Description

Technical Field

[0001] This application relates to the technical field of exhaust gas treatment, and in particular to an exhaust gas treatment device for an air compressor oil tank negative pressure regulation system. Background Technology

[0002] Currently, air compressors, as devices that increase gas pressure by compressing gas, are widely used in many fields such as machinery, transportation, and metallurgy. During operation, the lubricating oil in the oil tank plays crucial roles in lubrication, cooling, and sealing. Because air compressors generate high temperatures and high pressures during operation, the lubricating oil in the tank evaporates at high temperatures and forms oil mist and oil vapor under high pressure. The issue of air compressor oil mist emissions not only involves the efficient use of energy but also concerns environmental protection and production safety. Properly handling air compressor oil mist emissions is of great significance for improving production efficiency, reducing operating costs, and minimizing negative environmental impacts.

[0003] In related technologies, a negative pressure regulating system for the air compressor oil tank is typically used to treat the oil vapor in the tank. Specifically, this system extracts the oil vapor from the tank and performs oil-vapor separation. The separated droplets flow back into the tank, while the remaining gas is directly released into the atmosphere. Some companies also use simple filtration devices to perform preliminary filtration of the oil vapor, removing larger particles and droplets before discharge.

[0004] Regarding the aforementioned technologies: after a certain period of use, the filter device is prone to blockage, resulting in insufficient gas discharge and thus a reduction in overall filtration efficiency. Utility Model Content

[0005] To reduce the possibility of decreased filtration efficiency, this application provides an exhaust gas treatment device for an air compressor oil tank negative pressure regulation system.

[0006] This application provides a tail gas treatment device for an air compressor oil tank negative pressure regulation system, which adopts the following technical solution: An exhaust gas treatment device for an air compressor oil tank negative pressure regulation system includes: The housing has an air outlet. The filter module is installed inside the housing; A negative pressure module is installed on the housing. When the filter module is damaged, the negative pressure module can drive the gas inside the housing to flow out from the outlet.

[0007] By adopting the above technical solution, the enclosure provides a closed space for exhaust gas treatment, ensuring that the treatment process takes place in a relatively stable environment. The filter module, located inside the enclosure, filters the oil-mist-containing gas entering the enclosure, removing impurities and harmful substances, thus purifying the gas. Furthermore, when the filter module experiences blockage, a negative pressure module activates, driving the gas inside the enclosure to flow out of the outlet, thereby increasing the amount of gas passing through the filter module. This ensures that the oil-mist-containing gas continuously flows into the enclosure for treatment, guaranteeing the continuity and efficiency of the entire treatment process, and thus reducing the possibility of decreased filtration efficiency.

[0008] Optionally, the filtration module includes a first filter element, a second filter element, and a third filter element, which are detachably disposed in the housing in sequence, and the negative pressure module is disposed near the air outlet.

[0009] By adopting the above technical solution, the first, second, and third filter elements sequentially perform multi-layer filtration on the gas entering the chamber, removing impurities and harmful substances layer by layer. This improves the filtration efficiency and effect, ensuring that the final discharged gas better meets emission standards. Simultaneously, the three filter elements are detachably installed within the chamber, facilitating timely removal and replacement or cleaning when blockage or adsorption saturation occurs after a period of use, maintaining the optimal performance of the filtration module. Furthermore, the negative pressure module is positioned near the outlet, creating a more stable and suitable negative pressure environment within the chamber, promoting smooth gas flow out of the chamber after passing through multiple filter elements. This ensures the entire gas treatment process runs smoothly, guaranteeing continuous and efficient gas treatment to meet emission requirements.

[0010] Optionally, the housing has two movable slots, which are arranged along the height of the housing. The second filter element is movably inserted into one of the movable slots, and the third filter element is movably inserted into the other movable slot. The first filter element is located on the side of the movable slot away from the air outlet. A flow guiding assembly is provided inside the housing, which abuts against the second filter element and the third filter element respectively. The flow guiding assembly is used to allow the gas to pass through the second filter element and the third filter element in sequence.

[0011] By adopting the above technical solution, movable slots are opened along the height direction on the housing, allowing the second and third filter elements to be movably inserted into these slots, facilitating the installation and replacement of the filter elements. The first filter element is positioned on the side of the movable slot furthest from the air outlet, allowing for preliminary filtration of the gas. The flow-guiding components inside the housing contact the second and third filter elements respectively, guiding the gas through them sequentially along a preset path, achieving multi-stage filtration. This more effectively separates oil mist and treats the gas to meet emission standards.

[0012] Optionally, the flow guiding assembly includes a first flow guiding plate and a second flow guiding plate, the first flow guiding plate and the second flow guiding plate being spaced apart from each other, the second filter and the third filter being located between the first flow guiding plate and the second flow guiding plate, the end of the first flow guiding plate near the second filter being spaced apart from the inner wall of the housing, and the end of the second flow guiding plate near the third filter being spaced apart from the inner wall of the housing.

