Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, and in particular to a multifunctional greenhouse and water atomization system. Background Technology

[0002] Water atomization is a process that utilizes the principle of high-pressure water cutting and crushing. It uses high-pressure water to impact a high-temperature molten metal stream, rapidly breaking it into small metal droplets and then quickly cooling it. The cooled metal particles and cooling water together form a slurry, which, after filtration and drying, yields metal powder. This powder is used to quickly produce leachate for metal powder, for example, in the process of preparing ferric phosphate.

[0003] During water atomization, a large amount of steam is instantly generated due to the direct contact between the molten metal and high-pressure water. This steam carries metal particles. If the metal particles are removed, this steam is high-purity water vapor and will not affect the environment. In related technologies, this steam is usually treated by using an induced draft fan to guide it into a dust collector, where the dust collector filters and collects the metal particles before the exhaust gas is discharged. However, in this method, the waste heat of the steam cannot be effectively utilized, and the metal particles are also contaminated and cannot be reused; they can only be recycled at scrap prices. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multifunctional heating room and water atomization system, which can effectively utilize waste heat from steam and facilitate the recovery and reuse of metal particles in the steam.

[0005] The solution to the technical problem of this utility model is: A multifunctional greenhouse, comprising: greenhouse body; The main pipeline, used to transport steam, is located on the outside of the main body of the greenhouse; A branch pipe assembly, at least partially located within the main body of the greenhouse, wherein the inlet and outlet ends of the branch pipe assembly are respectively connected to the main pipe and are arranged sequentially along the direction of steam transport of the main pipe; The first drainage structure includes a first drainage pool and a first drainage pipe. The upper end of the first drainage pipe is connected to the branch pipe assembly, and the lower end of the first drainage pipe is disposed facing the opening of the first drainage pool.

[0006] This invention has at least the following beneficial effects: The interior of the greenhouse is used to store materials. Steam flows from the main pipe to the branch pipe assembly and then enters the greenhouse body along the branch pipe assembly, heating the materials inside the greenhouse body and effectively utilizing the waste heat of the steam. Heat exchange occurs within the greenhouse body, forming condensate. Metal particles in the steam flow with the condensate along the first drain pipe to the first drain tank, avoiding contamination of the exhaust gas. After settling and drying in the condensate, the metal particles can be used as raw materials, reducing waste.

[0007] As a further improvement to the above technical solution, the multifunctional greenhouse also includes a second drainage structure. This second drainage structure comprises a second drainage pool and a second drainage pipe. The upper end of the second drainage pipe is connected to the main pipeline, and the lower end of the second drainage pipe faces the opening of the second drainage pool. By providing the second drainage structure, pressure relief can be achieved, and condensate formed in the main pipeline can be drained through the second drainage pipe into the second drainage pool, thereby improving the recovery rate of metal particles in the steam.

[0008] As a further improvement to the above technical solution, the branch pipe assembly includes a first branch pipe, a second branch pipe, and a third branch pipe. The first and second branch pipes respectively pass through the main body of the greenhouse, and the third branch pipe is located on the outside of the main body of the greenhouse. The inlet end of the first branch pipe is connected to the main pipe, the outlet end of the first branch pipe is connected to the inlet end of the third branch pipe, the outlet end of the third branch pipe is connected to the inlet end of the second branch pipe, the outlet end of the second branch pipe is connected to the main pipe, and the upper end of the first drain pipe is connected to the third branch pipe. Steam passes through the first, third, and second branch pipes in sequence. The steam can exchange heat with the interior of the greenhouse body in the first and second branch pipes and form condensate, effectively utilizing the heat of the steam while facilitating the recovery of metal particles.

