Description
Technical field
The present invention relates to corn deep processing fields, and the method for burning corn pulp is mixed in particular to a kind of coal.
Background technique
Sulfurous acid soaking corn is that the first step and wet-milling in corn wet milling production basic process extract the primary of starch
Process not only breaks up protein net in albuminous cell, separates starch and non-starch part, can also impregnate in niblet out
Solable matter, inhibit corn in microorganism nocuousness activity, softening corn reduce mechanical strength convenient for postorder process, immersion
Sulfurous acid afterwards forms dilute corn pulp, forms corn pulp after evaporation and concentration.
The corn pulp dry matter content formed after concentration is about 40%, to the main methods of corn pulp be to maize peel into
Row whitewashing processing, sewage treatment etc., but whitewashing processing easily affects to fiber color, chemical oxygen demand in corn pulp
(COD) height is measured, sewage treatment can be affected greatly, therefore the two and nonideal processing method.
Summary of the invention
The purpose of the present invention is to solve the problem that corn pulp processing in corn deep processing industry is difficult, the present invention is provided
A kind of method that coal mixes burning corn pulp.
To achieve the above object, the technical solution adopted by the present invention is as follows:
A kind of method that coal mixes burning corn pulp, method particularly includes: the corn pulp generated after being concentrated by evaporation with corn steep liquor
For raw material, corn pulp is sent into boiler system, mixes burning after the atomization of the combustion gun of boiler emulsion zone two sides, the corn pulp
Mixing burning amount is greater than 0 and to be less than or equal to 6 m3/h。
Further, the solid content of the corn pulp is 38%~42%.
Further, the burner hearth bed temperature of the boiler system maintains 850 ~ 950 DEG C.
Further, when burning, the excess air coefficient in boiler is controlled 1.21.
Further, the nozzle of the combustion gun sprays corn pulp in spraying form, and the pressure of corn pulp is 4bar,
Air pressure is 4bar.
Further, the low heat valve of corn pulp is 1453 kcal/kg, 3190 kcal/kg of low heat valve of coal.
The beneficial effect of the present invention compared with the existing technology is:
It tests and measures 3190 kcal/kg of coal low heat valve, and 1453 kcal/kg of corn pulp low heat valve, by corn pulp
It is sent into Boiler Mixed Burning with coal, not only can achieve the purpose of processing corn pulp, while fire coal can be saved, and nitrogen oxidation in flue gas
Object content is substantially reduced.
The method for burning corn pulp is mixed this invention describes a kind of coal, in the case where coal and constant boiler load, consumes coal
Amount with do not come into operation corn pulp when compared with, instantaneous coal feeding amount reduces by 2 ~ 3 t/h, simultaneously because corn pulp comes into operation, in boiler smoke
Nitrogen oxides be substantially reduced and lower than 100 mg/ m3, reach national emission standard, therefore can be by Denitration in Boiler system
It releases, reduces the urea liquid consumption of 40 ~ 70 kg/h, desalination water consumption can reduce by 120 ~ 210kg/h.
This method mixes burning corn pulp power generation by coal and solves the problems, such as that corn pulp processing is difficult, and corn is efficiently utilized
The energy of slurry, reaches energy-saving and emission-reduction, the purpose improved environmental sanitation.
