Description

Technical Field

[0001] The utility model relates to the technical field of chemical desulfurization equipment, in particular to a powder desulfurization device. Background Art

[0002] The flue gas discharged from boilers and other equipment in the factory contains a large amount of sulfides, and the sulfides in the flue need to be desulfurized to avoid polluting the environment. The sulfide flue gas in the chimney is generally desulfurized by using desulfurizer powder. The current operation method is generally to use a blower to blow the gas containing desulfurizer powder into the chimney, so that the desulfurizer powder contacts the flue gas, and then desulfurize the flue gas under a high temperature environment to reduce pollution. However, the current operation method has certain defects and shortcomings. First, the feeding component design of the current device is unreasonable, and frequent loading is cumbersome. In addition, the feeding amount of the desulfurizer powder cannot be adjusted according to the use requirements, and the feeding speed of the desulfurizer powder cannot be adjusted. The convenience in actual use is not good. Secondly, the gas containing the desulfurizer powder is discharged into the chimney and cannot fully and evenly contact the flue gas, resulting in its general desulfurization effect, so it needs to be improved.

[0013] (3) Beneficial effects

[0014] Compared with the existing technology, the utility model provides a powder desulfurization device with the following beneficial effects:

[0015] 1. The utility model provides a feeding assembly, which consists of a silo and a feeder arranged at the bottom of the silo. The silo is used to store desulfurizer powder, and the feeder is mainly composed of a feeding pipe and a spiral feeding blade. When in use, the shaft is driven to rotate by a motor, which then causes the spiral feeding blade to rotate. The faster the spiral feeding blade rotates, the faster the feeding speed is, and vice versa. In this way, the feeding speed of the desulfurizer powder is controlled. This method can also avoid blockage when the powder is discharged, and has good use effect. This method can meet the use of the device under different requirements. When the amount of smoke in the chimney is large, the speed is increased. When the amount of smoke in the chimney is small, the feeding speed of the desulfurizer powder is reduced.

[0016] 2. The utility model sets a fixed frame in the chimney and rotates a rotating rod connected to the fixed frame. When the gas containing desulfurizer powder is introduced into the chimney, a high-speed airflow is formed. When the airflow passes through the fan blades, the fan blades and the rotating rod are rotated, which in turn drives the support rod and the mixing plate to rotate. The desulfurizer powder and the flue gas are mixed by the rotating mixing plate, so that the desulfurizer powder is fully in contact with the sulfides in the flue gas, thereby increasing the desulfurization effect.

[0025] It should be noted that the feeding assembly 1 is used for storing and feeding the desulfurizer powder. The feeding assembly 1 is mainly composed of a silo 101 and a feeder 105. The silo 101 is a conical design and is used to store the desulfurizer powder. The feeder 105 is arranged at the bottom of the silo 101 and is mainly composed of a spiral feeding blade 1051 and a feeding pipe 1052. The feeding pipe 1052 is connected to the bottom of the silo 101. When the spiral feeding blade 1051 rotates, the desulfurizer powder can be fed. The spiral feeding blade 1051 is a conical design and is used to store the desulfurizer powder. The faster the rotation speed of 51, the faster the feeding speed, and vice versa, the slower it is, so as to control the discharge speed of the desulfurizer powder. By connecting the delivery pipe 3 at the lower end of the feeding pipe 1052, the desulfurizer powder can enter the air delivery mechanism 4, and the air delivery treatment of the desulfurizer powder is realized. The air delivery mechanism 4 is mainly composed of the air delivery pipe 401 and the Roots blower 402. When working, the Roots blower 402 can generate strong wind, and then blow the desulfurizer powder into the discharge pipe 6, to realize the feeding of the desulfurizer powder, and then carry out desulfurization treatment of the flue gas.

[0026] like Figure 2 As shown, in some embodiments, a mounting bracket 102 is fixedly connected to the inner upper portion of the silo 101, and a motor 103 is installed at the center of the mounting bracket 102. A shaft 104 is fixedly connected to the output shaft of the motor 103. The lower end of the shaft 104 is coaxially connected and fixed to the fixed rod at the center of the spiral feeding blade 1051, and the lower end of the fixed rod is rotatably connected to the support plate 1053 provided at the bottom of the feeding pipe 1052.

[0027] It should be noted that by setting a fixed rod at the center of the spiral feeding blade 1051, the spiral feeding blade 1051 can rotate stably. The mounting frame 102 is used to install the motor 103. When the motor 103 is working, it can drive the shaft 104 to rotate. The lower end of the shaft 104 is coaxially connected to the upper end of the fixed rod, thereby realizing the rotation drive of the spiral feeding blade 1051. The lower end of the fixed rod is rotatably connected to the support plate 1053 set at the bottom of the feeding tube 1052, thereby realizing the stable rotation of the spiral feeding blade 1051.

[0028] like Figure 1 and Figure 2 As shown, in some embodiments, a support frame 2 is fixedly connected to the outer wall of the silo 101 to achieve a supporting function for the silo 101 .

[0029] like Figure 3 As shown, in some embodiments, the air inlet port of the air delivery duct 401 is connected to an air collecting tube 403 , and a filter 404 is fixedly connected to the inner wall of the air collecting tube 403 .

[0030] It should be noted that the air collecting tube 403 is provided to protect the air inlet of the air delivery duct 401 , and a filter 404 is provided on the inner side of the air collecting tube 403 to prevent the entry of debris.

[0031] like Figure 1 and Figure 3 As shown, in some embodiments, a support base 5 is provided on the air delivery duct 401 to support the air delivery duct 401 .

[0032] like Figure 1 and Figure 4 As shown, in some embodiments, the end of the discharge pipe 6 is connected to the chimney 7, and a high-temperature resistant fixing frame 8 is fixedly connected to the inner wall of the chimney 7, a rotating rod 9 is rotatably connected to the center of the fixing frame 8, and the upper part of the rotating rod 9 is fixedly connected to an array of fan blades 10, and a plurality of support rods 12 are fixed to the bottom of the rotating rod 9, and a mixing plate 11 is fixedly connected to each of the support rods 12.

[0033] It should be noted that the gas containing desulfurizer powder enters the chimney 7 through the discharge pipe 6, thereby realizing the desulfurization treatment of the flue gas in the chimney 7. By setting a fixed frame 8 on the inner side of the chimney 7, when the gas containing desulfurizer powder enters the inner side of the chimney 7, the high-speed airflow contacts the fan blades 10, which can then cause the rotating rod 9 and the fan blades 10 to rotate, causing the mixing plate 11 and the support rod 12 to rotate, and the desulfurizer powder and the flue gas are stirred through the mixing plate 11, so that the desulfurizer powder is in full contact with the sulfide in the flue gas, thereby accelerating the desulfurization treatment of the flue gas.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
