Constant pressure jet water purifier

Abstract

The invention relates to a constant-pressure jet-type water purifier. The constant-pressure jet-type water purifier comprises a shell, a mixing chamber, a reaction chamber and filtering chambers. The constant-pressure jet-type water purifier is characterized in that a nozzle pipe is arranged at the bottom of the shell; the lower end of the nozzle pipe is connected with a raw water pipeline through a water inlet pipe and a water inlet switching valve; the upper end of the nozzle pipe extends into the mixing chamber, and a nozzle is arranged at the upper end of the nozzle pipe; a settling chamber is constructed by a shell inner cavity space outside the mixing chamber and the reaction chamber; the bottom of the settling chamber is an active sludge active sediment area; a blow-off pipe which is communicated with the active sludge active sediment area is arranged at the bottom of the shell; the upper part of the inner cavity of the shell is provided with a sloping plate assembly; the sloping plate assembly comprises at least two layers of perforated sloping plates; the inclination directions of the adjacent perforated sloping plates in upper and lower layers in the sloping plate assembly are opposite; the pore diameter of the upper-layer sloping plate is smaller than the pore diameter of the lower-layer sloping plate; spaces below filter plates are clear water areas; all the clear water areas are communicated with one another; a water outlet pipe which is communicated with the clear water areas is arranged at the bottom of the shell. The constant-pressure jet-type water purifier has the advantages of low energy consumption, complete blowdown, realization of continuous water supply and small floor area.

Description

Technical field [0001] The invention relates to a water treatment equipment, in particular to a constant pressure jet water purifier. Background technique [0002] Natural water often contains impurities such as sediment, clay, humus, starch, algae and other organisms. They are in the state of suspension, sol and polymer in the water. They all have a certain degree of abundance and stability and their different properties, which constitute water turbidity. , Color and other harmful effects need to be purified. However, it is difficult to effectively remove these impurities only by simple precipitation, filtration and other direct separation methods, so it is often necessary to pre-dosing appropriate chemicals for coagulation and flocculation. [0003] The water purifier is suitable for industrial and production water. Its working principle is to add a flocculant to the water to form agglomerates-alum bloom in the reaction chamber. The larger agglomerates sink into the sedimentatio...

Problems solved by technology

However, in the actual use of the earlier water purifiers, there were problems such as a large load of the filter sand layer in the filter chamber, unstable water output, and long backwashing time of the filter sand layer, which affected the water production efficiency of the equipment and high labor intensity.
