The specialized textile printing and dyeing sludge dryer is capable of drying textile printing and dyeing sludge, with low energy consumption and operating costs, achieving automation in textile printing and dyeing sludge treatment.

Process flow of textile printing and dyeing sludge dryer:

The purpose of sludge drying is to remove some moisture from wet sludge to meet different disposal requirements. Drying means that a certain amount of thermal energy is transferred to the moisture content of the material per unit time. These moisture components are heated and vaporized, separated from the material. The material that loses moisture and the vaporized moisture are collected separately. This is the process of drying. Describe this process from the perspective of equipment, including feeding, drying, gas-solid separation, dust capture, wet condensation, solid transportation, and storage. If the properties of the material (viscosity, moisture content, etc.) may cause instability in the drying process (such as adhesion, clumping, etc.), it is necessary to adopt a process of mixing partially dried products with wet materials (return material, dry mud return mixing). At this point, corresponding equipment such as conveying, storage, separation, crushing, screening, lifting, mixing, and feeding should be added before and after solid conveying.

Drying value of textile printing and dyeing sludge:

As an auxiliary fuel for coal combustion, producing lightweight energy-saving bricks, and producing cement pressed products, the harmless, reduced, stabilized, and resourceful treatment of chemical sludge has been achieved.

Characteristics of textile printing and dyeing sludge:

Characteristics and treatment of printing and dyeing sludge: Printing and dyeing sludge contains a large amount of chemical residues, with a high proportion of inherent moisture that is difficult to dehydrate. Its composition is very complex, with high levels of harmful substances and a certain degree of viscosity. It is a difficult problem and has become an urgent social issue that needs to be solved. The proportion of organic components in printing and dyeing sludge is relatively high, and the combustion calorific value of dry sludge is higher than that of general industrial wastewater sludge, with a calorific value of up to 2000 kcal/kg.
