Description

Technical Field

[0001] The self-balancing intelligent vehicle-mounted dust removal equipment of this invention is suitable for purifying municipal air, mining tunnels, steel plants, desulfurization and denitrification furnaces and other dust-generating scenarios, and belongs to the field of industrial dust removal technology. Background Technology

[0002] To promote pollution and carbon reduction and facilitate green transformation, the Ministry of Ecology and Environment and other departments have launched the "Implementation Plan for Synergistic Efficiency Enhancement of Pollution and Carbon Reduction" to address environmental pollutants from fossil energy consumption, industrial processing, and transportation. While industrial processing and production have led to rapid economic growth, they have also resulted in the generation of large amounts of greenhouse gases and fine particulate matter. Achieving carbon peaking and carbon neutrality is one of my country's current key tasks. While reducing pollution and carbon, it is also crucial to actively prevent and control air pollution and strictly control PM2.5. 2.5 The emission of industrial dust pollutants has led to a surge in dust production, which not only has a detrimental impact on the ecological environment but also causes significant harm to human health. When combustible dust mixes with air, it can explode upon contact with an open flame. Prolonged exposure to high concentrations of dust can cause dust particles to accumulate in the lungs, eventually leading to pneumoconiosis, silicosis, and other lung diseases, severely impacting health. Statistics show that from 2005 to 2020, my country experienced 67 dust explosion accidents, resulting in 476 deaths and 671 injuries, causing not only serious casualties but also public panic. In 2020, a total of 17,064 new cases of occupational diseases were reported nationwide, including 14,408 cases of occupational pneumoconiosis and other respiratory diseases, of which 14,367 were occupational pneumoconiosis. Although the number of new pneumoconiosis cases has been declining year by year, approximately 14,000 people are diagnosed with pneumoconiosis annually. Therefore, dust control in industrial production processes is of paramount importance.

[0003] Currently, commonly used industrial dust removal methods include bag filters, cartridge filters, wet scrubbers, cyclone separators, and electrostatic precipitators. While these technologies are significant in practical applications, they also have some drawbacks. Bag filters are unsuitable for dust with high water absorption rates and easily clog the filter media; cartridge filters are poorly suited for high-concentration dust and are difficult to clean; wet scrubbers struggle to capture hydrophobic dust and are significantly affected by low-temperature environments; cyclone separators have high maintenance costs; and electrostatic precipitators are highly sensitive to the particles within the integrated chamber and are prone to damage. These traditional dust removal methods all suffer from large footprints, low automation levels, and are unsuitable for complex scenarios with limited space or difficult access for personnel. Therefore, there is an urgent need for an intelligent, compact, highly integrated dust removal device capable of handling various types of dust particles. Summary of the Invention

[0038] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the features and implementation methods of the present invention can be more easily understood by those skilled in the art.

[0039] like Figure 1 The present invention provides a self-balancing intelligent vehicle-mounted dust removal device, which mainly includes twelve parts: a load trolley 1; 2-guide rails and telescopic rods 2; a negative pressure ejector dust removal device 3; a laser positioning instrument 4; a monitoring probe 5; a precision liquid control device 6; a flow control system 7; a water tank 8; a water pump housing 9; an adhesive housing 10; a power supply housing 11; and a self-balancing device 12. As can be seen from the figure, the device has a high degree of integration and good confidentiality. The external metal shell can provide good protection, and the built-in self-balancing device can effectively cope with dust on various slopes, steep ground, or narrow environments.

[0040] The load trolley 1 is made of hollow aluminum alloy. Hinges are installed on the side of the load trolley 1, and a power module can be arranged inside to improve the trolley's range. A level sensor, a WIFI module, a PLC control module, and a GPS positioning device are installed at the bottom of the load trolley. The level sensor determines the balance of the load trolley by measuring changes in the vehicle's tilt angle and transmits the acquired tilt angle signal to the PLC control module. The built-in program adjusts the regulating tube and hollow tube of the self-balancing device to ensure the load trolley remains level at all times. The GPS positioning device obtains the real-time location of the trolley. The WIFI module can feed back the trolley's location information, as well as parameters such as battery power, water storage capacity, and adhesive content, to the working gimbal.

