High-efficiency cyclone water purification system
DAWT·2022-05-09
Introduction
At present, the domestic slag water treatment methods generally use sedimentation tanks, thickeners, ceramic filter brick tanks and other treatment methods, and a few manufacturers use the method of flocculation sedimentation + inclined tube + sand filtration. The above-mentioned processing technologies all have various problems, and are still lacking in processing capability, stable operation and reliability. If the sedimentation tank process is used, the removal rate of suspended solids is low, the effluent quality is poor, the area is large, the cleaning tank is frequent and the workload is large; the concentrator requires low suspended solids content at the inlet, poor effluent quality, and easy clogging of inclined pipes (plates). Manual cleaning, the ash discharge standpipe is easy to block, resulting in poor mud discharge, and frequent pressure and rake accidents; the ceramic filter block covers a large area, requiring manual cleaning and backwashing, frequent cleaning, and high labor intensity; flocculation and sedimentation + Inclined tube + sand filtration process requires low suspended solids content at the entrance and needs to configure a huge pre-sedimentation tank, the inclined tube (plate) is easy to block, the sand filtration load is large, it needs to be backwashed frequently, and the filter layer is easy to harden. The problem with the above-mentioned processes is that the impact load is low. For suspended solids with SS>3000mg/L, especially for ash and slag water with SS>5000mg/L, it cannot be handled normally.
In the treatment of high suspended solids sewage, the high-efficiency cyclone water purification system shows great technical advantages. It does not need to set up a pre-sedimentation tank, and can quickly and continuously and efficiently purify the sewage with SS≤3000mg/L to 5-50mg/L. This technology can treat sewage with SS≤30000mg/L at the highest level, which is the development of high-concentration ash water treatment. A new way has been developed to solve the problem in the reuse of ash and slag water.
System Features
The process flow is short, the failure rate is low, the operation is stable and reliable; the processing capacity is strong, and the efficiency is high. The processing load of the equipment can reach SS≤3000mg/L, and the maximum can reach SS≤30000mg/L; the design load is high, and the wastewater residence time is ≤30min; The pool and clear water pool can be designed as ordinary transition pools to save floor space; the quality of effluent after treatment is good SS=5-50mg/L, which prevents ash from collecting in cooling towers and water seal tanks, and can be reused for furnace sealing; PLC control, high degree of automation, low labor intensity of workers; less sewage discharge from equipment, high sludge concentration, low moisture content; easy operation, long service life of filter media, and backwashing cycle of 0.5-1 month, with significant savings. Water, energy saving and environmental, social and economic benefits; the main body of the equipment is maintenance-free, which reduces the maintenance workload; the operation of the equipment only needs to be upgraded once, which saves the investment in supporting mechanical and electrical equipment and saves power consumption; the equipment adopts the factory production mode, which greatly improves the accuracy of the equipment , quality and aesthetics, improve the quality of water production; the equipment adopts the factory production mode, which can be mass-produced and shortens the construction period.
