technical field

The utility model relates to the field of environmental protection water supply and drainage, more specifically, it relates to a flushing device suitable for lateral flow inclined plate/inclined tube sedimentation process.

Background technique

In the current water purification process, sedimentation is the core process connecting the previous and the next. On the one hand, the dense and large-grained alum flowers formed in the coagulation process are precipitated to remove the main suspended and colloidal substances in the water body. On the other hand, through its own purification advantages, reduce filtration The turbidity of the influent water in the pool ensures the filtration cycle of the filter.

At present, the high-efficiency sedimentation processes in the water treatment industry are all developed on the basis of the "shallow sedimentation" theory, and gradually develop from upward flow to side flow/horizontal flow. The lateral flow inclined plate sedimentation device is the most typical lateral flow sedimentation and separation process. Through the structure of multi-channel flow diversion and double-channel flow sludge, the treatment load of inclined plate sedimentation is further increased, and the quality of effluent water is guaranteed. However, due to its high-efficiency sedimentation effect, if the water plant does not carry out effective maintenance during actual operation, it is easy to cause particulate matter such as alum flowers to accumulate on the inclined plate, which eventually leads to blockage of the sludge channel and affects the water purification effect. Therefore, it is necessary to wash the horizontal split-type slanting plate sedimentation device frequently to ensure the normal operation of the device. The same mud flushing problem also exists in the side flow inclined plate/incline tube sedimentation separation process.

The flushing of the plate requires many people to flush back and forth on the top surface of the inclined plate/inclined pipe, lacking safety protection measures, the entire flushing process is complicated, inconvenient, and time-consuming, and it is easy to affect the water supply of the water plant. Moreover, the flushing water on the top surface of the wing plate of the inclined plate/inclined tube in the transverse flow cannot reach the second and lower wing plates, and needs to be washed horizontally from the front and rear sides of the inclined plate/inclined tube, which is difficult to complete manually.
