Description

Technical Field

[0001] The present invention relates to the technical field of dust removal, and in particular to a dust removal system and a use method thereof. Background Art

[0002] In the vast field of modern industrial production, especially those involving high-temperature process operations and material handling, dust and heat pollution problems have become increasingly prominent, becoming a key factor restricting production efficiency, harming the environment and employee health. Although traditional dust removal technology can alleviate dust pollution to a certain extent, its inherent limitations and shortcomings are becoming more and more obvious, especially when dealing with complex and changeable airflow environments. The design of traditional dust hoods, such as the common rectangular receiving hood, is mainly based on the simple concept of airflow interception, capturing dust-laden airflow through the negative pressure effect formed at the opening of the hood. This design may be effective when dealing with low-intensity and low-temperature airflows, but its effect is greatly reduced when facing the strong hot jets generated by high-temperature operations and the accompanying high-speed material-induced airflow. The dust in the hot jet often has a large momentum due to its high temperature and high speed, and is prone to deflection during the rising process, especially in the application scenario of high-hanging hoods, where this deflection phenomenon is more significant. Because the high-hanging hood is far away from the heat source, its ability to capture hot jets and dust particles is limited, and it is easily disturbed by the surrounding lateral airflow, making the dust leakage problem particularly serious. To compensate for this shortcoming, traditional dust hoods often need to increase the exhaust volume to counteract airflow deviation and leakage with stronger suction. However, this practice not only greatly increases energy consumption, leading to rising operating costs, but also increases the operating noise of the fan, posing a serious threat to the quietness of the production environment and the hearing health of employees. In addition, excessive exhaust volume may also cause air flow disorder in the factory, affecting the normal operation of other production equipment and the production quality of products. Summary of the invention

[0003] In view of this, the present invention provides a dust removal system and a method of use to solve the problem that when high-temperature operations are performed, strong thermal jets and accompanying high-speed material-induced airflows will be generated. The dust in the thermal jets often has a large momentum due to its high temperature and fast speed, and is easily deflected during the rising process. The existing high-hanging hoods are far away from the heat source and are disturbed by the lateral airflow, resulting in poor dust removal effect.

[0004] In a first aspect, the present invention provides a dust removal system, comprising:

[0005] A dust collection component, the dust collection component comprising a dust collection duct, the dust collection duct being adapted to be disposed in correspondence with a pollution source, the suction force generated in the dust collection duct driving the dust generated by the pollution source to enter;

[0006] A blower, the blower is arranged on the side of the pollution source, and the blower generates wind toward the pollution source;

[0007] A flow guide component is arranged between the pollution source and the blower.

[0008] The hair dryer generates lateral wind directly toward the pollution source, and the guide component is used to block the wind generated by the hair dryer from blowing directly toward the pollution source, so that the wind generated by the hair dryer bypasses the guide component and then blows toward the pollution source. The air pressure in the area between the pollution source and the guide component is a first pressure, and the value of the first pressure is smaller than the pressure value of the surrounding area.

[0009] When the pollution source releases high-temperature particulate pollutants and hot jets, the lateral airflow is guided by the guide component to change its direction. When the lateral wind passes over the guide component, an area is formed between the guide component and the pollution source. The air pressure in this area is a first pressure, and the value of the first pressure is smaller than the value of the second pressure in the surrounding area. As a result, the dust is subjected to lift. The generated lift, combined with the action of the hot air flow and the suction force of the dust collection duct, causes the pollutants to move toward the upper dust collection duct, thereby achieving a stronger dust collection effect.

[0010] In an optional embodiment, the guide assembly includes a guide combination plate, and the guide combination plate is arc-shaped.

[0011] In an optional embodiment, the guide assembly also includes a power member, the guide combination plate includes a first guide plate and a second guide plate, the power member is arranged at one end of the guide combination plate, and the power member drives the first guide plate to move along the length direction of the second guide plate; or, the power member drives the second guide plate to move along the length direction of the first guide plate; or, the power member drives the first guide plate and the second guide plate to move in opposite directions along their own lengths.

[0012] In an optional embodiment, the guide assembly plate has an arc-shaped accommodating space, and the pollution source is accommodated in the arc-shaped accommodating space.

[0013] In an optional embodiment, the pollution source is square, and the curvature of the guide assembly plate is Wherein, L is the side length of the pollution source (2), X and Y are the arc coordinates of the guide assembly plate (3), respectively (0≤Y≤1.6L, -1.6L≤X≤1.6L).