[0009] As a further improvement to the above technical solution, the inlet end of the main pipeline is inclined upwards towards the outlet end, the first branch pipe is inclined upwards from the inlet end to the outlet end, and the second branch pipe is inclined upwards from the inlet end to the outlet end. The steam flows upwards and uphill during its flow, allowing it to pass smoothly and further reducing the amount of metal particles in the steam flowing towards the outlet end of the main pipeline. This reduces the amount of metal particles in the exhaust gas. The metal particles, along with the condensate, enter the first drainage pipe, which is beneficial for subsequent recycling and improves the metal recovery rate.

[0010] As a further improvement to the above technical solution, the first branch pipe and the second branch pipe are each provided with a grid pipe, which is located inside the main body of the greenhouse. Steam flows dispersedly within the grid pipe, increasing the heat dissipation area of ​​the steam and improving the utilization efficiency of waste heat from the steam.

[0011] As a further improvement to the above technical solution, a drainage trough is provided inside the main body of the greenhouse, and the drainage trough is connected to the first drainage pool. The drainage trough inside the main body of the greenhouse is used to collect condensate generated inside the main body of the greenhouse, which can keep the main body of the greenhouse dry and facilitate the recycling of condensate generated inside the main body of the greenhouse.

[0012] As a further improvement to the above technical solution, the multifunctional greenhouse also includes a first valve and a second valve. The first valve is located at the inlet end of the branch pipe assembly, and the second valve is located at the outlet end of the branch pipe assembly. The first and second valves isolate the main pipe from the branch pipe assembly, facilitating gas shut-off maintenance of the greenhouse structure.

[0013] As a further improvement to the above technical solution, the first valve and the second valve are respectively located on the outside of the main body of the greenhouse. This arrangement facilitates subsequent maintenance and use of the first and second valves.

[0014] As a further improvement to the above technical solution, the multifunctional greenhouse also includes a main valve, which is located on the main pipeline between the inlet and outlet ends of the branch pipe assembly. The flow direction of steam can be controlled by using the main valve, the first valve, and the second valve. When using steam to heat the main body of the greenhouse, closing the main valve allows all steam to pass through the branch pipe assembly, thereby improving the utilization rate of waste heat. When it is necessary to shut down the greenhouse for maintenance, closing the second valve and the first valve and opening the main valve allows steam to pass directly through the main pipeline, ensuring smooth steam discharge.

[0015] Secondly, a water atomization system is proposed, the water atomization system including a sedimentation tank, a water atomization device, and a multifunctional greenhouse as described in any one of the technical solutions in the first aspect, the sedimentation tank having a supernatant outlet, the inlet end of the water atomization device being connected to the supernatant outlet, the water atomization device being used to output steam and having a steam outlet, the steam outlet being connected to the inlet end of the main pipeline, and the first condensate tank being connected to the sedimentation tank.

[0016] Because it is equipped with a multi-functional greenhouse, it can effectively utilize the waste heat of steam generated by the water atomization device and realize the recovery and reuse of metal particles in the steam. The condensate formed by the steam can also flow back to the sedimentation tank for recycling. Attached Figure Description

[0024] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0025] Reference Figure 1 and Figure 2 Firstly, this utility model provides a multifunctional greenhouse that can effectively utilize steam heat energy and effectively recover metal particles in the steam. It can be applied to systems with excess steam exhaust gas for comprehensive recovery and utilization. It is particularly suitable for a water atomization system, such as a pretreatment water atomization system for preparing iron phosphate materials.

[0026] The multi-functional greenhouse includes a main body 100, a main pipe 200, a branch pipe assembly 300, and a first drainage structure 400. The main pipe 200 is used to transport steam, and its inlet end is connected to a system providing steam exhaust gas. The main pipe 200 is located outside the main body 100. The branch pipe assembly 300 is at least partially located inside the main body 100. Its inlet and outlet ends are respectively connected to the main pipe 200 and arranged sequentially along the direction of steam transport in the main pipe 200. The first drainage structure 400 includes a first drainage tank 420 and a first drainage pipe 410. The upper end of the first drainage pipe 410 is connected to the branch pipe assembly 300, and the lower end of the first drainage pipe 410 is open towards the first drainage tank 420.

