The market demand for fan products has a promising future

With the rapid development of my country's economy, especially the sustained and stable development of the machinery industry in recent years, it has brought rare development opportunities to the fan industry. Fan products are one of the most widely used products in various sectors of the national economy. According to investigations by relevant departments, the proportions of fan products used in the main industries are: construction accounts for 38.08%, environmental protection accounts for 15.93%, light industry accounts for 7.52%, metallurgy accounts for 6.79%, mining accounts for 6.67%, ships account for 4.58%, cement Accounted for 3.96%, electricity accounted for 3.87%, subways and tunnels accounted for 3.79%, textiles accounted for 2.95%, coal accounted for 2.26%, chemical industry accounted for 2.21%, petroleum accounted for 1.28%, air separation plant accounted for 0.1%.

   However, there are still many fields that fan products have not yet or will be involved in, that is, the potential market for fan products. So, what are the potential markets for fan products, and how much demand is there for fan products in these markets? It is understood that the demand for fan products in the following areas will increase significantly in the next few years.

   Comprehensive utilization of coal gangue

   In the past, coal gangue was separated from coal and piled up as waste, not only occupying open space, but also affecting the environment. Turning coal gangue into waste is used to generate electricity. For example, Anhui Huaibei Mining Group Company plans to equip two 75-ton/hour circulating fluidized bed boilers, using 240,000 tons of coal gangue and 100,000 tons of low-quality coal. The annual power generation is expected to reach 144 million kilowatts/hour, and boiler fans are required. 6 sets. Similarly, Huozhou Coal and Electricity Group also intends to use coal gangue to generate electricity, and it is estimated that 18 ventilators will be needed.

   New dry process clinker technological transformation project

   The cement industry will eliminate outdated wet kilns and adopt advanced technology to build a clinker production line with a daily output of 2,000 tons. After the transformation, each production line can produce 680,000 tons of high-grade cement annually. The heat consumption of clinker sintering will be reduced from the current 6294 kJ/kg to 3262 kJ/kg, the comprehensive electricity consumption per ton of cement will be reduced to 110 kW/h, and the emission concentration of kiln exhaust gas dust will be reduced to less than 100 mg per standard cubic meter. . The project can increase production and reduce consumption, and meet environmental protection requirements. Each production line requires a total of about 25 fans.

   flue gas desulfurization

  The exhaust gas produced by the boiler of a thermal power plant contains a large amount of sulfur dioxide, which causes pollution to the atmosphere. The serious pollution is acid rain. Therefore, thermal power plants must be equipped with desulfurization devices. The old thermal power plants are not equipped with desulfurization devices and all need to be modified. For example, the North China Electric Power Group Corporation Tangshan General Power Plant plans to adopt limestone-gypsum wet desulfurization technology to implement flue gas desulfurization transformation for 300,000 kilowatt units. After the transformation, the desulfurization efficiency is greater than 95%, and the annual emission of sulfur dioxide is reduced by 12,732 tons and the soot is 4,774 tons.

  The flue gas desulfurization device requires a desulfurization fan. Because sulfur dioxide gas is very corrosive, the difficulty of the desulfurization fan lies in the corrosion resistance of the material, and even the impeller needs to be lined with rubber to prevent corrosion. There are many power plants in the country that require desulfurization transformation; with the rapid development of the national economy, many areas have already experienced insufficient power supply, and new power plants must be built, and new power plants must be equipped with desulfurization devices. Therefore, the potential market for desulfurization fans is relatively large.

   Waste Incineration Cogeneration

   With the increasingly stringent requirements for environmental protection, municipal waste treatment is not limited to sanitary landfill and waste composting. It has now developed to use the heat generated by waste incineration to generate electricity, the so-called waste incineration combined heat and power. According to statistics, each set of this device requires 6 fans, and the project is currently needed in various places, so the potential market in the country is very large.
