Description
Technical Field
[0001] This utility model relates to the field of waste gas purification boxes, specifically a waste gas treatment residue separation device. Background Technology
[0002] The exhaust gas purification box is a highly efficient device for treating industrial and laboratory exhaust gases. It integrates dust filtration, residue removal, and odor adsorption functions. It uses high-efficiency filtration systems such as pre-filters and activated carbon filters to remove solid particles and tiny pollutants from the exhaust gas, treats residues through specific filtration or separation technologies, and effectively removes odor molecules by means of activated carbon adsorption and chemical adsorption principles.
[0003] Currently, although waste gas treatment and purification devices have the functions of filtering dust, filter residue, and odor adsorption, there are still obvious shortcomings in practical applications. Traditional devices rely on fixed filter layers for residue separation. When faced with situations where the residue content in waste gas varies greatly, their processing flexibility and applicability are particularly insufficient. In view of this, there is an urgent need to design a mechanism that can flexibly adjust the filtration efficiency of the filter layer, so that the purification device can quickly adjust its working state according to different waste gas characteristics, thereby significantly improving its ease of use and overall treatment efficiency. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a waste gas treatment residue separation device to solve the technical problem that when using a fixed filter layer to separate waste gas residue, the device has poor flexibility and low applicability when treating waste gas containing different levels of residue.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment residue separation device, including a waste gas adsorption box and a dust filter box. The dust filter box has a dust filter mechanism on its inner side. The dust filter mechanism includes two sets of mounting mesh frames. Each set of the dust filter mechanism includes two mounting mesh frames. The two mounting mesh frames in each set are mirror-symmetrical. The two sets of mounting mesh frames are movably connected. One side of the two mounting mesh frames in each set is movably connected by a connector. A filter layer is detachably installed on the inner side of the mounting mesh frame via a slide rail. One side of the two sets of filter layers is connected to a linear drive component.
[0006] By adopting the above technical solution, the dust filtration mechanism realizes dynamic filtration and adjustment of waste gas residue. The two sets of mirror-symmetrical installation frames are connected in an active manner, and the filter layer is moved by a linear drive component. The filter layer spacing can be flexibly adjusted, which significantly improves the adaptability of the device to waste gas with different residue concentrations. It breaks through the limitations of traditional fixed filter layers and realizes real-time control of filtration density through mechanical transmission, ensuring efficient interception when treating high-concentration residues and reducing energy consumption when treating low-concentration residues, thus forming an intelligent graded treatment mechanism.
[0007] Furthermore, the top view of the two sets of mounting frames is an "M" shaped structure, with the side of the mounting frame away from the linear drive component hinged to the dust filter box, and the movement of the mounting frame is restricted by the inner plate of the dust filter box.
[0008] By adopting the above technical solution, the top view structure of the installed mesh frame effectively increases the filtration area. The wavy layout extends the exhaust gas flow path and enhances the residue separation efficiency. The side away from the linear drive component is hinged to the dust filter box, which not only ensures the flexibility of the mesh frame's movement but also restricts its range of motion through the inner side plate.
[0009] Furthermore, the linear drive unit includes a pneumatic adjustment unit and / or an electric push rod unit, and the telescopic end is hinged to the corresponding mounting frame.
[0010] By adopting the above technical solutions, the pneumatic drive has a rapid response and is suitable for short-term high-frequency adjustment scenarios; the electric actuator has precise position control capabilities and is suitable for working conditions that require constant filtration parameters. The two working together not only broaden the applicable environment of the equipment, but also improve the system reliability through redundant design.
[0011] Furthermore, several activated carbon adsorption blocks are installed inside the waste gas adsorption box, and a movable door is provided on the front side of the waste gas adsorption box for replacing the activated carbon blocks.
[0012] By adopting the above technical solution, the graded adsorption of VOCs molecules is achieved through the gradient setting of the pore structure. The combination of activated carbon particles of different sizes not only ensures the rapid capture of large molecular pollutants, but also achieves the deep removal of small molecular odor substances through the microporous structure.
[0013] Furthermore, the exhaust gas adsorption box and the dust filter box are connected, and the front of the dust filter box is provided with a movable door for replacing the filter layer.
[0014] By adopting the above technical solution, a complete treatment chain is constructed. The exhaust gas undergoes three stages of treatment in sequence: coarse filtration, fine filtration, and adsorption. The process is compact and efficient. The movable door on the front of the dust filter box can maintain a negative pressure environment inside the box when replacing the filter layer, preventing the leakage of toxic gases.
