Abstract

This invention discloses a dust removal pretreatment device for industrial waste gas, relating to the field of industrial waste gas dust removal technology. The invention includes a base, with an air intake component mounted on top of the base, and a spray component located on one side of the air intake component. The invention employs a dual spray structure combining oscillating spraying from the air intake component and rotating three-dimensional spraying from the spray component. The arc-shaped pipe of the air intake component can oscillate back and forth to expand the initial contact range between the waste gas and the dust removal liquid. The double-layered annular pipes of different diameters in the spray component, combined with rotating atomizing nozzles, form a fully covered three-dimensional spray space. Combined with secondary filtration by the filter plates within the tower, this significantly increases the contact area and contact time between the industrial waste gas and the dust removal liquid, efficiently adsorbing large dust particles from the settled waste gas, improving the purification effect of dust in the waste gas, and achieving high-quality preliminary dust removal pretreatment of industrial waste gas, laying a solid foundation for subsequent fine dust removal.

Description

Technical Field

[0001] This invention belongs to the field of industrial waste gas dust removal technology, and in particular relates to a dust removal pretreatment device for industrial waste gas. Background Technology

[0002] Industrial waste gas is a general term for various gaseous pollutants generated and emitted into the atmosphere during industrial production processes. It is one of the main sources of air pollution and is widely generated in almost all industrial production fields such as metallurgy, chemical industry, power, building materials, machining, coating, and printing. Its composition, concentration, and emission volume are closely related to production processes, raw materials, and equipment levels. If it is emitted directly without effective treatment, it will cause serious harm to the atmospheric environment, ecosystems, and human health.

[0003] In the field of dust removal pretreatment for industrial waste gas treatment, traditional spray dust removal devices mostly adopt a spray structure with fixed nozzles. The spray angle and range of the nozzles are fixed. After the industrial waste gas enters the spray tower, it can only come into contact with the dust removal liquid in a local area. The contact area between the waste gas and the dust removal liquid is small and the contact time is short, which can easily lead to problems such as waste gas short circuit and spray dead corners, thereby reducing the dust removal effect.

[0015] The present invention has the following beneficial effects: 1. The present invention adopts a dual spray structure that combines the swing spray of the air inlet component with the rotating three-dimensional spray of the spray component. The arc-shaped pipe of the air inlet component can swing back and forth to expand the initial contact range between the exhaust gas and the dust removal liquid. The double-layer annular pipes of different diameters of the spray component, together with the rotating atomizing nozzle, form a fully covered three-dimensional spray space. In addition, the secondary filtration of the filter plate in the tower body greatly improves the contact area and contact time between the industrial exhaust gas and the dust removal liquid. It can efficiently adsorb large particulate dust in the settled exhaust gas, improve the purification effect of dust in the exhaust gas, and achieve high-quality preliminary dust removal pretreatment of industrial exhaust gas, laying a good foundation for subsequent fine dust removal.

[0016] 2. This invention employs a two-stage dust removal structure consisting of spray pretreatment and high-voltage electrostatic precipitator. After the spray assembly removes large dust particles, the guiding assembly evenly disperses the exhaust gas into the high-voltage electrostatic precipitator. The high-voltage electrostatic field formed by the cathode rod and anode plate charges and adsorbs the fine dust particles in the exhaust gas, achieving graded treatment of dust particles of different sizes. This solves the problem that a single dust removal method cannot effectively handle both large and small dust particles, significantly improving the overall dust removal effect and making the pretreatment of industrial exhaust gas more thorough, thus meeting the high standards required for industrial exhaust gas treatment.

[0017] 3. This invention employs a single-motor-based power supply structure, which simultaneously provides power for the intake and transport of industrial waste gas, the oscillation of the air intake components of the spray assembly, and the rotation of the spray components. Through transmission structures such as sprockets, chains, bevel gears, and worm gears, the power is rationally distributed and transmitted, effectively reducing the number of power sources required, simplifying the overall structure of the device, and significantly reducing energy consumption and subsequent maintenance costs. At the same time, the compatible use of various transmission structures ensures the stability and efficiency of power transmission, ensuring the continuous and smooth operation of each stage of waste gas treatment.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figure 1-15The present invention provides the following technical solution: a dust removal pretreatment device for industrial waste gas, comprising a base 1, an air intake component 2 disposed on the top of the base 1, a spray component 3 disposed on one side of the air intake component 2 disposed on the top of the base 1, a first transmission component 6 disposed on the rear side of the air intake component 2 disposed on the top of the base 1, a second transmission component 7 disposed on the top of the base 1 perpendicular to the transmission component and disposed on one side of the spray component 3, a high-voltage electrostatic dust removal component 8 disposed on the top of the base 1 disposed on one side of the spray component 3, and a flow guiding component 9 disposed on the top of the base 1 between the spray component 3 and the high-voltage electrostatic dust removal component 8; the air intake component 2 provides power for introducing industrial waste gas into the spray component 3 and the high-voltage electrostatic dust removal component 8; the spray component 3 is used for preliminary dust removal pretreatment of industrial waste gas; the first transmission component 6 and the second transmission component 7 are used in conjunction to provide power for the operation of the spray component 3; the high-voltage electrostatic dust removal component 8 treats fine dust in the waste gas, thereby improving the waste gas treatment effect.