[0027] In use, refractory materials or raw materials are placed inside the main body 100 of the heating chamber. Steam flows from the main pipe 200 to the branch pipe assembly 300 and enters the main body 100 of the heating chamber along the branch pipe assembly 300. The steam heats the materials inside the main body 100 of the heating chamber and achieves heat exchange within the main body 100 of the heating chamber, and the steam is converted into condensate.

[0028] After steam condenses, the condensate flows downwards through the first drain pipe 410 to the first drain tank 420. The metal particles originally mixed in the steam also flow into the first drain tank 420 with the condensate. Understandably, if the steam is directly recycled through a dust removal system to recover the metal particles, the particles are easily contaminated, and contaminated metal particles can only be recycled at scrap prices. In this embodiment, however, the metal particles are recovered through the condensate, allowing them to be used as raw materials after drying.

[0029] In addition, the first drain pipe 410 can also relieve pressure on the branch pipe assembly 300.

[0030] In some embodiments, the main body of the greenhouse 100 is based on a regular warehouse and has the functions of storage and transfer. Raw materials and refractory materials are stored in the main body of the greenhouse 100. Since the electric furnace melting process requires high moisture content of the materials, natural air drying is difficult to meet the usage requirements. The waste heat of steam can provide the main body of the greenhouse 100 with an ambient temperature of 40 to 60 degrees Celsius, which is sufficient for preheating and baking these materials. The baking of the materials can be continuous or discontinuous, and the baking heating time is set according to actual needs.

[0031] In some embodiments, the multifunctional greenhouse further includes a second drainage structure 500, which includes a second drainage pool 520 and a second drainage pipe 510. The upper end of the second drainage pipe 510 is connected to the main pipe 200, and the lower end of the second drainage pipe 510 is opened towards the second drainage pool 520. By providing the second drainage structure 500, pressure relief can be achieved, and condensate returning to the main pipe 200 can be drained, allowing the condensate in the main pipe 200 to be discharged from the second drainage pipe 510 into the second drainage pool 520, so as to facilitate the recovery of metal particles in the steam.

[0032] In some embodiments, the second drainage structure 500 has multiple second drainage pipes 510, which are arranged along the extension direction of the main pipeline 200, and can drain and depressurize multiple locations of the main pipeline 200.

[0033] In some embodiments, the branch pipe assembly 300 includes a first branch pipe 310, a second branch pipe 320, and a third branch pipe 330. The first branch pipe 310 and the second branch pipe 320 are respectively installed in the main body 100 of the greenhouse, with both ends of the first branch pipe 310 and the second branch pipe 320 extending to the outside of the main body 100 of the greenhouse. The third branch pipe 330 is located on the outside of the main body 100 of the greenhouse. The inlet end of the first branch pipe 310 is connected to the main pipe 200, and the outlet end of the first branch pipe 310 is connected to the inlet end of the third branch pipe 330. The outlet end of the third branch pipe 330 is connected to the inlet end of the second branch pipe 320, and the outlet end of the second branch pipe 320 is connected to the main pipe 200. The upper end of the first drain pipe 410 is connected to the third branch pipe 330.

[0034] It is understandable that the steam supplied from the main pipe 200 enters the branch pipe assembly 300 and passes through the first branch pipe 310, the third branch pipe 330, and the second branch pipe 320 in sequence. The steam exchanges heat with the interior of the greenhouse body 100 in the first branch pipe 310 and the second branch pipe 320 and forms condensate. The arrangement of the first branch pipe 310, the second branch pipe 320, and the third branch pipe 330 forms a loop structure on the side of the main pipe 200, which can increase the path length of steam entering the greenhouse body 100 and effectively utilize the heat of the steam.

