Description

Technical Field

[0001] This utility model mainly relates to the technical field of industrial VOC waste gas treatment equipment, specifically an industrial electrical automation device. Background Technology

[0002] Electrical automation equipment is a type of equipment that combines electrical engineering with automation technology. It can automatically monitor, control, regulate, and protect various electrical parameters of power systems, electrical equipment, and production processes to achieve automation of production processes, improve production efficiency, ensure product quality, reduce labor intensity, and ensure production safety. Industrial VOC waste gas treatment equipment is a common type of electrical automation equipment.

[0003] Industrial VOC waste gas treatment equipment includes pretreatment devices (such as filters), adsorbers (containing adsorbents such as activated carbon or zeolite), desorption devices (heating systems, etc.), catalytic burners, heat exchangers, fans, and valves. Organic waste gas is first pretreated to remove dust and other impurities, then enters the adsorber. The VOCs in the waste gas are adsorbed by the adsorbent, and the purified air is discharged. As adsorption proceeds, once the adsorbent is saturated, it desorbs VOCs through contact with high-temperature hot air, forming concentrated waste gas. Simultaneously, the adsorption bed is regenerated. The concentrated waste gas then enters the catalytic burner, where, under the action of the catalyst, it is purified at 200°C. An oxidation reaction occurs at 450℃, producing carbon dioxide and water that meet emission standards. The heat from the reaction can be recovered and reused through a heat exchanger. The adsorber consists of a shell, lining, adsorbent, packing support structure, inlet and outlet ports, and a heat exchanger. The internal packing support structure is currently commonly made of grid plates or perforated plates. The open area ratio of perforated plates is usually limited, which reduces the windward area and increases the resistance when gas passes through, affecting the adsorbent's processing capacity and efficiency. Moreover, the pore size of perforated plates is relatively small, which can easily cause blockage when the treated waste gas contains particulate pollutants or sticky substances, hindering gas flow, reducing the adsorption effect, and increasing the maintenance cost and frequency of the equipment. The grid plate has a relatively open structure, which is conducive to gas flow, but the uniformity of the support for the adsorbent may not be as good as that of the perforated plate. During the filling and use of the adsorbent, local accumulation or uneven distribution of the adsorbent may occur, affecting the consistency of the adsorption effect. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. Specifically, this utility model mainly provides an industrial electrical automation device to solve the technical problem mentioned in the background: the existing packing support structure in the current adsorber is mostly a grid plate or a perforated plate. These structural plates are greatly affected by themselves, resulting in poor gas flow and poor waste gas treatment capacity.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An industrial electrical automation device includes a pretreatment device, a combustion catalyst, a heat exchanger, an adsorption device, and an electrical control box. The adsorption device includes a base, on which a housing is mounted. The housing includes an inner cavity, a front cover, and a rear cover. The front cover and the rear cover are located at two openings of the inner cavity, respectively. Two adsorption components are disposed in the inner cavity, arranged vertically. Each adsorption component includes multiple equally spaced linearly arranged corrugated structural plates. A molecular sieve layer and an activated carbon layer are respectively disposed on the upper and lower sides of each corrugated structural plate.

[0007] Furthermore, each of the adsorption components includes two support frames, which are distributed in parallel on both sides of the inner wall of the cavity.

[0008] Furthermore, each of the horizontal portions of the support frame is provided with mounting holes.

[0009] Furthermore, each of the vertical portions of the support frame is provided with multiple positioning slots, which are linearly distributed at equal intervals. Each positioning slot is engaged with a positioning block, which is located at the two side edges of the corrugated structure plate.

[0010] Furthermore, each of the two edges on the upper side of the wave structure plate is provided with a first limiting groove, and the two first limiting grooves cooperate with the two sides of the corresponding molecular sieve layer.

