8. equipment investment

Guided by market application technology, participate in bidding for major national key projects, obtain bidding notification number, implement third-party operation management technical service mode of environmental protection special facilities, invest patented technology "Method and Device for Separating and Purifying Active Silica Powder from Electric Furnace Smoke" to help smelting enterprises transform traditional smelting dust collectors, and convert waste smoke discharged without organization into new powder material-active silica powder. An annual waste of 2500 tons of dust generated by one submerged thermal electric furnace (national access standard electric furnace 12500kva) is recycled, and the investment in technical transformation costs are 3 million yuan. The technical transformation of 10 12500kva submerged thermal electric furnace dust collectors is 30 million yuan. The new powder material-active silicon powder is recycled. There is no pricing agency in the market. The sales price is approved based on application technical services and technology development.

9. Annual operation and maintenance fee

Activated silicon powder is in the category of smelting solid waste. Equipment operation, equipment depreciation, and recycling labor wages and packaging costs are developed for comprehensive utilization technology of waste resources, followed by the cost of warehousing and secondary transfer, and the annual operating cost per ton is 1200 yuan/ton, and the annual operating cost of a 12500kva submerged thermal electric furnace is 3 million yuan.

10. investment recovery period

Green industry new technology and new materials-activated silicon powder market development technology The payback period for investment depends on the market application of the project. With sufficient self-owned funds or bank-supported working capital, extensive market applications can be developed. In the development and operation of technical services, project investment The payback period is 24 months, which can not only recover investment and have better profits.

11. added benefit

The emergence of green industry new technologies and new materials-activated silicon powder market development technology not only promotes the widespread application of activated silicon powder in the market, but also drives other metallurgical and smelting waste resources The development of comprehensive utilization technology for (slag powder, steel slag powder, fly ash) and the revolution of high-strength, high-performance and durable structural raw materials have been achieved. Mineral additives composed of slag powder and fly ash have replaced portland cement in high-strength and high-performance durable structures. The application in durable structures not only creates conditions for new materials to enter cutting-edge technologies in the construction industry, reduces the cost of concrete, and improves the quality of concrete structures.

12. comprehensive benefits

activated silicon powder (Silica Fume) is a slag-free smelting process technology from silicon alloy smelting. It combines the waste smoke and dust emitted unorganized during smelting, which is one of the sources of haze and meteorology. Traditional environmentally friendly dust removal technology only uses waste smoke and dust to be recycled and landfill disposal, without considering the market application of smoke and dust, which also creates secondary pollution hazards caused by the landfill waste smoke under the action of the natural environment. It uses independent intellectual property rights-patented technology and the National Torch Plan project "Smelting Flue Gas Purification, Implementation of a new material for soot separation and purification-activated silica powder "and the national key new product project" Silica Fume ": using the patented three-level separation and purification technology, the silicon-based soot ash disposed of is transformed into a new siliceous ultra-fine powder material. Its powder structure is: gaseous three-dimensional, cotton-like amorphous bead-shaped structure, and activated silica powder (silicon dust) is included in the design guidelines of the Hong Kong-Zhuhai-Macao Bridge Project.

13. Level of impact of obstacles on technology transfer

The obstacle to the technology promotion of this project lies in the policy orientation. Although there are national policy guidelines, it is difficult to implement it. Since the national strategic emerging industries put the development of new technologies in green industries first, the implementation is implemented on other projects, and the science and technology funding is also basically not biased towards new technologies in ecological green industries. The technology transfer of environmental protection industries generated by the project also requires funds and capital promotion. However, technical services for environmental protection industries are not supported by the banking and financial circles. Create obstacles to technology transfer and promotion.

14. technology maturity

The process routes for the generation and implementation of this technology are divided into 1. The third-party operation and management technical service model for special facilities in the environmental protection industry, replacing waste resources with technical services, recycling and utilizing; 2. The market application of the new powder material-activated silica powder The development of technological process routes, through extensive market development, the technologically mature and complete mineral admixture technology using activated silica powder + slag powder + fly ash involves: Technical process of high-strength, high-performance and durable concrete structures; technical process route of ultra-high performance concrete structures (UHPC structures); technical process route of reactive powder concrete structures (RPC structures), and raw material production technology of 3D printing technology in the construction industry.

15. technical applicability

The conditions for use of new materials are in the concrete industry of the construction industry. Concrete structural products are made of a mixture of cement + sand + additives + water. Since the durability standard of concrete structures has gone from the traditional 30 years to 50 years, it is now 100 years---120 years, domestic and foreign building standards have been improved, and the production conditions of traditional portland cement are limited by the production requirements of land and mine resources and environment. New powder materials to promote the development of comprehensive utilization technology of metallurgical and smelting waste resources, and new materials for activated silicon powder + slag powder + fly ash mineral admixture admixture, also require the implementation of relevant use technologies in accordance with market technology.

16. technical stability

Technical specialization determines the stable operation of technology in the project. In response to the particularity of the smelting industry, we will implement the industrialization development of environmental protection pollution control, realize the third-party operation and management technical service model of special environmental protection facilities, and ensure that each "smelting electric furnace flue gas purification," The recovered active silica powder New Material for Separation and Purification of Powders-Active Silica Micropowder Complete Device "is stable in high-strength, high-performance and durable concrete structures. Ensure the normal maintenance and operation of each separation device for 10 years.

17. technical safety

The Green Industry New Technology and New Materials Project is an environmental protection industry pollution control project aimed at the smelting and metallurgical industry. In order to eliminate the embarrassing situation that smelting waste dust and metallurgical waste residue are difficult to recover and landfill disposal, technical services are used to promote market development and form zero Emission conversion technology produces a new material-activated silica powder, promotes the market use of new materials without secondary pollution and market acceptance. As a new material, it has been widely used in concrete projects of major national key projects.

18. Barriers to technology transfer and promotion

Local government policy support is insufficient (such as tariffs, subsidies, etc.), financing difficulties, high investment costs or long investment payback periods.
