[0002] Many industrial processes such as coal-fired power generation, steel smelting, waste incineration etc. can produce a large amount of flue gas, which contains sulfur dioxide. If these pollutants are directly discharged into the atmosphere without treatment, it will cause serious air pollution.

[0003] Part of the traditional deacidification tower introduces flue gas into the inside of the deacidification tower. The flue gas rises through the filler layer that receives the spray detergent. The flue gas contacts the detergent, so that the alkaline substances in the scrubbing liquid fully react with the sulfur dioxide gas in the flue gas, and at this time the deacidification work is completed.

[0004] There are some problems. If the flue gas flow is too large, it will cause the flue gas to stay in the deacidification tower for a short time, thereby affecting the flue gas deacidification treatment work. The traditional deacidification tower does not have a device to control the flue gas flow, or needs to control the amount of flue gas introduced into the deacidification tower by artificial control to control the flue gas flow, which to some extent reduces the working efficiency of the flue gas deacidification treatment. Therefore, we propose a flue gas washing deacidification tower. UTILITY MODEL CONTENT

[0031] The working principle of the deacidification tower for flue gas washing is as follows: firstly, the worker pours the alkaline washing liquid into the inside of the washing bin 16 through the liquid supplementing pipe 161, then drives the water pump in the inside of the washing bin 16, the water pump sucks the alkaline washing liquid and sprays it out through the output port, the sprayed alkaline washing liquid passes through the washing liquid spraying pipe 19 and is sprayed out through the atomizing nozzle, at this time, the alkaline washing liquid sprayed into the inside of the washing channel 5 is in atomized state, then falls into the inside of the filler layer 9 (the filler layer 9 is a ceramic filler layer, its function is that after the flue gas enters into the inside of the filler layer 9, it enters into the irregular gaps in the inside of the ceramic filler layer, slows down the flow rate of the flue gas, increases the contact time and contact area of the flue gas and the washing liquid, fully mixes the gas and liquid phases, and further improves the efficiency of the deacidification reaction), waits for the subsequent washing of the flue gas containing sulfur dioxide, then the worker discharges the flue gas containing sulfur dioxide into the inside of the washing channel 5 through the gas conveying pipe 18, the flue gas containing sulfur dioxide enters into the tower from the bottom of the deacidification tower and flows from bottom to top, after a period of time, enters into the inside of the filler layer 9, at this time, the sulfur dioxide gas in the flue gas reacts with the alkaline substance in the washing liquid to generate corresponding salt substances, so that the removal of the acidic gas is realized, after the full contact reaction of the gas and liquid passing through the filler layer 9, the flue gas continues to flow upwards, when passing through the demister 8 in the gas discharge pipe 7, the washing liquid droplets entrained in the flue gas are separated by the demister, the corrosion to the subsequent equipment and the influence on the environment are reduced, at this time, the separated washing liquid droplets are discharged through the liquid discharge pipe 6 and are collected by the worker, in this process, the worker can control the flow rate of the flue gas passing through the inside of the washing channel 5 by driving the flow rate control mechanism 2, the worker controls the control switch group 17 to make the two motors 10 operate in opposite directions (the motor 10 on one side can also be driven alone, so that the flow rate control mechanism 2 on one side is driven alone, so that the flow rate of the flue gas is further reduced), the output shaft of the motor 10 drives the adjacent output shaft 29 to rotate, the output shaft 29 drives the two uppermost driving connecting rods 24 to rotate, at this time, the outer ends of the two uppermost driving connecting rods 24 rotate upwards at the same time, then the adjacent connecting rods 25 are dragged upwards through the adjacent pin shafts 26, the connecting rods 25 drive the uppermost shafts 23 to move upwards, the shafts 23 drive the adjacent sliders 22 to move upwards along the slide rails 21 (in this process, the connecting rods 25 are dragged upwards by the driving connecting rods 24, so that the connecting rods 25 are limited by the transverse displacement of the shafts 23, so the connecting rods 25 rotate by themselves and tend to rotate upwards, so the shafts 23 are driven to move upwards, at the same time, the angle between the inner ends of the driving connecting rods 24 and the connecting rods 25 gradually decreases, the two groups of driving connecting rods 24 and the connecting rods 25 on the lower side synchronously perform the movement, the remaining sliders 22 are driven to move upwards along the slide rails 21 through the two lower shafts 23), in the process that the sliders 22 move upwards along the slide rails 21, the gears 3 at the rear ends of the shafts 23 mesh with the adjacent rack plates 4, then the mounting blocks 27 are driven to move upwards through the shafts 23, at the same time, the inner ends of the flow rate control plates 28 rotate upwards,Further drive the inner end of the flow control plate 28 upward (in this process, the flow control plate 28 along the adjacent chute 12 upward sliding and rotating way, constantly upward extrusion adjacent baffle 13, baffle 13 extrusion along the upward movement while extruding adjacent spring 15, this process, the upper end of the guide sliding hole 131 of baffle 13 and adjacent guide column 14 sliding, in the process of rotating flow control plate 28, the lower side of the flow control plate 28 will gradually contact the outer side of the lowermost end of the chute 12, so as to cooperate with the baffle 13, prevent the flue gas out), at this time, the gap between two transversely adjacent flow control plate 28 changes, the flue gas flows upward through the gap between the flow control plate 28, and part of the flue gas is blocked by the flow control plate 28, thereby realizing the effect of controlling the flue gas flow.

[0032] It is worth noting that the motor 10 disclosed in the above embodiment can be model Y90S-4, and the control switch group 17 is provided with a control button corresponding to each of the two motors 10 and used for controlling the switch thereof.

[0033] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
