It applies, this is because design disclosed in this invention and embodiment are not limited to any embodiment.In addition, disclosed by the invention one
A little aspects can be used alone, or otherwise any appropriately combined be used with disclosed by the invention.
As shown in Figure 1, a kind of device of recycling high-temperature slag heat, described device are used to recycle the molten of the interior outflow of high-temperature smelting pot
The heat of slag 3, described device include slag conveying device 1, molten slag bath 2, lead pool 6, solid slag conveying device 8, protection gas
Device 9, heat-exchanger rig, wherein:The slag conveying device 1 is used to the slag 3 flowed out in high-temperature smelting pot being transported to molten slag bath
2。
The slag 3 is transported to and is connected with molten slag bath 2 for accommodating the slag 3 flowed out out of high-temperature smelting pot by molten slag bath 2
Lead pool 6 in.The height for one side pool side that molten slag bath 2 is connect with lead pool 6 is less than the height of the another side of molten slag bath 2, and
The pond that the pool side height on described one side being connect with lead pool 6 is equal to lead pool 6 is high.It is not required to using the molten slag bath 2 of this structure
Additionally to apply driving force can be delivered to the slag 3 in molten slag pond in lead pool 6, save energy.
Lead liquid 7 is provided in lead pool 6,6 bottom of lead pool is provided with heat-transfer pipe 4, wherein the heat-transfer pipe 4 and lead liquid
Thermal resistance agent 5 is provided between pond 6, the thermal resistance agent 5 is used to heat-transfer pipe 4 and lead pool 6 being connected as an entirety, the heat transfer
It is provided with heat transfer medium in pipe 4.Heat transfer medium is conduction oil.
Heat transfer medium is delivered to heat-exchanger rig by pump.In use, when the heat transfer medium positioned at 6 bottom of lead pool
When absorbing enough heats, which is transported in heat-exchanger rig and exports the heat in heat transfer medium by pump;Work as biography
After the heat of thermal medium is released, which is delivered to the heat that absorption slag 3 is continued in 6 bottom of lead pool by pump.
Since the proportion of lead liquid 7 is 11.2, the proportion of slag 3 is 0.4-1.2.So slag 3 is located at the solid of lead liquid 7
Slag liquid conveying device through 6 solid slag 3 after cooling of lead pool for that will transfer out.
The molten slag bath 2,6 top of lead pool are provided with protection device of air 9, and the protection device of air 9 is used for molten slag bath 2
Protection gas is conveyed with lead pool 6, for preventing slag 3 from being contacted with air.Protective gas is inert gas.
Heat-exchanger rig is connected with the heat-transfer pipe 4 that 6 bottom of lead pool is arranged, for heat transfer medium to be transported to heat-exchanger rig
It is interior.
The operation principle of the device of the recycling high-temperature slag heat of the present invention is as follows:The pyrosol exported in high-temperature smelting pot is logical
It crosses slag conveying device 1 to be input in molten slag bath 2, since the height for the pool side being connected with lead pool 6 in molten slag bath 2 is less than close
The height of slag conveying device 1, so the slag 3 in 3 stove of slag is automatically entered into lead pool 6, due to the lead in lead pool 6
The proportion of liquid 7 is higher than the proportion of slag 3, so slag 3 is located at the top of lead liquid 7, since the bottom of lead pool 6 is provided with heat transfer
The temperature of absorption so heat transfer medium absorbs the temperature of the slag 3 in lead pool 6, and is transmitted to heat exchange dress by medium by pump
In setting, after heat-exchanger rig absorbs the heat in heat transfer medium, heat transfer medium is transferred to by pump in lead pool 6, in lead pool 6
The slag 3 of solidification is exported by solid slag conveying device 8.
By the above technology contents it is found that the present invention recycling high-temperature slag heat device, due to molten slag bath 2 and lead pool 6
The height of one side pool side of connection is less than the height of the another side of molten slag bath 2, and the pool side on described one side being connect with lead pool 6
The pond that height is equal to lead pool 6 is high, so the slag 3 in molten slag bath 2 can be automatically flowed into lead pool 6, improves life
Produce efficiency.
Since the proportion of lead liquid 7 is 11.2, the proportion of slag 3 is 0.4-1.2, so slag 3 and lead liquid in lead pool 6
7 will not mix automatically, can realize layering, so slag 3 can be detached quickly with lead liquid 7.
Due to heat transfer medium by pump be delivered to heat-exchanger rig, when heat transfer medium is after absorbing enough heats, pump
The heat transfer medium in lead night bottom of pond portion is transported to cooling in heat-exchanger rig, heat transfer medium after cooling goes successively to the suction of lead pool 6
Heat is received, so recycles, just the heat transfer of 3 liquid of high-temperature slag is come out, realizes the purpose of cooling.
Although the present invention has been disclosed as a preferred embodiment, however, it is not to limit the invention.Skill belonging to the present invention
Has usually intellectual in art field, without departing from the spirit and scope of the present invention, when can be used for a variety of modifications and variations.Cause
