Description
技术领域technical field
本实用新型涉及一种烟气净化装置，属于烟气净化技术领域。The utility model relates to a flue gas purification device, which belongs to the technical field of flue gas purification.
背景技术Background technique
燃煤所排放的烟气中含有大量污染物，是主要大气污染源，造成严重的雾霾天气。目前，烟气或工业尾气常用的脱硫技术有石灰石-石膏法、氨法、双碱法等；烟气净化技术有选择性催化还原法、非选择性催化还原法以及低氮燃烧法等；烟气脱汞的技术主要有化学沉淀法和化学氧化法。上述方法均不能有效彻底地净化烟气，对雾霾天气的治理效果不佳。The flue gas emitted by coal burning contains a large amount of pollutants, which is the main source of air pollution and causes severe smog. At present, the desulfurization technologies commonly used for flue gas or industrial tail gas include limestone-gypsum method, ammonia method, double alkali method, etc.; flue gas purification technologies include selective catalytic reduction method, non-selective catalytic reduction method, and low-nitrogen combustion method; The technologies for mercury removal from gas mainly include chemical precipitation and chemical oxidation. None of the above methods can effectively and thoroughly purify the flue gas, and the control effect on haze weather is not good.
现有烟气中颗粒物的去除方法主要有过滤法、水吸附法、植物吸收法和负离子沉降法。过滤法是利用空调、加湿器、空气清新器等吸收颗粒物，虽能明显降低颗粒物的浓度，但是滤膜需要清洗或更换。水吸附法是采用超声雾化器、室内水帘、水池等产生的雾水吸收空气中的亲水性颗粒物，缺点是增加湿度，憎水性颗粒物不能有效去除。现有除尘装置对超细颗粒物的捕获率极低。The existing removal methods of particulate matter in flue gas mainly include filtration method, water adsorption method, plant absorption method and negative ion precipitation method. The filtration method is to use air conditioners, humidifiers, air fresheners, etc. to absorb particulate matter. Although the concentration of particulate matter can be significantly reduced, the filter membrane needs to be cleaned or replaced. The water adsorption method uses the mist produced by ultrasonic nebulizers, indoor water curtains, pools, etc. to absorb hydrophilic particles in the air. The disadvantage is that the humidity increases, and the hydrophobic particles cannot be effectively removed. The capture rate of ultrafine particles in the existing dust removal device is extremely low.
中国专利文献2011101744180公开的《微细颗粒物的去除方法和去除装置》，CN101869872A公开的《双极荷电强化微细颗粒物聚并装置》，CN102961928A公开的《控制PM2.5细颗粒物的袋式除尘装置》都是通过电凝聚技术使细颗粒物聚合成较大颗粒再去除，结构复杂、耗能高。Chinese patent document 2011101744180 discloses "removal method and device for fine particles", CN101869872A discloses "bipolar charge-enhanced fine particle aggregation device", and CN102961928A discloses "bag-type dust removal device for controlling PM2.5 fine particles" all It uses electrocoagulation technology to aggregate fine particles into larger particles and then removes them, which has a complex structure and high energy consumption.

The upper end of the vertical partition 4 is connected to the top of the housing 1 , and the lower end of the vertical partition 4 is spaced from the bottom of the housing 1 so that the smoke exhaust chamber 5 communicates with the spray adsorption chamber 13 . The top of the housing 1 is provided with a flue gas inlet 3 corresponding to the spray adsorption chamber 13, and an air outlet 2 is arranged corresponding to the smoke exhaust chamber 5. In order to make the flue gas be discharged smoothly, an induced draft fan (not shown in the figure) can be arranged at the air outlet 2. out). The bottom side of the housing 1 is provided with a sewage outlet 7, and the sewage outlet 7 is provided with a sewage valve (not shown in the figure).
