Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical gas collection and treatment, specifically to an environmental protection gas treatment device for chemical workshop. BACKGROUND

[0002] In the chemical production process, a large amount of harmful gas containing ingredients will be released, such as hydrogen sulfide, ammonia, benzene and volatile organic compounds. These gases not only have significant harm to the environment and human health, but also may cause fire and explosion accidents. Therefore, efficient and reliable gas collection and treatment technology has become an important research direction of environmental protection and chemical safety.

[0003] At present, the gas treatment equipment is mostly modularized design, integrating gas collection, filtration, purification and other functions in a single device. For example, the patent with publication number CN219209360U proposes a chemical gas collection and treatment device, which optimizes the replacement process of the filter cartridge through the combination design of the detachable tank and the fixed tank, and solves the problem of complicated maintenance of traditional devices. The technical scheme cooperates the damper and the sliding block, so that the detachable tank can move along the guide rail and separate from the fixed tank, thereby improving the operation convenience.

[0004] However, the existing technology still has many deficiencies in practical application, which are specifically shown in the following aspects:

[0005] (1) The connection structure is unstable, and the damping system lacks coordination: in the above device, the fixed tank and the detachable tank are connected by threads, and the damping mechanism acts on the two parts respectively, causing the two parts to vibrate out of sync, which may lead to thread loosening, affecting the sealing and safety of gas treatment, and increasing the maintenance frequency and operation difficulty.

[0006] (2) The flexibility of the disassembly process is insufficient, and the operation is not convenient: in the existing technology, the detachable tank can only move in one direction along the guide rail. When the detachable tank needs to be removed, the device structure limits the operation space, causing the replacement process of the filter cartridge to be limited by the site conditions, increasing the operation complexity.

[0007] (3) The gas purification efficiency is limited, and the treatment diversity is insufficient: the current chemical gas treatment device mostly focuses on physical filtration or single chemical adsorption, which is difficult to efficiently purify chemical waste gas with complex composition and large concentration fluctuation. Especially when dealing with multiple toxic gases or trace organic matter, the adsorption and purification effect of the existing device is difficult to meet the standard.

[0008] (4) The automation level is low, and lacks intelligent monitoring and dynamic adjustment capability: traditional gas treatment devices mostly rely on manual operation and do not have real-time monitoring sensors and automatic adjustment functions, which makes it difficult to adjust the treatment mode according to the changes of gas concentration and flow, resulting in waste of resources or poor treatment effect.

[0009] (5) Energy saving and environmental protection is insufficient, the operation cost is higher: the existing equipment consumes more energy and filter material in the gas purification process, it is difficult to meet the requirements of energy saving and environmental protection, and increases the operation cost of enterprises.

[0010] Therefore, an environmental protection gas treatment device for chemical plant is needed to meet the technical needs of chemical gas collection and treatment. Practical new type content

[0011] The utility model discloses an environmental protection gas treatment device for chemical plant to solve the problems in the background art.

[0012] To achieve the above object, the utility model provides an environmental protection gas treatment device for chemical plant, through optimizing connecting structure, improving damping coordination, multistage purification design and intelligent control technology, the efficiency of gas collection and purification is improved significantly, and the operation convenience and safety of the device are enhanced. Specifically provide the following technical scheme:

[0018] Preferably, a buffer spring is installed in the buffer groove, one end of the buffer spring is installed on the telescopic rod, and the other end of the buffer spring is installed on the inner wall of the buffer groove.

[0019] Preferably, a sliding rod guide hole is formed on the fixed frame, and a sliding rod is slidingly installed in the sliding rod guide hole, and the other end of the sliding rod is installed on the movable frame.

[0020] Preferably, a limiting piece is installed on one side of the fixed frame, and the screw rod sleeve is rotatably installed on the limiting piece.

[0021] Preferably, a rotating groove is formed on the movable tank, and the movable frame is clamped in the rotating groove.

[0023] Preferably, buckles and clamping blocks are arranged on the fixed tank and the movable tank, and the buckles and the clamping blocks are matched with each other.

[0024] Compared with the prior art, the present application has the following advantages:

[0025] 1. Synchronous damping and greatly improved connection stability

[0026] The damping structure of the fixed tank and the movable tank is optimized, and through synchronous damping design, the vibration coordination of the two tanks during operation is realized, and the problem of thread loosening caused by asynchronous vibration is avoided.