[0035] In the embodiment where the first hydrophobic structure 400 and the second hydrophobic structure 500 are provided, the condensate in the first branch pipe 310 and the second branch pipe 320 can flow back to the main pipe 200 and be discharged to the second hydrophobic pool 520 through the second hydrophobic pipe 510, or it can flow to the third branch pipe 330 and be discharged to the first hydrophobic pool 420 through the first hydrophobic pipe 410.

[0036] The third branch pipe 330, which is used to connect the first drain pipe 410, is located outside the main body 100 of the greenhouse, which is more conducive to the formation and discharge of condensate.

[0037] In some embodiments, the first hydrophobic structure 400 further includes a first hydrophobic valve disposed on the first hydrophobic pipe 410 for opening or closing the first hydrophobic pipe 410 to promptly relieve pressure and discharge condensate. In some instances, the second hydrophobic structure 500 further includes a second hydrophobic valve disposed on the second hydrophobic pipe 510 for opening or closing the second hydrophobic pipe 510 to promptly relieve pressure and discharge condensate.

[0038] Because the first drain structure 400 and the second drain structure 500 are used together, when one of the first drain valve or the second drain valve fails, the other drain valve can be used normally to relieve pressure.

[0039] It is understandable that both the first and second drain valves are located on the outside of the main body 100 of the greenhouse, which does not affect the maintenance and use of the first and second drain valves.

[0040] In some embodiments, the inlet end of the main pipe 200 is inclined upwards towards the outlet end, the first branch pipe 310 is inclined upwards from the inlet end to the outlet end, and the second branch pipe 320 is inclined upwards from the inlet end to the outlet end. This configuration allows the steam to flow in an upward, sloping manner, ensuring smooth passage and further reducing the amount of metal particles in the steam flowing towards the outlet end of the main pipe 200. This reduces the amount of metal particles in the exhaust gas. The metal particles, along with the condensate, enter the first drain pipe 410 or the second drain pipe 510 and deposit in the first drain tank 420 or the second drain tank 520, which is beneficial for subsequent recycling and improves the metal recovery rate.

[0041] It is understood that the slope of the main pipe 200, the first branch pipe 310, and the second branch pipe 320 can be adjusted according to the actual situation. In some embodiments, the slope of the main pipe 200 is greater than or equal to 1:10, and the slope of the first branch pipe 310 and the second branch pipe 320 is greater than or equal to 1:20.

[0042] In some embodiments, the first branch pipe 310 and the second branch pipe 320 are respectively provided with a grid pipe 340, which is located inside the main body 100 of the greenhouse. When steam flows along the first branch pipe 310 or the second branch pipe in the main body 100 of the greenhouse, it is dispersed through the grid pipe 340. The steam in the first branch pipe 310 and the second branch pipe 320 enters each branch of the grid pipe 340, increasing the heat dissipation area of ​​the steam and allowing it to be fully disturbed by the grid pipe 340. This makes the utilization of steam heat more complete, preheating and baking the materials inside the main body 100 of the greenhouse, which helps to maintain a stable temperature inside the main body 100 of the greenhouse.

[0043] In some embodiments, the grid pipes 340 are placed horizontally, which allows the steam to heat the material baking surface of the greenhouse body 100 more evenly.

[0044] In some embodiments, the grid pipe 340 includes four branch pipes, which extend along the length of the main body 100 of the greenhouse and are arranged parallel to each other along the width of the main body 100 of the greenhouse. Two adjacent branch pipes are connected by two or three pipes.

[0045] In some embodiments, a drainage channel 110 is provided inside the greenhouse body 100, and the drainage channel 110 is connected to the first drainage pool 420. The drainage channel 110 inside the greenhouse body 100 is used to collect condensate generated inside the greenhouse body 100 to keep the greenhouse body 100 dry.

