Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring equipment technology, and in particular to an online monitoring system for organic waste gas emission concentration. Background Technology

[0002] In industrial production processes, such as petrochemicals, coating, printing, and pharmaceuticals, a large amount of waste gas containing volatile organic compounds (VOCs) is generated. These organic waste gases not only pollute the atmospheric environment, forming photochemical smog and ozone pollution, but also pose potential hazards to human health, such as irritating the respiratory tract and affecting the nervous system. Therefore, accurate and real-time monitoring of the concentration of organic waste gas emissions is crucial.

[0003] Traditional online monitoring systems for organic waste gas emission concentrations mostly use bolts to fasten filter elements. Replacing the filter elements requires specialized tools and a significant amount of time for disassembly and installation. This cumbersome operation demands highly skilled technicians. This complex replacement process not only prolongs equipment downtime and reduces production efficiency but also increases the company's labor costs. Therefore, we propose an online monitoring system for organic waste gas emission concentrations to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an online monitoring system for organic waste gas emission concentration to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An online monitoring system for organic waste gas emission concentration includes: a waste gas concentration monitoring head, a waste gas inlet pipe, and a waste gas outlet pipe. One end of the waste gas inlet pipe is connected to a connecting pipe. A filter pipe is connected between the connecting pipe and the waste gas outlet pipe. A mounting ring is fixedly installed at the top of the filter pipe. A mounting seat is movably inserted into the mounting ring. A double filter element is fixedly installed at the bottom of the mounting seat. A pull ring is fixedly installed at the top of the mounting seat. Two sets of sliding frames are slidably installed inside the mounting ring. Reset points are fixedly installed on both sides of each sliding frame. A spring is provided, along with two sets of guide rods and locking blocks. The locking blocks are movably inserted into the outside of the mounting base. A movable plate is slidably installed inside the sliding frame. A reset spring is fixedly installed between the top of the movable plate and the corresponding inner top wall of the sliding frame. Pull rods and inserts are fixedly installed on both sides of the movable plate, respectively. A connecting seat is fixedly installed on the top of the pull rod, and a pull handle is fixedly installed on the top of the connecting seat. One end of the exhaust pipe is connected to an exhaust hood. A support plate is fixedly installed inside the exhaust hood, and an exhaust gas concentration monitoring head is provided on one side of the support plate.

[0007] Preferably, the insert block is slidably installed at the bottom of the corresponding slide frame and movably inserted into the inside of the mounting ring, the pull ring is slidably installed at the top of the corresponding slide frame and the top of the mounting ring, the dual filter element is connected to the connecting pipe, and a connecting flange is fixedly installed on the side of the connecting pipe adjacent to the exhaust gas inlet pipe, a sealing gasket is abutting between the two sets of connecting flanges, and multiple sets of fastening bolts are provided between the two sets of connecting flanges.

[0008] Preferably, the mounting ring has two sets of sliding grooves inside, the two sets of sliding frames are slidably installed in the corresponding sliding grooves, and one end of each of the two sets of return springs is fixedly installed on one side of the corresponding sliding groove.

[0009] Preferably, the mounting ring has four sets of guide grooves inside, and the four sets of guide rods are slidably installed in the corresponding guide grooves.

[0010] Preferably, the two sets of return springs are mounted on the outer side of the corresponding pull rod, and the outer side of the mounting base has two sets of slots, in which the two sets of locking blocks are movably inserted.

[0011] Preferably, the top of the mounting ring is provided with a mounting groove, and the mounting seat is movably inserted into the mounting groove.

[0012] In this utility model, an online monitoring system for organic waste gas emission concentration is provided. By setting a connecting flange, sealing gasket, and fastening bolts between the waste gas inlet pipe and the connecting pipe, the connection is ensured to be airtight. The organic waste gas then flows from the waste gas inlet pipe into the connecting pipe and then into the double filter element in the filter pipe for filtration of impurities. Finally, it flows through the waste gas emission pipe to the emission hood for discharge. Inside the emission hood, a waste gas concentration monitoring head set on one side of the support plate monitors the concentration of the emitted waste gas in real time, thereby realizing online monitoring of the organic waste gas emission concentration. This effectively prevents organic waste gas leakage, avoids the escape of toxic and harmful gases and pollution of the surrounding environment, and ensures that the waste gas can flow completely into the subsequent monitoring process, thus ensuring the accuracy and integrity of the monitoring data.

[0013] This utility model features a reasonable structural design. A pull handle drives the connecting seat and pull rod to slide within the sliding frame, which in turn causes the moving plate and insert block to rise. The second return spring retracts, releasing the lock on the sliding frame. Pulling the handle then causes the connecting seat, moving plate, and sliding frame to move relative to each other under the constraints of the guide rod, guide groove, and sliding groove. The first return spring retracts, causing the locking block to disengage from the slot, releasing the lock on the mounting seat. The dual filter element can then be removed and replaced via the pull ring. After replacement, the mounting seat is placed in the mounting groove of the mounting ring, the slot is aligned with the locking block, and the handle is released. Under the elastic force of the first and second return springs, the dual filter element can be quickly installed without external force. This structural design makes the filter element replacement process simple and easy to understand, requiring no complicated operations or additional tools, greatly improving the efficiency of filter element replacement, saving time and labor costs, reducing the difficulty of equipment maintenance, facilitating daily maintenance and upkeep, and extending the service life of the equipment.