[0027] The damping assembly adopts linkage damping design, and through the multi-directional buffer mechanism, the stability during operation is ensured, and the durability and sealing performance of the connecting part are improved. Even in a high-flow and high-pressure operating environment, the device can still maintain the integrity of the gas treatment path, prevent leakage, and ensure long-term stable operation of the equipment.

[0028] 2. Flexible and convenient disassembly mechanism

[0029] Through the linkage design of the screw rod and the sliding block, the movable tank can move freely in multiple directions, greatly improving the convenience and flexibility of the disassembly process.

[0030] The operator only needs to simply adjust the position of the screw rod to quickly separate or connect the movable tank, without the need for additional tools or complex operations. The disassembly process of the movable tank significantly reduces the demand for operating space, and is suitable for different workshop environments, especially in limited space scenarios.

[0031] 3. Integrated design of multi-stage purification system

[0032] The present application adopts a multi-stage purification technology, and in view of the characteristics of complex composition and variable concentration of waste gas in a chemical plant, a high-efficiency waste gas treatment process is designed.

[0033] The primary filter layer uses a combination of activated carbon and catalyst to quickly remove particulate pollutants and toxic components from harmful gases, enhancing the initial purification effect. The secondary treatment layer uses chemical spraying technology to achieve deep oxidation and adsorption of volatile organic compounds, effectively treating high-concentration toxic gases. The multi-stage purification layer-by-layer processing scheme is suitable for various complex components of waste gas, ensuring that the waste gas meets the standards before discharge.

[0034] 4. Intelligent dynamic adjustment and real-time monitoring

[0035] The device is equipped with various sensors and feedback systems, which can dynamically adjust the processing parameters according to the composition, concentration and flow changes of the waste gas, improving the intelligent level of the system.

[0036] Gas concentration sensors and flow sensors monitor the waste gas entering the system in real time, automatically adjusting the adsorption unit, spraying intensity and flow path through the control module to ensure that the processing efficiency is always at its best. The system can adjust the fan power and the operating frequency of the purification module through the feedback mechanism, saving energy and avoiding over-processing problems, and improving resource utilization efficiency.

[0037] 5. Environmental protection, energy saving and resource recycling

[0038] The invention significantly reduces operating costs and enhances environmental friendliness through optimized energy consumption design and waste gas recovery technology.

[0039] In the purification module, the amount of spraying agent and adsorption material is accurately calculated to reduce the waste of chemical reagents, and the purification agent is recycled multiple times to further reduce resource consumption. The gas recovery device in the system can perform secondary treatment on the incompletely purified waste gas to achieve harmless emission, avoid secondary pollution, and reduce processing costs.

[0040] 6. Improved operation safety and maintenance convenience

[0041] The device focuses on operation safety in design, reducing the possibility of human error through integrated linkage design and intelligent control functions.

[0042] The disassembly process uses electric drive components instead of manual operation to avoid safety risks in high-pressure and high-flow gas environments, while significantly improving operation efficiency. The automatic cleaning system is introduced during equipment maintenance to clean the residues of key components through automatic spraying and airflow backwashing, extending the service life of the equipment, reducing maintenance frequency and labor costs.

[0043] 7. Strong adaptability of modular structure

[0044] The invention uses modular design, and users can flexibly adjust the processing capacity and component configuration of the device according to the characteristics of the waste gas emission in the workshop.

[0045] Modular purification unit can be added or replaced according to the composition of waste gas, specific filter or adsorption components, ensure that the device adapts to different types of chemical plant waste gas treatment needs. When the production needs change or new pollutant composition appears, the user can quickly adjust the device configuration, without the need for overall replacement of the device, saving the cost of equipment investment.

[0046] 8、Full-process intelligent feedback control, realize efficient automatic operation

[0047] The present application realizes the full-process automation management from gas collection to treatment and discharge through intelligent feedback control algorithm.

[0048] The system adjusts the running state of each level purification module according to the real-time monitoring data of waste gas concentration and flow, ensures the stable treatment effect, and maximally reduces the energy consumption. The discharge module controls the exhaust speed and flow through the intelligent exhaust valve, ensures that the gas discharge meets the environmental protection standard, and further optimizes the operation efficiency.
