Technical Field

[0001] The invention relates to the technical field of dust removal, and in particular to a dust removal device. Background Art

[0002] With the ever-increasing demand for clean energy, photovoltaic technology continues to develop and be applied. Glass has the advantages of high light transmittance, low reflectivity, and high pressure resistance, and is widely used in the field of photovoltaic materials. The wide application of glass has promoted the development and popularization of various glass processing technologies. Laser cutting has become the preferred method for glass drilling. The emission and treatment of glass dust generated after cutting affects the workshop environment and the health of employees.

[0003] In the deep processing and drilling process of solar glass, a large amount of glass dust is generated during the laser cutting of glass. The dust is sucked into the container by the dust extractor, and the gas is directly discharged after being filtered by the dust filter element. The discharged gas still contains a large amount of glass dust that has not been filtered clean, causing the workshop air to be filled with dust that is invisible to the naked eye, thereby causing dust particles to continuously deposit and adhere to the electronic components of the equipment and the mechanical transmission structure containing oil, affecting the electrical and mechanical properties of the equipment, especially adhering to the internal laser lens, causing light and particles to react on the surface of the lens, resulting in a series of problems such as wear and aging, laser power attenuation, etc., and long-term accumulation has caused production instability and uncertainty of equipment failure, and most importantly, it has brought great harm to the health of employees.

[0027] In the deep processing and drilling process of solar glass, a large amount of glass dust is generated during the laser cutting of glass. The dust is sucked into the container by the dust extractor, and the gas is directly discharged after being filtered by the dust filter element. The discharged gas still contains a large amount of glass dust that has not been filtered clean, causing the workshop air to be filled with dust that is invisible to the naked eye, thereby causing dust particles to continuously deposit and adhere to the electronic components of the equipment and the mechanical transmission structure containing oil, affecting the electrical and mechanical properties of the equipment, especially adhering to the internal laser lens, causing light and particles to react on the surface of the lens, resulting in a series of problems such as wear and aging, laser power attenuation, etc., and long-term accumulation has caused production instability and uncertainty of equipment failure, and most importantly, it has brought great harm to the health of employees. The dust extractor in the prior art has a single structure and poor filtering effect. The gas discharged after filtering still contains a large amount of glass dust, and the energy consumption of installing a traditional dust collector on the basis of the dust extractor is high, and the dust removal effect cannot be guaranteed. Therefore, how to improve the purification and filtering effect at a low cost is a technical problem that needs to be solved urgently by technicians in this field.

[0028] See also Figure 1 and Figure 2 In order to solve the above problems, the embodiment of the present application provides a dust removal device 10, a dust removal device 10, including a first bin body 20, a second bin body 30 and a third bin body 40, the first bin body 20 and the second bin body 30 are connected through a first through hole 51, the second bin body 30 and the third bin body 40 are connected through a second through hole 52, an air inlet 53 is opened in the first bin body 20, and an air outlet 54 is opened in the third bin body 40; a first liquid cavity 21 is formed at the bottom of the first bin body 20, a first guide plate 22 is provided above the first liquid cavity 21 in the first bin body 20, and the first guide plate 22 is provided above the first liquid cavity 21. 2 is blocked between the air inlet 53 and the first through hole 51, and the first guide plate 22 extends toward the first liquid chamber 21; the second chamber body 30 is provided with a first filter 31, and the first filter 31 is located between the first through hole 51 and the second through hole 52; the third chamber body 40 has a third liquid chamber 41 formed at the bottom, and the third guide plate 42 and the second filter 43 are provided above the third liquid chamber 41 in the third chamber body 40, the third guide plate 42 is blocked between the second through hole 52 and the air outlet 54, and the third guide plate 42 extends toward the third liquid chamber 41, and the second filter 43 is provided in front of the air outlet 54.

[0029] The dust removal device 10 includes a first bin 20, a second bin 30 and a third bin 40. The second bin 30 and the third bin 40 can be provided in two pieces respectively. The two second bins 30 are respectively located on both sides of the first bin 20, and the two third bins 40 are respectively located on the side of the second bin 30 away from the first bin 20. The first bin 20 is a purification main bin, the second bin 30 is a filtration sub-bin, and the third bin 40 is a filtration sub-bin. The first bin 20, the second bin 30 and the third bin 40 are interconnected. Specifically, the first bin 20 and the second bin 30 are connected through a first through hole 51, and the first through hole 51 is used to allow the gas filtered in the first bin 20 to flow out to the second bin 30. The second bin 30 and the third bin 40 are connected through a second through hole 52, and the second through hole 52 is used to guide the gas filtered in the second bin 30 to enter the third bin 40. An air inlet 53 is provided in the first warehouse body 20, and an air outlet 54 is provided in the third warehouse body 40. The air inlet 53 is used for the gas containing glass dust to flow into the dust removal device 10, and the air outlet 54 is used for the filtered gas to flow out of the dust removal device 10. When the dust removal device 10 is used, the gas containing glass dust enters the first warehouse body 20 through the air inlet 53, and after being filtered in the first warehouse body 20, the gas flows out to the second warehouse body 30 through the first through hole 51. Further, after being filtered in the second warehouse body 30, the gas flows out to the third warehouse body 40 through the second through hole 52, and the gas flows out of the dust removal device 10 through the air outlet 54 after being filtered in the third warehouse body 40.

