23" Cooking Waste Oil Solid Bowl Decanter Centrifuge 2/3 Phase Separation

23" Cooking Waste Oil 2 Phase Separation Solid Bowl Decanter Centrifuge

Kitchen waste, commonly known as lame, is also known as swill, drowning, food processing waste (food waste) and edible residue (squat). Its composition is complex, mainly oil, water, peel, vegetables, rice noodles, fish, meat, bones and a mixture of waste utensils, plastics, paper towels and other substances. From the chemical composition, there are starch, cellulose, protein, lipids and inorganic salts.

★ Technical features of Centrifuges:

1. With a wide range of applications and strong compatibility, it can handle all kinds of organic wastes, including kitchen wastes, rubbishes after dining, vegetable market wastes, and agriculture and forestry wastes.

2. With patented multi-stage crushing technology, it can achieve 100% crushing and utilization of organic matters to avoiding waste, enhance utilization of organic matters, and improve economic benefits.

3. With patented flexible limit crushing technology, it can realize the maximum separation of inorganic substances to avoid the inorganic substances from mixing with the organic slurry and prevent the inorganic substances from affecting the treatment effect of subsequent process, and to protect the normal operation of subsequent processing equipment.

4. The treatment process is safe and environmentally friendly, and free of pollution discharge such as wastewater and waste gas. The wastewater can be recycled after treatment, which is economical and energy-saving.

I. Kitchen wastes pretreatment system

Our pretreatment system consists of a stainless-steel storage and feeding system, a double-shaft shredder, a screw conveyor, a pipe-type magnetic separator, a kitchen pulper, a belt conveyor, a slurry tank, a transfer pump, pipes, detection instruments, etc.;

The collected swill is poured into the stainless-steel storage and feeding system (with shaftless screw conveyor), and the solid is transported from the shaftless screw conveyor to the slag discharging port on top, and discharged to the double-shaft shredder for crushing. The liquid in the swill (containing fine slurry particles) enters the water tank through the screen of the stainless-steel storage and feeding system, which is furnished with a backwashing device that can effectively prevent the screen from being clogged. The stainless-steel bin has a grille net to prevent some large pieces (plastic barrels, glass bottles, etc.) from being mixed into the shaftless screw conveyor.

The kitchen pulper is filled with 80°C or higher water in the pulping process to clean its screen. The light materials like plastics crushed by the kitchen pulper are discharged from the slag discharging port of the kitchen pulper and sent to the inorganic collection box through a belt conveyor; the slurry generated is discharged from the slurry port of the kitchen pulper to enter a screw extruder with a filter to form a long strip-shaped large-grain type solid to be removed. After that, the slurry is discharged from the screw extruder to the slurry tank.

The slurry produced by the liquid collection bin of the stainless-steel feeding system, the liquid collection bin of the shaftless screw conveyor, and the screw extruder enters the slurry tank. After removal of large gravel, the slurry is sent to the heating tank with steam heating and stirring functions to be heated to above 80°C. After 30 minutes of heat preservation, the slurry in the heating tank is sent to the three-phase centrifuge by a screw pump for three-phase separation of oil + water + slag.

Effect of kitchen waste slurry after treatment by

The kitchen wastes after sorting, crushing, pulping, heating, and three-phase separation in the centrifuge are as follows:

Effect after separation by the three-phase centrifuge

Characteristics of high-efficiency LWS series three-phase centrifuge

Ingenious, unique and diversified three-phase separation structure. The liquid separated by the high efficiency three-phase centrifuge is discharged in two different modes, namely gravity discharging and discharging through the built-in centripetal pump with pressure, wherein the latter includes liquid layer fixed mode and the online adjustable mode of heavy phase liquid layer, which is selected according to the process conditions.

★ Light phase liquid layer adjustment technology (company patent technology, patent number: 2018213324892)

The light phase liquid adjustment sheet is concealed, and the high-efficiency LWS series three-phase centrifuge adopts patented technology, so that adjustment can be completed without disassembling the machine.

★ High performance wear-and corrosion-resistant cemented carbide

Because the kitchen waste slurry in the high temperature state contains corrosive and abrasive substances like salt, glass fragments, and sandstone, the [ZK Separation] centrifuge has a certain degree of pertinence in the selection of wear-resistant materials.

★ High performance stainless steel

After the high temperature hydrolysis of the kitchen waste slurry, due to finer solid particles and 0.1-0.08 g/cm³ liquid density difference (compared with oil and water), the centrifuge needs a separation factor of more than 3000G to achieve the best separation effect. Model SAF2205 with high strength and corrosion resistance is adopted to ensure the stability and service life of the centrifuge.

★ Three-phase centrifuge model and technical parameters
