背景技术Background technique
曝气是利用好氧生物降解的原理来进行污水处理的一项生化处理过程，传统的曝气设备根据双膜(水膜、气膜)理论来设计曝气设备，如机械鼓风曝气、叶轮曝气机、曝气增氧泵等。射流曝气是利用水射流原理来进行气、水混合，以达到曝气目的。传统射流曝气装置采用蝶式结构，四周均匀的圆形分布，对于一般较大污水系统而言，常用此类射流曝气装置，但对于矩阵排列的曝气设备和矩形污水反应池而言，其搅拌、曝气作用在各个交叉界面及曝气中心点而言是不平衡的。同样，在不同的水深深度也存在着不平衡，这会对曝气效果带来影响。Aeration is a biochemical process of sewage treatment using the principle of aerobic biodegradation. Traditional aeration equipment is designed according to the theory of double film (water film, air film), such as mechanical blast aeration, Impeller aerator, aeration and aeration pump, etc. Jet aeration is to use the principle of water jet to mix air and water to achieve the purpose of aeration. The traditional jet aeration device adopts a butterfly structure and is evenly distributed in a circle around it. For generally large sewage systems, this type of jet aeration device is commonly used, but for matrix-arranged aeration equipment and rectangular sewage reaction tanks, Its stirring and aeration effects are unbalanced in terms of each cross interface and aeration center point. Similarly, there is also an imbalance at different water depths, which will affect the aeration effect.

本实用新型针对现有技术存在的缺陷，依据气膜、液膜共相共膜过渡原理，能产生微小气泡，根据大型模拟系统实验基础上而设计改进的一种新型矩形射流曝气装置。The utility model aims at the defects existing in the prior art, and is a novel rectangular jet aeration device designed and improved on the basis of the large-scale simulation system experiment based on the transition principle of gas film and liquid film, which can generate tiny air bubbles.

具体实施方式Detailed ways
下面结合附图和实施例对本实用新型进一步加以说明。Below in conjunction with accompanying drawing and embodiment the utility model is further described.
实施例：如附图1、2所示，本实施例为圆形结构，装置中部设有上进水口1及下进气孔2，下部设有若干用以在好氧反应池池底安装固定的支架7，圆形结构中分布有十个与上进水口1及下进气口2相通的射流曝气器，射流曝气器的分布夹角根据好氧反应池长宽比确定；每个射流曝气器设有两个喷嘴，即收缩性的水射流喷嘴3和扩散型的气水混合喷嘴4；8为气水湍流混合室，在气水湍流混合室8内来自1与2的水流与气流形成增压湍流气水混合体，将气水混合液气泡分散成微小的气雾状，并通过气水混合喷嘴4将其高速射向好氧反应池，达到了好氧反应的要求；本实施例还包括上下盖板6、5。Embodiment: As shown in accompanying drawings 1 and 2, this embodiment is a circular structure, and the middle part of the device is provided with an upper water inlet 1 and a lower air inlet 2, and the lower part is provided with a number of holes for installation and fixing at the bottom of the aerobic reaction pool. Bracket 7, ten jet aerators connected to the upper water inlet 1 and the lower air inlet 2 are distributed in the circular structure, and the distribution angle of the jet aerators is determined according to the aspect ratio of the aerobic reaction tank; each jet aerator The aerator is provided with two nozzles, i.e., a shrinking
由于污水站(厂)因限制或设计整体安排需要，好氧反应池往往不是规整的正方形、长方形或圆形。本实施例应用于长方形好氧池，长20米、宽16米，最合理的方法是布6个射流曝气设备。但每个射流曝气器设备理论上需服务的面积为8米×6.67米，并非正方形或圆形。因此为适应这种变化，如附图1所示，本实施例的射流曝气设备设计时，十个射流曝气器的分布不是均匀的，从A′沿逆时针算起，两两之间其夹角分别为35°、33.5°、43°、33.5°、35°(另一半分布与之对称)。本实施例安装时A-A′轴与长边平行，这样就能基本修正由于好氧池尺寸不一的原因造成的射流曝气分布不均的问题。Due to the limitation of the sewage station (plant) or the overall arrangement of the design, the aerobic reaction tank is often not a regular square, rectangle or circle. This embodiment is applied to a rectangular aerobic pool with a length of 20 meters and a width of 16 meters. The most reasonable method is to arrange 6 jet aeration devices. However, each jet aerator device theoretically needs to serve an area of 8 meters by 6.67 meters, which is not square or circular. Therefore, in order to adapt to this change, as shown in Figure 1, when the jet aeration equipment of this embodiment is designed, the distribution of the ten jet aerators is not uniform, counting from A' counterclockwise, between two The included angles are 35°, 33.5°, 43°, 33.5°, 35° (the other half is symmetrically distributed). When this embodiment is installed, the A-A' axis is parallel to the long side, so that the problem of uneven distribution of jet aeration caused by the different sizes of the aerobic tanks can be basically corrected.
本实施例，射流曝气装置的直径为1.4米，进水管管径∮250mm，水流喷嘴管径为∮80mm，喷嘴最小处管径为∮40mm；气水混合喷嘴管径为∮150mm，喷嘴口带一个漏斗外形，有利于气水向上、下周围发散。In this embodiment, the diameter of the jet aeration device is 1.4 meters, the diameter of the water inlet pipe is ∮250mm, the diameter of the water nozzle is ∮80mm, and the diameter of the smallest part of the nozzle is ∮40mm; the diameter of the air-water mixing nozzle is ∮150mm, and the nozzle opening With a funnel shape, it is conducive to the upward and downward diffusion of air and water.
本实用新型装置结构简单，即有利于制造工艺的简化，又有利于减少水射能及气体能的衰减。在实际使用中污水中有多种介质(水、气及污染物)存在，经过射流曝气作用，加速了污泥中好氧微生物的生化作用，提高污水处理效果。The device of the utility model has a simple structure, which not only facilitates the simplification of the manufacturing process, but also reduces the attenuation of water injection energy and gas energy. In actual use, there are many kinds of media (water, air and pollutants) in the sewage. After jet aeration, the biochemical action of aerobic microorganisms in the sludge is accelerated, and the sewage treatment effect is improved.
