Problems solved by technology

Since blast furnace slag is widely used, the principle of energy recovery of slag is not only to recover residual heat resources, but also to facilitate the reuse of slag. While making full use of the sensible heat of waste slag, produce mineral wool, slag glass ceramics, etc. Building material products with high added value; but at present, most blast furnace slags at home and abroad are mainly water-quenched, and the heat cannot be recycled

Embodiment Construction

[0048] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0049] Such as figure 1 , figure 2 , image 3 As shown, a blast furnace hot slag mineral wool production equipment includes a slag ditch 1a for guiding blast furnace hot slag, a feed chute device 1b, a slag furnace and two or three or four centrifuges ; Wherein the centrifuge is a common equipment in the prior art. There are two centrifuges in this embodiment.

[0050] Feeding chute device 1b comprises chute support 2b, is arranged on the chute body 3b on the chute support, is arranged on the feed chute 4b on the top surface of the chute body and is arranged on the chute support, is positioned at the loam cake 5b above the feed chute. The cross section of the chute support is U-shaped. The chute support consists of a base 2b1 and two supporting side plates 2b6 parallel to each other arranged on the opposite sides of the base. The chute bo...

Abstract

The invention discloses a blast furnace thermal-state slag mineral wool producing device and aims to provide the blast furnace thermal-state slag mineral wool producing device which not only can fully utilize residual heat resources in blast furnace thermal-state slag and is energy-saving and environmental-protective but also can enable a melt in a slag furnace to be melted uniformly, a vitrification degree to be high and a fiber-forming ratio and quality of mineral wool to be improved. The device includes a slag-obtaining trough used for guiding a blast furnace thermal-state slag flow, a feeding chute apparatus, a slag furnace and at least two centrifugal machines. The slag furnace successively includes a feeding tank, a homogenizing tank, a melting tank, a clarifying tank and at least two material paths. A slag flow inlet and a main modulating material feeding port are arranged on an upper part of the feeding tank. The bottom of the feeding tank is connected to the bottom of the homogenizing tank through a first liquid flowing path. The bottom of the homogenizing tank is communicated with the bottom of the melting tank through a second liquid flowing path. The clarifying tank is communicated with the melting tank through a third liquid flowing path. One end of each material path is communicated with the clarifying tank and the other end of each material path is closed. In addition, material outlet ports are arranged at the bottoms of the material paths.

Description

technical field [0001] The invention relates to the field of mineral wool production, in particular to a blast furnace thermal slag mineral wool production equipment. Background technique [0002] With the rapid development of the global economy, the problem of energy shortage is becoming more and more serious, and the technology of energy saving and emission reduction has become a research hotspot all over the world. At present, my country's energy situation is severe, and the product energy consumption index is too high. The energy consumption per unit of the main energy-consuming products is 25-90% higher than that of developed countries (the weighted average is about 40% higher); secondly, the energy consumption of the output value is high. Energy consumption is one of the highest in the world. For example, for every kilogram of oil equivalent of energy, Japanese companies can create an average output value of 10.2 US dollars, while China can only create 0.7 US dollars, w...
