Description
技术领域 technical field
本发明涉及一种沼气的发生装置。The invention relates to a biogas generating device.
背景技术 Background technique
沼气是一种优质、高效、绿色、环保的燃料，替代传统能源的前景非常广阔。但由于沼气池型采用静态发酵工艺，导致发酵间存在“微生物贫乏区”、“发酵盲区”和“料液短路”。农村家用水压式沼气池运行一段时间后，池内原料由于比重不同和自然沉降规律，发酵器内从下至上逐步分为沉淀层、活性层、清液层和浮渣层，造成沼气池“结壳”问题。结壳已成为当前农村水压式沼气池存在的突出问题。多年的检验证明，以人畜粪便为主要发酵原料的沼气池，一年后结壳的厚度为18～25厘米；以杂草稻草为主要发酵原料的沼气池，一年后结壳厚度为25～35厘米。结壳的形成，导致池内产生的沼气集聚受阻，有效容积和贮气室减小，原料利用率降低，产气量减少。结壳严重时，往往会使一座好端端的沼气池变成“病池”、废池。另外，沼气池“结壳”问题也带来清渣出料困难、产气率低和管理不便等技术问题。这些问题严重影响了沼气技术的利用和推广。Biogas is a high-quality, high-efficiency, green and environmentally friendly fuel, and has a very broad prospect of replacing traditional energy sources. However, due to the static fermentation process used in the biogas digester type, there are "microbe-poor areas", "fermentation blind areas" and "feed-liquid short circuits" in the fermentation room. After the rural household hydraulic biogas digesters have been in operation for a period of time, due to the different specific gravity and natural sedimentation of the raw materials in the digester, the fermenter is gradually divided into sediment layer, active layer, clear liquid layer and scum layer from bottom to top, resulting in the "consolidation" of the biogas digester. shell" problem. Incrustation has become a prominent problem in the current rural hydraulic biogas digesters. Years of inspections have proved that for biogas digesters that use human and animal feces as the main fermentation raw material, the thickness of the crust will be 18-25 cm after one year; 35 cm. The formation of crusts will hinder the accumulation of biogas generated in the pond, reduce the effective volume and gas storage chamber, reduce the utilization rate of raw materials, and reduce the gas production. When the incrustation is serious, it will often turn a good biogas digester into a "sick pond" or a waste pond. In addition, the "crust" problem of biogas digesters also brings technical problems such as difficulty in removing slag and discharging materials, low gas production rate and inconvenient management. These problems have seriously affected the utilization and promotion of biogas technology.
为了有效解决沼气发生器内沼气原料分层严重或清渣出料困难等技术难题，中国实用新型专利“沼气池专用抽液破壳泵”(专利号ZL 200520006297.9)，设计了一种沼气池专用抽液破壳泵，它可以通过抽取沼气池的沼液，使沼液沿导管进入沼气池拱顶向下喷射，将沼气池内原料表面的结壳冲破化解。In order to effectively solve technical problems such as serious stratification of biogas raw materials in the biogas generator or difficulty in removing slag and discharging materials, the Chinese utility model patent "special pump for pumping and breaking shells for biogas digesters" (patent number ZL 200520006297.9) designed a special pump for biogas digesters Liquid pumping shell breaking pump, it can pump the biogas slurry from the biogas tank, make the biogas slurry enter the vault of the biogas tank along the conduit and spray downwards, break through and dissolve the crust on the surface of the raw material in the biogas tank.
中国发明专利“全自动沼气池”(申请号200510099750.X)属水压式沼气池，出料间、沉降间由水压间改进而成。当发酵间积蓄沼气时，把部分沼液压往出料间及沉降间，产生水位差，形成沼气压力；沼气用户使用沼气时，压力减小，沼液返回发酵间。这种现象就叫交换反应，交换反应产生的沼液流动是往返流动的。The Chinese invention patent "Full-automatic biogas digester" (application number 200510099750.X) is a hydraulic biogas digester, and the discharge room and settlement room are improved from hydraulic rooms. When the biogas is stored in the fermentation room, part of the biogas hydraulic pressure is sent to the discharge room and the settlement room to generate a water level difference and form a biogas pressure; when the biogas user uses the biogas, the pressure decreases and the biogas liquid returns to the fermentation room. This phenomenon is called exchange reaction, and the flow of biogas slurry produced by exchange reaction flows back and forth.
中国实用新型专利“连续式自排渣沼气发生罐”(专利号200620008635.7)公开了一种连续式自排渣沼气发生罐，它的主体为圆筒型结构，以卧式斜向安装，倾斜度为1∶3-5；罐体的前端底部开有进料口，该开口连接进料通道，罐体的后端也是在底部开口，该开口连出渣通道，出渣通道的上端接入出渣池；在沼气罐的上方接有沼气出气口；另在进料通道的下方位置设一用于与厕所接通预留管。The Chinese utility model patent "continuous self-discharging biogas generating tank" (Patent No. 200620008635.7) discloses a continuous self-discharging biogas generating tank. The ratio is 1:3-5; there is a feeding port at the bottom of the front end of the tank body, which is connected to the feeding channel, and the rear end of the tank body is also opened at the bottom, and the opening is connected to the slag discharge channel, and the upper end of the slag discharge channel is connected to the discharge channel. A slag pond; a biogas outlet is connected above the biogas tank; and a reserved pipe for connecting with the toilet is provided at the lower part of the feed channel.
上述发明专利装置有些解决了沼气原料分层严重的技术问题，有些解决了沼气发生器清渣出料困难的技术难题，但是，还没有一种装置能同时解决沼气发生器内沼气原料分层严重和清渣出料困难这两个技术难题。Some of the above-mentioned patented devices solve the technical problem of serious stratification of biogas raw materials, and some solve the technical problem of difficult slag removal in biogas generators. However, there is no device that can simultaneously solve the problem of serious stratification of biogas raw materials in biogas generators. And the two technical problems of difficult slag discharge.
