Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of industrial waste gas treatment equipment, specifically to a modular waste gas treatment adsorption system. Background Technology
[0002] In industrial production, waste gas treatment is a crucial step in achieving environmental standards, and adsorption is one of the commonly used waste gas treatment technologies. Traditional waste gas treatment adsorption systems typically employ an integrated design. When production scale expands, leading to increased waste gas emissions, large-scale modifications or complete replacement of the original system are required, resulting in poor scalability, long construction periods, and high costs.
[0003] Meanwhile, traditional systems often have complex piping connections and signal lines between control units and functional modules, which not only increases the difficulty of installation, but also makes it easy for control accuracy to decrease due to line interference. Furthermore, maintenance requires checking multiple sets of piping and lines, making the operation cumbersome.
[0004] To address the aforementioned issues, this invention proposes a modular waste gas treatment adsorption system that achieves rapid expansion, convenient installation, and efficient control through standardized design and simplified connection structure. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a modular waste gas treatment adsorption system to solve the problems of difficult expansion, complex installation, cumbersome control circuits, and high maintenance costs of existing waste gas treatment adsorption systems.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A modular waste gas treatment adsorption system includes a desorption module and at least one adsorption module. The desorption module and the adsorption module are respectively equipped with a main control cabinet and a secondary control cabinet. The output end of the adsorption module is connected to the input end of the desorption module through a pipeline. The main control cabinet and the secondary control cabinet are connected through a data transmission medium.
[0008] In a preferred embodiment of this invention, the desorption module can be connected to multiple adsorption modules, and each of the multiple adsorption modules is connected to the desorption module through an independent pipe and a data transmission medium.
[0009] In a preferred embodiment of this invention, the adsorption module is a standardized module, and all adsorption modules have the same structure.
[0010] In a preferred embodiment of this invention, the multiple adsorption modules are arranged in a stacked and / or parallel configuration.
[0011] In a preferred embodiment of this utility model, the connection structure between the adsorption module and the desorption module adopts a standardized interface, and the pipeline and the data transmission medium are both connected by plugging and unplugging through a standardized interface.
[0012] In a preferred embodiment of this utility model, both the main control cabinet and the auxiliary control cabinet adopt PLC.
[0013] In a preferred embodiment of this invention, the data transmission medium is a network cable or an optical fiber.
[0014] In a preferred embodiment of this utility model, the pipe is made of a corrosion-resistant material.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] (1) In this utility model, the structure of desorption module combined with at least one adsorption module can be used to flexibly increase or decrease the number of adsorption modules according to the amount of waste gas emission, without the need to reconstruct the core system; when the production scale is expanded, only the adsorption module needs to be added to match the treatment needs, which solves the problem that traditional integrated system expansion must be carried out on a large scale, and greatly reduces the cost and cycle of capacity upgrade.
[0017] (2) In this utility model, the system realizes the physical and signal connection between modules by combining pipelines and data transmission media, replacing the complex multi-pipeline and multi-line layout of the traditional system. This simplified design not only reduces the complexity of on-site installation, such as reducing the workload of pipeline connection and line layout, but also facilitates later maintenance. When troubleshooting, the pipeline or data link of a single module can be focused, shortening the maintenance time.
[0018] (3) In this utility model, the pipeline is used for the transmission of waste gas / regeneration medium and other substances, and the data transmission medium independently undertakes the role of signal interaction. This system completely separates the material transmission from the control signal transmission, avoids corrosion or interference to the signal line during the material transmission process, and reduces the risk of abnormal material transmission due to line failure, thereby improving the safety of system operation.
[0019] (4) In this utility model, the standardized size design of the adsorption module supports stacking and / or parallel installation, which can be flexibly arranged according to the site space, especially suitable for scenarios with limited factory space, thus improving space utilization. Attached Figure Description
[0020] Figure 1 This is a schematic diagram of the modular waste gas treatment adsorption system in an embodiment of this utility model;
[0021] The system consists of: 1. Desorption module; 2. Adsorption module; 3. Main control cabinet; and 4. Sub-control cabinet. Detailed Implementation
[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0023] like Figure 1 As shown, a modular waste gas treatment adsorption system includes a desorption module 1, which can be connected to at least one adsorption module 2. The desorption module 1 has a built-in main control cabinet 3, and each adsorption module 2 has a built-in auxiliary control cabinet 4. The output end of the adsorption module 2 is connected to the input end of the desorption module 1 through a pipeline for material transfer. The main control cabinet 3 and the auxiliary control cabinet 4 are connected through a data transmission medium for signal transmission.
[0024] Among them, the adsorption module 2 is the purification unit for waste gas treatment. It is mainly responsible for capturing and retaining pollutants in the waste gas. It has built-in adsorption materials (such as activated carbon, molecular sieves, activated carbon fibers, etc.) to adsorb harmful substances in the waste gas onto the surface of the material through physical adsorption or chemical adsorption, so that the treated waste gas meets the emission standards.
[0025] Each adsorption module 2 can independently complete the adsorption process. Its built-in secondary control cabinet 4 can monitor the module's operating status (such as adsorption saturation, temperature, pressure, etc.) in real time, and feed the information back to the main control cabinet 3 of the desorption module 1 through the data transmission medium (network cable or optical fiber) for easy overall system control.
