Pulse water distributor

Abstract

The invention relates to a pulse water distributor which comprises a shell, a water inlet pipe arranged on the shell, a central water outlet pipe arranged in the shell, and a vacuumizing pipe, wherein a water-sealed tank is additionally arranged under the shell; the central water outlet pipe is composed of an inner pipe and an outer pipe; the outer pipe is a seal chamber; the upper end of the inner pipe extends into the chamber of the outer pipe, the upper end port is positioned near the top end of the chamber of the outer pipe, and the lower end of the inner pipe vertically penetrates downwards out of the bottom of the shell and extends into the water-sealed tank; one end of the vacuumizing pipe is connected with the top end of the outer pipe, and the other end extends out of the bottom of the shell and is connected with the water-sealed tank; a multilayer grid plate is arranged in the water-sealed tank; the vacuumizing pipe is additionally provided with a siphon auxiliary pipe which forms a Y-shaped three-way connection with the vacuumizing pipe; and the tail end of the siphon auxiliary pipe faces down against the bottom of the shell. The pulse water distributor can greatly and effectively lower the air inclusion amount of pulse effluent water by more than 70%, reduce the oxygen content of influent water by 0.2 mg / L, and reduce the sludge loss by more than 50%.

Description

technical field [0001] The invention mainly relates to a device for continuous water inflow and intermittent instant water outflow, in particular to a water inflow distribution and hydraulic agitation device for hydrolytic acidification, anaerobic, denitrification and denitrification processes in industrial wastewater treatment. Background technique [0002] In the hydrolytic acidification, anaerobic, and denitrification processes in industrial wastewater treatment, several types of pressure water intake + perforated pipe for water distribution, gravity water intake + mechanical stirring, and pulse water intake + perforated pipe for water distribution are commonly used. Among them, pressure water intake and mechanical stirring have the disadvantages of large power consumption and high fault frequency. Pulse water distribution has the advantages of low energy consumption, less faults, and simple maintenance, and is more and more used. However, the current pulse distribution in...

Problems solved by technology

The technical improvement plan proposes a pulse-type water distributor with a simple structure. The defect still lies in that a large amount of air will be entrained when the water exits the pipe, causing the above-mentioned excessive oxygenation, and the air floats up to cause a part of the sludge to be lost.
