Product features and performance indicators
It mainly separates oil slick and dispersed oil, and requires special design for emulsified oil and dissolved oil. At the same time, it also has a strong precipitation effect, and the concentration of suspended solids in a short period of time can reach up to 1500mg/L. Secondary degreasing is adopted to reduce the surface load of the inclined pipe area and avoid clogging the inclined pipe. The inclined plate and inclined pipe are made of stainless steel, which has the characteristics of non-stick oil and anti-aging. Using patented technology scraper scraper, good scraping effect. The set auxiliary flushing function effectively prevents the equipment from clogging. Equipped with heating system to ensure the operation requirements of the equipment.High separation efficiency.Smaller investment and operating expenses. Imported oil-containing ≤ 1000mg/L (oil specific gravity≤0.95) SS≤500mg/L; Export oil≤ 100mg/L SS≤100mg/L.
Equipment principle
The sewage enters the primary inclined plate sedimentation area from the upper part, the suspended solids rise to the inclined plate sedimentation area with the water flow, and the shallow pool sedimentation theory is used to quickly shorten the separation time to achieve the effect of rapid solid-liquid separation, and the separated solid suspended solids sink to the mud hopper under the action of gravity, and the large oil droplets float to the liquid surface to remove a larger part of the oil and suspended solids to avoid the oblique pipe blockage of the secondary degreasing area, so as to achieve a better oil removal effect. Sewage enters the secondary inclined pipe area, the suspended solids in the water quickly sink to the inclined pipe, when a certain amount is reached, slide to the mud hopper, together with the sludge in the primary oil removal area is discharged by the sludge pipe, the separation of small oil droplets adopts the aggregation theory, that is, tiny oil droplets in the inclined pipe area due to buoyancy attached to the arc top of the inner surface of the corrugated plate, gradually gathered into larger oil droplets, and then floated to the water surface along the inclined plate, scraped to the oil collection tank through the chain scraper oil scraper, and finally entered the oil drain pipe through the self-flow.
Operation effect and application field
The inclined plate oil removal device installed has met the requirements of use, with a high degree of trouble-free automation and high efficiency in removing suspended solids.
onshore and offshore oilfield wastewater treatment; petroleum refining, petrochemical wastewater treatment; Oily wastewater treatment of ships, port terminals, oil depots and oil tanks; Other industrial oily sewage treatment.
