Abstract

The invention discloses an intelligent low energy consumption sludge low-temperature drying system. The system comprises a sludge feed device (1), a drying tank (2), a dehumidifying and heating device(3), a dust removing device (4) and a gas pipeline, wherein the sludge feed device (1) is arranged on the drying tank (2) and is connected with the drying tank (2); the drying tank (2) is connected with the dehumidifying and heating device (3) through the gas pipeline; the dust removing device (4) is arranged between the drying tank (2) and the dehumidifying and heating device (3); a sludge outlet (2-5) is formed in the bottom of the drying tank (2); an automatic sampling device (7) is used for automatically sampling sludge in the drying tank (2); a water content online detection device (9) is used for detecting the water content of sampled sludge, and the sludge conveying speed of the drying tank (2) is adjusted according to the detection result of the water content. The intelligent lowenergy consumption sludge low-temperature drying system has the advantages of high energy utilization, and real-time detection on sludge water content variation through the water content online detection device.

Description

technical field [0001] The invention relates to the field of sludge drying equipment, in particular to an intelligent low-temperature sludge drying system with low energy consumption. Background technique [0002] Pollutants contained in sludge generally have a high calorific value, but due to the existence of a large amount of water, this part of the calorific value cannot be utilized. If the sludge with high moisture content is incinerated, not only will the calorific value not be obtained, but also a large amount of supplementary fuel is required to complete the combustion. If the moisture content of the sludge is reduced to a certain level, combustion is possible, and the heat obtained by combustion can meet the needs of part or even all of the drying. By the same token, reducing moisture content is also key in other applications. Therefore, sludge drying or semi-drying is the first step in sludge resource utilization. [0003] At present, the commonly used drying sys...
