Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, specifically a fresh air dust removal system. Background Technology

[0002] With the rapid development of society, a large amount of particulate dust is generated during the processing and production processes of various industries such as metallurgy, chemicals, power, and building materials. If particulate dust in the working environment is not treated in a timely manner, it will not only harm the health of workers, but also cause serious air pollution when directly discharged into the atmosphere. Based on current stringent environmental protection requirements and the need to protect the personal safety of workers, enterprises must introduce environmental dust removal equipment into their production processes. In existing technologies, environmental protection equipment typically uses pipelines to transport and collect dust. To ensure sufficient airflow within the pipelines to concentrate the dust from the processing unit into the dust removal equipment, high-powered fans are often required. In existing technologies, after the dust-laden air is removed by the dust removal equipment and meets emission standards, the clean air is directly discharged.

[0003] In addition, in production practice, the workplaces where workers operate are often built in a simple manner, mostly workshops formed by steel structure main components, which have poor heat insulation and are often cold in winter and hot in summer, resulting in a poor working environment. Utility Model Content

[0004] This utility model discloses a fresh air dust removal system, which solves the technical problems of simple workshop buildings that are cold in winter and hot in summer in the prior art. It has the technical effects of reasonable structure, improved workplace environment comfort, and improved energy utilization. The technical solution adopted is as follows:

[0005] A fresh air dust removal system includes a dust removal main duct, a fresh air main duct, and a fan assembly. The first end of the dust removal main duct includes several suction branch pipes, and the suction nozzles at the ends of the suction branch pipes are arranged close to the processing unit. The second end of the dust removal main duct is connected to the air inlet of a dust purification device. Under the action of the fan assembly, dust enters the dust purification device through the several suction branch pipes and the dust removal main duct and is filtered out. The air outlet of the dust purification device is connected to the first end of the fresh air main duct, and the second end of the fresh air main duct includes several air outlet pipes extending into the space where the processing unit is located for directional air delivery.

[0006] Based on the above technical solution, a heating module is also included, which is designed to heat the air flowing through the fresh air main duct.

[0007] Based on the above technical solution, the heating module includes several electric heating wires arranged in the main fresh air duct, and the main fresh air duct corresponding to the electric heating wires is covered with a heat insulation layer.

[0008] Based on the above technical solution, a cooling module is also included, which is designed to cool the air flowing through the main fresh air duct.

[0009] Based on the above technical solution, the cooling module includes an outer cylinder fitted outside the main fresh air duct, and a cooling water channel extending spirally around the main fresh air duct is formed inside the outer cylinder. Cooling water can flow through the cooling water channel under the action of an external water pump.

[0010] Based on the above technical solution, the outer cylinder is provided with an insulation layer, and the inlet and outlet of the cooling water channel are respectively connected to the water tank.

[0011] Based on the above technical solution, the air outlet pipe includes a corrugated pipe section at the end to facilitate the arrangement of the outlet section of the corrugated pipe section. The outlet end of the corrugated pipe section is provided with fan blades to ensure uniform airflow.

[0012] Based on the above technical solution, a number of atomizing nozzles are provided in the corrugated pipe section near the outlet end of the corrugated pipe section. The atomizing nozzles are connected to the water source through pipes to spray water mist.

[0013] Based on the above technical solution, the main fresh air duct is also equipped with a solenoid valve to control the opening and closing of the main fresh air duct.

[0014] Beneficial effects

[0015] This utility model has a reasonable structure. The air outlet of the dust purification equipment is connected to the main fresh air duct, and the second end of the main fresh air duct includes several air outlet pipes that extend into the space where the processing unit is located. In this way, clean air can be delivered to the workplace at specific points through several air outlet pipes. On the one hand, the air outlet pipes can blow air and replace the operation of fans for local cooling. On the other hand, they can replace unfiltered external air in circulation, which is conducive to improving the air quality in the workplace. Furthermore, they can improve energy utilization.

[0016] This invention also includes a heating module and a cooling module. The heating module can heat the air flowing through the main fresh air duct, thus heating the air in the workplace and regulating the temperature in cold winters. The cooling module can cool the air flowing through the main fresh air duct, thus cooling the air in the workplace and regulating the temperature in hot summers, further contributing to creating a good working environment.

