Specific implementation method:

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] like Figure 1 - Fig. 9 As shown, an air intake device of a carbon dioxide compressor includes a compressor body 1 fixed on a support frame, and a driving member for driving the compressor body 1 to operate, multi-stage buffer members are fixedly connected to both sides of the compressor body 1, and the buffer members include an air intake buffer tank 2, and a pretreatment component 3 is fixedly connected to the air intake end of the air intake buffer tank, and the pretreatment component 3 includes a filter component and a drying component, and the filter component and the drying component are fixed in a pretreatment box 4 in sequence, and the filter component can dynamically adjust the filtering accuracy according to the gas concentration, and the drying component can be regenerated and restore its drying capacity.

[0048] Specifically, the compressor body 1 is driven by a driving member (such as a motor or an engine) to compress the input carbon dioxide gas to increase its pressure. In order to ensure the smoothness of the compression process and the long-term stable operation of the compressor body 1, multi-stage buffer members are arranged on both sides of the compressor body 1, among which the main one used for air intake is the air intake buffer tank 3.

[0049] The air intake buffer tank 3 plays a key role in the operation of the compressor body 1. It receives carbon dioxide gas from the outside and performs preliminary treatment through the pretreatment component 3. The pretreatment component 3 is composed of a filter component and a drying component, which are connected in sequence and fixedly installed in the pretreatment box 4 to ensure that the gas reaches a suitable purity and dryness before compression.

[0050] The filter assembly can dynamically adjust its filtration accuracy according to the change of gas concentration, which means that when the impurity concentration in the gas is high, the filter assembly will improve the filtration efficiency and intercept more impurities; and when the gas is relatively pure, the filtration accuracy will be appropriately reduced to reduce energy consumption. This dynamic adjustment capability improves the adaptability and efficiency of the compressor body 1.

[0051] The drying component is responsible for removing moisture from the gas to prevent it from freezing during the compression process or causing other adverse consequences. Unlike traditional drying components, this drying component has regeneration capabilities and can restore its drying capacity under certain conditions, thereby extending its service life and reducing replacement costs.

[0052] The filter assembly includes a filter element, an adjusting drive element and a gas concentration detector 5. The filter element is fixed in a pretreatment box 4, and the top and bottom of the filter element are respectively fixedly connected to the output ends of the adjusting drive element. The adjusting drive element is fixed on the outer wall of the pretreatment box 4. The filtering surface of the filter element is arranged opposite to the air intake pipe. The gas concentration detector 5 is fixed on the air intake pipe. The air intake pipe is fixed on the side of the pretreatment box 4. The adjusting drive element can drive the filter element to be in an arc state or a plane state to change the filtering accuracy of the filter element. The gas concentration detector 5 is electrically connected to the control system 6 for transmission, and the adjusting drive element is electrically connected to the control system 6 for control.

[0053] The filter element includes a filter plate 7, which has a cavity inside and is supported by an elastic material. The elastic material may be stainless steel 304, stainless steel 316, a nickel-based alloy, a high-performance plastic or a carbon fiber reinforced composite material. The top and bottom of the filter plate 5 are fixedly connected to the inner wall of the pretreatment box 4 respectively.

[0054] The adjusting drive component includes an air pump 8 and an air suction pump 9, which are arranged opposite to each other and are respectively fixed on the outer wall of the pretreatment box 4. The air pump 8 and the air suction pump 9 are respectively extended into the pretreatment box 4 through air pipes and are fixedly connected with the cavity in the filter hole plate 5, and a first solenoid valve 10 is respectively fixed on the two air pipes. The air pump 8, the air suction pump 9 and the two first solenoid valves 10 are respectively electrically connected to the control system 6.

[0055] Specifically, the gas enters the pretreatment box 4 through the air intake pipe, and a gas concentration detector 5 is provided on the air intake pipe to detect the concentration of the incoming gas in real time. The gas concentration detector 5 transmits the detected data to the control system 6 through electrical connection.

[0056] The filter element is composed of a filter plate 7, the interior of which is a cavity. The filter plate 7 is made of elastic material, and different elastic materials can be selected as needed, such as stainless steel 304, stainless steel 316, nickel-based alloy, high-performance plastic or carbon fiber reinforced composite material.

