Description

Technical Field

[0001] The utility model relates to the technical field of anaerobic reactors, in particular to an anaerobic internal rotary water distributor for evenly distributing water. Background Art

[0002] With the rapid development of my country's society and industry, the wastewater it produces not only harms the environment, but also hinders the development of the industry. Various forms of anaerobic reactors are usually used to treat wastewater. The wastewater flows from bottom to top in the reactor, and the anaerobic reaction occurs in the process of contact between wastewater and sludge particles. The biogas (mainly methane and carbon dioxide) produced under anaerobic conditions causes internal circulation. Some gases formed in the sludge layer attach to the sludge particles. The attached and unattached gases rise to the top of the reactor. The sludge rising to the surface hits the bottom of the gas emitter of the three-phase reactor, causing degassing of the sludge flocs with attached bubbles. After the bubbles are released, the sludge particles will settle to the surface of the sludge bed. The attached and unattached gases are collected in the gas collecting chamber of the three-phase separator at the top of the reactor, and the purified water flows out from the upper part of the reactor.

[0003] In existing technologies, ensuring adequate contact between sludge and wastewater is a crucial requirement for the successful operation of anaerobic reactors. Multiple water distribution pipes are typically installed at the bottom of the reactor to facilitate the reaction of wastewater and sludge. However, in practice, this mixing and reaction between wastewater and sludge is poor, resulting in uneven water distribution, which slows the reaction rate and reduces the reactor's treatment efficiency. To address this issue, we propose an anaerobic internal rotary water distributor that provides uniform water distribution. Utility Model Content
