Description

Technical Field

[0001] This utility model relates to the field of flue gas desulfurization technology, and in particular to a dry flue gas desulfurization device. Background Technology

[0002] Coal-fired flue gas contains a large amount of dust and SO2. Untreated coal-fired flue gas emitted into the atmosphere pollutes the atmospheric environment. Dry flue gas desulfurization involves reacting CaO with SO2 in the flue gas to produce calcium sulfate, or using electron beam irradiation or activated carbon adsorption to convert SO2 into ammonium sulfate or sulfuric acid. However, existing dry desulfurization devices cannot detect the sulfur concentration in the flue gas during use, making it impossible to determine whether emission standards are met, resulting in poor practicality. To meet market needs, a new dry flue gas desulfurization device is required.

[0003] A search revealed a Chinese patent with authorization number 201820257876.8, which discloses a dry flue gas desulfurization device, including a flue gas cylinder, a desulfurizing agent cylinder installed above the flue gas cylinder, a desulfurizing agent unloading hopper with vent holes installed below the desulfurizing agent cylinder, and the discharge port of the desulfurizing agent unloading hopper extending out of the flue gas cylinder. The aforementioned dry flue gas desulfurization device in the patent has the following shortcomings: The sealing and leak-proof performance of existing dry desulfurization devices needs further improvement, which makes it easy for flue gas to leak between the assembly pipe and the inlet pipe when entering the desulfurization chamber, potentially causing adverse effects on the surrounding environment. Furthermore, existing dry desulfurization devices typically lack the function of preventing calcium oxide agglomeration, which means the uniformity of the calcium oxide powder cannot be ensured, reducing the reaction efficiency between the calcium oxide powder and sulfur dioxide in the flue gas. In addition, the existing dry desulfurization devices are not convenient to install and remove the first filter screen, resulting in a long installation and removal time for operators and failing to guarantee the stability of the first filter screen during installation.

[0018] Reference Figure 2 and Figure 7 Furthermore, the assembly pipe 101 and the air intake pipe 125 are provided with a sealing and leak-proof mechanism 4. The sealing and leak-proof mechanism 4 consists of an annular silicone pad 44 provided on the inner wall of the assembly pipe 101, an annular rubber pad 43 provided on the surface of the annular silicone pad 44, a positioning block 41 provided on the surface of the annular rubber pad 43, and a sealing ring 42 provided on the inner wall of the air intake pipe 125. The annular silicone pad 44 is installed on the inner wall of the assembly pipe 101. The annular rubber pad 43 for sealing between the assembly pipe 101 and the air intake pipe 125 is installed on the surface of the annular silicone pad 44. Multiple sets of positioning blocks 41 are symmetrically installed on the surface of the annular rubber pad 43. The positioning blocks 41 are engaged with the inner wall of the air intake pipe 125. The sealing ring 42 is installed on the inner wall of the air intake pipe 125. The inner wall of the sealing ring 42 is in contact with the inner wall of the assembly pipe 101. By setting up a sealing and leak-proof mechanism, it is possible to prevent the flue gas from leaking between the assembly pipe 101 and the inlet pipe 125 when it enters the desulfurization box 1, thus avoiding adverse effects on the surrounding environment.

[0019] Specifically, in use, the dry flue gas desulfurization device is operated as follows: First, the desulfurization box 1 is placed in the designated location. The assembly pipe 101 is then assembled onto the surface of the inlet pipe 125 using bolts 126. Flue gas enters the desulfurization box 1 through the assembly pipe 101 and the inlet pipe 125. It first passes through the flow equalization plate 104, ensuring even distribution of the flue gas on the first filter plate 124. Subsequently, the flue gas passes through the first filter plate 124 and enters the desulfurization box 1. The calcium oxide, pulverized into powder, enters the material bin 12 through the feed pipe assembly 105 for storage. The controller 11 controls the discharge valve 123 on the surface of the conveying pipe 122. When the desulfurization chamber 1 is opened, the calcium oxide inside the feed hopper 12 enters the feed plate 119 through the feed pipe 122. The feed plate 119 evenly sprays the calcium oxide into the desulfurization chamber 1, allowing it to fully contact and react with the flue gas inside the desulfurization chamber 1. The acidic components such as sulfur dioxide in the flue gas react with the calcium oxide to generate solid particles such as calcium sulfite. Under the action of gravity, the solid particles fall onto the surface of the first filter screen plate 124. Some solid particles remain on the surface of the first filter screen plate 124, while some solid particles fall into the slag discharge pipe 102. The controller 11 controls the discharge valve 103 to open at regular intervals, and the bottom of the desulfurization chamber 1... Solid particles from the desulfurization chamber automatically fall through the slag discharge pipe 102 into an external transport vehicle for removal. Subsequently, the controller 11 opens the first valve 110 on the surface of the extraction pipe 109, allowing the desulfurized gas inside the desulfurization chamber 1 to enter the detection chamber 13 through the outlet pipe 108 and the extraction pipe 109. The sulfur dioxide detector 111 detects the sulfur concentration in the gas. If the concentration meets the standard, the sulfur dioxide detector 111 sends a signal to the controller 11. The controller 11 automatically analyzes the signal received from the sulfur dioxide detector 111 and controls the exhaust pipe 115. The second valve 114 on the surface opens, allowing gas to be discharged into the bag filter 14 for dust removal. If the sulfur concentration in the gas is found to be below standard, the sulfur dioxide detector 111 sends a signal to the controller 11. The controller 11 receives and analyzes the signal from the sulfur dioxide detector 111 and controls the air pump 117 to operate. Under the action of the air pump 117, the gas that fails to meet the emission standards is drawn out from the detection chamber 13 through the suction plate 116 and returned to the desulfurization chamber 1 through the ventilation pipe 118 for desulfurization treatment again until the sulfur concentration in the gas meets the emission requirements. The specific composition and working principle of the bag filter 14 are existing technologies and will not be described in detail here. The specific composition and working principle of the exhaust assembly 113 are also existing technologies and will not be described in detail here.