[0057] The top and bottom of the filter plate 7 are respectively fixedly connected to the inner wall of the pretreatment box 4, and the top and bottom thereof are also fixedly connected via the output end of the adjusting drive member.

[0058] The regulating drive member comprises an air charging pump 8 and an air suction pump 9, which are arranged opposite to each other and fixed on the outer wall of the pre-processing box 4. They are respectively extended into the pre-processing box 4 through air pipes and communicated with the cavity in the filter plate 7.

[0059] The inflation pump 8 and the suction pump 9 are controlled by the control system 6 respectively. When the control system 6 receives the signal from the gas concentration detector 5, it controls the operation of the inflation pump 8 or the suction pump 9 according to the preset filtering accuracy requirements.

[0060] When the air pump 8 is working, air is inflated into the filter hole plate 7 through the air pipe, so that the filter hole plate 7 expands into an arc state, thereby reducing the effective area of ​​the filter hole and improving the filtering accuracy.

[0061] When the air suction pump 9 is working, air is sucked from the filter hole plate 7 through the air pipe, so that the filter hole plate 7 shrinks into a flat state, increasing the effective area of ​​the filter hole and reducing the filtering accuracy.

[0062] A first solenoid valve 10 is fixed to the air pipes of the inflation pump 8 and the suction pump 9 respectively, for controlling the flow of gas. The first solenoid valve 10 is also controlled by the control system 6 .

[0063] The control system 6 automatically adjusts the working states of the inflation pump 8 and the suction pump 9, and the switch of the first electromagnetic valve 10 according to the detection result of the gas concentration detector 5, so as to achieve accurate adjustment of the filtering accuracy of the filter element.

[0064] In this way, the filter component can automatically adjust the filtration accuracy according to different gas concentrations and filtration requirements, ensuring the filtration effect while also improving the intelligence and automation level of the equipment.

[0065] The drying component includes a drying plate 11 and a regeneration processing component. The drying plate 11 is arranged at the side end of the filter hole plate 7, and the drying plate 11 is fixed in the pretreatment box 4 and faces the air outlet pipe. A humidity sensor 12 is fixed on the air outlet pipe. The humidity sensor 12 is electrically connected to the control system 6. The drying plate 11 can absorb moisture in the gas after filtering the filter hole plate 7. Regeneration processing components are arranged on both sides of the drying plate 11, and the regeneration processing components are fixed on the pretreatment box 4. The drying plate 11 can restore the moisture in the adsorbed gas through the processing of the regeneration processing components.

[0066] The regeneration processing component includes a closing component and a gas introduction component. The two closing components are respectively arranged on both sides of the drying plate 11, and the closing components can close the air inlet and outlet on both sides of the drying plate 11. The gas introduction component is fixedly arranged between the closing component and the drying plate 11. The gas introduction component can introduce heating gas or cooling gas into the drying plate 11, and the gas introduction component is fixedly connected to the gas injection device.

[0067] The closed component includes two electric push rods 13 relatively fixed on the outer wall of the pretreatment box 4. The output end of the electric push rod 13 is fixedly connected to the closed baffle 13 through a connecting frame. The two closed baffles 13 are relatively inserted into the pretreatment box 4, and the opposite surfaces of the two closed baffles 13 are respectively fixed with grooves and protrusions, and the protrusions can be inserted into the grooves in a fit. The electric push rod 13 is electrically connected to the control system 6.

[0068] The gas introduction component includes an air guide box 14, which is fixed on the outer wall of the pretreatment box 4. Two regeneration gas inlet pipes are fixedly connected to the output end of the air guide box 14. The two regeneration gas inlet pipes are respectively inserted into the pretreatment box 4 and are arranged on both sides of the drying plate 11. Two regeneration gas outlet pipes are fixed on the other side wall of the pretreatment box 4 opposite to the two regeneration gas inlet pipes. The two regeneration gas inlet pipes pass through the pretreatment box 4. The regeneration gas inlet pipes and the regeneration gas inlet pipes are respectively fixed with second solenoid valves 16. The air guide box 14 is connected to the gas injection device through a pipeline, and the second solenoid valve 16 is electrically connected to the control system.

[0069] Specifically, the drying plate 11 is arranged at the side end of the filter plate 7 and fixed in the pretreatment box 4. When the gas containing moisture passes through the filter plate 7 and is filtered, it enters the drying plate 11, and the material inside the drying plate 11 absorbs the moisture in the gas to achieve gas drying. The regeneration treatment component includes a sealing component and a gas introduction component, which are respectively arranged on both sides of the drying plate 11.