[0013] By adopting the above technical solution, the first and second guide plates are spaced apart and symmetrically arranged, with the second and third filter elements located between them. The end of the first guide plate near the second filter element is spaced from the inner wall of the chamber, and the end of the second guide plate near the third filter element is also spaced from the inner wall. This structure ensures that when gas flows within the chamber, it passes sequentially through the second and third filter elements along a specific path, achieving orderly guidance. This not only extends the residence time of the gas in the filtration module, allowing for more thorough contact between the gas and the filter elements, but also ensures effective filtration, thereby improving the overall filtration effect of the exhaust gas treatment device and enabling the emitted gas to better meet environmental standards.

[0014] Optionally, the second filter element and the third filter element are respectively provided with baffles, and when the second filter element and the third filter element are inserted into the movable groove, the baffles block the movable groove.

[0015] By adopting the above technical solution, the baffles installed on the second and third filter elements can seal the movable groove when the second and third filter elements are inserted into the movable groove, which can prevent gas from leaking from the movable groove and ensure that the gas flows through each filter element according to the preset path. This ensures the sealing and effectiveness of the filtration process and improves the filtration efficiency and stability of the exhaust gas treatment device of the entire air compressor oil tank negative pressure regulation system.

[0016] Optionally, slots are respectively opened on the housing corresponding to the positions of the first filter element and the negative pressure module, and a switch door is movably arranged on the housing. The number of the switch doors is equal to the number of the slots and is arranged in a one-to-one correspondence. The switch door is used to block the slots.

[0017] By adopting the above technical solution, slots are opened on the housing corresponding to the positions of the first filter element and the negative pressure module, and a number of openings are set up to seal the slots. This facilitates the inspection, replacement, or maintenance of the first filter element and the negative pressure module, thereby ensuring the stable operation of the exhaust gas treatment device of the entire air compressor oil tank negative pressure regulation system, and more effectively separating oil mist and treating gas so that the gas meets emission standards.

[0018] Optionally, the housing is provided with two sets of slide rails, which are parallel to each other and spaced apart. The first filter element is slidably disposed on the slide rails. A linkage component is provided between the first filter element and the housing. When one of the first filter elements moves into the housing, the linkage component can drive the other first filter element to move out of the housing.

[0019] By adopting the above technical solution, two sets of parallel and spaced slide rails are installed inside the housing, allowing the first filter element to slide on them. Simultaneously, a linkage component between the first filter element and the housing allows the other first filter element to move out of the housing as one moves into the housing. This design facilitates replacement or maintenance of the first filter element without shutting down the machine, ensuring the continuous and stable operation of the exhaust gas treatment device of the air compressor oil tank negative pressure regulation system, and improving overall work efficiency.

[0020] Optionally, the linkage component includes a gear and a rack. The rack is disposed on the first filter element, and the gear is rotatably connected to the housing and located between the two sets of slide rails. When the first filter element is slidably disposed on the slide rail, the rack and the gear mesh with each other.

[0021] By adopting the above technical solution, when one of the first filter elements moves into the housing on the slide rail, the rack on the first filter element meshes with the gear rotatably connected in the housing and located between the two sets of slide rails. Due to the transmission action of the gear, the rack on the other first filter element will move, thereby causing the other first filter element to move out of the housing. This achieves the linkage effect of the two first filter elements moving in opposite directions inside and outside the housing, which facilitates the replacement or maintenance of the first filter element and ensures that the device can continuously and stably filter the gas discharged from the air compressor oil tank.

[0022] Optionally, both the second filter element and the third filter element are activated carbon filter boxes.

[0023] By adopting the above technical solution, since both the second and third filter elements use activated carbon filter boxes, activated carbon has strong adsorption properties and can deeply adsorb and filter impurities, harmful substances and residual oil mist in the passing gas, further removing pollutants in the gas, improving the degree of gas treatment, and making the final discharged gas more fully compliant with emission standards, thereby reducing the impact on the operating quality of subsequent equipment and improving the working performance and environmental protection effect of the exhaust gas treatment device of the entire air compressor oil tank negative pressure regulation system.

[0024] Optionally, the negative pressure module includes a negative pressure component and a detection component. The negative pressure component is disposed inside the housing, and the detection component is disposed on the housing. Both ends of the detection component extend to both sides of the filter module, and the detection component is electrically connected to the negative pressure component. The detection component is used to detect the pressure difference between the two sides of the filter module.