[0015] Furthermore, an air inlet is provided on one side of the dust filter box, and an air outlet is provided on one side of the exhaust gas adsorption box.
[0016] By adopting the above technical solutions, the symmetrical layout optimizes the gas flow field distribution and improves the waste gas collection efficiency. The vortex elimination device configured at the outlet effectively reduces the turbulence disturbance of clean gas, allowing the device to be seamlessly integrated into the existing industrial ventilation system.
[0017] Furthermore, a wind pressure sensor and a VOC concentration sensor are installed at the air inlet, and the signals from the two sensors are fused together using a PID algorithm to generate a drive command.
[0018] By adopting the above technical solution, the wind pressure sensor and the VOC concentration sensor constitute a multi-dimensional sensing system. The nonlinear fusion of sensor data is achieved through the PID algorithm, and the output command can synchronously control the displacement of the linear drive and the ventilation volume of the activated carbon adsorption module. This closed-loop control strategy enables the device to have adaptive adjustment capability and can complete parameter correction in a short time when the exhaust gas concentration changes abruptly.
[0019] In summary, the present invention has the following main advantages:
[0020] This invention utilizes a dust filtration mechanism that allows for real-time adjustment of the filter layer spacing under the action of a linear drive. When treating high-concentration residual exhaust gas, the drive pushes the mesh frame to tighten, increasing the filter layer density and enhancing the interlayer compaction, effectively intercepting large particles of residue and enhancing the adsorption capacity of fine particles. When treating low-concentration exhaust gas, the mesh frame separates to expand the spacing, reducing the filter layer density and decreasing airflow resistance, thereby optimizing energy consumption.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0027] In this embodiment:
[0028] Waste gas treatment residue separation device, such as Figure 1-4As shown, the system includes a waste gas adsorption box 1 and a dust filter box 2. A dust filter mechanism 4 is installed inside the dust filter box 2. The dust filter mechanism 4 includes two sets of mounting frames 401. Each set of the dust filter mechanism 4 contains two mounting frames 401, which are mirror-symmetrical. The two sets of mounting frames 401 are movably connected. One side of the two mounting frames 401 in each set is movably connected via a connector 404. A filter layer 402 is detachably installed on the inner side of the mounting frames 401 via a slide rail 405. One side of the two sets of filter layers 402 is connected to a linear drive component 403. The dust filter mechanism 4 achieves dynamic filtration and adjustment of waste gas residue. The mirror-symmetrical mounting frame 401 adopts a movable connection method, which, together with the linear drive component 403, drives the filter layer 402 to move. The spacing between the filter layers can be flexibly adjusted, which significantly improves the adaptability of the device to waste gas with different residue concentrations. It breaks through the limitations of traditional fixed filter layers and realizes real-time control of filtration density through mechanical transmission. This ensures high-efficiency interception when treating high-concentration residues and reduces energy consumption when treating low-concentration residues, forming an intelligent graded treatment mechanism. At the same time, the detachable mounting structure of the slide rail 405 facilitates quick replacement of the filter layer 402, reduces maintenance costs, further enhances the expandability of the equipment, and provides technical support for multi-scenario industrial applications.
[0029] See Figure 1 , Figure 2 , Figure 3 The top view of the two sets of mounting mesh frames 401 is an "M" shaped structure. The side of the mounting mesh frame 401 away from the linear drive component 403 is hinged to the dust filter box 2, and the movement of the mounting mesh frame 401 is restricted by the inner plate of the dust filter box 2. The top view structure of the mounting mesh frame 401 effectively increases the filtration area. The wavy layout extends the exhaust gas flow path and enhances the residue separation efficiency. The hinged connection of the side away from the linear drive component 403 to the dust filter box 2 ensures the flexibility of the mesh frame movement, while the inner plate restricts its range of movement, avoiding structural instability caused by excessive displacement. This constrained hinge design maintains the geometric stability of the mesh frame during dynamic adjustment, ensuring that the filter layer 402 is always tightly fitted and preventing exhaust gas short circuit.
