Floatation equipment

Abstract

The invention discloses floatation equipment which relates to the field of mechanical equipment and comprises a barrel, a mud bucket and a gas dissolving device, wherein the barrel is provided with a water inlet and a water outlet, the mud bucket is arranged at the bottom of the barrel and is provided with a mud discharge hole, a drossing device and a slag hole are arranged on the top of the barrel, an inclined plate section is arranged in the barrel and is arranged between the water inlet and the water outlet, a micro-nano bubble generator is arranged between the inclined plate section and the water outlet and is connected with the gas dissolving device, and a micro-nano bubble generating device is arranged in the gas dissolving device. Due to the dual actions of an inclined plate and the gas dissolving device, large-particle flocculating constituents settle to form sludge, and small-particle flocculating constituents float on the water surface; clear water after dual solid-liquid separation is high in recycling standard; since the micro-nano bubble generator is utilized, not only is the gas dissolving efficiency improved, but also the adsorption effect can be realized on grease dirt and other substances, and the floatation effect is greatly improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an air flotation equipment. Background technique [0002] Air flotation equipment is a kind of equipment that removes suspended solids, grease and various colloids in various industrial and municipal sewage. It is an indispensable equipment in sewage treatment. Generally, air flotation equipment is the separation of gas and liquid.

[0002] Air flotation equipment is a kind of equipment that removes suspended solids, grease and various colloids in various industrial and municipal sewage. It is an indispensable equipment in sewage treatment. Generally, air flotation equipment is the separation of gas and liquid. For the solid-liquid separation effect is not obvious, the removal rate is not high, the application number is CN201020185969.8 discloses a kind of air flotation equipment, mainly including dissolved air pump, water inlet pipe, air inlet pipe, two positive pressure regulating valves, air-water separation tank, The air flotation mixing contact area, etc., the dissolved air pump is connected with the water inlet pipe and the air inlet pipe respectively, the air inlet pipe is connected with one side of the gas-water separation tank through a positive pressure regulating valve, and the other side of the gas-water separation tank is connected with the air-water separation tank through a pipeline. One end of another positive pressure regulating valve is connected, and the other end of the positive pressure regulating valve is connected with the air flotation mixing contact area. It is easy to operate and maintain, low in noise, and high in dissolved air flotation efficiency, but its efficiency in removing large particles is not high. Clear water Low recycling standard and high cost
