Vortex dissolved-air floatation system

Abstract

The invention relates to a vortex dissolved-air floatation system which comprises a cabinet and a gas-liquid circulating system, wherein the inside of the cabinet is orderly provided with a floatation contact chamber, a separation chamber and a clear water chamber; the upper end of the floatation contact chamber is communicated with the separation chamber; the separation chamber is communicated with the clear water chamber through a collector pipe; the collector pipe comprises a main pipe and a plurality of attached pipes; the attached pipes are respectively positioned on both sides of the main pipe; one end of each attached pipe is closed, and the other end thereof is communicated with the main pipe; and the wall of each attached pipe is respectively provided with a plurality of water vent holes which are evenly distributed. The invention has the advantages of simple structure and convenient manufacture, evenly collects clear water and reduces the hydraulic stirring of outlet water on the separation chamber, thereby avoiding scum and precipitations from mixing into the clear water chamber, and enabling the clarity of the outlet water to be optimal; a screw rod is manually adjusted to adjust the height of a water level adjustment plate, thereby adjusting the water level in the clear water chamber; and thus, the height of the water level of the water in the separation chamber is indirectly adjusted, thereby ensuring the underwater penetration of a scum scraper and providing convenience for achieving the required scum scraping quantity.

Description

technical field [0001] The invention relates to a dissolved air flotation system, in particular to a vortex dissolved air flotation system. Background technique [0002] Vortex air flotation equipment is mainly composed of three parts: air saturation equipment, equipment for releasing air and mixing with wastewater, and equipment for solid-liquid or liquid-liquid separation. Among them, the dissolved air and release system is the core of the entire dissolved air flotation system. The gas-liquid mixing ratio of the dissolved air, the size, density, and distribution of the released bubbles all have a crucial impact on the treatment effect of the air flotation. When the traditional dissolved air flotation system discharges water, the hydraulic disturbance in the air flotation scum area and the sedimentation area tends to suck the scum floating on the water surface and the sediment at the bottom into the clean water chamber at the same time, resulting in incomplete purification ...
