Description

一种畜禽养殖场臭气烟气治理系统及方法 技术领域
本发明属于污染治理技术领域,具体涉及一种畜禽养殖场臭气烟气治理系统及方法,所述发酵臭气是指畜禽养殖场畜禽粪便发酵产生的臭气,以及病死畜禽动物、胎盘、生活垃圾和秸秆等农村有机废弃污染物燃烧以及石化燃料燃烧产生的烟气。
背景技术
畜禽养殖场畜禽粪便在发酵堆肥过程中,在有氧或缺氧条件下,物料中的有机成分如蛋白质等被微生物的分解,产生大量有毒有害的臭味气体,这些臭气若不加以处理,直接排放到大气,将严重影响堆肥厂及其周边的大气环境。因此,堆肥过程中的除臭工程成为有机固体废弃物高温堆肥过程不可或缺的一部分。
在畜禽粪便发酵过程中,微生物通过代谢活动,把其中一部分有机物氧化成简单的无机物,为生物生命活动提供所需的能量,另一部分有机物转化为生物体所需的营养物质,形成新的细胞体,使微生物不断增殖,在此过程中,放出大量能量,除小部分为细胞质合成提供能量外,其余均以热量的形式放出,据文献介绍,畜禽粪便在高温发酵阶段,微生物氧化分解有机废弃物平产生的热量约420kJ/kg,这些热能随臭气排出,使臭气温度最高可达60~70℃,同时,由于物料堆体温度升高,导致物料水分蒸发速度加快,大量水分也随臭气排出。
在畜禽粪便进行反应器发酵堆肥过程中,为了提高发酵效率,缩短堆肥时间,提升有机肥质量,常设置热源对反应器进行加热,如煤炭、柴油和生物质燃料等燃烧,但这些热源在燃烧过程中产生的烟气不仅含有烟尘等颗粒物、一氧化碳(CO)、二氧化硫(SO2)和氮氧化物(NOx)等有毒有害气体,而且烟气中含有大量热量,使烟气温度高达200℃;目前,高温焚烧是病死畜禽动物无害化处理的一种方法,但由于病死畜禽动物中有机质(如蛋白质和脂肪)含量高,焚烧产生大量的烟气,这些烟气中含有大量热量,以及未完全燃烧的产生的颗粒物(烟尘)和酸性气体(NOX、SO2等);又由于地域分散,农村生活垃圾的处理成本太高,一般被人们随意倾倒和焚烧,焚烧过程中产生大量的烟气,这些烟气不仅含有大量的颗粒物(烟尘)和酸性气体(CO、NOX、SO2、HCl等)等,也含有大量的热量。这些臭气和烟气的直接排气造成严重的空气、环境污染,产生酸雨、温室效应和雾霾等一系列环境问题,对人类的生产、生活产生极大地负面影响。
治理臭气和燃烧烟气的技术有很多,如吸收吸附、焚烧法、化学转化法、冷凝法及生物法等,但在这些方法中,最为经济有效的是生物除臭法,生物除臭法是一种无臭化、无害化的工艺方法,即利用具有除臭功能的微生物菌群转化废气中的硫化氢、还原硫化物等臭气物质,具有去除率高,运转费用低,操作管理简单,不产生二次污染等优点,但是,生物除臭法除臭效果依赖除臭微生物的活性,除臭进气温度过高或过低都会影响微生物的生长繁殖,进而降低除臭效果,当除臭进气温度高于40℃或低于15℃时,除臭微生 物生长繁殖受到抑制;当除臭进气温度高于60℃时,除臭微生物大量死亡,丧失除臭效果。

有益效果:
畜禽粪尿、病死畜禽动物、胎盘、生活垃圾和秸秆等农村有机废弃污染物是农村环境污染的重要污染源,本发明不仅能治理畜禽粪尿在高温发酵过程中产生的臭气,而且还能治理病死畜禽动物、胎盘、生活垃圾和秸秆等农村有机废弃污染物,以及石化燃料在燃烧过程中产生的烟气,为农村环境污染治理做出重要贡献。
本发明充分考虑畜禽粪尿发酵臭气热量高、湿度大的特点,创造性地设计一种臭气换热冷凝器,换热冷凝器内均匀竖直排列中若干个换热管,换热管内含热臭气与管外的新鲜空气对流,通过换热管进行充分地热交换,该方式与传统换热方式相比,换热比表面积大,换热效率高,同时,新鲜空气经换热冷凝器加热成热空气,热空气可以作为畜禽粪尿高温好氧发酵的热源,对畜禽粪尿进行加热、供氧,缩短畜禽粪尿发酵升温时间,提高发酵效率。
由于畜禽粪尿发酵臭气湿度大,在经换热冷凝器降温的同时,也产生了大量大量冷凝水,这些冷凝水经换热管自然汇集到换热冷凝器的下端盖内,当冷凝水液位达到一定高度时,由于压差的作用,冷凝水随U型管自然外排至沟渠中,这种方式操作简单易行,同时利用冷凝水密封下端盖冷凝水排水口,防止冷凝后的臭气经下端盖冷凝水排水口排向大气造成二次污染。
化石燃料,以及病死畜禽动物、胎盘、生活垃圾和秸秆等农村有机废弃污染物在多功能生物质燃烧锅 炉燃烧产生的烟气中含有大量的热量,但由于病死畜禽动物、胎盘、生活垃圾和秸秆等农村有机废弃污染物在多功能生物质燃烧锅炉燃烧产生的烟气中含有大量的,易使曝气头堵塞的颗粒物,故当上述农村有机废弃污染物在多功能生物质燃烧锅炉燃烧时,产生的烟气不直接对液体发酵反应器进行曝气,而是采用洗涤塔洗涤,将燃烧烟气和粪尿液体同时送入洗涤塔内进行换热、换质,使烟气降低的同时,畜禽粪尿液体的温度升高,多功能生物质燃烧锅炉在燃烧过程中产生的烟气中含有大量的,如二氧化硫、三氧化硫、一氧化氮和二氧化氮等酸性气体与畜禽粪尿液体中的水分子结合,释放出H+,降低畜禽粪尿液体的pH,减少氨气的释放,降低畜禽粪尿液体减少营养元素的损失。多功能生物质燃烧锅炉在燃烧过程中产生的烟气中含有大量如PM2.5等微小颗粒物,这些颗粒物能被畜禽粪尿液体吸收,部分转化成为有益的养分。
当在冬季进行畜禽粪尿的高温好氧发酵,以及高温好氧发酵伊始,排出的臭气温度低时,无需换热冷凝,本发明创新设计,在换热冷凝器管路上设置旁通支路,当在冬季进行畜禽粪尿的高温好氧发酵,以及高温好氧发酵伊始,排出的臭气温度低时,低温臭气经过旁通支路进入生物除臭滤塔,以避免低温臭气经过换热冷凝器再次降温;而当在畜禽粪尿的高温好氧发酵的高温阶段,排出的臭气温度高、湿度大,此时关闭旁通支路,臭气通过换热冷凝器降温,使生物除臭滤塔内物料温度始终保持在限定的范围内,既保证除臭效果,又使生物除臭滤塔中的微生物不至于休眠和死亡。
本发明既节能,又环保,真正实现污染治理与能源循环利用的和谐统一。
