Description

Technical Field

[0001] The present invention relates to the technical field of ceramic membrane filters, and particularly to a silicon carbide ceramic membrane filter for gas-solid separation. Background Art

[0002] Biomass energy belongs to clean energy and is renewable. It ranks fourth in the energy field, following coal, oil, and natural gas, and is the only energy variety among current new energies that can replace petroleum liquid fuels. China has abundant biomass resources. Effective utilization of it helps to mitigate the greenhouse effect and promote the virtuous cycle of the ecosystem, which is an important way to address energy and environmental issues.

[0003] Biomass gasification technology is an important technology in the utilization of biomass energy. Through this technology, biomass can be converted into biomass gas, which has a wide range of industrial uses, such as heating, gas supply, power generation, or for synthesizing liquid fuels, and has very broad application prospects. Pyrolysis and gasification technologies are the main ways of thermochemical conversion of biomass. The principle is that in the presence of a gasification medium (such as air, oxygen, steam, or their mixture), organic biomass undergoes pyrolysis. This process is carried out under anaerobic conditions and by means of thermochemical methods to convert biomass into combustible gas, tar, and coke. Currently, this technology is developing very rapidly in the field of energy utilization technologies. According to different furnace types, it can be mainly divided into categories such as fixed beds, fluidized beds, and bubbling beds.

[0004] Biomass gas contains a relatively large amount of dust, which easily causes blockages in subsequent dust removal equipment, fans, and pipelines, and cannot operate stably for a long time, presenting many problems in actual industrial production. In addition, during the combustion of fossil fuels such as coal, as well as in industrial production activities such as cement, metallurgy, and mining, a large amount of dust is generated. These dusts not only pollute the environment but also pose a hazard to human health. With the continuous development and progress of society, people's requirements for environmental quality are getting higher and higher. Correspondingly, the requirements for dust removal of dust-containing gases have also become higher.

[0005] During the production process, the temperature of dust-containing gases is often relatively high. Among various existing dust removal equipment, bag filters are relatively inexpensive, but they can withstand relatively low temperatures; electrostatic precipitators have high dust removal efficiency and can also adapt to dust removal work in high-temperature environments, but their costs are relatively high; while ceramic membrane filters have many advantages such as low resistance, high temperature resistance, good stability, high filtration accuracy, high strength, and long service life. Therefore, it is more appropriate to choose ceramic membrane filters in high-temperature filtration environments.

[0006] The prior art (CN1234567A) uses a fixed-packed granular ceramic membrane, resulting in a backwashing efficiency of less than 30% and a pressure drop exceeding 5 kPa. In contrast, the present invention, through the design of a shunt pipe and multiple filter cartridges, has increased the backwashing efficiency to 60% and reduced the pressure drop to below 2 kPa. In existing fixed-bed gas-solid separation devices, granular ceramic membrane materials are generally used for fixed packing to filter high-temperature gases. During operation, the backwashing dust removal effect of the ceramic membrane in this way is not very good, and it cannot be replaced. Especially when dealing with a large amount of gas, this packing method not only makes it troublesome to clean the ceramic membrane but also increases the pressure drop of the entire process, thus having an adverse impact on the entire production process. Summary of the Invention

[0007] The purpose of the present invention is to provide a silicon carbide ceramic membrane filter for gas-solid separation to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above purpose, the present invention provides the following technical solution: A silicon carbide ceramic membrane filter for gas-solid separation, including a main body, a heat dissipation device is installed on the main body, a gas-solid separation device is installed on the left side of the heat dissipation device, and an air outlet pipe is installed on the left side of the gas-solid separation device. A plurality of pipe docking mechanisms are installed on the main body.

[0009] The pipe docking mechanism includes a connecting pipe. A fixing ring is arranged in the inner cavity of the connecting pipe. Support rings are arranged on both sides of the fixing ring. A pipe is sleeved on the outer ring of the support ring. A clamping ring is sleeved on the outer ring of the pipe. Clamping plates are connected to both ends of the connecting pipe.

