无阀滤池

重力式无阀滤池具有无大型阀门、正水头过滤、冲洗自动化、造价低及操作管理方便等优点，被广泛应用于地表水净化、景观水净化、河湖水净化、地下水除铁除锰、自来水厂、工业循环水旁流过滤、生产废水除悬浮杂质、有机污水经生化处理和二次沉淀池处理之后的后续过滤以及室内游泳池水的过滤，等多种工、农业水体净化领域。 
The gravity valveless filter has advantages such as no large valves, positive-head filtration, automated backwashing, low manufacturing cost and easy operation. It is widely used in industrial and agricultural water purification fields, including surface water purification, landscape water purification, lake/river water purification, groundwater iron/manganese removal, waterworks, industrial circulating water side-stream filtration, production wastewater suspended impurity removal, post-filtration of organic wastewater after biochemical treatment and secondary sedimentation, and indoor swimming pool water filtration.

据我司多年生产经验，不断更新完善，研制出了 MLF 系列改进型重力式无阀过滤器。 该设备的更新完善，具备了更宽广的处理能力和适用范围，常规处理范围有每小时处理20T、40T、60T、80T、100T、150T、200T、300T等多个规格。 另外可根据用户不同要求设计制造各个规格的单、多罐式重力式无阀过滤器。 
Based on years of production experience and continuous improvement, the company has developed the MLF series improved gravity valveless filter. This upgraded and improved equipment features expanded processing capacities and broader applicability, offering standard treatment capacities of 20T, 40T, 60T, 80T, 100T, 150T, 200T, and 300T per hour. In addition, customized single-tank or multi-tank gravity valveless filters in various specifications can also be manufactured to meet specific user requirements.

原水经分配水箱进入过滤器，自上而下地过滤。 由于滤层不断截留进水中的悬浮物，滤层的水头损失逐渐增加，使得虹吸上升，管冲中的水位上升。 当水位上升进入虹吸辅助管内的水射器时，由于水力作用将虹管内的空气带走，形成负压。 当负压到达设计值时，便发生虹吸现象，此时水箱中的水自下而上地反洗而得以“再生”。 由于不断反洗滤层，水箱中水位下降至规定值时，虹吸作用被破坏，反洗结束，过滤装置又重新开始工作。 
Raw water enters the filter through a distribution tank for downward filtration. As the filter bed continuously traps suspended solids from the influent water, the head loss across the filter bed gradually increases, causing the water level in the siphon riser tube to rise. When the rising water reaches the water ejector in the siphon auxiliary tube, hydraulic action removes air from the siphon, creating negative pressure. When the negative pressure reaches the design value, siphon effect occurs, allowing water from the tank to backwash from bottom to top, thereby realizing "regeneration". As the filter bed is continuously backwashed, the water level in the tank drops to the specified value, breaking the siphon effect and ending the backwashing process, and then the filtration unit resumes operation.
