SU981253A1 - Water aerator - Google Patents

Description

The invention is an ognosigs for hydraulic engineering and water management and can be used for self-cleaning of water bodies due to enrichment of water with oxygen in the air.

A device is known that is intended to enrich water with oxygen by supplying air to a certain depth and containing vertical duct, collection-deaerator, duct pj.

However, the known device is insufficiently effective in operation, i. The aim of the invention is to increase the efficiency of using the aerator due to the intensification of oxygen dissolution in enriched water.

This goal is achieved by the fact that a water aerator containing a vertical channel with an air duct and an air inlet pipe into the water supplied, a collection box for removing excess air located above the channel and communicating with it, is provided with a vertical (& air outlet pipe communicated with

(54) AERATOR WATER COLLECTION-box, as well as a perforated tip attached to the air inlet, in the form of a reverse cone, while the middle part of the channel is made with expansion and 5 heads are placed in it.

The drawing shows a water aerator. The aerator consists of a vertical channel 1, the length of which is determined from

About the intended thickness of the water layer enrichment, the pipeline 2 for supplying air from the compressor, the mixer 3, the collector 4 for releasing air into the atmosphere and the discharge pipe t 5. To increase

Claims (1)

 the water intake area 6 at the beginning of the pipe & x 1 it is possible to arrange a horizontal perforated pipe or a pipe system according to the size of the aerator area. In the mixer there is a cap 7, closed on top of a sheet with holes. The task of the mixer: is to provide the most intensive mixing of water and air. The perforated tip 7 from the water level is placed at a depth determined by the ratio U- - l | 1 (P / PqVl where D d is the sum of hydraulic losses from the water surface in the bundle to the end of pipe 1; f 5о1 water and air mixture. The device works as follows. Compressed air from an compressor or other source is supplied under pressure to a mixer 3. Aerated water rises in a collector 4, where air is separated from water, and oxygen-enriched water under pressure through a pipe 5 is discharged to any predetermined depth. Offered by The plant enriches the waters of water bodies with oxygen in the air, helps them self-clean from harmful contaminants, stimulates the development of biological processes, prevents fish from freezing, etc. The principle of operation embedded in the device allows to enrich water at any depth, and the energy consumption for air pumping and aeradium is weakly dependent on the depth and is determined by the hydraulic losses of the system and the efficiency of the airlift. Claim of the invention A water aerator containing a vertical duct with an air duct and air inlet Water, a collection box for removing air from the bypass jpo, located above the channel and communicating with it, characterized in that, in order to increase the efficiency of use due to the intensification of oxygen dissolution in the enriched water, it is equipped with a vertical exhaust pipe connected to the collection the box, as well as the perforated tamper-shaped perforated pin attached to the air inlet, in the form of a reverse cone, while the middle part of the vertical channel is extended with extension and the tip is placed in it.
