Aeration system of energy-saving homogenizing tank

Abstract

The invention relates to an aeration system of an energy-saving homogenizing tank, which comprises a homogenizing tank and aeration pipes, the included angle between one side wall of the homogenizingtank and the tank bottom is larger than 90 degrees to form a slope surface, the tank bottom is a plane, a plurality of aeration pipes are arranged on the slope surface at preset intervals in the inclination direction of the slope surface, and aeration holes are formed in each aeration pipe at preset intervals. The sludge dewatering system has the beneficial effects that when the sludge dewateringsystem is used for dewatering sludge, the sludge fluidity is high, feeding is convenient, and the phenomena that feeding is slow and the sludge cannot enter the system but water can can be solved.

Description

technical field [0001] The invention relates to the technical field of sludge treatment and disposal, in particular to an energy-saving homogenization tank aeration system. Background technique [0002] There are many types of waterways in rivers and lakes in my country, and there are huge differences in the mud properties of the dredged and discharged silts. The particle size of the silt particles ranges from medium-coarse sand to fine silt particles. The organic matter content is usually below 10%, but in some areas the organic matter can reach more than 70%. The traditional sludge treatment and disposal technology is difficult to meet various requirements, especially the high organic matter sludge has a loose structure and many internal pores, and the traditional sludge treatment process is very difficult to handle. [0003] In the homogenization tank, problems such as uneven sludge modification, high viscosity and low fluidity of organic sludge flocs are often encountered...

Problems solved by technology

[0002] There are many types of waterways in rivers and lakes in my country, and there are huge differences in the mud properties of the dredged and discharged silts. The particle size of the silt particles ranges from medium-coarse sand to fine silt particles. The organic matter content is usually below 10%, but in some areas the organic matter can reach more than 70%. The traditional sludge treatment and disposal technology is difficult to meet various requirements, especially the high organic matter sludge has a loose structure and a lot of internal pores, and the traditional sludge treatment process is very difficult to handle

[0003] In the homogenization tank, problems such as uneven sludge modification, high viscosity and low fluidity of organic sludge flocs make it difficult for the feed pump to enter the sludge, etc.

Aeration and agitation in the homogenization tank is an important means to homogenize the sludge. At present, the sludge is usually mixed by the backflushing of the plate and frame machine or by laying a special aeration system. The backflushing of the plate and frame machine is a link in the filter press process. , Exclude excess silt during feeding to avoid slurry leakage during discharge, backflush aeration is strong but the time is short and the range is small, and the silt cannot be fully homogenized

Laying a special aeration system can make the sludge mix evenly and increase the energy consumption of the process. How to fully homogenize the sludge while saving energy and reducing consumption is a difficult point in the sludge disposal project
