Description

Technical Field

[0001] This application relates to the field of waste gas treatment technology, and in particular to a VOC waste gas treatment device. Background Technology

[0002] As we all know, VOC (volatile organic compounds) treatment is the key to atmospheric environmental governance. After years of development and improvement, VOC treatment technology can basically meet the needs of various industries and various waste gas treatments. However, for the treatment of certain special forms of organic waste gas, existing technologies still have many defects and shortcomings.

[0003] Currently, in related technologies, a search reveals that a utility model with patent publication number CN219128644U discloses a VOC exhaust gas treatment device, including a housing. A sealing door is movably installed on one side of the front of the housing, and a discharge port is movably provided on the lower side of the other side of the front of the housing. Three loading ports are equidistantly arranged on the top of the housing. Multiple detachable filter screens are installed inside the housing from left to right, and a discharge box is fixedly installed on the right side of the bottom inside the housing.

[0004] Regarding the aforementioned technologies, although dry filtration of exhaust gas using filters followed by VOC adsorption with activated carbon achieves a certain degree of exhaust gas purification, the applicant has found that existing filters typically only remove a small amount of particulate matter from the exhaust gas. In actual industrial production, VOC exhaust gas often contains not only simple dust but may also include impurities such as oil mist, sticky particles, and fine dust. For these complex impurities, the filtration capacity of existing filters is insufficient to meet the usage requirements, resulting in certain limitations in their application. Furthermore, the limitations in the filtration capacity of filters not only affect the purification efficiency and operational stability of VOC exhaust gas treatment devices but also increase equipment maintenance costs, making them impractical.

[0005] Therefore, it is necessary to propose a VOC waste gas treatment device. Utility Model Content

[0006] The purpose of this invention is to provide a VOC waste gas treatment device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A VOC exhaust gas treatment device, comprising:

[0009] Base;

[0010] Two main chambers are symmetrically arranged on the base, and each main chamber is detachably connected to a mounting plate. Each mounting plate is detachably connected to a coarse filter and a high-efficiency HEPA filter, respectively.

[0011] The bin cover is adapted to the main bin body and is detachably connected to the main bin body;

[0012] An air intake pipe, which is connected to the main compartment body equipped with a coarse filter screen;

[0013] The medium-efficiency oil mist separator body is mounted on the base via a connecting assembly, and both the input and output ends of the medium-efficiency oil mist separator are connected to the two main chambers via connecting pipes.

[0014] The output pipe is connected to the main chamber body equipped with a high-efficiency HEPA filter.

[0015] A movable component, which is disposed within the base, is used to drive the base to move accordingly.

[0016] As a further embodiment of this utility model: the connecting assembly includes three connecting plates, all three connecting plates are symmetrically arranged on the outer wall of the medium-efficiency oil mist separator body, and a support column is fixedly connected to the bottom of the connecting plate, a support base is fixedly connected to the bottom of the support column, and the support base is fixedly connected to the base.

[0017] As a further improvement of this utility model: the movable component includes four pillars, all of which are set in the base through connecting grooves, and the other end of the pillars is detachably connected to a self-locking universal wheel.

[0018] As a further improvement of this utility model: two strip blocks are fixedly connected to the mounting plate, and the strip blocks are detachably connected to the main compartment body by two mounting bolts.

[0019] As a further improvement of this utility model: two support plates are fixedly connected to the base, and a first handle is provided between the two support plates. The first handle is covered with an anti-slip rubber sleeve.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By incorporating a movable component, the base can be moved to a suitable position through the cooperation of multiple support pillars and self-locking casters. A multi-stage filtration system is then formed through the collaboration of a two-stage main chamber and a medium-efficiency oil mist separator. A coarse filter first removes large particulate impurities from the exhaust gas, while the medium-efficiency oil mist separator efficiently separates oil mist from sticky particles. Finally, a high-efficiency HEPA filter deeply purifies fine dust, significantly improving VOC exhaust gas purification efficiency and adaptability. The connecting plate, support pillars, and support base of the connecting component provide stable support for the oil mist separator. Its overall structure is relatively simple. Compared to existing technologies, its multi-stage filtration, convenient maintenance, and flexible movement effectively improve the exhaust gas treatment effect and equipment operational stability, thereby reducing maintenance costs. It boasts strong comprehensive practicality, meets complex VOC exhaust gas treatment needs, and is conducive to widespread application. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-4 In this embodiment of the present invention, a VOC waste gas treatment device includes:

[0031] Base 1;

[0032] Two main chambers 2 are symmetrically arranged on the base 1, and each main chamber 2 can be detachably connected to a mounting plate 3. Each mounting plate 3 can be detachably connected to a coarse filter 4 and a high-efficiency HEPA filter 5.

[0033] The compartment cover 6 is adapted to the main compartment body 2 and can be detachably connected to the main compartment body 2.

[0034] The air intake pipe 7 is connected to the main compartment 2, which is equipped with a coarse filter screen 4.

[0035] The medium-efficiency oil mist separator body 8 is mounted on the base 1 via a connecting component, and both the input and output ends of the medium-efficiency oil mist separator are connected to the two main chambers 2 via connecting pipes 9.

