Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as figure 1 As shown, a liquid slag heating recycling device includes a cyclone furnace 1, a supplementary heating furnace 2 and a slagging heating furnace 3, the supplementary heating furnace 2 is arranged directly under the cyclone furnace 1, and the slagging heating furnace 3 It is arranged below the supplementary heating furnace 2; the supplementary heating furnace 2 includes a vertically arranged cylindrical supplementary heating furnace body 203, the supplementary heating furnace body 203 is made of thermal insulation material, and the upper end of the supplementary heating furnace body 203 is a supplementary heating furnace The slag inlet 201, the lower end is the slag outlet 202 of the supplementary heating furnace. The slag inlet 201 of the supplementary heating furnace corresponds to the slag outlet of the cyclon...

The invention relates to the technical field of liquid-state furnace slag heating and recycling, and concretely relates to a liquid-state furnace slag heating and recycling device, which comprises a cyclone furnace, a concurrent heating furnace and a deslagging heating furnace. The concurrent heating furnace comprises a vertically arranged cylindrical concurrent heating furnace body; a concurrentheating element for heating fallen furnace slags is arranged in the concurrent heating furnace body; and a concurrent heating furnace chamber for the furnace slags to pass through is arranged in the concurrent heating element. Compared with the prior art, according to the liquid-state furnace slag heating and recycling device provided by the invention, the heating furnace is arranged on a slag hole of the cyclone furnace so as to be used for heating, so that the problem that solid-state molten slags are formed on the slag hole of the cyclone furnace can be effectively solved, and the discharged slags are prevented from being caked; then through controlling the temperature of the heating furnace, the furnace slags from the slag hole to delivery equipment are almost all maintained as liquid-state furnace slags with the required viscosity for the next-step recycling, so that the further recycling of the furnace slags is well prepared; and the liquid-state furnace slags can be directly used as raw materials for manufacturing other industrial products without the need for double heating, so that the energy is saved, an operation environment is remarkably improved, and the production efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of heating and recycling of liquid slag, in particular to a device for heating and recycling of liquid slag. Background technique [0002] The cyclone furnace is a device that uses the high-speed rotating air flow to rotate and burn the combustion particles at high speed, and most of them are used for the treatment of solid waste. The heat of the cyclone furnace after combustion can be used to heat the boiler, and the superheated steam generated by the boiler Power generation, and the solid waste after being burned by the cyclone furnace forms high-temperature molten slag, the temperature can reach about 1400-1500 ° C, most of the molten slag is dropped by the hot air into the molten pool at the lower part of the inner wall of the cyclone furnace, and the melting in the molten pool The slag flows out through the overflow port, and the outflowing molten slag flows out of the cyclone furnace in the form of liq...
