Description

一种多级收集浮渣有机垃圾沼气发酵装置A multi-stage biogas fermentation device for collecting scum and organic waste

技术领域technical field

本实用新型属于沼气发酵技术领域,涉及一种多级收集浮渣有机垃圾沼气发酵装置。The utility model belongs to the technical field of biogas fermentation, and relates to a multistage biogas fermentation device for collecting scum and organic garbage.

背景技术Background technique

随着经济的发展,城市规模的迅速扩大和城市人口的快速增加,产生的有机垃圾越来越多。有机垃圾中水分和有机物含量高,容易分解,容易产生臭气和污水等。如果不及时处理,将对环境造成二次污染,并且有机垃圾长时间堆积在一起,容易滋生病原微生物、霉菌毒素等有害物质。目前有机垃圾处理方法主要有卫生填埋、饲料加工、好氧堆肥、提炼生物柴油和厌氧消化等。而目前的厌氧消化装置在厌氧消化过程中容易出现部分发酵原料在浮力的作用下,上浮形成浮渣。浮渣长期缺水、干缩进而形成结壳。结壳可导致厌氧消化装置产生的沼气聚集受阻,有效发酵容积和储气室容积减少,原料利用率降低,产气率减少等。严重时会导致厌氧消化装置的爆裂。因此,有必要研制一种能有效解决厌氧消化装置在厌氧消化过程中出现浮渣问题,使得有机垃圾得以充分厌氧消化,实现最大资源化处理,从而提高原料的利用率和提高产气率。With the development of economy, the rapid expansion of city scale and the rapid increase of urban population, more and more organic wastes are produced. Organic waste contains high moisture and organic matter content, which is easy to decompose, and it is easy to produce odor and sewage. If it is not treated in time, it will cause secondary pollution to the environment, and organic waste will accumulate for a long time, which will easily breed harmful substances such as pathogenic microorganisms and mycotoxins. At present, the treatment methods of organic waste mainly include sanitary landfill, feed processing, aerobic composting, extraction of biodiesel and anaerobic digestion. However, during the anaerobic digestion process of the current anaerobic digestion device, it is easy for some fermentation raw materials to float up to form scum under the action of buoyancy. The scum is short of water for a long time, dries up and shrinks to form crusts. The incrustation can lead to the blockage of the accumulation of biogas produced by the anaerobic digestion unit, the reduction of the effective fermentation volume and the volume of the gas storage chamber, the reduction of the utilization rate of raw materials, and the reduction of the gas production rate. In severe cases, the anaerobic digestion unit will burst. Therefore, it is necessary to develop a method that can effectively solve the scum problem in the anaerobic digestion process of the anaerobic digestion device, so that the organic waste can be fully anaerobicly digested, and the maximum resource treatment can be realized, thereby improving the utilization rate of raw materials and increasing the gas production. Rate.

本实用新型的工作原理如下:The working principle of the utility model is as follows:

