Description

Technical Field

[0001] The invention relates to the technical field of air purification and dust removal, and in particular to a water-saving dust suppression vehicle. Background Art

[0002] With the development of social economy and production, haze often occurs in many areas in northern my country. Haze is a weather phenomenon caused by particles of PM2.5 and other sizes floating in the atmosphere, dust, aerosols and other particles under certain temperature and humidity conditions and relatively stable conditions. Haze has a great impact on people's health and daily life. At present, there are many kinds of vehicles with dust reduction functions, among which sprinklers and fog cannons are the most widely used. Fog cannons have better water-saving effects than sprinklers and better dust reduction effects than sprinklers. However, the particle size of the water mist produced by fog cannons is mostly 100-600 microns, or even above, and the dust adsorption effect is poor. About 50% of the water droplets cannot be effectively used and fall directly on the ground, causing the ground to be slippery. According to aerodynamic theory, when the dust-laden airflow bypasses the droplets, the dust particles will deviate from the circling gas due to inertia and collide with the droplets and be captured. The probability of being captured is related to the diameter of the droplets. When the diameter of the droplets is similar to that of the dust particles, the droplets are more likely to capture dust. Studies have shown that the dust collection effect is best when the ratio of the droplet diameter to the dust particle diameter is within the range of 1.25-5. However, since the diameter of the water mist particles produced by the fog cannon is mostly above 100 microns, it can only capture PM20 or even larger particles, and the dust reduction effect is not ideal for PM2.5-PM10 particles that can be inhaled by the human body.

[0003] When ultrasonic waves propagate in liquids, under the combined effects of mechanical effects, thermal effects, and acoustic cavitation effects, a large number of pores will appear inside the liquid, and at the same time, the intermolecular forces will be destroyed, causing the liquid to disperse and achieving water atomization. Ultrasonic atomization of water can produce 0.5-20 micron water mist, which is much more effective than fog cannons in capturing and reducing dust for PM2.5-PM10 particles that can be inhaled into the human body. Part of the fine mist droplets below 20 microns will evaporate rapidly in the air, causing the relative humidity of the air in the locally enclosed dust-catching space to quickly become saturated. The saturated water vapor condenses with dust particles as nuclei, forming "rain" that falls down, which is particularly effective in suppressing submicron ultra-fine dust. Unlike air purifiers, dust suppression vehicles need to move constantly, and they face the open atmosphere. Therefore, directly applying air purifiers to the atmosphere has extremely limited dust reduction effects and is extremely costly. Summary of the invention

[0026] The present invention will be further described below in conjunction with the accompanying drawings:

[0027] like Figure 1-Figure 9As shown, the water-saving dust suppression vehicle comprises a mobile transport vehicle 1, on which a sealed water tank 2 is arranged, in which a plurality of ultrasonic atomizers 3 arranged in a rectangular array are arranged, and the water in the water tank 2 can immerse the ultrasonic atomizers 3, and the ultrasonic atomizers 3 comprise an atomizing sheet 31, and the atomizing sheet 31 vibrates to make the water atomized and gather on and above the water surface; a mist outlet 4 is opened on the top or upper part of the water tank 2, and the mist outlet 4 is connected to a guide pipe 5, and the guide pipe 5 is arranged on the driving side of the mobile transport vehicle far from the water tank. On the cabin side, at least one fan 6 is provided on the cockpit side of the mobile transport vehicle 1 above the ultrasonic atomizer 3. The wind generated by the fan 6 blows to the water surface and above the water surface and blows the water mist formed on the water surface and above the water surface to the mist outlet 4 and then releases it to the outside atmosphere through the guide pipe 5. The guide pipe 5 has a tendency to gradually narrow from the near water tank side to the far water tank side to ensure the concentration and speed of the water mist when it is released to the outside atmosphere. The distance between the top surface of the atomizer and the water surface is 1cm-6cm, preferably 2cm-5cm. This is because the oscillation energy generated by the atomizer will propagate in the water in a direction perpendicular to the surface of the atomizer. Under the condition of appropriate water depth, the water surface on the energy propagation axis will concentrate on a water column, and a large number of tiny tension waves will occur at the front end of the water column, which greatly reduces the surface tension of the raised water surface. The water surface is split into many tiny areas by the wavelength of the surface tension wave, and each area becomes a microparticle independently as if it is not bonded to each other, and the effect of fog is formed in the air. Through a large number of tests, it is found that when the distance between the top surface of the atomizing sheet and the water surface is 3cm-4.5cm, the atomizing sheet can maintain efficient atomization and form more fine mist. In the present embodiment, a collecting guide bin 7 is provided on the mist outlet 4, and the collecting guide bin 7 is connected to the guide pipe 5. The cross section of the collecting guide bin 7 is larger than the cross section of the guide pipe 5. The collecting guide bin 7 is preferably an arc surface or a spherical surface to avoid water mist retention. In this way, the wind generated by the fan 6 blows to the water surface near the mist outlet 4 and above the water surface, and the water mist formed on the water surface and above the water surface is blown to the collecting guide bin 7 for further gathering and guiding to form high-concentration water mist, which is then concentratedly released to the outside atmosphere through the guide pipe 5 to ensure the concentration of water mist discharged into the air, avoid large amounts of water mist evaporating and dissipating in a short period of time, and achieve rapid saturation of local air relative humidity. The saturated water vapor condenses with dust particles as nuclei to achieve dust reduction effect.