[0023] The suction assembly 2 includes a first mounting plate 201 fixedly connected to the top of the base 1. A first pad 202 is fixedly connected to the top of the first mounting plate 201. A motor 203 is fixedly connected to the top of the first pad 202. A first rotating shaft 204 is fixedly connected to the output end of the motor 203. A first sprocket 205 is fixedly connected to the outer wall of the first rotating shaft 204. A second pad 206 is fixedly connected to the top of the first mounting plate 201. A fan duct 207 is fixedly connected to the top of the second pad 206. A second rotating shaft 208 is rotatably connected through one outer side of the fan duct 207. A rotating roller 209 located inside the fan duct 207 is fixedly connected to the outer wall of the second rotating shaft 208. A number of fan blades 210 are uniformly fixedly connected to the outer wall of the rotating roller 209. A second sprocket 211 is fixedly connected to one end of the second rotating shaft 208. A first chain meshes and drives the second sprocket 211 and the first sprocket 205. An air intake pipe 212 is connected to the opposite outer side of the air duct 207. A first exhaust pipe 213 is connected to the outer wall of the air duct 207. The air intake assembly 2 also includes a first support plate 214 fixedly connected to the top of the base 1.

A first bevel gear 216 is fixedly connected to the output end of the reducer 215.

[0024] The operation process of this embodiment is as follows: First, the industrial waste gas pipeline is connected to the intake pipe 212. After the motor 203 is started, it drives the first rotating shaft 204 to rotate. On the one hand, the first rotating shaft 204 drives the second rotating shaft 208 to rotate synchronously through the meshing transmission of the first sprocket 205, the first chain and the second sprocket 211. This causes the rotating roller 209 and the fan blade 210 inside the air duct 207 to rotate, forming a negative pressure suction force to draw the industrial waste gas from the intake pipe 212 into the air duct 207, and then transport it to the spray assembly 3 through the first exhaust pipe 213, providing stable conveying power for the subsequent treatment of the waste gas. The transmission method of this sprocket and chain is as follows: With high dynamic efficiency and strong stability, it can ensure the continuity of exhaust gas intake and transportation. On the other hand, the first rotating shaft 204 transmits power to the reducer 215. After the speed is adjusted by the reducer 215, it drives the first bevel gear 216 to rotate, providing a suitable power input for the first transmission component 6. The reducer 215 can be set to adjust the speed of power output according to the actual working conditions, so that the working rhythm of the subsequent transmission component matches the exhaust gas treatment process. This realizes the effect of a single motor 203 simultaneously powering exhaust gas transportation and transmission components, effectively simplifying the power structure of the device, reducing the number of power sources, and reducing the energy consumption and maintenance costs of the device.

The outer wall of the arc-shaped pipe 404 is uniformly connected to a number of first atomizing nozzles 405. The outer wall of the first horizontal pipe 402 is symmetrically fixedly connected to a hinge seat 406. A connecting plate 407 is connected between the hinge seat 406 and the corresponding arc-shaped pipe 404. The outer walls of the two arc-shaped pipes 404 are fixedly connected to symmetrically arranged support rods 408. The two support rods 408 are fixedly connected to a first horizontal plate 409. One side of the first horizontal plate 409 is fixedly connected to a square rod 410 that is slidably connected to the tower body 302. The air intake component 4 also includes a first L-shaped plate 411 fixedly connected to the outer wall of the tower body 302. The end of the first L-shaped plate 411 is fixedly connected to a square pipe 412 that is slidably sleeved on the square rod 410. One end of the square rod 410 is hinged to a swing rod 413.

