Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, specifically, it relates to a circulating spray acid mist absorber. Background Technology

[0002] In numerous industrial production and environmental protection processes, spray systems are widely used in various scenarios, including the spraying of liquids to achieve functions such as cooling, washing, and absorption.

[0003] However, in the process of acid mist absorption, a circulating spraying method is usually adopted, so that the specific absorbent liquid is atomized through the nozzle and comes into full contact with the acid mist, thereby achieving the absorption and purification of acid mist. However, over time, after the nozzle has been used for a long time, a series of chemical reactions will occur when the filtrate interacts with the acid mist, generating some salts or other compounds with low solubility, which will crystallize and cause the nozzle to become clogged. Furthermore, after the nozzle is no longer in use, the filtrate may concentrate at a certain point and fall, significantly reducing the contact area between the filtrate and the acid mist, thus leading to a decrease in the filtration efficiency of acid mist.

[0004] To address the aforementioned problems, this application proposes a circulating spray acid mist absorber. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a circulating spray acid mist absorber to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A circulating spray acid mist absorber includes a housing, and a spray structure is provided inside the housing;

[0008] The housing is equipped with a filter structure.

[0009] The spray structure includes a liquid storage tank fixedly connected to the bottom of the outer shell. A liquid outlet pipe is fixedly connected through the outer wall of the outer shell. A flow collector is fixedly connected to one end of the liquid outlet pipe. A bracket is fixedly connected to the inner wall of the flow collector. A spiral blade is rotatably connected to the bracket. A column is fixedly connected to the bottom of the bracket. A dispersion disc is slidably connected to the outer wall of the column. A sliding column is fixedly connected to the top of the dispersion disc. A ramp is provided at the end of the sliding column near the spiral blade. A spring is fixedly connected to the bottom of the dispersion disc. The end of the spring away from the dispersion disc is fixedly connected to the outer wall of the column.

[0010] Preferably, the filtration structure includes a packing layer fixedly connected to the inner wall of the outer shell, and a sedimentation plate fixedly connected to the inner wall of the storage tank. By setting the packing layer and the sedimentation plate, the packing layer facilitates increasing the contact time between the filtrate and the acid mist, thereby increasing the reaction time, and the sedimentation plate facilitates the buffering and sedimentation of solid impurities in the filtrate.

[0011] Preferably, a base is fixedly connected to the outer wall of the storage tank, and a circulation pump is fixedly connected to the top of the base. The output end of the circulation pump is fixedly connected to the outlet pipe, and the input end of the circulation pump is fixedly connected to the inlet pipe. The inlet pipe is located inside the storage tank. By setting up the base, circulation pump, outlet pipe, and inlet pipe, it is convenient to circulate the filtered liquid inside the storage tank.

[0012] Preferably, a blocking ring is fixedly connected to the outer wall of the sedimentation plate, and an inclined angle is provided between the blocking ring and the sedimentation plate. The sedimentation plate is located directly above the liquid inlet pipe. By setting an inclined angle between the blocking ring and the sedimentation plate, it is easier to further intercept solid impurities in the filtrate and reduce the entry of solid impurities into the interior of the storage tank.

[0013] Preferably, a guide plate is fixedly connected to the top of the spiral blade. The cross-section of the guide plate is conical. By setting the guide plate, it is convenient to diffuse the filtrate.

[0014] Preferably, the outer wall of the outer shell is provided with a cleaning port, the top of the liquid storage tank is fixedly connected to a liquid replenishment pipe, and the top of the liquid storage tank is fixedly connected to an air inlet pipe. By providing a cleaning port, it is convenient to observe and clean the inside of the equipment.

[0015] In summary, the technical effects and advantages of this utility model are as follows: This circulating spray acid mist absorber, through the coordinated use of the support, spiral blades, column, and dispersion disc, facilitates the dispersion of the filtrate, avoids prolonged use of the nozzle, and thus prevents crystallization from forming on the nozzle. Furthermore, the dispersion of the filtrate increases its coverage area, preventing a decrease in filtration efficiency due to nozzle disuse. The coordinated use of the spiral blades, spring, and sliding column facilitates the up-and-down reciprocating movement of the dispersion disc, increasing the dispersion force on the filtrate and thereby improving its coverage area.

[0016] The combination of sedimentation plate and baffle ring facilitates the sedimentation and filtration of solid impurities in the filtrate, preventing solid impurities from entering the circulation pump during the recycling process and thus avoiding damage to the circulation pump.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-4 A circulating spray acid mist absorber includes a housing 1, and a spray structure 2 is provided inside the housing 1;

[0032] The housing 1 has a filter structure 3 inside;

[0033] The spray structure 2 includes a liquid storage tank 201 fixedly connected to the bottom of the outer shell 1. A liquid outlet pipe 204 is fixedly connected through the outer wall of the outer shell 1. One end of the liquid outlet pipe 204 is fixedly connected to a flow collector 205, which is located inside the outer shell 1 and at its center. A support 206 is fixedly connected to the inner wall of the flow collector 205. A spiral blade 208 is rotatably connected to the support 206, with a portion of the spiral blade 208 located inside the flow collector 205. A column 209 is fixedly connected to the bottom of the support 206, located at its center. A dispersion disc 210 is slidably connected to the outer wall of the column 209. The outer side wall of the dispersion disk 210 is attached to the inner side wall of the outer shell 1. A sliding column 212 is fixedly connected to the top of the dispersion disk 210. There are two sliding columns 212. The two sliding columns 212 pass through the bottom of the support 206 and extend to the other side of the support 206. The ends of the two sliding columns 212 near the spiral blade 208 are provided with slopes, and the direction of the slopes is the same as the rotation direction of the spiral blade 208. When the spiral blade 208 rotates, it can squeeze the two sliding columns 212, thereby pushing the dispersion disk 210. A spring 211 is fixedly connected to the bottom of the dispersion disk 210. The end of the spring 211 away from the dispersion disk 210 is fixedly connected to the outer side wall of the column 209.