[0017] In this invention, the outlet end of the air duct is equipped with fan blades, which can avoid direct blowing and avoid causing large airflow disturbances when delivering air at a fixed point, thus helping to create a good working environment. In addition, several atomizing nozzles are also provided at the outlet end to facilitate the adjustment of workplace air humidity and make it easy to use. Attached Figure Description

[0025] like Figure 1 The fresh air dust removal system shown includes a dust removal main duct 1, a fresh air main duct 2, and a fan assembly 8.

[0026] The first end of the main dust removal duct 1 extends into the space where the processing unit 100 is located, such as workshop 200; Figure 1 As shown, the first end of the main dust removal pipe 1 includes several suction branch pipes 11. The end of each suction branch pipe 11 includes a corrugated pipe. The suction nozzle at the end of the corrugated pipe is arranged close to the processing unit 100 to efficiently collect the dust generated during the processing. The second end of the main dust removal pipe 1 extends outside the workshop 200 and is connected to the air inlet of the dust purification equipment 3. Under the action of the fan assembly 8, the main dust removal pipe 1 forms a negative pressure. The dust enters the dust purification equipment 3 through the main dust removal pipe 11 and is filtered out. The dust purification equipment 3 is existing technology and will not be described in detail here.

[0027] In this embodiment, the fan assembly 8 includes several fans electrically connected to the controller. The fans are located inside the housing of the dust purification equipment 3 and provide the wind power for dust to enter the dust purification equipment 3 along the main dust removal pipe 1.

[0028] like Figure 1 As shown, the air outlet of the dust purification equipment 3 is connected to the first end of the main fresh air duct 2, and the second end of the main fresh air duct 2 includes several air outlet pipes 21 extending into the workshop where the processing unit 100 is located. These pipes are used to supply clean air purified by the dust purification equipment 3 into the workshop 200, improving the air quality in the workshop and creating a better working environment. Simultaneously, the air outlet pipes can replace fans for localized cooling. Furthermore, by replacing unfiltered external air in the circulation, the use of filter materials is reduced, costs are lowered, and workplace air quality is improved, especially in situations with high air quality requirements.

[0029] like Figure 1As shown, it also includes a heating module 4, which is designed to heat the air flowing through the main fresh air duct 2. Specifically, the heating module 4 includes several electric heating wires arranged inside the main fresh air duct 2, and the main fresh air duct 2 corresponding to the electric heating wires is covered with an insulation layer. In other embodiments of this utility model, several electric heating wires may also be arranged both inside and outside the main fresh air duct 2. When the weather is cold, an external controller can control the heating module 4 to turn on to heat the air in the workshop and improve the comfort of the working environment.

[0030] In addition, a cooling module 5 is included, which is designed to cool the air flowing through the main fresh air duct 2. Specifically, the cooling module 5 includes an outer cylinder fitted outside the main fresh air duct 2, with an insulation layer covering the outer cylinder. Inside the outer cylinder, a cooling water channel extends spirally around the main fresh air duct. The inlet and outlet of the cooling water channel are respectively connected to a water tank. In this embodiment, a water pump 6 is installed on the pipe connecting the inlet of the cooling water channel and the water tank 7. Cooling water can flow through the cooling water channel under the action of the external water pump 6. To reduce energy consumption, the water tank 7 can be buried underground, utilizing the temperature difference between underground and above ground for cooling. When the weather is hot, an external controller can control the water pump 6 to work, cooling the air in the workshop.

[0031] In this embodiment, the air outlet duct 21 includes a corrugated pipe section at the end to facilitate the arrangement of the outlet section of the corrugated pipe section, thereby achieving fixed-point and directional air delivery, making it more convenient to use. In addition, a fan blade (not shown) is provided at the outlet end of the corrugated pipe section to distribute the air evenly and avoid direct blowing, resulting in a better user experience.

[0032] In addition, a number of atomizing nozzles (not shown) are provided in the corrugated pipe section near the outlet end of the corrugated pipe section. The atomizing nozzles are connected to the water source through pipes to spray water mist. Under the action of airflow, the atomized water is more evenly diffused in the environment to regulate humidity.

[0033] Furthermore, a solenoid valve (not shown) is also installed on the main fresh air duct 2 to control the opening and closing of the main fresh air duct 2. When the dust purification equipment fails to filter effectively, the main fresh air duct 2 can be shut down in time to prevent dust from entering the workshop 200.

[0034] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
