Description

Double-shaft disc sludge drying system

Technical Field

The utility model relates to a drying equipment technical field specifically is a biax disc sludge drying system.

Background

Along with the development of urbanization in China, the yield of urban sewage is continuously increased. In recent years, a large number of municipal sewage treatment plants are newly built for maintaining the municipal water environment and preventing and treating municipal water pollution, so that the problem of municipal sewage pollution is gradually relieved. However, how to treat the sludge in the municipal sewage treatment is a problem to be faced at present, and if the sludge is not properly treated, serious secondary pollution is caused. Therefore, the harmless treatment of the sludge is an urgent need at present.

Sludge generally adopts the desiccator drying process, and traditional sludge drying machine adopts the paddle stirring, because stirring resistance is big, needs powerful motor just can drive, and the cost is than higher, adopts the mode heating of electrical heating moreover, and the energy consumption is also high.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the technical problems of high cost and high energy consumption of the traditional sludge dryer are solved.

The utility model provides a biax disc sludge drying system, include:

the device comprises a cylinder body, a water tank and a water tank, wherein the cylinder body is provided with a wet material inlet, a dry material inlet and a moisture exhaust port;

the two rotating shafts are symmetrically arranged and have opposite rotating directions and are positioned in the cylinder body, and the rotating shafts are hollow and are communicated with the dry material inlet;

the power mechanism drives the rotating shaft;

the plurality of discs are uniformly distributed on the rotating shaft, and the discs are hollow and communicated with the rotating shaft.

Materials enter the cylinder body from the wet material inlet, a heat medium enters the rotating shaft and the disc through the dry material inlet, the heat medium selects saturated steam to heat the rotating shaft and the disc, so that the materials are indirectly heated, and water vapor is discharged from the moisture discharging port to achieve the effect of drying the materials; the rotating resistance of the rotating shaft is reduced due to the arrangement of the rotating disc, so that the power of the motor is reduced, the cost is reduced, the saturated steam indirectly heats the materials, and the energy consumption is saved.

Furthermore, the moisture exhaust port is sequentially connected with a fan, a condenser and a dust remover. The condenser is used for condensing the water vapor, and the dust remover filters the gas at the moisture exhaust port, thereby avoiding environmental pollution.

Furthermore, a plurality of uniformly distributed flow deflectors are arranged in the disc. The guide vanes not only improve the strength of the disc, but also improve the heat exchange effect of the disc.

Furthermore, the outer wall of the cylinder body is provided with a heat insulation layer. The heat preservation is used for barrel heat preservation, improves drying effect.

Furthermore, an air inlet is formed in the upper end of the cylinder body. The air inlet is used for filling dry hot air into the cylinder, so that the saturation of wet air in the cylinder is reduced, and the air discharge is reduced.
