Abstract

The invention discloses a continuous preparation apparatus and method of a slag porous material. The apparatus comprises a slag melting furnace, a slag discharging device, a rapid hardening forming machine, a fixed-size cutting machine, a conveying track, and an annealing furnace which are connected in a process flow order; the slag melting furnace is provided with an auxiliary agent spray gun, a coal oxygen spray gun, a foam stabilizer spray gun for respectively spraying auxiliary agents, coal oxygen, and foam stabilizers; coal oxygen burns to maintain the temperature of the slag, and to allow the auxiliary agents and the foam stabilizers to melt rapidly and to be homogenized, and thus the hot-melt slag becomes foaming slag; the foaming slag is continuously injected into the rapid hardening forming machine for cooling and is prepared into the slag porous material. The invention also discloses a continuous preparation method of the slag porous material, which comprises: delivering hot-melt slag into the slag melting furnace, spraying the auxiliary agents, the foam stabilizers and coal oxygen to form foaming slag, continuously injecting the foaming slag into the rapid hardening forming machine for rapid cooling so as to prepare the slag porous material, or continuously injecting the foaming slag into a casting die to prepare the slag porous material. According to the invention, high heat energy of the hot-melt slag is made high-efficient use of, and the slag porous material with a high added value is produced; the economic benefit is increased, and the effects of energy saving and emission reduction are significant.
