Description

Technical Field

[0001] The present invention relates to the field of separation technology, in particular to an atomizing dust reduction device for construction engineering. Background Art

[0002] Construction dust is an important source of air pollution, especially in windy weather. A large amount of fine particulate matter such as PM10 and PM2.5 will endanger the respiratory health of construction workers and surrounding residents. On the other hand, environmental protection policies are becoming increasingly stringent. Dust removal is the key to implementing pollution prevention and control requirements. Reducing dust can improve urban air quality, reduce the risk of haze, and protect the quality of the surrounding living environment. Therefore, more attention is now paid to dust removal at construction sites.

[0003] However, in the existing technology, when dust reduction is carried out at construction sites, dust particles are easily suspended for a long time and accumulate static electricity due to friction. In addition, hydrophobic substances such as grease and dust are often attached to the surface, which causes repulsion or wetting resistance between the dust particles and the water mist, making it difficult to adsorb the water mist through surface tension. This ultimately leads to low dust particle adsorption efficiency and poor dust removal effect. Summary of the Invention

[0004] The object of the present invention is to provide an atomizing dust suppression device for construction engineering, which solves the problems of low dust particle adsorption efficiency and poor dust removal effect in the prior art.

[0009] Furthermore, a plurality of electrostatic generators are embedded on the upper surface of the arc-shaped adsorption plate.

[0010] Furthermore, a working net cylinder is connected to the working cylinder, the fixing ring is arranged on the outer surface of the working net cylinder, and a plurality of flow holes are opened in the working cylinder.

[0015] According to the above technical features, the beneficial effects of the present invention are as follows: the present invention provides an atomizing dust reduction device for construction engineering construction. Through the coordinated work between the wind guide component, the adsorption component and the atomizing component, the multi-layered adsorption component can increase the adsorption area and improve the dust capture efficiency; traditional technology requires continuous spraying to maintain the dust reduction effect, resulting in a large consumption of water resources.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0021] Example: Please refer to Figure 1-Figure 3 An embodiment of the present invention provides an atomizing dust suppression device for construction engineering, which includes: a controller and a working cylinder 1. The working cylinder 1 includes at least a wind guide component 2, an adsorption component 3, and an atomizing component 4 electrically connected to the controller. The wind guide component 2 is coaxially connected to the bottom of the working cylinder 1, and the atomizing component 4 is connected to the center of the working cylinder 1. The adsorption component 3 is annular and coaxially embedded in the middle of the working cylinder 1. The multiple layers of adsorption components 3 are arranged in parallel and at intervals. The wind guide component 2 and the atomizing component 4 work alternately.

[0022] It should be noted that an embodiment of the present invention provides an atomizing dust reduction device for construction engineering construction, comprising a working cylinder 1, an air guide component 2, an adsorption component 3, an atomizing component 4 and a controller, wherein the air guide component 2 is used to attract dust into the device to achieve dust removal, the adsorption component 3 realizes the adsorption and collection of dust particles, and the atomizing component 4 is used to assist in achieving the descent of dust particles. In detail, the outer shape of the working cylinder 1 is preferably cylindrical; the wind guide component 2 attracts dust particles in the construction site into the working cylinder 1 by generating an airflow of a specified speed; the multi-layer adsorption components 3 are arranged in parallel and at intervals, which can form a layered adsorption effect, and the inner side of the multi-layer adsorption components 3 is connected to a device that can generate static electricity. The device attracts and collects dust particles by releasing an electrostatic field of a specified intensity. By attracting dust particles to the adsorption component 3, the mass of dust attached to the inner surface of the working cylinder 1 can be reduced as much as possible, thereby extending the service life of the adsorption component 3; the atomization component 4 releases water mist particles above the working cylinder 1, so that the water mist particles are fully in contact with the suspended dust in the air and help promote its sedimentation. The combination of the atomization component 4 and the wind guide component 2 can enhance the efficiency of dust particle landing and adhesion. The present invention provides an atomization dust reduction device for construction engineering construction, which solves the problems of low dust particle adsorption efficiency and poor dust removal effect in the prior art.

