Abstract
本发明公开一种新型小型气水反冲洗过滤池，包括有一池体，可分为2~6个滤格，每个滤格过滤面积不大于30m2；该滤格设置有进水区、过滤区以及配水配气区，通过本发明人对滤头的优化设计，可有效地防止滤头堵塞，大大地延长滤池的翻修周期；其翻修周期可达5年以上。通过本发明人对池体各个部位的优化设计，可提高反洗效果，节能降耗且能有效防止滤料流失；由于取消V型滤池专用的进水分配槽、堰板和V形槽，只采用进水总管加进水支管的形式向各滤格分配原水，可基本达到均匀进水的要求，简化了池体结构；由于反洗水通过池底配水配气区均布，反洗气则通过池外的配气歧管均布，又进一步简化池体结构，占地缩小，造价降低。
The invention discloses a new type of small air-water backwashing filter tank, which includes a tank body, which can be divided into 2 to 6 filter grids, and the filtration area of each filter grid is not more than 30m2 ; the filter grid is provided with a water inlet area, a filter Area and water and gas distribution area, through the optimal design of the filter head by the inventor, can effectively prevent the filter head from clogging, and greatly prolong the renovation period of the filter tank; the renovation period can reach more than 5 years. Through the optimal design of each part of the tank body by the inventor, the backwashing effect can be improved, energy can be saved and consumption can be reduced, and the loss of filter material can be effectively prevented; due to the cancellation of the special water inlet distribution tank, weir plate and V-shaped tank for the V-shaped filter tank, Only the main water inlet pipe and the water inlet branch pipe are used to distribute raw water to each filter grid, which can basically meet the requirements of uniform water inlet and simplify the structure of the pool body; Then, the gas distribution manifolds outside the pool are evenly distributed, further simplifying the structure of the pool body, reducing the occupied area and reducing the cost.
