Crystallizer coverpiped КПНК-180-40

is intended for use in the refrigerating blocks of crystallization as a component unit of the technological plant of production of oil, paraffin, ceresin and the refinement of the synthetic fatty acids. КПНК-180-40 consists of 4 sections, with the inner fixed in racks tubes equipped with the revolving (by means of four reduction gear drive) scraper units inside the tube. Sections are connected by double-flowing vertical scheme equipped with the accumulator on the each flow. Refining product - refined oil (distillate), gatch-solvent (methyl ethyl ketone) mixture is loaded in the inner tubes through connecting pipe. Refrigerating medium (propane, ethane, ethylene) is loaded in the casings through connecting pipe. Pipe-bend fume of the refrigerating medium realizes through the connection pipe on the accumulator. During the cooling of the refining product paraffin carbohydrates are being crystallized. Crystals settle on the inner surface of the inner tubes and are being removed by the revolving scraper units. Received suspension circulates for filtration in the filter section of the plant. For cutting expenses on the refrigerating medium, part of the filtrate is forwarded as s refrigerating medium in the external pipes of the regenerative Crystallizers type КПНК-100-70. .
