[0002] Sintering flue gas desulfurization and dust removal refers to the desulfurization and dust removal of the flue gas generated during the sintering process to reduce the emission of pollutants such as sulfur dioxide and particulate matter in the flue gas.

[0003] Flue gas treatment equipment typically filters dust from the flue gas. After removing solid impurities, the flue gas is then directed into a desulfurization tower for desulfurization and discharged after treatment. Bag filters are the primary method for dust removal, as they can intercept very small impurities and provide excellent filtration. However, this can also lead to clogging of gaps in the bags, causing impurities to accumulate and form agglomerates, which can affect airflow and directly impact the filtration process.

[0004] Therefore, it is necessary to provide a new sintering flue gas desulfurization and dust removal device to solve the above technical problems. Utility Model Content

[0028] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0029] See also Figures 1 to 4 The embodiment of the present invention provides a sintering flue gas desulfurization and dust removal device, which includes a pipeline structure, and a filter element 8 is also installed in the pipeline structure;

[0030] The pipeline structure includes an air inlet pipe 1, one end of which is connected to a filter pipe 2, the other end of which is connected to a guide pipe 3, the outer wall of which is also connected to an air outlet pipe 4. The filter pipe 2 is vertically arranged, and the lower end of the filter pipe 2 is a discharge port, and a valve pipe 5 for controlling the opening and closing of the discharge port is also installed;

[0031] The filter element 8 is installed inside the filter tube 2 and includes a filter bag 83;

[0032] A diversion mechanism and a transmission vibrator 9 connected to the diversion mechanism are also installed inside the diversion pipe 3. The transmission vibrator 9 includes a striking head 97 that can move in the vertical direction. The striking head 97 can collide with the filter element 8 to cause the filter bag 83 to vibrate.

[0033] It should be noted that in this device, the air inlet pipe 1 is an air intake pipe for conveying the flue gas into the pipeline structure. At the same time, a flow guide mechanism is added to the pipeline structure to further increase the flow rate, thereby improving the filtration efficiency. The air outlet pipe 4 is connected to the desulfurization tower to convey the filtered flue gas to the inside of the desulfurization tower for desulfurization operation.

[0034] The filter element 8 is mainly composed of a filter bag 83, which is used to intercept impurities. The intercepted impurities are concentrated inside the filter tube 2. The valve tube 5 is subsequently opened to discharge the impurities.

[0035] During the operation of the diversion mechanism, the transmission vibrator 9 will be driven to move together, and the transmission vibrator 9 can collide with the filter element 8, thereby causing the entire filter element 8 to vibrate. During the vibration of the filter bag 83, the impurities attached thereto can be shaken off to avoid impurities agglomeration, so as to facilitate subsequent deep cleaning.

[0036] In the embodiments of the present invention, please refer to Figure 2 The flow guide mechanism includes a motor 6 installed at one end of the flow guide tube 3. The output end of the motor 6 is fixed with a transmission shaft that rotates concentrically inside the flow guide tube 3, and an impeller 7 is installed on the transmission shaft.

[0037] It should be noted that the motor 6 can directly drive the impeller 7 to rotate, thereby accelerating the flow of air.

[0038] In the embodiments of the present invention, please refer to Figure 3 The filter element 8 also includes an outer ring frame 81 fixed to the inner wall of the filter tube 2, a concentric inner ring frame 82 is provided inside the outer ring frame 81, and a filter bag 83 is installed on the inner ring frame 82. There is a gap between the outer ring frame 81 and the inner ring frame 82, and the gap is closed by a folded silicone sheet 84;

[0039] A positioning ring plate 85 is also fixed inside the outer ring frame 81. The positioning ring plate 85 is located below the inner ring frame 82 and does not contact the filter bag 83. A plurality of springs 86 distributed in an annular shape are fixed between the inner ring frame 82 and the positioning ring plate 85 to support the inner ring frame 82 and the filter bag 83.

[0040] It should be noted that: in the filter element 8, the inner ring frame 82 is installed on the positioning ring plate 85 through the spring 86 to realize the installation of the filter bag 83. At the same time, the setting of the spring 86 can make the inner ring frame 82 have a vertical floating amount, and during the rapid movement, the filter bag 83 can vibrate. The folded silicone sheet 84 can play a sealing role and can also cooperate with the movement of the inner ring frame 82.

[0041] In the embodiments of the present invention, please refer to Figure 4 The transmission vibration member 9 includes a crankshaft 91, one end of the crankshaft 91 is concentrically fixed to the impeller 7, and the other end is rotatably connected to the guide tube 3. A collar 92 is rotatably connected to the crankshaft 91, and a first transmission rod 93 is vertically fixed to the circumferential outer wall of the collar 92. The other end of the first transmission rod 93 is fixed to a connecting end seat 94;

[0042] A second transmission rod 95 extending into the interior of the filter tube 2 is vertically provided below the first transmission rod 93. A spherical connector 96 is fixed to the upper end of the second transmission rod 95. The spherical connector 96 is embedded in and movably connected to the lower end of the connecting end seat 94. A knocking head 97 is fixed to the lower end of the second transmission rod 95.

[0043] A positioning frame 98 is also fixed to the inner wall of the filter tube 2 , and the second transmission rod 95 passes through the positioning frame 98 and is slidably connected thereto.

[0044] It should be noted that when the impeller 7 rotates, it can drive the crankshaft 91 to rotate, and then drive the collar 92 and the first transmission rod 93 to move together, so that the first transmission rod 93 can produce a vertical displacement, and then mobilize the second transmission rod 95 to move together. The second transmission rod 95 is limited by the positioning frame 98, so it can reciprocate in the vertical direction. During the descent, it can contact and collide with the inner ring frame 82, causing the filter bag 83 to vibrate.

[0045] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0046] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
