Description

Technical Field

[0001] This utility model relates to the field of air curtain system technology, specifically to an air curtain system with a high safety factor suitable for hazardous waste temporary storage warehouses. Background Technology

[0002] A conventional air curtain system, also known as an air curtain machine, is an air purification device that uses a high-speed motor to drive a cross-flow or centrifugal fan to generate a powerful airflow, forming an "invisible curtain." This type of system is widely used in various places such as shopping malls, theaters, hotels, restaurants, conference halls, homes, and schools, but it is mostly unsuitable for industrial settings.

[0003] Hazardous waste storage warehouses are specific spaces designed for the safe and orderly storage of hazardous waste. They primarily store the following types of waste:

[0004] Toxic waste includes liquid, solid, or semi-solid substances containing toxic chemicals that may pose a threat to the environment and human health.

[0005] Flammable waste: such as flammable liquids, flammable solids, and substances that spontaneously combust upon contact with water. These substances can easily cause fires or explosions under certain conditions.

[0006] Explosive waste: refers to waste that can undergo violent chemical reactions under external influences (such as heating, impact, etc.), instantly generating a large amount of gas and heat, and is therefore explosive.

[0007] Organic matter and organic peroxides: These types of wastes may cause combustion or explosion under certain conditions and require special care to handle.

[0008] Industrial waste containing heavy metals, such as waste lead and waste aluminum, can pollute soil and water bodies if not properly treated.

[0009] Used batteries: This includes all types of batteries, such as lead-acid batteries and nickel-cadmium batteries, which contain heavy metals and other harmful substances.

[0010] Waste oil: such as waste engine oil, waste lubricating oil, etc. If these wastes are discharged indiscriminately, they will cause environmental pollution.

[0011] Other wastes with hazardous properties such as corrosiveness, toxicity, and infectiousness include: waste acid, waste alkali, scrapped or expired medicines, raw and auxiliary materials, broken fluorescent tubes, energy-saving lamps, and printing consumables.

[0012] In summary, hazardous waste temporary storage warehouses store a wide variety of wastes, including chemical waste, radioactive waste, medical waste, and other wastes with hazardous characteristics. These wastes require special care during storage to ensure they do not pose a threat to the environment or human health.

[0013] Currently, hazardous waste temporary storage warehouses all use conventional air curtain machines. This can cause safety hazards caused by the electrical equipment of the air curtain machine itself. Under long-term working conditions, the efficiency of the motor will decrease. In addition, the environment of the hazardous waste temporary storage warehouse is complex, which affects the service life of the air curtain machine, increases maintenance and operating costs, and wastes labor.

[0014] When a conventional air curtain system is operating normally, because the equipment is installed entirely inside the hazardous waste storage warehouse, there is a high risk of combustion or explosion if the equipment ages and leaks electricity, posing a significant safety hazard to personnel. Furthermore, the complex composition of exhaust gases within the hazardous waste storage warehouse is highly corrosive to the air curtain machine, leading to a shortened lifespan, high failure rate, and increased operating costs. The air curtain machine's outlets also require regular cleaning and replacement, further increasing maintenance costs.

[0015] Based on these circumstances, a high-safety-factor air curtain system suitable for hazardous waste temporary storage warehouses is hereby invented. Utility Model Content

[0016] In response to the problems in related technologies, this utility model proposes an air curtain system with a high safety factor suitable for hazardous waste temporary storage warehouses, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0017] Therefore, the specific technical solution adopted by this utility model is as follows:

[0018] A high-safety-factor air curtain system suitable for hazardous waste temporary storage warehouses includes a box-type centrifugal fan. A main air duct is installed on the upper outer side of the box-type centrifugal fan. An air volume regulating valve is installed at the bottom of the main air duct. A top air outlet duct is installed at the bottom of the air volume regulating valve. Side air outlet ducts are installed at both ends of the top air outlet duct. Air outlets are provided on the inner sides of both the top air outlet duct and the side air outlet ducts.

[0019] As a further embodiment of this utility model, a warehouse is provided on the outside of the main air duct, and the box-type centrifugal fan is located on the outside of the warehouse.

[0020] As a further embodiment of this utility model, the warehouse has a doorway on its inner side, and both the top air outlet pipe and the side air outlet pipe are located inside the doorway.

[0021] As a further embodiment of this utility model, the top air outlet pipe and the side air outlet pipe are arranged in a U-shape.

[0022] As a further embodiment of this utility model, an inner baffle is provided on the inner side of the air outlet, an outer baffle is provided on the outer side of the air outlet, and a sealing plate is installed on the air outlet.

[0023] As a further embodiment of this invention, the length of the outer baffle is greater than the length of the inner baffle.

[0024] The beneficial effects of this utility model are as follows:

[0025] This air curtain system consists of a box-type centrifugal fan, ductwork, and air outlets. The box-type centrifugal fan is installed outside the hazardous waste temporary storage warehouse and connected to the warehouse entrance via the main duct. Air outlets are installed on both sides and top of the warehouse door using branch pipes. Air volume regulating valves are installed at the junctions of the branch pipes and the main pipe to adjust the airflow. The box-type centrifugal fan is controlled from outside the warehouse. When the fan is running, airflow exits from both sides and top of the warehouse air outlets, forming an air curtain at the entire warehouse entrance. Airflow is concentrated at the warehouse entrance, preventing the escape of waste gas from inside the warehouse. The air outlets of the branch pipes consist of an outer baffle, an inner baffle, intermittent air outlets, and intermittent seals. The outer baffle is longer than the inner baffle, serving to control the direction and guide the airflow, preventing air leakage and thus reducing the effectiveness of the air curtain. Regularly cut air outlets are created between the inner and outer baffles using laser cutting. The length of the air outlets and the length of the seals are designed to control the air velocity and volume when the box-type centrifugal fan is running, achieving the purpose of forming an air curtain. External power equipment reduces the risk factor inside the hazardous waste temporary storage warehouse and protects the personal safety of staff; the power equipment does not come into direct contact with the exhaust gas inside the hazardous waste temporary storage warehouse, extending the service life of the equipment and reducing maintenance costs; the air curtain system is simple and easy to operate after commissioning, reducing operating costs; it provides optimization and transformation ideas for air curtain systems in related and similar industries and helps their future development.
