Description

TECHNICAL FIELD

[0001] The present application relates to sludge solidification technology, in particular to a reservoir sludge in-situ solidification resource utilization device. BACKGROUND

[0002] Dredging and dredging is a key engineering technology for improving and restoring rivers, lakes, reservoirs and other water environments. At present, it has been widely used in the field of water environment treatment and ecological restoration in China. Current sludge disposal technologies mainly include physical dewatering method, heating sintering method and solidifying agent method. Physical dewatering method relies on natural drying, which has a long processing period and seriously affects the progress of the project; the heating sintering method has complex process steps, high energy consumption and cost, and long construction period. The above two methods are only suitable for small-scale and high-standard sludge treatment scenarios. In large-scale sludge disposal engineering practice, adding solidifying agent has become the most commonly used treatment method.

[0003] In large-scale sludge treatment, solidifying agent method needs to rely on sludge in-situ solidification equipment. The existing equipment is usually composed of a shell, a stirring barrel arranged at the bottom, and a nozzle installed on the stirring barrel. The nozzle is connected with a high-pressure powder conveying pipe, and the solidifying agent is sprayed into the sludge by using high-pressure gas, and then stirred and mixed by the stirring barrel, so that the solidifying agent and the sludge around the stirring barrel region are fully mixed to generate hard cementing material, thereby achieving the purpose of solidification.

[0004] However, such equipment has certain limitations in actual use: the operation mode of the bottom stirring barrel is relatively single, and it is difficult to fully mix the solidifying agent with the sludge around the stirring barrel region. In order to improve the mixing uniformity, the operator needs to frequently move the equipment shell to adjust the stirring position, which not only significantly increases the labor burden, but also seriously affects the treatment efficiency of the sludge. Therefore, it is necessary to optimize and improve the structure of the existing sludge in-situ solidification equipment, which has clear engineering necessity and application value. SUMMARY