[0036] The output pipe 10 is connected to the main chamber 2, which is equipped with a high-efficiency HEPA filter 5.

[0037] A movable component is disposed within the base 1 and is used to move the base 1 accordingly.

[0038] In operation, this VOC exhaust gas treatment device adjusts the device position by moving the components, pushing the device to roll the self-locking casters 15 to the designated working area, locking the casters for fixation, and then fixing the mounting plates 3 containing the coarse filter 4 and the high-efficiency HEPA filter to the two main chambers 2 respectively using the mounting bolts 17. After closing the chamber cover 6, the air inlet pipe 7 is connected to the exhaust gas source, and the medium-efficiency oil mist separator body 8 is started. The exhaust gas enters the first main chamber 2 through the air inlet pipe 7, where the coarse filter 4 first filters out large particulate impurities; then it enters the medium-efficiency oil mist separator body 8 through the connecting pipe 9, separating oil mist and sticky particles; the purified exhaust gas enters the second main chamber 2 through another connecting pipe 9, where the high-efficiency HEPA filter deeply filters fine dust, and finally the clean gas is discharged from the output pipe 10.

[0039] exist Figure 1-3 In the middle: the connecting assembly includes three connecting plates 11, which are symmetrically arranged on the outer wall of the medium-efficiency oil mist separator body 8. The bottom of the connecting plate 11 is fixedly connected to a support column 12, and the bottom of the support column 12 is fixedly connected to a support seat 13, which is fixedly connected to the base 1.

[0040] This VOC exhaust gas treatment device, through this structural arrangement, forms a balanced support structure with three symmetrically distributed connecting plates 11 and support columns 12, which firmly fixes the main body 8 of the medium-efficiency oil mist separator on the base 1, ensuring that it is not affected by airflow impact or equipment vibration during exhaust gas treatment; the support base 13 increases the contact area with the base 1, further improving the connection stability, preventing the oil mist separator from shifting or shaking during operation, and ensuring the sealing of the gas circuit connection and treatment efficiency.

[0041] exist Figure 1-4 The moving component includes four pillars 14, all of which are set in the base 1 through connecting slots, and the other end of each pillar 14 is detachably connected to a self-locking caster wheel 15.

[0042] This VOC exhaust gas treatment device, through this structural design, allows the four pillars 14 to work together with the self-locking casters 15 to enable flexible movement of the equipment, making it easy to adjust the installation position according to operational needs; the self-locking function of the casters can lock the moving parts after the equipment is in place, preventing accidental slippage during operation and improving operational safety.

[0043] exist Figure 1-4 In the middle: two strip blocks 16 are fixedly connected to the mounting plate 3. The strip blocks 16 are detachably connected to the main compartment 2 by two mounting bolts 17. Two support plates 18 are fixedly connected to the base 1. A first handle 19 is provided between the two support plates 18. The outside of the first handle 19 is fixedly fitted with an anti-slip rubber sleeve 20. Two strip handles 21 are fixedly connected to the compartment cover 6. The outside of the two strip handles 21 is fitted with an anti-slip sleeve 22.

[0044] It should also be noted that the cooperation between the strip block 16 and the mounting bolt 17 enables the detachable connection of the mounting plate 3 and the filter screen, which facilitates the flexible replacement of different specifications of filter screens according to the composition of exhaust gas, thereby improving the adaptability of the equipment; the first handle 19 and the anti-slip rubber sleeve 20 provide convenient gripping points for moving the equipment and enhance the stability of force application; the strip handle 21 and the anti-slip sleeve 22 facilitate the opening and closing of the cover 6 and prevent hand slippage. The overall structure takes into account both the convenience of disassembly and assembly and the safety of operation.

[0045] In this embodiment, the coarse filter 4, the high-efficiency HEPA filter 5, and the medium-efficiency oil mist separator body 8 are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, so we will not go into detail here. The medium-efficiency oil mist separator body 8 is equipped with a matching control switch. The installation position of the control switch is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0046] The implementation principle of a VOC exhaust gas treatment device in this application embodiment is as follows: First, through the cooperation of the support column 14 and the self-locking casters 15, the operator holds the first handle 19 on the base 1 and pushes the device to make the four self-locking casters 15 roll to the working area, locking the casters to prevent the device from sliding. Then, the mounting plate 3, which is equipped with the coarse filter 4 and the high-efficiency HEPA filter, is fixed in the two main chambers 2 respectively by the mounting bolts 17. The cooperation between the strip block 16 and the mounting bolts 17 ensures that the filter is firmly installed and fits tightly with the chamber. After closing the chamber cover 6, connect the air inlet pipe 7 to the exhaust gas source, so that the medium-efficiency oil mist separator body 8 forms a complete air path with the two main chambers 2 through the connecting pipe 9. After starting the equipment, VOC exhaust gas enters the first main chamber 2 through the air inlet pipe 7. The coarse filter screen 4 first filters out large particulate impurities; it enters the medium-efficiency oil mist separator body 8 through the connecting pipe 9, separating oil mist and sticky particulate matter; the purified exhaust gas enters the second main chamber 2 through another connecting pipe 9, where the high-efficiency HEPA filter deeply filters fine dust, and finally the clean gas is discharged from the output pipe 10.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
