【摘要】：粉碎后的厨余垃圾能否快速、有效地排至室外是衡量厨余垃圾排放系统性能好坏的重要指标。为了防止排水横支管产生淤堵,需要合理地选择存水弯及横支管的敷设方式。通过采用水龙头连续给水模拟实际的厨余垃圾排放情况,研究了存水弯形式、横支管坡度及其拐弯情况对厨余垃圾管道输送性能的影响。结果表明,P型存水弯较S型存水弯更容易导致横支管固体淤积;此外,横支管输送能力受管道坡度和管道拐弯情况的影响都比较明显,但是管道坡度更为显著。为了保障厨余垃圾排放系统的长期安全使用,针对不同存水弯形式和拐弯情况下的横支管最小敷设坡度提出了相关建议。
[Abstract]:It is an important index to measure the performance of kitchen waste discharge system to measure the performance of kitchen waste discharge system. In order to prevent the blockage of horizontal branch pipe of drainage, it can be quickly and effectively discharged out of the kitchen waste after crushing. It is necessary to reasonably select the laying mode of the water storage bend and the horizontal branch pipe. Through the use of continuous water supply from the faucet to simulate the actual situation of kitchen waste discharge, the form of the water storage bend is studied. The influence of the slope of the transverse branch pipe and its bend on the conveying performance of the kitchen waste pipe. The results show that the water storage bend of P type is more likely to cause solid siltation of the horizontal branch pipe than that of the S type. In addition, the transversal branch pipe transport capacity is obviously affected by the slope of pipeline and the bend of pipeline, but the slope of pipeline is more obvious. In order to ensure the long-term safe use of kitchen waste discharge system. Some suggestions are put forward for the minimum slope of the transverse branch pipe under different water storage and bending conditions.

【正文快照】： 随着国家对城市生活垃圾减量化、无害化、资源化的不断重视以及人们生活品质的不断提高,越来越多的厨余垃圾处理器作为一种环保产品而逐渐走进人们的日常生活。厨余垃圾经过粉碎后进人排水管道,极大地提高了厨房排水中悬浮固体及可沉降固体的含量,可能会增大排水横支管堵塞的