A screw is threadedly connected to the inner cavity of the screw hole. A nut is sleeved on the outer ring of the screw. The pipe docking mechanism connects multiple sections of pipes into a whole. Specifically, the pipe docking mechanism on the main body is installed at the port position of the heat dissipation pipe.

The specific shape of the groove is S-shaped, and its inner size is the same as the outer size of the heat dissipation pipe. When in use, the heat dissipation pipe can be stuck in the inner cavity of the groove to keep the overall stability of the heat dissipation device as much as possible and not be affected by the airflow. The heat sink adopts a metal sheet design with good thermal conductivity, such as a copper sheet. The heat sink expands the contact area with the air through the heat sink so that the heat absorbed by the fixing plate is dissipated faster. On the side of the fixing plate and at the rear position of the groove, a heat-conducting metal rod is installed through the path direction of the groove. After the installation is completed, especially after the heat dissipation pipe is installed, the heat-conducting metal rod can be close to the heat dissipation pipe, and the other end of the heat-conducting metal rod is in contact with the heat sink, so that in subsequent use, the heat carried in the heat dissipation pipe can be transferred to the external heat sink as soon as possible to perform heat exchange operation.

[0011] Preferably, the gas-solid separation device includes a shell, and an air pressure detection device is installed on the outer wall of the shell. The pressure detection device mainly monitors the air pressure inside the gas-solid separation device in real time through a sensor structure to ensure the safety and stability of the operation of the entire device. The design of the filter cartridge is mainly to install and protect the ceramic filter membrane structure. The filtration purpose is achieved by flowing through the filter cartridge in combination with the ceramic filter membrane structure. The design of multiple filter cartridges and ceramic filter membrane structures is combined with the design and use of diverter pipes to mainly perform diversion filtration on the fluid. On the one hand, it is to improve the filtration efficiency, that is, through the multi-component flow filtration method, the appropriate cleanliness of the filtration structure can be maintained to avoid excessive filtration and the problem of reduced filtration effect. On the other hand, it is mainly to protect the entire device to avoid sudden increase in flow and the problem of pipe burst.

[0012] Preferably, a filter cartridge is installed in a circumferential shape in the inner cavity of the shell, a ceramic filter membrane structure is arranged in the inner cavity of the filter cartridge, and a diverter pipe is installed at a port of the filter cartridge.

[0013] Preferably, a detection tube is installed through the inner cavity of the shell, one end of the detection tube passes through the shell and extends to the outside of the shell, and the end of the detection tube located on the outside of the shell is docked with the air pressure detection device, the other end of the detection tube is installed on the filter cartridge and communicated with the inner cavity of the filter cartridge, and a pressure gauge for displaying the internal air pressure is installed at the shell position of the air pressure detection device.

[0014] Preferably, a connecting pipe is butt-jointedly installed at one end of the diverter pipe, and the connecting pipe is connected to a port position of the heat dissipation pipe through a pipe butt-jointing mechanism.

[0015] Preferably, the inner diameter of the connecting pipe is larger than that of the shunt pipe, and the connecting pipe is of a stainless steel short pipe structure.

[0016] Preferably, a clamping groove is formed on one side of the snap ring, a limiting ring is installed in the inner cavity of the clamping groove, rubber sleeves are arranged at both ends of the fixed ring, grooves are formed on one side of the rubber sleeves, and multiple reinforcing ribs are arranged on the outer ring of the connecting pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. For this silicon carbide ceramic membrane filter for gas-solid separation, in terms of gas transmission, multiple pipe docking mechanisms are equipped on the main body. These pipe docking mechanisms can connect multiple sections of pipes in series to form a complete whole. Effectively eliminating the risk of gas leakage during transmission, thus ensuring both safe and efficient gas transmission.

