Description

Technical Field

[0001] This utility model relates to the technical field of steam filtration system structure, specifically to a steam filtration system structure resistant to high temperature and high pressure. Background Technology

[0002] In industrial production, steam, as an important heat energy carrier and power source, is widely used in chemical, food, pharmaceutical, and power industries. However, during the generation, transmission, and use of steam, impurities such as rust, scale, metal particles, grease, and microorganisms can easily become mixed in due to poor boiler feedwater quality, pipe corrosion, and valve seal wear. Therefore, it is necessary to utilize a steam filtration system to filter the steam and remove impurities, thus preventing the steam from containing contaminants.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology: In typical steam filtration systems, the high temperature and pressure of steam during filtration can cause the filter components to deform due to excessive pressure, leading to damage to the parts. Furthermore, high steam temperatures can cause the parts to melt and age, which in turn affects the filtration effect. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature and high-pressure resistant steam filtration system structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature and high-pressure resistant steam filtration system structure, comprising a cylindrical body, with legs fixedly connected to the bottom of the cylindrical body around its perimeter, an air inlet pipe installed at the top of the cylindrical body, a first valve installed at the top of the air inlet pipe, a spiral conveying pipe installed at the top of the first valve, an inspection door hinged to the upper and middle parts of one end of the outer side of the cylindrical body, a first filter assembly and a second filter assembly arranged sequentially from top to bottom on the inner sidewall of the cylindrical body, an air outlet pipe installed at the center of the bottom of the cylindrical body, a second valve installed at the bottom of the air outlet pipe, and an exhaust pipe installed at the bottom of the second valve. The first filter assembly includes a first support frame fixedly connected to the inner sidewall of the cylindrical body, a first spring evenly fixedly connected to the top of the first support frame, a first limiting rod vertically penetrating the inner side of the first spring, the bottom of the first limiting rod vertically penetrating the top of the first support frame and connected to a first fixing block, a first frame fixedly connected to the top of the first spring and the first limiting rod, and a filter screen installed on the inner side of the first frame.

[0006] The second filter assembly includes a second support frame fixedly connected to the inner wall of the cylinder. A second spring is uniformly fixedly connected to the top of the second support frame. A second limiting rod is vertically installed through the inner side of the second spring. The bottom of the second limiting rod is vertically connected through the top of the second support frame and connected to the second fixing block. A second frame is fixedly connected to the top of the second spring and the second limiting rod. A filter membrane is installed on the inner side of the second frame.

[0007] The beneficial effects of this invention are as follows: the spiral conveying pipe increases the resistance of steam during the conveying process, thereby reducing the steam pressure to a certain extent. The steam is then diverted through the inlet pipe, preventing filtration in localized areas of the filter screen. Furthermore, the elastic deformation of the first and second springs buffers the filter screen and membrane, preventing deformation or damage, thus improving the high-pressure resistance during steam filtration. Simultaneously, the use of a sintered metal mesh as the filter screen and a nano-composite ceramic membrane as the membrane ensures a stable structure and filtration performance during the filtration of high-temperature steam, effectively preventing damage to the filter screen and membrane, increasing service life, and effectively saving costs.

[0008] To prevent steam leakage: Further, the inspection door is equipped with sealing gaskets around its perimeter.

[0009] By adopting the above technical solution, staff can open the inspection door to perform corresponding maintenance and cleaning work on the filter screen and filter membrane. After closing the inspection door, the sealing gasket can be used to increase the airtightness and prevent steam leakage.

[0010] To ensure the first filter component can withstand high temperature and high pressure: Further configuration: the first spring and the first frame form an elastic structure, and the top of the first support frame is uniformly provided with first slots that are consistent with the external dimensions of the first limiting rod, and the filter screen is a sintered metal mesh.

[0011] By adopting the above technical solution, the first spring undergoes elastic deformation after the high-temperature and high-pressure steam passes through the filter screen, causing the first limiting rod to slide within the first slot, thereby buffering the high-pressure steam and preventing component deformation. At the same time, using a sintered metal mesh as the filter screen effectively prevents damage to the filter screen caused by high-temperature steam, thus extending the service life of the components and reducing cost.

[0012] To ensure the second filter component can withstand high temperature and high pressure: Further configuration: the second spring and the second frame form an elastic structure, and the top of the second support frame is uniformly provided with second slots that are consistent with the external dimensions of the second limiting rod, and the filter membrane is a nano-composite ceramic membrane.

