Description

A kind of clean rapid hardening formula slag treatment equipment

Technical field

The utility model relates to Industrial Solid Waste enhancement and treatment field, particularly relates to a kind of sensible heat, the clean rapid hardening formula slag treatment equipment that reduces dust pollution discharge that reclaim smelting.

Background technology

At present, the slag of domestic 98% adopts water quenching method to carry out being granulated and cooling, and every punching 1 ton of blast furnace slag produces the washing slag water of 0.8 ~ 1.2 ton of temperature about 85 DEG C.In the process, huge heat energy wastes, and also produces the harmful water steams such as a large amount of hydrogen sulfide, sulfurous gas, causes environmental thermal pollution.Dry granulation slag technology in positive research, belongs to one of steel industry important technical demand both at home and abroad.

Such as, Authorization Notice No. CN203846041 U, the patent No. be 201420138371.1 Chinese patent disclose a kind of multi-functional pelletizer, comprise storage slag chute, granulation unit, underframe, described underframe inner bottom surface is with a chute district and these both sides, chute district offer a water-in, a slag notch respectively, namely forming an airtight furnace chamber between device for cooling and chute district at underframe upper water safety dress and device for cooling, this furnace chamber periphery arranges cooling and waste heat recovery layer; Simultaneously; above described i.e. device for cooling, storage slag chute is set; center position at right angle setting granulation unit in the furnace chamber below i.e. device for cooling and arrange the axle protector of a Straight below this granulation unit and between underframe, described axle protector inside is installed transmission shaft and is provided with mandrel connector bottom this transmission shaft.This structure is conducive to the contradiction solving cooling and waste heat recovery rapidly; After can making cooling, clinker glass rate reaches more than 95%; Many places, multiple spot, repeatedly waste heat recovery can be realized.

But this case is it is important to note that said structure also exists the difficult problem cooled rapidly, and thus, this case, for above aspect, has been set up the structures such as note wind injector, thus carried out rational modification to prior art.

Utility model content

For above defect, the utility model provide one be conducive to realizing the cold and rapid hardening of slag speed, clinker glass rate high, sensible heat can be reclaimed, be conducive to falling oligosaprobic clean rapid hardening formula slag treatment equipment, to solve many deficiencies of prior art.

For achieving the above object, the utility model is by the following technical solutions:

A kind of clean rapid hardening formula slag treatment equipment, comprise pelletizer body and storage slag chute, described pelletizer bodies top installs pelletizer Cang Ding, and this pelletizer body periphery is fixed by support steel beam, and motor is housed this pelletizer body interior and its clutch end connects pelletizing disc by transmission shaft;

Described pelletizer bodies top central position fixedly mounts the storage slag chute of taper and is storing up the some note wind injectors of slag chute periphery distribution; each note wind injector be all arranged in pelletizer storehouse top upper surface and with pelletizer inner space; each note wind injector inlet mouth is equipped with Venturi, and each Venturi and place are noted the high-pressure feed water pipe that wind injector is arranged and be communicated with.

Correspondingly, described pelletizer body is cylindrical structure, and pelletizing disc is wave striated and at right angle setting;

Described storage slag chute bottom surface with immediately below pelletizing disc aligned in position.

The beneficial effect of clean rapid hardening formula slag treatment equipment described in the utility model is:

(1) by having set up the structures such as note wind injector, Venturi and high-pressure feed water pipe, solve the difficult problem cooled rapidly, while not affecting waste heat recovery effect, also remove the dust that slag collision produces, reach the good result of cleaner production;

(2) high, the quality better of clinker glass rate, pollution-free;

(3) sensible heat can be reclaimed, reduce and pollute, there is higher economic benefit and social benefit.

Accompanying drawing explanation

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the structural representation of clean rapid hardening formula slag treatment equipment described in the utility model embodiment.

In figure:

1, slag chute is stored up; 2, pelletizer Cang Ding; 3, pelletizing disc; 4, transmission shaft; 5, motor; 6, Venturi; 7, high-pressure feed water pipe; 8, wind injector is noted; 9, support steel beam; 10, pelletizer body.

Embodiment

As shown in Figure 1, clean rapid hardening formula slag treatment equipment described in the utility model embodiment, comprise pelletizer body 10 and storage slag chute 1, described pelletizer body 10 is cylindrical structure and top, pelletizer storehouse 2 is installed at its top, this pelletizer body 10 periphery is fixed by support steel beam 9, motor 5 is not housed in this pelletizer body 10 inside and its clutch end connects the pelletizing disc 3 of vertically arranged wave striated by transmission shaft 4, thus by motor 5 transmission pelletizing disc 3;

Correspondingly; described pelletizer body 10 top center fixedly mounts the storage slag chute 1 of taper and the note wind injector 8 of some tubulars that distributes in storage slag chute 1 periphery; storage slag chute 1 bottom surface wherein with immediately below pelletizing disc 3 aligned in position; each note wind injector 8 wherein be all arranged in pelletizer storehouse push up 1 upper surface and with pelletizer inner space, Venturi 6 is housed each note wind injector 8 inlet mouth and each Venturi 6 and place are noted high-pressure feed water pipe 7 corresponding on wind injector 8 and be communicated with.

Clean rapid hardening formula slag treatment equipment described in above the utility model embodiment, liquid slag is injected in pelletizing disc body by storage slag chute, and liquid slag, with the rotating speed of 2600 turns per hour, due to the effect of centrifugal force, is thrown to surrounding by pelletizing disc.The note wind jet apparatus at top adopts venturi principle design; the water smoke utilizing multiple high pressure spray nozzle to spray flow velocity higher is kinetic force; the vacuum produced; a large amount of freezing airs and vaporific water coolant is injected to pelletizer inside; merge with high-temperature liquid furnace slag, make liquid slag rapidly cooling solidification and crystallization within 3 second time, define quality higher, glass rate reach more than 95% high-quality slag; at this moment slag temperature is reduced to about 600 DEG C, enters waste heat recovery link.

The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