[0041] The load trolley 1 is equipped with a laser locator 4 and a monitoring probe 5 on its top. The infrared beam of the infrared emitting tube of the laser locator 4 is scattered by dust particles. The intensity of the scattered light is proportional to the dust concentration, so the intensity of the infrared beam received by the photosensitive tube will change, which is converted into an electrical signal and finally transmitted to the pan-tilt unit. In the absence of supervision, the infrared laser locates areas with high concentrations of dust, realizing automatic tracking dust removal. The monitoring probe 5 can transmit on-site dust images to the pan-tilt unit. If the dust removal effect is not ideal, the staff can remotely adjust the guide rail and telescopic rod 2 according to the on-site image transmission information to change the dust removal angle of the negative pressure ejector dust collector 3, thereby treating dusty areas that are difficult to clean.

[0042] Figure 2The diagram shows a guide rail and telescopic rod, which mainly consists of three parts: guide rail 2-1, sliding module 2-2, and telescopic rod 2-3. Telescopic rod 2-3 is fixed to sliding module 2-2 by fasteners and connected to the middle and rear of the negative pressure jet dust collector via clamps. Telescopic rod 2-3 and guide rail 2-1 adjust the vertical and horizontal angles of the negative pressure jet dust collector, respectively. Conical dust removal is achieved through dust signal transmission and PLC control of guide rail 2-1 and telescopic rod 2-3 at the middle and rear. The required guide rail length is specified. L d Width of the load trolley D c The horizontal range of the dust removal is controlled by the left and right movement of the front and rear guide rails, with an angle range of 0° to 120°. The vertical rotation of the front and rear telescopic rod lifting control device has an angle range of 0° to 60°.

[0043] Figure 3 The diagram shows a multi-stage rotating adhesive dispenser, which mainly consists of seven parts: handle 10-1, rotating shaft 10-2, adhesive dispenser housing 10-3, sealing ring 10-4, inlet 10-5, storage tank 10-6, and baffle 10-7. The handle 10-1 is connected to the rotating shaft 10-2. Rotating the handle 10-1 drives the rotating shaft 10-2, thus switching the type of adhesive and facilitating top-filling. The adhesive is replenished via a nozzle. The rotating shaft 10-2 is connected to the adhesive tank housing 10-3 via a fastener and a telescopic rod. The adhesive tank housing 10-3 and the storage chamber 10-6 are perforated to allow adhesive to be supplied to the infusion tube 10-5. A sealing ring 10-4 is installed at the bottom of the rotating shaft 10-2. A baffle 10-7 is installed inside the storage chamber, and a waterproof strip is installed at the connection between the baffle 10-7 and the storage chamber 10-6. The number of baffle levels can be adjusted as needed. n The adjustment range is 4≤ n ≤8; The operator can control the switching of adhesive via the pan-tilt unit, transmitting signals to the PLC control module to cause the telescopic rod inside the adhesive tank to retract upwards. This causes the sealing ring 10-4 at the bottom of the rotating shaft 10-2 to pull the various adhesives in the storage tank 10-6 upwards. When the sealing ring 10-4 exceeds the position of the inlet 10-5, the adhesive delivery stops. The required baffle length... L b Rotation axis length L x Storage tank height H c And the height of the adhesive box H n The relationship is: H n > H c >L x > L b ,and L b / L x =3 / 5~4 / 5.

[0044] The principle of dust removal using adhesive is as follows: When the high-speed working fluid flows into the precision liquid control device, the water-soluble adhesive is drawn in due to the negative pressure. After the water-soluble adhesive and the working fluid collide and mix violently inside the device, it is further injected into the negative pressure ejector dust collector. The nozzle and dust collection pipe of the negative pressure ejector dust collector are nested together and connected by a fixing component. A dust suction channel is formed between the nozzle and the dust collection pipe. Part of the dust in the air is drawn into the negative pressure ejector dust collector and mixed with the working fluid containing adhesive. Another part of the dust is captured by the atomized liquid sprayed from the diffuser. Due to the influence of air resistance, the droplets can stay in the air for a long time. They have high surface activity and viscosity, which can capture and adsorb dust, causing water droplets and dust to quickly agglomerate and settle, thereby achieving bidirectional dust removal and reducing the dust concentration in the workplace.

[0045] For some hydrophobic dusts, due to the wetting angle >90°, conventional spray dust removal is difficult to achieve effective collision with airborne dust, resulting in poor dust removal efficiency. In practical applications, surfactants such as AES and SDBS need to be added to the dust collector to improve dust collection efficiency. For metal dusts such as aluminum, magnesium, and titanium, explosion accidents may occur when exposed to sparks, electric arcs, or high temperatures. Sodium dihydrogen phosphate can be added to the dust collector to inertize the metal dust and reduce the risk of explosion. For grain dust with good water absorption, solid inert agents such as calcium carbonate, sodium chloride, and sodium bicarbonate can be added to the dust collector. Calcium carbonate and sodium chloride can reduce the concentration of grain dust per unit volume and prevent explosions, while the Na· and Na2O· produced by the decomposition of sodium bicarbonate can combine with the H· and OH· in the grain dust to block the explosion reaction.