[0019] 2. From the perspective of heat dissipation function, the heat dissipation device is exquisitely designed. Among them, the fixing plate plays a role in supporting and fixing, and the grooves provided on it can fix the heat dissipation pipes on the main body. Moreover, the heat dissipation fins installed on both sides of the fixing plate greatly expand the contact area with the air. When heat is generated during the operation of the device, the air comes into full contact with the heat dissipation fins, and the heat can be quickly dissipated from the heat dissipation fins. Enabling the heat absorbed by the fixing plate to be released rapidly, thereby ensuring that the entire device is always in a good temperature environment and avoiding malfunctions or performance degradation caused by overheating.

[0020] 3. For the gas-solid separation device, the outer shell is an important part of the entire gas-solid separation device, and the air pressure detection device installed on it can monitor the air pressure condition inside the outer shell in real time and accurately. At the rear of the air pressure detection device, the ceramic membrane filtration device plays a core filtration function. The shunt pipe installed on the ceramic membrane filtration device and the connecting pipe on the shunt pipe work together with the entire system. Particularly, the shunt pipe is connected to the heat dissipation pipe through the pipe docking mechanism. Such a connection method enables the cooled air flow to be evenly divided into multiple sections of air flow through the shunt pipe and then smoothly transmitted into the ceramic membrane separation device at the rear. Greatly improving the filtration and separation speed of the cooled air flow, and significantly enhancing the efficiency and quality of gas-solid separation.

[0021] 4. Finally, the detection pipe installed behind the air pressure detection device enables the entire device to accurately detect the air pressure inside the outer shell for air pressure monitoring, and timely and accurately display the detected air pressure value on the air pressure gauge installed on the outside. This enables the operator to conveniently obtain the air pressure information. Once abnormal air pressure is found, adjustments can be made quickly, thereby ensuring that the entire device always operates stably and reliably under suitable air pressure conditions.

[0022] 5. By using the connecting pipe, fixing ring and supporting ring in cooperation, the service life of the pipeline can be extended to a certain extent. The connecting pipe can protect the surface of the pipeline, thus preventing the surface of the pipeline from being damaged due to impact. The supporting ring is used to support the shape of the pipeline to prevent the cross-section of the pipeline from being squeezed and fractured. Brief Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment: Please refer to Figures 1-5 , the present invention provides a technical solution: a silicon carbide ceramic membrane filter for gas-solid separation, including a main body 1, a heat dissipation device 2 is installed on the main body 1, a gas-solid separation device 3 is installed on the left side of the heat dissipation device 2, an outlet pipe 4 is installed on the left side of the gas-solid separation device 3, and a plurality of pipeline docking mechanisms 5 are installed on the main body 1.

[0031] The pipeline docking mechanism 5 includes a connecting pipe 501. A fixing ring 502 is arranged in the inner cavity of the connecting pipe 501. Supporting rings 503 are arranged on both sides of the fixing ring 502. A docking pipe 504 is sleeved on the outer ring of the supporting ring 503. A clamping ring 506 is sleeved on the outer ring of the docking pipe 504. Both ends of the connecting pipe 501 are connected with clamping plates 505. One end of the clamping plate 505 is connected with the clamping ring 506. Connecting plates 509 are arranged on both sides of the clamping plate 505. A threaded hole 510 is formed through the top of the connecting plate 509. A screw 511 is threadedly connected in the inner cavity of the threaded hole 510. A nut 512 is sleeved on the outer ring of the screw 511.

[0032] Wherein, a clamping groove 507 is formed on one side of the clamping ring 506. A limiting ring 508 is installed in the inner cavity of the clamping groove 507. Rubber sleeves 513 are arranged at both ends of the fixing ring 502. A groove 514 is formed on one side of the rubber sleeve 513. Multiple reinforcing ribs 515 are arranged on the outer ring of the connecting pipe 501.

