Description

Technical Field

[0001] The present application relates to the technical field of waste gas treatment, and in particular to a fiberboard drying waste gas treatment device. Background Art

[0002] Fiberboard is a man-made board, mainly made of plant fibers and adhesives. During the drying process of fiberboard, a large amount of harmful waste gas is usually generated, which mainly contains formaldehyde, phenols, fiber dust, nitrogen oxides, sulfur dioxide, water vapor and other pollutants. In order to avoid these pollutants from causing harm to the atmospheric environment, the waste gas needs to be treated during the drying process of fiberboard.

[0003] At present, the treatment of fiberboard drying exhaust gas is generally completed by dry filters or wet dust collectors. Among them, dry filters use dry filter materials to capture solid particles and impurities in liquids or gases to achieve the purpose of purification; while wet dust collectors are equipment that uses water to capture dust in the air. When dust-laden gas passes through the water body, the dust collides with the water body and adheres to the water body, and then is separated from the gas by gravity sedimentation or other treatment methods.

[0004] Referring to the Chinese patent document with announcement number CN118304727B and announcement date September 20, 2024, entitled A Noise Reduction Industrial Wet Fume Purifier, by setting a baffle assembly and a buffer assembly, the flue gas will be effectively dispersed and fully contacted with the aqueous solution, thereby achieving the separation of large-particle fume particles.

[0005] With regard to the above technical solution, when the exhaust gas treatment effect is improved by increasing the contact path between the flue gas and the water body through baffles, since the multi-layer baffles are often fixedly distributed on the silo wall in an alternating interval, the fluid flow rate at the angle between the baffle and the silo wall is relatively slow. As time goes by, impurities are prone to precipitate and accumulate in the water body at the angle between the baffle and the silo wall, causing the water body here to tend to be saturated and affecting the water body's adsorption effect on impurities in the exhaust gas. Summary of the invention

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 5 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0033] Reference Figure 1 and Figure 2 This embodiment provides a fiberboard drying waste gas treatment device, including a housing 1 and a flow guide cavity 11, a plurality of baffles 12, a negative pressure cleaning component, a filter press component, and a flow channel adjustment component 4. The air inlet pipe 13 arranged at the bottom of the housing 1 and the exhaust pipe 14 arranged at the top are both connected to the flow guide cavity 11, and the plurality of baffles 12 are evenly arranged inside the flow guide cavity 11, and the baffles 12 located on the left side of the flow guide cavity 11 and the baffles 12 located on the right side of the flow guide cavity 11 are arranged one by one.

[0034] Among them, refer to Figure 2 The negative pressure cleaning assembly includes two negative pressure chambers 2 and multiple slag discharge ports 21. The two negative pressure chambers 2 are respectively arranged on the left and right sides of the housing 1, and the bottom ends of the two negative pressure chambers 2 are connected to the guide chamber 11, and the multiple slag discharge ports 21 are all opened on the inner wall of the guide chamber 11 and correspond to the baffles 12 one by one, and the slag discharge ports 21 are all connected to the negative pressure chamber 2.

[0035] Among them, refer to Figure 3 and Figure 4 The filter press assembly includes a filter press chamber 3, a cylinder 31, a filter press plate 32, filter press holes 33 and a cover plate 34. The filter press chamber 3 is arranged at the bottom of the flow guide chamber 11, the cylinder 31 is arranged at the bottom of the housing 1, the filter press plate 32 is fixedly connected to the execution end of the cylinder 31 and vertically slidably connected inside the filter press chamber 3, the filter press plate 32 is arranged in an "n" shape, the filter press holes 33 are evenly opened at the top of the filter press chamber 3 and communicated with the flow guide chamber 11, and the cover plate 34 is hinged at the bottom of the flow guide chamber 11 through a torsion spring and can block the filter press holes 33.

[0036] Among them, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The flow channel regulating assembly 4 includes a plurality of flow guide ports 41, two baffles 42 and a hydraulic cylinder 43. The plurality of flow guide ports 41 are all provided on the inner wall of the filter press chamber 3 and communicated with the flow guide chamber 11. The two baffles 42 are slidably connected inside the flow guide chamber 11 and matched with the flow guide ports 41. The hydraulic cylinder 43 is provided on the housing 1 and is used to drive the baffle 42 to block the flow guide ports 41 or release the blocking state of the baffle 42 on the flow guide ports 41.