[0014] In an optional embodiment, the dust collection assembly also includes a dust collecting hood, which is arranged above the pollution source, and the bottom surface of the dust collecting hood is arranged at the same height as the top surface of the guide combination plate; or, the bottom surface of the dust collecting hood is lower than the top surface of the guide combination plate.

[0015] In an optional embodiment, the dust suction duct includes a vertical section and a transverse section, the vertical section is fixedly connected to the dust collecting hood, and an exhaust fan is provided in the vertical section.

[0016] In an optional embodiment, the dust collection assembly further includes a dust box, which is connected to the transverse section and is used to accommodate dust.

[0017] In an optional embodiment, the dust collection assembly further includes a filter screen, and the filter screen is arranged in the transverse section.

[0018] In the second aspect, the present invention also provides a method for using a dust removal system, wherein a blower generates lateral wind directly toward a pollution source, and a guide component is used to block the wind generated by the blower from blowing directly toward the pollution source, so that the wind generated by the blower bypasses the guide component and then blows toward the pollution source, and the air pressure in the area between the pollution source and the guide component is a first pressure, and the value of the first pressure is less than the value of the second pressure in the surrounding area.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] Example

[0040] Combine the following Figures 1 to 8 , describing an embodiment of the present invention.

[0041] According to an embodiment of the present invention, on the one hand, a dust removal system is provided, comprising: a dust suction component, comprising a dust suction duct 1, the dust suction duct 1 is suitable for being arranged corresponding to a pollution source 2, the suction force generated in the dust suction duct 1 is used to drive the dust 9 generated by the pollution source 2 to enter; a blower, arranged on the side of the pollution source 2, the blower generates wind toward the pollution source 2; and a flow guide component, the flow guide component is arranged between the pollution source 2 and the blower.

[0042] The hair dryer generates a lateral wind 8 (horizontally arranged in the present application) directly toward the pollution source 2, and the guide component blocks the wind generated by the hair dryer from blowing directly toward the pollution source 2, so that the wind generated by the hair dryer bypasses the guide component and then blows toward the pollution source 2, and the air pressure in the area between the pollution source 2 and the guide component is a first pressure, and the value of the first pressure is less than the pressure value of the surrounding area. Specifically, the hair dryer is a high-speed fan to generate a lateral wind with a relatively strong wind speed. It should be noted that in the present embodiment, the dust collection duct 1 is located above the pollution source 2, and the hair dryer is located on the side of the pollution source 2, and the value of the first pressure is less than 0MPa (that is, the first pressure is a negative pressure).

[0043] When the pollution source 2 releases high-temperature particulate pollutants and hot jets, the lateral wind is guided by the guide component to change its flow direction. When the lateral wind 8 passes over the guide component, an area is formed between the guide component and the pollution source 2. The air pressure in this area is a first pressure, and the value of the first pressure is smaller than the value of the second pressure in other surrounding areas, thereby causing the dust 9 to be subjected to lift. The generated lift, combined with the action of the hot air flow and the suction of the dust collection duct 1, causes the pollutants to move toward the upper dust collection duct 1, thereby achieving a stronger dust collection effect.

[0044] In one embodiment, Figure 1 As shown, the guide assembly includes a guide assembly plate 3, which is arc-shaped. The arc-shaped guide assembly plate 3 can better guide the flow of the lateral wind 8. The unique arc structure of the guide assembly plate 3 can cleverly guide the airflow generated by the lateral wind 8 to bypass its surface, thereby inducing a strong upward airflow in the key area between the guide assembly plate 3 and the pollution source 2.

[0045] In one embodiment, Figure 2 As shown, the guide assembly also includes a power piece 303, and the guide assembly 3 includes a first guide plate 301 and a second guide plate 302. The power piece 303 is arranged at one end of the guide assembly 3, and the power piece 303 drives the first guide plate 301 to move along the length direction of the second guide plate 302, that is, the first guide plate 301 moves and the second guide plate 302 does not move, thereby adjusting the overall length of the guide assembly 3. Specifically, the power piece 303 is a telescopic hydraulic cylinder. It should be noted that the first guide plate 301 and the second guide plate 302 are connected by a sliding rail connection. It should be noted that the first guide plate 301 and the second guide plate 302 are both high-temperature resistant thin steel coils. The application of high-temperature resistant thin steel coils enables the baffle assembly to withstand high temperature environments, reduces material deformation or damage caused by high temperature, and thus extends the service life.

[0046] In one embodiment, Figure 1 As shown, the guide assembly plate 3 has an arc-shaped accommodation space, and the pollution source 2 is accommodated in the arc-shaped accommodation space, so that all the dust 9 generated by the pollution source 2 can be accommodated in the arc-shaped accommodation space to avoid arbitrary diffusion of the dust 9.