[0034] During use, the filtrate enters the interior of the collection hood 205 along the outlet pipe 204, where it is concentrated to prevent splashing after contact with the spiral blades 208. When the filtrate comes into contact with the spiral blades 208, the gravity of the falling filtrate is converted into the rotational force of the spiral blades 208, thus driving them to rotate. As the spiral blades 208 rotate, they compress the two sliding columns 212, intermittently pushing the dispersing disc 210 to move. As the dispersing disc 210 gradually moves away from the spiral blades 208, it compresses the column 209. When the spiral blades 208 release the pressure on the two sliding columns 212, the dispersing disc 210 moves towards the spiral blades 208 under the automatic elastic force of the column 209, and disperses the falling filtrate during this movement, increasing the coverage area of ​​the filtrate and preventing a reduction in coverage area when the spray is not used.

[0035] Reference Figure 5 and Figure 6 The filter structure 3 includes a packing layer 301 fixedly connected to the inner wall of the outer shell 1, and a sedimentation plate 302 fixedly connected to the inner wall of the liquid storage tank 201. The sedimentation plate 302 is located below the packing layer 301, and the cross-section of the sedimentation plate 302 is an inverted trapezoid, that is, the top opening of the sedimentation plate 302 is larger than the bottom opening of the sedimentation plate 302.

[0036] Reference Figure 1 and Figure 5 A base 202 is fixedly connected to the outer wall of the storage tank 201. A circulation pump 203 is fixedly connected to the top of the base 202. The circulation pump 203 is connected to an external power supply. The output end of the circulation pump 203 is fixedly connected to the outlet pipe 204. The input end of the circulation pump 203 is fixedly connected to the inlet pipe 213. The inlet pipe 213 is located inside the storage tank 201. During use, the circulation pump 203 transfers the filtered liquid inside the storage tank 201.

[0037] Reference Figure 6 A baffle ring 303 is fixedly connected to the outer wall of the sedimentation plate 302. Multiple baffle rings 303 are evenly distributed on the outer wall of the sedimentation plate 302, and the spacing between the multiple baffle rings 303 is the same. Each baffle ring 303 is inclined at an angle to the sedimentation plate 302. When the filtrate flows through the sedimentation plate 302, due to the inclined angle of the sedimentation plate 302 and the multiple baffle rings 303 on its outer wall, as well as the inclined angle between the multiple baffle rings 303 and the sedimentation plate 302, solid impurities in the filtrate will enter the inclined angle between the multiple baffle rings 303 and the sedimentation plate 302 due to gravity, and will be blocked by the baffle rings 303. This prevents solid impurities from entering the interior of the storage tank 201 and causing damage to the circulation pump 203. The sedimentation plate 302 is located directly above the inlet pipe 213.

[0038] Reference Figure 3 A guide plate 207 is fixedly connected to the top of the spiral blade 208. The cross-section of the guide plate 207 is conical. The guide plate 207 facilitates changing the flow direction of the filtrate discharged from the outlet pipe 204, thereby increasing the contact area between the filtrate and the spiral blade 208.

[0039] Reference Figure 1 The outer wall of the outer shell 1 is provided with a cleaning port 4, the top of the liquid storage tank 201 is fixedly connected to a liquid replenishment pipe 5, and the top of the liquid storage tank 201 is fixedly connected to an air inlet pipe 6.

[0040] Working principle: During operation, the circulating pump 203 transfers the filtrate inside the storage tank 201. The filtrate enters the collector 205 along the outlet pipe 204, where it is concentrated to prevent splashing after contact with the spiral blades 208. When the filtrate comes into contact with the spiral blades 208, the gravity of the falling filtrate is converted into the rotational force of the spiral blades 208, thus driving them to rotate. As the spiral blades 208 rotate, they compress the two sliding columns 212, intermittently pushing the dispersing disc 210 to move. As the dispersing disc 210 gradually moves away from the spiral blades 208, it will move in opposite directions. When the spiral blades 208 release the pressure on the two sliding columns 212, the dispersing disc 210 moves towards the spiral blades 208 under the automatic elastic force of the column 209. During the movement, it disperses the falling filtrate, increases the coverage area of ​​the filtrate, and avoids the reduction of the coverage area of ​​the filtrate due to the lack of spraying. When the filtrate flows through the sedimentation disc 302, the solid impurities in the filtrate will enter the inclined angle between the multiple blocking rings 303 and the sedimentation disc 302 due to gravity, and will be blocked by the blocking rings 303, thus preventing the solid impurities from entering the interior of the storage tank 201 and causing damage to the circulation pump 203.
