Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to an electric dust removal device. Background Art

[0002] An electrostatic precipitator (ESP) is a device that uses an electric field to remove particulate matter from the air. It generates an electrostatic field, charging the airborne particles. The electric field then draws the charged particles to a collecting electrode, separating the particles from the air and securing them to the collecting electrode. This device typically consists of an electric field module, a collecting electrode, a high-voltage power supply, and a control system. It is widely used in industrial production processes for dust control and pollutant management, effectively removing fine particulate matter from the air, improving the production environment and protecting employee health. Existing ESP devices, such as CN220589301U ("An ESP Device"), have a filter screen fixed within the filter barrel. After prolonged use, dust easily accumulates on the filter screen within the device. If not cleaned promptly, the ESP's operating efficiency can be reduced. Furthermore, the device uses a secondary vacuum pump and a secondary vacuum pipe to pump the initially filtered and purified air into a water tank. Large particles remaining in the dust can accumulate in the secondary vacuum pipe, resulting in poor purification results. Utility Model Content

[0023] The utility model is further described below.

[0024] The utility model provides an electric dust removal device, which is mainly used for air dust removal, including a box body 1, one end of the box body 1 is connected to an air inlet cylinder 11, and the other end of the box body 1 is connected to an air outlet cylinder 12, and a detachable sealing plate 13 is provided on the side of the box body 1, and a first purification mechanism 2 is provided in the box body 1, and the first purification mechanism 2 includes a frame frame 21 and an electrode sheet 22, the frame frame 21 is slidably arranged in the box body 1 along the width direction of the box body 1, the electrode sheet 22 is arranged on the top of the frame frame 21, and a filter plate 23 is detachably arranged in the frame frame 21, and a filter screen 231 is provided on the filter screen plate 23, and a plurality of the filter screen plates 23 are evenly spaced and arranged in the frame frame 21 along the length direction of the frame frame 21.

[0025] like Figure 1-Figure 7 As shown, the electric dust removal device includes a box body 1, and an air inlet tube 11 and an air outlet tube 12 are respectively provided at both ends of the box body 1, so that the gas at the construction site can be sucked into the electric dust removal device for dust removal and purification before being discharged; a detachable sealing plate 13 is provided on the side of the box body 1 to facilitate maintenance of the components in the box body 1. Specifically, the sealing plate 13 and the box body 1 can be connected by hinges, bolts or snap connections. A first purification mechanism 2 is provided in the box body 1, and the first purification mechanism 2 includes a frame 21 and an electrode sheet 22. The frame 21 is slidably arranged in the box body 1. Specifically, as shown in FIG. Figure 3 、 Figure 4As shown, two second slide grooves 16 arranged along the width direction of the box body 1 are opened at the bottom of the box body 1, and a slider 26 adapted to the second slide groove 16 is set at the bottom of the frame frame 21, so that the frame frame 21 can slide along the width direction of the box body 1, so that the subsequent operator can easily take the frame frame 21 out of the box body 1, and the sliding direction of the frame frame 21 is designed to slide along the width direction of the box body 1, so that the filter plate 23 subsequently installed in the frame frame 21 is always parallel to the vertical plane where the air intake cylinder 11 is located, so that the air input from the air intake cylinder 11 can pass through multiple filter plates 23 in sequence, and the filter plates 23 are used to adsorb and remove impurities in the air; the electrode sheet 22 is set on the top of the frame frame 21, and the filter plate 23 is used to remove dust from the filter plate 23. The interior of the frame 21 is detachably provided with a plurality of filter plates 23. Specifically, the detachable connection between the filter plate 23 and the frame 21 can be achieved by plugging in from top to bottom or slidingly connecting with a pulley groove. By arranging a filter screen 231 on the filter plate 23, it is ensured that the filter screen 231 can always be kept vertically arranged in the frame 21, and will not be deformed during use, effectively intercepting solid particles in the air to ensure the air purification effect; when in use, the electrode sheet 22 is energized, and the air inlet cylinder 11 and the air outlet cylinder 12 are opened. At this time, the external air is input into the box body 1 from the air inlet cylinder 11, and the electrode sheet 22 generates an electrostatic force field, which charges the particles in the air, and uses the electric field force to attract the charged particles to the electrode sheet. 22, thereby separating the particles from the air and fixing them on the collecting electrode sheet 22, and the air is filtered and purified for the second time through the filter plate 23 in the box body 1, further screening out the solid particles carried in the air, improving the dust removal efficiency and ensuring the dust removal effect.

