Shandong Haihua Environmental Protection Equipment Co., Ltd. is mainly engaged in mining fans, mine fans, main fan fans, mining fan fans, coal mine fans. Introduce you to the application of mining fans in the industrial field.
First, the boiler fan
Boiler fan can choose centrifugal or axial flow according to the specifications of the boiler. According to its function, it is divided into boiler ventilator-to send air to the boiler; boiler induced draft fan-to extract the flue gas from the boiler.
Ventilator for ventilation
This type of fan is generally used for ventilation and heating and ventilation of factories and various buildings. The pressure is not high, but the noise requirements are low. Centrifugal or axial flow fans can be used.
3. Fans for industrial furnaces (chemical iron furnaces, forge furnaces, metallurgical furnaces, etc.)
This type of ventilator requires high pressure, usually from 2940 to 14700N / m2, which is the range of high-pressure centrifugal ventilator. Because the pressure is high and the peripheral speed of the impeller is large, the impeller should have sufficient strength during design.
Fourth, the mine fan
It has two types: one is the main ventilator (also called the main fan), which is used to deliver fresh air to the well, and its flow is large, and the axial flow is more suitable, and the centrifugal is also useful; the other is local ventilation Machine (also known as local fan) is used for ventilation of the working face of the mine. Its flow rate and pressure are small, and explosion-proof axial flow fans are mostly used.
Five, pulverized coal fan
Centrifugal fans are mostly used to transport coal powder in the boiler combustion system of thermal power stations. The pulverized coal fan can be divided into two types according to different uses: one is the silo type pulverized coal fan, which blows the pulverized coal in the storage bin from its side into the furnace. The pulverized coal does not directly pass through the fan. The fan is required. The exhaust pressure is high; the other is a direct blown pulverized coal fan, which directly sends pulverized coal to the furnace. Because pulverized coal wears heavily on impellers and body shells, abrasion-resistant materials should be used.
