How can a hot air circulation oven avoid an explosion? This is a good question. In fact, from the structural design of the hot air circulation oven, it is generally not explosive. Because the interior of the hot air circulation oven is always ventilated from the outside, the air blowing device continuously circulates the air inside and outside the oven. As we all know, the cause of the explosion is that a large amount of gas is generated in a certain space in a short time. Therefore, according to the design principle of the hot air circulation oven, it is difficult to explode by itself.
However, industrial production pays attention to safety. There is a slight possibility that we must pay attention to it and we must eliminate it and truly realize safe production.
For some flammable and explosive materials, we still need to pay attention. There is no special requirement. We do not recommend using hot air circulation oven to dry flammable and explosive materials. Although the design of hot air circulation oven can avoid explosion by exhausting air, if it encounters flammable and explosive materials with extremely fast volatilization reaction rate. Ordinary exhaust is still useless. If it is necessary to dry it, we recommend that the physicochemical properties need to be evaluated first, within the allowable range.
For general materials, although the possibility of explosion is extremely low, in actual use, we still recommend the following operation requirements:
1. No other things can be placed on the bottom plate of the studio. The materials in the studio cannot be filled up, and the air duct must be left between the materials.
2. Start the exhaust system first, then put in the material and then start the heating system.
3. If the material will generate gas during the heating process, increase the exhaust and pump the gas directly out of the oven.
4. Carefully monitor the temperature rise process of the temperature control instrument. If there is a sudden situation, please cut off the heating device for the first time.
The above is the details of how to avoid the explosion of the hot air circulation oven for your reference. Although the hot air circulation oven is an extremely safe drying equipment, we should still operate as required during the use process to achieve true safe production.
