Jinli Gold Lead: green development environmental protection first

The "Environmental Protection Law" reviewed and passed by the Standing Committee of the 12th National People's Congress was formally implemented on January 1, 2015. The new environmental protection law is known as the strictest environmental protection law in history, and it imposes stricter environmental supervision requirements on companies. Green development is opening up new paths for companies to reduce costs, increase efficiency and transform their development.
As one of the top 100 industrial enterprises in Henan Province, Henan Jinli Gold & Lead Co., Ltd. has firmly established the concept of “only misplaced local resources and no real waste”, and regards energy conservation and consumption reduction and environmental governance as a means of transforming business development. With the wonderful move, we continued to optimize the factory's appearance, continuously revitalize industrial wastes such as “waste water”, “exhaust gas” and “waste residue”, vigorously promote the reuse and recycling of by-products or wastes, and achieve energy efficiency and green development. .
The factory area is harmonious and pleasant. The air is clean and the trees are arranged in rows. In the Jinlijin lead plant area, dust and smoke are almost invisible. All the seeing spots are green belts. Towering towers and numerous buildings are surrounded by green forests.
In order to enhance the company’s overall image, last year, the company launched a factory upgrade and renovation project to create a dust-free plant area, re-correct all walls, divide the production area, add more than 300 meters of walls, and all the walls. The whole body is painted; the work intensity of sweeping vehicles and sprinklers is increased, and the frequency of cleaning and watering is increased. In combination with manual cleaning, the health corners are completely removed, so that there is no dead corner in the factory area, and there is no dust or dust in the area.
In addition, Jinli Gold Lead increased the investment in greening and replaced all the unsuitable growing seedlings in the original green belt. A total of 6,000 boxwood seedlings were planted, and the green area was increased by 400 square meters. On the basis of afforestation, green belt road beautification work was carried out. A total of 23 new roads were added and 5 were removed.
Today, the company's overall image is a new look, and the environmental quality of the plant area has been further improved, laying the foundation for creating a “green gold profit”.
Energy-saving and emission-reduction efforts Dajinli Gold & Lead has two bottom-blowing furnaces-side-blowing furnaces-electrolytic 80,000-ton electric lead production lines, supporting two 80,000-ton “two-to-two-suction” sulfuric acid production lines, and the recovery rate of sulfur dioxide reaches 99%. More than %; for the acid produced during the acid production process, the company's construction of the sulphonic acid net system cleans and recycles the acid produced by the acid cleaning station, avoiding the generation of large quantities of heavy metal-containing desulfurized gypsum, and supporting the construction of five electric fields. One dust removal unit and one pulse dust collector are used to remove dust from the bottom-blowing furnace and the reduction furnace flue gas, and two pairs of bottom-blowing furnace systems for the sanitary dust collector, the feed inlet, the lead outlet, and the slag outlet of the reduction furnace are built. Disposal of fume and dust in the batching system, etc., and the removal efficiency of soot can reach over 99%.
In 2014, Jinli Gold Lead invested more than 40 million yuan in the treatment of smelter flue gas, built 4 new “calcium-calcium” double-alkali desulphurization towers, and provided all-weather automatic on-line monitoring facilities for flue gas. The desulfurization system can reduce sulfur dioxide emissions by 148.97 tons and 5.903 tons of soot annually. It can reduce the electricity consumption by 1,457,000 tons per year and generate an annual economic benefit of nearly 15 million yuan. The concentration of flue gas after desulphurization is stable to less than 150mg/m3, far below the national 400mg/m3 and Henan Province's 250mg/m3 emission standards; National standards for nitrogen oxides 240mg/m3, gold and gold lead 140mg/m3 Dust national standard 80mg/m3, Jinli gold lead 20mg/m3.
“Three Wastes” Recycling In the recycling of “three wastes”, Jinli Gold Lead continues its environmental protection work.
The 2010 rain and sewage separation and transformation project carried out by Jinli Gold Lead fully met the requirements of the rain and sewage diversion in the plant area. The collected rainwater was all used for production and was not discharged. In order to increase the removal capacity of heavy metals in wastewater, Jinli Gold Lead invested more than 6.8 million yuan in new wastewater advanced treatment facilities by the end of 2011. After treatment, wastewater can effectively remove heavy metal ions from circulating wastewater and realize the company's production water circulation. Invested more than 1.2 million yuan to add 3 sets of on-line monitoring devices for smoke and SO2 on-line monitoring in real time, and realized real-time data transmission with the Henan Provincial Department of Communications. In November 2014, Jinli Gold Lead successfully passed the fourth round of mandatory clean production review.
In order to comprehensively utilize the solid waste generated in the production process, Jinlijin Lead has built a fuming furnace and built a bag filter at the same time. The dust generated is dust-removed and the efficiency reaches more than 99%. The smoke and dust emissions meet national and provincial environmental protection requirements. Department requirements. In terms of waste residue management, a temporary waste storage yard is set up, and “three defenses” measures are taken. All the suspended waste residues are put into sheds for storage. Wet operations are used during operation to effectively control unorganized dust emissions. (Zhang Li)
