钢管式空气预热器的防磨装置制造方法及图纸
一种钢管式空气预热器的防磨装置,它涉及现代锅炉中空气预热器领域。本实用新型专利技术为了解决现有的钢管式空气预热器存在钢管抗磨损性能差,烟气对钢管的冲刷磨损严重,空气预热器使用寿命短的问题。本实用新型专利技术的多个防磨套管(3)均为空心圆柱形管体,每个防磨套管(3)的下端均通过焊接的方式与每个钢管式空气预热器钢管(1)的上端连接,多个防磨套管(3)之间浇筑耐火混凝土(4),多个防磨套管(3)的外径均与钢管式空气预热器钢管(1)的内径相同。本实用新型专利技术专利提供一种钢管式空气预热器的防磨装置,有效地减轻烟气对钢管的冲刷磨损,增加钢管式空气预热器的使用寿命。本实用新型专利技术布置在钢管式空气预热器向烟面的管板上。
Anti grinding device for steel tube type air preheater
The utility model relates to an anti grinding device for a steel tube type air preheater, which relates to the field of an air preheater in a modern boiler. The utility model solves the problems that the existing steel pipe type air preheater has the advantages of poor abrasion resistance of the steel pipe, severe erosion of the flue gas on the steel pipe and short service life of the air preheater. The utility model has a plurality of anti-wear sleeve (3) is a hollow cylindrical tube, each anti-wear sleeve (3) at the lower end of the through steel pipe welding and each pipe type air preheater (1) connected to the top, a plurality of anti-wear sleeve (3) between pouring refractory concrete (4), and more a wear sleeve (3) and the outer diameter of a steel tube type air preheater (1) of the same diameter. The utility model provides an anti abrasion device of a steel tube type air preheater, effectively reducing the erosion and abrasion of the flue gas on the steel pipe, and increasing the service life of the steel tube type air preheater. The utility model is arranged on the pipe plate of the steel pipe type air preheater toward the smoke surface.