喷淋吸附腔13内自上至下设置有多层伞盖单元，每层伞盖单元包括支架10和伞形盖11，支架10上至少设置一个伞形盖11，相邻伞形盖11之间设置有缝隙，外侧伞形盖11与壳体1侧壁之间也设置有缝隙。上层伞盖单元伞形盖之间的缝隙与下层伞盖单元伞形盖之间的缝隙是错开的(上下不重合)。壳体1内底部与最上一层伞盖单元上方之间设置有循环液管8，循环液管8上连接循环泵9。循环液管8的上部伸入壳体1内，并对应最上一层伞盖单元的每个伞形盖11设置一个喷头12，喷头12位于伞形盖11的正上方。The spray adsorption chamber 13 is provided with a multi-layer umbrella cover unit from top to bottom, each layer of umbrella cover unit includes a support 10 and an umbrella cover 11, at least one umbrella cover 11 is arranged on the support 10, and between adjacent umbrella covers 11 There is a gap between them, and there is also a gap between the outer umbrella cover 11 and the side wall of the housing 1 . The slit between the umbrella-shaped covers of the upper layer umbrella cover unit and the slit between the umbrella-shaped covers of the umbrella cover unit of the lower floor are staggered (up and down do not overlap). A circulating liquid pipe 8 is arranged between the inner bottom of the casing 1 and the uppermost layer of the umbrella cover unit, and the circulating liquid pipe 8 is connected with a circulating pump 9 . The upper part of the circulating liquid pipe 8 extends into the housing 1, and a shower head 12 is arranged corresponding to each umbrella cover 11 of the uppermost umbrella cover unit, and the shower head 12 is positioned directly above the umbrella cover 11.
排烟腔5内间隔设置有多层超细纤维填料层6，超细化学纤维的直径选为0.2μm-5μm。Multiple layers of superfine fiber filler layers 6 are arranged at intervals in the smoke exhaust chamber 5, and the diameter of the superfine chemical fibers is selected as 0.2 μm-5 μm.
先通过排污口7向壳体1内注入吸收液(一般为石灰水)，吸收液通过循环泵9由循环液管8上部的喷头12喷下，同时烟气由烟气进口进入喷淋吸附腔13。烟气和喷头12喷淋的吸收液都通过伞形盖11向下运行，在伞形盖11上烟气和吸收液散开，形成瀑布式流动，使得两者充分混合，烟气中的污染物充分被吸收液吸收。同时烟气和吸收液在伞形盖11之间的缝隙落下时进一步混合吸附。经过多层伞盖单元后，绝大部分污染物被吸收液吸附。吸收液与烟气反应后直接落入壳体1的底部，循环使用。First inject the absorption liquid (usually lime water) into the shell 1 through the sewage outlet 7, and the absorption liquid is sprayed down by the nozzle 12 on the upper part of the circulation liquid pipe 8 through the circulation pump 9, and at the same time, the flue gas enters the spray adsorption chamber from the flue gas inlet 13. Both the flue gas and the absorption liquid sprayed by the nozzle 12 run downward through the umbrella cover 11. On the umbrella cover 11, the smoke gas and the absorption liquid disperse to form a waterfall flow, so that the two are fully mixed, and the pollution in the flue gas The substance is fully absorbed by the absorption liquid. Simultaneously, the flue gas and the absorption liquid are further mixed and adsorbed when they fall in the gap between the umbrella covers 11 . After passing through the multi-layer canopy unit, most of the pollutants are absorbed by the absorbent. After the absorption liquid reacts with the flue gas, it directly falls to the bottom of the housing 1 for recycling.
在出气口2处引风机的作用下，经过喷淋吸附的烟气进入排烟腔5，经过排烟腔5内多层超细纤维填料层6再次吸附，最后由出气口2排出。Under the action of the induced draft fan at the air outlet 2, the smoke absorbed by spraying enters the smoke exhaust chamber 5, is absorbed again by the multi-layer microfiber packing layer 6 in the smoke exhaust chamber 5, and finally is discharged from the air outlet 2.
当壳体1底部的吸收液净化能力下降后，通过排污口7排出进行更换。When the purification ability of the absorption liquid at the bottom of the housing 1 decreases, it is discharged through the sewage outlet 7 for replacement.
