Abstract
Description
Technical Field
[0001] This invention relates to the field of steam utilization technology, and more specifically to a steam preparation apparatus. Background Technology
[0002] In the building materials, metallurgy, chemical, and cement industries, indirect dryers are commonly used to dry materials such as limestone, coal powder, slag, and clay by passing steam through them. To enhance surface evaporation, a certain amount of air (called "carrier gas") needs to be introduced onto the material side. Therefore, after drying, the material produces humid, hot air under slight negative pressure. This humid, hot air carries a large amount of water vapor and thus has a high calorific value. Directly releasing it into the environment would not only result in a significant loss of energy but also have a negative impact on the environment.
[0003] Existing technologies include methods for converting humid air into steam for utilization, such as using steam drying devices for steam conversion. However, the utilization of waste heat from humid air in these methods is difficult, and the cost of steam preparation is high.
[0004] Therefore, existing technologies need further development. Summary of the Invention
[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a steam preparation apparatus to solve the technical problem of high cost in steam preparation in related technologies.
[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: A steam preparation device is provided, comprising: a drive motor, one end of the output shaft of the drive motor having a first connecting end, and the other end of the output shaft of the drive motor having a second connecting end; a compression assembly, internally used to contain the fluid to be recovered, the compression assembly having a compression component connected to the first connecting end, the compression component being used to perform work on the fluid to be recovered; a first outlet pipe connected to the compression assembly to draw out the liquid inside the compression assembly; and a second outlet pipe, one end of the second outlet pipe connected to the compression assembly to draw out the steam inside the compression assembly, the other end of the second outlet pipe being connected to the second connecting end so that the steam drives the second connecting end to rotate.
[0007] Furthermore, the compression assembly includes: a compression chamber, in which a compression component is disposed; an inlet pipe, which communicates with the compression chamber so that the fluid to be recovered enters the compression chamber after passing through the inlet pipe; and an outlet pipe, which communicates with the compression chamber so that the fluid to be recovered in the compression chamber flows out of the outlet pipe.
[0008] Furthermore, the steam preparation device also includes a condensation mechanism connected to the end of the steam outlet pipe away from the compression chamber, so as to cool the fluid to be recovered flowing out of the compression chamber.
[0009] Furthermore, the steam preparation apparatus also includes a separation device connected to a condensation mechanism to introduce the cooled fluid to be recovered into the separation device; the separation device is used to separate the liquid and steam in the fluid to be recovered; the first outlet pipe and the second outlet pipe are respectively connected to the separation device.
[0010] Furthermore, one end of the first outlet pipe is connected to the separation device, and the other end of the first outlet pipe is connected to the condensation mechanism. The condensation mechanism has an evaporation section, and both the steam outlet pipe and the first outlet pipe are connected to the evaporation section so that the heat of the fluid to be recovered in the steam outlet pipe is transferred to the liquid in the first outlet pipe through the evaporation section, thereby causing the liquid to form steam.
[0011] Furthermore, the preparation apparatus also includes a steam outlet pipe, which is connected to a condensation mechanism to draw out the steam inside the condensation mechanism.
[0012] Furthermore, the preparation apparatus also includes a filter element disposed on the first outlet pipe, which is used to filter the liquid in the first outlet pipe.
[0013] Furthermore, the steam preparation device also includes an expansion section impeller, which is connected to the second connecting end to drive the expansion section impeller to rotate through the fluid in the second outlet pipe.
[0014] Furthermore, the steam preparation apparatus also includes an expansion assembly, which has: an expansion chamber connected to a second outlet pipe, wherein an expansion section impeller is rotatably disposed within the expansion chamber; and a gas outlet pipe connected to the expansion chamber so that gas within the expansion chamber is discharged through the gas outlet pipe.
[0015] Furthermore, the compression component is an impeller structure.
[0016] Beneficial effects:
[0017] The steam preparation device of the present invention uses the impeller of the compression section of a centrifugal compressor expander to compress hot and humid air and generate steam in the condensation mechanism. Then, the impeller of the expansion section is used to do work on the non-condensable gas, thereby realizing the full utilization of waste heat and waste pressure.
[0018] Compared with other devices, the steam preparation device of this invention has the advantages of low equipment investment cost, high utilization rate of waste heat from humid air, and outstanding economy and energy saving because the core equipment used in this patent to prepare steam using humid hot air is a centrifugal compressor expander and a condenser.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0023] See Figure 1 According to an embodiment of the present invention, a steam preparation apparatus is provided, comprising: a drive motor 1, one end of the output shaft of the drive motor 1 having a first connecting end, and the other end of the output shaft of the drive motor 1 having a second connecting end; a compression assembly for containing a fluid to be recovered, the compression assembly having a compression component 21 connected to the first connecting end, the compression component 21 being used to perform work on the fluid to be recovered; a first outlet pipe 3 connected to the compression assembly to draw out the liquid inside the compression assembly; and a second outlet pipe 4, one end of the second outlet pipe 4 connected to the compression assembly to draw out the steam inside the compression assembly, the other end of the second outlet pipe 4 being connected to the second connecting end so that the steam drives the second connecting end to rotate.
[0024] With the above configuration, the fluid to be recovered passes through the compression assembly. The compression component 21 performs work on the fluid to be recovered, thereby forming a high-temperature and high-pressure fluid, which is then used to evaporate condensate. The liquid in the fluid to be recovered is led out through the first outlet pipe 3 and then applied. The steam in the fluid to be recovered is led out through the second outlet pipe 4 to the second connection end, so that the steam performs work on the second connection end, thereby assisting the output shaft of the drive motor 1 to rotate, thus reducing the power consumption of the drive motor 1. In this way, by diverting the fluid to be recovered and applying the diverted liquid and gas in a targeted manner, the energy efficiency is improved, and the technical problem of high cost of steam preparation in related technologies is solved.