[0030] See Figure 1 , Figure 2 , Figure 3The linear drive unit 403 includes a pneumatic adjustment unit and / or an electric actuator unit, and its telescopic end is hinged to the corresponding mounting frame 401. The pneumatic drive has a rapid response and is suitable for short-term, high-frequency adjustment scenarios. The electric actuator has precise position control capabilities and is suitable for working conditions that require constant filtration parameters. The two work together to not only broaden the applicable environment of the equipment, but also improve the system reliability through redundant design. At the same time, the hinged connection between the telescopic end and the mounting frame 401 achieves lever arm optimization, which can obtain a larger adjustment stroke under the same driving force. With the control command output by the PID algorithm, the compaction of the filter layer 402 can be precisely controlled.
[0031] See Figure 1 , Figure 2 , Figure 3 The inner side of the exhaust gas adsorption box 1 is equipped with several activated carbon adsorption blocks. The front side of the exhaust gas adsorption box 1 is equipped with a movable door for replacing the activated carbon blocks. The graded adsorption of VOCs molecules is achieved through the gradient setting of the pore structure. The combination of activated carbon particles of different sizes not only ensures the rapid capture of large molecular pollutants, but also achieves the deep removal of small molecular odor substances through the microporous structure. The movable door on the front side adopts a quick locking mechanism, which can complete the replacement of a single adsorption module in a short time, significantly shortening the maintenance time.
[0032] See Figure 1 , Figure 2 , Figure 3 The exhaust gas adsorption box 1 and the dust filter box 2 are connected. The front of the dust filter box 2 is equipped with a movable door for replacing the filter layer 402, thus constructing a complete treatment chain. The exhaust gas passes through three stages of treatment: coarse filtration, fine filtration, and adsorption. The process is compact and efficient. The movable door on the front of the dust filter box 2 can maintain a negative pressure environment inside the box when replacing the filter layer 402 to prevent the leakage of toxic gases. At the same time, the independent maintenance channel of the two boxes improves the purification level of the exhaust gas. Activated carbon replacement and filter layer cleaning can be carried out simultaneously, which significantly improves the continuous operation capability of the industrial site.
[0033] See Figure 1 , Figure 2 , Figure 3 The dust filter box 2 has an air inlet 301 on one side and an air outlet 302 on one side of the exhaust gas adsorption box 1. The symmetrical layout optimizes the gas flow field distribution and improves the exhaust gas collection efficiency. The eddy current elimination device configured in the air outlet 302 effectively reduces the turbulence disturbance of the clean gas, allowing the device to be seamlessly connected to the existing industrial ventilation system. At the same time, the parallel air duct structure of the double box reduces the pressure loss compared with the traditional device under the rated air volume, which significantly reduces the energy consumption of the supporting fan.
[0034] See Figure 1 , Figure 2 , Figure 3A wind pressure sensor and a VOC concentration sensor are installed at the air inlet 301. The signals from both sensors are fused using a PID algorithm to generate a drive command. The wind pressure sensor and the VOC concentration sensor constitute a multi-dimensional sensing system. The PID algorithm enables nonlinear fusion of sensor data, and the output command can synchronously control the displacement of the linear drive 403 and the ventilation volume of the activated carbon adsorption module. This closed-loop control strategy enables the device to have adaptive adjustment capabilities. When the exhaust gas concentration changes abruptly, the parameters can be corrected in a short time. At the same time, the sensor data is connected to the industrial Internet of Things platform through a wireless transmission module, supporting remote monitoring and predictive maintenance.
[0035] The implementation principle of this embodiment is as follows: the exhaust gas first enters through the air inlet 301 of the dust filter box 2. The built-in wind pressure sensor and VOC concentration sensor detect the exhaust gas parameters in real time. The control command is generated by the PID algorithm. The dust filter mechanism 4 is the core component. It consists of two sets of multiple installation mesh frames 401 in an "M" shape, forming a mirror symmetrical layout. The mesh frames are movably connected by connectors 404. The filter layer 402 installed on the inner slide rail 405 can dynamically adjust the spacing under the drive of the linear drive component 403, so as to adapt to the exhaust gas treatment requirements with different residue contents. At the same time, the compaction between adjacent filter layers 402 is adjusted, the overall density of the filter layer 402 is adjusted, and the airflow resistance is adjusted, so as to adapt to the purification treatment operation of various exhaust gases. The gas after dust filtration enters the exhaust gas adsorption box 1. The activated carbon adsorption block installed inside further adsorbs odors and harmful gases. Finally, the purified gas is discharged from the air outlet 302.
