Abstract

The invention discloses a sludge fragmentation-type drying device. The sludge fragmentation-type drying device comprises a transverse drying main cylinder, a frame for positioning the drying main cylinder and a rotor main shaft. One end of the drying main cylinder is provided with a feeding end and the other end is provided with a discharge end. The drying main cylinder can rotate relatively to the feeding end and the discharge end. The top of the feeding end is provided with a heat flue gas inlet and the top of the discharge end is provided with a wet flue gas outlet. The rotor main shaft is arranged in the drying main cylinder. The frame is provided with a bearing pedestal for positioning the rotor main shaft. The frame is provided with a main shaft driving motor for driving the rotor main shaft to rotate and a main cylinder driving motor for driving the drying main cylinder to rotate. Rotation directions of the rotor main shaft and the drying main cylinder are opposite. The rotor main shaft is provided with multiple stirring pushing rods. The sludge fragmentation-type drying device can effectively dry high-water content sludge, has a continuous and stable drying process, has high drying efficiency, has high integral drying uniformity and has good drying effects.

Description

technical field

[0001] The invention belongs to the technical field of sludge treatment, in particular to a sludge crushing type drying equipment. Background technique

[0002] A large amount of sludge will be produced in the process of sewage treatment, and the treatment method of these sludges is usually incinerated in a furnace, and the hot flue gas discharged after incineration is about 300 to 400 degrees. Since the initial moisture content of the sludge is about 75% to 85%, the water content is too high to be incinerated. Therefore, before the sludge incineration, the sludge needs to be dried first. After the treatment, the moisture content is greatly reduced. , and then the incineration operation can be carried out. Although the current sludge drying treatment methods can achieve a certain degree of dehydration and drying, there are still many deficiencies in terms of drying efficiency, drying degree, and drying uniformity.
