Description

Technical Field

[0001] The utility model relates to the technical field of anti-scaling equipment, in particular to a descaling device and a deacidification tower. Background Art

[0002] The deacidification tower is used to remove acidic gases from flue gas. Since there are many impurities and high viscosity in flue gas, the medium that has not fully reacted will reach the inner wall of the deacidification tower with the airflow and scale on the inner wall of the deacidification tower, resulting in an increase in the load of the deacidification tower and a reduction in the operating life of the deacidification tower. In the related art, gas is blown to the wall of the deacidification tower to form a gas protective layer on the wall of the deacidification tower to avoid scaling of the wall of the deacidification tower.

[0003] However, the gas protective layer will exert a large pressure on the wall of the deacidification tower, which may easily cause local deformation of the deacidification tower and reduce the life of the equipment. In addition, the unstable airflow of the flue gas makes it difficult to control the airflow forming the gas protective layer, resulting in poor anti-scaling effect on the wall of the deacidification tower, which requires production to be stopped to clean the scale on the inner wall of the deacidification tower.

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0029] The descaling device 110 and the deacidification tower 100 according to the embodiment of the utility model are described below in conjunction with the accompanying drawings.

[0030] like Figure 1 and Figure 3As shown, the descaling device 110 of the embodiment of the utility model includes a vibrator 1 and a vibrating rod 2. The vibrator 1 can generate vibrations. The vibrating rod 2 is connected to the vibrator 1 so as to be driven by the vibrator 1 to generate vibrations. The vibrating rod 2 is used to extend into the deacidification tower 100, and the vibrating rod 2 is used to cooperate with the deacidification tower 100 to knock the deacidification tower wall.

[0031] The vibrator 1 drives the vibrating rod 2 to vibrate, and the vibrating rod 2 strikes the deacidification tower wall during the vibration process to knock off the scale attached to the deacidification tower wall, thereby cleaning the scale attached to the deacidification tower wall.

[0032] During the cleaning process of the deacidification tower 100 , the pressure of the vibration rod 2 on the wall of the deacidification tower is relatively small, thereby avoiding local deformation of the deacidification tower 100 and avoiding reducing the service life of the deacidification tower 100 .

[0033] In addition, the descaling device 1 of the embodiment of the utility model can clean the scale attached to the wall of the deacidification tower 100 when the deacidification tower 100 is performing the deacidification process, avoid frequent shutdown of the deacidification tower 100, and improve the operating stability of the deacidification tower 100.

[0034] The descaling device 1 of the embodiment of the utility model applies less pressure to the deacidification tower wall when descaling the deacidification tower 100, thereby avoiding local deformation of the deacidification tower 100 and thus avoiding reducing the life of the deacidification tower 100. In addition, the descaling device 1 of the embodiment of the utility model can clean the scale attached to the deacidification tower wall when the deacidification tower 100 is performing the deacidification process, thereby avoiding frequent shutdown of the deacidification tower 100 and improving the stability of the operation of the deacidification tower 100.

[0035] like Figure 1 As shown, the deacidification tower 100 of the embodiment of the utility model includes a deacidification tower body 120, a rotary atomizer 130 and a descaling device 110 as in the above embodiment. The deacidification tower body 120 is provided with a spiral flue gas inlet 121 for introducing flue gas, a flue gas outlet 122 for discharging flue gas and an ash outlet 123 for discharging ash; the rotary atomizer 130 is provided on the deacidification tower body 120, and the rotary atomizer 130 is used to spray lime slurry into the deacidification tower body 120, and the rotary atomizer 130 cooperates with the spiral flue gas inlet 121 to mix the flue gas with the lime slurry; the descaling device 110 is provided on the deacidification tower body 120, and the vibration rod 2 is used to extend into the deacidification tower body 120, and the vibration rod 2 cooperates with the body to knock the wall of the deacidification tower body 120.

[0036] Since the temperature in the deacidification tower 100 is relatively high, some viscous substances are easily solidified. When the solidified viscous substances are struck by the vibration rod 2, they are easily cracked and fall off from the wall of the deacidification tower, which further facilitates the removal of scale.

[0037] The deacidification tower 100 of the embodiment of the utility model includes the descaling device 1 of the above embodiment.

The deacidification tower 100 of the embodiment of the utility model can clean the scale attached to the deacidification tower wall during the deacidification process, avoid frequent shutdown of the deacidification tower 100, and improve the stability of the operation of the deacidification tower 100. In addition, due to the high temperature in the deacidification tower 100, some viscous substances are easy to solidify, and the solidified viscous substances are easy to crack and fall off from the deacidification tower wall when being struck by the vibration rod 2, which further facilitates the removal of scale.

[0038] like Figure 2 As shown, in some embodiments, a plurality of descaling devices 110 are provided, and the plurality of descaling devices 110 are evenly spaced along the circumference of the deacidification tower body 120 to remove scale from the deacidification tower wall from multiple angles.

[0039] In some embodiments, the distance between the bottom end surface of the vibration rod 2 and the top wall of the deacidification tower 100 in the up and down directions is 2 meters to 5 meters, so as to improve the descaling effect of the vibration rod 2.

In other words, the knocking section 21 located at the contact position indirectly contacts the inner wall of the deacidification tower 100 through the vibration cylinder 3.
