Daye Peak Desulfurization Project Breaking Earth

News # July 22 , accompanied by a series of firecrackers and a wave of the excavator's vibrating arm, Daye Peak Cement Company's desulfurization project officially broke ground. This is another environmental protection project implemented by the company after the denitration project.

In the "Emission Standard for Air Pollutants from Cement Industry" implemented on 3 1 , 2014 , the emission of sulfur dioxide (SO2 ) per standard cubic meter in cement production is required to be no higher than 200 mg, while the standard in economically developed regions such as Guangdong, Shandong, Beijing, Tianjin, Hebei and Hangzhou is no higher than 100 mg, some provinces that implement total emission control will control the emission requirements below 20 mg. The continuous stringent emission standards have brought great environmental pressure to the cement industry. Sulfide in cement production mainly comes from sulfur-containing raw materials such as coal, limestone and clay. At present, the mainstream desulfurization methods include wet desulfurization, dry desulfurization technology, ammonia desulfurization technology and compound desulfurization technology. The desulfurization project implemented by Daye Peak this time adopts limestone wet flue gas desulfurization process, which is currently the most widely used and mature standard desulfurization process technology in the world. The process uses cheap and easy-to-get limestone as a desulfurization absorbent, limestone is crushed and ground into powder and water mixed into an absorption slurry, in the absorption tower contact with the flue gas mixed, the sulfur dioxide in the flue gas and the calcium carbonate in the absorption slurry, the air drum into the chemical reaction is removed, the final reaction product is gypsum. The flue gas after desulfurization is removed by the mist eliminator and discharged into the chimney after warming up. The desulfurization gypsum slurry is dehydrated by the dewatering unit and recycled for cement grinding. The completion and operation of this project can not only effectively reduce the content of sulfur dioxide in flue gas, but also realize the partial self-sufficiency of desulfurization gypsum in cement grinding.

Peak natural products among the top 20 scientific and technological innovation in TEDA

A few days ago, Tianjin Jianfeng Natural products Research and Development Co., Ltd. stood out among nearly 35000 enterprises in Tianjin Development Zone and won the honor of "Top 20 Scientific and technological Innovation Enterprises of 2015. The selection criteria for the top 20 scientific and technological innovation enterprises in Tianjin Economic and Technological Development Zone mainly include: they have won science and technology awards or patent awards in 2015, as well as other awards above the provincial level; they have obtained the qualification certification or approval of research and development institutions above the provincial level; in 2015, the number of invention and utility model patent applications and authorizations was large, totaling more than 15; in 2015, they were supported by national or Tianjin key science and technology plans; scientific research achievements have made significant progress and technology. According to the above standards, Jianfeng Natural Products Company has not only won the second prize of Tianjin Science and Technology Innovation Project Award for the achievements of "Tianjin Plant Waste Reutilization Technology Engineering Center Construction", but also completed the process research of grape seed extract and ginsenoside to pesticide residues, and formulated the international business standard of grape seed extract (grape seed oligomeric proanthocyanidins). In order to better carry out the pilot experiment, large-scale technical transformation was carried out on the second workshop, and the process optimization of extracting anthocyanins from blueberries has been carried out. At the same time, the main business income, operating profit, tax revenue and other economic indicators of peak natural products company in 2015 have increased significantly year-on-year. Relying on the advantages of excellent quality, good efficiency, great contribution, safety and environmental protection, and good social responsibility, Jianfeng Natural Products Company successfully passed the review and became one of the "Top 20 Scientific and Technological Innovation Enterprises in 2015" in Tianjin Development Zone.

Peak pharmaceutical "enterprise information construction project" through the acceptance

The "Enterprise Informatization Construction Project" of Jianfeng Pharmaceutical Company was included in the list of key projects of "Integration of Industrialization and Industrialization" (high-level and in-depth combination of informatization and industrialization) in Jinhua City in 2015, and successfully passed the on-site acceptance of the expert group on the morning of May 18. The main contents of the "enterprise information construction project" of the pharmaceutical company include: the tank farm control system, which solves the problem of closed metering and transportation of organic solvents between the tank farm and the production area, can automatically realize the terminal metering setting, and effectively ensure the safety and environmental protection requirements of the tank farm operation; The air conditioning automatic control system realizes the control of the temperature, humidity and room pressure difference in the air conditioning area through the PLC digital-to-analog conversion of the upper computer and lower computer and the terminal actuator regulator, ensure the cleanliness requirements of the production area environment; The online particle monitoring software system automatically adjusts to the standard flow through the upper computer, vacuum system, laser sensor and isodynamic sampling probe, etc. through the flow detector device and key orifice plate inside each sensor, monitors the temperature, humidity, particles, planktonian bacteria, room pressure difference, etc., implements dynamic management, and realizes visual monitoring of the production process environment. MRP production management system, it makes it easier for the warehouse, workshop, and management personnel to obtain information about the flow of materials in the production process, the implementation of production plans, and product inventory. During the on-site acceptance on the 18th, the acceptance team composed of the Information Department of the Municipal Economic and Information Commission, the Economic and Development Bureau of the Development Zone, the Municipal Information Promotion Association and professors of Zhejiang Normal University checked the contracts of each system software, purchase and transfer records, training records, and problem records in project implementation,