[0020] Subsequently, when the assembly tube 101 is installed on the surface of the intake pipe 125, the annular silicone pad 44 and the annular rubber pad 43 on the inner wall of the assembly tube 101 move to the inner wall of the intake pipe 125, and the surface of the annular rubber pad 43 moves to contact the inner wall of the intake pipe 125. At this time, the positioning block 41 on the surface of the annular rubber pad 43 engages with the inner wall of the intake pipe 125, and the sealing ring 42 on the inner wall of the intake pipe 125 moves to fit tightly against the inner wall of the assembly tube 101. The combined action of the rubber gasket 43 and the annular silicone gasket 44 provides a good seal between the assembly pipe 101 and the inlet pipe 125, preventing the flue gas from leaking between them. This achieves the function of sealing and preventing leakage of the desulfurization device, thus avoiding the leakage of flue gas between the assembly pipe 101 and the inlet pipe 125 when the desulfurization device is in use, and preventing adverse effects on the surrounding environment.

[0021] Subsequently, after the powdered calcium oxide enters the inside of the hopper 12, in order to further ensure the treatment effect of calcium oxide on flue gas, it is necessary to ensure the uniformity of calcium oxide powder particles. The controller 11 controls the drive motor 22 to work, and the drive motor 22 drives the rotating shaft 24 to rotate. When the rotating shaft 24 rotates, the rotating shaft 24 drives the agitator 21 and the mixing rod 25 to rotate inside the hopper 12. Under the combined action of the mixing rod 25 and the crushing ball 26, the calcium oxide powder inside the hopper 12 is crushed and stirred again to avoid the phenomenon of calcium oxide powder agglomeration and unevenness. This avoids the reduction of the reaction effect on sulfur dioxide in flue gas due to uneven calcium oxide powder particles. At the same time, when the powdered calcium oxide enters the inside of the spreading plate 119 through the conveying pipe 122, it will not cause the conveying pipe 122 to be blocked, so as to achieve the function of uniform crushing of the desulfurization device. This ensures the uniformity of calcium oxide powder when the desulfurization device is used, and improves the reaction efficiency of calcium oxide powder with sulfur dioxide in flue gas.

[0022] Subsequently, when the solid particles generated by the reaction of flue gas and calcium oxide powder fall onto the surface of the first filter plate 124, if the surface of the first filter plate 124 is not cleaned for a long time, it will cause blockage, affecting the normal entry of flue gas. After the user pulls the baffle 120 and removes it from the surface of the desulfurization box 1, the user loosens the fastening studs 34 on the surface of the anti-loosening sleeve 33, so that the fastening studs 34 drive the pressing plate 32 away from the surface of the first filter plate 124. The user then pulls the first filter plate 124, so that the first filter plate 124 drives the guide block 31 and the slider 36 to slide on the inner wall of the desulfurization box 1 and the surface of the support base 35, respectively. Under the joint action of the guide block 31 and the slider 36, the first filter plate 124 is guided. At the same time, the installation position of the first filter plate 124 can be quickly aligned. The user then replaces the first filter plate 124. When the first filter plate 124 is placed inside the desulfurization box 1, the time required for its alignment and installation is reduced. The user pushes the first filter plate 124 until it is fully inside the desulfurization box 1, and then tightens the fastening studs 34 on the inner wall of the desulfurization box 1. This causes the fastening studs 34 to move the pressure plate 32 downwards. With the cooperation of the fastening studs 34 and the pressure plate 32, the first filter plate 124 is pressed and fixed onto the surface of the support base 35. The pressure plate 32 prevents the fastening studs 34 from accidentally loosening, ensuring the stability of the first filter plate 124 when installed inside the desulfurization box 1. This facilitates the disassembly and assembly of the discharge valve 123 of the desulfurization device, saving the operator time in disassembling and assembling the first filter plate 124 during use. At the same time, it ensures the stability of the first filter plate 124 during installation, ultimately completing the operation of the dry desulfurization device.
