Description

Technical Field

[0001] This utility model relates to the technical field of waste gas collection devices, specifically a novel high-efficiency chlorination furnace waste gas collection device. Background Technology

[0002] A chlorination furnace is a metallurgical furnace used for the chlorination process. It is mainly used to mix solid materials to be chlorinated with reducing agents to form lumps, which are then reacted with chlorine gas in a vertical furnace to produce anhydrous chlorides. Chlorination furnaces are widely used in the production of titanium tetrachloride, with specific processes including fluidized bed chlorination and molten salt chlorination. After the chlorination furnace has processed the raw materials, it will generate waste gas. If this waste gas is directly discharged into the atmosphere, it will cause environmental pollution. Therefore, the waste gas needs to be collected and treated before being discharged. In order to better collect and treat the waste gas, a new type of high-efficiency chlorination furnace waste gas collection device is proposed.

[0003] For example, the high-temperature furnace exhaust gas collection device disclosed in the authorization announcement number CN220103770U includes a high-temperature furnace body, a connecting rod fixedly connected to the outer wall of the high-temperature furnace body, a purification box fixedly connected to one end of the connecting rod, an installation flange provided on the outer wall of the high-temperature furnace body and below the connecting rod, a U-shaped pipe fixedly connected to the outer wall of the installation flange, one end of the U-shaped pipe extending into the interior of the purification box, and a fan provided on the inner wall of the U-shaped pipe;

[0004] Although it allows the purification box to be fixed to the high-temperature furnace body via a connecting rod, and the exhaust gas generated by the high-temperature furnace body to be drawn into the purification box along the U-shaped pipe when the exhaust gas passes through the U-shaped pipe, the exhaust gas is filtered by the filter screen, which can block large particles of impurities in the exhaust gas and cause the large particles of impurities to fall to the bottom of the U-shaped pipe. Water is filled into the purification box, and a one-way valve is set to prevent water from entering the U-shaped pipe. The exhaust gas can pass through the one-way valve to enter the water for filtration, so that the exhaust gas is thoroughly purified.

[0005] However, the existing waste gas collection devices do not solve the problems of being unable to conveniently extract and absorb chlorination furnace waste gas for multi-stage filtration and to adjust the extraction range in a coordinated manner, nor are they conducive to the quick disassembly and replacement of filter blocks, which affects the waste gas treatment effect and the flexibility of use. Utility Model Content

[0006] The purpose of this invention is to provide a new type of high-efficiency chlorination furnace exhaust gas collection device to solve the problems mentioned in the background art, such as the inconvenience of exhaust gas collection devices for multi-stage filtration and linkage adjustment of the suction range, the difficulty in quickly disassembling and replacing filter blocks, and the impact on the exhaust gas treatment effect and the flexibility of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel high-efficiency chlorination furnace waste gas collection device, comprising a gas collecting hood and a hoisting frame, characterized in that: four sets of hoisting frames with equal spacing are provided at the top of the gas collecting hood, and the gas collecting hood is connected to the outside through the hoisting frames; a connecting pipe is installed at the center of the top of the gas collecting hood; a treatment box is provided outside the gas collecting hood, and the connecting pipe extends into the interior of the treatment box; a fan is installed inside the gas collecting hood, and the output end of the fan is connected to the connecting pipe; an exhaust pipe is provided at the top of the treatment box, and the exhaust pipe is fixedly connected to the treatment box; a filter block is provided above the exhaust pipe, and the filter block is slidably connected to the exhaust pipe.

[0008] Preferably, the bottom of the gas collecting hood is symmetrically provided with two adjustment plates, each adjustment plate is provided with a hinge shaft on the side of the adjustment plate near the gas collecting hood, and the adjustment plate is movably connected to the gas collecting hood through the hinge shaft, and a flexible connecting plate is provided between adjacent adjustment plates.

[0009] Preferably, an electric push rod is provided on the side wall of the gas collection hood on one side of the adjustment plate, and the electric push rod is movably connected to the gas collection hood.

[0010] Preferably, each of the electric push rods has a push arm installed at its output end, and each push arm has a linkage shaft at the end near the adjustment plate, and the push arm is movably connected to the adjustment plate through the linkage shaft.

[0011] Preferably, the bottom end of the filter block is provided with a plug-in block, and the plug-in block is fixedly connected to the filter block.