[0030] See also Figure 1 The first liquid chamber 21 is formed at the bottom of the first chamber 20, and the first liquid chamber 21 is provided with filtered liquid. For example, a certain amount of water can be placed in the first liquid chamber 21. In the height direction, the distance between the bottom end of the first guide plate 22 and the filtered liquid is 1 cm to 5 cm, and the distance between the bottom end of the first guide plate 22 and the baffle plate 23 is 6 cm to 10 cm. For example, the distance between the bottom end of the first guide plate 22 and the filtered liquid is 1 cm, and the distance between the bottom end of the first guide plate 22 and the baffle plate 23 is 6 cm. A first guide plate 22 is provided above the first liquid chamber 21 in the first chamber body 20. The first guide plate 22 blocks the air inlet 53 and the first through hole 51, and extends toward the first liquid chamber 21. The first guide plate 22 is a baffle with a certain curvature. The first guide plate 22 can be divided into an upper guide plate and a lower guide plate. The upper guide plate is connected to the lower guide plate, and both are baffles with a certain curvature. The upper guide plate is used to guide the airflow to move in a specified direction, and the lower guide plate is used to guide the direction of the airflow to collide with water and increase the contact area between the airflow and the water.

[0031] See also Figure 1 and Figure 2, a first filter 31 is provided in the second chamber 30, and the first filter 31 is located between the first through hole 51 and the second through hole 52. The first filter 31 is used to intercept dust in the airflow. Specifically, the first filter 31 can be made of synthetic fiber filter cotton. The bottom of the third chamber 40 forms a third liquid chamber 41. A third guide plate 42 and a second filter 43 are provided above the third liquid chamber 41 in the third chamber 40. The second filter 43 is provided in front of the air outlet 54. The second filter 43 is used to filter glass dust particles in the gas. The second filter 43 can be made of polypropylene or other composite materials. The third guide plate 42 is blocked between the second through hole 52 and the air outlet 54, and the third guide plate 42 extends toward the third liquid chamber 41. The guide plate is a baffle with a certain curvature. The guide plate can be used to change the direction of the airflow and guide the airflow to collide with water. In some embodiments, the distance between the guide plate and the pool can be set to 5 cm.

[0032] The airflow containing glass dust flows into the first warehouse body 20 from the air inlet 53, flows to the lower guide plate through the upper guide plate of the first warehouse body 20, and collides with the liquid in the first liquid chamber 21. Further, the airflow flows through the gap between the lower guide plate and the liquid in the first liquid chamber 21, moves upward to the first through hole 51, flows to the second warehouse body 30, moves downward through the first filter element 31, changes the movement direction at the end of the second warehouse body 30, passes through the first filter element 31 upward again, and then flows into the third warehouse body 40 from the second through hole 52. After passing through the third guide plate 42, the movement direction is changed to move downward and collide with the liquid in the third liquid chamber 41, and flows out through the gap between the third guide plate 42 and the third liquid chamber 41, passes through the second filter element 43, and finally completes the filtration and purification and is discharged along the airflow outlet 54 of the third warehouse body 40, realizing a one-time purification process. In the above process, the energy consumption is extremely low, and physical dust removal is performed in a manner close to zero energy consumption. Through the multiple filtering design, the purification and filtering effect can be effectively improved, the discharge of harmful gases can be prevented, and the production and operation costs can be reduced.

[0033] A baffle 23 is provided between the first liquid chamber 21 and the first through hole 51 in the first chamber 20. The baffle 23 extends to the top of the first guide plate 22. The baffle 23 can be a baffle with a certain curvature, which is used to hinder the upward movement of airflow and water flow and change the direction of the airflow. Specifically, the air flows through the gap between the lower guide plate and the liquid in the first liquid chamber 21, and changes direction after being blocked by the baffle 23, and moves upward to the first through hole 51. In some embodiments, the distance between the baffle 23 and the lower guide plate can be set to 10 cm. An air passage 60 is formed between the baffle 23 and the first guide plate 22, and the airflow can flow upward through the air passage 60, and then flow into the second chamber 30 from the first through hole 51 in the first chamber 20.