[0023] In some embodiments, the adsorption assembly 3 includes at least a fixing ring 5 and an electrical attachment 6. The inner diameter of the fixing ring 5 is larger than the inner diameter of the working cylinder 1, which not only ensures the smooth passage of airflow, but also ensures that sufficient space is provided to accommodate other components and improve the adsorption efficiency. The electric attachment 6 includes at least a limit plate 7, an arc-shaped adsorption plate 8, a vibrator 9, a dust collecting pipe, and a storage cylinder 10; wherein the limit plate 7 is parallel to the arc-shaped adsorption plate 8 and is spaced apart to form a space for the vibrator 9 to complete the vibration movement; wherein, a plurality of electrostatic generators 15 are embedded on the upper surface of the arc-shaped adsorption plate 8, and the electrostatic field intensity generated by the electrostatic generator 15 is controlled by the controller and can be dynamically adjusted according to the particle size and concentration of the dust particles. It should be noted that the outer circle height of the arc-shaped adsorption plate 8 is higher than the height of the middle position, that is, it is a basin-shaped structure with a depression in the middle. When the electrostatic generator 15 is powered off, the arc-shaped adsorption plate 8 uses the high-frequency vibration of the vibrator 9 to make the dust particles approach the depressed position in the middle, and transport them along the dust collecting pipe to the storage cylinder 10, thereby completing the centralized collection and storage of the adsorbed dust particles.

[0024] In some embodiments, the dust extraction pipe includes at least a first pipe section 11, a second pipe section 12, and a third pipe section 13. When the vibrator 9 is working, the first pipe section 11 makes a spiral motion on the end face of the second pipe section 12, which can promote the transportation of dust particles to the designated area; when the vibrator 9 stops working, the first pipe section 11 and the second pipe section 12 are coaxial, which can promote the collection of dust particles; the spiral motion between the first pipe section 11 and the second pipe section 12 is driven by a built-in micro motor, and the micro motor is electrically connected to the controller, and can adjust the spiral angle and speed according to the characteristics of the dust particles, thereby improving the dust particle collection efficiency.

[0025] Preferably, the working cylinder 1 is made of high-strength lightweight alloy, and its inner wall is coated with an epoxy resin-based anti-corrosion coating with a thickness ranging from 0.2 mm to 0.5 mm. The anti-corrosion coating can effectively extend the service life of the working cylinder 1.

[0026] Preferably, the fixing ring 5 is made of antistatic material to avoid interference with the adsorption process due to its own charge; the fixing ring 5 is fixedly connected to the inner wall of the working cylinder 1 by bolts or welding.

[0027] Preferably, the spiral motion is driven by a vibrator 9, and the vibrator 9 adjusts the vibration frequency in real time by a controller according to the concentration of particulate matter. The preferred amplitude range is 0.1mm to 1mm, and the frequency range is 50Hz to 200Hz, thereby ensuring that dust particles enter the recessed area of ​​the arc-shaped adsorption plate 8.

[0028] Preferably, a mass detector is connected to the bottom of the arc-shaped adsorption plate 8 .

[0029] In some embodiments, the wind guide assembly 2 includes at least a speed regulator, a guide fan and a protective mesh cover. The working cylinder 1 is connected to a wind speed sensor. The speed regulator is electrically connected to the wind speed sensor and is used to dynamically adjust the working state of the guide fan according to the wind speed data detected in real time. The speed regulator controls the guide fan to generate an airflow with a specified flow rate, sucking the dust particles in the construction site into the working cylinder 1 so that the dust particles can contact the arc-shaped adsorption plate 8. The airflow speed is detected by the wind speed sensor and accurately controlled by the speed regulator, so that the airflow is always maintained within the optimal working range, thereby promoting the dust particles to be efficiently guided to the action area of ​​the adsorption assembly 3; for example, in strong wind weather conditions, when the wind speed sensor detects that the external wind speed is high, the speed regulator will reduce the speed of the guide fan to avoid excessive airflow causing the spread of floating dust; and in no wind or light wind conditions, the speed regulator increases the speed of the guide fan to ensure that the airflow is sufficient to introduce floating dust into the working cylinder 1.

