Description

用于小型沼气罐的沼气储存循环装置 Biogas storage circulation device for small biogas tanks

技术领域 technical field

本实用新型涉及一种沼气罐利用装置，尤其涉及10m3以下的小沼气罐。The utility model relates to a biogas tank utilization device, in particular to a small biogas tank below 10m3 .

背景技术 Background technique

目前，传统沼气罐存在着以下不足，当沼气充足时往往导致料液在高压气体压力下流出池外，必须及时排气才能解决，排气不及时容易涨坏沼气池，排出的气体又是影响大气环境的有害气体。另外，现有的沼气罐内容易结垢。At present, the traditional biogas tank has the following shortcomings. When the biogas is sufficient, the feed liquid often flows out of the pool under the pressure of high-pressure gas, which must be exhausted in time to solve the problem. Harmful gases in the atmosphere. In addition, the existing biogas tank is prone to fouling.

发明内容 Contents of the invention

本实用新型的目的在于克服现有小型沼气罐存在的不足之处，提供一种结构简单的沼气循环装置。The purpose of the utility model is to overcome the shortcomings of existing small biogas tanks and provide a biogas circulation device with simple structure.

为了达到上述目的，本实用新型采用的技术方案是：在沼气罐上端的出气管上安装单向出气阀、安全排气阀、集水器、储气囊和三通，三通的一个口连接炉灶，三通的另一个口连接循环泵，循环泵出口连接到沼气罐底部。In order to achieve the above purpose, the technical solution adopted by the utility model is: install a one-way outlet valve, a safety exhaust valve, a water collector, an air storage bag and a tee on the gas outlet pipe at the upper end of the biogas tank, and a mouth of the tee is connected to the stove , the other port of the tee is connected to the circulation pump, and the outlet of the circulation pump is connected to the bottom of the biogas tank.

本实用新型的优点是：The utility model has the advantages of:

罐内气压大时，由气囊储存多余液体，在单向阀的作用下不会再向罐内反充，大于一定压力时才从安全排气阀少量排出，通过循环泵使气囊气体从罐底进入，实现气体自动搅拌，防止原料结壳，形成沼气周而复始的良好循环。When the pressure in the tank is high, the excess liquid is stored by the air bag, and it will not be reversely filled into the tank under the action of the one-way valve. When the pressure is greater than a certain pressure, it will be discharged from the safety exhaust valve in a small amount, and the gas in the air bag will be discharged from the bottom of the tank through the circulation pump. Entering, the automatic stirring of the gas is realized, the crusting of the raw materials is prevented, and a good cycle of biogas is formed.
