Description

Technical Field

[0001] This utility model belongs to the field of purification tower technology, and in particular relates to a desulfurization and denitrification purification tower. Background Technology

[0002] Desulfurization and denitrification purification towers are important equipment for treating sulfur oxides and nitrogen oxides in industrial waste gas. Glass kilns generate a large amount of sulfur oxides during production, mainly sulfur dioxide. The emission of sulfur oxides not only pollutes the environment but also corrodes equipment and buildings. At the same time, glass kilns produce nitrogen oxides, mainly nitric oxide and nitrogen dioxide, during high-temperature combustion. The emission of nitrogen oxides leads to environmental problems such as acid rain and photochemical smog, and is also harmful to human health.

[0003] When desulfurizing and denitrifying exhaust gas, a purification tower is usually used. Liquids such as ammonia or urea, which can desulfurize and denitrify, are often sprayed through a spray device. When the exhaust gas passes through, it reacts with the liquid to remove sulfur oxides and nitrogen oxides. However, in the existing purification towers, the contact time between the exhaust gas and the liquid sprayed by the spray device is relatively short, resulting in a short desulfurization and denitrification time for the exhaust gas and affecting the treatment effect. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a desulfurization and denitrification purification tower.

[0005] To achieve the above objectives, this utility model proposes a desulfurization and denitrification purification tower, comprising a tower body, a gas transmission pipe connected to one side of the tower body, an exhaust pipe connected to the top of the tower body, a fixing ring fixedly connected to the inner wall of the tower body, a fixing cylinder fixedly connected to the inner arc surface of the fixing ring, a spiral tube fixedly connected to the inner arc surface of the fixing cylinder, a liquid inlet pipe fixedly connected to the side wall of the tower body, the liquid inlet pipe communicating with the spiral tube, and multiple nozzles arranged in a spiral pattern on the inner side of the spiral tube.

[0006] In one example, two support blocks are fixedly connected to the upper surface of the fixed ring, and a tapered plate is fixedly connected to the upper surface of the two support blocks.

[0007] In one example, a fixing post is fixedly connected to the inner side of the conical plate, the fixing post is located inside the spiral tube, and multiple conical blocks are fixedly connected to the outer side of the fixing post.

[0008] In one example, an inclined plate is fixedly connected to the inner wall of the tower body, the inclined plate is fixedly connected to a conical block, a drain pipe is connected to the outer side of the tower body, and a ventilation pipe is fixedly connected to the inclined plate, the ventilation pipe passing through the inclined plate.

[0009] In one example, a partition is fixedly connected between the inclined plate and the bottom of the tower body, a shell is fixedly connected between the partition and the side wall of the tower body, the shell is connected to a ventilation pipe, a filter plate is slidably connected inside the shell, a collection frame is placed on the bottom surface inside the tower body, and through holes are provided on the side wall of the tower body.

[0010] In one example, a filter screen is provided on the filter plate, a spring is fixedly connected between the filter plate and the side wall of the housing, a crossbar is fixedly connected to the other side of the filter plate, the crossbar passes through the partition, and an actuating component is provided on the other side of the partition.

[0011] In one example, the actuating assembly includes an actuating component fixedly connected to a partition, a motor fixedly connected to one side of the actuating component, a rotating disk fixedly connected to the main shaft of the motor, an actuating block fixedly connected to the side of the rotating disk, and a protrusion fixedly connected to the lower surface of the crossbar.

[0012] The desulfurization and denitrification purification tower proposed in this utility model can bring the following beneficial effects:

[0013] Firstly, by setting up a fixed cylinder, the exhaust gas can only pass through the fixed cylinder and be discharged from the exhaust pipe. At the same time, ammonia or urea is sprayed into the fixed cylinder through the nozzles on the spiral tube, reducing the space and facilitating the contact between the exhaust gas and ammonia or urea when passing through the fixed cylinder, thereby improving the desulfurization and denitrification effect of the exhaust gas.

[0014] Secondly, by setting up a filter plate, when the exhaust gas passes through the filter plate, the filter plate filters the dust in the exhaust gas. Then the exhaust gas enters the ventilation pipe, passes through the inclined plate, and filters the dust before reaching the fixed cylinder, preventing dust from clogging the nozzle. The motor drives the rotating disk to rotate, and the actuating block moves the protrusion, causing the crossbar to pull the filter plate to slide. The spring stores force, and when the actuating block disengages from the protrusion, the spring pulls the filter plate back to its original position, forming vibration, which promotes the dust to fall off the filter plate and prevents the filter plate from clogging.

[0022] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes a desulfurization and denitrification purification tower, including a tower body 1, a gas transmission pipe 2 connected to one side of the tower body 1, an exhaust pipe connected to the top of the tower body 1, a fixing ring 3 fixedly connected to the inner wall of the tower body 1, a fixing cylinder 4 fixedly connected to the inner arc surface of the fixing ring 3, a spiral tube 5 fixedly connected to the inner arc surface of the fixing cylinder 4, a liquid inlet pipe 6 fixedly connected to the side wall of the tower body 1, the liquid inlet pipe 6 communicating with the spiral tube 5, and multiple nozzles 7 arranged in a spiral pattern on the inner side of the spiral tube 5 to discharge the exhaust gas from the glass kiln through the gas transmission pipe 2. After the exhaust gas enters the tower body 1 through the pipe connection, it passes through the fixed cylinder 4. At this time, ammonia or urea is transported into the spiral pipe 5 through the liquid inlet pipe 6. The ammonia or urea is sprayed out through the nozzle 7 on the spiral pipe 5 and reacts with the NOx in the flue gas of the glass kiln to generate nitrogen and water, thus performing desulfurization and denitrification treatment on the exhaust gas. By setting the fixed cylinder 4, the exhaust gas can only pass through the fixed cylinder 4 and be discharged from the exhaust pipe. At the same time, ammonia or urea is sprayed inside the fixed cylinder 4, reducing the space. When passing through the fixed cylinder 4, it is convenient for the exhaust gas to come into contact with ammonia or urea, thereby improving the desulfurization and denitrification effect of the exhaust gas.