[0030] Preferably, the speed range of the guide fan is preferably set to 1000 rpm to 3000 rpm, which can cover the requirements of dust particle concentration and ambient wind speed in different construction sites.

[0031] Preferably, the protective mesh cover is made of metal, and the mesh size is preferably 2mm×2mm, which can prevent foreign matter from entering the working cylinder 1 and interfering with the normal operation of other components.

[0032] In some embodiments, the atomization assembly 4 includes at least a water mist head, a pressure regulator, and a water volume regulator. The water mist head includes a diversion chamber for distributing liquid pressure. The diversion chamber preferably has a diameter ranging from 5 mm to 10 mm, allowing the water mist particles to cover the entire cross-section of the working cylinder 1. The pressure regulator preferably has an adjustment range of 0.1 MPa to 0.5 MPa, and the water volume regulator preferably has an adjustment range of 1 L / min to 5 L / min. The specific parameters are dynamically adjusted based on the humidity and dust concentration of the construction site. For example, in low-humidity environments, the controller automatically increases the water mist volume to compensate for the difficulty in dust reduction caused by dry air; in high-humidity environments, the water mist volume is reduced to avoid wasting water resources.

[0033] In detail, the atomizing component 4 releases water mist particles to the top of the working cylinder 1, so that the water mist particles are in full contact with the suspended dust in the air and help promote its sedimentation. The atomizing component 4 and the wind guide component 2 work alternately, that is, when the wind guide component 2 guides the airflow, the atomizing component 4 pauses; when the wind guide component 2 pauses, the atomizing component 4 starts to generate water mist. The alternating mode can ensure the synergistic effect of airflow guidance and water mist dust reduction, and can further enhance the landing and adhesion efficiency of dust particles, thereby maximizing the dust reduction effect.

[0034] In some embodiments, the working cylinder 1 is provided with a plurality of flow holes 17, which ensure uniform airflow distribution while preventing dust particles from escaping. The provision of the working net cylinder 16 allows dust particles to be further captured after the adsorption assembly 3 is activated, reducing the possibility of dust particles re-entering the air. It can also effectively intercept some larger particles, reducing the workload of the adsorption assembly 3.

[0035] In some embodiments, a protective cover is detachably connected to the top of the working cylinder 1, preferably made of a transparent material, which can facilitate observation of the working status of the internal components; the protective cover can be connected to the working cylinder 1 through a snap-fit ​​structure, which is simple to operate and has good sealing performance. A mobile support frame is connected to the bottom of the working cylinder 1, and a load-bearing box is connected to the mobile support frame; a lifter is connected between the mobile support frame and the working cylinder 1, which can facilitate adjustment of the height of the device to meet the needs of different construction scenarios. The mobile support frame is connected to a detection window, which includes at least an infrared detector and a detector electrically connected to the controller. The detector includes a coaxially connected induction shell and an induction core tube. When the detection window is opened, the induction core tube extends out of the induction shell. A particle collection groove is provided on the outer wall of the induction core tube to receive dust particles. An adhesion layer is provided on the side wall of the particle collection groove. The adhesion layer is made of a hydrophilic material with a thickness preferably ranging from 0.1mm to 0.5mm. Dust particles stick to the adhesion layer, which can effectively capture dust particles suspended in the air. Infrared detectors and detectors can monitor the dust concentration at the construction site in real time. Double detection and verification can provide more accurate data support for environmental management. The detectors capture dust particles in the air through particle collection troughs and feed the data back to the controller, which is then used to analyze the air quality change trends at the construction site.

[0036] It should be noted that the present invention has conducted corresponding tests. In the first set of experiments, the construction conditions of the test were: 4 square meters of area, wind speed of 3.4 meters per second, horizontal diffusion speed of dust particles of 3.0 meters per second, water mist flow rate of 30L / h, water mist pressure of 0.3MPa, and other parameters were the same; the prior art control group A was: an atomizing nozzle was set in the center of the construction area; the test group B of the technical solution of this application was: a device of this invention was set in the center of the construction area, and the fan speed was a wind speed of 3.5 meters per second. One of the test results is shown in the following table: index Control group A Experimental group B PM10 concentration (μg / m³) 75 40 PM2.5 concentration (μg / m³) 40 20 Sedimentation per unit area (g / m²・h) 1.2 2.5 Sedimentation rate (mg / m²・min) 20 41.7 In this set of experiments, the device provided by the present invention can enhance airflow disturbance, promote the contact between tiny water mist and PM2.5 particles, make the water mist coverage more uniform, increase the probability of collision with PM10 particles, shorten the sedimentation time, increase the sedimentation rate, make the sedimentation more complete, and effectively increase the sedimentation amount per unit area.

