Huangshan Yuanrun invested 49.5 million to upgrade the existing epoxy resin, polyester resin products.

Not long ago, Huangshan Yuanrun New Materials published on its official website its epoxy resin and polyester resin product upgrade technology transformation project environmental impact report.
Project Name: Epoxy Resin and Polyester Resin Product Upgrade Technology Transformation Project
Project Nature: Technical Reform
Construction Unit: Huangshan City Source Run New Materials Technology Co., Ltd.
Construction Location: Huangshan City Luxian Economic Development Zone (Yuxian Recycled Economic Park), with a total area of 15967.47m2 (i.e., Existing production areas, no new land)
project total investment: 49.5 million yuan
main construction content:
(1) demolition of the original polyester workshop, and in this site to build a new methyl propylene glycol storage tank area and the new glycol storage tank area (i.e., 2 s/ storage tank area), a total area of 296m2. The original new glycol bags into cans, and the non-toxic methyl propylene glycol raw materials to replace some of the toxic and harmful binary alcohols (new glycol, glycol, glycol), at the same time can improve the quality of polyester products .
(2) to adjust the layout of the plant: the demolition of the original polyester workshop, in the plant reserved for the new polyester workshop, covers an area of 1077m2, building area of 4077m2;
(3) polyester resin production line crushing process from the existing 2 crushers broken to a set of double steel strip slicer slice, reduce dust emissions.
(4) in order to improve product quality, epoxy resin production line and polyester resin production line each increase 5000L material mixing kettle 2 units.
(5) Existing engineering polyester resin cooling pool 350m3 and fire water share, after technical reform will be fire water and cooling water separate, new fire pump room 1, 1 floor, an area of 19.8m2, with fire pump 2 (electric and diesel each) 1 unit, 1 with 1 preparation), the main pump flow 50L/s, in the west side of the office building to build 2 new fire water storage tanks, storage tank capacity is 270m3 (total effective volume of 540m3), polyester resin cooling pool 350m3.
(6) a new nitrogen machine, nitrogen used in the production process of polyester resin secondary feeding process, reduce material and air contact, to prevent oxidation.
(7) Coal-fired thermal oil boiler changed to biomass thermal oil boiler, combustion exhaust gas treatment facilities from "multi-tube cyclone and water mill" to "multi-tube cyclone and cloth bag"; The vacuum exhaust gas and discharge exhaust gas (non-methane total hydrocarbons) were changed from the original 1 set of "water washing and activated carbon adsorption" waste gas treatment process to 1 set of "spray washing tower, multi-media catalytic oxidation and spray washing tower".
(8) the cooling circulating water system replacement water directly discharged to the park municipal rainwater pipe network, instead into the plant sewage regulation collection pool collection, through the plant's total discharge discharge to the park sewage pipe network, into the park sewage treatment station treatment. Existing engineering polyester resin production wastewater (esterized wastewater, organic waste gas washing tower wastewater) after fenton oxidation treatment, with the rest of epoxy resin production wastewater, workshop equipment floor flushing water, etc., together through the sewage collection pool 1 ( 230m3), in progress and adjust the pretreatability, with After the pre-treatment of office sewage in the plant, the water quality of the total discharge of the plant conforms to the "synthetic resin industrial pollutant discharge standard" (GB31572-2015) table 1 "indirect discharge" standard and the park to take over the standard limits, discharged into the park sewage treatment plant treatment. After the technical reform of the new sewage collection pool 2 s (800m3) wastewater treatment process unchanged, polyester resin production wastewater (esterified wastewater, organic waste gas washing tower wastewater) after fenton oxidation treatment, with the rest of epoxy resin production wastewater, workshop equipment floor flushing water, cooling circulating water system replacement drainage into the sewage collection pool 1 (230m3) and the new sewage collection pool 2 (800m3), water quality in accordance with the "synthetic resin industrial pollutant discharge standards" (GB31572-2015) table 1 "indirect discharge" standards and park takeover standard limits, discharged into the park sewage treatment plant treatment.
