The utility model relates to a desulfurization tower, which comprises a desulfurization tower body, an annular flue gas baffle, a closed annular flue gas duct formed between the annular flue gas baffle and the inner wall of the desulfurization tower, a plurality of flue gas outlets are arranged at the bottom of the annular flue gas baffle, a water outlet is arranged at the lower part of the desulfurization tower body, the height of the water outlet is higher than the bottom end of the flue gas outlet, and water is stuffed over the annular flue gas baffle The filter board and the water-tight filter board are provided with a plurality of smoke intake holes, and a sleeve is arranged on the smoke intake holes, and a smoke intake hood is sleeved on the sleeve. A plurality of through holes are arranged on the side wall under the top of the sleeve, and a demister is arranged above the water-tight filter board. Through the exhaust pipe, the flue gas in the annular flue can be directed to the water quality at the bottom of the desulfurization tower body for preliminary dust removal and desulfurization, and through the combination of the hood and casing on the water-tight filter board, dust removal and desulfurization of the flue gas can be carried out again, which can greatly increase the absorption of sulfur dioxide in the flue gas and greatly reduce the sulfur element carried in the flue gas.

一种脱硫塔
本技术具体涉及一种脱硫塔。
技术介绍
众所周知,烟气脱硫是控制SO2污染以及酸雨的有效办法。在烟气脱硫技术的发展过程中,喷淋塔是最早采用的脱硫反应形式,它的优点是能够形成较大的气液接触面积,同时系统的液气比可以较小。为了保证良好的脱硫效果,浆液喷射形成液滴粒径越小,则脱硫效率越高。一般的喷淋塔产生的液滴粒径为1mm以上,脱硫效率可达95%左右,能够满足较早实行的200mg/L的排放标准。然而,随着新的排放标准的出台及实施,现有的脱硫装置难以满足现阶段国家对二氧化硫排放浓度限值的要求,为了达到该要求,同时节约建设成本,最为经济的做法是对现有脱硫部分进行提效改造。
技术实现思路
本技术的目的在于提供一种脱硫、除尘效果好的脱硫塔。本技术采用的技术方案为:一种脱硫塔,包括脱硫塔体,所述脱硫塔体顶部设有出烟口,所述脱硫塔体中设有环形烟气挡板,所述环形烟气挡板与脱硫塔体内壁形成一封闭的环形烟道,所述脱硫塔体外壁上设有与环形烟道相通的进烟口,所述环形烟气挡板的底部设有多个两端开口的出烟管,所述出烟管的顶端向环形烟道中延伸,所述出烟管的底端向脱硫塔体底部延伸,所述脱硫塔体下部 ...