[0070] The sealing assembly is composed of two electric push rods 13 and a sealing baffle 13. The electric push rod 13 is connected to the sealing baffle 13 through a connecting frame. When the electric push rod 13 is working, it drives the sealing baffle 13 to be inserted into or withdrawn from the pretreatment box 4, so as to seal the air inlet and outlet on both sides of the drying plate 11. The opposite surfaces of the sealing baffle 13 are respectively provided with grooves and protrusions. When the two sealing baffles 13 are closed, the protrusions are inserted into the grooves to ensure the sealing effect.

[0071] The gas introduction assembly is composed of an air guide box 14, a regeneration gas inlet pipe, a regeneration gas outlet pipe and a second solenoid valve 16. The air guide box 14 is fixed on the outside of the pretreatment box 4 and connected to the gas injection device through a pipeline. The regeneration gas inlet pipe is output from the air guide box 14, respectively inserted into the pretreatment box 4, and arranged on both sides of the drying block 11. A regeneration gas outlet pipe is fixed on the other corresponding side wall. When regeneration is required, the second solenoid valve 16 is controlled to open by the control system, and the gas injection device injects heating or cooling gas into the air guide box 14, and then introduces it into the drying block 11 through the regeneration gas inlet pipe, so that the material in the drying block 11 is heated or cooled, and the adsorbed moisture is released, and then discharged through the regeneration gas outlet pipe.

[0072] The humidity sensor 12 monitors the humidity of the gas entering the outlet pipe. When the drying plate 11 is detected to be saturated, the system starts the regeneration process. The control system controls the sealing component to seal the air inlet and outlet on both sides of the drying plate 11, and then controls the gas introduction component to introduce heating or cooling gas for regeneration. After the regeneration is completed, the sealing component is opened, the drying plate 11 resumes the adsorption function, and enters the next drying-regeneration cycle.

[0073] It also includes an auxiliary regulating component, which is fixed on the pipeline connecting the air intake buffer tank 2 and the pretreatment component 3. The auxiliary regulating component can adjust the flow rate and direction of the control gas entering the buffer.

[0074] The auxiliary adjustment component includes a guide orifice 17, and the guide orifice 16 is fixed in the connecting pipe between the air intake buffer tank 2 and the pretreatment component 3. The guide orifice 16 is rotatably connected to a rotating shaft, and a plurality of blades 18 are fixed in a ring shape on the rotating shaft, and the blades 18 are inclined relative to the side of the guide orifice 16. The blades 18 are arranged in a gear ring 19, and the gear ring 19 is fixedly connected to the rotating shaft through a connecting rod. The outer diameter of the gear ring 18 is larger than the outer diameter of the connecting pipe between the air intake buffer tank 2 and the pretreatment component 3. Sealing convex rings are fixed on both sides of the gear ring 18, and a sealing annular groove is fixed on the side wall of the connecting pipe. The sealing convex ring can be inserted into the sealing annular groove. The outer side of the gear ring 18 is meshed with a gear 20, and the gear 20 is fixedly connected to the output end of the drive motor 21. The drive motor is fixed on the outer wall of the connecting pipe between the air intake buffer tank 2 and the pretreatment component 3, and the drive motor 21 is electrically connected to the control system.

[0075] Specifically, the guide orifice plate 17 is fixed in the connecting pipe between the intake buffer tank 2 and the pretreatment assembly 3, and a rotatable rotating shaft is provided on the guide orifice plate 17, on which a plurality of inclined blades 18 are fixed. The blades 18 are contained in the gear ring 18, and the gear ring 18 is connected to the rotating shaft through a connecting rod to ensure synchronous rotation.

[0076] The outer diameter of the gear ring 18 is larger than the outer diameter of the connecting pipe, and sealing convex rings are provided on both sides of the gear ring 18. The side wall of the connecting pipe is fixed with sealing annular grooves, and the sealing convex rings can be closely fitted and inserted into these sealing annular grooves to ensure that there is no leakage when the gas flows.

