Description
Technical field
The utility model relates generally to field of smelting, is specifically related to a kind of blast furnace slag bath waste heat recycling system.
Background technology
In recent years, China's smelting iron and steel industry development is rapid, blast furnace ironmaking has become the Main Means of most of iron work, blast furnace ironmaking is when coming out of the stove, have scum to produce, because the temperature of scum is quite high, need to enter in slag bath and pass through water cooling, blast furnace slag quenching water is a kind of byproduct that blast furnace ironmaking produces, the temperature of washing slag water is very high, again because slag can make water produce violent water vapour when entering slag bath, make a large amount of vapor barrier sight lines, more with dense peculiar smell, these steam contain a large amount of heats simultaneously, can only be wasted in the middle of air, because temperature is too high during flushing cinder, easily cause splashing, there is potential safety hazard.
Summary of the invention
For problem existing in prior art, a kind of blast furnace slag bath waste heat recycling system that the utility model provides, the safe retrieving that can realize blast furnace slag quenching water waste heat utilizes.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of blast furnace slag bath waste heat recycling system, mainly comprises collecting hood, dragveyer, blower fan, heat-exchange system, chimney, slag bath; Described collecting hood inside is provided with slag bath, is set to ramped shaped bottom described slag bath, and described collecting hood sidewall is provided with slag inlet, by slag inlet to slag input in slag bath; Described slag bath inside is provided with dragveyer, and dragveyer one end is stretched into bottom slag bath, and the other end stretches out slag bath; Another sidewall of described collecting hood is provided with slag notch, and by slag notch, dragveyer is connected to torage tank; The slag of slag bath inside is pulled out by described dragveyer, is transported in the torage tank outside collecting hood; Described collecting hood top is provided with pipeline, is connected with blower fan by pipeline, and the high-temperature steam in blower fan collecting hood is taken away; Described blower fan is connected with heat-exchange system, is fallen by the waste heat recovery of heat-exchange system by high-temperature gas; Described heat-exchange system outlet is connected with blower fan, and be connected with chimney by blower fan, the gas after heat exchange is gone out through smoke stack emission by blower fan.
Preferably, described collecting hood is set to and entirely shrouds formula, can finish the work by peripheral operation, eliminates work personnel and enters, protect personnel safety, effectively have collected high-temperature flue gas.
The utility model compared with prior art beneficial effect shows: by the effect of collecting hood; the waste heat of washing slag water is recycled efficiently; the collecting hood simultaneously entirely shrouding formula prevents the diffusion of high-temperature steam; effectively improve environment; simultaneously staff gets final product complete operation outside, the available protecting safety of work personnel.
