AI Technical Summary

Technical Problem

In existing stripping equipment, the deposition and adhesion of suspended particulate matter on the surface of the packing material leads to a decrease in the porosity of the packing material, uneven gas-liquid distribution, reduced processing efficiency, and even the need for frequent shutdowns for cleaning, increasing operating costs and affecting stability.

Method used

The system adopts a multi-layer packing frame structure, including an outer ring frame, an inner circular frame, and a middle ring frame. The automatic unblocking and leveling of the packing layer is achieved through a lifting component and a material feeding component. The lifting and lowering of the packing frame is controlled by a limiting structure and a one-way damping mechanism. The material feeding component disperses the particles in the packing layer, and the leveling mechanism ensures uniform distribution, thereby improving the gas-liquid mass transfer effect.

Benefits of technology

It effectively solved the problem of poor liquid flow caused by water accumulation in the packing layer, improved the operational stability and processing efficiency of the equipment, reduced operating costs, and ensured the continuity and stability of the processing.

Abstract

The invention relates to the technical field of sewage treatment, and particularly discloses breeding wastewater treatment equipment which comprises a tank body, a plurality of filler frames are arranged in the tank body up and down, an air blowing device and a liquid outlet are arranged at the inner bottom of the tank body, and a liquid inlet and an exhaust port are formed in the top of the tank body. The packing frame is composed of an outer ring frame, an inner round frame and at least one middle ring frame in a sleeved mode, the outer ring frame, the inner round frame and the middle ring frame are connected in an up-down sliding mode, limiting structures for limiting the sliding range are arranged among the outer ring frame, the inner round frame and the middle ring frame, and the outer ring edges of the bottoms of the middle ring frame and the inner round frame are all downwards provided with annular edges. The outer ring frame, the inner round frame, the middle ring frame and the annular edge are all of a porous structure, when excessive water is accumulated on the filler frame, the lifting assembly enables the outer ring frame and the middle ring frame to descend, the material stirring assembly moves upwards relative to the filler layer, and in the ascending process, the material stirring assembly scatters filler particles in the middle and brings the filler particles to the upper portion, so that filler is redistributed, and filler holes can be dredged.
