Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stirring devices, in particular to an energy-saving airflow stirring device. Background Art
[0002] The "ultrafiltration + chemical softening + reverse osmosis" combination, as a third-generation deep treatment process for waste incineration plant leachate, achieves zero discharge and full reuse of leachate. This not only eliminates the discharge of pollutants in the leachate, but also fully reuses the treated leachate, thereby promoting the recycling of water resources. The target of chemical softening in the leachate treatment process is the ultrafiltration water, and the added reagent is primarily lime. The chemical softening reaction must be carried out in four tanks, namely the No. 1 reaction tank, the No. 2 reaction tank, the sludge tank, and the circulation tank. Considering the residence time required for the reaction between the ultrafiltration water and the lime slurry, the mixing uniformity, and the easy precipitation of lime, all four tanks must be equipped with agitators and operate continuously throughout the day. Existing mixing equipment uses mechanical agitators, which not only increases the initial investment but also exponentially increases the subsequent operating power consumption and maintenance costs. Utility Model Content
[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an energy-saving airflow stirring device. The present invention uses compressed air instead of traditional mechanical stirring, which has many advantages, such as saving investment equipment costs, facilitating operation and control, reducing energy consumption and maintenance costs, and improving the softening effect.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] An energy-saving air flow stirring device includes an air intake pipe, one end of the air intake pipe is connected to a compressed air main pipe, the other end of the air intake pipe is connected to an air buffer chamber, and a plurality of branch pipes are evenly distributed around the circumference of the air buffer chamber, and the plurality of branch pipes are distributed in a spoke-like manner;
[0006] Each branch pipe is provided with a horizontal air outlet hole penetrating in the horizontal direction and a vertical air outlet hole penetrating in the vertical direction.
[0007] Furthermore, the air intake pipeline includes a horizontal section and a vertical section that are connected. The air intake end of the horizontal section is connected to the compressed air main pipe, and the air outlet end of the vertical section is connected to the air buffer chamber.
[0008] Furthermore, the horizontal section is equipped with an air pressure reducing valve and an air intake manual main valve, and the air intake manual main valve is arranged close to the compressed air main pipe.
[0009] Furthermore, the number of the branch pipes is at least 6.
[0010] Furthermore, the cross-section of the branch pipe is circular.
[0011] Furthermore, the cross-section of the branch pipe is rectangular.
[0012] Furthermore, one end of the branch pipe is connected to the air buffer chamber, and a plug is installed at the other end of the branch pipe.
[0013] The gas agitation device primarily utilizes compressed air to agitate the water. Multiple branch pipes are located in various locations, each with air outlets both horizontally and vertically. This ensures horizontal flow along the bottom of the water while also providing upward momentum. The even distribution of the branch pipes maximizes their working range across the pool bottom, ensuring thorough, uniform, and stable mixing. During the agitation process, the wastewater experiences increased contact between air and water, enhancing the softening, decarbonization, and stripping effects.
[0014] The beneficial effects of the utility model are as follows: the utility model has a simple structure, a reasonable design, and has the following advantages:
[0015] (1) The horizontal and vertical air outlets on each branch pipe discharge air to mix and stir the water. The air discharged from the horizontal air outlet propels the water at the bottom in a swirling direction, and the air discharged from the vertical air outlet increases the upward momentum of the water. The swirling and vertical flows increase the mixing strength of the entire pool. Using gas instead of mechanical stirring facilitates operation and maintenance, saves investment and operation and maintenance costs, and is also easy to repair.
[0016] (2) The utility model mainly processes the ultrafiltration water produced by the filtration biochemical system. The alkalinity and hardness in the water are relatively high. In this chemical softening stage, adding lime not only provides the environment and conditions required for chemical softening, but also the entry of air increases the alkalinity and hardness of the water in this environment. The carbon dioxide gas is precipitated with the air, which provides an auxiliary role for decarbonization and also enhances the effect of chemical softening. BRIEF DESCRIPTION OF THE DRAWINGS
