进口内回流泵美国阿卡迪亚品牌

进口内回流泵Product Description:

The eddy current oxygen charging damping device includes a reflux pump installed on the wall of the structure between the low-level aerobic tank and the high-level anoxic tank. The water inlet of the reflux pump is located in the aerobic tank, the water outlet of the reflux pump is located in the anoxic tank, and a eddy current damping cover is installed above the water inlet of the reflux pump; The vortex damping cover destroys the shear force of the water in the inlet area of the reflux pump under negative pressure, effectively prevents the generation of vortex, avoids vortex oxygenation, and ensures the normal operation of denitrification in the anoxic area.

进口内回流泵characteristic:

In the upgrading and reconstruction of sewage treatment plants, increasing the internal reflux is often regarded as one of the key points. If it is necessary to increase the internal reflux, an internal reflux pump must be added. The method adopted by most sewage treatment plants is to install a reflux pump and a reflux pipeline on the wall of the originally designed structure wall to reflux the mixture with low dissolved oxygen at the end of the aerobic area to the anoxic area (denitrification section) and realize denitrification for denitrification under anoxic conditions. Because the water level in the aerobic area is lower than that in the anoxic area, the internal reflux pump installed in this way is very shallow under the liquid level in the aerobic area. When the internal reflux pump operates, it will form a negative pressure in the water inlet area in front of the pump, which is easy to form a vortex (vortex).

进口内回流泵Principle:

The top end face of the upper cover plate extends from the center to both sides in a sag arc, which can slowly and smoothly disperse the liquid above the upper cover plate to both sides of the upper cover plate, avoiding the fluctuation caused by uneven dispersion. Without fluctuation, too much oxygen will not be dissolved in the liquid. Under the action of the upper cover plate, two triangular side baffles and the front baffle, the water flow at the water inlet of the reflux pump
