, the flow rate of the circulating hot gas cannot be too much. Too much circulating hot gas can easily lead to incomplete combustion, which in turn can easily cause the temperature of the generated hot air 300 to drop, and can also easily cause pollution to the reactants and even produce toxic gases; in addition, the flow rate of the circulating hot gas cannot be too little. Too little circulating hot gas is not conducive to heat recovery and utilization, and can easily cause the temperature of the generated hot air 300 to be low.

[0100] Therefore, it is preferred that the flow rate of the reactants transported from the secondary heat exchange system 162 to the primary heat exchange system 161 is 60 to 70% of the flow rate of the reactants transported from the primary receiving system 151 to the secondary heat exchange system 162; or, the flow rate range of the reactants transported from the secondary heat exchange system 162 to the primary heat exchange system 161 is 500 to 800 kg / h; or, the flow rate range of the reactants transported from the secondary heat exchange system 162 to the primary heat exchange system 161 is 1000 to 1400 / h.

[0101] In one embodiment, the flow rate of the reactants transported from the secondary heat exchange system 162 to the heating system 110 is 30 to 40% of the flow rate of the reactants transported from the primary receiving system 151 to the secondary heat exchange system 162; or, the flow rate of the reactants transported from the secondary heat exchange system 162 to the heating system 110 is 200 to 400 kg / h.

[0102] Specifically, when the heat exchange system 160 described in the present application circulates hot gas, the flow rate of the circulating hot gas cannot be too much. Too much circulating hot gas can easily lead to incomplete combustion, which in turn can easily cause the temperature of the generated hot air 300 to drop, and can also easily cause pollution to the reactants and even produce toxic gases; in addition, the flow rate of the circulating hot gas cannot be too little. Too little circulating hot gas is not conducive to heat recovery and utilization, and can easily cause the temperature of the generated hot air 300 to be low.

[0103] Therefore, it is preferred that the flow rate of the reactants transported from the secondary heat exchange system 162 to the heating system 110 is 30 to 40% of the flow rate of the reactants transported from the primary receiving system 151 to the secondary heat exchange system 162; or, the flow rate of the reactants transported from the secondary heat exchange system 162 to the heating system 110 is 200 to 400 kg / h.

[0104] In one embodiment, the spray reaction device further includes a first exhaust fan 190 , which is connected to the secondary material receiving system 152 .

[0105] Specifically, if Figure 7As shown, the spray reaction device described in the present application further includes a first exhaust fan 190, and the first exhaust fan 190 is connected to the pipeline of the secondary material receiving system 152 to further improve the performance of the spray reaction device described in the present application.

[0106] For example, after the first-level collecting system 151 preliminarily collects the reactants obtained from the reaction in the reaction chamber 141, the reactants and hot gases can be sequentially passed through the second-level heat exchange system 162 and the first-level heat exchange system 161 for at least two heat exchange and cooling operations. At this time, the second-level collecting system 152 can collect the reactants, and the first exhaust fan 190 can discharge the hot gases to avoid the problem of excessive circulating hot gases easily causing the temperature of the generated hot air 300 to drop.

[0107] In one embodiment, the spray reaction device further includes a second exhaust fan 191 , which is connected to the heat exchange system 160 .

[0108] Specifically, if Figure 8 As shown, the spray reaction device described in the present application further includes a second exhaust fan 191, and the second exhaust fan 191 is connected to the heat exchange system 160 pipeline to further improve the performance of the spray reaction device described in the present application.

[0109] For example, the hot gas after heat exchange with the air 300 in the heat exchange system 160 can be discharged by the second exhaust fan 191 to avoid the problem that excessive circulating hot gas may easily cause the temperature of the generated hot air 300 to drop.

[0110] In one embodiment, the heat exchange system 160 includes a primary heat exchange system 161 and a secondary heat exchange system 162, and the primary heat exchange system 161 is connected to the secondary heat exchange system 162; it also includes a circulating fan 180, one end of the circulating fan 180 is connected to the secondary heat exchange system 162, and the other end of the circulating fan 180 is connected to the heating system 110.

