Description
技术领域technical field
本发明涉及一种雾化盘，尤其是涉及一种环保工程用复合结构雾化盘。The invention relates to an atomizing disc, in particular to an atomizing disc with a composite structure for environmental protection engineering.
背景技术Background technique
环保工程用雾化盘是垃圾焚烧电厂尾气净化系统的核心组件，在高速旋转状态下，利用离心作用，使碱液与烟气充分混合，达到脱硫、脱硝的净化作用。应用中，在强碱及灰渣的冲刷下，极易受到磨损而失效。目前使用的钛合金雾化盘，使用寿命不到两个月，就遭到冲刷失效；经表面强化处理后，使用寿命仍不到三个月。The atomizing disc for environmental protection engineering is the core component of the exhaust gas purification system of the waste incineration power plant. Under the high-speed rotation state, the centrifugal effect is used to fully mix the lye and the flue gas to achieve the purification effect of desulfurization and denitrification. In application, under the erosion of strong alkali and ash, it is very vulnerable to wear and failure. The currently used titanium alloy atomizing disc has a service life of less than two months before being washed out; after surface strengthening treatment, the service life is still less than three months.
中国专利CN104162494A公开了一种用于实现将液体物料粉末化的雾化盘,包括相互连接的上盖板与下盖板，下盖板回转中心形成贯穿板体的连接柱，在下盖板表面容置槽中设有垫板，且垫板中心套筒套设于连接柱上，并通过压盖压紧固定，垫板的套筒部与垫板底面之间为圆弧过渡连接；上盖板上开设有进料区，上盖板与垫板两者外圆周面之间形成出料区。该发明公开的雾化盘的上盖板与下盖板采用钢质材料制成，为了减少磨损，通过在下盖板上开槽并在槽内嵌入碳化硅板体，使得硬度较大的物料进入高速旋转的雾化盘时，不会把下盖板表面磨损，从而可以对下盖板起到较好保护作用。但该发明所述雾化盘，没有对对钢质上盖板进行有效保护，在使用过程中，极易受到表面磨损，进而使该发明所述雾化盘整体失效。特别是该发明所述雾化盘其上盖板开了较大的进料孔，设为进料区，出料液滴较大，是一种用于将液体物料喷雾成粉末化的雾化盘，在既有冲刷、又有腐蚀的电厂尾气净化系统中时，不但易受到腐蚀，还存在碱液与烟气混合不充分的缺陷。此外，该发明采用碳化硅陶瓷作下盖板的护板，存在脆性大，成本高的问题。Chinese patent CN104162494A discloses an atomizing disc for powdering liquid materials, including an upper cover plate and a lower cover plate connected to each other, and the center of rotation of the lower cover plate forms a connecting column that runs through the plate body. There is a backing plate in the slot, and the central sleeve of the backing plate is set on the connecting column, and is fixed by pressing the gland. The sleeve part of the backing plate and the bottom surface of the backing plate are connected by an arc transition; the upper cover There is a feeding area on the top, and a discharging area is formed between the outer peripheral surfaces of the upper cover plate and the backing plate. The upper cover plate and the lower cover plate of the atomizing disc disclosed in the invention are made of steel materials. In order to reduce wear and tear, grooves are made on the lower cover plate and silicon carbide plates are embedded in the grooves so that materials with higher hardness enter When the atomizing disc rotates at high speed, it will not wear the surface of the lower cover, so that it can better protect the lower cover. However, the atomizing disc in this invention does not effectively protect the steel upper cover plate, and is easily subject to surface wear during use, which makes the atomizing disc in this invention fail as a whole. In particular, the upper cover plate of the atomizing disc described in this invention has a larger feeding hole, which is set as the feeding area, and the discharge droplets are larger. It is an atomizing device for spraying liquid materials into powders. When the disc is used in a power plant tail gas purification system that has both scour and corrosion, it is not only susceptible to corrosion, but also has the defect of insufficient mixing of lye and flue gas. In addition, the invention uses silicon carbide ceramics as the guard plate of the lower cover, which has the problems of high brittleness and high cost.

一种环保工程用复合结构雾化盘，由底盘及面盘组成，在面盘的背面设有三个突出结构，这样一方面增加了面盘的机械强度，更重要的是三个突出结构形成正三角形的形状，使连接最为稳定，底盘与面盘通过凹凸镶嵌连接。面盘背面的中间部位还设有固定螺栓，当雾化盘旋转时，使面盘与底盘保持紧密联动，面盘厚度为底盘厚度的70％。面盘采用耐磨复合陶瓷制作得到，厚度为5mm。耐磨复合陶瓷为氧化铝和氧化锆按重量比为8.5：1.5为主要化学成份混合形成的复合陶瓷。这种复合陶瓷是一种氧化锆增韧氧化铝陶瓷，具有硬度高、韧性好、耐磨耐腐蚀，制造成本比碳化硅陶瓷低等优点，底盘的材质为镍铬基合金，直径为220mm。An atomizing disc with a composite structure for environmental protection engineering is composed of a chassis and a face plate. There are three protruding structures on the back of the face plate. On the one hand, this increases the mechanical strength of the face plate. More importantly, the three protruding structures form a positive The triangular shape makes the connection the most stable, and the chassis and face plate are connected by concave-convex mosaic. There is also a fixed bolt in the middle of the back of the face plate. When the atomization plate rotates, the face plate and the chassis are closely linked. The thickness of the face plate is 70% of the thickness of the chassis. The dial is made of wear-resistant composite ceramics with a thickness of 5mm. Wear-resistant composite ceramics are composite ceramics formed by mixing alumina and zirconia in a weight ratio of 8.5:1.5 as the main chemical components. This composite ceramic is a zirconia toughened alumina ceramic, which has the advantages of high hardness, good toughness, wear resistance and corrosion resistance, and lower manufacturing cost than silicon carbide ceramics. The material of the chassis is nickel-chromium-based alloy with a diameter of 220mm.
