China Salt-Kunshan joint innovation and development have yielded fruitful results

　　Recently, it was reported from China Salt Kunshan Co.
, Ltd.
that from January to May, the company achieved an operating income of 1.
365 billion yuan, a year-on-year increase of 67.
48%.

.
At the moment of the new crown pneumonia epidemic, the company's impressive performance is mainly due to the results of continuous technological innovation, safe and stable operation, and grasping market opportunities
.

　　By cooperating with colleges and research institutions, hiring academicians, and introducing talents, China Salt Kunshan has built a new cooperative innovation platform - Jiangsu Enterprise Academician Workstation, created a leading technological innovation system in the soda ash industry, and developed and implemented a number of leading technological innovations.
, safety, environmental protection, low-carbon and energy-saving projects, which have a demonstration and leading role in China's soda ash industry
.

　　After the completion of the relocation and construction of the soda ash project with an annual output of 600,000 tons, the company has achieved remarkable scientific and technological achievements through continuous technological innovation
.
China Salt Kunshan cooperated with Academician Zhou Guangyao of the Chinese Academy of Engineering to establish an academician workstation.
The project of "Design, Development and Application of Three-stage External Cooling Carbonization Tower" won the first prize of Science and Technology Progress of China Soda Ash Industry Association in 2019-2020; "Dry Ammonium Exhaust Gas" The "Environmental Protection Governance" project was developed and implemented for the first time in China's soda ash industry, opening a new model of joint technology research and development between enterprises, universities and design institutes
.

　　In 2016, the company used light ash powder flow cooler technology to develop a new cooling process for light ash products, with a cooling capacity of 37.
5 tons/hour of light ash
.
This process solves the problems of low heat transfer efficiency, large floor space, high energy consumption, high maintenance cost, dust pollution and other problems associated with the traditional cooling method of light ash products in the soda ash industry.
The discharged light ash is cooled to 70 ℃, which not only meets the requirements of cooling light ash, but also saves electricity and reduces the discharge of alkali powder, so as to achieve the purpose of energy saving, emission reduction and production optimization
.

　　In January 2020, the three-stage external cooling carbonization tower (10# tower) produced and operated by China Salt Kunshan, the single tower capacity of the combined alkali method can reach more than 300 tons/day
.
This technology was jointly developed by Academician Zhou Guangyao, China Salt Kunshan and China Soda Ash Industry Association, and under the guidance of Academician Zhou Guangyao, China Salt Kunshan made a major breakthrough in the technological innovation of soda ash carbonization system
.
By improving the cooling structure of the conventional external cooling carbonization tower, the quality of sodium bicarbonate particles in the carbonization effluent is the best, and the innovative technical goal of "direct centrifuge separation of the carbonization effluent" is achieved
.
The carbonization towers all use high-efficiency sieve trays, and the tower absorption efficiency is high.
When the tower production intensity reaches 1 ton/m3·day, the average concentration of carbon dioxide in the tail gas of the soda tower is less than 5%
.

　　In addition, the company's "dry ammonium tail gas environmental protection treatment" project uses a combination of water washing and acid washing to solve the problem of waste gas treatment in the soda ash industry
.
The project improves the comprehensive utilization level of resources, reduces the ammonia concentration in the exhaust gas discharged from the alkaline boundary area, and the ammonia content of the exhaust gas is less than 100ppm, which is far lower than the current national standard value
.

　　Up to now, China Salt Kunshan has more than 10 scientific research achievements with independent intellectual property rights, and has won the Science and Technology Progress Award of China Soda Ash Industry Association and the Technology Innovation Award of China Inorganic Chemical Industry Society for 6 consecutive years
.
In addition, the company is also the "Benchmarking Enterprise of Energy Consumption Leader in China's Soda Ash Industry" announced by China Petroleum and Chemical Industry Federation
