In 2021, the global new crown epidemic will recur, and economic development will be full of uncertainties. In the first half of the year, raw material prices have been rising, terminal sales have been sluggish, and exports have suffered "Waterloo"... The construction and ceramics industry has been hit hard, and it has affected upstream and downstream industries.
In this context, Jiangxi Lanyu Environmental Co., Ltd. (hereinafter referred to as "Lanyu Environmental Protection") is still experiencing rapid development, and several flue gas treatment projects in multiple production areas are under construction at the same time!
National/landmark environmental protection policies are tightened
Ceramic companies pay more and more attention to environmental protection
On May 31, 2021, the National Development and Reform Commission issued the "Guiding Opinions on Strengthening the Prevention and Control of Ecological Environment Sources of High-energy-Consumption and High-Emission Construction Projects", clarifying that "two high" projects are temporarily classified as coal power, petrochemicals, chemicals, and steel. According to the statistics of six industry categories including , non-ferrous metal smelting and building materials, as an important part of the large building materials industry, the ceramic industry has also officially entered the "Two Highs".
In fact, terminal flue gas treatment in the ceramics industry has long been put on the agenda. "Ceramic Information" reviewed the information and found that the "Pollutant Emission Standard for the Ceramic Industry" (GB25464-2010) was officially released in 2010 and attracted widespread attention.
In 2013, environmental protection issues in the construction and ceramics industry have evolved into a national issue. Local governments in China have continued to tighten supervision of environmentally friendly production. Incidents of "one size fits all" environmental protection policies have occurred from time to time. Controversies caused by new standards are endless.
Until 2014, the "Environmental Protection Law of the People's Republic of China" was promulgated, setting off a nationwide environmental protection storm. The urgency of environmental protection and green production in the building ceramics industry has greatly increased. At that time, the 2014 revision of the national standard was also issued, requiring the baseline oxygen content of spray drying towers and ceramic kiln flue gases to be 18%, particulate matter 30mg/m³, sulfur dioxide 50mg/m³, and nitrogen oxides 180mg/m³.
Currently, my country's current air pollutant emission limits for the ceramic industry comply with the "Porcelain Industry Pollutant Emission Standards" (GB 25464-2010) and its 2014 revision.
At the same time, local governments have repeatedly required the ceramic industry to achieve ultra-low emissions. After tightening local standards, the emission concentrations of particulate matter, sulfur dioxide, and nitrogen oxides in air pollutants are mostly 10mg/m³, 30mg/m³, 100mg/m³ fluctuates up and down.
In 2020, the Ministry of Ecology and Environment proposed in the "Opinions on Resolutely Winning the Battle of Pollution Prevention and Control": Areas with large production capacity in the building materials industry will study and carry out ultra-low emission transformation in cement, ceramics and other industries according to local conditions.
"Ceramic Industry Air Pollution Emission Standards" in various regions
Among them, in June 2019, Guangdong Province issued the landmark "Ceramic Industry Air Pollution Emission Standards", requiring ceramic enterprises in Guangdong Province to implement 20mg/m³ and 30mg/m³ for particulate matter, sulfur dioxide, and nitrogen oxides from July 1, 2020. , 100mg/m³ emission limit.
In August 2020, Hebei Province issued the "Emission Standards for Air Pollutants in the Ceramic Industry". Compared with the national standards, the emission limits for particulate matter, sulfur dioxide, and nitrogen oxides were tightened by 20 mg/m³, 20 mg/m³, and 20 mg/m³, respectively. 80mg/m³.
In May 2021, "Ceramic Information" found that Guangxi, Shandong, Jiangxi Gao'an, Ningxia, Shandong Tai'an, Guangdong Foshan and other places have successively issued new policies and regulations related to the ceramic industry. etc. have put forward new requirements, mainly involving clean production, safe production, ultra-low emissions, etc. Those who violate serious laws and regulations will face penalties such as suspension of production for rectification, or even closure and elimination.
It can be seen that the policies related to air emissions in the national standard and landmark ceramic industries continue to be tightened. For future sustainable development, architectural ceramic production companies are paying more and more attention to "environmental protection management."
The "rapid" development of Lanyu Environmental Protection
Concurrent construction of multiple projects in multiple production areas
Recurrent COVID-19 epidemics, sluggish terminal sales, rising raw material prices, and "Waterloo" exports... The construction and ceramics industry has been affected to a certain extent, and it has affected upstream and downstream enterprises.
Many ceramic companies have slowed down the pace of investment, and few companies are vigorously expanding their territory. Against this development background, Jiangxi Lanyu Environmental Engineering Co., Ltd. (hereinafter referred to as "Lanyu Environmental Protection") is still experiencing rapid development, and several flue gas treatment projects in multiple production areas are under construction at the same time.
