Abstract

The invention mainly aims to provide a sludge desiccation system. A technical scheme is as below: a sludge desiccation system comprises a drying chamber communicating with a hot-air pipeline and an auxiliary heat source pipeline; the drying chamber comprises a wet sludge inlet, a dry sludge outlet, a moisture exhaust and a sludge conveyor belt inside the drying chamber; the hot-air pipeline is communicating with a solar heat collector, which is communicating with a blower fan through an air channel; and the auxiliary heat source pipeline is provided with a temperature control valve. The desiccation system not only utilizes solar energy and heat tail gas or steam discharged by a factory effectively to enhance desiccation efficiency and desiccation effect, but also enhances operating stability of the desiccation system.

Description

technical field [0001] The invention relates to the field of solid waste treatment, in particular to a sludge drying system. Background technique [0002] At present, the drying of cyanobacteria mud / sludge uses solar energy, a new green energy source, but the application of solar drying technology has the problem of unstable use of solar energy, such as the intensity of solar energy and the change of seasons, the alternation of daylight, the weather, etc. The condition is directly related, so it directly affects the stable operation of the cyanobacteria mud / sludge drying system. At present, the main method to solve this problem is to use auxiliary energy, that is, when the heat provided by solar energy is not enough to realize the drying of cyanobacteria mud / sludge, the auxiliary energy is provided to the drying room. At present, most of this auxiliary energy is discharged from the factory hot exhaust or steam. However, there are certain problems in practical application, ...