[0047] In the traditional dust collection process, in theory, as long as the exhaust volume of the dust hood 4 is equal to the flow rate of the hot jet on the cross section of the hood, and the cross-sectional size of the dust hood 4 is equal to the size of the hot jet on the cross section of the hood opening, the polluted airflow will be completely eliminated. However, in fact, due to the influence of the cross-flow airflow, the hot jet will be deflected and the unmanned airflow will overflow into the room, and the higher the installation height of the dust hood 4, the more serious the influence of the cross-flow airflow. Therefore, the hood opening size and exhaust volume of the dust hood 4 in industrial production should be increased. In this application, by setting the guide assembly plate 3 to eliminate the cross-flow formed by the lateral wind 8, the pollution source 2 is accommodated in the arc-shaped accommodation space, the hood opening size of the dust hood 4 can be reduced, and there is no need for a large exhaust volume, which reduces the dust removal system's dependence on large air volume and high wind speed. Under the premise of the same dust removal effect, the energy consumption of the blower that generates the lateral wind 8 is significantly reduced, thereby reducing the operating cost of the enterprise, and the reduction of the fan operation load directly reduces noise pollution, providing employees with a comfortable working environment and realizing green production of the enterprise.

[0048] In one embodiment, Figure 1 As shown, the pollution source 2 is square, and the curvature of the guide assembly plate 3 is Wherein, L is the side length of the pollution source 2, X and Y are the arc coordinates of the guide plate 3, that is, the arc coordinates are a coordinate system with the center point of the pollution source 2 as the origin, and the coordinate system is set horizontally (X is the distance from the origin to the midpoint of the arc, and Y is the distance from the origin to the end point of the arc), (0≤Y≤1.6L, -1.6L≤X≤1.6L). By giving the calculation formula of the guide plate 3, guidance is provided for the design of the guide plate 3, so that the on-site personnel can select the corresponding guide plate 3 according to the formula and the size of the pollution source 2.

[0049] In one embodiment, Figure 1 As shown, the dust collection assembly also includes a dust collecting hood 4, which is arranged above the pollution source 2, and the bottom surface of the dust collecting hood 4 is arranged at the same height as the top surface of the guide assembly plate 3. It should be noted that the bottom surface of the dust collecting hood 4 is arranged to fit the top surface of the guide assembly plate 3, so that the dust 9 in the accommodating space of the guide assembly plate 3 can smoothly enter the integrated hood.

[0050] In one embodiment, Figure 1 As shown, the dust collection duct 1 includes a vertical section 101 and a horizontal section 102. The vertical section 101 is fixedly connected to the dust collecting hood 4. An exhaust fan 7 is arranged in the vertical section 101. The exhaust fan 7 generates suction force, so that the airflow outside the dust collecting hood 4 enters the dust collecting hood 4 under the action of the exhaust fan 7. Specifically, the exhaust fan 7 is a fan.

[0051] In one embodiment, Figure 1As shown, the dust collection assembly also includes a dust box 6, which is connected to the transverse section 102 and contains dust. By setting the dust box 6, the dust 9 outside the dust collecting hood 4 enters the dust box 6 through the vertical section 101 and the transverse section 102 in sequence. It should be noted that after the gas carrying the dust 9 enters the dust box 6, it is filtered by the dust box 6 and discharged from the working area after the gas is purified.

[0052] In one embodiment, Figure 1 As shown, the dust collection assembly further includes a filter screen 5 , which is disposed in the transverse section 102 , and the gas before entering the dust box 6 is preliminarily filtered through the filter screen 5 .

[0053] In order to realize automatic control, a controller is also included, and the controller is connected to the exhaust fan 7 and the hair dryer circuit respectively.

[0054] A method for using a dust removal system comprises the following steps: (1) adjusting the length of a guide assembly plate 3 by means of a power member 303 so that the top surface of the guide assembly plate 3 fits with the bottom surface of a hood opening of a dust collecting hood body 4, and a pollution source 2 is accommodated within the accommodation space of the guide assembly plate 3; (2) a controller turns on a blower to generate lateral wind 8, and turns on an exhaust fan 7 to allow the airflow outside the dust collecting hood body 4 to enter the dust collection duct 1.

[0055] In this embodiment, as follows Figure 3 As shown, the indoor flow trajectory of the dust removal system provided in this embodiment is simulated. Figure 3 It is clearly shown that the flow path of the lateral airflow generated by the hair dryer changes significantly when passing through the guide assembly plate 3. Due to the arc-shaped setting of the guide assembly plate 3, the lateral airflow is guided to bypass its surface, inducing a strong upward airflow in the area of ​​the guide assembly plate 3 and the pollution source 2, which significantly enhances the airflow's ability to capture and carry polluted dust 9, ensuring that the dust 9 can flow into the dust collecting hood 4 more efficiently and directionally, thereby achieving a significant improvement and optimization of air quality.