[0012] Preferably, limit rings are symmetrically arranged on the side wall of the plug block, and each limit ring is provided with a limit post inside, and the limit post is slidably connected to the limit ring.

[0013] Preferably, each of the limiting posts is provided with a spring, and the two ends of the spring are respectively connected to the limiting post and the limiting ring.

[0014] Preferably, a plug buckle is slidably provided at the center of the plug block, and the limiting post engages with the groove on the surface of the plug buckle, and the plug buckle is connected to the air outlet pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the waste gas collection device not only realizes the convenient extraction and absorption of chlorination furnace waste gas for multi-stage filtration and linkage adjustment of the extraction range, but also facilitates the quick disassembly and replacement of the filter block, and improves the waste gas treatment effect and the flexibility of use.

[0016] (1) The gas collection hood is hoisted above the chlorination furnace by the hoisting frame. The exhaust gas is drawn into the connecting pipe by the fan and transported to the inside of the treatment box through the connecting pipe. The treatment box is filled with neutralizing liquid, and the liquid level is higher than the discharge port of the connecting pipe. After the exhaust gas is discharged into the neutralizing liquid, the neutralizing liquid neutralizes and absorbs the impurities and toxic gases in the exhaust gas. The remaining exhaust gas is discharged through the exhaust pipe and the filter block. The filter block can perform secondary filtration of the exhaust gas to ensure that the discharged gas meets the emission standards. When the filter block needs to be replaced after long-term use, pull out the limiting column. The limiting column slides inside the limiting ring and the limiting column squeezes the spring to make the plug buckle disengage from the limiting column. Then pull the filter block upward, and the filter block drives the plug buckle to disengage from the plug block. Then replace the filter block and reinstall it. This realizes convenient extraction and absorption of chlorination furnace exhaust gas for multi-stage filtration treatment, which facilitates quick disassembly and replacement of the filter block, improves the effect of exhaust gas treatment and the convenience of replacing the filter block.

[0017] (2) When the suction range needs to be adjusted, the electric push rod drives the push arm to move, and the push arm drives the adjustment plate to rotate around the hinge axis through the linkage shaft, so that the four sets of adjustment plates can rotate outward synchronously. Since the flexible connecting plate is a flexible design, it does not affect the rotation of the adjustment plate. After the adjustment plate rotates, the opening area of ​​the adjustment plate and the flexible connecting plate expands, thereby increasing the suction area and thus increasing the suction range, so as to better absorb and collect the chlorination furnace exhaust gas. This realizes convenient linkage adjustment of the suction range and improves the flexibility of use. Attached Figure Description

[0025] Please see Figure 1-5 The present invention provides an embodiment of a novel high-efficiency chlorination furnace exhaust gas collection device, comprising a gas collection hood 2 and a hoisting frame 1, characterized in that: four sets of hoisting frames 1 with equal spacing are provided at the top of the gas collection hood 2, and the gas collection hood 2 is connected to the outside through the hoisting frames 1; a connecting pipe 5 is installed at the center of the top of the gas collection hood 2; a treatment box 6 is provided outside the gas collection hood 2, and the connecting pipe 5 extends into the interior of the treatment box 6; a fan 9 is installed inside the gas collection hood 2, and the output end of the fan 9 is connected to the connecting pipe 5; an exhaust pipe 7 is provided at the top of the treatment box 6, and the exhaust pipe 7 is fixedly connected to the treatment box 6; a filter block 8 is provided above the exhaust pipe 7, and the filter block 8 is slidably connected to the exhaust pipe 7.

[0026] The gas collection hood 2 is hoisted above the chlorination furnace using the hoisting frame 1. The blower 9 is turned on, drawing the exhaust gas into the connecting pipe 5 and then transporting it to the treatment tank 6. The treatment tank 6 contains neutralizing liquid, with the liquid level higher than the discharge port of the connecting pipe 5. After the exhaust gas enters the neutralizing liquid, the liquid neutralizes and absorbs impurities and toxic gases in the exhaust gas. The remaining exhaust gas is discharged through the outlet pipe 7 and filter block 8. The filter block 8 performs secondary filtration of the exhaust gas to ensure that the discharged gas meets emission standards. When the filter block 8 is used for a long time... When replacement is needed, pull out the limiting post 17. The limiting post 17 slides inside the limiting ring 18 and squeezes the spring 16 to disengage the plug buckle 14 from the limiting post 17. Then pull the filter block 8 upward. The filter block 8 drives the plug buckle 14 to disengage from the plug block 15. Then replace the filter block 8 and reinstall it. This realizes convenient multi-stage filtration of chlorination furnace exhaust gas, facilitates quick disassembly and replacement of filter blocks, improves the exhaust gas treatment effect and the convenience of filter block replacement.