According to Zhi Jianghua, chairman of Lanyu Environmental Protection, as of June 30, Lanyu Environmental Protection has multiple environmental protection companies in Jiangxi, Hunan, Xinjiang, Guizhou and other production areas.Treatment projects are under construction in full swing, including dust removal, desulfurization and other environmentally friendly emission treatments.
The simultaneous construction of multiple environmental protection projects in multiple production areas is the best affirmation of Lanyu's environmental protection, especially in the challenging context of the ceramics industry in 2021.
“Thank you to our customers for choosing us, Lanyu!” Zhi Jianghua said. On the one hand, it is the affirmation and recognition of Lanyu Environmental Protection by ceramic enterprise customers for more than ten years. On the other hand, they believe that Lanyu Environmental Protection can provide them with high-quality and stable environmental protection management. plan.
For Lanyu Environmental Protection, the simultaneous construction of multiple projects in multiple production areas also poses certain "challenges". It not only requires production capacity support, but also relies on a professional team for installation and after-sales service.
According to reports, since its establishment, Lanyu Environmental Protection has built a high-quality environmental engineering design, construction, and after-sales service team, and strictly requires the team to standardize environmental engineering, truly solving environmental protection governance and green problems for customers. Production problems.
16 years of persistence
Win customers with hard power
As of 2021, Zhi Jianghua has entered the field of environmental protection management for 16 years. Faced with the tightening of emission standards for the ceramic industry across the country, Lanyu Environmental Protection, headed by Zhi Jianghua, is relatively mature in both process technology and operational management, and can provide companies with complete flue gas treatment solutions.
Lanyu Environmental Protection was established on May 16, 2014. After only a few years of development, Lanyu Environmental Protection’s footprints have spread all over the country. According to reports, Lanyu Environmental Protection has currently undertaken more than 200 environmental protection engineering projects.
Low-key, pragmatic and customer-friendly reputation are the keys to Lanyu Environmental Protection’s achievements today.
As Zhi Jianghua said, "Since entering the field of environmental protection management in 2006, we have come step by step to where we are today, paying close attention to the needs of our customers and committed to solving various flue gas emission management problems for ceramic customers."
Of course, more importantly, Lanyu Environmental Protection’s dust removal, desulfurization, denitrification and other equipment and technologies are excellent!
Taking dust removal equipment and technology in the construction and ceramics industry as an example, currently, the primary technology for controlling particulate matter pollution in ceramic production is bag dust removal technology. At the beginning, the dust removal effect was mainly affected by factors such as poor material of the previous filter bag, poor quality of filter material, high filtration wind speed, excessive resistance, etc. The dust removal effect was not good.
In view of the above shortcomings, Lanyu Environmental Protection has continuously improved, innovated and upgraded its equipment and processes, and selected Flumax (FMS high-temperature composite needle-punched felt) filter bags, combined with a series of film-coated filter materials, are more efficient and have better results.
In terms of desulfurization, after many studies and innovations, Lanyu Environmental Protection currently focuses on two processes: lime-gypsum wet desulfurization and semi-dry desulfurization.
The reaction product of lime-gypsum wet desulfurization is water-insoluble calcium salt, which appears as solid particles in the tower and can be captured under appropriate conditions. The efficient mist eliminator of Lanyu Environment can reduce the dust content to a reasonable range, and after treatment, the sulfur dioxide can also reach the standard. This is the main reason why Lanyu's environmentally friendly lime-gypsum wet desulfurization method is favored by ceramic companies.
According to Zhi Jianghua, semi-dry desulfurization is a new technology that has emerged in the ceramic industry in recent years. Currently, Lanyu Environmental Protection’s semi-dry desulfurization technology is very mature and can meet the current ultra-low emission standards. However, the problem faced by large-scale promotion is: the investment cost is high, and not many ceramic companies can accept it.
In terms of the treatment of flue gas denitrification in ceramic enterprises, Lanyu Environmental Protection has been committed to the selective non-catalytic reduction (SNCR) denitrification technology with relatively low cost and relatively high efficiency. “Because with the current SNCR denitrification technology, Under certain conditions, the emission standard of 100 mg/m³ can be achieved.”
Of course, Lanyu Environmental Protection also has mature technical reserves in selective catalytic reduction (SCR). If ceramic companies have needs, they can also meet their needs!
Green transformation and high-quality development are the main future development directions of the building ceramics industry: not only do we need to save energy and reduce consumption from the source, but we also need to carry out environmentally friendly treatment of flue gas. Zhi Jianghua said frankly that in the future, Lanyu Environmental Protection will continue to innovate flue gas treatment technologies and equipment, and contribute its greatest strength to the stable flue gas emissions of ceramic companies that meet standards.