[0056] In this embodiment, as follows Figure 4As shown, it is a cloud diagram of the gas movement speed at various positions of the dust removal system after the hair dryer of this embodiment generates a lateral wind of 1 m / s. It can be seen from the figure that after adding the guide combination plate 3, the airflow blown out by the lateral wind with an initial wind speed of 1 m / s quickly decreases to about 0.2 m / s after passing through the guide combination plate 3, thereby achieving effective deceleration and direction adjustment of the airflow. It should be noted that, due to the complex interaction of the airflow, the area between the guide assembly plate 3 and the pollution source 2 forms two significant vortex structures - one large and one small, i.e., the first vortex 10 and the second vortex 11. The first vortex 10 is a large vortex structure and the second vortex 11 is a small vortex structure. The vortex synergy of the first vortex 10 and the second vortex 11 effectively sucks the airflow containing dust 9 above the pollution source 2 and guides it upward until it is sent into the dust collecting hood 4, and then it is completely removed from the room through the filter screen 5 and the dust collecting box 6, thereby achieving effective isolation and removal of pollutants. The design of the present application not only optimizes the indoor airflow organization, but also significantly improves the air purification efficiency and indoor environmental quality.

[0057] In this embodiment, as follows Figure 5 As shown in the figure, it is a pressure cloud diagram of the air pressure at various positions of the dust removal system after the hair dryer of this embodiment generates lateral wind. The figure shows in detail the characteristics of the pressure field in the dust removal system, and especially points out that on the left and right sides of the guide assembly plate 3, especially on the side close to the lateral wind, the pressure level is significantly higher than the area below the guide assembly plate 3, forming an obvious pressure gradient difference. Through further observation, it can be found that from the pollution source 2 to the hood opening of the dust hood body 4, the pressure gradient gradually decreases from strong to weak. This feature is particularly significant on the left side of the guide plate, where a clear negative pressure area is formed. It is precisely because of the existence of this negative pressure area that a strong traction force is generated on the pollutant particles, prompting them to be quickly and efficiently sucked into the dust hood body 4, and then completely removed from the room through the filter screen 5 and the dust box 6. This cloud diagram strongly proves the excellent performance and superiority of the dust removal system of this embodiment in negative pressure dust removal.

[0058] In this embodiment, as follows Figure 6As shown in a-6e, it is a schematic diagram of the single coupling effect of the dust removal system for dust particles 9 in the particle size range of 0.5-30μm. The figure clearly shows that under the interference of the lateral wind, more than 85% of the pollutant particles with a particle size between 0.5μm and 10μm are captured by the high-efficiency dust removal hood, and then safely discharged out of the room through the purification and filtration mechanism composed of the filter 5 and the dust collection box 6. For pollutant particles in a larger particle size range (10μm-30μm), although their mass is relatively heavy, thanks to the airflow power generated by the negative pressure effect of the guide assembly plate 3, the effective removal of most particles can be achieved. In general, the dust removal system provided in this embodiment shows an excellent capture and processing capability for pollutant particles in the full particle size range of 0.5 to 30μm released by the pollution source 2, and the overall capture efficiency exceeds 80%, with a significant dust removal effect, providing a solid guarantee for creating a clean and healthy indoor environment.

[0059] Comparative Example

[0060] In this comparative example, the structure of the dust removal system is the same as that of the embodiment of the present application except that the combined guide plate 3 is not provided.

[0061] In this embodiment, as follows Figure 7 As shown in a-7b, Figure 7 a. Figure 7 b shows that under the same wind speed conditions, Figure 7 a is a cloud diagram of the temperature distribution above the pollution source 2 in the comparative example, Figure 7 b is the temperature distribution cloud diagram of the dust removal system of this application above the pollution source 2. Through this comparison diagram, we can clearly see that Figure 7 In the dust removal system shown in a which is not equipped with the guide assembly plate 3, the temperature distribution at the top of the pollution source 2 is significantly limited by the interference of the lateral airflow, resulting in the heat flow being limited to a small area directly above the pollution source 2, and the heat flow path being biased to the left, making it difficult to effectively climb to the bottom of the dust collecting hood 4, thereby limiting the smooth discharge of the pollutant particles due to the lack of necessary lift. Figure 7 The unique advantages of the dust removal system shown in b are obvious at a glance: the high-temperature gas generated by the heat source forms an orderly suction and climbing flow state in the arc area of ​​the guide combination plate 3 under the ingenious guidance of the guide combination plate 3, and is directly guided to the inside of the dust collecting hood 4. This process not only significantly enhances the lift effect of the airflow, greatly promotes the efficient separation and discharge of polluted dust 9, shortens the dust removal cycle, but also reduces the exhaust volume and speed requirements required by the dust collecting hood 4 by optimizing the airflow path, achieving the dual goals of energy saving and emission reduction and low-noise operation, and demonstrating the excellent performance of the dust removal system of this embodiment in improving dust removal efficiency and reducing energy consumption.

