Description

Technical Field

[0001] This invention belongs to the technical field of dust removal devices, and particularly relates to a dust treatment device for production workshops. Background Technology

[0002] During the product manufacturing process, a large amount of dust is generated in the production workshop. Inhaling excessive dust can harm human health. Dust reduction and removal in the production workshop has always been a major issue that enterprises need to consider.

[0003] In the prior art, patent document with publication number "CN211987798U" discloses a dust suppression device for coal mining, which actively draws in dust using a fan and uses circulating water for spraying dust suppression. It can continuously spray water mist to improve dust suppression efficiency. A water storage tank is placed at the bottom of a dust suppression box, and the water storage tank and dust suppression box are connected. The width of the water storage tank is smaller than the width of the dust suppression box. An exhaust box is placed on the other side of the dust suppression box, and the exhaust box is connected to the dust suppression box. The height of the exhaust box is smaller than the height of the dust suppression box. One side of the exhaust box is an open structure. The exhaust box, dust suppression box, and water storage tank are integrally formed. An air intake grille is placed on one side of the dust suppression box. Multiple air intake slots are equidistantly opened on the air intake grille, and the air intake slots are connected to the dust suppression box. The bottom of the air intake grille is connected to the water storage tank through two fixing sleeves. A circulating water inlet is opened on one side of the water storage tank, and a filter screen is placed inside the circulating water inlet.

[0004] Existing dust removal devices generally include a water tank for storing water. By drawing airflow containing dust into the water tank, the dust adheres to the water as the airflow flows through the water, causing the dust to settle and thus purifying the airflow. However, because the airflow enters the water tank slowly, the dust settling process in the water is slow, which affects the dust removal effect in the production workshop. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a dust treatment device for production workshops.

[0006] This invention provides a dust treatment device for a production workshop, including a water tank, a duct, and an exhaust pipe. One end of the duct is connected to the water tank, and the other end of the duct serves as an air inlet. One end of the exhaust pipe is connected to the water tank, and the other end of the exhaust pipe serves as an air outlet. The relative height difference between the air outlet and the air inlet is not less than 75% of the height of the production workshop. Condensation pipes are also installed around the exhaust pipe, and both ends of the condensation pipes are connected to a cooling water source.

[0007] An exhaust fan is also installed at the air inlet.

[0008] The dust treatment device in the production workshop also includes a spray pipe, one end of which is connected to the air duct, and the other end of which is connected to the cooling water source.

[0009] The air duct is also fixedly connected to one end of the support rod, and the other end of the support rod is fixedly connected to the air duct cover. The air outlet is located between the air duct and the air duct cover.

[0010] The air duct is also fitted with multiple filter plates, which are arranged at equal intervals along the axial direction of the air duct.

[0011] The number of filter plates is three or more.

[0012] The axial direction of the air duct is consistent with the vertical direction.

[0013] The water tank is also equipped with multiple overflow baffles, which are arranged at equal intervals along the length of the water tank.

[0014] The number of overflow baffles is two or more.

[0015] The water tank is also connected to a drain pipe, which is located close to the air duct.

[0016] The beneficial effects of this invention are as follows: Using the technical solution provided by this invention, since condenser pipes are installed around the exhaust pipe, the airflow passing through the exhaust pipe is cooled by heat exchange with the water in the condenser pipes, resulting in a lower temperature and becoming a cooling airflow. Because the relative height difference between the air outlet and the air inlet is not less than 75% of the height of the production workshop, the cooling airflow returns to the upper space of the production workshop through the air outlet. The airflow inside the production workshop is hot airflow, which has a low density and therefore flows upwards, while the cooling airflow has a high density and therefore flows downwards. This creates a convection effect in the production workshop, increasing the airflow velocity and allowing the hot airflow to enter the water tank more quickly and continuously for purification, accelerating the settling speed of dust carried in the airflow and improving the dust settling effect in the production workshop.

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited thereto; This invention provides a dust treatment device for a production workshop, such as... Figures 1 to 2 As shown, it includes a water tank 1, a duct 2, and an exhaust pipe 3. One end of the duct 2 is connected to the water tank 1, and the other end of the duct 2 serves as an air inlet 4. One end of the exhaust pipe 3 is connected to the water tank 1, and the other end of the exhaust pipe 3 serves as an air outlet 5. The relative height difference between the air outlet 5 and the air inlet 4 is not less than 75% of the height of the production workshop. Condensation pipes 6 are also installed around the exhaust pipe 3, and both ends of the condensation pipes 6 are connected to a cooling water source.

[0020] Using the technical solution provided by this invention, since condenser pipes are installed around the exhaust pipe, the airflow passing through the exhaust pipe is cooled by heat exchange with the water in the condenser pipe, and its temperature decreases, becoming a cooling airflow. Since the relative height difference between the air outlet and the air inlet is not less than 75% of the height of the production workshop, the cooling airflow returns to the upper space of the production workshop through the air outlet. The airflow inside the production workshop is hot airflow. Hot airflow has a low density and therefore flows upward, while cooling airflow has a high density and therefore flows downward. This creates a convection effect in the production workshop, increasing the airflow speed. The hot airflow can enter the water tank more quickly and continuously for purification, accelerating the settling speed of dust carried in the airflow and improving the dust settling effect in the production workshop.

[0021] Specifically, exhaust fans 7 are installed at the four air inlets. This further enables the hot air carrying dust to enter the water tank at a faster speed for settling, thereby improving the dust settling efficiency.

[0022] In addition, the dust treatment device in the production workshop also includes a spray pipe 8. One end of the spray pipe 8 is connected to the air duct 2, and the other end of the spray pipe 8 is connected to the cooling water source. The cooling water sprayed from the spray pipe 8 mixes with the hot airflow carrying dust in a downward direction. The water adheres to the surface of the dust, causing it to settle quickly, which helps to improve the dust settling efficiency.

[0023] In addition, the air duct 2 is fixedly connected to one end of the support rod 9, and the other end of the support rod 9 is fixedly connected to the air duct 10. The air outlet 5 is located between the air duct 2 and the air duct 10. Multiple filter plates 11 are also inserted inside the air duct 2, and the multiple filter plates 11 are arranged at equal intervals along the axial direction of the air duct 2. Preferably, the number of filter plates 11 is three or more.

[0024] Furthermore, the axial direction of the air duct 2 is aligned with the vertical direction. The water tank 1 is also equipped with multiple overflow baffles 12, which are arranged at equal intervals along the length of the water tank 1. There are two or more overflow baffles 12. The water tank 1 is also connected to a drain pipe 13, which is positioned close to the air duct 2.
