The invention discloses a hot blast furnace device for blast furnace ironmaking, including a furnace body. A furnace grate is installed at the bottom of the inner wall of the furnace body, a cold air pipe, an exhaust pipe and a hot air pipe are installed on the side wall of the furnace body, a regenerator is provided in the middle of the furnace body, the top of the furnace body is connected with a vault through a connecting body, a regenerator is filled with a regenerative ball in the heat storage chamber, and the connection body includes a ring. The inner wall of the ring wall is connected with a jetting device through a connecting pipe. The outer wall of the ring wall is uniformly installed with three pipes through the gas port. A number of burner is fixed on the side of the burner and the inner wall of the ring wall, and a number of air guide plates are installed on the inner wall of the three pipe, and the gas is evenly dispersed to each burner through the three three pipe and guide plate. The burner has longer service life, the heat of the regenerator is promoted quickly by the joint fire of the burner and the ring wall, which saves the heat of the regenerator, and saves the heat storage time, and the burner is slanted down and spout, the life of the vault is longer, the regenerator is regenerative with the heat storage ball, the heat storage efficiency is high, and the hot air production is faster.

一种高炉炼铁用热风炉装置
本专利技术涉及热风炉
,具体为一种高炉炼铁用热风炉装置。
技术介绍
热风炉是为高炉加热鼓风的设备,是现代高炉不可缺少的重要组成部分。现代大高炉目前最常用的是蓄热式格子砖热风炉,蓄热式热风炉按燃烧方式可以分为顶燃式,内燃式,外燃式等几种。由于顶燃式热风炉性能好,热传导效率高,因此,现在顶燃式热风炉最受大型高炉炼铁场欢迎。现有的存在以下不足之处和问题:(1)现有的顶燃式热风炉的炉壁上安装有一个煤气管和一个助燃空气管,在共同进气的时候,由于进气处于不同边,进气后煤气和空气容易混合不均匀导致有的烧嘴火焰大,有的烧嘴火焰小,喷出火焰大的烧嘴寿命会大大降低,且由于与煤气进口处的烧嘴的燃气密度大,所以靠近煤气进口的烧嘴喷出火焰大而易损毁;(2)现有的顶燃式热风炉大多数都是炉壁的内壁垂直安装的烧嘴喷烧燃气而对传热给蓄热体,由于烧嘴个数和燃烧面积较小,燃烧热量的速度和温度都大大减小,蓄热体加热较慢,且拱顶和蓄热体收到的热量几乎相等,拱顶寿命不长;(3)现在的热风炉大多数蓄热体采用格子砖蓄热,但是由于格子砖与烧嘴喷火产生的热量的直接接触面积只有顶面,因 ...