[0111] Specifically, if Figure 9 As shown, the present application contains a primary heat exchange system 161 and a secondary heat exchange system 162 in the heat exchange system 160, and the primary heat exchange system 161 and the secondary heat exchange system 162 are connected to each other. By transporting part of the hot gas that has undergone heat exchange in the secondary heat exchange system 162 to the circulating fan 180, and then the circulating fan 180 circulates this part of the hot gas to the heating system 110, the recycling of the hot air 300 is effectively achieved, and the energy consumption of the spray reaction device is significantly reduced.

[0112] In one embodiment, the spray reaction device further includes an atomization system 130 , which is disposed between the feeding system 120 and the input end 1401 ; the atomization system 130 includes an atomizer 131 , which is disposed in the gas distribution system 140 .

[0113] Specifically, if Figure 10 As shown, when the material 400 is a fluid material 400, the present application can atomize the fluid material 400 through the atomizer 131 of the atomization system 130 set in the gas distribution system 140, so that smaller liquids can better react with the hot gas and form reactants.

[0114] In one embodiment, compressed air 320 is introduced into the atomization system 130 ; the atomizer 131 is a dual-fluid nozzle, and the compressed air 320 and the material 400 are atomized by the dual-fluid nozzle.

[0115] Specifically, if Figure 10 As shown, in order to further improve the atomization effect of the spray reaction device, compressed air 320 is introduced into the atomization system 130 of the present application, so that the fluid material 400 atomized by the atomizer 131 is turned into smaller droplets, thereby effectively increasing the contact area between the fluid material 400 and the hot gas, achieving more uniform evaporation and reaction of the fluid material 400 and the hot gas, and thus significantly improving the reaction efficiency of the fluid material 400 and the hot gas, and forming a more uniform and finer granular or powdered product 501 after the fluid material 400 reacts with the hot gas.

[0116] In addition, in order to further improve the atomization effect of the fluid material 400, the atomizer 131 is preferably a dual-fluid nozzle, so that the compressed air 320 and the fluid material 400 can be atomized by the dual-fluid nozzle at the same time, thereby achieving higher reaction efficiency and forming finer granular or powdered products 501.

[0117] In one embodiment, the material 400 includes a liquid feed 401 and purified water 402 , which are alternately delivered to the gas distribution system 140 ; ​​and the fuel 330 is natural gas.

[0118] Specifically, since the fluid material 400 may include larger particulate objects, or the liquid in the fluid material 400 is prone to premature evaporation due to heat when it is close to the gas distribution system 140 (for example, when the fluid material 400 is in the atomizer 131), or deposition occurs due to changes in the concentration of the material 400, etc., the feed pipeline of the feed system 120 may be blocked, seriously affecting the working efficiency of the spray reaction device, and may also cause equipment failure or damage.

[0119] Therefore, if Figure 11 As shown, the present application alternately delivers the feed liquid 401 and the purified water 402 to the gas distribution system 140, so that the purified water 402 can wash the systems and pipelines related to the feed, effectively preventing the occurrence of blockage and accumulation of the material 400, and significantly reducing the frequency of equipment shutdown maintenance.

[0120] Among them, the present application can allow the feed liquid 401 to be passed into the spray reaction device for a short time, and then the purified water 402 to be passed into the spray reaction device for a short time, for example, after the feed liquid 401 is passed into the spray reaction device for a few seconds, the purified water 402 is passed into the spray reaction device for a few seconds; or, the alternating frequency of the two can be reduced, for example, after the feed liquid 401 is passed into the spray reaction device for a few minutes, the purified water 402 is passed into the spray reaction device for a few minutes.

[0121] It should be noted that the feed liquid 401 and the purified water 402 only need to be alternately introduced into the spray reaction device, and the time and flow rate of the two being introduced into the spray reaction device can be the same or different.

[0122] In addition, in order to ensure that the reaction temperature of the spray reaction device does not affect the performance of each system of the spray reaction device, it is preferred that the fuel 330 is natural gas.

[0123] Of course, the fuel 330 in this application may also be made of other materials, and those skilled in the art may make a choice based on actual needs. This application does not impose any specific restrictions here.

[0124] The above embodiments focus on the differences between the various embodiments.

Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention.
