Description
技术领域 technical field
本实用新型涉及一种两段式发酵罐，属于生物发酵技术领域。 The utility model relates to a two-stage fermentation tank, which belongs to the technical field of biological fermentation.
背景技术 Background technique
目前，我国所建设的沼气工程主要是利用锅炉、阳光棚、发电机 余热和太阳能增温管来给厌氧发酵罐增温，众所周知，沼气工程运行产甲烷所需要发酵温度要求在35-65 度，特别是北方冬季严寒低温，锅炉增温费用过高，环保政策也限制使用，造成沼气工程无法运行生产沼气，沼气发电机无沼气供燃停止发电，无余热产生；此外北方冬季气温低太阳能增温管冻坏严重，无法保证厌氧发酵罐所需要的增温要求；因此，研究开发能在北方地区冬季正常运行的厌氧发酵罐，是急需解决的课题。 At present, the biogas projects built in China mainly use boilers, sun sheds, waste heat from generators and solar heating tubes to increase the temperature of anaerobic fermentation tanks. As we all know, the fermentation temperature required for methane production in biogas projects is required to be 35-65 degrees , especially the cold and low temperature in winter in the north, the high cost of boiler heating, and the environmental protection policy also restricts the use, resulting in the inability of biogas projects to produce biogas. The temperature pipes were seriously damaged by freezing, and the temperature increase required by the anaerobic fermentation tank could not be guaranteed; therefore, research and development of anaerobic fermentation tanks that can operate normally in winter in northern regions is an urgent problem to be solved.
同时，发酵装置是微生物在发酵过程中生长繁殖和行成产品的外部环境装置，需要在密闭环境中进行，这样操作人员对内部气压不易监控，气压过大或者气压过小都会给发酵过程带来危险，而且在发酵的过程需要在一定范围的温度进行，以促进微生物的生长，在传统的发酵罐内，没有温度检测装置，不利于发酵的过程的控制，给发酵过程带来不便。 At the same time, the fermentation device is an external environmental device for the growth and reproduction of microorganisms and the production of products during the fermentation process. It needs to be carried out in a closed environment, so that it is difficult for the operator to monitor the internal air pressure. It is dangerous, and the fermentation process needs to be carried out at a certain temperature to promote the growth of microorganisms. In the traditional fermentation tank, there is no temperature detection device, which is not conducive to the control of the fermentation process and brings inconvenience to the fermentation process.
