In 2013, China released many policies relating to environmental protection, increasing emission standards and supplying more subsidies for using dust-collecting equipments in coal and electric power enterprises. Many favorable factors accelerate the growth of domestic dust-collecting equipment market. In 2013, the market scale of dust-collecting equipments in China registered CNY 38.897 billion, up 17% year-on-year. Seen from the products, at present, the mainstream equipment in China’s dust-collecting equipment market is mainly concentrated in the three major types of products, namely electrostatic precipitators, bag-type dust collectors and electrostatic & bag composite filter.. By 2013, there were about more than 500 enterprises engaging in the dust-collecting equipment in China, including about 320 related enterprises engaging in the manufacturing of bag-type dust collectors and remaining more than 200 enterprises mainly engaging in the manufacturing of electrostatic precipitators. At the end of 2013, the total output value of bag-type dust collectors in China reached CNY 23.65 billion, accounting for 55.94% of the dust-collecting equipment’s total output value. As the emission standards and requirements on industries such as thermal power, cement, garbage harmless treatment and steel melting increased, high-temperature soot emission treatment industry is bound to obtain rapid growth, while bag-type dust-collecting technology has excellent performances in efficiency of dust collection, decreasing application cost, as well as its application in large-scale machines has been mature gradually and application scope expanded continuously, thus it tends to develop fast without a doubt.
