Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment, and in particular to an exhaust gas treatment device for phosphorus pentasulfide production. Background Technology

[0002] Phosphorus pentasulfide is an important inorganic chemical raw material widely used in pesticides, lubricant additives, flame retardants, and organic synthesis. Its industrial production typically involves the direct reaction of yellow phosphorus with sulfur at high temperatures. This reaction is violent and produces large quantities of complex, highly corrosive, and toxic process exhaust gases.

[0003] Currently, existing phosphorus pentasulfide production tail gas treatment devices directly pass the tail gas into the filter device to filter it. The impact force of the tail gas impacts the filter plate, which will damage the filter plate and affect its service life after long-term use. Moreover, the excessively fast flow rate of the tail gas will also lead to poor filtration effect of the filter plate. Utility Model Content

[0004] To overcome the drawbacks of directly introducing exhaust gas into the filtration device and having it come into contact with the filter plate for filtration, where the impact force of the exhaust gas impacts the filter plate, causing damage to the filter plate over a long period of time and affecting its service life, and where excessively fast exhaust gas flow can also lead to poor filtration efficiency, the technical problem to be solved is: to provide an exhaust gas treatment device for phosphorus pentasulfide production.

[0005] The technical solution of this utility model is: A device for treating tail gas from phosphorus pentasulfide production includes a gas pipeline with an inlet and an outlet at each end. A cooling pipe for cooling the tail gas is installed on the side of the gas pipeline near the inlet, and several detachable filter plates for filtering the tail gas are installed on the side of the gas pipeline near the outlet. A flow-blocking component is installed inside the gas pipeline between the cooling pipe and the filter plates. The flow-blocking component includes a housing that is rotatably connected to the gas pipeline. Flow-blocking plates for slowing down the tail gas flow are evenly distributed circumferentially inside the housing.

[0006] In one embodiment, the cooling pipe has an inlet for coolant to enter and an outlet for coolant to exit.

[0007] In one embodiment, a drive motor is provided on the side of the outer wall of the gas pipe near the flow obstruction, and a rotating shaft connected to the output shaft of the drive motor is rotatably connected to the outer wall of the gas pipe. A drive wheel is provided on the rotating shaft, and a toothed ring that cooperates with the drive wheel is provided on the outer wall of the outer casing.

[0008] In one embodiment, a spray assembly is provided on the outer wall of the gas pipe near the filter plate. The output end of the spray assembly is connected to the gas pipe. A collection tank is provided on the bottom of the gas pipe near the filter plate, and a drain port is provided on the collection tank.

[0009] In one embodiment, a soundproof frame is provided on the outer wall of the gas pipe, the soundproof frame is located between the drive wheel and the spray assembly, the rotating shaft extends to the soundproof frame, and a striking element is provided on the rotating shaft inside the soundproof frame, the striking element contacting and engaging with the outer wall of the gas pipe.

[0010] The beneficial effects are: 1. This utility model slows down the exhaust gas flow rate by rotating the baffle plate, preventing the exhaust gas from directly impacting the filter plate and shortening the service life of the filter plate. 2. The purification liquid is atomized by the spray component and introduced into the gas pipeline, so that the purification liquid reacts fully with the exhaust gas and effectively purifies the exhaust gas in the gas pipeline. 3. The rotating striking component strikes the gas pipe, causing the gas pipe to vibrate, which in turn causes the filter plate to vibrate, shaking off impurities attached to the filter plate, preventing the filter plate from clogging and extending the service life of the filter plate.

[0015] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] A device for treating tail gas from phosphorus pentasulfide production, such as Figure 1-3As shown, the system includes a gas pipeline 1, with an inlet and an outlet at each end. A cooling pipe 2 for cooling the exhaust gas inside the gas pipeline 1 is provided on the side of the gas pipeline 1 near the inlet. Several detachable filter plates 6 for filtering the exhaust gas are installed on the side of the gas pipeline 1 near the outlet. A flow-blocking component 4 is provided inside the gas pipeline 1, located between the cooling pipe 2 and the filter plates 6. The flow-blocking component 4 includes a housing, which is rotatably connected inside the gas pipeline 1. Flow-blocking plates for slowing down the exhaust gas flow are evenly distributed circumferentially inside the housing.

[0017] The cooling pipe 2 has an inlet for coolant to enter and an outlet for coolant to exit.

[0018] A drive motor 3 is provided on the outer wall of the gas pipe 1 near the flow obstruction 4. A rotating shaft 9 connected to the output shaft of the drive motor 3 is rotatably connected to the outer wall of the gas pipe 1. A drive wheel 5 is provided on the rotating shaft 9. A toothed ring that cooperates with the drive wheel 5 is provided on the outer wall of the outer casing.

[0019] A spray assembly 7 is provided on the outer wall of the gas pipe 1 near the filter plate 6. The output end of the spray assembly 7 is connected to the gas pipe 1. A collection tank is provided on the bottom of the gas pipe 1 near the filter plate 6, and a drain outlet is provided on the collection tank.

[0020] A soundproof frame 8 is provided on the outer wall of the gas pipe 1. The soundproof frame 8 is located between the drive wheel 5 and the spray assembly 7. The rotating shaft 9 extends to the soundproof frame 8. A striking element 10 is provided on the rotating shaft 9 inside the soundproof frame 8. The striking element 10 contacts and engages with the outer wall of the gas pipe 1.

[0021] Working principle: In use, the controller controls the start of the drive motor 3, which drives the rotating shaft 9 to rotate the drive wheel 5. The drive wheel 5, in conjunction with the toothed ring on the outer shell, drives the outer shell to rotate, which in turn drives the baffle plate to rotate. When the exhaust gas is introduced into the gas pipe 1 through the air inlet, the exhaust gas passes through the cooling pipe 2, the baffle 4, and the filter plate 6 in sequence for cooling, flow rate reduction, and filtration. Finally, it is discharged through the air outlet of the gas pipe 1. When the exhaust gas passes through the baffle 4, the baffle 4 slows down the exhaust gas flow rate by rotating the baffle plate, preventing the exhaust gas from directly impacting the filter plate 6 and shortening the service life of the filter plate 6. The liquid inlet of the spray assembly 7 is connected to the external pipeline for transporting purified liquid. The spray assembly 7 atomizes the purification liquid and introduces it into the gas pipe 1, allowing the purification liquid to fully react with the exhaust gas and effectively purify the exhaust gas in the gas pipe 1. The liquid is collected in the collection tank located below the filter plate 6 and discharged through the drain port. When the rotating shaft 9 rotates, it drives the striking member 10 to rotate and strike the gas pipe 1. The gas pipe 1 vibrates, which in turn drives the filter plate 6 to vibrate, shaking off impurities attached to the filter plate 6, preventing the filter plate 6 from clogging and extending the service life of the filter plate 6.