[0046] In some embodiments, the drainage trough 110 and the first drainage pool 420 form a T-shaped structure. The drainage trough 110 extends along the width direction of the greenhouse body 100. The first drainage pool 420 and the drainage trough 110 are perpendicular to each other. One end of the first drainage pool 420 extends into the greenhouse body 100 and communicates with the middle of the drainage trough 110. The other end extends to the outside of the greenhouse body 100 and communicates with the external sedimentation tank.

[0047] In some embodiments, the multifunctional greenhouse further includes a first valve 350 and a second valve 360, wherein the first valve 350 is disposed at the inlet end of the branch pipe assembly 300, and the second valve 360 ​​is disposed at the outlet end of the branch pipe assembly 300. Specifically, the first valve 350 is installed at the inlet end of the first branch pipe 310, and the second valve 360 ​​is installed at the outlet end of the second branch pipe 320.

[0048] The installation of a first valve 350 and a second valve 360 ​​facilitates gas outage maintenance of the main heating chamber 100. When maintenance is required, the second valve 360 ​​is closed first, followed by the first valve 350. Steam cannot enter the branch pipe assembly 300 and can only flow along the main pipe 200. After maintenance is completed, the first valve 350 is opened first, followed by the second valve 360, restoring the steam's path into the main heating chamber 100. The steam then flows along the branch pipe assembly 300 through the main heating chamber 100, raising its temperature and effectively utilizing the steam's heat.

[0049] In the embodiment where the second hydrophobic structure 500 is provided, since the main pipe 200 is connected to the second hydrophobic structure 500, the steam flowing along the main pipe 200 forms condensate in the main pipe 200, which can be discharged to the second hydrophobic pool 520 through the second hydrophobic pipe 510 so that the metal particles in the steam can be recovered and reused.

[0050] In some embodiments, the first valve 350 and the second valve 360 ​​are both located on the outside of the main body 100 of the heating chamber, which makes it more convenient to maintain and use the first valve 350 and the second valve 360 ​​in the future.

[0051] In some embodiments, the multi-functional greenhouse also includes a main valve 210, which is disposed on the main pipe 200 and located between the inlet and outlet ends of the branch pipe assembly 300. The flow direction of steam can be controlled by using the main valve 210, the first valve 350, and the second valve 360.

[0052] When steam is used to heat the main body of the heating chamber 100, closing the main valve 210 cuts off the direct flow of steam from the inlet to the outlet of the main pipe 200. All steam then enters the main body of the heating chamber 100 via the branch pipe assembly 300, improving the utilization rate of steam heat. When the heating chamber 100 needs to be shut down for maintenance, closing the second valve 360 ​​and the first valve 350 and opening the main valve 210 allows direct connection between the inlet and outlet of the main pipe 200, ensuring smooth steam flow to the dust removal system for treating exhaust gas and guaranteeing the continuity of operation of upstream and downstream equipment.

[0053] In some embodiments, the main valve 210, the first valve 350, the second valve 360, and the steam trap are all electrically controlled butterfly valves.

[0054] In some embodiments, the main body 100 of the greenhouse is provided with an insulation layer, and a sealing structure is provided at the location where the first branch pipe 310 passes through the main body 100 of the greenhouse and at the location where the second branch pipe 320 passes through the main body 100 of the greenhouse, so as to ensure the heat insulation performance of the main body 100 of the greenhouse and improve the heating efficiency of the main body 100 of the greenhouse.

[0055] In some embodiments, the main body 100 of the heating chamber can be provided with multiple compartments 120, each used for heating different materials. In some embodiments, the main body 100 of the heating chamber has four compartments 120, corresponding to four different materials: raw materials, auxiliary materials, refractory bricks, and sprue gates. When applied to the process of preparing ferric phosphate, it can achieve residual heat preservation of nickel-iron alloy raw materials, preventing the hazards of wet materials; it can also achieve preheating and heat preservation of auxiliary materials, extending the storage time of easily hygroscopic auxiliary materials such as lime; and it can also achieve preheating and heat preservation of important refractory materials, reducing the probability of clogging accidents during atomization.

