Environment-friendly safety air drying device

[0007] Embodiment 1 of the present invention: a safe and environmentally friendly air drying device, comprising an elongated fan 1, the fan 1 is connected with an air heater 2 and several air curtains 3, and the air heater 2 includes a combustion chamber 4 and Connected to the vent 5 on the combustion chamber 4, the air heater 2 is connected to the air curtain 3 through a hot air duct 6, and a protective cover 7 is provided outside the air heater 2. During operation, the combustion chamber is 4. Heat is generated by combustion, and the heat is transferred from the side wall of the combustion chamber 4 to the air sucked into the air heater 2 from the fan 1. The combustion chamber 4 is also connected to the ventilation port 5, which is used to discharge the exhaust gas produced by the combustion, which is heated by the air in the air heating chamber. 2. The heated air is then sent to the four air curtains 3 through the hot air duct 4. The air curtains 3 are scattered around the warehouse and play the role of circulating air. The protective cover 7 of the air heater peripheral can be placed in artificial contact. Unexpected occurrence of high temperature etc.

[0008] Embodiment 2 of the present invention: a safe and environmentally friendly air drying device, comprising a long fan 1, the fan 1 is connected with an air heater 2 and several air curtains 3, and the air heater 2 includes a combustion chamber 4 and Connected to the vent 5 on the combustion chamber 4, the air heater 2 is connected to the air curtain 3 through a hot air duct 6, and a protective cover 7 is provided outside the air heater 2. The protective cover 7 There are vents on it. During operation, the combustion chamber 4 generates heat through combustion, and the heat is transferred from the side wall of the combustion chamber 4 to the air drawn into the air heater 2 from the fan 1. The combustion chamber 4 is also connected to the ventilation port 5 for discharging the exhaust gas produced by the combustion. , the air heated by the air heating chamber 2 is then transmitted to the four air curtains 3 through the hot air duct 4, and the air curtains 3 are scattered throughout the warehouse and play the role of circulating air. 7. It can be placed in the event of human exposure to high temperature and other accidents.
