Description
Technical Field
[0001] The utility model belongs to the technical field of separation devices, in particular to a wet desulfurization tower for sintering flue gas. Background Art
[0002] With the increasing requirements for environmental protection, the desulfurization treatment of sintering flue gas has become a key link. Traditional desulfurization towers have many problems in treating sintering flue gas, such as low desulfurization efficiency, high energy consumption, and easy corrosion of equipment. Wet desulfurization towers are widely used in sintering flue gas treatment due to their efficient desulfurization capabilities. They can effectively remove pollutants such as sulfur dioxide in flue gas and reduce the impact on the environment. However, in actual operation, wet desulfurization towers still face challenges such as scaling, blockage, and corrosion. Further optimization of design and improvement of processes are needed to improve desulfurization efficiency and stability to meet environmental protection requirements.
[0003] During the use of the existing wet desulfurization tower for sintering flue gas, the use of ammonia water for desulfurization will cause the ammonia water to volatilize. The volatilized ammonia water will be discharged from the device along with the flue gas after desulfurization. This not only causes a waste of ammonia resources, but also pollutes the working environment, affects the air quality, and corrodes the equipment, reduces the equipment life, and increases maintenance costs. Utility Model Content
[0004] The utility model aims to provide a wet desulfurization tower for sintering flue gas. By setting an ammonia removal mechanism, the utility model solves the problem that in the existing wet desulfurization tower for sintering flue gas, the desulfurization with ammonia water will cause the ammonia water to volatilize during use, and the volatilized ammonia water will be discharged from the flue gas after the desulfurization is completed, which not only causes a waste of ammonia resources, but also pollutes the working environment, affects the air quality, and corrodes the equipment, reduces the equipment life, and increases the maintenance cost.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model is a wet desulfurization tower for sintering flue gas, comprising a desulfurization box, on which an ammonia removal mechanism and an impurity removal mechanism are arranged;
[0007] A nozzle is fixedly connected to the inner wall at the top of the desulfurization box, and the ammonia removal mechanism includes a wind box connected to the right side of the desulfurization box, a partition is fixedly connected to the right side of the wind box, a water tank is arranged on the right side of the partition, and an exhaust port 1 is connected to the top of the water tank.
[0008] Furthermore, the right side of the partition is connected to an exhaust port 2, the right side of the exhaust port 2 extends into the water tank, and a condenser is sleeved on the outer wall of the water tank.
[0009] Furthermore, a heat-insulating shell is fixedly connected to the bottom of the water tank, a circulating water pump is fixedly connected to the inner wall of the heat-insulating shell, the top of the circulating water pump is connected to the condenser, and the left end of the condenser is connected to the circulating water pump.
[0010] Furthermore, the impurity removal mechanism includes an air inlet connected to the left side of the desulfurization box, and a filter plate is fixedly connected to the inner wall of the air inlet.
[0011] Furthermore, a connecting shell is fixedly connected to the inner wall of the bottom of the air inlet, and a sliding block is slidably connected to the inner wall of the connecting shell.
[0012] Furthermore, a motor is fixedly connected to the inner wall of the air inlet, a rotating shaft is rotatably connected to the top inner wall of the connecting shell, the bottom of the rotating shaft rotates and extends outside the connecting shell, and the output shaft of the motor is fixedly connected to the rotating shaft through a coupling.
[0013] Furthermore, a protrusion is fixedly connected to the outer wall of the rotating shaft, and the protrusion is adapted to the slider. A spring telescopic rod is fixedly connected to the right inner wall of the connecting shell, and the left side of the spring telescopic rod is fixedly connected to the slider.
[0014] The utility model has the following beneficial effects:
[0015] 1. By setting up an ammonia removal mechanism, when the flue gas enters the desulfurization box, the nozzle can be started to spray ammonia water to react with the sulfur in the flue gas, thereby removing the sulfur. At this time, the bellows can be started to discharge the desulfurized flue gas in the desulfurization box through the partition from the second exhaust port into the water tank to contact the water in the water tank. At this time, the circulating water pump can be started to pump the condensate into the condenser pipe to cool the water in the water tank. At this time, the ammonia contained in the flue gas will dissolve in the water with a lower temperature, thereby separating the ammonia from the flue gas. At this time, the treated flue gas will be discharged from the exhaust port 1, so that the ammonia water mixed in the desulfurized flue gas can be removed, and the volatilized ammonia water can be prevented from being discharged from the device along with the desulfurized flue gas. This not only avoids the waste of ammonia resources, but also maintains the safety and stability of the working environment, thereby avoiding corrosion of the device and reducing maintenance costs.
[0016] 2. By setting up an impurity removal mechanism, the flue gas that needs to be desulfurized can be transported to the device through the air inlet. Under the action of the ammonia removal mechanism, the particulate impurities in the flue gas will be removed. When the particulate impurities adhere to the filter plate, the motor can be started to rotate its output shaft. When the output shaft of the motor rotates, it will drive the protrusion through the rotating shaft. At this time, the slider will periodically apply pressure to the spring telescopic rod under the action of the protrusion, causing it to elastically deform and generate elastic force. When the pressure disappears, the slider will oscillate and clean the filter plate under the action of this elastic force to avoid particles clogging the filter plate and affecting the filtration efficiency. This allows the flue gas before entering the desulfurization tower to be filtered and the solid particles therein to be removed to avoid clogging when entering the device. There is no need for staff to clean the equipment for a long time, thereby reducing the burden on staff.
[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