[0026] The inner wall of the tower body 302 is provided with a spray element 5 located above the air inlet 4. The spray element 5 includes a second mounting plate 501 fixedly connected to the inner wall of the tower body 302. A cylindrical tube 502 is rotatably connected through the top of the second mounting plate 501. The cylindrical tube 502 is connected to the first water pipe 304 by a bearing. The outer wall of the cylindrical tube 502 has two parallel second annular grooves 503. The inner wall of the second annular grooves 503 has several second notches 504 evenly distributed through it. The inner walls of the two second annular grooves 503 are rotatably connected to annular plates 505. Several first extension rods 506 are evenly fixedly connected to the outer wall of the annular plates 505. Annular tubes 507 are fixedly connected between the several first extension rods 506. Several annular sleeves 507 are evenly fixedly connected to the outer wall of the annular tubes 507, which are staggered with the first extension rods 506. 08. A second extension rod 509 is fixedly connected to the outer wall of the annular sleeve 508. A gear ring 510 that rotatably engages with the corresponding first annular groove 306 is fixedly connected between several second extension rods 509. Several downwardly oriented second atomizing nozzles 511 are uniformly connected to the outer wall of the annular tube 507. The diameter of the upper annular tube 507 is smaller than that of the lower annular tube 507. The spray component 5 also includes two second horizontal plates 512 fixedly connected to the outer wall of the tower body 302. A third rotating shaft 513 is rotatably connected to both sides of the two second horizontal plates 512. A first spur gear 514 that meshes with the corresponding gear ring 510 is fixedly connected to the outer wall of the third rotating shaft 513. The first spur gear 514 slides with the first notch 307. A driven bevel gear 515 is fixedly connected to both ends of the third rotating shaft 513.

[0027] The operation process of this embodiment is as follows: After the pump body 303 in the tower base 301 is started, the dust removal liquid is transported to the spray component 5 in the tower body 302 through the first water pipe 304. The industrial waste gas transported by the suction component 2 enters the first horizontal pipe 402 of the air intake component 4 through the first air intake pipe 401, and then is transported to the arc-shaped pipe 404 through the corrugated pipe 403 and sprayed out by the first atomizing nozzle 405, making initial contact with the dust removal liquid. At the same time, the swing rod 413 is driven by external force to slide the square rod 410 back and forth in the square pipe 412. The arc-shaped pipe 404 is driven to swing with the hinge seat 406 as the fulcrum through the first horizontal plate 409 and the support rod 408. The corrugated pipe 403 adapts to the swing of the arc-shaped pipe 404 to achieve flexible connection, effectively expanding the contact range between the waste gas and the dust removal liquid and improving the dust removal effect of the initial contact. After the dust removal liquid transported by the pump body 303 enters the cylindrical tube 502, it flows into the annular plate 505 and the annular tube 507 through the second notch 504 of the second annular groove 503. Finally, it is sprayed downwards by the second atomizing nozzle 511 to form a spray layer. When the third rotating shaft 513 is rotated by external force, the first spur gear 514 will mesh with the gear ring 510 to drive the annular tube 507 to rotate around the cylindrical tube 502. The annular tubes 507 with different upper and lower diameters, together with the rotating second atomizing nozzle 511, can form a three-dimensional and fully covered spray space, allowing the exhaust gas and dust removal liquid to fully contact and collide within the tower body 302, so that the exhaust gas contains dust removal liquid. Large dust particles are effectively adsorbed and settled, while the filter plate 305 inside the tower body 302 can also perform secondary filtration on the exhaust gas after spraying, further intercepting dust. The first annular groove 306 and the first notch 307 provide suitable motion space for the rotation of the gear ring 510 and the first spur gear 514, ensuring the smooth rotation of the spray component 5. The entire spray assembly 3, through the combination of the swing spray of the air inlet component 4 and the rotational three-dimensional spray of the spray component 5, greatly improves the contact area and contact time between the exhaust gas and the dust removal liquid, realizing efficient preliminary dust removal pretreatment of industrial exhaust gas, laying a good foundation for subsequent fine dust removal.

[0028] Example 3, please refer to Figure 1-15 This third embodiment improves upon the first embodiment as follows: The first transmission assembly 6 includes two first upright plates 601 fixedly connected to the top of the base 1. A worm gear 602 is rotatably connected between the two first upright plates 601. A second bevel gear 603 is fixedly connected to one end of the worm gear 602, and the second bevel gear 603 meshes with the first bevel gear 216. A third sprocket 604 is fixedly connected to the other end of the worm gear 602. The first transmission assembly 6 also includes a second upright plate 605 fixedly connected to the top of the base 1. A first rotating rod 606 is rotatably connected to one side of the second upright plate 605. A worm wheel 607 meshes with the worm gear 602 at one end of the first rotating rod 606. A turntable 608 is fixedly connected to the other end of the first rotating rod 606. A connecting post 609 is fixedly connected to one side of the turntable 608 at an offset point from the center. The connecting post 609 rotatably engages with the swing rod 413.

[0029] The second transmission assembly 7 includes a second L-shaped plate 701 fixedly connected to the top of the base 1. A second rotating rod 702 is rotatably connected through one side of the second L-shaped plate 701. A power bevel gear 703 that meshes with two driven bevel gears 515 is fixedly connected to one end of the second rotating rod 702. A fourth sprocket 704 is fixedly connected to the other end of the second rotating rod 702. A second chain meshes with the third sprocket 604.

