Description
技术领域technical field
本实用新型涉及脱硫塔技术领域，尤其涉及一种应用于脱硫塔上的组合式高效除雾装置。The utility model relates to the technical field of desulfurization towers, in particular to a combined high-efficiency mist removal device applied to a desulfurization tower.
背景技术Background technique
目前，我国大部分烟气脱硫采用湿法脱硫工艺，经脱硫塔处理后的烟气携带有大量的浆液雾滴，导致脱硫塔后续处理设备及部件严重腐蚀、造成“烟雨”问题严重危害环境。At present, most of the flue gas desulfurization in my country adopts the wet desulfurization process. The flue gas treated by the desulfurization tower carries a large number of slurry droplets, which leads to serious corrosion of the subsequent treatment equipment and components of the desulfurization tower, and causes the "smoky rain" problem that seriously harms the environment.
因此，在脱硫塔出口必须安装除雾器，用于脱硫后水汽饱和的烟气除雾。目前，绝大多数湿法脱硫塔顶部均设有两级折流板除雾器，首先，该型除雾器结构简单、对中等尺寸和大尺寸雾滴的捕获效率高，无法捕获粒径小于20μm的细小液滴，从而导致了脱硫后的烟气严重带水现象。其次，折流板除雾器是利用烟气中液滴的惯性力撞击板片来分离气水，故除雾器捕获液滴的效率随烟气流速的增加而增加，流速高，作用于液滴的惯性大，有利于气水分离，但当流速超过某一限值时，烟气会剥离板片上的液膜，造成二次带水，从而降低除雾效率。Therefore, a mist eliminator must be installed at the outlet of the desulfurization tower for demisting the water vapor-saturated flue gas after desulfurization. At present, most of the wet desulfurization towers are equipped with a two-stage baffle plate mist eliminator at the top. First of all, this type of mist eliminator has a simple structure and high capture efficiency for medium-sized and large-sized droplets, and cannot capture particles smaller than 20μm fine droplets, resulting in serious water-carrying phenomenon in the flue gas after desulfurization. Secondly, the defogger uses the inertial force of the droplets in the flue gas to hit the plates to separate the gas and water, so the efficiency of the demister to capture the droplets increases with the increase of the flow rate of the flue gas. The inertia of the droplets is large, which is conducive to the separation of gas and water, but when the flow rate exceeds a certain limit, the flue gas will peel off the liquid film on the plate, resulting in secondary water entrainment, thereby reducing the demisting efficiency.
发明内容SUMMARY OF THE INVENTION
本实用新型的目的在于克服上述技术的不足，提供一种组合式高效除雾装置，改善原有折流板除雾器针对小液滴捕集效率低及二次带水的技术问题。The purpose of the present utility model is to overcome the deficiencies of the above technologies, provide a combined high-efficiency mist removal device, and improve the technical problems of the original baffled mist eliminator for low droplet collection efficiency and secondary water entrainment.

The baffle plate mist eliminator and the tube bundle mist eliminator, the baffle plate mist eliminator and the tube bundle mist eliminator are respectively clamped up and down by two support ring plates; the support ring plate on the lower surface of the tube bundle mist eliminator is provided with There are two layers, and a rectifying grid plate is sandwiched between the two layers of support ring plates; the outer edge of the support ring plate is fixed on the inner wall of the desulfurization tower, and the inner diameter of the support ring plate is slightly smaller than the inner diameter of the desulfurization tower; Between the tube bundle demister and the baffle demister, and below the baffle demister are respectively installed flushing water pipes that spray upward.
进一步地，所述管束除雾器和折流板除雾器之间的冲洗水管的出水口分别对准管束除雾器的各束管。Further, the water outlets of the flushing water pipes between the tube bundle mist eliminator and the baffle plate mist eliminator are respectively aligned with the tubes of the tube bundle mist eliminator.
进一步地，所述冲洗水管通过两端安装在脱硫塔内壁上的水管支撑梁固定。Further, the flushing water pipe is fixed by the water pipe support beams installed on the inner wall of the desulfurization tower at both ends.
进一步地，所述整流格栅板与折流板除雾器下表面的支撑环板的底面与脱硫塔内壁之间连接有三角状的加强筋。Further, a triangular reinforcing rib is connected between the rectifying grid plate and the bottom surface of the support ring plate on the lower surface of the baffle plate demister and the inner wall of the desulfurization tower.
进一步地，所述整流格栅板与折流板除雾器下表面的支撑环板的底面沿直径方向分别设置有环板支撑梁，环板支撑梁的两端安装在脱硫塔内壁上。Further, the bottom surface of the support ring plate on the lower surface of the rectifier grid plate and the baffle plate mist eliminator are respectively provided with ring plate support beams along the diameter direction, and both ends of the ring plate support beam are installed on the inner wall of the desulfurization tower.
本实用新型的有益效果为：相对目前的两级折流板除雾器，通过管束除雾器代替上级的折流板除雾器，对细小的液滴有更高的捕集效率，除雾效果更好，且所需安装空间小，且所需冲洗水量小，节约水耗；其次本装置在实现深度除尘的同时，相比较加装湿式静电除尘器，投资省、运行费用低，占用空间小；同时本装置通过支撑环板固定，固定强度大，不易脱落，不影响除雾效率。The beneficial effects of the utility model are as follows: compared with the current two-stage defogger defogger, the tube bundle defogger replaces the upper-level defogger defogger, which has higher collection efficiency for fine droplets and eliminates fog. The effect is better, and the required installation space is small, and the required amount of flushing water is small, which saves water consumption; secondly, this device achieves deep dust removal, and compared with the installation of wet electrostatic precipitators, the investment is low, the operating cost is low, and the space is occupied. At the same time, the device is fixed by the support ring plate, the fixing strength is large, it is not easy to fall off, and the demisting efficiency is not affected.
