Description

Technical Field

[0001] The utility model relates to the technical field of ozone catalytic oxidation process, in particular to a water distribution device for ozone catalytic oxidation process. Background Art

[0002] The filter bricks used in traditional ozone catalytic oxidation filters cannot distribute both water and air simultaneously. A stainless steel air pipe must be installed between every set of filter bricks, resulting in numerous underwater steel pipe openings, a large bill of quantities, and a significant risk of failure. Furthermore, water and air are distributed only once, through the gaps between the filter bricks. Water and air cannot escape from the top of the filter bricks, creating a blind spot for backwashing. The filter bricks require complex air manifolds, which is a significant installation effort. Using standard SS304 stainless steel adds additional costs, and the air manifolds are prone to clogging during later operation. Filter bricks from other manufacturers are constructed of lightweight materials, requiring a secondary pour of concrete within the filter bricks before installation. Furthermore, these lightweight filter bricks can shift and flip under high-intensity air-water backwash during operation, resulting in a loss of effective water and air distribution. This ultimately necessitates system shutdown, removal of wastewater and filter media, and reinstallation, severely impacting system operation.

[0003] In summary, the utility model designs a water distribution device for an ozone catalytic oxidation process having the function of simultaneously distributing backwash air and backwash water. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model aims to provide a water distribution device for an ozone catalytic oxidation process, which has a reasonable structural design, high strength, and the function of simultaneously distributing backwash air and backwash water. The entire pool body only requires one air distribution pipe, and the filter bricks discharge water and air from the top, with high water and air distribution density and no dead angles in backwashing. The filter bricks are firmly and securely connected, and are fixed to the bottom of the pool with concrete mortar, preventing the filter bricks from flipping over. The device is maintenance-free for life, has good use effect, and is highly practical.

[0005] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical scheme: a water distribution device for an ozone catalytic oxidation process, comprising a mortar cushion layer, a filter brick layer, a pebble layer and a catalyst layer arranged from bottom to top in a catalytic oxidation tank, the filter brick layer being fixed to the bottom of the catalytic oxidation tank through the mortar cushion layer, the filter brick layer being formed by arranging multiple filter bricks; the filter brick 6 is an S-shaped filter brick.

[0006] Preferably, the filter brick is provided with a secondary compensation cavity.

[0007] Preferably, only one gas distribution pipe is provided in the catalytic oxidation tank.

[0008] The utility model adopts S-type filter brick as water and gas distribution device, and its beneficial effects are as follows:

[0009] 1. It has the function of distributing backwash air and backwash water at the same time. The entire pool body only needs one air distribution pipe. Other filter bricks cannot distribute water and air at the same time. It is necessary to arrange a stainless steel air pipe for every other group of filter bricks. There are many underwater open steel pipes, the bill of quantities is large, and the potential for failure is great.

[0010] 2. It has a two-stage compensation chamber, which can more evenly distribute the air and water during backwashing; while others only have one distribution, which distributes water and air through the gaps between the filter bricks.

[0011] 3. The filter brick discharges water and air from the top, with high water and air distribution density and no dead angle for backwashing. Other filter bricks cannot discharge water and air from the top, resulting in a blind spot for backwashing.

[0012] 4. The filter bricks are firmly connected and fixed to the bottom of the pool with concrete mortar. There is no possibility of the filter bricks flipping over, and they are maintenance-free for life. BRIEF DESCRIPTION OF THE DRAWINGS
