Description

A kind of coal saving and combustion supporting sulfur fixer and preparation method thereof
Technical field
The present invention relates to a kind of coal saving and combustion supporting sulfur fixer and preparation method thereof.
Background technology
At present, the main fuel that is used for industry or civil boiler and kiln is a coal, but owing to contain a large amount of sulphur compositions in the coal, thereby in coal combustion process, produce a large amount of sulfurous gas and flue dust, caused great environmental pollution.In coal production and washing process, produced a large amount of coal gangues, coal slime, wash in low calorific value coal resource such as coal; China is annual to produce the coal gangue, the coal slime that can be used for generating electricity, wash in low calorific value coal resource such as coal more than 300,000,000 tons; Accelerate development the low calorific value coal power generating industry; To realizing that the low calorific value coal resource efficiently transforms nearby; It is significant to improve the coal resources utilising efficiency; A large amount of coal gangues, coal slime, wash in low calorific value coal such as coal pollute because of its burning produces many, thermo-efficiency is low is abandoned, existing fire coal combustion-supporting desulfurizer can not improve the combustion-supporting effect and the captured sulfur result of low calorific value coal simultaneously, to solve air pollution problems inherent and the thermo-efficiency problem of fire coal in the coal-fired process.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, first purpose of the present invention is to provide a kind of coal saving and combustion supporting sulfur fixer, adds this agent to coal gangue, coal slime, in washing in the low calorific value coal such as coal, can improve the combustion-supporting effect and the captured sulfur result of low calorific value coal simultaneously.
This coal saving and combustion supporting sulfur fixer, form by weight ratio by following compositions:
Sodium-chlor 23-36 part, quicklime 16-24 part, potassium permanganate 3-8 part, VAL-DROP 4-6 part, potassium perchlorate 0.3-0.7 part, SODIUMNITRATE 8-12 part, yellow soda ash 3-8 part, red stone 3-7 part, silicon-dioxide 0.4-0.6 part.
As better proportioning, this coal saving and combustion supporting sulfur fixer is made up of following compositions by weight ratio:
Sodium-chlor 28-32 part, quicklime 19-21 part, potassium permanganate 4-6 part, 5 parts in VAL-DROP, potassium perchlorate 0.4-0.6 part, SODIUMNITRATE 9-11 part, yellow soda ash 4-6 part, red stone 4-6 part, silicon-dioxide 0.4-0.6 part.
As a kind of proportioning of the best, this coal saving and combustion supporting sulfur fixer is made up of following compositions by weight ratio:
30 parts in sodium-chlor, 20 parts in quicklime, 5 parts in potassium permanganate, 5 parts in VAL-DROP, 0.5 part of potassium perchlorate, 10 parts in SODIUMNITRATE, 5 parts in yellow soda ash, 5 parts of red stone, 0.5 part of silicon-dioxide.
Add the combustion-supporting sulfur-fixing agent that said ratio constitutes in the low calorific value coal such as coal to coal gangue, coal slime, in washing after; Red stone under the effect of quicklime and silicon-dioxide, has formed calcium-iron-sulphur-silicon-oxygen system as catalyzer in the fired coal combustion process; Thereby form heat-resisting silicate stable phase; Cover or the parcel calcium sulphate crystal, stoped calcium sulfate at high temperature to decompose, strengthened the captured sulfur result of this agent; Wherein sodium-chlor, yellow soda ash are as raising agent; Potassium permanganate, VAL-DROP, potassium perchlorate and SODIUMNITRATE are as strong oxidizer; Can oxygenation in fire coal, catalyticcombustion, thereby play combustion-supporting effect, and the interpolation of raising agent makes fire coal more bulk; Be convenient to the burning successively after the oxygenation, improved coal-fired thermo-efficiency.
In sum, adopt this combustion-supporting sulfur-fixing agent after, can improve the combustion-supporting effect and the captured sulfur result of low calorific value coal simultaneously, thereby solve air pollution problems inherent in the coal-fired process and coal-fired thermo-efficiency problem.
Can adopt following method to prepare this agent: the silicon-dioxide thorough mixing of the red stone of the yellow soda ash of the SODIUMNITRATE of the potassium perchlorate of the VAL-DROP of the potassium permanganate of the quicklime of the sodium-chlor of 23-36 part, 16-24 part, 3-8 part, 4-6 part, 0.3-0.7 part, 8-12 part, 3-8 part, 3-7 part and 0.4-0.6 part and the water that adds 3-5 part are stirred; Be ground into 20-60 purpose powder through kibbler again; At last with the powder behind the flour through bagger be packaged into the bag for use; The effect of adding water is that the said ratio component is mixed, and is beneficial to evenly and pulverizes.
With above-mentioned bag sprills by weight the ratio of 1%-3%:1 put into coal gangue, coal slime, wash in the low calorific value coal such as coal, stir, said mixture is used for cement kiln, makes the thermo-efficiency value that coal briquette for civillan use or Industrial Boiler can improve low calorific value coal; The 8%-16% that economizes on coal, discharging such as sulfurous gas, oxynitrides reduces 40%-60%, and can reduce boiler coke or noncoking; Remove the black dirt after boiler is heated; Heat exchange is quickened in loose coal seam, prolonged boiler work-ing life.
Above-mentioned bag sprills are put in the coal gangue by weight the ratio of 1%:1; Be fed in No. 1 circular fluid bed and use; Its contrast experiment's data (are being set under the same ambient conditionss such as fire box temperature, air output and air inducing amount as follows; Wherein the first six sky does not drop into this agent, drops into this agent in back six days):
1. the first six day, always go up 1012.9 tons of coal amounts, 5557.9 tons of steam productions are gone into the average thermal value 4708.36 card/grams of stove coal; 975.9 tons of coal amounts are always gone up in back six days, and 5405 tons of steam productions are gone into the average thermal value 4290.97 card/grams of stove coal,
Figure 691860DEST_PATH_IMAGE001
Ature of coal and a ton coal steam production were converted into the mark coal and carry out front and back and contrast and draw before and after coal saving and combustion supporting sulfur fixer added:
Reduction formula=total steam production/(going into the total coal consumption of the average thermal value/7000* of stove coal);
Before product adds: 5557.90/ (4708.36/7000*1012.90)=8.158 ton;
Product adds the back: 5405/ (4290.97/7000*975.9)=9.035 ton;
Signature coal steam production before the coal saving rate reduction formula=(product adds back signature coal steam production-product and adds preceding signature coal steam production)/product adds,
(9.035-8.158)/8.158=10.75%
After using this agent, coal saving rate is 10.75%.
2. use this coal saving and combustion supporting sulfur fixer also to have significant sulphur emission reduction effect admittedly.According to our effect analysis after circulating fluidized bed uses this agent, reduce SO2, NOx quantity discharged about 50%; Reduce smoke discharge amount about 40%.
