Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical equipment, in particular to a new energy material air flotation device. BACKGROUND

[0002] The Chinese patent application with the publication number CN102161519A discloses a sealed vortex centripetal air flotation oil removal method. The oil-containing sewage is dissolved with air on the water inlet pipe of the container tank, and the oil-containing sewage after air dissolution enters the sealed vertical cylindrical container tank tangentially to directly generate vortex rotation or enters the vortex member in the sealed container tank to generate vortex rotation by the vortex member. The centrifugal force generated by the vortex rotation carries the oil and gas to the inner circle, and after the oil and gas are gathered in the inner circle, the oil is floated to the top of the tank by the buoyancy of the gas, and the oil is taken out by the gas from the oil collection port at the top to be recycled. The oil-removed sewage is sent to the next stage for treatment. This sealed vortex centripetal air flotation oil removal method can be used alone or together with other oil-containing sewage treatment devices.

[0003] The above technical solution has the following disadvantages: 1. The size of the bubbles is uneven, and the oil removal efficiency is unstable; 2. A relatively high rotation speed and pressure need to be provided, and the energy consumption is relatively high, which increases the operation cost; 3. Compared with traditional oil removal equipment such as gravity settling tank, the initial purchase and installation cost of the vortex centripetal air flotation equipment is high; 4. The equipment structure is complex, the internal flow field control is strict, the manufacturing precision is high, and professional technical personnel are needed for maintenance, which increases the cost and workload; 5. Due to the complex design of the equipment, the parameters cannot meet the expected requirements when purifying high-difficult materials during actual operation; 6. The air flotation efficiency is not high, and high-purity materials cannot be obtained.

[0004] The Chinese invention patent application with the publication number CN113582384A discloses a cyclone air flotation oil removal device, which is composed of a cyclone mixing reaction device and an air flotation device. The cyclone mixing reaction device is composed of a water inlet booster pump, a first hose, a pipeline mixer, a second hose, a first cyclone, a third hose, a second cyclone, a fourth hose, and a third cyclone. The air flotation device is composed of a fifth hose, a dissolved gas release tank, a separation tank, a water outlet tank, a conical slag collecting tank, a slag falling pipe, a slag storage hopper, a sludge storage hopper, a slag scraper, and a spiral sludge scraper. The cyclone air flotation oil removal device emulsifies and demulsifies the oil in the high-pressure inlet water through the cyclone, and then the demulsified oil and the suspended matter are jointly destabilized, coagulated, and flocculated, while the air is dissolved to form air-embedded light floc. The floc can quickly rise to form ultra-light floating slag in the air flotation tank after pressure release. The device has good flocculation effect, high air dissolving efficiency, low water content of floating slag, and high removal rate of emulsified oil, Ss, particles, and colloidal COD. The device is compact, occupies less space, and has high removal rate of emulsified oil, Ss, particles, and colloidal COD.

[0005] The above technical solution has the following disadvantages: 1. The conventional air flotation device produces large-diameter bubbles (such as the bubble diameter of the impeller air flotation is not less than 0.1 mm), which is difficult to effectively adhere to the small particles with water-like specific gravity in new energy high-difficulty materials, affecting the separation efficiency; 2. The surface active substances in high-difficulty material wastewater may change the surface properties of particles, reducing the adhesion stability of bubbles and particles; 3. Conventional air flotation is difficult to quickly and effectively remove high-concentration micro-suspended matter or dissolved matter, and the treatment efficiency decreases; 4. It is sensitive to changes in wastewater quality, such as pH value, temperature, pollutant type and concentration, affecting the air flotation effect, and frequent adjustment of process parameters is required. The equipment occupies a large area, and the operation and maintenance are complex; 5. For high-difficulty material wastewater with special properties, additional pretreatment or post-treatment equipment may be required, increasing system complexity and investment cost; 6. When treating high-difficulty wastewater, higher dissolved gas pressure and energy consumption may be required, increasing operating costs; Special components in wastewater may cause equipment blockage or damage, increasing maintenance frequency and cost.