[0046] Figure 4 The diagram shows a self-balancing device. The device is fixed to the base plate of the load trolley. The fixing component 12-1 is threadedly connected to the adjusting pipe 12-2 and the hollow pipe 12-3. The adjusting pipe 12-2 has an external thread at the top and an internal thread in the center, with gears 12-2-1 installed on both sides. The hollow pipe 12-3 has a stud 12-3-2 inside and racks 12-3-1 installed on both sides. The diameter ratio between the adjusting pipe 12-2 and the hollow pipe 12-3 is [missing information]. d b1 / d b2=0.7~0.9, the up and down movement of the adjusting tube 12-2 and the hollow tube 12-3 is achieved by the meshing of the thread with the stud 12-3-2 and the meshing between the gear 12-2-1 and the rack 12-3-1; the bottom of the hollow tube 12-3 is provided with a concave fixing buckle, the bottom plate interlayer and the center of the protective shell 12-5 are drilled, and the concave fixing buckle is fixed to the bottom of the protective shell 12-5 through the center through hole; the wheel 12-6 is connected to the protective shell 12-5 through the rotating shaft; the self-balancing device, the level sensor and the PLC control module cooperate with each other to realize the lifting of the self-balancing device.

[0047] Figure 5 The diagram shows a negative pressure ejector dust collector, which mainly consists of seven parts: nozzle 3-1, fixing component 3-2, dust collection pipe 3-3, sludge collection pipe 3-4, sedimentation tank 3-4-1, honeycomb dust suppression net 3-4-2, and diffuser pipe 3-5. The nozzle 3-1, sludge collection pipe 3-4, and diffuser pipe 3-5 are connected by threads, making the device detachable for easy cleaning and replacement. The nozzle and dust collection pipe are nested together and connected by fixing component 3-2, forming a suction channel between them. The size of the suction channel can be adjusted by changing the position of the nut to ensure adequate dust collection in the air. The smooth intake of particles; in traditional dust removal, a single dust removal cycle only involves airflow entering from one end of the equipment and then exiting from the other end after purification; however, bidirectional dust removal has higher dust removal efficiency and a wider range of applications. A single dust removal cycle can effectively purify the airflow twice. When the high-speed working fluid passes through, under the influence of negative pressure, external dust is captured by the working fluid through the suction channel. After being intercepted and settled by the honeycomb dust-reducing net, the working fluid mixed with the dust-adhesive is sprayed out through the diffuser, thereby achieving secondary capture of dust and significantly reducing the dust concentration in the workspace.

[0048] Figure 6 The diagram shows a sludge collection pipe and a honeycomb sludge settling net. The sludge collection pipe contains a sedimentation tank and a honeycomb sludge settling net, which is installed near the diffuser pipe. Because the working fluid is viscous, it experiences viscous resistance in the pipe. The flow velocity of the working fluid differs between the pipe center and the pipe wall; the velocity at the pipe center is greater than the velocity near the pipe wall. Therefore, the sludge settling net is designed as a nine-layer variable-diameter honeycomb structure, with the central mesh diameter smaller than the surrounding mesh. D 9> D 8>…> D 1. While possessing good compressive strength, it can better intercept inhaled dust particles; the length, width, and height of the sedimentation tank are as follows: L j , W j and H j ,Require L jThe length of the sludge collection pipe is 2 / 3 of its total length, the width is the same as the pipe diameter, and the height is 1 / 2 of the width. The length and width of the sedimentation outlet are respectively... L c and W c .

[0049] The self-balancing intelligent vehicle-mounted dust control and removal equipment provided by this invention can be widely used in various dust-generating scenarios such as municipal air purification, mining tunnels, steel smelting plants, and desulfurization and denitrification furnaces. It has a good dust control and removal effect on mine dust, metal dust, grain dust, and inorganic dust. The equipment provided in this example is characterized by its small size, high integration, and intelligence, while also having good inherent safety. It is suitable for various complex dust removal environments, and operators can perform secondary modifications to the equipment, greatly improving the operability of the device and giving it broad application prospects.