[0037] When the dry waste gas of the fiberboard is passed into the guide chamber 11 through the air inlet pipe 13, the waste gas will be mixed with the water body supplied in advance inside the guide chamber 11, and then the waste gas will move upward along the gaps between the multiple baffles 12 and be discharged from the exhaust pipe 14, and the impurities in the waste gas will be captured and removed by the water body, so as to complete the treatment of the dry waste gas of the fiberboard. With the increase of the use time, when the cylinder 31 drives the filter plate 32 to move downward, the hydraulic cylinder 43 makes the baffle 42 and the guide port 41 misaligned. At this time, the impurities gathered at the angle between the baffle 12 and the guide chamber 11 will enter the filter chamber 3 through the slag discharge port 21, the negative pressure chamber 2 and the guide port 41 in turn under the negative pressure generated inside the filter chamber 3, thereby reducing the probability of impurities gathering at the angle between the baffle 12 and the guide chamber 11. When the cylinder 31 moves upward to drive the filter plate 32 to perform the filter pressing action, the hydraulic cylinder 43 operates to make the baffle 42 block the diversion port 41, and the water inside the filter press chamber 3 will be ejected from the filter press hole 33 and push the cover plate 34 open, so that the water without impurities after the filter press can re-enter the diversion chamber 11 for circulation, thereby enhancing the fluidity of the water inside the diversion chamber 11, and after the cover plate 34 is completely pushed open, the jet-like water produced by the filter press can be more effectively combined with the exhaust gas.

[0038] Reference Figure 2 , Figure 3 and Figure 5, the baffles 12 are all hingedly arranged inside the guide cavity 11, and a linkage 5 for adjusting the tilt state of the baffles 12 is arranged between the filter press plate 32 and the baffles 12. The linkage 5 includes three transmission rods 51, the middle transmission rod 51 is hinged on the inner wall of the guide cavity 11, the transmission rods 51 on the upper and lower sides are vertically slidably connected inside the guide cavity 11 and are connected to the corresponding bar holes opened on the middle transmission rod 51 in a hinged manner, the bottom end of the lower transmission rod 51 is fixedly connected to the filter press plate 32, and the bar grooves opened on each baffle 12 are connected to the upper transmission rod 51 in a hinged manner. The Z-shaped connecting rod group composed of the three transmission rods 51 can drive the baffles 12 to swing downward when the filter press plate 32 rises or drive the baffles 12 to swing upward when the filter press plate 32 falls.

[0039] When the filter press plate 32 rises to perform the filtering action, through the cooperation of the linkage part 5, all the baffles 12 will be adjusted to be tilted from bottom to top toward the direction of the corresponding slag discharge port 21, so that the circulating water moving upward after the filtration can pass through the angle between the baffle plate 12 and the guide cavity 11 and flush the impurities that may exist there, further reducing the possibility of impurities gathering at the angle between the baffle plate 12 and the guide cavity 11.

[0040] Reference Figure 1 and Figure 4 The top of the filter press chamber 3 is detachably connected with a slag discharge door 6, and a slag pusher assembly 7 is provided inside the filter press chamber 3 for pushing the waste slag after filtration toward the direction of the slag discharge door 6. The slag pusher assembly 7 includes a slag pusher plate 71 and an adjusting screw 72, the slag pusher plate 71 is longitudinally slidably connected to the top of the filter press chamber 3, the adjusting screw 72 is rotatably connected to the middle of the slag pusher plate 71, and the adjusting screw 72 is threadedly connected to a screw hole provided on the housing 1 and extends to the outside of the housing 1.

[0041] When the filter pressing work is completed, the personnel can open the slag discharge door 6 and then move the slag pusher plate 71 forward by adjusting the screw 72, so as to push the impurities out of the filter pressing chamber 3 from the position where the slag discharge door 6 is located.

[0042] Reference Figure 1 and Figure 3 The air inlet pipe 13 arranged at the bottom of the casing 1 is located above the filter press chamber 3, and a one-way valve 8 is connected in series inside the air inlet pipe 13.

[0043] The implementation principle of a fiberboard drying waste gas treatment device in the embodiment of the present application is:

[0044] When the drying waste gas of the fiberboard passes into the guide chamber 11 through the air inlet pipe 13, the waste gas will be mixed with the water body supplied in advance into the guide chamber 11, and then the waste gas will move upward along the gaps between the multiple baffles 12 and be discharged from the exhaust pipe 14. The water body is used to capture and remove impurities in the waste gas, thereby completing the treatment of the fiberboard drying waste gas.

[0045] As the use time increases, when the cylinder 31 drives the filter press plate 32 to move downward, the hydraulic cylinder 43 causes the baffle 42 to be misaligned with the guide port 41. At this time, the impurities gathered at the angle between the baffle plate 12 and the guide cavity 11 will enter the filter press cavity 3 through the slag discharge port 21, the negative pressure cavity 2 and the guide port 41 in sequence under the action of the negative pressure generated inside the filter press cavity 3.

[0046] When the air cylinder 31 moves upward to drive the filter plate 32 to perform filtering, the hydraulic cylinder 43 operates to make the baffle 42 block the guide port 41, and the water inside the filter chamber 3 will be ejected from the filter hole 33 and push the cover plate 34 open, so that the water without impurities after filtering will re-enter the guide chamber 11 for circulation.

[0047] When the filter pressing work is completed, the personnel can open the slag discharge door 6 and then move the slag pusher plate 71 forward by adjusting the screw 72, so as to push the impurities out of the filter pressing chamber 3 from the position where the slag discharge door 6 is located.

[0048] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0049] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
