[0001] The utility model relates to the technical field of desulfurization devices, in particular to a desulfurization agent adding device in a sintering process. Background Art
[0002] The desulfurization tower is a device used to remove sulfur dioxide from flue gas. During the sintering process, the flue gas generated will be pressurized and passed into the desulfurization tower. After the flue gas comes into contact with the desulfurizer (usually lime slurry or ammonia water), the sulfur dioxide in the flue gas will be absorbed, thereby reducing pollutant emissions in the atmosphere.
[0003] The above-mentioned and existing related technologies often have the following defects: when desulfurizing the flue gas generated by sintering, the flue gas is often directly injected into the desulfurizer to make the sulfur dioxide in the flue gas contact with the desulfurizer. At this time, it is easy to cause the sulfur dioxide in the flue gas to be difficult to fully contact with the desulfurizer, resulting in poor desulfurization effect.

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] See also Figure 1-6 The utility model provides a technical solution: a desulfurizing agent adding device for a sintering process, comprising a desulfurizing tower 1, the side wall of the desulfurizing tower 1 is fixed and connected with an air inlet pipe 2 and an exhaust pipe 3, the inner wall of the desulfurizing tower 1 is provided with a filling structure 4, and the outer wall of the desulfurizing tower 1 is provided with an auxiliary structure 5.
[0032] The specific settings and functions of the filling structure 4 and the auxiliary structure 5 are described in detail below.
[0033] like Figure 2 and Figure 3 as well as Figure 4 , Figure 6 As shown, the filling structure 4 includes a water pump 401, which is fixedly connected to the desulfurization tower 1, a discharge end of the water pump 401 is fixed and connected to a discharge pipe 402, the discharge pipe 402 passes through the top of the desulfurization tower 1, one end of the discharge pipe 402 is rotatably connected to a water distribution pipe 403, the arc surface of the water distribution pipe 403 is fixed and connected to a plurality of nozzles 404, the inner wall of the desulfurization tower 1 is fixedly connected to a leakage net 405, the inlet end of the water pump 401 is fixed and connected to a liquid inlet pipe 406, the liquid inlet pipe 406 passes through the desulfurization tower 1, the leakage net 405 is horizontally arranged, and the nozzle 404 is inclined to the leakage net 405. Since the nozzle 404 is inclined to the leakage net 405, a reaction force will be generated when the desulfurizer is sprayed on the surface of the leakage net 405. At this time, the nozzle 404 will drive the water distribution pipe 403 to rotate, so that the desulfurizer can be evenly sprayed on the surface of the leakage net 405. One end of 406 is fixed and connected to an extension pipe 407, and the inner wall of the extension pipe 407 is rotatably connected to a filter screen 408, which will filter the particulate matter in the desulfurizer to prevent the particulate matter from clogging the nozzle 404. The inner wall of the extension pipe 407 is rotatably connected to a rotating rod 409, which is fixedly connected to the filter screen 408, and the arc surface of the rotating rod 409 is fixedly connected to a blade 410, which is located in the liquid inlet pipe 406. The surface of the extension pipe 407 is fixedly connected to a fluff rod 411, which is slidably connected to the filter screen 408. When the desulfurizer flows through the liquid inlet pipe 406, the blade 410 will drive the rotating rod 409 to rotate, and the rotating rod 409 will drive the filter screen 408 to rotate. At this time, the fluff rod 411 will clean the particulate matter attached to the surface of the filter screen 408 to ensure that the desulfurizer can flow through the filter screen 408 normally.
[0034] like Figure 2 and Figure 5 As shown, the auxiliary structure 5 includes a hose 51, which is fixed and connected to the desulfurization tower 1, one end of the hose 51 is fixed and connected to a hard tube 52, the outer wall of the desulfurization tower 1 is fixedly connected to a support plate 53, the support plate 53 is slidably connected to the hard tube 52, a slide plate 54 is slidably connected inside the support plate 53, the surfaces of the slide plate 54 and the support plate 53 are both provided with inclined surfaces, a leaf spring 55 is fixedly connected to the surface of the slide plate 54, one end of the leaf spring 55 is fixedly connected to the support plate 53, when the leaf spring 55 contracts, the slide plate 54 will slide in the opposite direction with the help of the pulling force of the leaf spring 55, and the leaf spring 55 can achieve the effect of automatically resetting the slide plate 54, and a transparent plate 56 is fixedly connected inside the hard tube 52, and the transparent plate 56 can facilitate the grasp of the liquid level of the desulfurizer.
[0035] Working principle: When treating the flue gas generated during the sintering process, the desulfurizer is first injected through the hard pipe 52. The desulfurizer flows through the hose 51 and enters the desulfurization tower 1. At this time, the transparent plate 56 can easily grasp the liquid level of the desulfurizer, and then the pressurized flue gas is passed into the air inlet pipe 2. After the flue gas and the desulfurizer are initially in contact, they will overflow from the desulfurizer and flow upward. At this time, the water pump 401 is started, and the water pump 401 begins to suck the desulfurizer with the help of the liquid inlet pipe 406. The desulfurizer flows through the drain pipe 402 and the water distribution pipe 403 and is discharged by the nozzle 404. Since the nozzle 404 is inclined to the filter 405, when the desulfurizer is sprayed on the surface of the filter 405, a reaction force will be generated. At this time, the nozzle 404 will drive the water distribution pipe 403 to rotate, so that the desulfurizer can be evenly distributed. Evenly spray it on the surface of the filter screen 405, and then the desulfurizer can drip evenly through the filter screen 405. In this process, the desulfurizer will come into contact with the sulfur dioxide in the flue gas that has not been completely treated, and treat the sulfur dioxide, thereby improving the desulfurization effect. In the process of the desulfurizer flowing into the liquid inlet pipe 406, the desulfurizer will contain particulate matter purified from the flue gas, and the filter screen 408 will filter the particulate matter in the desulfurizer to prevent the particulate matter from clogging the nozzle 404. When the desulfurizer flows through the liquid inlet pipe 406, the blade 410 will drive the rotating rod 409 to rotate, and the rotating rod 409 will drive the filter screen 408 to rotate. At this time, the fluff rod 411 will clean the particulate matter attached to the surface of the filter screen 408 to ensure that the desulfurizer can flow through the filter screen 408 normally.
[0036] When the desulfurizer needs to be replaced, pull the slide plate 54, then take out the hard tube 52, and then place the hard tube 52 on the ground. At this time, the desulfurizer can flow through the hose 51 and the hard tube 52 and flow out of the desulfurization tower 1. When the discharge is completed, move the hard tube 52 so that the hard tube 52 contacts the slide plate 54 and the inclined surface of the support plate 53. At this time, the hard tube 52 will squeeze the slide plate 54, and the slide plate 54 will slide along the support plate 53 and stretch the leaf spring 55. When the hard tube 52 slides into the support plate 53, the leaf spring 55 begins to shrink, and the slide plate 54 will slide in the opposite direction with the help of the pulling force of the leaf spring 55. The slide plate 54 can prevent the hard tube 52 from sliding out of the support plate 53, and the support plate 53 can support the hard tube 52. Then, the new desulfurizer can be injected into the desulfurization tower 1.
