Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When the desulfurization tower device is used, firstly, the circulating pump is started, liquid enters the cylindrical cavity through the water pipe and is discharged through the water spray holes, in the process, the water spray holes are relatively large, dust is not easy to block the water spray holes, then the motor is started, industrial waste gas enters through the air inlet holes, the central shaft rotates under the driving of the motor, so that the blocking strip performs centrifugal motion to be close to the water spray holes to block the middle parts of the water spray holes, the liquid can only be sprayed out through the edges of the water spray holes, the water spray holes are reduced, liquid drops sprayed out of the water spray holes are smaller, the contact area of the liquid drops and the industrial waste gas is favorably increased, and the desulfurization efficiency is improved; in addition, the cylinder rotates to drive the liquid inside to do centrifugal motion, and the kinetic energy of the liquid drop spraying is increased.
As a better implementation mode, referring to fig. 1, a water eliminator 17 is further arranged above the spraying structure, a heat exchange pipe 18 is arranged above the water eliminator, the heat exchange pipe penetrates through the desulfurization tower body, the water eliminator can use an existing structure and is used for reducing the discharge of moisture in gas through an air outlet, and when the heat exchange pipe is used, cooling water can be provided to reduce the temperature of the rising gas after passing through the heat exchange pipe and to be closer to the temperature outside the desulfurization tower, so that the influence of a large amount of water mist on the air outlet caused by a large temperature difference between the temperature of hot gas discharged from the air outlet and the temperature outside the desulfurization tower body can be prevented.
As a modification, referring to fig. 4, a water eliminator 17 is further disposed above the spraying structure, and a heat exchange pipe 18 is disposed below the water eliminator and penetrates through the desulfurization tower body. When the heat exchange tube is used, gas such as high-temperature water vapor or hot water can be provided, so that liquid drops are quickly vaporized when the rising gas passes through the heat exchange tube, ions in the liquid drops are attached to the heat exchange tube, and a reagent in the liquid drops is prevented from diffusing to the outside of the desulfurizing tower body along with the gas; when the heat exchange tube is used, low-temperature water or a refrigerant can be provided, so that liquid drops are quickly liquefied and fall down when rising gas passes through the heat exchange tube, and the working pressure of the water eliminator is reduced; of course, in actual use, the heat medium or the cold medium can be used according to the external environment temperature, and the downstream of the heat exchange pipe is connected to a user so as to facilitate the secondary use of the medium, such as the cold medium can be used in summer and the heat medium can be used in winter.
As a modification, referring to fig. 5, a water eliminator 17 is further disposed above the spray structure, and heat exchange tubes 18 are disposed above and below the water eliminator and penetrate through the desulfurization tower body. The heat exchange tube of top provides the cold medium such as cooling water when using, and the cold medium makes the gas that rises reduce through temperature behind the heat exchange tube, more is close the outside temperature of desulfurizing tower to can prevent that the great production a large amount of water smoke of the steam temperature of discharging and the outside temperature difference of desulfurizing tower body from influencing the air-out in air outlet department. The lower heat exchange pipe uses a cold medium or a heat medium.