The frame 21 with the electrode sheet 22 and the filter plate 23 ensures the continuous use of the electric dust removal device and improves the dust removal efficiency. By sliding the frame 21 to the box body 1, it is convenient to slide the frame 21 as a whole into and out of the box body 1 to clean the electrode sheet 22 at its top. The filter plate 23 detachably connected to the frame 21 is convenient for the operator to disassemble the filter plate 23 and clean the filter plate 23 to ensure that the surfaces of the filter plate 23 and the electrode sheet 22 are always clean, so as to adsorb large particles in the air, ensure the dust removal effect, improve the dust removal efficiency, and avoid long-term accumulation of dust on the surface of the filter plate 23 and the electrode sheet 22, which affects their adsorption effect on impurities in the air and reduces the working efficiency of the device.Furthermore, the installation spacing and number of filter plates 23 can be designed according to the actual use scenario of the electric precipitator, so as to design for different use scenarios and reduce manufacturing costs.

[0026] It is convenient to remove the filter plate 23 as a whole and clean the filter plate 23, saving the time of removing the filter plates 23 one by one.

Figure 3 As shown, the frame 21 has an opening on one side close to the air inlet duct, so that the connecting rod 24 can slide into the longitudinal rod 212 along the first slide groove 2121, making it convenient for the connecting rod 24 to slide in and out of the first slide groove 2121. At the same time, the opening is set on the side close to the air inlet duct, which can ensure that the filter plate 23 is always installed along the length direction of the box body 1, so as to remove dust from the air entering from the air inlet duct, and can ensure the installation stability of the filter plate 23. The filter plate 23 is then set on the connecting rod 24, and the filter plate 23 installed on the connecting rod 24 can be driven to slide into the frame 21 or out of the frame 21 as a whole by sliding the connecting rod 24. The filter plate 23 set in the frame 21 can be removed as a whole, and the filter plate 23 can be cleaned, saving the time of disassembling the filter plates 23 one by one.

[0027] To ensure that the connecting rod 24 in the frame 21 will not slip off the frame 21 during use of the electric precipitator, Figure 4 、 Figure 5 As shown, two grooves 2131 are provided along the length direction of the vertical rod 213 on the side of the vertical rod 213 close to the air intake cylinder 11, and a circular groove 2132 is provided on the side of the groove 2131 facing away from the air intake cylinder 11, which is connected to the first sliding groove 2121. A first spring 2133 and a limiting rod 2134 are sequentially provided in the circular groove 2132, and the limiting rod 2134 is slidably provided in the circular groove 2132. A push piece 2135 perpendicular to the limiting rod 2134 is provided between the first spring 2133 and the limiting rod 2134, and the push piece 2135 is movably provided in the groove 2131. The length of the groove 2131 is less than the length of the first spring 2133; as shown Figure 3As shown, two grooves 2131 are provided along the length direction of the vertical rod 213, and a circular groove 2132 connected to the first slide groove 2121 is provided on the side of the groove 2131 facing away from the air intake cylinder 11, and a limit rod 2134 is slidably set in the circular groove 2132, one end of the limit rod 2134 is connected to the first slide groove 2121, and the other end is connected to the first spring 2133, and the limit rod 2134 is driven to slide up and down in the circular groove 2132 by a push piece 2135 vertically connected to the limit rod 2134, to control the positional relationship between the limit rod 2134 and the first slide groove 2121, that is, whether the limit rod 2134 is in contact with the first slide groove 2121, and the elasticity of the first spring 2133 is used to ensure that the limit rod 2134 is always in contact with the first slide groove 2121 and will not slip off.