[0028] In one embodiment, the water-saving dust reduction vehicle further includes at least one accelerating fan 8. The wind generated by the accelerating fan 8 further blows the water mist released through the guide pipe 5 to the outside atmosphere, so as to prevent the water mist from gathering around the guide pipe 5 when the mobile transport vehicle 1 is stationary or traveling too slowly, thereby increasing the dust reduction height and dust reduction range of the water mist. The accelerating fan 8 is arranged below the end of the guide pipe 5, and the dust reduction height and dust reduction range of the water mist are adjusted by adjusting the wind speed of the accelerating fan 8. The fan 6 and the accelerating fan are both brushless fans with high wind pressure, high efficiency and long service life.

[0029] In a preferred embodiment, the fan 6 is arranged on the top surface of the water tank 2, and a guide plate 21 is arranged inside the water tank 2. The guide plate 21 extends toward the lower side near the mist outlet to guide the wind generated by the fan to blow obliquely to the water surface and above the water surface, thereby blowing the water mist formed on the water surface and above the water surface to the mist outlet 4. Alternatively, the fan 6 is arranged obliquely in the water tank, so that the wind generated by the fan blows obliquely to the water surface near the mist outlet 4, thereby blowing the water mist formed on the water surface and above the water surface to the mist outlet 4 and then to the collecting guide bin 7 for further gathering and guiding to form high-concentration water mist, and then concentratedly released to the outside atmosphere through the guide pipe 5, instead of directly using an exhaust fan to directly extract the water mist (the water mist concentration cannot be guaranteed, and the service life of the fan is shortened) or making the wind generated by the fan parallel to the water surface, neither of which can achieve the effect of blowing the water mist formed on the water surface and above the water surface to the mist outlet 4 and then to the collecting guide bin 7 for further gathering and guiding to form high-concentration water mist.

[0030] In one embodiment, the water-saving dust suppression vehicle also includes a filter device 11, and the water tank 2 is connected to the filter device 11 to ensure the quality of the ultrasonic atomizer atomized water and extend the service life of the ultrasonic atomizer. Further, the water-saving dust suppression vehicle also includes a water storage container 12 and a water pump 13. The water storage container 12 is connected to the water tank 2 via the water pump 13 and the filter device 11. The water in the water storage container 12 is pressurized by the water pump 13 and filtered by the filter device 11 and then pumped into the water tank. A liquid level sensor is provided in the water tank. The liquid level sensor (not shown in the drawings) and the water pump 13 are both connected to the control system (not shown in the drawings) to ensure that the water in the water tank always submerges the ultrasonic atomizer. The water-saving dust suppression vehicle can continuously generate water mist. Furthermore, the control system can adjust the vibration frequency of the ultrasonic atomizer, thereby adjusting the water mist particle size to produce droplets that are easier to capture dust according to the air quality, further improving the dust reduction, haze reduction, and purification effects, while saving more water.

