Description

一种新型的双塔式高效脱硫除尘器A new double-tower high-efficiency desulfurization and dust collector

技术领域 technical field

本发明创造涉及一种脱硫除尘器，特别是一种新型的双塔式高效脱硫除尘器。 The invention relates to a desulfurization and dust collector, in particular to a novel double-tower high-efficiency desulfurization and dust collector.

背景技术 Background technique

现阶段烟气脱硫除尘器分为三类：湿法脱硫、半干法脱硫、干法脱硫技术。多为单极处理，除尘效率低，脱硫效率低，且不消烟。生产成本高、使用寿命短。 At present, flue gas desulfurization dust collectors are divided into three categories: wet desulfurization, semi-dry desulfurization, and dry desulfurization technologies. Most of them are single-pole treatment, with low dust removal efficiency, low desulfurization efficiency, and no smoke elimination. The production cost is high and the service life is short.

发明内容 Contents of the invention

为了解决上述存在的技术问题，本发明创造提供一种新型的双塔式高效脱硫除尘器，该除尘器集脱硫除尘为一体，消烟除尘效果好。 In order to solve the above-mentioned technical problems, the present invention provides a novel double-tower high-efficiency desulfurization and dust collector, which integrates desulfurization and dust removal, and has a good smoke and dust removal effect.

本发明创造的目的是这样实现的：一种新型的双塔式高效脱硫除尘器，其特征在于：S弯旋转式脱硫除尘塔与冲击湍流式脱硫除尘塔通过烟道连接，在烟道上安装风机； The purpose of the invention is achieved in this way: a new double-tower high-efficiency desulfurization and dust collector is characterized in that: the S-curved rotary desulfurization and dust removal tower is connected with the impact turbulent flow desulfurization and dust removal tower through a flue, and a fan is installed on the flue ;

所述的S弯旋转式脱硫除尘塔的塔身上设有进烟口，塔内进烟口的两侧分别设有S形漩涡通道，在塔身中上部设有折流板Ⅰ，在塔身底部设有灰斗Ⅰ； The tower body of the S-curved rotary desulfurization and dust removal tower is provided with a smoke inlet, S-shaped vortex passages are respectively arranged on both sides of the smoke inlet in the tower, and a baffle plate I is arranged at the middle and upper part of the tower body. There is an ash hopper I at the bottom;

所述的冲击湍流式脱硫除尘塔的塔身顶部设有出风口，在塔身底部设有灰斗Ⅱ；烟道末端位于冲击湍流式脱硫除尘塔的塔身内，在烟道出口处设有烟气冲击体，在塔身中上部设有折流板Ⅱ。 The top of the impact turbulent desulfurization and dust removal tower is provided with an air outlet, and an ash hopper II is arranged at the bottom of the tower; The gas impact body is equipped with a baffle plate II in the middle and upper part of the tower body.

所述的S弯旋转式脱硫除尘塔的塔身上设置若干个雾化喷嘴。 The tower body of the S-curved rotary desulfurization and dust removal tower is provided with several atomizing nozzles.

所述的烟道末端设有若干个雾化喷嘴。 The end of the flue is provided with several atomizing nozzles.

本发明创造采用双塔式结构，在前端设置一级S弯旋转式脱硫除尘塔，后端设置一级冲击湍流式脱硫除尘塔通过烟道连接风机。烟气被风机从S弯旋转式脱硫除尘塔的进烟口吸入，由于S弯旋转式脱硫除尘塔内设置多组雾化喷嘴，雾化喷嘴喷出无死角全区域碱水水雾对烟气进行初步净化，然后烟气通过S形漩涡通道进行特殊水旋流，利用烟气自身的动能产生气动旋流，气液两相充分接触，进行传质反应，清除大部分S02、S03、CO及灰尘，再通过S弯旋转式脱硫除尘塔上部设置的折流板Ⅰ进行脱水，烟气出S弯旋转式脱硫除尘塔后通过风机被高速吹入冲击湍流式脱硫除尘塔，由于烟道末端设置在塔内，并在烟道末端设置雾化喷嘴，通过雾化喷嘴净化后，进入烟气冲击体，利用高强度水压使通过烟气冲击体的烟气完全净化，最后烟气变为纯净的带水气体通过折流板Ⅱ过滤水分，最终烟气从出风口排出除尘器，其中折流板根据重力、惯性力、离心力等气水分离原理设计，脱水效率高（出口液态水份浓度<100mg/Nm3），确保风机正常运行。 The invention adopts a double-tower structure, with a first-stage S-curved rotary desulfurization and dust removal tower at the front end, and a first-stage impact turbulent flow desulfurization and dust removal tower at the rear end, which is connected to the fan through the flue. The flue gas is inhaled by the fan from the smoke inlet of the S-curved rotary desulfurization and dust removal tower. Since the S-curved rotary desulfurization and dust removal tower is equipped with multiple groups of atomizing nozzles, the atomizing nozzles spray alkali water and water mist in the whole area without dead ends to affect the flue gas. After preliminary purification, the flue gas passes through the S-shaped vortex channel for special water swirl flow, using the kinetic energy of the flue gas itself to generate aerodynamic swirl flow, the gas-liquid two-phase is fully contacted, and the mass transfer reaction is carried out to remove most of the S0 2 , S0 3 , CO and dust are dehydrated through the baffle plate I set on the upper part of the S-curved rotary desulfurization and dust removal tower. The end is set in the tower, and an atomizing nozzle is installed at the end of the flue. After being purified by the atomizing nozzle, it enters the flue gas impact body, and the flue gas passing through the flue gas impact body is completely purified by high-intensity water pressure. The pure water-laden gas passes through the baffle plate II to filter the water, and finally the flue gas is discharged from the dust collector from the air outlet. The baffle plate is designed according to the principle of gas-water separation such as gravity, inertial force, and centrifugal force, and the dehydration efficiency is high (the liquid moisture at the outlet Concentration <100mg/Nm 3 ), to ensure the normal operation of the fan.

本发明创造集脱硫除尘为一体，通过两级脱硫除尘塔，达到了高效脱硫无烟无尘的目的。该装置不排废水，无二次污染，工艺简单，易操作维护，脱硫率在99%左右，除尘率在99%左右，脱硫除尘效果好。  The invention integrates desulfurization and dust removal, and achieves the purpose of efficient desulfurization without smoke and dust through two-stage desulfurization and dust removal towers. The device does not discharge waste water, has no secondary pollution, is simple in process, easy to operate and maintain, has a desulfurization rate of about 99%, a dust removal rate of about 99%, and a good desulfurization and dust removal effect. the
