Sludge is the industrial waste generated during the production process of municipal sewage processing. Because sludge has many disadvantages such as high moisture content, high viscosity, high water holding capacity, and low calorific value. It is difficult to achieve industrial utilization. Jiutian operated a series of technical researches on the current market situation of sludge treatment and the characteristics of sludge in various regions. Jiutian Company concentrating created a new generation of sludge rotary drum drying system, drying product moisture can be reduced less than 25%, it totals achieved the standard of sludge landfill and further incineration processing conditions. The technology of equipment gets absolutely mature enough, also it has a stable capacity for operation and very convenient to operate and maintain.
The working principle of the sludge drying equipment as following: About 80% of the moisture content for the wet sludge has stickness. Before the drying process, it first enters three roller belt-dewatering machines, and the sludge moisture removed to 55-60%.
After entering the rotary drum dryer and drying, the wet sludge enters the tumble dryer and spitting into following six drying work areas:
The first is the material feedstock zone. The wet mud enters this zone and contacts the high temperature hot air to rapidly evaporate moisture. The material is in a large lifting flight angle. Under the lifting flight drop and pick up, it will be introduced into the next working area without forming a bond.
Second, the clean up area will repeatedly break and beat the material. In this area, the equipment is designed to break and beat all of the material by the cleaning device, and the wet mud is picked up and beaten by the grating copy board.After a large amount of wet mud is repeatedly crushed and beaten, it is broken and kneaded into 20-40mm pellets of coal slime to form the state of the material curtain, increasing the heat exchange area, increasing the drying rate, and the cleaning device reasonably cleans the mud adhered to the inner wall and prevent the wet mud from sticking.
Thirdly, in the main drying zone, the wet mud that has been conducted in the second zone has been in a state of loose granularity. The material is picked up by the radial slanting flight on cascade uniformity, and it conducted full heat exchange with the hot air.
Fourthly, It is beaten and broken Drying zone, where the mud is repeatedly beaten and broken, the mud particles are broken from 20-40mm to 10-20mm (customer requirements granularity), the moisture is further reduced;
Fifth, the enhanced drying zone, the broken small granular mud is dense in the area from the copy board which is lifted to fully absorb the heat of the hot air and discharge the moisture to get the water requirement and prepare the material for discharge.
The sixth is the outlet material. To prevent the discharge of dust, the rotary drum did not provided with lifting flight in this area, and the material is rolled and glided to the discharge opening. The moisture of Sludge dropped to about 20-25% to dryer out, and finally complete the whole drying process.
Jiutian Sludge Drum Dryer is mainly composed of hot air furnace, scattering feeder, belt conveyor, rotary drum dryer, belt outlet conveyor, draught fan, dust collector, deodorant device and electric cabinet.
Features and advantages:
1. The heat source can be low cost steam, biomass, natural gas, coal, etc.
2. Simple and digital control panel for easy operation and maintenance
3. Sludge weight will reduce by approximately 60%, the volume of sludge will reduce by 4-5 times.
4. Due to weight and volume reduction, the transportation cost of sludge will reduce significantly.
5. Reduction in moisture content, the calorific value of sludge increases.
6. High drying temperature will sterilize and deodorize the sludge.
Widely used in various types of sludge drying, such as electroplating sludge, tannery sludge, chemical sludge, oil field sludge, municipal sewage treatment plant sludge, activated sludge, sewer sludge, petrochemical sludge, paper sludge, printing and dyeing sludge, biological fermentation bacteria residue and drying other high-humidity materials such as various kinds of dregs.
Below is a comparison of various sludge before and after drying:
| Model | Capacity(t/h) | Evaporation Moisture Capacity(t/h) | Moisture Content of Raw Material(%) | Drop Moisture Content(%) | Drying Temperature (ºC) | Power(kw) | Total Weight (kg) | Spatial Footprint(m²) |