[0025] By adopting the above technical solution, the detection element is set on the housing and extends to both sides of the filter module. It can detect the pressure difference on both sides of the filter module. Since the detection element is electrically connected to the negative pressure element, when a change in the pressure difference on both sides of the filter module is detected, it can transmit a signal to the negative pressure element. The negative pressure element adjusts its working state according to the signal, thereby maintaining a suitable negative pressure environment in the housing, ensuring effective treatment of oil mist gas, so that it can better flow out from the outlet and meet the emission standards.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the filter module and the negative pressure module, the filter module can filter the gas entering the chamber to ensure that the gas meets the emission standards. When the filter module is blocked, the negative pressure module works to drive the gas in the chamber to flow out from the outlet, thereby increasing the amount of gas passing through the filter module. This allows oil mist gas to continuously flow into the chamber for treatment, which helps to reduce the possibility of reduced filtration efficiency. 2. Through the cooperation of the first filter element, the second filter element, the third filter element and the flow guiding component, the first filter element, the second filter element and the third filter element can sequentially perform multi-layer filtration on the gas entering the chamber, removing impurities and harmful substances from the gas layer by layer, which can improve the filtration efficiency and filtration effect of the gas, so that the final discharged gas can better meet the emission standards. 3. Through the cooperation of slide rails, gears and racks, when one first filter element moves into the housing on the slide rail, it can drive another first filter element to move out of the housing through the cooperation of gears and racks, thus facilitating the replacement or maintenance of the first filter element.

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses an exhaust gas treatment device for an air compressor oil tank negative pressure regulation system.

[0036] It should be noted that in the description of this utility model, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] Example 1 Reference Figure 1 and Figure 2 An exhaust gas treatment device for a negative pressure regulation system of an air compressor oil tank includes a housing 1, a filter module 2, and a negative pressure module 3. The filter module 2 is disposed inside the housing 1, and the negative pressure module 3 is disposed on the housing 1, so that when the filter module 2 is obstructed, the negative pressure module 3 can maintain a negative pressure environment inside the housing 1.

[0038] Specifically, housing 1 is the outer shell of the entire device, providing installation space and protection for internal components. In this embodiment, housing 1 is made of metal, such as stainless steel, which has good strength and corrosion resistance.

[0039] One end of the housing 1 is connected to the negative pressure regulation system of the air compressor oil tank, and the other end of the housing 1 is provided with an air outlet 11. The size of the air outlet 11 is determined according to the actual exhaust requirements, so that the gas discharged by the negative pressure regulation system of the air compressor oil tank can enter the housing 1, so that the gas can be treated by the filter module 2 to reduce the concentration of harmful substances in the gas, and the gas after passing through the filter module 2 can be discharged from the air outlet 11, thereby making the discharged gas meet the emission standards.

[0040] Reference Figure 1 The housing 1 has two movable slots 12, which are arranged along the height of the housing 1. The housing 1 also has two openings 13, with the two movable slots 12 located between the two openings 13. The housing 1 is also equipped with movable doors 14, the number of which is equal to the number of openings 13 and they are arranged in a one-to-one correspondence. The doors 14 are used to block the openings 13.

[0041] In this embodiment, the switch door 14 can be connected to the housing 1 by a hinge and fixed by a door lock or other means. The edge of the switch door 14 is usually provided with a rubber sealing gasket. When the switch door 14 is closed, the rubber sealing gasket can play a good sealing role and prevent gas leakage.

[0042] Reference Figure 3 and Figure 4 The filter module 2 includes a first filter element 21, a second filter element 22, and a third filter element 23. The first filter element 21 is detachably installed inside the housing 1 and located away from the air outlet 11.

[0043] Reference Figure 1 and Figure 4 The first filter element 21 is provided with a slot 13, which facilitates opening the switch door 14 for inspection and maintenance of the first filter element 21. The second filter element 22 is inserted into a movable slot 12, and the third filter element 23 is inserted into another movable slot 12, with the third filter element 23 located below the second filter element 22. Baffles 24 are respectively provided on the second filter element 22 and the third filter element 23.

[0044] When the first filter element 21 and the second filter element 22 are inserted into the movable groove 12, the baffle 24 can fit tightly around the movable groove 12 to seal the movable groove 12, prevent gas from leaking from the movable groove 12, and ensure that the gas is stably filtered by the second filter element 22 and the third filter element 23.

[0045] In this embodiment, the first filter element 21 is a filter screen made of woven metal wires, which can intercept larger particles of impurities and oil droplets. The second filter element 22 and the third filter element 23 both use activated carbon filter boxes. Activated carbon has a rich porous structure, which can adsorb tiny particles and harmful gases in oil mist, effectively reducing the content of harmful substances in exhaust gas.

