Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of water, wastewater, sewage or sludge treatment, and particularly relates to a dry sludge automatic loading system for a sludge dewatering workshop. BACKGROUND

[0002] Sludge dewatering treatment is an important link in the sewage treatment process, which mainly separates water from sludge through pressure or heating measures, so as to achieve the purposes of reducing sludge volume, reducing treatment cost, improving sludge treatment efficiency and reducing the risk of secondary pollution. After completing the sludge dewatering treatment, the dry sludge needs to be loaded and output. Although the municipal sludge after drying or pyrolysis treatment is different from the original municipal sludge, it is still in the form of fine particles and has certain fluidity, is easy to dust, and still has strong odor. How to ensure fast and automatic loading while reducing sludge dust and reducing the impact of odor on the surrounding environment is a problem that needs to be focused on in the sludge disposal process.

[0003] In actual engineering, the dry sludge loading form of the sewage treatment plant mainly includes tank loading and box loading. For dry sludge with a water content of ≦40% or pyrolysis products (biochar), tank loading and transportation are generally adopted.

[0004] In the existing dry sludge loading workshop, the loading process of sludge needs to be manually commanded on site, and the automatic control degree is low. It is difficult to completely automatically load the sludge in a closed state, and the personnel requirement is high. The feed inlet of the conventional tank loading vehicle is generally 3, while the material discharge port of the sludge dewatering workshop is fixed. Therefore, the loading vehicle is often moved to align the feed inlet of the loading vehicle with the discharge port for loading. This means that the horizontal distance of the loading area needs to be at least greater than the distance of the outermost 2 feed inlets to meet the movement requirement, which leads to a large working area and high civil construction cost. Another measure is that in order to reduce the loading area, the sludge vehicle does not completely enter the workshop, and the loading area is not completely closed. However, in this operation mode, the dust and high-concentration odor generated during the sludge pouring process will spread outward, thereby affecting the surrounding environment. Of course, for the latter, dust and odor removal equipment can also be used for assistance. However, the dust and odor removal measures of these equipment are often to perform air draft and treatment on the entire workshop, which has a large air draft volume and high operation cost, and the dust and odor removal effect is poor.

[0005] In summary, the environmental status and dust and odor problems of the sludge dewatering workshop loading area of the sewage treatment plant are common management difficulties and pain points. The traditional loading and dust removal mode cannot meet the increasingly strict regulatory requirements. Therefore, the research on dry sludge automatic loading and dust removal is very urgent.
