Description

Technical Field

[0002] A filter-type flue gas dust removal and desulfurization device is a type of equipment that combines flue gas filtration and desulfurization functions. It is mainly used in facilities that generate harmful gases, such as industrial boilers, coal-fired power plants, and smelters. Its main function is to simultaneously remove dust particles and harmful gases (such as sulfur dioxide) from the flue gas, thereby reducing environmental pollution.

[0003] Utility model patent CN219002569U discloses a dust removal and desulfurization device. The key technical points are: it includes a filter tower and a desulfurization tower, connected by a connecting pipe; the filter tower has a filter screen inside; a rotating shaft is rotatably connected to the middle of the inner top wall of the desulfurization tower via a bearing; and multiple spray pipes are fixedly connected to the outer surface of the rotating shaft. This utility model can automatically clean particulate matter and dust from the filter screen, improving the dust removal effect of the filter tower. Simultaneously, the back-and-forth oscillation of the stirring blades and spray pipes ensures that the flue gas in the desulfurization tower fully contacts the treatment liquid, improving the desulfurization effect. This solves the problems of existing desulfurization towers where the nozzle position is fixed, the sprayed treatment liquid cannot fully contact the flue gas, resulting in poor desulfurization effect, and the filter screen surface in the filter tower retaining a large amount of particulate matter and dust, which weakens the dust removal effect if not treated.

[0004] Regarding the above-mentioned issues, the following technical defects exist: Filter-type flue gas dust removal and desulfurization equipment is a device that combines flue gas filtration and desulfurization functions. It is mainly used in facilities that generate harmful gases, such as industrial boilers, coal-fired power plants, and smelters. Its main function is to connect the equipment through the inlet pipe and place the exhaust pipe outdoors. The dust removal and desulfurization equipment can remove dust particles and harmful gases from the flue gas, thereby reducing environmental pollution. However, the exhaust pipe and exhaust port of existing dust removal and desulfurization equipment are not detachable. This causes the surface of the exhaust pipe to age when it is exposed to the outdoors for a long time. In severe cases, it can lead to damage to the exhaust pipe, affecting the gas emission efficiency of the dust removal and desulfurization equipment. Utility Model Content

This causes the surface of the exhaust pipe to age when it is exposed to the outdoors for a long time. In severe cases, the exhaust pipe may be damaged, affecting the emission effect of the dust removal and desulfurization equipment. At this time, the aged exhaust pipe can be disassembled and replaced by adjusting the mechanism.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 4 The present invention provides a filter-type flue gas dust removal and desulfurization device, comprising: a dust removal and desulfurization device 1, an air inlet pipe 5 installed at the air inlet of the dust removal and desulfurization device 1, an exhaust pipe 4 installed at the exhaust outlet of the dust removal and desulfurization device 1, an adjustment mechanism 2 provided on the arc surface of the exhaust pipe 4, and an auxiliary mechanism 3 provided on the arc surface of the exhaust pipe 4.

