Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0056] like figure 1 As shown, a blast furnace hot slag mineral wool preparation system includes a slag taking ditch 1a for diverting the blast furnace hot slag, a slag furnace and two or three or four centrifuges. There are two centrifuges in this embodiment.

[0057] like figure 1 , figure 2 , image 3 As shown, the slag furnace includes a charging pool 1, a homogenization pool 2, a melting pool 3, a purification pool 4 and two or three or four forehearths 5 in sequence. There are two forehearths in this embodiment. The number of centrifuges corresponds to the number of channels (ie the same). The bottom of the feeding tank and the bottom of the homogenization tank are connected through the first liquid flow channel 7 . The bottom of the homogenization tank and the bottom of the melting tank are communicated through the seco...

Abstract

The invention discloses a blast furnace thermal slag-to-mineral wool preparation system, and aims to provide the blast furnace thermal slag-to-mineral wool preparation system that not only can make full use of the residual heat resources in blast furnace thermal slag, is environment-friendly, but also can achieve uniform melt melting in a slag melting furnace and high vitrification degree, and effectively improve the fiber forming rate and quality of mineral wool. The system includes: a slag fetching ditch for diversion of blast furnace thermal slag, a slag melting furnace and at least two centrifuges. The slag melting furnace comprises, in order, a charging pool, a homogenization pool, a melting pool, a purification pool and at least two material channels. The upper part of the charging pool is provided with a slag inflow port and a main tempering material adding port. The bottom of the charging pool and the bottom of the homogenization pool are connected through a first liquid flow channel, the bottom of the homogenization pool and the bottom of the melting pool are communicated through a second liquid flow channel, and the purification pool and the melting pool are communicated through a third liquid flow channel. One end of each of the material channels is communicated with the purification pool, the other end is sealed, and the bottom of each material channel is provided with a discharge port.

Description

technical field [0001] The invention relates to the field of mineral wool production, in particular to a blast furnace thermal slag mineral wool preparation system. Background technique [0002] Mineral wool uses industrial waste slag (blast furnace slag, etc.) Under the action of the centrifugal force generated by the roller, it is thrown into mineral wool fibers; at the same time, the mineral wool fibers are blown into the cotton collector with the high-speed airflow ejected from the wind ring in the centrifuge (the high-speed airflow ejected from the air ring is on the centrifugal roller shaft. Upward, high speed flow along the surface of the centrifugal roller). The mineral wool fiber in the cotton collector gathers on the mesh belt of the cotton collector under the action of negative pressure wind suction to form a mineral wool felt. Mineral wool has the characteristics of light weight, small thermal conductivity, non-combustible, moth-proof, cheap, corrosion-resistan...
