Description
Technical Field
[0001] This utility model belongs to the technical field of spray scrubbing towers, specifically a spray scrubbing tower with an automatic dosing system. Background Technology
[0002] A spray scrubbing tower is a gas purification and treatment device. It is an improvement on the floating packing layer gas purifier and is widely used for industrial waste gas purification and dust removal. The spray scrubbing tower utilizes the contact between gas and liquid to transfer pollutants in the gas to the liquid, and then separates the clean gas from the polluted liquid to achieve the purpose of purifying the air. The waste gas is treated by gas-liquid reverse absorption method after passing through the scrubbing tower. That is, the liquid is sprayed down from the top of the tower in a mist form, and the waste gas is treated by gas-liquid contact through the tower body. This treatment can cool the waste gas, condition the gas and remove particles. After being treated by demisting, it is discharged into the atmosphere.
[0003] Existing scrubbing towers generally use manual dosing. For example, when adding chemicals to acid and alkali scrubbing towers, workers need to manually pour the chemicals into the water tank, which wastes workers' time and is labor-intensive. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Example 1, by Figure 1 The present invention relates to a spray scrubbing tower with an automatic dosing system, comprising a tower body 1, a dosing mechanism 2 and a stirring mechanism 3 on the outer side of the tower body 1.
[0025] Specifically, by Figure 2-4The dosing mechanism 2 includes a dosing tank 201 located outside the tower body 1. A connecting pipe 202 is fixedly connected to the dosing tank 201, and a solenoid valve 206 is installed on the connecting pipe 202. One end of the connecting pipe 202 away from the dosing tank 201 extends into the interior of the tower body 1 and is fixedly connected to an annular nozzle 205. Two support plates 204 are symmetrically fixedly connected between the outer side of the annular nozzle 205 and the tower body 1. Multiple nozzles 203 are provided at equal angles at the bottom of the annular nozzle 205. A storage tank 2010 is located below the dosing tank 201, and the top of the storage tank 2010... A drug injection pipe 2011 and a water pump 208 are fixedly connected. A drug extraction pipe 209 is fixedly connected between the water pump 208 and the drug storage tank 2010. A drug delivery pipe 207 is fixedly connected between the water pump 208 and the drug dosing tank 201. An upper controller 2022 and a lower controller 2023 are fixedly connected to the outside of the drug dosing tank 201. A float 2024 is movably installed inside the drug dosing tank 201. A movable U-shaped rod 2014 is fixedly connected to the top of the float 2024. The movable U-shaped rod 2014 passes through the drug dosing tank 201 and is movably connected to the drug dosing tank 201. A sleeve plate 2015 is fixedly sleeved on the outer middle part of the 014. A fixed U-shaped rod 2016 is fixedly connected to the top of the dosing tank 201. The sleeve plate 2015 is movably sleeved on the outer side of the fixed U-shaped rod 2016. A sleeve disc 2012 is fixedly sleeved on the outer side of the fixed U-shaped rod 2016. Two return springs 2013 are symmetrically fixedly connected between the top of the sleeve disc 2012 and the bottom of the sleeve plate 2015. Both return springs 2013 are sleeved on the outer side of the fixed U-shaped rod 2016. A top post 2019 and a bottom post 2019 are fixedly installed on the top and bottom of the sleeve plate 2015, respectively. The top of the column 2020 and the sleeve plate 2012 is provided with a lower pressure sensor 2021 located below the bottom column 2020. A sleeve block 2017 is fixedly sleeved on the middle of the outer side of the fixed U-shaped rod 2016. The bottom of the sleeve block 2017 is provided with an upper pressure sensor 2018 located above the top column 2019. The upper pressure sensor 2018 is electrically connected to the upper controller 2022. The upper controller 2022 is electrically connected to the solenoid valve 206. The lower pressure sensor 2021 is electrically connected to the lower controller 2023. The lower controller 2023 is electrically connected to the water pump 208.
[0026] First, the water pump 208 is started, drawing the medicine from the storage tank 2010 through the extraction pipe 209 and transferring it through the delivery pipe 207 into the dosing tank 201. At this time, the water level in the dosing tank 201 rises, causing the float 2024 to move upwards. This, in turn, causes the movable U-shaped rod 2014 to move the sleeve 2015 upwards along the fixed U-shaped rod 2016. Both return springs 2013 are stretched, causing the top column 2019 to rise. When the top column 2019 presses against the upper pressure sensor 2018, the upper pressure sensor 2018 transmits an electrical signal to the upper controller 2022. Simultaneously, the upper controller 2022 controls the solenoid valve 206 to open, allowing the medicine in the dosing tank 201 to flow through the connecting pipe 20... 2. The solution enters the annular nozzle 205 and is sprayed out from each nozzle 203 to achieve spray treatment of the exhaust gas. As the reagent in the dosing tank 201 is continuously used, the water level drops. The two reset springs 2013 reset and drive the sleeve plate 2015 to slide down along the fixed U-shaped rod 2016. The movable U-shaped rod 2014 drives the float plate 2024 to move down and drives the bottom column 2020 to descend until it squeezes the lower pressure sensor 2021. At this time, the lower pressure sensor 2021 transmits an electrical signal to the lower controller 2023. At the same time, the lower controller 2023 controls the water pump 208 to start, and re-extracts the reagent in the storage tank 2010 into the dosing tank 201, finally completing the automatic addition of the reagent.
[0027] Specifically, by Figure 5 The stirring mechanism 3 includes an L-shaped seat 301 fixed to the top of the medicine storage tank 2010. A stirring motor 302 is fixedly connected to the L-shaped seat 301. A stirring shaft 304 is fixedly connected to the stirring motor 302. The bottom end of the stirring shaft 304 extends into the interior of the medicine storage tank 2010 and is fixedly connected to a connecting frame 305. A stirring plate 306 is fixedly connected to the bottom of the connecting frame 305. The stirring plate 306 is in contact with the inner bottom wall of the medicine storage tank 2010. Multiple stirring rods 307 are evenly fixedly connected to the outside of the stirring shaft 304. A sealing bearing 303 is provided at the top of the medicine storage tank 2010. The sealing bearing 303 is sleeved on the outside of the stirring shaft 304. The sealing bearing 303 ensures the sealing of the medicine storage tank 2010.
[0028] In use, first start the stirring motor 302, which drives the stirring shaft 304 to rotate. The connecting frame 305 drives the stirring plate 306 to rotate, preventing the medicine in the storage tank 2010 from settling. Then, the stirring rod 307 rotates to stir the medicine, ensuring that the medicine in the storage tank 2010 is fully mixed.
