Product Description


Multiphase flow dissolved air flotation(new type, QTRF series)

Note: This type of air flotation and pressure dissolved air flotation the same size, but the dissolved air way is different, more energy-saving, easier to operate. QTRF air floater is a new type of air floatation equipment developed by our company, which combines the situation of our country and the characteristics of our industry, the air dissolved in the water forms bubbles of 20-30μm in the air-flotation tank, which has high surface area and adsorption capacity. QTRF series multi-phase flow dissolved air floater can effectively remove grease, colloid, solid suspension, Bod and COD from sewage. It is installed before biochemical secondary Sewage Treatment, the size of the plant could be significantly reduced, thereby reducing a significant overall investment cost. The machine itself covers an area of saving, it no longer needs pressure vessels, air compressors and circulating pumps and other equipment, reduce a lot of sewage treatment equipment investment costs.

A, the machine can sewage treatment capacity of 320 M3/h.

B. the minimum wastewater treatment capacity of the machine is 5m3/h. C, mud scraper per minute linear speed 5.16 m ~ 25.8 m/min (stepless speed) .

D, the rotating speed of the screw propeller is 24r/min.

 The whole air-flotation system consists of four parts:

A) reaction section

B) air-flotation section

C) chain mud scraper

D) screw-driven solid discharge machine II.

QTRF air-flotation machine is suitable for industries such as paper making, municipal sewage, chemical industry, beverage industry, printing and dyeing industry, oil refining industry, electroplating industry, food industry, textile industry, slaughtering industry, leather industry, dairy industry, etc. . It involves the application of suspension separation, oil-water separation and purification, flocculation reaction floc separation, activated sludge separation, etc. .

The basic principle of QTRF series dissolved air floater untreated sewage first enters the reaction chamber, fully contacts with the liquid medicine, flocculates to the air floatation section, where it is fully mixed with the micro-bubbles produced by the bubble generator, the working principle of the bubble generator is to use the gas-liquid mixed pump to absorb water and air, and to add pressure to mix inside the pump to produce 20-30μm micro-bubbles. Because of the imbalance between the air-water mixture and the liquid, a vertical buoyancy force is generated, bringing the solid suspension to the surface. As they rise, micro-bubbles attach to the suspension, and when they reach the surface, the solid suspension is supported and maintained on the water surface by these bubbles, and is removed by radial airflow thrust. The solid suspended matter floating on the water surface is continuously removed by the mud scraper, which moves along the entire liquid surface and pushes the suspended matter from the inlet end of the air flotation tank to the outlet end. The scraper of the mud scraper is fixed at both ends of the chain, and the mud scraper is driven by the sprocket transmission driven by the stepless speed governor. The scraper moves along the entire width of the trough, scraping contaminants onto the inclined metal plate and pushing them into the sludge discharge line. There is a horizontal screw propeller in the sludge discharge pipe, which sends the collected sludge to the sludge collection vessel. The screw propeller is driven by a special motor. The purified sewage will enter the overflow trough through the outlet under the metal plate before discharging. The overflow tank is used to control the air flotation tank to ensure that the liquid in the tank will not flow into the sludge discharge pipe.

QTRF series dissolved air flotation advantages (performance characteristics) : 1, while suction, while suction, pump pressure mixing, high gas-liquid dissolution efficiency, fine bubbles 20 -30 microns. 2. Air floatation device can replace pressure pump, air compressor, large-scale dissolved gas tank and release head, etc. . It can overcome the problems of unstable operation and big bubble boiling of traditional device. 3. With the condition of automation, low noise, good energy-saving effect. 4. Advanced Technology, high treatment efficiency, low operation cost, good effluent quality.