[0033] The pipeline docking mechanism 5 on the main body 1 is installed at the port position of the heat dissipation pipe 15, so as to connect multiple sections of pipelines in series into a whole, avoiding gas leakage during the transmission process. Specifically, in actual use, the number of filtering or heat dissipation structures of the whole device can be increased according to requirements to meet the usage requirements.

[0034] In this embodiment, in actual use, by adding the pipeline docking mechanism 5 at the port position of the heat dissipation pipe 15, the heat dissipation path in the heat dissipation structure can be increased or decreased, which is completely adjusted according to actual needs. Thus, while achieving the best heat dissipation effect, the optimal pipeline design and layout can be realized, reducing production costs and energy consumption. The pipeline docking mechanism 5 can connect multiple external pipelines in series with the device, thereby forming a complete whole, effectively eliminating the risk of gas leakage during the transmission process, and ensuring the safety and efficiency of gas transmission.

[0035] Wherein, the heat dissipation device 2 includes a fixing plate 6. The fixing plate 6 is of a split structure. Grooves 14 are formed on the opposite side surfaces of the fixing plate 6. A heat dissipation pipe 15 is arranged in the inner cavity of the groove 14. Heat dissipation fins 7 are installed on both sides of the fixing plate 6. The specific shape of the groove 14 is S-shaped, and its inner size is the same as the outer size of the heat dissipation pipe 15. During use, the heat dissipation pipe 15 can be clamped in the inner cavity of the groove 14 to keep the whole heat dissipation device 2 as stable as possible and not affected by air flow. The heat dissipation fins 7 are designed with metal sheets having good thermal conductivity, such as copper sheets. By the heat dissipation fins 7, the contact area with air is enlarged, so that the heat absorbed by the fixing plate 6 can be dissipated more quickly.

[0036] Among them, on the side of the fixed plate 6 and at the position behind the groove 14, a heat-conducting metal rod is installed in a penetrating manner along the path direction of the groove 14. After the installation of the heat-conducting metal rod, especially after the installation of the heat dissipation pipe 15, it can closely adhere to the heat dissipation pipe 15. The other end of the heat-conducting metal rod is in contact with the heat sink 7. In this way, during subsequent use, the heat carried in the heat dissipation pipe 15 can be transferred to the external heat sink 7 for heat exchange operation in the first time.

[0037] In this embodiment, when the device operates to generate heat, the air is in full contact with the heat sink 7, and the heat can be quickly dissipated from the heat sink 7, enabling the heat absorbed by the fixed plate to be quickly released, thereby ensuring that the entire device is always in a good temperature environment and avoiding failures or performance degradation caused by overheating.

[0038] Among them, the gas-solid separation device 3 includes a housing 13, and a pressure detection device 11 is installed on the outer wall of the housing 13. The pressure detection device 11 mainly monitors the internal pressure of the gas-solid separation device 13 in real time through a sensor structure to ensure the safety and stability of the operation of the entire device.

[0039] Among them, a filter cylinder 10 is installed in a circumferential shape in the inner cavity of the housing 13. A ceramic filter membrane structure is arranged in the inner cavity of the filter cylinder 10. The right port of the filter cylinder 10 is butt-connected with a shunt pipe 9. The design of the filter cylinder 10 is mainly for installing and protecting the ceramic filter membrane structure. By flowing through the filter cylinder 10 and cooperating with the ceramic filter membrane structure to achieve the filtering purpose. The design of multiple filter cylinders 10 and the ceramic filter membrane structure, combined with the design and use of the shunt pipe 9, is mainly for shunting and filtering the fluid. On the one hand, it is to improve the filtering efficiency, that is, through the multi-component shunt filtering method, the appropriate cleanliness of the filtering structure can be maintained, and the problem of reduced filtering effect due to over-filtration will not occur. On the other hand, it is mainly to protect the entire device and avoid the problem of burst pipes caused by sudden increase in flow rate.