[0013] By adopting the above technical solution, the high-temperature and high-pressure steam will cause the second spring to undergo elastic deformation after passing through the filter membrane, thereby causing the first limiting rod to slide in the second slot, thus buffering the high-pressure steam and preventing the parts from deforming. At the same time, using a nano-composite ceramic membrane as the filter membrane can effectively prevent the high-temperature steam from damaging the filter membrane, thereby improving the service life of the parts and reducing cost consumption.

[0014] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0018] Please see Figures 1 to 4A high-temperature and high-pressure resistant steam filtration system structure includes a cylinder 1, with support legs 2 fixedly connected to the bottom of the cylinder 1, an air inlet pipe 3 installed at the top of the cylinder 1, a first valve 4 installed at the top of the air inlet pipe 3, a spiral conveying pipe 5 installed at the top of the first valve 4, an inspection door 6 hinged to the upper and middle parts of one end of the outer side of the cylinder 1, a first filter assembly 7 and a second filter assembly 8 arranged sequentially from top to bottom on the inner side wall of the cylinder 1, an air outlet pipe 9 installed at the center of the bottom of the cylinder 1, a second valve 10 installed at the bottom of the air outlet pipe 9, and an exhaust pipe 11 installed at the bottom of the second valve 10.

[0019] The first filter assembly 7 includes a first support frame 701 fixedly connected to the inner wall of the cylinder 1. A first spring 702 is evenly fixedly connected to the top of the first support frame 701. A first limiting rod 703 is vertically installed through the inner side of the first spring 702. The bottom of the first limiting rod 703 is vertically connected through the top of the first support frame 701 and connected to the first fixing block 704. A first frame 705 is fixedly connected to the top of the first spring 702 and the first limiting rod 703. A filter screen 706 is installed on the inner side of the first frame 705.

[0020] The second filter assembly 8 includes a second support frame 801 fixedly connected to the inner wall of the cylinder 1. A second spring 802 is evenly fixedly connected to the top of the second support frame 801. A second limiting rod 803 is vertically installed through the inner side of the second spring 802. The bottom of the second limiting rod 803 is vertically connected through the top of the second support frame 801 and connected to the second fixing block 804. A second frame 805 is fixedly connected to the top of the second spring 802 and the second limiting rod 803. A filter membrane 806 is installed inside the second frame 805.

[0021] In this embodiment, as Figure 1 As shown, sealing gaskets are installed around the inspection door 6.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the first spring 702 and the first frame 705 form an elastic structure, and the top of the first support frame 701 is uniformly provided with first slots that are consistent with the external dimensions of the first limiting rod 703, and the filter screen 706 is a sintered metal mesh.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the second spring 802 and the second frame 805 form an elastic structure, and the top of the second support frame 801 is uniformly provided with second slots that are consistent with the external dimensions of the second limiting rod 803, and the filter membrane 806 is a nanocomposite ceramic membrane.

[0024] The structure and working process of this high-temperature and high-pressure resistant steam filtration system are as follows: First, the first valve 4 is opened, and steam enters through the spiral conveying pipe 5. The spiral conveying pipe 5 increases the resistance during steam transport, thus reducing the pressure of the high-pressure steam to some extent. Then, the steam is diverted through the air inlet pipe 3, allowing the steam to be dispersed for filtration, avoiding localized filtration on the filter screen 706 and increasing the burden on the filter screen 706. During the filtration process of the filter screen 706, the first spring 702 undergoes elastic deformation, causing the first limiting rod 703 to slide within the first slot. This causes the first frame 705 to move the filter screen 706 vertically, thus buffering the high-pressure steam. The first fixing block 704 prevents the first frame 705 from moving. If the filter screen 706 falls off, the steam will be filtered again by the filter membrane 806. During the filtration process, the second spring 802 will undergo elastic deformation, causing the second limit rod 803 to slide in the second slot. This causes the second frame 805 to move the filter membrane 806 vertically, thus buffering the high-pressure steam. The second fixing block 804 can prevent the second frame 805 from falling off. At this time, the steam filtration work is completed. Then, open the second valve 10 to allow the steam to be discharged through the exhaust pipe 9 and the exhaust pipe 11. The staff can open the inspection door 6 to inspect and clean the filter screen 706 and the filter membrane 806.