[0026] The desorption module 1 is the regeneration and auxiliary control unit for the adsorbent material. It is mainly responsible for restoring the adsorption capacity of the saturated adsorbent material and coordinating the operation of each adsorption module 2. When the adsorbent material in the adsorption module 2 reaches saturation (can no longer adsorb pollutants), the desorption module 1 desorbs the pollutants from the adsorbent material through specific methods (such as hot air purging, steam heating, inert gas replacement, etc.), realizing the recycling of the material and avoiding the increased costs and waste disposal problems caused by frequent material replacement.
[0027] The main control cabinet 3 built into the desorption module 1 serves as the control core of the system. It sends commands (such as start / stop, adjustment of adsorption intensity, etc.) to the secondary control cabinets 4 of each adsorption module 2 via a data transmission medium, coordinating the operating rhythm of multiple adsorption modules 2 to ensure continuous and stable system operation. For example, when one adsorption module 2 enters the desorption regeneration state, it schedules other adsorption modules 2 to take on more processing load.
[0028] Adsorption module 2 is responsible for purifying the waste gas, while desorption module 1 is responsible for regenerating materials and regulating the system. The material (waste gas to be treated and desorption medium) is transferred through pipelines, and the control signals are exchanged through data transmission media, forming a closed-loop treatment process of adsorption, desorption, regeneration, and re-adsorption. This ensures the continuity of waste gas treatment and improves material utilization and system flexibility.
[0029] This invention adopts a modular design, with the adsorption module 2 having a standardized structure, allowing for flexible increases or decreases in quantity based on the amount of waste gas emitted. When production scales up, only the corresponding number of adsorption modules 2 needs to be added to meet the processing requirements, without needing to modify the original system. This solves the problem of difficult expansion of traditional monolithic systems and significantly reduces the cost of capacity upgrades.
[0030] As described above, adsorption module 2 is a standardized module, and all adsorption modules 2 have the same structure. Desorption module 1 can connect to multiple adsorption modules 2, and each adsorption module 2 is connected to desorption module 1 through independent pipes and data transmission media. The structure, interface, and control logic of all adsorption modules 2 are completely unified, enabling mass production and reducing manufacturing costs. At the same time, the standardized design allows for interchangeability between modules, and if one adsorption module 2 fails, a spare module can be quickly replaced, reducing system downtime.
[0031] Specifically, each adsorption module 2 is connected to the desorption module 1 via a corrosion-resistant pipe (such as stainless steel) to facilitate the transfer of waste gas from the adsorption module 2 to the desorption module 1 and the reverse transfer of the regeneration medium. Simultaneously, each adsorption module 2 is connected to the desorption module 1 via an industrial-grade network cable or fiber optic cable. Both the main control cabinet 3 and the auxiliary control cabinet 4 utilize PLCs and communicate via the industrial Ethernet protocol to issue control commands and provide operational status feedback. The connection between the adsorption module 2 and the desorption module 1 via only one pipe and one network cable (or fiber optic cable) significantly simplifies the system structure compared to the multi-pipeline, multi-line design of traditional systems. This not only reduces the difficulty of wiring during installation but also reduces leakage risks and troubleshooting steps, significantly lowering daily maintenance costs.
[0032] The system completely separates the material transmission (pipeline) of waste gas / regeneration medium from the control signal transmission (network cable / fiber optic cable), avoiding corrosion or interference to the signal lines during material transmission, reducing the risk of abnormal material transmission due to line failure, and improving the safety of system operation.
[0033] The system adopts a master-slave PLC collaborative control architecture. The master PLC of the desorption module 1 serves as the central control unit, which can centrally manage all adsorption modules 2. The slave PLCs of adsorption modules 2 are responsible for local control and provide real-time status feedback, achieving efficient communication via network cable or fiber optic cable. This hierarchical control mode reduces signal interference, ensures real-time transmission of control commands and status data, and improves the stability and reliability of system operation.
[0034] The adsorption module 2 adopts a standardized design, with uniform mounting holes on the bottom of its outer shell. It can be fixed to the ground or a bracket with bolts, or stacked vertically using a stacking bracket. The connection between the desorption module 1 and the adsorption module 2 has a standardized interface, and pipes and network cables are connected to the interface via quick connectors. A single person can complete the installation and removal of the module. In short, the outer shell size, mounting holes, and connection interfaces are uniform, and the installation process is completely standardized. Furthermore, the adsorption module 2 and the desorption module 1 achieve quick plug-and-play connection through the standardized interface, eliminating the need for complex on-site debugging, significantly shortening the construction cycle and improving system deployment efficiency.
[0035] Among them, the shell structure of the adsorption module 2 is standardized in size, and the mounting and fixing holes of each adsorption module 2 are completely consistent, which can realize stacked or parallel installation. When the number of expansions is large, they can also be stacked and arranged in parallel at the same time, realizing flexible arrangement according to the site space, which is especially suitable for scenarios with limited factory space and improves space utilization.
[0036] During operation, the main control cabinet 3 issues working instructions to each auxiliary control cabinet 4 based on the total waste gas treatment capacity. The auxiliary control cabinet 4 controls the operation of the adsorption unit in its module and feeds back real-time status data such as temperature, pressure, and adsorption saturation to the main control cabinet 3. When it is necessary to expand the treatment capacity, only the number of adsorption modules 2 needs to be increased. The main control cabinet 3 can automatically identify the new module and complete the parameter configuration to realize the expansion.