[0011] Furthermore, each of the two edges on the lower side of the wave structure plate is provided with a second limiting groove, and the two second limiting grooves cooperate with the two sides of the corresponding activated carbon layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes an adsorption device, support frame, positioning slots, a corrugated structure plate, positioning blocks, a molecular sieve layer, and an activated carbon layer to treat industrial VOC waste gas. The unique corrugated shape increases the surface area, expanding the contact area between the adsorbent and the waste gas. Compared to traditional flat plate structures, the corrugated plate allows for more thorough contact between the adsorbent and the waste gas, thereby improving adsorption efficiency and more effectively removing pollutants. The undulating structure guides and disperses the airflow, making the waste gas flow more uniform within the adsorber, helping to avoid airflow short-circuiting or excessively high local flow velocities, allowing the adsorbent to function evenly and improving the overall performance stability of the adsorber. The corrugated plate structure is relatively more flexible and stronger, better maintaining its shape when bearing the weight of the adsorbent and the impact of airflow, reducing the possibility of deformation and damage. Compared to porous plates or grid plates, the corrugated plate is less prone to adsorbent leakage or uneven distribution due to structural problems during long-term use. Furthermore, the first and second limiting slots facilitate the replacement of the molecular sieve layer and activated carbon layer, making operation simple and practical.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0026] Please refer to the appendix carefully. Figure 1-7An industrial electrical automation device includes a pretreatment device 1, a combustion catalyst 2, a heat exchanger 3, an adsorption device 4, and an electrical control box 5. The adsorption device 4 includes a base 41, on which a housing 42 is mounted. The housing 42 includes an inner cavity 421, a front cover 422, and a rear cover 423. The front cover 422 and the rear cover 423 are located at two openings of the inner cavity 421, respectively. Two adsorption components 6 are arranged vertically within the inner cavity 421. Each adsorption component 6 includes multiple equally spaced linearly arranged corrugated structural plates 64. Each corrugated structural plate 64 has a molecular sieve layer 65 and an activated carbon layer 66 on its upper and lower sides, respectively. The molecular sieve layer 65 is mainly used to remove organic hydrocarbons, halogenated hydrocarbons, alcohols, and aldehydes and ketones from waste gas. The activated carbon has a rich microporous structure and a large specific surface area, and is effective against non-polar or weakly polar VOCs. It has a strong adsorption capacity, such as alkanes like n-hexane and cyclohexane, and aromatic hydrocarbons like benzene, toluene, and xylene. Activated carbon adsorbs these molecules on its surface and in its pores through van der Waals forces, thereby achieving effective removal of them.

[0027] The above structure enables the treatment of industrial VOC waste gas. The unique wave shape increases the surface area, thus increasing the contact area between the adsorbent and the waste gas. Compared with the traditional flat plate structure, the wave plate allows the adsorbent to come into more full contact with the waste gas, thereby improving adsorption efficiency and removing pollutants from the waste gas more effectively. The undulating wave structure can guide and disperse the airflow, making the flow of waste gas in the adsorber more uniform. This helps to avoid airflow short-circuiting or excessively high local flow velocities, allowing the adsorbent to work evenly and improving the overall performance stability of the adsorber. The structure of the wave plate is relatively more flexible and stronger. When bearing the weight of the adsorbent and the impact of airflow, it can better maintain its shape and reduce the possibility of deformation and damage. Compared with porous plates or grid plates, the wave plate is less likely to experience adsorbent leakage or uneven distribution due to structural problems during long-term use.

[0028] Please refer to the appendix carefully. Figure 5 and attached Figure 6Each adsorption component 6 includes two support frames 61, which are distributed parallel to each other on both sides of the inner wall of the inner cavity 421. Each support frame 61 has mounting holes 63 on its horizontal portion. The support frames 61 provide support for the corrugated structure plate 64, ensuring a stable working environment. Each support frame 61 also has multiple positioning slots 62 on its vertical portion, which are linearly distributed at equal intervals. Each positioning slot 62 engages with a positioning block 643, which is positioned at the two edges of the corrugated structure plate 64. The cooperation between the positioning blocks 643 and the positioning slots 62 enables a detachable connection between the corrugated structure plate 64 and the support frame 61. To facilitate later maintenance and replacement, each of the corrugated structural plates 64 has a first limiting groove 641 at each of its two upper edges. The two first limiting grooves 641 cooperate with the two sides of the corresponding molecular sieve layer 65. Through the first limiting grooves 641, the two sides of the molecular sieve layer 65 are limited, thereby installing the molecular sieve layer 65 onto the corrugated structural plate 64. Each of the corrugated structural plates 64 has a second limiting groove 642 at each of its two lower edges. The two second limiting grooves 642 cooperate with the two sides of the corresponding activated carbon layer 66. Through the second limiting grooves 642, the two sides of the activated carbon layer 66 are limited, thereby installing the activated carbon layer 66 onto the corrugated structural plate 64.

[0029] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
