By controlling water content and adding materials, the reduced solid phase can be used to make construction materials, ceramics and other products, so as to achieve the resource utilization.
High solid phase content and large disposal quantity;
High production efficiency, short pro-duction cycle;
Simple production
process ow cost;
High quality;
Meet environmental requirements;
Sintered brick Co-processing Technology
After pretreatment, the solid phase of drilling (drilling cuttings and filter cake) is mixed with shale and fly ash in proportion to make brick. After drying and sintering at high temperature, the brick becomes sintered brick, which can meet the requirements of MU10 grade standard.
NO. | Index | Requirement | ||
1 | Dimensional deviation | ≤2 mm | ||
2 | Appearance quality | No missing edges or corners | ||
3 | Compressive strength | >10 MPa | ||
4 | Weathering resistance | Water absorption<18% Saturation coefficient<0.78 | ||
5 | Heavy metal, petroleum, COD, chroma and pH value in leachate | Meet the sewage comprehensive discharge standard | ||
6 | Internal exposure index and external exposure index | <1 |
The pre-treated solid phase (drill cuttings and filter cake) can be pelleted together with fly ash and other auxiliary materials. And then sintered ceramics can be prepared after drying and sintering. The ceramics can meet the requirements of building materials and environmental protection.
NO. | Index | Requirement | ||
1 | Particle size(mm) | 10~15 | ||
2 | Bulk density(kg/m³) | <800 | ||
3 | Cylindrical compress strength(MPa) | >4.0 | ||
4 | Water absorption(%) | <10 | ||
5 | Softening coefficient | >0.8 | ||
6 | Heavy metal, petroleum, COD, chroma and pH value in leachate | Meet the sewage comprehensive discharge standard | ||
7 | Internal exposure index and external exposure index | <1 |