[0027] The bottom of the gas collection hood 2 is symmetrically provided with two adjustment plates 3. Each adjustment plate 3 is provided with a hinge shaft 12 on the side of the gas collection hood 2. The adjustment plates 3 are movably connected to the gas collection hood 2 through the hinge shaft 12. A flexible connecting plate 4 is provided between adjacent adjustment plates 3.

[0028] Electric push rods 11 are installed on the side wall of the gas collection hood 2 on one side of the adjustment plate 3. The electric push rods 11 serve as power drives and are movably connected to the gas collection hood 2. Push arms 13 are installed at the output end of the electric push rods 11. A linkage shaft 10 is installed at the end of the push arm 13 near the adjustment plate 3, and the push arm 13 is movably connected to the adjustment plate 3 through the linkage shaft 10.

[0029] The bottom end of the filter block 8 is provided with a plug-in block 15, and the plug-in block 15 is fixedly connected to the filter block 8. Limiting rings 18 are symmetrically provided on the side wall of the plug-in block 15. Limiting posts 17 are provided inside the limiting rings 18, and the limiting posts 17 are slidably connected to the limiting rings 18.

[0030] Springs 16 are provided on the surface of the limiting post 17, and the two ends of the springs 16 are connected to the limiting post 17 and the limiting ring 18 respectively. A plug buckle 14 is slidably provided at the center of the plug block 15, and the limiting post 17 and the groove on the surface of the plug buckle 14 are engaged, and the plug buckle 14 is connected to the air outlet pipe 7.

[0031] When the suction range needs to be adjusted, the electric push rod 11 is opened, which drives the push arm 13 to move. The push arm 13 drives the adjustment plate 3 to rotate around the hinge shaft 12 via the linkage shaft 10, so that the four sets of adjustment plates 3 can rotate outward synchronously. Because the flexible connecting plate 4 is a flexible design, it does not affect the rotation of the adjustment plate 3. After the adjustment plate 3 rotates, the opening area of ​​the adjustment plate 3 and the flexible connecting plate 4 increases, thereby increasing the suction area and thus increasing the suction range, so as to better absorb and collect the chlorination furnace exhaust gas. This realizes convenient linkage adjustment of the suction range and improves the flexibility of use.

[0032] Working principle: The gas collection hood 2 is hoisted above the chlorination furnace by the hoisting frame 1. The blower 9 is turned on, and the blower 9 draws the waste gas into the connecting pipe 5 and then transports it to the inside of the treatment box 6. The treatment box 6 contains neutralizing liquid, and the liquid level is higher than the discharge port of the connecting pipe 5. After the waste gas is discharged into the neutralizing liquid, the neutralizing liquid neutralizes and absorbs the impurities and toxic gases in the waste gas. The remaining waste gas is discharged through the exhaust pipe 7 and the filter block 8. The filter block 8 can perform secondary filtration of the waste gas to ensure that the discharged gas meets the emission standards. When the filter block 8 needs to be replaced after long-term use, the limiting post 17 is pulled outward. The limiting post 17 slides inside the limiting ring 18 and squeezes the spring 16, so that the plug buckle 14 engages with the limiting post 16. After column 17 is disengaged, filter block 8 is pulled upwards, causing filter block 8 to drive plug buckle 14 to disengage from plug block 15. Then, a new filter block 8 can be replaced and reinstalled. When the suction range needs to be adjusted, electric push rod 11 drives push arm 13 to move. Push arm 13 drives adjustment plate 3 to rotate around hinge shaft 12 via linkage shaft 10, so that the four sets of adjustment plates 3 can rotate outwards synchronously. Because flexible connecting plate 4 is flexible, it does not affect the rotation of adjustment plate 3. After adjustment plate 3 rotates, the opening area of ​​adjustment plate 3 and flexible connecting plate 4 increases, thereby increasing the suction area and thus increasing the suction range, so as to better absorb and collect chlorination furnace exhaust gas. The above is the complete usage of the new high-efficiency chlorination furnace exhaust gas collection device.