[0030] The operation process of this embodiment is as follows: After the first bevel gear 216 of the intake component 2 rotates, it meshes with the second bevel gear 603 to drive the worm gear 602 to rotate between the two first vertical plates 601. The worm gear 602 meshes with the worm wheel 607 to drive the first rotating rod 606 to rotate on the second vertical plate 605, thereby causing the turntable 608 to rotate synchronously. The eccentrically arranged connecting column 609 on the turntable 608 then performs a circular motion and drives the swing arm 413 to swing back and forth, providing power for the reciprocating swing spray of the arc-shaped pipe 404 in the intake component 4. The transmission method of the worm gear 602 and the worm wheel 607 has self-locking property, which can effectively prevent the swing arm 413 from driving the transmission components in the opposite direction, improving the stability and accuracy of the transmission; on the other hand... When the worm gear 602 rotates, it drives the third sprocket 604 at its end to rotate. Through the meshing transmission of the second chain and the fourth sprocket 704, it drives the second rotating rod 702 to rotate on the second L-shaped plate 701. The power bevel gear 703 at the end of the second rotating rod 702 then meshes with the two driven bevel gears 515, synchronously driving the two sets of third rotating shafts 513 of the spray component 5 to rotate, providing power for the rotating three-dimensional spraying of the annular pipe 507 of the spray component 5. The meshing transmission of the sprocket and chain can ensure the high efficiency and synchronicity of power transmission, realizing the effect of a single power source simultaneously driving the air intake component 4 to swing and the spray component 5 to rotate. This effectively simplifies the transmission structure of the device, reduces the setting of power components, and reduces the energy consumption and maintenance difficulty of the device.

[0031] Example 4, please refer to Figure 1-15 This fourth embodiment is an improvement on the first embodiment, with the following improvements: The high-voltage electrostatic dust removal assembly 8 includes a dust collection box 801 fixedly connected to the top of the base 1. A plurality of cathode rods 802 are uniformly fixedly connected to the bottom of the dust collection box 801. A plurality of anode plates 803, adapted to the cathode rods 802, are uniformly fixedly connected to the bottom of the dust collection box 801. The cathode rods 802 and anode plates 803 are connected to an external power supply. A second exhaust pipe 804 is fixedly connected through one outer side of the dust collection box 801. The diversion assembly 9 includes a shaped pipe 9 that penetrates and connects to the top of the tower body 302. 01. The diversion assembly 9 also includes two fixed plates 902 fixedly connected to the top of the base 1. A second horizontal pipe 903 connected to the irregular tube 901 is fixedly connected between the two fixed plates 902. Several branch pipes 904 are provided on the outer wall of the second horizontal pipe 903, which penetrate into the dust collection box 801. The several branch pipes 904 are arranged alternately with several cathode rods 802. A control box 10 is fixedly connected to the top of the base 1. A PLC controller is provided inside the control box 10. The PLC controller is electrically connected to the motor 203, the pump body 303 and the external power supply through wires.

[0032] The operation process of this embodiment is as follows: After the exhaust gas is initially dusted by the spray assembly 3, it enters the second horizontal pipe 903 of the diversion assembly 9 through the irregular pipe 901 at the top of the tower body 302. Then, it is evenly fed into the dust collection box 801 by several branch pipes 904 that are staggered with the cathode rod 802. The staggered layout of the branch pipes 904 and the cathode rod 802 can make the exhaust gas evenly dispersed in the dust collection box 801, avoid local exhaust gas accumulation, and ensure that each part of the exhaust gas can fully pass through the electrostatic dust removal area, thereby improving the dust removal efficiency. After the cathode rod 802 and the anode plate 803 in the dust collection box 801 are connected to an external power source, a high-voltage electrostatic field is formed. When the fine dust particles in the exhaust gas pass through this electric field, they will be charged and then adsorbed onto the anode plate 803 under the action of the electric field force, thus realizing the removal of fine dust that the spray assembly 3 cannot handle. The system efficiently captures and pre-treats the exhaust gas with deep dust removal. The treated clean exhaust gas is finally discharged through the second exhaust pipe 804. The control box 10 on the base 1 has a built-in PLC controller, which is electrically connected to the motor 203, pump body 303 and external power supply. It can realize centralized intelligent control of each power component and electrostatic dust removal module. It can accurately adjust the speed of motor 203, the liquid supply of pump body 303 and electrostatic field voltage according to the actual working conditions of exhaust gas treatment, so that the working rhythm of each component of the device is highly matched, which not only ensures the dust removal effect, but also avoids energy waste. At the same time, the centralized control method also reduces the operation difficulty of the device and improves the automation and intelligence level of the overall operation. The fixed structure of each component ensures the stability of the equipment during operation, making the fine dust removal process efficient and reliable.