[0028] In order to adjust the number and spacing of the filter plates 23 according to different places of use and air quality, Figure 4 As shown, a fixing frame 25 is fixed to the connecting rod 24, and a plurality of the fixing frames 25 are evenly spaced along the length direction of the connecting rod 24. The filter plate 23 can be detachably installed in the fixing frame 25; specifically, the filter plate 23 can be detachably installed in the fixing frame 25 by means of snap connection, mortise and tenon connection, bolt connection, or latch connection. By fixing the fixing frames 25 evenly spaced along the length direction of the connecting rod 24 on the connecting rod 24, and by installing the filter plates 23 in different fixing frames 25, the number and spacing of the filter plates 23 can be adjusted to adapt to different construction environments, to remove dust from air polluted to different degrees, to improve the dust removal efficiency, and to ensure the dust removal effect. As a preferred method, in order to facilitate the rapid installation of the filter plate 23 in the fixing frame 25, as shown in FIG. Figure 5The bottom of the filter plate 23 is provided with a latch hole 232, and the bottom of the fixing frame 25 is provided with a limiting hole 251 corresponding to the latch hole 232. A latch rod 233 is provided in the latch hole 232, and a limiting plate 235 is provided at one end of the latch rod 233 near the limiting hole 251. A second spring 234 is sleeved on the latch rod 233, and one end of the second spring 234 is connected to the limiting plate 235, and the other end is connected to the latch hole 232. A limiting block 236 is provided on the other side of the limiting plate 235 that is adapted to the limiting hole 251. The diameter of the limiting plate 235 is larger than the diameter of the limiting block 236. When in use, the latch rod 233 is pulled upward, and the limiting plate 235 squeezes the second spring 234 to drive the limiting block 236 to move upward. When the filter plate 23 is stuck in the fixing frame 25 When the filter plate 23 is in the closed position, the second spring 234 is released to move the limit block 236 downwards and into the limit hole 251, thereby achieving the connection between the filter plate 23 and the fixing frame 25. The filter plate 23 is always connected to the fixing frame 25 during use by the second spring 234 and will not fall off. When it needs to be disassembled, the latch rod 233 is lifted up, and the limit plate 235 squeezes the second spring 234 to drive the limit block 236 to move upwards until the limit block 236 is completely out of the limit hole 251, and the filter plate 23 can be removed from the fixing frame 25. In this way, the filter plate 23 can be disassembled and cleaned by pulling the latch rod 233, thereby avoiding long-term accumulation of dust on the surface, which leads to reduced dust removal efficiency of the electric dust removal device.

[0029] In order to further purify the gas after the first purification mechanism 2, effectively remove the particulate matter in the exhaust gas and purify the air, Figure 3 、 Figure 7As shown, the electric dust removal device also includes a second purification mechanism 3 arranged in the box body 1 near one end of the air outlet 12, a partition plate 17 is provided between the first purification mechanism 2 and the second purification mechanism 3, and an air suction fan 171 is provided on the partition plate 17. The second purification mechanism 3 includes a water spraying mechanism 31 and a liquid collecting hopper 32. The water spraying mechanism 31 includes a water inlet pipe 311 arranged through the top of the box body 1, and the water outlet end of the water inlet pipe 311 is connected to a diverter pipe 312.

The liquid collecting hopper 32 The water spray mechanism 31 and the first purification mechanism 2 are arranged in the same box 1, so as to avoid the use of an air duct to guide the gas treated by the first purification mechanism 2, and to avoid the accumulation of some large particles in the gas in the air duct, thereby affecting the purification effect; the second purification mechanism 3 is separated from the first purification mechanism 2 by setting a partition plate 17, so as to avoid the water mist of the second purification mechanism 3 from entering the first purification mechanism 2 and affecting the normal use of the first purification mechanism 2. 17 is provided with a suction fan, which sucks the air processed by the first purification mechanism 2 into the second purification mechanism 3 for further treatment. By setting the second purification mechanism 3, the water inlet pipe 311 is connected to the external water source, and then the diversion pipe 312 and the atomizing nozzle 313 are used to spray the water flow into the box body 1 in the form of mist, so as to purify the air processed by the first purification mechanism 2 again, and finally discharge the purified air through the air outlet 12; by spraying water mist, the particles in the air are wrapped with water mist, and due to the moistening and weight-increasing effect of water, the particles in the air are more easily It is easy to settle under the action of gravity, and can effectively remove particulate matter such as smoke, cement dust, coal dust, etc. in the construction site and purify the air; in order to avoid water accumulation in the box body 1, a liquid collecting bucket 32 is detachably connected to the bottom of the box body 1, and the liquid is drained by opening a through hole connected to the liquid collecting bucket 32 at the bottom of the box body 1.

The fibers or yarns are arranged in a certain organizational structure and are a porous aggregate, which can capture dust in the dust-laden airflow. As the filtration proceeds, part of the dust is retained on the surface of the cellulose layer 34 to form a dust layer, and part of the fine dust penetrates into the interior of the fiber layer. The formation of the dust layer can significantly improve the filtration efficiency, and due to the characteristics of the pore structure in the cellulose layer 34, the accumulated dust is easy to loosen and disperse, making it easy to remove.
