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

[0045] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0046] Such as figure 1 , Figure 5 As shown, a blast furnace hot slag granular cotton production line includes a blast furnace slag ditch for diverting blast furnace hot slag, a slag furnace, a centrifuge 5, a cotton collector and a granulator, wherein the centrifuge, cotton collector Machine and granulator are common equipment in the prior art. The slag furnace includes a feeding pool 1, a homogenizing pool 2, a melting pool 3 and a forehearth 4 in sequence. The upper part of the feeding pool is provided with a slag inflow port 11 and a main conditioning material feeding port 12 .

[0047] The blast furnace slag ditch includes drainage slag ditch 1a, water slag ditch 1c and slag extraction ditch 1b. The side of the drainage slag ditch is provided with a slag-taking gap. The slag taking gap is close to the hot slag outlet end of the blast ...

Abstract

The invention discloses a blast furnace thermal-state slag granular cotton production line and aims to provide the blast furnace thermal-state slag granular cotton production line 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 cotton to be improved. The device includes a blast furnace slag trough used for guiding a blast furnace thermal-state slag flow, a slag furnace and a centrifugal machine. The slag furnace successively includes a feeding tank, a homogenizing tank, a melting tank and a material path. 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. One end of the material path is communicated with the melting tank and the other end of the material path is closed. In addition, a material outlet port is arranged at the bottom of the material path.

Description

technical field [0001] The invention relates to the field of mineral wool production, in particular to a blast furnace hot slag granular cotton production line. 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, which i...