[0034] The air inlet 53 is opened at the top of the first warehouse body 20, and the gas containing glass dust flows into the first warehouse body 20 through the air inlet 53. One end of the first guide plate 22 is connected to the top of the first warehouse body 20, and the other end extends obliquely toward the bottom and side wall of the first warehouse body 20. The gas containing glass dust can move along the lower side of the first guide plate 22 to the bottom of the first guide plate 22. The bottom of the first guide plate 22 extends toward the first liquid cavity 21. A certain amount of water can be placed in the first liquid cavity 21. The airflow can contact the liquid in the first liquid cavity 21 through the bottom of the first guide plate 22, so that some glass dust is retained in the first liquid cavity 21 through the contact between the airflow and the liquid, thereby achieving a certain purification effect, which can effectively improve the purification and filtration effect. Furthermore, one end of the baffle plate 23 is connected to the side wall of the first chamber 20, and the other end extends to the top of the first guide plate 22. Due to the structural positional relationship between the baffle plate 23 and the first guide plate 22, the airflow can flow into the air passage 60 under the guidance of the baffle plate 23, and then move upward along the air passage 60. The first guide plate 22 is an arc-shaped plate structure protruding toward the air inlet 53, so that the airflow is guided more smoothly. The baffle plate 23 is an arc-shaped plate structure protruding toward the first through hole 51, and the third guide plate 42 is an arc-shaped plate structure protruding toward the air outlet 54. The arc-shaped plate structure can generate multiple rotation centers after the gas passes through the baffle, which can reduce energy consumption while guiding.

[0035] The distance between the bottom end of the first guide plate 22 and the first liquid chamber 21 is smaller than the distance between the bottom end of the first guide plate 22 and the baffle plate 23. The bottom end of the first guide plate 22 is closer to the liquid surface in the first liquid chamber 21 than the baffle plate 23, so as to ensure that after the air flow contacts the liquid in the first liquid chamber 21 through the bottom end of the first guide plate 22, it moves upward under the guidance of the baffle plate 23. At this time, the distance between the bottom end of the first guide plate 22 and the liquid surface in the first liquid chamber 21 is the pressure difference distance. The airflow volume can be smaller than the exhaust gas inlet airflow volume, thereby forming an airflow pressure difference inside and outside the first guide plate 22. The pressure inside the first guide plate 22 is greater than that outside. The airflow hits the first liquid chamber 21 downward, causing splashes on the water surface. The airflow carries water molecules toward the baffle plate 23. After being blocked by the baffle plate 23, the water molecules fall back into the pool due to the superposition of the movement direction and gravity inertia. The dust particles are adsorbed by the water molecules and sink to the bottom of the pool together, effectively improving the purification and filtration effect and preventing the discharge of harmful gases.

[0036] The first through hole 51 is located at the top of the side wall of the first warehouse body 20, and the second through hole 52 is located at the top of the side wall of the third warehouse body 40. An isolation plate 32 is provided in the second warehouse body 30 between the first through hole 51 and the second through hole 52. The isolation plate 32 is used to separate the two air flow inlets of the first warehouse body 20 and the third warehouse body 40, and change the direction of air flow movement so that the air flow moves from top to bottom. The isolation plate 32 forms a zigzag air duct 33 in the second warehouse body 30 to connect the first through hole 51 and the second through hole 52, and the first filter element 31 is arranged in the zigzag air duct 33. Specifically, after the airflow flows into the second warehouse body 30 from the first through hole 51, it moves downward through the first filter element 31 after being blocked by the isolation plate 32. After changing the direction of movement at the bottom of the second warehouse body 30 and passing through the first filter element 31 again upward, it flows into the third warehouse body 40 from the second through hole 52. That is, the airflow can first move downward and then move upward in the zigzag air duct 33. In this process, the airflow can pass through the first filter element 31 once when moving downward, and pass through the first filter element 31 again after moving upward, thereby achieving sufficient purification of the gas and improving the purification effect of the exhaust gas.

[0037] The second filter element 43 is connected between the third guide plate 42 and the side wall of the third warehouse body 40. The second filter element 43 is used to filter glass dust particles in the gas. The second filter element 43 covers the gas flow space between the third liquid cavity 41 and the air outlet 54. The gas flowing into the third warehouse body 40 from the second through hole 52 changes its direction of movement downward after passing through the third guide plate 42 and collides with the liquid in the third liquid cavity 41, and flows out through the gap between the third guide plate 42 and the third liquid cavity 41, passes through the second filter element 43, and finally completes the filtration and purification and is discharged along the air outlet 54 of the third warehouse body 40. A spray head 24 is provided in the first warehouse body 20, and the spray head 24 is arranged between the first guide plate 22 and the first through hole 51. The spray head 24 is used for spraying water mist. A first row of dust accumulation ports 25 and a first drain port 26 are provided in the first liquid chamber 21. A third row of dust accumulation ports 44 and a third drain port 45 are provided in the third liquid chamber 41. The first row of dust accumulation ports 25 is used for cleaning the glass powder accumulated in the first liquid chamber 21, and the third row of dust accumulation ports 44 is used for cleaning the glass powder accumulated in the third liquid chamber 41. The first drain port 26 is used for replacing the water in the first liquid chamber 21, and the third drain port 45 is used for replacing the water in the third liquid chamber 41.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