[0037] It should be noted that in the second set of experiments, the construction conditions were: a 4-square-meter area, a wind speed of 3.4 m / s, a horizontal diffusion speed of 3.0 m / s for dust particles, a water mist flow rate of 30 L / h, a water mist pressure of 0.3 MPa, and the other parameters were the same; the prior art control group A was: an atomizing nozzle was set in the center of the construction area; the experimental group B of the technical solution of this application was: a device of this invention was set in the center of the construction area, the fan speed was 3.5 m / s, the electric field strength was 8 kV / cm, and the wind guide component 2 and the atomizing component 4 worked alternately. The results of one of the experiments are shown in the following table: index Control group A Experimental group B PM10 concentration (μg / m³) 75 30 PM2.5 concentration (μg / m³) 40 15 Sedimentation per unit area (g / m²・h) 1.2 3.2 Sedimentation rate (mg / m²・min) 20 53.3 In this group of experiments, the device provided by the present invention can disturb PM10 to make it diffuse more evenly and the water mist cover more fully, and the electrical attachment device 6 can further reduce the escape of unsettled PM10 particles; PM2.5 particles are small in size and difficult to settle, and the electrical attachment device 6 in this device provides an 8kV / cm electrostatic field to effectively enhance the adsorption force between the particles and the water mist after they are charged, and the PM2.5 concentration capture efficiency is greatly improved; the adsorption component 3 and the atomization component 4 can work together to capture more dust, and the wind guide component 2 and the atomization component 4 work alternately to reduce airflow interference, and the dust is settled more thoroughly, and the settling amount per unit area is effectively increased; alternating work shortens the ineffective diffusion time of dust in the area, and static electricity accelerates the adsorption and sedimentation of small particles, thereby improving the overall sedimentation efficiency and speeding up the rate.

[0038] It should be noted that in the third group of experiments, the construction conditions were: a 4-square-meter area, a wind speed of 3.4 m / s, a horizontal diffusion speed of dust particles of 3.0 m / s, and the other parameters were the same; the prior art control group A was: an atomizing nozzle was set in the center of the construction area, the water mist flow rate was 30 L / h, and the water mist pressure was 0.3 MPa; the experimental group B of the technical solution of this application was: a device of this invention was set in the center of the construction area, the fan speed was 3.5 m / s, the electric field strength was 8 kV / cm, and the atomizing component 4 was not working. The results of one of the experiments are shown in the following table: index Control group A Experimental group B PM10 concentration (μg / m³) 75 25 PM2.5 concentration (μg / m³) 40 10 Sedimentation per unit area (g / m²・h) 1.2 3.8 Sedimentation rate (mg / m²・min) 20 63.3 In this set of experiments, the water mist used in the existing technology (Control Group A) had a limited diffusion range, and some PM10 escaped with the airflow. However, the wind guide component 2 of the present device (Test Group B) actively attracted PM10, enhancing adsorption through the electrostatic field, effectively reducing the residual PM10 concentration. PM2.5 particles are small in size and have weak inertia, making the passive collision capture efficiency of the water mist in the existing technology low. The electrostatic field of the adsorption component 3 in the present device charged PM2.5, effectively adsorbing them and significantly reducing PM2.5 concentrations. The wind guide component 2 in the present device actively attracted more dust, while electrostatic adsorption reduced particle escape, increasing the total amount of settled dust and achieving a significantly higher amount per unit area than the existing technology. The wind guide component 2 in the present device shortened the diffusion time of dust within the area, and electrostatically accelerated particle adsorption and deposition, improving overall settling efficiency and achieving a significantly faster rate than the existing technology. This addresses the issues of dust escape and insufficient capture of small particles in the passive dust settling technology.
