Aeration water-drawing technology

Abstract

The invention relates to a water pumping technique, which uses aeration as a driving force, has micro pump lift, large flow capacity and low energy consumption, is suitable for any occasions needing to obtain a low water head (generally between 0.2 and 1 meter), and has functions of increasing oxygen and promoting odorous substances to dissipate at the same time. An aerated drawing water device unit consists of a horizontal guide flow cylinder, a vertical aerated cylinder, a sliding sleeve gasket, a floating telescopic cylinder, a ring-shaped floating body, a microporous aerated tray, an aerated tray mounting pipe frame, a gas delivery pipe and a Roots blower, and is arranged on a bank between a water supply body and a water receiving body. When the Roots blower is started, the microporous aerated tray is aerated, a water column in the vertical aerated cylinder is fully filled with bubbles to reduce specific weight, liquid level rises to overflow, complementing water flow is formed in the horizontal guide flow cylinder, water in the water supply body is pumped into the water receiving body continuously, a water head of 0.2 meter can be formed between the two water bodies, and oxygen is increased by 2 to 3 milligrams per liter. According to engineering requirements, a plurality of the aerated drawing water device units can be arranged in series, in parallel or in series-parallel, so as to obtain required flower flow and drawing water height. The engineering technology can be used for driving water current circulation inside a landscape water body, promoting large flow exchange between adjacent water bodies, driving circulation of bypass water circulating systems, lifting water with low pump lift and increasing oxygen inside wetland parks and water quality purifying engineering, and the like; and the water pumping technique has the advantages of simplicity and reliability, pollution and erosion resistance, economy and practicability, and the like.

Description

Technical field: [0001] Micro-lift water lifting engineering technology. The invention relates to a micro-lift, large flow and low energy consumption water lifting technology with aeration as the driving force, which is suitable for any place that needs to obtain a low water head (generally 0.2m to 1m), and has the functions of increasing oxygen and promoting odor Material dissipation function. This engineering technology can be used to drive the water circulation inside the landscape water body, promote the large flow exchange between adjacent water bodies, drive the flow of the bypass water circulation system, low-lift water-lifting-aeration inside the wetland water purification project, etc. Background technique: [0002] Axial-flow submersible pump is a general-purpose low-lift, high-efficiency water-lifting method. The lift is generally above 3m, and the installed power is above 10kw. Taking the 350QZ-50D model with a lift of 3m and an installed power of 15kw as an ex...

AI Technical Summary

Problems solved by technology

If the axial-flow submersible pump on the market is used, the installed capacity and power supply line of more than 10KW are required, and the pump station needs to be built, and there are still problems of corrosion and damage. The construction cost and operation cost are relatively high, which will inevitably cause waste of funds and resources.