使用本实用新型多级收集浮渣有机垃圾沼气发酵装置前,首先关闭投料桶清理阀4、储气室沼液清洗阀8、沼液滤清液溢流阀18和发酵室清理阀26。打开投料桶的沼液回流稀释阀6、发酵室进料阀23和贮液箱沼液阀31。按照常规程序,将日常收集到的有机垃圾投放到投料桶5里,启动污水泵32将贮液箱29里的沼液滤清液通过回流管路33抽至投料桶5里和投放的有机垃圾混合好,并使用投料桶5上的沼液回流稀释阀6调节好滤清液的流量。启动有机垃圾粉碎机2将有机垃圾和沼液滤清液的混合物粉碎好。在有机垃圾粉碎机2产生压力的作用下,粉碎好的有机垃圾混合物依次经过有机垃圾粉碎机2的出料口3、发酵室进料阀23和发酵室进料口24进入到有机垃圾发酵罐的发酵室27里。在有机垃圾发酵罐的发酵室27里,粉碎好的有机垃圾混合物在合适的温度下厌氧发酵产生沼气,沼气上升进入到储气室12里,并通过沼气输出管13输送给用户使用。有机垃圾混合物在有机垃圾发酵罐的发酵室27里厌氧消化过程中容易出现部分发酵原料在浮力的作用下上浮形成浮渣。浮渣在上浮过程中受到有机垃圾发酵罐内设置的一级浮渣收集罩座21和一级浮渣收集罩20的阻挡,改变了上浮方向并向一级浮渣提升管19中央聚集,并沿一级浮渣提升管19向上提升直到储气室12。而产生的沼气、沼液以及部分浮渣则通过一级浮渣收集罩20上的小孔继续上升。上升到二级浮渣收集罩16时,又受到二级浮渣收集罩16的阻挡,沼气、沼液继续通过二级浮渣收集罩16上的小孔上升。而通过一级浮渣收集罩20的浮渣再次被二级浮渣收集罩16收集,并沿二级浮渣提升管15向上提升直到储气室12。通过二级浮渣收集罩16的沼气、沼液以及部分少量浮渣继续上升。上升到多孔挡渣板11时,再次受到多孔挡渣板11的阻挡,沼气、沼液则通过多孔挡渣板11的小孔顺利进入到储气室12里。部分少量浮渣则被挡在多孔挡渣板11的下面。沼气通过沼气输出管13输送给用户使用。经过多级分离以后的沼液滤清液在沼液滤清液溢流阀18的控制下,经沼液滤清液出口17和溢流管22流到贮液设备的贮液箱29贮存使用。经一级浮渣收集罩20和二级浮渣收集罩16收集,并经一级浮渣提升管19和二级浮渣提升管15提升到储气室12的浮渣需要清洗回流时,先关闭投料桶5的沼液回流稀释阀6,启动污水泵32,再打开储气室沼液清洗阀8将贮液箱29里的沼液滤清液通过回流管路33抽至沼液环型喷洒管10。通过沼液环型喷洒管10上开设的喷洒孔将沼液滤清液喷洒在浮渣表面,并将浮渣打碎。打碎后的浮渣和沼液滤清液混合物经浮渣回流管25回流到发酵室27底部,并和新的发酵原料一起混合,重新发酵产气。清洗浮渣完毕以后,必须马上关闭储气室沼液清洗阀8。需要清洗投料桶5时,可关闭发酵室进料阀23,用水清洗投料桶5,打开投料桶清理阀4,将水排出投料桶5外。当发酵室27里沉渣过多时,必须要适当清理,打开发酵室清理阀26,将发酵室27里的沉渣排出,排出的沉渣要用专用容器装好,用做肥料,不可到处排放,以免造成二次污染。排放合适以后,立即把发酵室清理阀26关闭好。Before using the biogas fermentation device for multi-stage collection of scum and organic waste of the utility model, firstly close the feeding barrel cleaning valve 4, the biogas slurry cleaning valve 8 of the gas storage chamber, the biogas slurry filtrate overflow valve 18 and the fermentation room cleaning valve 26. Open the biogas slurry reflux dilution valve 6 of the feeding bucket, the feed valve 23 of the fermentation chamber and the biogas slurry valve 31 of the liquid storage tank. According to the routine procedure, put the organic waste collected daily into the feeding bucket 5, start the sewage pump 32 to pump the biogas slurry filtrate in the liquid storage tank 29 through the return line 33 to the feeding bucket 5 and put in the organic garbage. Mix well, and use the biogas slurry return dilution valve 6 on the feeding bucket 5 to adjust the flow rate of the filtrate. Start the organic waste pulverizer 2 to pulverize the mixture of organic waste and biogas slurry filtrate. Under the action of the pressure generated by the organic waste pulverizer 2, the pulverized organic waste mixture enters the organic waste fermenter through the discharge port 3 of the organic waste pulverizer 2, the feed valve 23 of the fermentation chamber and the feed port 24 of the fermentation chamber in sequence. The fermentation room is 27 miles. In the fermentation chamber 27 of the organic waste fermentation tank, the pulverized organic waste mixture is anaerobically fermented at a suitable temperature to produce biogas.

During the floating process, the scum is blocked by the primary scum collection cover seat 21 and the primary scum collection cover 20 provided in the organic waste fermenter, changing the direction of flotation and gathering towards the center of the primary scum riser 19, and Lift upwards along the primary scum riser 19 until the air storage chamber 12.

When rising to the secondary scum collecting cover 16, it is blocked by the secondary scum collecting cover 16 again, and biogas and biogas slurry continue to rise through the apertures on the secondary scum collecting cover 16. The scum passing through the primary scum collecting cover 20 is collected by the secondary scum collecting cover 16 again, and is lifted up along the secondary scum riser 15 until the air storage chamber 12 . The biogas, biogas slurry and part of a small amount of scum that pass through the secondary scum collecting cover 16 continue to rise. When it rises to the porous slag retaining plate 11, it is blocked by the porous slag retaining plate 11 again, and biogas and biogas liquid then enter into the gas storage chamber 12 li smoothly through the apertures of the porous slag retaining plate 11. Part of a small amount of scum is blocked under the porous slag retaining plate 11 . The biogas is transported to users through the biogas output pipe 13 . Under the control of the biogas slurry filtrate overflow valve 18, the biogas slurry filtrate after multi-stage separation flows to the liquid storage tank 29 of the liquid storage equipment through the biogas slurry filtrate outlet 17 and the overflow pipe 22 for storage and use .
