1. The production efficiency of purification in the inferior furnace is low. The traditional production process takes 25 days to 30 days to produce one furnace, which leads to low productivity.
2. The purification pollution is serious. The traditional graphitization furnace is not airtight, and the accessory insulation material will produce a large amount of carbon monoxide, sulfur dioxide, hydrogen sulfide, heavy metals and other high-polluting substances.
3. Purification and high energy consumption. According to the current production process, the power consumption per T of finished products is about 12000 kilowatt-hours.
4. The three-acid method is highly polluting. The three-acid chemical method for purifying water is very polluting, and also produces a lot of solid waste.
5. The purity of triacid is not high. 99.95-99.99 percent purity.
6. The three-acid method has poor homogeneity. The reaction is unstable due to the change of acid composition and PH value.
Solution:
1. The energy consumption of automatic continuous vacuum atmosphere furnace is reduced by half, about 40%.
2. Green production and environmental protection: fully sealed negative pressure use, tail gas (carbon fiber and other materials used as thermal insulation medium containing sulfur dioxide and other substances are almost nonexistent) and heat are convenient for centralized recovery, easy to handle, environmental protection is pressureless, environmental protection investment is small, tail gas and heat can be recycled as resources, which is a major equipment encouraged by national policies.
3. High production efficiency, working continuously for 24 hours.
4. Good graphitization homogeneity and stable product quality.
5. Small investment.
6. Low production cost.
7. Labor protection: almost no dust, low protection level.
8. Low labor intensity (once per hour), automatic loading and unloading of powder.
9. It covers a small area and is light assets as a whole.