[0040] In this embodiment, the pressure detection device can monitor the internal pressure condition of the housing in real time and accurately. At the rear side of the pressure detection device, the shunt pipe 9 installed on the ceramic membrane filtering device and the connecting pipe on the shunt pipe 9 work together with the entire system. Especially, the shunt pipe 9 is connected to the heat dissipation pipe through a pipeline docking mechanism. Such a connection method enables the cooled air flow to be evenly divided into multiple air flows through the shunt pipe and then smoothly transmitted into the ceramic membrane separation device at the rear, greatly improving the filtering and separation speed of the cooled air flow, and significantly enhancing the efficiency and quality of gas-solid separation.

[0041] Among them, a detection tube is installed in a penetrating manner in the inner cavity of the outer shell 13. One end of the detection tube penetrates through the outer shell 13 and extends to the outside of the outer shell 13. And one end of the detection tube located outside the outer shell 13 is butt-connected and installed with the air pressure detection device 11. The other end of the detection tube is installed on the filter cartridge 10 and is communicated with the inner cavity of the filter cartridge 10. An air pressure gauge 12 for displaying the internal air pressure is installed at the position of the outer shell of the air pressure detection device 11.

[0042] In this embodiment, the main purpose of designing the detection tube is to provide installation and placement for the circuit and sensors of the air pressure detection device 11. And the sensor unit of the air pressure detection device 11 extends out of the detection tube and protrudes into the inner cavity of the filter cartridge 10. And the connection position is sealed to avoid gas leakage. Finally, the data detected by the sensor of the air pressure detection device 11 is directly displayed on the air pressure gauge 12 for the convenience of the operator to view in real time.

[0043] Among them, one end of the shunt tube 9 is butt-connected and installed with a connecting tube 8. The connecting tube 8 is connected to the port position of the heat dissipation tube 15 through a pipeline docking mechanism 5. The inner diameter of the connecting tube 8 is larger than that of the shunt tube 9. And the connecting tube 8 is of a stainless steel short tube structure.

[0044] In this embodiment, the main function of the connecting tube 8 is to connect the heat dissipation device 2 and the gas-solid separation device 3. With the design of the shunt tube 9, the cooled gas is divided into multiple strands and enters the filter cartridge 10 for filtration, which can effectively perform the pressure division operation and improve the safety and stability of the entire device.

[0045] Working principle: In actual use, first, the main body 1, the heat dissipation tube 15 and the connecting tube 8 are connected through the pipeline docking mechanism 5 so that they are connected in series into a complete whole. Then, the gas will first pass through the heat dissipation tube 15, and the heat dissipation tube 15 is connected to the heat dissipation device 2. In this process, the heat carried by the gas will be conducted to the fixing plate 6 through the heat dissipation tube 15. The fixing plate 6 plays a role as a heat conduction transfer. Then the heat will be dissipated into the surrounding air through the heat dissipation fins 7 connected to the fixing plate 6. This heat dissipation link can effectively reduce the temperature of the gas and prepare for the subsequent process.

[0046] Next, the gas cooled by heat dissipation will enter the gas-solid separation device 3 through the connecting tube 8. In the gas-solid separation device 3, the gas will be subjected to preliminary separation treatment. After that, the gas is separated and enters the ceramic membrane filtration device 10 through the shunt tube 9 behind the connecting tube 8. The ceramic membrane filtration device 10 has a precise filtration function and can perform more detailed separation and filtration on the gas.

[0047] After passing through the ceramic membrane separation device 10, the gas will enter the outer shell 13 and then enter the next process through the outlet pipe 4. During this process, the solid substances will be left inside the ceramic membrane separation device 10 because they cannot pass through the ceramic membrane filtration device 10.

[0048] Meanwhile, in order to ensure the stability and safety of the pressure inside the entire device, the air pressure detection device 11 will play an important role. The air pressure detection device 11 will check the pressure inside the outer shell 13 through the detection pipe at the rear side and display the detected pressure value on the air pressure gauge 12 in real time. In this way, the operator can timely understand the pressure situation inside the device so as to make a quick response when abnormalities occur.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