[0025] Specifically, the hot and humid air generated during the drying process is heated and pressurized by the compression component 21, and then enters the condensation mechanism 5 for condensation. The condensed air-water mixture then enters the separation device 6 for separation.
[0026] Specifically, one compression section impeller and one expansion section impeller are respectively installed on the extended shafts at both ends of a dual-output shaft main motor (i.e., drive motor 1) to form a centrifugal compression expander.
[0027] See Figure 1 In the steam preparation apparatus of this embodiment, the compression assembly includes: a compression chamber 22, a compression component 21 disposed inside the compression chamber 22; a steam inlet pipe 221 connected to the compression chamber 22 so that the fluid to be recovered enters the compression chamber 22 after passing through the steam inlet pipe 221; and a steam outlet pipe 222 connected to the compression chamber 22 so that the fluid to be recovered in the compression chamber 22 flows out of the steam outlet pipe 222.
[0028] In the steam preparation apparatus of this embodiment, see... Figure 1 The steam generation apparatus also includes a condensation mechanism 5, which is connected to the end of the steam outlet pipe 222 away from the compression chamber 22, so as to cool the fluid to be recovered flowing out of the compression chamber 22. In this way, the liquid in the fluid to be recovered can be effectively diverted.
[0029] See Figure 1 In this embodiment of the steam generating apparatus, the steam generating apparatus further includes a separation device 6, which is connected to the condensing mechanism 5 to introduce the cooled fluid to be recovered into the separation device 6; the separation device 6 is used to separate the liquid and steam in the fluid to be recovered; the first outlet pipe 3 and the second outlet pipe 4 are respectively connected to the separation device 6. In this way, by setting the separation device 6, steam and liquid can be effectively diverted to the first outlet pipe 3 and the second outlet pipe 4 respectively.
[0030] In the steam preparation apparatus of this embodiment, see... Figure 1 One end of the first outlet pipe 3 is connected to the separation device 6, and the other end is connected to the condensation mechanism 5. The condensation mechanism 5 has an evaporation section. Both the steam outlet pipe 222 and the first outlet pipe 3 are connected to the evaporation section so that the heat of the fluid to be recovered in the steam outlet pipe 222 is transferred to the liquid in the first outlet pipe 3 through the evaporation section, thereby causing the liquid to form steam. In this way, the separated liquid exchanges heat with the high-temperature and high-pressure fluid to be recovered in the condensation mechanism 5, so that the liquid separated from the fluid to be recovered can be reused, thereby improving the energy utilization rate.
[0031] See Figure 1 In this embodiment of the steam generation apparatus, the apparatus further includes a steam outlet pipe 7, which is connected to the condensation mechanism 5 to draw out the steam within the condensation mechanism 5. In this way, the drawn-out steam can be supplied to other structures to realize energy utilization.
[0032] To achieve higher quality of the liquid separated by separation device 6, see [link to relevant documentation]. Figure 1In the steam preparation apparatus of this embodiment, the preparation apparatus further includes a filter component 8, which is disposed on the first outlet pipe 3 and is used to filter the liquid in the first outlet pipe 3.
[0033] In the steam generating apparatus of this embodiment, the steam generating apparatus further includes an expansion section impeller 9, which is connected to the second connecting end so as to drive the expansion section impeller 9 to rotate through the fluid in the second outlet pipe 4.
[0034] In the steam preparation apparatus of this embodiment, the steam preparation apparatus further includes an expansion assembly, which has an expansion cavity 101 connected to a second outlet pipe 4, and an expansion section impeller 9 rotatably disposed within the expansion cavity 101; and a gas outlet pipe 102 connected to the expansion cavity 101 so that the gas in the expansion cavity 101 is discharged through the gas outlet pipe 102.
[0035] In the steam preparation apparatus of this embodiment, the compression component 21 is an impeller structure.
[0036] The following is in conjunction with the appendix Figure 1 The present invention will be described in detail with reference to specific embodiments.
[0037] An apparatus for generating steam using humid and hot air according to an embodiment of this patent.
[0038] The specific implementation scheme of the steam preparation apparatus of the present invention is as follows:
[0039] The hot and humid air generated during the drying process is heated and pressurized by the compression component 21, and then enters the condensation mechanism 5 for condensation. The condensed air-water mixture enters the separation device 6 for separation. The non-condensable gas separated by the separation device 6 enters the expansion component for expansion and work, reducing the power consumption of the compression component 21.
[0040] The condensate separated by the separation device 6 passes through the filter component 8 to remove impurities and then returns to the condensation mechanism 5. After being heated by high-temperature and humid air, it becomes steam and is used in the drying process itself or other processes.
[0041] The non-condensable gas separated by the separation device 6 still has a certain pressure and is rich in water vapor. If it is directly discharged into the environment, the energy consumption of the non-condensable gas during the heating and pressurization process will be wasted. Therefore, the non-condensable gas enters the separation device 6 to expand and do work to recover the waste heat and waste pressure of the non-condensable gas, effectively reducing the power consumption of the compression component 21.
[0042] The condensate separated by the separation device 6 passes through the filter component 8 to remove impurities and then returns to the condensation mechanism 5. After being heated by high-temperature and humid air, it becomes steam and is used in the drying process itself or other processes.
