Efficient dissolved air flotation machine

Abstract

The invention provides an efficient dissolved air flotation machine. The air flotation machine mainly comprises two air dissolving systems, an oil receiving pool, a mud scraping system and an output pump. A mud scraping machine of the air flotation machine adopts a stainless steel inner liner, a framework and a nylon chain, the strength of the chain is enhanced, and electric sparks are not easily generated. The air flotation machine is provided with an oil storage pool, and the technological process is reduced. The air flotation machine initiates double air dissolving systems, so that energy is saved, the processing effect can be improved, and the spare air dissolving system exists during breakdown maintenance. The air dissolving system of the air flotation machine are additionally provided with an air intake flow meter and an adjusting valve, so that the function of automatic adjustment of a gas liquid ratio can be realized, and the air dissolving efficiency is improved. An air dissolving tank of the air flotation machine is additionally provided with an automatic air exhausting device, so that the air dissolving effect is always kept in the best position. The sump oil and sludge systems of the air flotation machine share one pump for outputting, the cost is reduced, and the space is saved.

Description

Technical field: [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency dissolved air flotation machine. Background technique: [0002] For the removal of suspended solids, grease and other sundries in various industrial and municipal sewage, if the traditional sedimentation method is used, the effect will be poor, especially in low temperature conditions in winter, due to the deterioration of coagulation and hydraulic conditions, the treatment effect will be even worse It is difficult to guarantee that the use of the air flotation machine can just change this phenomenon. The air flotation machine introduces air bubbles into the water to make them adhere to the flocs, thereby greatly reducing the overall density of the flocs, and by virtue of the rising speed of the air bubbles, Force it to float up to achieve rapid solid-liquid separation. In this sense, the appearance of the air flotation machine is a revolution to the g...

[0002] For the removal of suspended solids, grease and other sundries in various industrial and municipal sewage, if the traditional sedimentation method is used, the effect will be poor, especially in low temperature conditions in winter, due to the deterioration of coagulation and hydraulic conditions, the treatment effect will be even worse It is difficult to guarantee that the use of the air flotation machine can just change this phenomenon. The air flotation machine introduces air bubbles into the water to make them adhere to the flocs, thereby greatly reducing the overall density of the flocs, and by virtue of the rising speed of the air bubbles, Force it to float up to achieve rapid solid-liquid separation. In this sense, the appearance of the air flotation machine is a revolution to the gravity sedimentation method. It has opened up a new field of solid-liquid separation technology. The gas-liquid ratio of the flotation machine cannot be adjusted automatically. When the working conditions change, the gas-liquid ratio needs to be manually adjusted. At the same time, there is easy air in the dissolved air tank, which cannot maintain the best gas-liquid ratio and affects the air flotation effect.
