Abstract
The invention discloses a fixed spiral diffuser, comprising clockwise spiral members, an aeration circular barrel and anticlockwise spiral members, wherein the clockwise spiral members are connected to the aeration circular barrel; the aeration circular barrel is connected to the anticlockwise spiral members; the clockwise spiral members are connected to the anticlockwise spiral members; the clockwise spiral members and the anticlockwise spiral members are arranged alternatively in the aeration circular barrel; spiral directions of adjacent two members are opposite; two anticlockwise spiral members are arranged within three clockwise spiral members; each clockwise spiral member and each anticlockwise spiral member are connected and fixed to the aeration circular barrel through plug welding; and the spiral members are formed by twisting according to included angles of 180 degrees and are made of corrosion-resistant high alloy structural steel SUS316. The fixed spiral diffuser has the advantages of simple structure, convenient installation, complete oxygenation, uniform mixing and stirring, safety and reliability, etc.
Description
Technical field
The present invention relates to a kind of fixing spiral scatterer, be particularly useful for the aeration of the activated sludge process in the treatment of Organic Wastewater process of sewage work.
Background technology
Sewage work utilizes the microorganism flco of suspension growth to process the activated sludge method of organic waste water one class aerobe, its process of purifying liquid waste is mainly by adsorbing, microbial metabolism, cohesion and the large process composition of precipitation three, be called again aerobe facture, the synthetic oxygen that all needs of organic matter degradation and organism participates in.There is no sufficient dissolved oxygen, aerobic microbiological can not be survived, and more can not bring into play oxygenolysis, also must make microorganism, organism and oxygen fully contact as an effective treatment process simultaneously, and it will be indispensable therefore mixing and stir.
Present most sewage work is many realizes oxygenation and mixing by aerator, but because sludge concentration in the capabilities limits of water dissolution oxygen and mixed solution is larger, the diffusional resistance of oxygen in liquid phase is larger, so the oxygen of supplying with can not all be absorbed by water, different aerator oxygenation capacities are also different.
Summary of the invention
The present invention has developed a kind of fixing spiral scatterer, its objective is and provides a kind of simple in structure, and it is convenient to install, and oxygenation is complete, mixing and stirring, safe and reliable fixing spiral scatterer.
For achieving the above object, apparatus of the present invention are achieved through the following technical solutions.Fixing spiral scatterer, comprise clockwise screw element, aeration circular cylinder body, screw element counterclockwise, screw element is connected with aeration circular cylinder body clockwise, aeration circular cylinder body is connected with counterclockwise screw element, screw element is connected with counterclockwise screw element clockwise, screw element is arranged inner the replacing of aeration circular cylinder body with counterclockwise screw element clockwise, the hand of spiral that is adjacent two elements is contrary, the quantity of screw element is that 3 centres of clockwise screw element are mingled with 2 of counterclockwise screw elements, every clockwise screw element and counterclockwise screw element and aeration circular cylinder body select plug welding to be connected and fixed, screw element is to form according to 180 ° of angle distortions, material is selected anti-corrosion high alloy-structural steel SUS316.
The invention has the beneficial effects as follows, utilize clockwise screw element and replacing of counterclockwise screw element to arrange, air enters aeration circular cylinder body by bottom, forms that mixing wastewater with air liquid repeatedly collides with wall and screw element plate face, cuts apart in cylinder, roundabout rising.Oxygenation is mixed completely after being evenly arranged in aeration tank, integral device has simple in structurely, and it is convenient to install, and oxygenation is complete, mixing and stirring, the advantage such as safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fixing spiral scatterer of the present invention.
