Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a chlorination furnace inlet air filtration device. Background Technology

[0002] A chlorination furnace is a metallurgical furnace used for the chlorination process. Its main function is to mix solid materials with reducing agents to form lumps, which then react with chlorine gas in a vertical furnace to produce anhydrous chlorides. Chlorination furnaces have wide applications in industrial production, especially in the production of titanium tetrachloride. Commonly used processes include fluidized bed chlorination and molten salt chlorination. There are various types of chlorination furnaces, including fluidized bed chlorination furnaces and molten salt chlorination furnaces. Fluidized bed chlorination furnaces utilize the mass and heat transfer conditions between gas and solid, and have advantages such as short process flow, large production capacity, and low environmental pollution. In order to ensure the purity of chlorides processed in the chlorination furnace, it is necessary to reduce impurities in the air entering the furnace. Traditional filtration devices mostly use a single set of filter screens, which have poor filtration effects. To improve this situation, a chlorination furnace inlet air filtration device is proposed.

[0003] As disclosed in the authorization announcement number CN219199244U, a heating furnace air intake filtration device includes a heating furnace body and a filtration mechanism. A horizontal plate is fixedly connected to the outer surface of the heating furnace body. The filtration mechanism includes a rectangular chamber. The rectangular chamber is fixedly connected to the upper surface of the horizontal plate. An air intake pipe and a filter plate are connected inside the rectangular chamber. A rectangular hole is opened at the top of the rectangular chamber. A filter plate and a limiting plate are slidably connected inside the rectangular hole. Limiting plates are fixedly connected to the inner walls of the front and rear sides of the rectangular chamber. One end face of the limiting plate is slidably connected to the outer side face of the filter plate. A rectangular groove is opened at the inner bottom of the rectangular chamber. One end of the filter plate is slidably connected to the inside of the rectangular groove.

[0004] Although it solves the problem of existing technologies that absorb outside air and draw some impurities into the heating furnace, especially plastic bags and other items, the burning of plastic bags will produce harmful gases that pollute the atmosphere;

[0005] However, this does not solve the problem that existing filtration devices are not conducive to convenient multi-mode and multi-stage gas filtration during use, nor to quick disassembly and replacement of the filter screen, thus affecting the gas filtration effect and the convenience of filter screen disassembly and replacement. Utility Model Content

[0006] The purpose of this utility model is to provide a chlorination furnace inlet gas filtration device to solve the problems mentioned in the background art, such as the inconvenience of multi-mode and multi-stage gas filtration, the difficulty in quickly disassembling and replacing the filter screen, which affects the gas filtration effect and the convenience of filter screen disassembly and replacement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a chlorination furnace inlet air filtration device, comprising a lower tank and an upper tank, wherein the upper tank is installed at the top of the lower tank, a placement plate is installed inside the lower tank, and multiple sets of filter bags at equal intervals are installed at the bottom of the placement plate. Each filter bag has a funnel-shaped tube installed at its top, and the funnel-shaped tube is connected to the filter bag. Multiple sets of dispersion tubes at equal intervals are installed on the inner wall of the upper tank, and the bottom of the dispersion tubes is provided with equally spaced air outlets, and the air outlets correspond one-to-one with the funnel-shaped tubes. A liquid tank is provided outside the lower tank, and an air outlet pipe is installed on the outer wall of the lower tank, and the air outlet pipe is connected to the lower tank.

[0008] Preferably, a fan is installed at the top of the liquid tank, and the fan is fixedly connected to the liquid tank.

[0009] Preferably, a connecting pipe is installed at the top of the liquid tank on one side of the fan, and a distributor is provided at the end of the connecting pipe away from the liquid tank, and the distributor is connected to the dispersing pipe.

[0010] Preferably, the bottom of the fan is provided with an air inlet pipe, and the liquid tank is provided with a neutralizing liquid, which covers the lower port of the air inlet pipe.

[0011] Preferably, a suction pipe is provided on the side wall of the fan, and an external thread is installed on the outer wall of the suction pipe.

[0012] Preferably, the inner wall of the suction tube is provided with four sets of equally spaced limiting grooves, and a filter screen is provided inside the suction tube.

[0013] Preferably, four sets of equally spaced limiting blocks are installed on the outer wall of the filter screen, and the limiting blocks are slidably connected to the limiting groove.

[0014] Preferably, a limiting ring is provided on the outside of the suction tube, and an internal thread is provided on the inner wall of the limiting ring, and the internal thread is threadedly connected to the external thread.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the filtration device not only realizes convenient multi-mode and multi-stage gas filtration and facilitates quick disassembly and replacement of the filter screen, but also improves the gas filtration effect and the convenience of disassembly and replacement of the filter screen.

[0016] (1) The gas outlet pipe is connected to the chlorination furnace through a pipe. The fan draws the external gas into the gas inlet pipe through the suction pipe. The external gas first passes through the filter screen, which filters out large particles of impurities in the gas. The gas flows through the gas inlet pipe into the neutralizing liquid, which neutralizes and absorbs the acidic and alkaline gases in the gas. The treated gas flows through the connecting pipe into the distributor and is then divided into multiple sets of dispersion tubes. The gas flows through the outlet at the bottom of the dispersion tube into the funnel-shaped tube and then into the filter bag. The filter bag filters the gas again to remove the fine particles. The gas that has undergone multiple treatments flows through the gas outlet pipe into the chlorination furnace to participate in the chlorination process. This achieves convenient multi-stage and multi-mode gas filtration, which facilitates multi-stage gas filtration and improves the gas filtration effect.