[0031] In one embodiment, the ultrasonic atomizer 3 is directly connected to the side wall and / or bottom wall of the water tank, and the ultrasonic atomizer is provided in several rows, and the height of each row of ultrasonic atomizers 3 is basically the same to prevent the ultrasonic atomizer from colliding and overturning during the movement of the mobile transport vehicle 1. An overflow port (not shown in the drawings) is provided on the water tank to prevent the water level from being too high. Or the ultrasonic atomizer is arranged in a floating manner in the water tank; when the ultrasonic atomizer is arranged in a floating manner in the water tank, a hollow floating adjustment chamber 9 is also provided in the water tank 2, and the floating adjustment chamber 9 is floated or suspended in the water of the water tank. By mounting the ultrasonic atomizer 3 on the floating adjustment chamber 9, the atomizer sheet 31 is suspended in the water. The floating adjustment chamber 9 is filled with liquid or foam or solid filler. The distance between the top surface of the atomizer sheet 31 and the water surface is adjusted by adjusting the liquid content or foam content or solid filler in the floating adjustment chamber, so that the buoyancy of the atomizer sheet together with the floating adjustment chamber and its own gravity reach a specific dynamic balance, so that the atomizer sheet can be adaptively adjusted according to the water level change, and the distance between the top surface of the atomizer sheet and the water surface is always maintained between 3cm-4.5cm. The atomizer sheet is always suspended in the water and continuously and efficiently produces fine mist. The floating adjustment chamber adjusts the position of the atomizer sheet with a simple structure and low cost. Furthermore, a water injection port 91 or a filling port is provided on the side wall or the top surface of the floating adjustment chamber 9, and each ultrasonic atomizer 3 is evenly mounted on at least two floating adjustment chambers 9, and a recessed portion 92 is provided on the floating adjustment chamber, and the ultrasonic atomizer 3 is fixed and mounted on the recessed portion 92 of the floating adjustment chamber, and the cross-section of the floating adjustment chamber is basically rectangular, semicircular, semi-elliptical or fan-shaped, so the floating adjustment chamber and the ultrasonic atomizer 3 are not easy to overturn. A plurality of partitions 14 can also be provided in the water tank 2, and the ultrasonic atomizer can be placed just between two adjacent partitions 14, and the slits formed by the adjacent partitions are interconnected, and the extension direction of the partition is perpendicular to the travel direction of the mobile transport vehicle 1, and the ultrasonic atomizer is limited by the partition 14 to prevent the ultrasonic atomizer from colliding and overturning during the travel of the mobile transport vehicle 1.

[0032] In a preferred embodiment, the flow guide pipe 5 is adjustable in height up and down, and the collecting guide bin 7 can rotate horizontally, so that even if the mobile transport vehicle is stationary, air purification can be achieved at different heights and different horizontal positions, further improving the dust reduction, haze reduction, and purification range. Specifically, an annular groove 22 can be provided on the mist outlet 4 of the water tank 2, and a collecting guide bin cover that is basically an arc or spherical is provided on the annular groove 22. The collecting guide bin 7 rotates along the annular groove 22, driving the flow guide pipe 5 to rotate horizontally to purify the air of the mobile transport vehicle 360 ​​degrees (including the sides and rear). Or the collecting guide bin is provided on the mist outlet 4 through a rotatable cover of a bearing, so that the rotation of the flow guide pipe 5 is smoother. Furthermore, an angle adjustment groove 71 is opened on the collecting guide bin 7, and an extension cover 72 that cooperates with the inner wall of the collecting guide bin is provided on the side of the guide pipe 5 near the collecting guide bin. The extension cover 72 is inserted into the angle adjustment groove 71 and rotates up and down along the angle adjustment groove 71, thereby driving the guide pipe 5 to rotate up and down, thereby realizing air purification at different heights and different horizontal positions, further improving the dust reduction, haze reduction, and purification range. The up and down rotation range of the guide pipe 5 is 5°-85°, and the guide pipe can be rotated to a nearly horizontal state, or it can be rotated to a basically vertical state. The dust reduction height and dust reduction range of this water-saving dust reduction vehicle are wide.