[0077] The outer side of the gear ring 18 is meshed with the gear 20, and the gear 20 is fixedly connected to the output end of the drive motor 21. The drive motor is fixed to the outer wall of the connecting pipe and is electrically connected and controlled by the control system 6. The control system 6 can adjust the speed and direction of the drive motor as needed, thereby controlling the rotation of the gear ring 18 and the blades 18.

[0078] When the driving motor 21 is started, it drives the gear 20 to rotate. Due to the meshing relationship between the gear 20 and the gear ring 18, the gear ring 18 will also rotate accordingly. Since the blades 18 are fixed in the gear ring 18 and are tilted relative to the side of the guide orifice plate 17, the blades 18 will rotate with the rotation of the gear ring 18. The rotation will change the flow rate and direction of the gas when passing through the guide orifice plate 17, thereby achieving precise regulation of the gas entering the intake buffer tank 2.

[0079] The air intake buffer tank 2 includes an outer tank body 22 and an inner tank body 23. The outer tank body 22 is inserted into the inner tank body 23, and a rubber filling layer is fixed between the outer tank body 22 and the inner tank body 23. The inner tank body 23 adopts a corrugated tank with a certain elasticity. The inner tank body 23 can be made of stainless steel (especially 304 or 316 models), polytetrafluoroethylene, synthetic rubber or polyetheretherketone. The shape of the inner tank body 23 is a cube, and a plurality of adjusting parts are fixed in sequence in the inner tank body 23 from the air inlet end to the air outlet end. The adjusting parts can adjust the flow path of the gas in the inner tank body 23.

[0080] The adjusting member includes four partitions 24, which are hinged on the four side surfaces inside the inner tank body 23 respectively. Angle springs are fixedly connected between the partitions 24 and the inner side surfaces of the inner tank body 23, and the four partitions 24 are arranged in sequence from the air inlet end to the air outlet end of the inner tank body 23. The length of the partition 24 is less than the inner length of the inner tank body 23. A plurality of bionic shark fin plates 25 are fixed on both side surfaces of the partition 24 respectively. The plurality of bionic shark fin plates 25 are evenly spaced on the side surfaces of the partition 24, and the bionic shark fin plates 25 imitate the design of shark fins. The streamlined design of shark fins helps to guide gas flow, reduce resistance, and enhance lift or generate pressure difference under specific conditions. The partition 24 can swing at a certain angle, and can restore to its original state by using angle springs. The height of the bionic shark fin plate 25 on the side of the air inlet end of the partition 24 facing the inner tank body 23 is greater than the height of the other side of the partition 24.

[0081] Specifically, the intake buffer tank 2 is composed of an outer tank body 22 and an inner tank body 23. The outer tank body 22 is sleeved on the outside of the inner tank body 23, and a rubber layer is filled between the two to provide shock absorption and heat insulation effects. The inner tank body 23 adopts an elastic corrugated tank design, and the material can be stainless steel (such as 304 or 316 model), polytetrafluoroethylene, synthetic rubber or polyetheretherketone, and the shape is a cube.

[0082] A plurality of adjusting parts are sequentially arranged inside the inner tank body 23 from the air inlet end to the air outlet end, mainly composed of four partitions 24. These partitions 24 are hingedly mounted on the four sides of the inner tank body 23 and connected to the sides of the inner tank body through angle springs to maintain their stability and recovery.

[0083] Multiple bionic shark fin plates 25 are installed on both sides of each baffle 24. These bionic shark fin plates 25 imitate the streamlined design of shark fins, which helps to optimize the gas flow path, reduce flow resistance, and generate lift or pressure difference through their special shapes under certain conditions. The length of the baffle 24 is less than the internal length of the inner tank 23, allowing the gas to change direction and speed when flowing between the baffles.

[0084] When the gas passes through the inner tank 23, the partition 24 can swing at a certain angle due to the flow force and pressure changes of the gas. This swing, combined with the design of the bionic shark fin plate 25, can dynamically adjust the gas flow path, optimize the flow efficiency, and reduce the energy loss caused by direct impact or eddy current. When the gas flow weakens or changes direction, the angle spring will help the partition 24 return to its original position to maintain the stability and consistency of the system.

[0085] Through dynamic adjustment of the regulating parts, the air intake buffer tank 2 can effectively manage the gas pressure and flow entering the system, reduce pressure fluctuations and flow instability, thereby protecting subsequent equipment from sudden shocks or overloads, and improving the operating efficiency and stability of the overall system.