[0062] like Figure 8As shown in a-8e, it is a schematic diagram of the single-way coupling removal effect of pollutant particles in the particle size range of 0.5 to 30μm under the condition of a constant lateral wind speed of 1m / s. It is clearly shown in the figure that under the significant interference of the lateral wind, the same exhaust volume and exhaust speed as those in this embodiment are maintained, and the dust removal system exhibits a weaker capture and discharge ability for pollutant particles in the particle size range of 0.5 to 30μm. In order to achieve a dust removal effect equivalent to that of Example 1, the system parameters must be adjusted. Specifically, to achieve the technical effect of this embodiment, the exhaust volume of the comparative example is greatly increased to at least 5.3m 3 / s, and at the same time, the wind speed at the suction port of the dust collecting hood 4 is increased to no less than 14.7m / s. In addition, the hood opening size of the dust collecting hood 4 needs to be expanded to more than 2.8×2.8m.

[0063] Table 1 Dust removal system parameter comparison table

[0064]

[0065] By comparing the embodiments of the present application with those of the comparative example, under the same air supply conditions, the dust removal system of the present application has the following advantages: (1) When the airflow passes through the guide assembly plate 3, its velocity distribution shows a significant differentiation feature. The airflow velocity in the guide assembly plate 3 area is significantly reduced, while the velocity rises on its left side. This design promotes the vertical upward movement of the polluted dust 9. Compared with the dust removal system of the comparative example, its velocity distribution pattern is more conducive to the efficient discharge of pollutant particles; (2) In the embodiments of the present application, under the combined action of wind pressure and heat pressure, the area between the guide assembly plate 3 and the pollution source 2 naturally forms a significant negative pressure area. Compared with the dust removal system of the comparative example, this negative pressure effect greatly enhances the attraction of the area between the assembly plate of the present application and the pollution source 2, thereby achieving a more excellent dust removal effect; (3) By intuitively comparing the movement trajectory of the dust 9 in the two embodiments, the dust removal system of the present application is comparable to Dust removal efficiency. The dust removal system of the present application only requires a lower exhaust volume (reduced by 56.53% compared to the dust removal system of the comparative example), a slower exhaust speed (reduced by up to 89.11% compared to the dust removal system of the comparative example), and significantly reduces the size of the hood opening of the integrated hood (reduced by 87.2% compared to the dust removal system of the comparative example); (4) The present application achieves a significant reduction in energy consumption and effective control of operating noise, and also greatly saves material costs and installation space. At the same time, under the premise of the same dust removal effect, the energy consumption of the blower that generates the lateral wind 8 is significantly reduced, thereby reducing the operating cost of the enterprise, and the reduction in the operating load of the fan directly reduces noise pollution, providing employees with a comfortable working environment and realizing green production of the enterprise; (5) A method for calculating the curvature of the guide assembly plate 3 is proposed. By adjusting the length of the guide assembly plate 3, connection with dust collecting hoods 4 of different heights is achieved to adapt to different pollution sources 2 and dust collecting hoods 4, which has the advantage of high versatility.

[0066] As an alternative embodiment, the dust collection duct 1 is located at the side of the pollution source 2, and the blower is located at other positions such as above or below the pollution source 2.

[0067] As an alternative embodiment, the power member 303 drives the second guide plate 302 to move along the length direction of the first guide plate 301, that is, the first guide plate 301 is stationary and the second guide plate 302 moves; the power member 303 drives the first guide plate 301 and the second guide plate 302 to move in opposite directions along their own lengths, that is, both the first guide plate 301 and the second guide plate 302 can move.

[0068] As an alternative implementation, the first guide plate 301 and the second guide plate 302 may be slidably connected to each other by rollers, balls or other means.

[0069] As an alternative implementation, the bottom surface of the dust collecting hood 4 is lower than the top surface of the guide assembly plate 3 .

[0070] As an alternative implementation, the power member 303 may also be other devices such as a telescopic servo motor.
