Problems solved by technology

[0003] However, with the development of sludge treatment technology, the way of sludge dewatering is also developing. The current technology is more inclined to the deep dehydration of sludge, that is, adding different conditioners (solution state) to sludge before sludge dehydration or solid powder) to condition the sludge to improve the dewatering perform

Abstract

The invention discloses an environment-friendly sludge conditioning and drying treatment device and belongs to the technical field of sludge treatment equipment. The environment-friendly sludge conditioning and drying treatment device comprise a chemical preparation device, a conditioning device, a dehydration drying device and a control device. The amount of sludge entering a drying drum can be metered precisely, and overload of the dehydration drying device is avoided; meanwhile, drying is performed by means of hot flue gas, and energy is used reasonably; the sludge is smashed uniformly by astirring push rod in a drying process and is pushed to advance, the drying process is uniform, the hot flue gas makes full contact with the sludge, the drying effect is good, the drying process is continuous and efficient, a secondary drying device is arranged, heat of wet flue gas is fully used, the energy use rate is high, and the drying effect is obvious.

Description

technical field [0001] The invention relates to an environment-friendly sludge conditioning and drying treatment device, which belongs to the technical field of sludge treatment equipment. Background technique [0002] The sludge produced by domestic sewage treatment plants or industrial wastewater treatment has a water content of 78%~85% after pressure filtration, which varies greatly. To further reduce the water content, reduce the volume, increase the strength and calorific value, conditioning is required. After conditioning and modifying with the agent, it is then subjected to high-pressure pressing to reduce its moisture content to about 60%, so as to meet the requirements of disposal or recycling. [0003] However, with the development of sludge treatment technology, the way of sludge dewatering is also developing. The current technology is more inclined to the deep dewatering of sludge, that is, adding different conditioners (solution state) to sludge before sludge de...