[0046] Reference Figure 4 The housing 1 contains a flow guiding assembly 15, which includes a first flow guiding plate 151 and a second flow guiding plate 152. The first flow guiding plate 151 and the second flow guiding plate 152 are spaced apart from each other, with the top end of the first flow guiding plate 151 spaced from the inner wall of the housing 1 and the bottom end of the second flow guiding plate 152 spaced from the inner wall of the housing 1. A second filter element 22 and a third filter element 23 are located between the first flow guiding plate 151 and the second flow guiding plate 152. In this embodiment, both the first flow guiding plate 151 and the second flow guiding plate 152 are made of plastic or metal with smooth surfaces to reduce resistance to gas flow.

[0047] When the gas discharged from the negative pressure regulating system of the air compressor oil tank enters the housing 1, the gas passes through the first filter element 21, and then through the gap between the first guide plate 151 and the inner wall of the housing 1 to enter the second filter element 22. It then passes through the gap between the first guide plate 151 and the second guide plate 152 to enter the third filter element 23. Finally, it flows out from the gap between the second guide plate 152 and the inner wall of the housing 1, and then exits the housing 1 through the air outlet 11. This allows the gas to flow in the housing 1 along a predetermined path, passing through the first filter element 21, the second filter element 22 and the third filter element 23 in sequence, thereby improving the filtration effect.

[0048] Reference Figure 2 and Figure 4 The negative pressure module 3 includes a negative pressure component 31 and a detection component 32. The negative pressure component 31 is installed inside the housing 1 and is located near the air outlet 11. The negative pressure component 31 is provided with a corresponding slot 13 to facilitate maintenance of the negative pressure component 31.

[0049] In this embodiment, the negative pressure component 31 is an axial flow fan, which facilitates the use of the negative pressure component 31 to drive the gas inside the housing 1 to be discharged from the air outlet 11. In other embodiments, the negative pressure component 31 may also be configured as a variable frequency vortex fan.

[0050] The detection element 32 is disposed on the housing 1, with one end of the detection element 32 extending to the side of the first filter element 21 away from the air outlet 11, and the other end of the detection element 32 disposed close to the air outlet 11. In this embodiment, the detection element 32 is a differential pressure sensor, which facilitates the detection of the pressure difference across the first filter element 21.

[0051] The detection element 32 is electrically connected to the negative pressure element 31. When the pressure difference across the first filter element 21 meets the set value, the negative pressure element 31 does not work; when the pressure difference across the first filter element 21 exceeds the set value, it indicates that the first filter element 21 may be experiencing blockage. At this time, the negative pressure element 31 works to increase the negative pressure inside the housing 1, allowing more gas to pass through the first filter element 21, the second filter element 22, and the third filter element 23, thereby ensuring the continuity and efficiency of the entire treatment process and helping to reduce the possibility of reduced filtration efficiency.

[0052] The implementation principle of the exhaust gas treatment device for an air compressor oil tank negative pressure regulation system according to an embodiment of this application is as follows: When it is necessary to treat the exhaust gas produced by the air compressor oil tank negative pressure regulation system, the exhaust gas produced by the air compressor oil tank negative pressure regulation system is first introduced into the housing 1, so that the gas passes through the first filter element 21, the second filter element 22 and the third filter element 23 in sequence, and is discharged through the outlet 11. When the detection element 32 detects that the pressure difference on both sides of the first filter element 21 exceeds the set value, the negative pressure element 31 works to increase the negative pressure in the housing 1, adjust the pressure difference on both sides of the first filter element 21, so that more gas can pass through the first filter element 21, thereby ensuring effective treatment of oil mist gas, so that it flows out of the outlet 11 better and meets the emission standards.

[0053] Example 2 Reference Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that two sets of slide rails 16 are provided inside the housing 1. The two sets of slide rails 16 are parallel to each other and spaced apart. A linkage component 17 is provided between the first filter element 21 and the housing 1.

[0054] The first filter element 21 is slidably mounted on the slide rail 16. The linkage assembly 17 includes a gear 171 and a rack 172. The rack 172 is mounted on the first filter element 21, and the gear 171 is rotatably connected inside the housing 1 and located between the two sets of slide rails 16. When the first filter element 21 is slidably mounted on the slide rail 16, the rack 172 and the gear 171 mesh with each other.

[0055] Reference Figure 1 and Figure 6When it is necessary to replace the old first filter element 21 in the housing 1, the switch door 14 is opened, the new first filter element 21 is slidably connected to the idle slide rail 16, and the new first filter element 21 is pushed into the housing 1. The rack 172 on the new first filter element 21 meshes with the gear 171 to drive the gear 171 to rotate. The gear 171 drives the old first filter element 21 to move out of the housing 1 through another rack 172, so that the old first filter element 21 can be taken out of the housing 1 for easy replacement, thus improving the replacement efficiency.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