[0027] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The adjusting mechanism 2 includes an installation ring 201, the inner wall of which is fixedly connected to the arc surface of the exhaust pipe 4. A sealing gasket 202 is fixedly connected to the side of the installation ring 201 near the dust removal and desulfurization equipment 1. A positioning block 203 is fixedly connected to the side of the dust removal and desulfurization equipment 1 near the installation ring 201. Two fixing rods 204 are fixedly connected to one side of the positioning block 203. A connecting groove 205 is provided on the installation ring 201 corresponding to the positions of the two fixing rods 204. The two fixing rods 204 are slidably connected to the inner wall of the connecting groove 205. A support plate 206 is fixedly connected to the side of the dust removal and desulfurization equipment 1 near the installation ring 201. A motor 207 is fixedly connected to one side of the support plate 206. The output end of the motor 207 is fixedly connected to... A power rod 208 is connected, and an adjusting plate 209 is threadedly connected to the arc surface of the power rod 208. Two positioning arms 210 are fixedly connected to one side of the adjusting plate 209. A positioning groove 211 is opened at the position of the two positioning arms 210 corresponding to the two positioning arms 210. The two positioning arms 210 are slidably connected to the inner wall of the two positioning grooves 211 respectively. A limit rod 212 slides through the inner wall of the adjusting plate 209. One end of the arc surface of the limit rod 212 is fixedly connected to one side of the dust removal and desulfurization equipment 1. The filter-type flue dust removal and desulfurization equipment 1 is a device that combines flue gas filtration and desulfurization functions. It is mainly used in facilities that generate harmful gases, such as industrial boilers, coal-fired power plants, and smelters. Its main function is to connect the air inlet pipe 5 with the equipment. After connecting the equipment, the exhaust pipe 4 is placed outdoors. The dust removal and desulfurization equipment 1 can then remove dust particles and harmful gases from the flue gas, thereby reducing environmental pollution. However, the existing exhaust pipe 4 of the dust removal and desulfurization equipment 1 is not detachable from the exhaust port. This causes the surface of the exhaust pipe 4 to age when it is exposed to the outdoors for a long time, which can lead to damage and affect the emission efficiency of the dust removal and desulfurization equipment 1. In this case, the aging exhaust pipe 4 can be disassembled and replaced using the adjustment mechanism 2. Replacing the exhaust pipe 4 with a new one through the adjustment mechanism 2 can improve the performance of the exhaust pipe 4 and enhance the stability of the emission gas from the entire dust removal and desulfurization equipment 1. The side of the connecting groove 205... A guide rod 213 is fixedly connected to the wall. The guide rod 213 slides through the inner wall of the two fixed rods 204. When the fixed rods 204 slide in the connecting groove 205, the guide rod 213 installed on the connecting groove 205 can improve the stability of the sliding of the fixed rods 204 in the connecting groove 205. A contact pad 214 is fixedly connected to the side of the support plate 206 away from the motor 207. The cross-section of the contact pad 214 is rectangular. The contact pad 214 can prevent the adjusting plate 209 from contacting the side of the support plate 206. The contact pad 214 can protect the contact position of the two. The limit rod 212 is a steel rod. The steel limit rod 212 has strong stability and is less likely to deform after long-term use, resulting in better performance. In the embodiments of this utility model, please refer to Figure 4The auxiliary mechanism 3 includes a top plate 31, which is slidably connected to the arc surface of the exhaust pipe 4. Four support arms 32 are fixedly connected to the side of the top plate 31 away from the exhaust pipe 4. A common fixed plate 33 is fixedly connected to the side of the four support arms 32 away from the top plate 31. A cylinder 34 is provided on the side of the fixed plate 33 away from the support arms 32. The output end of the cylinder 34 is fixedly connected to one side of the fixed plate 33. A bottom plate 35 is fixedly connected to the side of the cylinder 34 away from the fixed plate 33. Connecting arms 36 are fixedly connected to both sides of the bottom plate 35. When it is necessary to support the exhaust pipe 4 to improve the stability of the contact between the exhaust pipe 4 and the exhaust port of the dust removal and desulfurization equipment 1, this effect can be achieved through the auxiliary mechanism 3. The auxiliary mechanism 3 can reduce the pressure at the connection between the two and improve the connection effect. The two support arms 32 are fixedly connected to the same connecting plate 37 on the side close to each other. The inner wall of the connecting plate 37 is rotatably connected to the handle 38. When the angle of the auxiliary mechanism 3 needs to be adjusted, the position of the auxiliary mechanism 3 can be adjusted by the handle 38 installed on the connecting plate 37, which can improve the speed and efficiency of adjusting the auxiliary mechanism 3. The side of the base plate 35 away from the cylinder 34 is fixedly connected to the auxiliary pad 39. The side of the auxiliary pad 39 away from the base plate 35 is provided with anti-slip texture. The auxiliary pad 39 can increase the friction between the base plate 35 and the ground, thereby improving the stability of the entire auxiliary mechanism 3 in contact with the ground. The working principle of the filter-type flue gas dust removal and desulfurization device provided by this utility model is as follows: When it is necessary to improve the stability of the exhaust gas emitted by the dust removal and desulfurization equipment 1 by replacing the exhaust pipe 4, the aged exhaust pipe 4 needs to be removed from the exhaust port of the dust removal and desulfurization equipment 1 first: Start the motor 207 installed on the support plate 206. The movement of the motor 207 will drive the power rod 208 to rotate through the output end. The rotation of the power rod 208 will drive the adjusting plate 209 to slide downward along the direction of the limit rod 212. The movement of the adjusting plate 209 will drive the two positioning arms 210 to slide out of the positioning groove 211 opened on the mounting ring 201. At this time, the fixing effect of the positioning arms 210 on the mounting ring 201 can be released. Then, the two fixing rods 204 installed on the positioning block 203 will slide out from the connecting groove 205 of the mounting ring 201. At this time, the aged exhaust pipe 4 can be removed from the dust removal and desulfurization equipment 1 together with the mounting ring 201. When a new exhaust pipe 4 needs to be installed, the inner wall of the connecting groove 205 on the mounting ring 201 of the new exhaust pipe 4 is connected to the surface of the two fixing rods 204. At this time, the exhaust pipe 4 can be temporarily fixed to one side of the exhaust port of the dust removal and desulfurization equipment 1. The sealing gasket 202 on the mounting ring 201 can improve the sealing effect between the exhaust pipe 4 and the exhaust port. At this time, the motor 207 can be started. The movement of the motor 207 will drive the adjustment plate 209 to move through the power rod 208. The movement of the adjustment plate 209 will drive the positioning arm 210 to slide along the direction of the limit rod 212. At this time, the exhaust pipe 4 can be fixed to one side of the dust removal and desulfurization equipment 1 by connecting the positioning arm 210 to the inner wall of the positioning groove 211.

[0028] When it is necessary to reduce the pressure between the exhaust port and the exhaust pipe 4 of the dust removal and desulfurization equipment 1 in order to improve the connection effect between the exhaust port and the exhaust pipe 4, the top plate 31 is adjusted to a suitable position at the lower end of the exhaust pipe 4. At this time, the cylinder 34 installed on the base plate 35 can be started. The movement of the cylinder 34 will drive the four support arms 32 to move through the output end. The movement of the four support arms 32 will drive the top plate 31 to be adjusted in the direction of the exhaust pipe 4. When the top plate 31 contacts the exhaust pipe 4, the top plate 31 can support the bottom of the exhaust pipe 4. The connecting arm 36 installed on the base plate 35 can improve the stability of the base plate 35 in contact with the ground.