[0017] (2) When the filter screen accumulates dust on its surface after long-term use, it will affect the filtration effect. At this time, the limiting ring can be rotated to remove the limiting ring from the surface of the suction tube. Then, the filter screen can be taken out from the inside of the suction tube. Take out a new filter screen, align the limiting block with the limiting groove, press the filter screen, and let the filter screen drive the limiting block to slide inside the limiting groove. The filter screen can then be installed inside the suction tube. The limiting block and the limiting groove provide limiting sliding support for the filter screen. After that, tighten the limiting ring again. This makes it convenient to quickly disassemble and replace the filter screen and improves the convenience of disassembling and replacing the filter screen. Attached Figure Description

The upper tank 20 is installed at the top of the lower tank 1. A placement plate 8 is installed inside the lower tank 1. Multiple sets of filter bags 9 with equal spacing are installed at the bottom of the placement plate 8. The top of each filter bag 9 is equipped with a funnel-shaped tube 10, and the funnel-shaped tube 10 is connected to the filter bag 9. Multiple sets of dispersion tubes 11 with equal spacing are installed on the inner wall of the upper tank 20. The bottom of the dispersion tube 11 is provided with equally spaced air outlets, and the air outlets correspond one-to-one with the funnel-shaped tubes 10. A liquid tank 2 is provided outside the lower tank 1. An air outlet pipe 7 is installed on the outer wall of the lower tank 1, and the air outlet pipe 7 is connected to the lower tank 1.

[0026] The outlet pipe 7 is connected to the chlorination furnace through a pipe. The blower 3 is turned on, and the blower 3 draws the external gas into the inlet pipe 6 through the suction pipe 12. The external gas first passes through the filter screen 14, which filters out large particles in the gas. The gas then flows through the inlet pipe 6 into the neutralizing liquid 19, where the neutralizing liquid 19 neutralizes and absorbs the acidic and alkaline gases in the gas. The treated gas flows through the connecting pipe 4 into the distributor 5, and then through the distributor 5 into multiple sets of dispersion pipes 11. The gas flows through the outlet at the bottom of the dispersion pipe 11 into the funnel-shaped pipe 10 and then into the filter bag 9, where the filter bag 9 filters the gas again to remove the fine particles. The gas that has undergone multiple treatments flows through the outlet pipe 7 into the chlorination furnace to participate in the chlorination process. This achieves convenient multi-mode gas filtration, facilitates multi-stage gas filtration, and improves the gas filtration effect.

[0027] A blower 3 is installed at the top of the liquid tank 2, and the blower 3 is fixedly connected to the liquid tank 2. A connecting pipe 4 is installed at the top of the liquid tank 2 on one side of the blower 3. A distributor 5 is provided at the end of the connecting pipe 4 away from the liquid tank 2, and the distributor 5 is connected to the dispersing pipe 11.

[0028] The bottom of the blower 3 is provided with an air inlet pipe 6, the liquid tank 2 is provided with a neutralizing liquid 19, and the neutralizing liquid 19 does not pass through the lower port of the air inlet pipe 6. The side wall of the blower 3 is provided with a suction pipe 12, and the outer wall of the suction pipe 12 is provided with an external thread 18.

[0029] The inner wall of the suction tube 12 is provided with four sets of equally spaced limiting grooves 17, the inside of the suction tube 12 is provided with a filter screen 14, and the outer wall of the filter screen 14 is provided with four sets of equally spaced limiting blocks 16, and the limiting blocks 16 are slidably connected to the limiting grooves 17.

[0031] After prolonged use, dust will accumulate on the surface of the filter screen 14, affecting the filtration effect. At this time, the limiting ring 13 can be rotated to remove it from the surface of the suction tube 12 through the thread engagement of the internal thread 15 and the external thread 18. Then, the filter screen 14 can be removed from the inside of the suction tube 12. Take out a new filter screen 14, align the limiting block 16 with the limiting groove 17, and press the filter screen 14. The filter screen 14 will drive the limiting block 16 to slide inside the limiting groove 17, thus installing the filter screen 14 into the inside of the suction tube 12. The limiting block 16 and the limiting groove 17 provide limiting sliding support for the filter screen 14. After that, tighten the limiting ring 13 again. This facilitates quick disassembly and replacement of the filter screen and improves the convenience of filter screen disassembly and replacement.

[0032] Working principle: The outlet pipe 7 is connected to the chlorination furnace via a pipeline. External gas is drawn into the inlet pipe 6 by the blower 3 through the suction pipe 12. The external gas first passes through the filter screen 14, which filters out large particles. The gas then flows through the inlet pipe 6 to the neutralization liquid 19, where it neutralizes and absorbs acidic and alkaline gases. The treated gas flows through the connecting pipe 4 to the distributor 5, and is then divided into multiple sets of dispersion pipes 11. The gas flows through the outlets at the bottom of the dispersion pipes 11 into the funnel-shaped pipes 10, and then into the filter bags 9. The filter bags 9 further filter the gas, removing fine particles. This process involves multiple treatments. The gas flows through the outlet pipe 7 into the chlorination furnace to participate in the chlorination process. After prolonged use, dust accumulates on the surface of the filter screen 14, which affects the filtration effect. At this time, the limiting ring 13 can be rotated to remove it from the surface of the suction pipe 12 through the thread engagement of the internal thread 15 and the external thread 18. Then, the filter screen 14 can be removed from the inside of the suction pipe 12. Take a new filter screen 14, align the limiting block 16 with the limiting groove 17, and press the filter screen 14. The filter screen 14 will drive the limiting block 16 to slide inside the limiting groove 17, thus installing the filter screen 14 into the inside of the suction pipe 12. The limiting block 16 and the limiting groove 17 provide limiting sliding support for the filter screen 14. After that, tighten the limiting ring 13 again. The above is the complete usage of the chlorination furnace inlet filter device.
