On the same day, the head of the investigation team for the explosion of the special major incident in jiangsukunshan metals products ltd., and director-general of the national security inspectorate, yang zheng liang, stated that, based on the problems revealed and the initial knowledge of the incident, there had been a long-standing failure to resolve the business problems and the risks involved, the concentration of dust exceeded standards and the explosion of fire sources was a major liability incident。
At the plenary meeting of the group, yang zheng liang identified a number of factors that gave rise to the accident. Journalists found that the de-dustor equipment was not designed as an independent vacuum cleaner for each job as required, and that the removal capacity was insufficient; that all electrical equipment in the workshop was not equipped to comply with blast-proof requirements; and that the lack of fire-retarding and static electrical maintenance supplies, among other things, was of great concern to the outside world。
Against this background, the issue of specialized anti-dust equipment for industrial enterprises, future developments in the market for such equipment and the current situation of enterprises producing such equipment have attracted wide external attention。

In jiangsukunshan, the “8. 2” explosion caused enormous casualties, prompting outside attention to dust explosions, while issues related to specialized anti-dust equipment were visible to the outside world。
Dust explosions are known to be a safety hazard in many industrial areas. Xinhua quoted german media reports that even in the developed regions of europe and the united states, many dust explosions of different sizes occur every year. Between 1980 and 2005, more than 100 people were killed and over 700 injured as a result of recorded dust explosions in the united states。
It is known that, at the end of may 2011, the general directorate for the supervision of national security production issued a public circular to the general directorate for the control of national security production on further strengthening of the prevention of dust explosions in commercial and industrial enterprises, such as metallurgy, indicating that the general directorate for the control of national security production requested that a special inspection be carried out as soon as possible for the safe production of dust work projects, stating that, in conjunction with the characteristics of the hazardous sites of the enterprise's own dust explosions, facilities such as ventilation, dust removal, lighting, detection and fire protection against explosions should be equipped. In addition, the circular requires the enterprises concerned to carry out immediately a special safety check and an assessment of the effectiveness of safety measures, such as the engineering design of the dust work project, the production processes, the production chain, the various production units and the management of safe production, all of which do not meet the requirements for safe production, and to stop and correct production。
Journalists have learned that the main methods of dust removal in the production process in domestic industrial enterprises are currently electric and bagging. The advantages and disadvantages of the two previous approaches had been controversial, but the demand for equipment and upgrading of the two means of de-dusting had been perceived as driving the entire industry rapidly。
Yang, the chief economist of information, told hong that the “8-2” bombing in quinshan had attracted the attention of the state and that the regulatory authorities' requirements for safe production in dust-producing enterprises would be tightened and would contribute directly to the development of the dust removal industry. “the clean-up industry market can reach at least 100 billion levels in the next five years. Upgrading of ff and esp will be the main growth point for the industry.”
Market size will be hundreds of billions
Over the past two years, environmental protection has been a focus of attention, as has the increasing investment of my government, society and business in environmental governance. According to the data, the annual rate of investment in the environmental sector has remained above 15 per cent since the fifteenth and total investment in the environmental sector during the eleventh five-year period amounted to 1. 375 trillion, an increase of 96. 4 per cent over the fifteenth period and a rise to 1. 35 per cent of GDP。
It is believed that, with policy impetus, the country's environmental industry will continue to grow at a composite rate of 15-20 per cent per year for the coming period, with a projected value of 2 trillion yuan for the 12-50 period and becoming the backbone of the national economy by 2020。
Against the backdrop of rapid increases in environmental inputs, haze, pm2. 5 etc. Have become the subject of high public attention, and air pollution, dust management, etc. Have become a top priority. Dust removal equipment, as one of the main equipment manufacturing products to control atmospheric pollution, is considered to have a wide market outlook。
In the last two years, our standards for atmospheric emissions of pollutants in the cement, pyrotechnic and iron industries have been raised, but the standards for emissions of soot in industries such as cocal, electrolytic aluminium, aluminium oxide, iron alloys, carbon materials and ceramics are still somewhat different from those in place in the european and american countries, and industry believes that in the future they will be more stringent。
According to liu weiping, secretary-general of the electronic dust demolitions commission of the chinese environmental protection industry association, the development of the dust removal industry is currently strongly influenced by policy, and the upgrading of emission standards will contribute rapidly to the upgrading of the industry。
Yang pointed out to hong that there was a large market for the waste removal industry, but that there was still a gap between the current state of development and expectations. “i have travelled to many enterprises that produce dust in the production process, some of which do not have dust removal equipment to save costs.”
“the quinshan bombing was a warning to the regulations.” according to yang, “in the context of our growing interest in environmental protection, the regulation of the removal of dust from industrial enterprises will be increasingly stringent, which will lead directly to the development of the industry. For a maximum period of five years, the market for the dust removal industry can reach a trillion yuan”。
Guo peng, a wide-scale securities analyst, is more optimistic, arguing that the market could reach $12 billion over the next five years, in terms of the adaptation of the de-dusting equipment alone。
"technology" currently contests/
It is understood that, at present, in the field of industrial dust removal, the users of this equipment are mainly manufacturing enterprises such as fire, steel and cement, and that two types of governance techniques — electrical dust removal and bagging — are available. Over the past two years, there has been debate within the industry as to which of the two types of governance technologies are more appropriate to the needs of domestic firms。
According to the data, in 2012 the value of esps was about 17 billion yuan and that of fsps about 14 billion yuan. In addition, the majority of the production of bagging equipment is small and medium-sized enterprises。
Liu weiping noted the advantages and disadvantages of esp and fsp and that it was difficult to distinguish between these two techniques directly by virtue of the current national emission standards。
It is understood that electric dust removal is characterized by low resistance, low electricity consumption, high automation, high temperature adaptability and resistance to corrosion, and that current electro-dust removal technologies are more mature than bagging, with relatively low investment costs and low maintenance and operation costs. Pumpkin equipment is characterized by small, flexible size, high dust removal efficiency and simple operation management, but with the same processing capacity, initial investment is high and maintenance costs for large-scale pumpkin equipment are difficult for many small enterprises to absorb. The data show that the filter life of the bag is 2-3 years, and that replacement of a bag every 3 years can cost millions of dollars for the large bag。
“both approaches apply to enterprises in need of dust removal in the country.” liu weiping told the daily economic news reporter that “enterprises need to evaluate which one is suitable according to their own production and the characteristics of both technologies. The reason for the debate about which method is better is that industry has different understandings of technology。
Yang pointed out that, in the current environment, there was a rapid expansion of the application of bag cleaners, but that there was still considerable space for the application of electric scrubbers, both of which were promising。
“non-metal powders need to be adsorbed with bags of equipment, while the current size of the non-metal powder industry in the country is much larger than that of metal powder. From this point of view, it can be said that there are better prospects for bagging.” yang told the journalist。
Liu weiping, for his part, believes that the biggest problem with the current method of electrical dust removal is that the old esp does not meet the new standards. “the investment required to replace the equipment is significant and the enterprise is therefore more willing to upgrade its old esp. There are currently tens of billions of market spaces available for the refurbishment of electrical dust removal equipment”。
“the enterprises that had previously had to dedust themselves were unwilling to invest in money, the society was not aware of its harmful effects and government regulation was inadequate。
