The grate-cooler that collection pipeline is connected with breather valve.
In this patent cement kiln synergic processing waste liquid method be by waste liquid in pretreatment workshop through coarse filtration, fine straining, storage, all
Change, dispensing, mixing such as join at the technical process, are allowed to meet incineration disposal or part in cement rotary kiln and replace fuel；Its technique mistake
Journey is as follows:
1, waste liquid enters factory, discharging
Waste liquid divides two kinds of forms to be conveyed into factory.One is tank car transport, and another kind is the transport of ton bucket.According to different transport shapes
Formula, arranges two-way band snap joint flexible pipe discharge pipe.The waste liquid of above-mentioned two-way unloading is through filter 1 and filter 2 two grades
After filtration, it is transported to the interior storage of holding vessel 4 of correspondence, homogenizing according to waste liquid character delivery pump 3.
2, waste liquid stores homogenizing, dispensing mixing
The storage of waste liquid, homogenizing arrange four holding vessels 4(4A, 4B, 4C, 4D), every holding vessel 4 all uses low-level feeding, low level
Discharging is arranged.Each waste liquid tank 4 outlet connect a set of waste liquid induction system, this induction system successively by filter 5(5A, 5B,
5C, 5D), delivery pump 6(6A, 6B, 6C, 6D), the composition such as pipeline.Delivery pump 6 outlet conduit is respectively provided with two-way, and a road is certainly
Body waste liquid circulation homogenizing；One tunnel and other three holding vessels 4 according to proportion scale, by delivery pump 6 through effusion meter 7(7A, 7B,
7C, 7D) after metering conduit converges, enter pipe-line mixer 8(8A, 8B, 8C) mixing, after mixing waste liquid by booster pump 9(9A,
9B, 9C) enter spray gun 10(10A, 10B, 10C after pressurization) atomization, in spray gun 10 after machinery and compressed air double atomization
Drop is up to below 60um, and the waste liquid after atomization is spurted in kiln hood or kiln tail dore furnace.
3, waste liquid adds
3, two positions of waste liquid carry out speculating to add, and a position rotary kiln end arranges two toss area, kiln head cover toss area
With burner toss area, the toss area of kiln hood position is to be directly injected to gas flow temperature after waste liquid passes through spray gun 10A or 10B atomization
Being 1700 degrees Celsius, in temperature of charge is the rotary kiln of 1400-1600 DEG C, the time of staying, waste liquid was the highest at more than 10s
At a temperature of, moisture is evaporated, and organic components moment is decomposed, and the heavy metal of the inside participates in reaction and is cured to cement products.
Another location kiln tail dore furnace toss area, it is 800-900 that waste liquid is directly injected to temperature after being atomized by spray gun 10C
DEG C dore furnace in, the time of staying, at more than 4s, is more than 14s in the total system time of staying, and waste liquid moisture is evaporated, organic
Thing composition moment is decomposed, it is impossible to the composition of decomposition enters rotary kiln together with cement raw material, and heavy metal therein is cured to
Cement products.
Waste liquid typically at the stop 2s of 800 DEG C of temperatures above, is i.e. thoroughly decomposed.
4, gas sampling processes
Each holding vessel 4 top arranges breather valve 11(11A, 11B, 11C, 11D), exhalation waste gas is connected to workshop by pipeline and unloads
Material district, pump district Factory Building gas sampling pipeline, unification carries out harmless treatment in being transported to grate-cooler.
Beneficial effect
Waste liquid is added in rotary kiln end and kiln tail dore furnace after pretreatment, homogenizing, dispensing, mixing respectively, utilizes water
High temperature in mud production system, carries out harmlessness disposing by endangering composition in waste liquid, and process is continuous, automatic, safe and reliable, does not has
There is secondary pollution.High burning-value composition the most therein can be fully utilized, it is achieved waste liquid is innoxious, minimizing and resource
Change processes.
