Mine well head antifreezing equipment
"Coal mine safety regulations" (2006 Edition) 102nd stipulates: "the air temperature below the intake shaft (dry bulb temperature, the same below) must be above 2 C." In the north of China, in North China, especially north latitude 37 degrees north, the winter temperature is below 0 C, the duration is longer, the most cold Greater Khingan Range area, the lowest temperature is below -25 C for 4 months. Therefore, if the coal mine should be produced according to the requirements of the coal mine safety regulations, the coal mine ventilation and heating equipment must be added, and the coal mine is used. Coal fired hot blast stove is widely used because of its convenient installation and use and high thermal efficiency. At present, in order to ensure the safety of coal mine ventilation system, the operation mode of positive pressure air supply and negative pressure is required, and the air side and the smoke side are absolutely closed, and no mutual leakage is found. Henan Tai Pan Boiler Manufacturing Co., Ltd. and Xi'an Jiaotong Co., Ltd., China Shipbuilding Heavy Industry Group Co., Shanghai Industrial Boiler Research Institute, China University of Mining and Technology. Joint (according to the national standard GB50215-2005) development and design of a new generation of heating products - high. Low temperature hot air furnace to fill the domestic empty. Hot blast stove, coal mine hot stove, food hot-air stove, drying hot stove, Taikang boiler plant in Henan province is the drafting unit of National hot blast stove. The high efficiency coal fired hot blast stove produced by the Taikang boiler plant in Henan Province, the coal mine hot blast stove uses the air as the heating medium, uses the multi head spiral groove plate heat exchange and the turbulent flow technology, the laminar flow phenomenon, makes the air and the flue gas exchange the rotation direction continuously in the marching, strengthens the heat transfer effect, has the advantages of fast heating speed, convenient installation, reliable use and so on. All indicators of hot stove reach the leading level in China. The hot air stove is especially suitable for the underground heating in coal mines, and can also be used for heating and heating in the workshops, the theater of the workshop and other places, and is used to dry the materials with all kinds of drying equipment.
