Structure characteristics of boiler flue gas sludge drying equipment

The boiler flue gas sludge drying equipment with boiler flue gas as heat source reuses the waste heat energy of the enterprise and has the characteristics of energy saving and consumption reduction. So, what are the differences between boiler flue gas sludge drying equipment and ordinary sludge drying equipment in structure?

Characteristics of boiler flue gas sludge drying equipment

The complete set of boiler flue gas sludge drying equipment is mainly composed of heat source device, feeding and discharging device, drying equipment, dust removal equipment and control system. The drying equipment includes material guiding area, lifting area, deep drying area and discharging area.

1. Combined lifting device

In the whole drying process, the properties of materials will change constantly. The combined lifting plate can continuously scatter and fill the whole drying chamber with scattered sludge particles, forming a uniform material curtain, increasing the contact area between sludge particles and hot air, and accelerating heat and mass transfer. For the drying of materials with high wet viscosity, an anti sticking device is set to prevent the sludge from sticking to the dead corner of the cylinder wall and blocking.

2. New supporting wheel and tyre device

The new type of supporting wheel device, the contact surface between the supporting wheel and the wheel band is more uniform and wide, and the running resistance is small, which ensures the service life of the supporting wheel pulley belt is longer, and the stability of the cylinder body in the process of running is increased.

3. Dust collecting device of tail cover

The tail cover of boiler flue gas sludge drying equipment can change the direction of tail gas, and has the effect of preliminary dust collection, which can reduce certain pressure for subsequent tail gas dust collection treatment.

4. Front and rear sealing structure

In front of and behind the main body of the boiler flue gas sludge drying equipment, the two ends of the cylinder are designed with sealing devices to strengthen the sealing and thermal insulation performance of the cylinder, and the installation and maintenance are convenient.
