2021-04-12
2021 , daye peak cement company reformed the permanent magnet direct drive frequency conversion speed regulating motor of kiln tail exhaust fan and 2 cooling tower fan. after a period of operation, the effect was obvious.
kiln tail exhaust fan was renovated, the original low-efficiency fan was removed and replaced by Halifax high-efficiency energy-saving fan; The air duct was optimized, and the inlet air duct of the tail exhaust fan was increased to reduce resistance. Remove the bypass air duct from the original desulfurization tower to the kiln tail chimney. After the transformation is completed, under the same speed, the motor current will drop to 30A , the power will drop to 400KW , and the annual power saving is expected to be 288 kwh . At the same time, Daye Peak also replaced the filter bag of the cloth bag dust collector at the end of the kiln. After the replacement, the differential pressure decreased from the original 1200-1300Pa to 800-900Pa .
Daye Peak Waste Heat Power Generation Circulating Pool has two cooling fans. The driving mode is "variable frequency motor +reducer " . This driving mode will cause problems such as oil leakage, high temperature, many faults of high-speed shaft and many transmission links of reducer. From the driving component motor to the load shaft, there is energy loss in each link, as a result, the overall efficiency is low, the system efficiency is around 75% , and the energy loss is large. After completing the transformation of permanent magnet direct drive variable frequency speed regulation motor, the motor runs smoothly, the vibration is small, and the power saving effect is obvious. The later maintenance eliminates the maintenance of the reducer. At the same speed, the current drops by 40% and the power drops by 27% after changing to the variable frequency speed regulation drive mode of permanent magnet direct drive motor.

Publicity of Environmental Protection Acceptance for Completion of Kiln End Flue Gas Desulfurization Project of daye peak cement co., ltd. According to the requirements of the Interim Measures for Environmental Protection Acceptance for Completion of Construction Projects (No.4 [2017] of the State Environmental Regulations) issued by the Ministry of Environmental Protection, the environmental protection acceptance information of "Kiln End Flue Gas Desulfurization Project" of daye peak cement co., ltd. is now publicized. Basic Information of 1. Project Project Name: Kiln End Flue Gas Desulfurization Project Construction Unit: daye Jianfeng Cement Co., Ltd. Project Construction Location: Yongguang Village, Baoan Town, daye city, nature of the project in the existing plant area of daye Jianfeng Cement Co., Ltd.: The construction content of the technological transformation project is: This technological transformation project is mainly to build a wet desulfurization system for kiln end gas of the company's existing 4000t cement clinker production line, adopting limestone-gypsum wet flue gas desulfurization process. The project covers a total area of 500 m2, with a new construction area of about 450 m2. It mainly builds desulfurization complex building, flue gas system, SO2 absorption system, limestone powder conveying and limestone slurry preparation system, process water system, gypsum dehydration system and supporting pipelines. Power supply, water supply, compressed air and other public works rely on the existing plant. Total investment and environmental protection investment: the total investment of the project is 10.37 million yuan, all of which are environmental protection investment. The project was entrusted to Huangshi Yangtze River Environmental Engineering Design and Research Institute to carry out environmental impact assessment in September 2017. On November 16, 2017, Daye Municipal Environmental Protection Bureau issued a reply with YEHAN [2017] No. 354. Implementation of 2. environmental protection measures The scope of this acceptance is the flue gas desulfurization system and supporting facilities at the end of the kiln. (1) Exhaust gas pollution

Spike New Drug Approved for Registration
On April 16, Jianfeng Pharmaceutical Company received the approval and issuance of Olopatadine Hydrochloride Eye Drops "Drug Registration Approval" (approval number: 2019S00296) approved by the State Drug Administration. Olopatadine hydrochloride eye drops is mainly used to treat the signs and symptoms of allergic conjunctivitis. It is a mast cell stabilizer and a relatively selective histamine H1-receptor antagonist. It can inhibit type I immediate allergic reactions in vivo and in vitro experiments. At present, the product has been included in the "National Basic Medical Insurance, Work Injury Insurance and Maternity Insurance Drug Catalog (2017 Edition)" and classified as Class B. According to the relevant data of IMS database, in 2018, the global sales of olopatadine hydrochloride eye drops were about 0.37 billion US dollars, and the sales in China were about 10.232 million US dollars. Spike Pharmaceuticals already has the corresponding production line, this time to obtain the registration approval, marking Spike Pharmaceuticals has the qualification to carry out the production and sales of olopatadine hydrochloride eye drops, will further enrich the product line of Spike Pharmaceuticals, help to enhance the competitiveness of the company's pharmaceutical business.