[0086] Actual working process:

[0087] During the initialization and monitoring phase, the system will monitor the gas concentration detector 5 configured on the air intake pipe in real time to capture accurate data of the initial gas concentration and transmit it immediately to the core control system 6 for in-depth analysis.

[0088] In the process of intelligently adjusting the filtering accuracy, the control system 6 accurately controls the operating state of the adjusting driving member according to the obtained gas concentration data. Through the fine operation of the first solenoid valve 10, the inflation pump 8 or the suction pump 9 is precisely regulated to inflate or suction the inner cavity of the filter plate 7, so that the filter plate 7 can be flexibly switched between the arc state and the plane state, so as to achieve the purpose of dynamically adjusting the filtering accuracy.

[0089] Entering the gas pretreatment and drying stage, the gas preliminarily treated by the filter element will enter the drying plate 11 for efficient moisture adsorption. At the same time, the humidity sensor 12 will continuously monitor the humidity of the gas in the outlet pipe. Once the humidity exceeds the preset threshold range, the automatic working mode of the regeneration processing component will be immediately triggered.

[0090] During the intelligent regeneration process, the control system 6 will accurately control the operation of the electric push rod 13, drive the closed baffle 13 to quickly close the two side channels of the drying plate 11, and effectively block the gas flow. Subsequently, the heated nitrogen is accurately introduced through the air guide box 14 and the regeneration gas inlet pipe to make it fully contact with the drying plate 11. In the process of flowing through the drying plate 11, the heated nitrogen will provide sufficient energy to prompt the drying plate 11 to release the adsorbed moisture. The released moisture will be exported from the system through the regeneration gas outlet pipe together with the gas. After the regeneration process is completed, in order to restore the adsorption capacity of the drying plate 11, the system will stop the introduction of heated nitrogen and instead introduce cooling nitrogen to cool the drying plate 11. The cooling nitrogen also flows through the drying plate 11, effectively reducing its temperature. After the drying plate 11 is cooled to a certain time, the control system 6 will again control the electric push rod 13 to drive the closed baffle 13 to return to the initial state, and the system will then re-enter the drying working mode.

[0091] In terms of flow rate and direction optimization, when the gas flows through the pretreatment component 3 and enters the auxiliary adjustment component, the control system 6 will accurately control the start of the auxiliary adjustment component. The drive motor 21 will drive the gear 20 to rotate, thereby driving the gear ring 19 and the blades 18 to rotate synchronously. The unique tilting design of the blades 18 combined with the rotation of the gear ring 19 can jointly achieve fine adjustment of the flow rate and direction of the gas when it enters the buffer tank 2.

[0092] Finally, in the buffer and flow path optimization link, the carefully designed bionic shark fin plate 25 in the intake buffer tank 2 imitates the natural shape of shark fins, effectively guiding the gas to form a complex and orderly flow path in the inner tank body 23. In addition, the ingenious combination of the partition 24 and the angle spring enables the partition 24 to automatically adjust its angle according to the change of gas pressure;

[0093] The angle spring is an elastic element connecting the partition 24 and the inner tank 23. Its main function is to allow the partition 24 to deflect to a certain extent when subjected to gas pressure.

[0094] Without considering the influence of other factors, it is assumed that the force of the angle spring is simplified to a spring-like force F=kX, where F is the force generated by the angle spring, k is the stiffness coefficient of the angle spring (similar to the stiffness coefficient of a spring), and X is the deflection of the diaphragm 24 caused by the change in gas pressure (similar to the compression or extension of a spring).

[0095] When the gas pressure P entering the buffer tank increases, the partition 24 will be subjected to a greater thrust, causing it to deflect toward the gas outlet end of the inner tank body 23, and the deflection amount X will increase accordingly. According to F=kX, the force F generated by the angle spring will also increase accordingly to resist the deflection trend of the partition 24 and maintain the stability of the gas flow in the inner tank body 23.

[0096] During the continuous change of the gas pressure P entering the buffer tank, a dynamic balance will be formed between the partition 24 and the angle spring. When the gas pressure P increases, the deflection of the partition 24 increases, and the force of the angle spring increases to resist the deflection; when the gas pressure P decreases, the partition 24 gradually returns to its original position, and the force of the angle spring decreases, resulting in a dynamic balance state.

[0097] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
