Safety protection of Burn Off Oven
1: Secondary water spray
In case of failure of the main water spray system, the secondary water spray system will start automatically. The diameter of the anti blocking nozzle of the secondary water spray system is far larger than that of the primary spray nozzle, and the water quantity of the secondary spray water is 10-20 times of that of the primary spray water.
2: Temperature switch
In case of accident, the primary and secondary water spray fail or fail to work, and the furnace temperature is still rising, the temperature protection system independent of the two temperature control systems will act, disconnect the main burner and spray water. Once it is disconnected, it can not reset automatically, and it needs to press the start button again to continue working.
3: Gravity explosion door
As the pressure in the furnace increases due to accidents, the two gravity explosion-proof doors on the top of the furnace will automatically open in an instant and then close automatically after the pressure is released (pay attention to that no objects that hinder the normal operation of the explosion-proof doors can be placed above the furnace body).
4: Low water pressure protection
When the water pressure is less than 2kg, the heating system will be automatically disconnected and an alarm will be given.
5: Interlock shutdown of combustion engine
Product concept of Burn Off Oven
The Burn Off Oven can efficiently and safely wash the chemicals attached to metal parts such as coating nozzles. High molecular polymer can be cracked and disintegrated when the temperature is higher than 300 ℃ and can be completely oxidized when there is a small amount of air when the temperature is higher than 400 ℃. Firstly, the workpiece with high polymer dirt is heated to 400 ℃ (determined according to the process requirements), so that a large amount of polymer on the workpiece flows into the collection container at the lower part of the furnace after melting, and then the furnace temperature is raised to 400 ℃ and a small amount of air is injected Fresh air can fully oxidize the remaining polymer, and the generated carbon dioxide will be pumped out of the furnace together with water after water spraying.
Product characteristics of Burn Off Oven
1. The treatment of heat cleaning furnace is beyond the traditional incineration and chemical methods, which bring about high cost, toxicity, injury to operators, large deformation of workpiece and environmental pollution. The use of Burn Off Oven not only has low cost, small labor intensity and small deformation, but also is safe, non-toxic and pollution-free.
2. The operation is simple, and the whole process can be completed by pressing the start button without special training for operators.
3. Reduce energy consumption (50% of similar products), no special requirements on the number, shape and size of the workpiece, which can ensure no deformation of the workpiece.
4. The sealing design ensures the sealing performance.
5. Aluminum silicate fiber is used as the main insulation material to ensure good thermal insulation performance and service life.
6. The combustor and main control elements are all imported parts.
7. Equipped with PLC and solid state relay.
8. Advanced smoke control methods, emissions meet the standards, GB 16297-96 and gwpb3-99.
9. There are five levels of security protection system.
