Description

Technical Field

[0001] The invention relates to the technical field of tail gas washing equipment, in particular to a glass fiber reinforced plastic tail gas washing tower. Background Art

[0002] FRP tail gas scrubbers are widely used in the chemical, petroleum and environmental protection fields due to their excellent corrosion resistance, light weight, high strength and long service life. They can effectively treat acidic, alkaline or other highly corrosive industrial tail gases, ensure purification efficiency and reduce maintenance costs. The flexibility of FRP materials makes the scrubber design more adaptable and can be customized according to the processing requirements to meet the needs of different processes.

[0003] A glass fiber reinforced plastic exhaust gas washing cyclone tower is disclosed in the patent publication number CN213433831U. The tower body is made of glass fiber reinforced plastic, and an exhaust gas inlet is provided on the side of the tower body, an exhaust port is provided on the top of the tower body, and a sewage outlet is provided at the bottom of the tower body. The sewage outlet of the tower body is connected to a sewage valve. The absorber includes a bracket, a conical plate and an annular inclined plate. The bracket is fixedly installed in the tower body above the exhaust gas inlet, and the conical plate and the annular inclined plate are fixedly installed on the bracket. The annular inclined plate is sleeved on the outer side of the conical plate layer by layer, which effectively improves the exhaust gas absorption effect and reduces the content of harmful substances in the exhaust gas, which is very environmentally friendly.

[0004] The prior art has the following defects:

[0005] The exhaust gas circulation effect in the tower is not good: good exhaust gas circulation in the tower can help maintain the balance in the tower and avoid operational fluctuations caused by gas retention or uneven flow. The existing packing layer is generally a pile of packing, and the exhaust gas cannot circulate well in the piled packing, resulting in excessive or small local flow, affecting the overall circulation effect. Therefore, it is necessary to set up a layered structure that can evenly guide the flow, improve the circulation effect, enhance the contact between gas and liquid, and make pollutant removal more thorough, thereby improving the exhaust gas treatment efficiency and achieving the effect of improving production continuity and stability.

[0006] Unable to adjust the circulation environment according to different washing needs: Existing washing towers are generally unable to change the environment in which the exhaust gas circulates. The removal efficiency of certain specific pollutants will be reduced, resulting in unstable treatment effects. It will also lead to excessive washing in some cases, wasting resources, or insufficient effective treatment of exhaust gas, affecting the overall operational flexibility and response speed. Therefore, it is necessary to set up a structure that can adjust the circulation environment to change the contact area and contact time between the exhaust gas and the washing liquid, so as to adapt to different washing needs and achieve the effect of improving the stability and adaptability of exhaust gas treatment. Summary of the invention

[0007] In view of the problems in the prior art such as poor exhaust gas circulation effect in the tower and inability to adjust the circulation environment according to different washing requirements, a glass fiber reinforced plastic exhaust gas washing tower is proposed.

[0058] By moving the clamping plate 541 , the arc-shaped shelves 621 in each notch groove 542 can be turned over at the contact position between the fixing ear 622 and the swing bolt 614 , thereby playing the role of adjusting the arc-shaped shelves 621 .

[0059] Reference Fig. 9 - Fig.10 The synchronization component 51 includes an adjusting threaded rod 512 and two driven threaded rods 517 which are rotatably connected between the adjusting frame 52 and the protective cover 53. One end of the adjusting threaded rod 512 is fixedly connected to an adjusting handwheel 511, and the adjusting handwheel 511 is arranged outside the tower body component 2. The outer wall of the adjusting threaded rod 512 is fixedly connected to a transmission bevel gear 515, and the outer walls of the two driven threaded rods 517 are fixedly connected to driven bevel gears 516. The transmission bevel gear 515 and the two driven bevel gears 516 are both arranged inside the protective cover 53. The transmission bevel gear 515 is respectively meshed with the two driven bevel gears 516.

[0063] Through the tower body assembly 2 , the tail gas enters the interior of the FRP tower body 21 from the air inlet pipe 3 for washing. After washing, the gas is defogged by the demister 23 and then discharged from the exhaust pipe 24 .

[0065] Through the spray assembly 4 , the washing liquid is sprayed out from the nozzle 43 for washing, and the washing is circulated through the circulation pump 41 and the circulation pipeline 42 .

