Description
Technical Field
The utility model relates to the field of resource utilization, in particular to an on-line cleaning device for tank sediments.
Background
Due to the complexity of urban organic solid wastes and agricultural wastes and various uncontrollable factors (such as equipment abrasion, misoperation and the like) in a pretreatment link, the slurry entering the anaerobic fermentation system after pretreatment contains a certain amount of sandstone, and the specific content of the sandstone is related to the impurity removal efficiency of the pretreatment system and the total amount of impurities contained in raw materials. At present, the anaerobic fermentation tank mostly adopts mechanical stirring. All forms of mechanical agitation present a relatively dead zone of agitation, i.e., what we generally refer to as a region of low flow velocity in the flow field. The sand in the slurry enters the flow field in the tank along with the stirring of the stirrer, but most of the sand, especially the sand with larger particle size and larger density, can gradually precipitate in the area with weaker flow field in the tank. The large-particle heavy substances mainly comprise gravels which are not completely removed in pretreatment, broken glass slag, ceramic slag, seed shells which cannot be digested by anaerobic fermentation, bamboo and wood particles and the like, and the particle size is generally in the range of 1-15 mm. Meanwhile, organic matters in the slurry are degraded in a large amount after entering an anaerobic system, the TS content and viscosity of the slurry in the anaerobic system are greatly reduced, and small-particle-size sand stones are precipitated, so that tank body precipitates are formed;
along with the operation of the project, if the sediment of the anaerobic tank is not cleared in time, the sediment brings harm to the operation of the whole project, firstly, the effective volume of the tank body is reduced along with the gradual silkworm feeding of the sediment in the internal space of the anaerobic fermentation tank, so that the treatment capacity of the anaerobic tank is reduced, the acidification risk of the tank body is increased, and the rear-end sewage treatment pressure is increased; in the process of gradually increasing the height of sediments in the tank, instruments (such as a thermometer, a liquid level meter and the like) and valves in the tank can be covered by the sediments to influence the realization of the normal function of equipment, and meanwhile, the stirring resistance of a stirrer in the fermentation tank can be continuously increased, the stirrer can be broken when the stirring resistance is serious, and the basic flatness of the tank and the safety of the tank can be directly influenced.
Therefore, the accumulation of the sediment at the bottom of the tank seriously influences the normal operation of the organic garbage anaerobic fermentation system, and reasonable and effective measures must be taken to reduce the influence to the minimum. At present, most of continuous fermentation biogas projects regularly and integrally clean the reactor to discharge accumulated sand in the actual operation process, consume a large amount of manpower and material resources, require a large amount of time to restart the fermentation system, and seriously affect the normal operation of the project. At present, with the continuous increase of the operation time of a biogas project, tank bottom sediments of a large batch of anaerobic reactors are accumulated to different degrees. The cost brought by stopping production and cleaning the tanks is too high, so that a large number of reaction tanks are in a faulty running state. Therefore, the running anaerobic fermentation tank is provided with an online tank-outside continuous desanding technology, and tank bottom sediments are directly removed from the running process, so that the harm caused by the existing anaerobic tank sediments is greatly reduced, and the tank cleaning period is prolonged.
