Embodiment 1
[0034] The preparation method of the cyanobacteria solid briquette fuel of the present embodiment, comprises the following steps:
[0035] 1. Drying: Dry the blue-green algae to reduce the water content of the blue-green algae to 10%.
[0036] 2. Crush: crush and sieve the cyanobacteria to obtain the cyanobacteria raw material, and the particle size of the cyanobacteria raw material is ≤5mm.
[0037] 3. Add denitrification and antifungal agents: add calcium propionate according to 8% of the mass of blue-green algae raw materials, and stir evenly to obtain dried blue-green algae raw materials.
[0038] 4. Molding: Under the conditions of molding pressure of 60MPa and molding temperature of 80°C, the dried cyanobacteria raw material is mechanically extruded by a molding machine to become a solid fuel.
[0039] 5. Cooling: Sieve out the unformed fines of the high-temperature solid fuel on a vibrating sieve, and use it to lower the temperature to below 10°C higher than room tempe...