[0066] During use, the exhaust gas enters the interior of the FRP tower body 21 from the air inlet pipe 3, and the exhaust gas enters each branch chamber 63 in the ventilation chamber 64 connected to the air inlet pipe 3. The exhaust gas in the branch chamber 63 shuttles freely in the ventilation openings 623 on the arc-shaped shelf 621, which enhances the circulation effect and makes the pollutant removal more thorough, thereby improving the exhaust gas treatment efficiency. Then the spray assembly 4 is operated for washing. After washing, the gas is defogged by the demister 23 and discharged from the exhaust pipe 24. When it is necessary to adjust the washing demand to fast washing, the arc-shaped shelf 621 is flipped at the contact position between the fixed ear 622 and the swing bolt 614, and the upper part of the arc-shaped shelf 621 is tilted outward in the corresponding swing groove 613, and the lower part of the arc-shaped shelf 621 is tilted in the corresponding swing groove 6 13 is tilted inwards.

When changing the shape of the arc-shaped shelf 621 still cannot meet the washing conditions, fillers can be placed in the diversion cavity 63 to increase the contact area between the exhaust gas and the washing liquid. In order to avoid the accumulation of fillers causing excessive or insufficient local flow and affecting the overall circulation effect, the hand wheel 511 can be repeatedly operated to drive the arc-shaped shelf 621 to swing, thereby unblocking the circulation environment and achieving the effect of improving production continuity and stability.

[0067] Working principle of the present invention:

[0068] During operation, the exhaust gas enters the interior of the FRP tower body 21 from the air inlet pipe 3, and enters each diversion chamber 63 in the ventilation chamber 64 connected to the air inlet pipe 3. The exhaust gas in the diversion chamber 63 shuttles freely in the ventilation opening 623 on the arc-shaped shelf 621, thereby enhancing the circulation effect and ensuring the contact area between the exhaust gas and the washing liquid. Then the washing liquid is sprayed out by the nozzle 43 for washing, and circulated washing is carried out through the circulation pump 41 and the circulation pipeline 42. Finally, the washed gas is defogged by the demister 23 and discharged from the exhaust pipe 24.

[0069] For some tail gas with less impurities, when the washing requirement needs to be adjusted to fast washing, the angle of the arc-shaped shelf 621 can be adjusted by operating the adjustment mechanism 5 so that the upper part of the arc-shaped shelf 621 tilts outward, thereby accelerating the circulation speed of the gas.

[0070] The operating adjustment hand wheel 511 drives the adjustment threaded rod 512 to rotate, and the clamping plates 541 on the left-handed thread groove 513 and the right-handed thread groove 514 at both ends of the adjustment threaded rod 512 move in opposite directions in the corresponding adjustment frame 52 respectively, and because the transmission bevel gear 515 on the adjustment threaded rod 512 is engaged with the driven bevel gear 516 on the driven threaded rod 517, the clamping plates 541 on the two driven threaded rods 517 also move in opposite directions in the corresponding adjustment frame 52.

[0071] As a result, the corresponding clamping plates 541 inside each adjustment frame 52 are moved outward, and the arc-shaped shelves 621 in each notch groove 542 are driven to flip at the contact position between the fixing ear 622 and the swing bolt 614, and the upper part of the arc-shaped shelf 621 is tilted outward in the corresponding swing groove 613, and the lower part of the arc-shaped shelf 621 is tilted inward in the corresponding swing groove 613, thereby playing a role in adjusting the circulation environment.

[0072] For some exhaust gases with more impurities, when the washing requirement needs to be adjusted to slow washing, the angle of the arc-shaped shelf 621 can be adjusted by operating the adjustment mechanism 5, so that the upper part of the arc-shaped shelf 621 is tilted inward in the corresponding swing groove 613, and the lower part of the arc-shaped shelf 621 is tilted outward in the corresponding swing groove 613, thereby achieving the effect of increasing the contact time between the exhaust gas and the washing liquid.

[0073] When changing the shape of the arc-shaped shelf 621 still cannot meet the washing conditions, fillers can be placed in the diversion chamber 63 to increase the contact area between the exhaust gas and the washing liquid. In order to avoid the accumulation of fillers causing excessive or insufficient local flow and affecting the overall circulation effect, the arc-shaped shelf 621 can be driven to swing by repeatedly operating the adjustment hand wheel 511, thereby unblocking the circulation environment and achieving the effect of improving production continuity and stability.
