Description
本发明属于生物电厂灰的处理与利用技术领域,尤其涉及一种以生物质电厂灰制备的新型肥料及其生产方法。
现代人们利用农作物和植物,被搬离所生长的土地,营养成分没有归还回去,导致土壤成分缺失,农作物产量下降。肥料是农作物生长的必要条件。为了增产,人为添加化肥,由于养分单一,而且含化学成分,虽然个别养分高,但容易挥发或者随水渗入地下,造成水质污染,土壤板结,肥效不持久。近些年来发展的一些新型复合肥,相比化肥更加科学合理。为了延缓养成分释放,提高肥效持久性,发明了缓控复合肥,其利用一些膜技术延缓肥料释放速度,但是包膜材料价格昂贵,增加肥料成本。此外,无论传统化肥还是目前的新型复合肥料,成分都是人工添加,目前人工还无法做到植物需要元素的准确添加量。
本发明要解决的技术问题是:提供一种利用生物质电厂灰制备的新型肥料及其生产方法。该新型肥料具有缓慢释放养分作用,而且成分更绿色、搭配更科学合理。
本发明为解决上述技术问题所采取的技术方案为:
一种新型肥料,其特征在于,它包括生物质电厂灰及粘结剂,所述生物质电厂灰由鸡粪、稻壳、毛竹、及薪材燃烧所得,所述鸡粪、稻壳、毛竹、及薪材的质量比为30-50:10-40:2-20:10-30,所述生物质电厂灰与粘结剂的质量比为300-990:10-30。
上述方案中,所述生物质电厂灰的化学成分包括15%-16%的K2O,16%-17%的P2O5,26%-27%的SiO2,2%-3%的有机质。
上述方案中,所述新型肥料还包括添加剂。
上述方案中,所述生物质电厂灰、粘结剂、与添加剂的质量比为300-990:10-30:200-350。
上述方案中,所述添加剂为味精厂排污淤泥、玉米浆、或猪粪。
上述方案中,所述味精厂排污淤泥的水含量10% ~ 20%。
一种新型肥料的生产方法,其特征在于,它包括以下步骤:按照生物质电厂灰与粘结剂的质量比为300-990:10-30将生物质电厂灰与粘结剂置于造粒机中,加入水充分搅拌均匀,然后将产物经过干燥粉碎、除尘、冷却后得到颗粒状新型肥料,所述生物质电厂灰由鸡粪、稻壳、毛竹、及薪材燃烧所得,所述鸡粪、稻壳、毛竹、及薪材的质量比为30-50:10-40:2-20:10-30。。
上述方案中,还包括在加水充分搅拌均匀后,进行堆制反应的步骤。
本发明的原理为:
1)由于生物质电厂燃烧薪柴、农作物,除氮、硫、碳被烧失掉外,其他元素留在灰中,成分比例跟植物所需要一致。在电厂灰中补充硫和氮,以及有机物可制备出不同种类的复合肥料。
2)同时,生物质电厂燃烧灰由于高温反应,得到许多类似多孔结构,营养元素贮藏在里面,具有缓慢释放养分作用。生物质电厂灰形成多孔的微观结构原因主要有两个:一个是毛竹、稻壳由许多微孔组成,充当骨架作用,当这几种燃料混合在高温燃烧时,就形成多孔结构;另一个原因是鸡粪内含有磷钾硅钙等无机物和有机物,在电厂锅炉内高温反应,跟天然沸石分子筛形成机理类似,形成多孔的微观结构。
3)由于鸡粪内含磷和钾的量较高,薪柴中一些草木含钾的量也较高,这些物质在燃烧后,造成生物质电厂灰含钾在10%以上,磷在12%以上。
本发明的新型肥料优点在于:取之于田,用之于田,不破坏土壤元素平衡,不带来激素和病菌,肥效长久,不污染环境。古人很早就焚烧植被,使用牲畜粪便作为田庄的养分,这些天然肥料,养分搭配合理,肥效长久。生物质电厂灰的原料来自植物和鸡粪,燃烧后不仅除去里面的病菌、激素,又形成与目前市场缓控复合肥结构一样的多孔结构,并且里面的养分来自自然界,不造成环境污染;另外里面成分中一部分养分为可溶性,养分释放速度比有机肥快。

图2为图1的放大图。
图3为本发明的生物质电厂灰的X光量子能谱(EDX)图。
图4为本发明的生物质电厂灰的傅里叶红外光谱图。
下面结合附图和实施例对本发明作进一步的描述,当然下述实施例不应理解为对本发明的限制。

对本实施例的生物质电厂灰的钾和磷的存在形式进行如下分析:
1)钾:钾存在形式有两类,可溶性钾和不可溶性钾。经试验验证:生物质电厂灰约10%溶于水,将溶于水的这10%的生物质电厂灰干燥蒸发后得到白色粉末,该白色粉末中含钾51.07%(以K2O标定),以KCl和K2SO4形式存在,还同时含有少量钠、钙和镁盐,不含磷;
2)磷:将不溶于水的90%的电厂灰中加入质量浓度为20%的盐酸反复浸泡,有55%溶解,仍有35%不溶解。溶解部分为含磷矿物,不溶于水,溶于酸,以磷酸钙、钾钙镁磷复盐形式存在。利用扫描电镜及电子能谱(EDX)测试其不溶解部分主要为SiO2。
