Description
Technical Field
The utility model relates to a sewage treatment technical field relates to a sandstone filtration ware, especially relates to a sandstone filtration ware's water-locator.
Background
The sand filter is one of the sewage treatment tools, and the water distributor of the sand filter influences the sewage treatment effect. The water distributors can be divided into point water distributors, line water distributors and surface water distributors according to different flow modes. Although the point water distributor is simple in design and processing of water distribution holes, the point water distributor is limited by the number of the holes, large-scale uniform water distribution is difficult to realize, and the point water distributor is large in local resistance loss and high in energy consumption. The line water distributor is divided into a linear water distributor and a curved water distributor. Compared with a point water distributor, the linear water distributor has a large water distribution range, can meet the requirement of uniform water distribution along the length direction of a pipe, and is represented by a porous pipe. But the water distribution uniformity of the linear water distributor in the direction vertical to the pipe is limited; therefore, a novel curve water distributor appears, such as an annular pipe network water distributor, the design and calculation of the novel curve water distributor are more complex as those of a linear water distributor, and certain difficulty is brought to processing and installation; once deviation exists in processing or installation, the uniform water distribution effect of the whole water distributor can be influenced; meanwhile, the closed ring has difficulties in production, installation, overhaul, adjustment and the like; moreover, as a whole, the spraying density (namely the water spraying amount in unit time and unit cross section) at each position is equal to the average value, but the water distribution amount of each point on the cross section is actually unequal; therefore, the circular pipe network water distributor is not optimal. The surface water distributor is greatly improved in the aspect of preventing blockage compared with a point water distributor and a line water distributor, and the calculation, design, production and installation of water distribution holes are convenient; but the water distribution surface is larger, so the low water distribution pressure and insufficient impulse force are the inducement of the short flow of the reactor.
The existing water distributor is easy to block and uneven in water distribution, water is unevenly distributed in the filler in the tank body, and even a short circuit phenomenon occurs. Therefore, the improvement of the structure of the water distributor to prevent blockage and realize uniform water distribution still needs further research.
The chinese patent application No. 201611067823.1 discloses a water distributor for sewage treatment; the water distributor adopts a mosquito-repellent incense type structure and is provided with two spiral water distribution pipes, when the water inlet pipe is started, the inner end and the outer end of each water distribution pipe simultaneously distribute water, the density of a first water outlet hole is gradually increased along with the increase of the spiral opening degree, and the density of a second water outlet hole is gradually reduced along with the increase of the spiral opening degree, so that the uniformity of water distribution is ensured, and the water distribution range is enlarged; however, the distributor is complicated to manufacture and can cause blockage of the distributor.
Chinese patent application No. 201611028220.0 discloses a gravity flow distribution tray. The water distribution plate comprises a plate body and a plate cover, wherein the plate cover is provided with vent holes, the plate body is upwards protruded and is distributed with reticular runners, and the vent holes are distributed at the bottoms of the runners; although the plate body of the water distribution plate realizes uniform water distribution in a certain range, the plate cover limits the water distribution range.