[0024] like Figure 2As shown, two support blocks 8 are fixedly connected to the upper surface of the fixed ring 3, and a conical plate 9 is fixedly connected to the upper surface of the two support blocks 8. A fixed column 10 is fixedly connected to the inner side of the conical plate 9. The fixed column 10 is located inside the spiral tube 5. Multiple conical blocks 11 are fixedly connected to the outer side of the fixed column 10. An inclined plate 12 is fixedly connected to the inner wall of the tower body 1. The inclined plate 12 is fixedly connected to the conical blocks 11. The outer side of the tower body 1 is connected to the drain pipe 13. A ventilation pipe 14 is fixedly connected to the inclined plate 12. The ventilation pipe 14 passes through the inclined plate 12, and the exhaust gas undergoes desulfurization and desulfurization. After nitrification, the gas rises to the conical plate 9. The conical plate 9, the fixed column 10, and the conical block 11 are all made of heat-conducting materials. Water vapor is generated during the desulfurization and denitrification process. When it encounters the conical plate 9, the fixed column 10, and the conical block 11, the heat dissipation temperature decreases, and condensation occurs. The water droplets fall onto the inclined plate 12 and are discharged through the drain pipe 13 to collect the water and save water resources. The exhaust gas passes through the inclined plate 12 through the ventilation pipe 14. The ventilation pipe 14 is located at the higher end of the inclined plate 12, and the drain pipe 13 is located at the lower end of the inclined plate 12.

[0025] like Figure 2 As shown, a partition 15 is fixedly connected between the inclined plate 12 and the bottom of the tower body 1. A housing 16 is fixedly connected between the partition 15 and the side wall of the tower body 1. The housing 16 is connected to the ventilation pipe 14. A filter plate 17 is slidably connected inside the housing 16. A collection frame 18 is placed on the bottom surface inside the tower body 1. A through hole is provided on the side wall of the tower body 1. After the exhaust gas enters the tower body 1, it is first filtered. When the exhaust gas passes through the filter plate 17, the filter plate 17 filters the dust in the exhaust gas. Then the exhaust gas enters the ventilation pipe 14, passes through the inclined plate 12, and filters the dust before reaching the fixed cylinder 4 to prevent dust from clogging the nozzle 7. The dust on the filter plate 17 falls down under the action of gravity and falls into the collection frame 18. When cleaning the collection frame 18, the collection frame 18 can be pulled out from the through hole. The collection frame 18 is in close contact with the side wall of the through hole to prevent air leakage.

[0026] like Figure 4 As shown, a filter screen is provided on the filter plate 17. A spring 19 is fixedly connected between the filter plate 17 and the side wall of the housing 16. A crossbar 20 is fixedly connected to the other side of the filter plate 17. The crossbar 20 passes through the partition 15. An actuating assembly 21 is provided on the other side of the partition 15. The actuating assembly 21 includes a mounting plate 211, which is fixedly connected to the partition 15. A motor 212 is fixedly connected to one side of the mounting plate 211. The main shaft of the motor 212 is fixedly connected to a rotating disk 213. An actuating block 214 is fixedly connected to the side of the rotating disk 213. A protrusion 215 is fixedly connected to the lower surface of the crossbar 20. When filtering dust, the motor 212 drives the rotating disk 213 to rotate. The actuating block 214 actuates the protrusion 215, causing the crossbar 20 to pull the filter plate 17 to slide. The spring 19 stores force. When the actuating block 214 disengages from the protrusion 215, the spring 19 pulls the filter plate 17 back to its original position, forming vibration, which promotes the dust to fall off the filter plate 17 and avoids clogging the filter plate 17.

[0027] Working principle: The gas supply pipe 2 is connected to the exhaust pipe of the glass furnace. After the exhaust gas enters the tower body 1, it passes through the filter plate 17, which filters the dust in the exhaust gas. The motor 212 drives the rotating disk 213 to rotate, and the actuating block 214 actuates the protrusion 215, causing the crossbar 20 to pull the filter plate 17 to slide. The spring 19 stores force. When the actuating block 214 disengages from the protrusion 215, the spring 19 pulls the filter plate 17 back to its original position, creating vibration. The dust falls under the action of gravity and falls into the collection frame 18. The exhaust gas passes through the ventilation pipe 14, the inclined plate 12, and the liquid inlet pipe. 6. Ammonia or urea is transported into the spiral tube 5 and sprayed inward through the nozzle 7 on the spiral tube 5. It reacts with NOx in the flue gas of the glass kiln that passes through it to generate nitrogen and water, thus performing desulfurization and denitrification treatment on the tail gas. After desulfurization and denitrification treatment, the tail gas rises to the conical plate 9. The conical plate 9, the fixed column 10, and the conical block 11 are all made of heat-conducting materials. Water vapor is generated during the desulfurization and denitrification process. When it encounters the conical plate 9, the fixed column 10, and the conical block 11, the heat dissipation temperature decreases and condensation occurs. The water droplets fall on the inclined plate 12 and are discharged through the drain pipe 13.