[0056] In some embodiments, the multifunctional greenhouse also includes a feeding assembly, which includes a flatcar 130 and a track. Each compartment 120 has openings at both ends, and the track passes through the compartment 120. The flatcar 130 can move in and out of the compartment 120 along the track. Materials are placed on the flatcar 130 to facilitate the movement of materials in and out of the greenhouse body 100.

[0057] In some embodiments, when the flatcar 130 enters the bin 120, the grid pipe 340 is suspended above the flatcar 130, and the grid pipe 340 containing steam can uniformly heat the material inside the flatcar 130.

[0058] Secondly, this utility model embodiment proposes a water atomization system, which includes a sedimentation tank, a water atomization device, and a multi-functional greenhouse as described in any embodiment of the first aspect. The sedimentation tank has a multi-stage sedimentation function, effectively separating the supernatant from the sediment. It is equipped with a supernatant outlet connected to the inlet of the water atomization device. After the supernatant enters the water atomization device, it continuously generates steam. The water atomization device is equipped with a steam outlet connected to the inlet of the main pipe 200. The steam output from the water atomization device enters the multi-functional greenhouse through the inlet of the main pipe 200, achieving a heating effect on the greenhouse body 100 and forming condensate containing metal particles. The first drainage tank 420 in the multi-functional greenhouse is connected to the sedimentation tank, forming a water circulation system. Metal particles in the condensate are deposited, and the condensate can also be recycled, making it economical and environmentally friendly.

[0059] In some embodiments, the water atomizing device is a continuous water atomizing device. When using a continuous water atomizing device, an external steam source is not required, as the steam generated by the water atomizing device can be completely self-sufficient to preheat the materials inside the main body 100 of the greenhouse. If a non-continuous water atomizing device is used, the amount of steam may be insufficient to preheat the materials inside the main body 100 of the greenhouse, and an external steam source needs to be introduced.

[0060] In the embodiment where a drainage trough 110 is provided inside the main body 100 of the greenhouse, the water evaporated inside the main body 100 of the greenhouse can be discharged into the first drainage pool 420 through the drainage trough 110 and enter the sedimentation pool for recycling.

[0061] In this embodiment, the working principle of the water atomization system with a multi-functional greenhouse is as follows: the supernatant from the sedimentation tank enters the water atomization device to form steam, which then enters the multi-functional greenhouse through the main pipe 200. The main valve 210 is closed, and the first valve 350 and the second valve 360 ​​are opened. The steam enters the greenhouse body 100 through the branch pipe assembly 300, and sequentially passes through the first branch pipe 310, the third branch pipe 330, and the second branch pipe 320. The steam undergoes heat exchange in the greenhouse body 100 and forms condensate, which provides heat energy to the greenhouse body 100, heating the materials within and achieving efficient heat utilization. The condensate is discharged to the first condensate tank 420 through the first drain pipe 410 or to the second condensate tank 520 through the second drain pipe 510, ultimately flowing to the sedimentation tank for recycling. Metal particles are discharged with the condensate and settle in the sedimentation tank; the resulting metal particles can be used as raw materials after drying.

[0062] When maintenance is required on the main structure 100 of the greenhouse, the second valve 360 ​​and the first valve 350 are closed sequentially, and the main valve 210 is opened. Steam enters the main pipe 200, where condensate forms and is discharged through the second drain pipe 510 to the second drain tank 520, ultimately flowing into the sedimentation tank for recycling. Metal particles are discharged with the condensate and settle in the sedimentation tank. The resulting metal particles can be used as raw materials after drying.

[0063] This embodiment utilizes the waste heat of the large amount of steam generated during water atomization to bake refractory materials and raw materials. At the same time, the metal particles can be recovered through the condensate formed by steam heat exchange. The metal particles are collected by settling in a sedimentation tank, reducing the loss of metal particles carried in the steam. The condensate can also be recycled in the sedimentation tank.

[0064] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
