Rotary sludge drying machine principle and characteristics
Spindle Sludge Dryer Its principle: When the water containing sludge (75-85%) enters the machine body from the reel conveyor, the viscous sludge is fed into the flat carousel by the quantitative conveying device, and the high temperature generated by the water-containing sludge enters the turntable after the burner With the gas injection, in order to avoid excessive damage to the organic temperature of the furnace, a fan is provided to regulate the furnace temperature, and the rotation speed of the turntable is controlled by a decelerator. The water content and drying time of the sludge can be arbitrarily adjusted to ensure the moisture content of the discharged dry sludge. At 10-40%. The pathogenic microorganisms and parasite eggs present in the sludge are provided with a microwave generator in the lower part of the dryer. Because the microwave frequency is 2450 MHz, billions of collisions occur per second, thereby achieving sterilization and loosening effects. Due to the toughness of the surface of the sludge, the tumbler is placed in the dryer, and it is forced to roll over, forcing the water-containing sludge to dry within the prescribed time. During the drying process, the sludge will generate malodorous gases. Inject ozone into the tail of the turntable to remove odors.

The main features of rotary sludge drying machine are:
1). Equipment cost is low, operating costs are saved, and automation is high.
2). Rotary drying technology is to use its circumference to expand the grate area. It has a large radiation area, high heat transfer efficiency, and long sludge retention time.
3). The coal-fired (oil) burner is arranged on the rotary table dryer. It has strong adaptability and high thermal efficiency. The temperature of the furnace can be adjusted, which is beneficial to the destruction of organic materials and improves the utilization rate of dry mud.
4). The microwave heating is even and it is especially effective for the decomposition of insoluble substances in the sludge. With microwave heating for only 30 minutes, the sludge can be dried and decomposed, which is 20-40 times faster than conventional heating. It has strong penetrating ability, and it is easy to be broken after drying, and it also has the effect of sterilization.
5). With an ozone generator, ozone is a very strong oxidant and highly efficient disinfectant. Its oxidation capacity is second only to fluorine, ranking second. Deodorant, deodorant, disinfection special features to remove harmful gases.
6). The appearance is beautiful, the structure is reasonable, the reliability is strong, the totally enclosed structure, the service life of the equipment, and the maintenance are convenient.
