Abstract
The invention relates to a colored metallurgical industrial furnace decoking technology method which is characterized in that: the method comprises the following steps: 1. chemicals spraying points are distributed: a. four chemicals spraying points are distributed at the top part of the inner wall of the furnace body and at the position that the tail part of the furnace body is 3-5m far away from the flue combination part; 2. chemicals are sprayed at regular time: decoking agents are sprayed in the furnace and the flue by compression air through six chemicals spraying points, 3-6 times are carried out each day, and spraying is carried out at intervals of 4-8 hours, and 15-30min are used each time; 3. decoking: compression air is used for blowing loosened coke pieces in the furnace and the flue, so as to lead the coke pieces to fall off to a refuse vessel for removal every 3-5 days; the colored metallurgical industrial furnace decoking technology method solves the problems that the existing decoking technology lags behind, the removal effect is poor, and removal work is carried out by shutting down the furnace, the metallurgical furnace operation rate is affected, the working condition is poor and the cost is high, and is particularly suitable removal and maintenance of the colored metallurgical furnace flues.
Description
(1) technical field:
The present invention relates to metallurgical industrial furnace flue slagging scorification clearance technique, particularly a kind of colored metallurgical industrial furnace decoking technology method.
(2) background technology:
In heavy coloured pyrometallurgy production process, with a large amount of molten flue dust, these flue dust are after getting into flue usually for high-temperature flue gas; Along with reducing, temperature is bonded in walling of flue; Reduce the flue breathing area, influence the flue gas proper flow, cause the metallurgical furnace voltage rise high; What harm was produced normally carries out, for addressing this problem the following method of common employing: 1. increase the mechanical vibrator device on the walling of flue; 2. all kinds deashing device is installed, like ultrasonic wave deashing, high steam deashing etc. on the flue; 3. the artificial deashing of blowing out contains the explosion cleaning.There is shortcoming in said method: 1. mechanical vibrator ash removal method weak effect, and applicable surface is narrow, and the harm device security, reduces flue shelf life; 2. various soot blowers are better for the granular material effect, but for the stronger coking of caking property, remove weak effect; 3. blowing out is artificial removes, and influence the metallurgical furnace operating rate, and working condition is poor, and cost is high.
(3) summary of the invention:
It is backward in technique that the object of the invention will solve above-mentioned existing flue coke cleaning exactly, removes weak effect, needs blowing out to remove, and influences the metallurgical furnace operating rate, and working condition is poor, and problems such as cost height provide a kind of brand-new colored metallurgical industrial furnace decoking technology method.
Design principle of the present invention is: adopts the combination of chemical method and physical method,, changes the slagging scorification structure, let slagging scorification become loose through the little chemical substances of at first in flue gas, jetting, and auxilliary again simple physics method, thus thoroughly remove slagging scorification.
Concrete scheme of the present invention is: a kind of colored metallurgical industrial furnace decoking technology method; It is characterized in that: may further comprise the steps: 1. the spray snack made with traditional Chinese medicines is arranged: a. at the body of heater afterbody apart from 3-5m place, flue joint portion; And being positioned at the inboard wall of furnace body top layout has four spray snack made with traditional Chinese medicines, and b. respectively arranges a spray snack made with traditional Chinese medicines on the observation door of flue both sides; 2. regularly spray medicine: adopt compressed air in stove, to reach flue through above-mentioned six spray snack made with traditional Chinese medicines and spray into coke cleaning agent, every day 3-6 time, 4-8 hour once, each 15-30 minute; 3. coke cleaning: every 3-5 days, adopt the coke button that pneumatics wind is aimed in the stove and flue is loose to purge, coke button is come off and fall to dirt-excluding bucket and get rid of.
Four of the top of inboard wall of furnace body described in the present invention spray snack made with traditional Chinese medicines are for side by side or the circular arc arranged; Two spray snack made with traditional Chinese medicines are at a distance of the separation of 2-2.5m wherein; Two of both sides spray snack made with traditional Chinese medicines arrange at a distance of 1-1.5m with the body of heater two side, and four spray snack made with traditional Chinese medicines and furnace roof be the 200-300mm layout apart.
The dose that regularly sprays medicine among the present invention is designed to: two each 10-20kg of spray snack made with traditional Chinese medicines of inboard wall of furnace body crown center, all the other four the each 5-10kg of spray snack made with traditional Chinese medicines.
The present invention compares with traditional clinker removal method and has the following advantages:
1. can reduce the furnace outage time that causes because of the flue coking significantly, improve equipment operation rate, and reduce cause therefrom stop, the blow-on expense;
2. simple to operate, operating environment is good, and labour intensity reduces greatly;
3. slag cleaning is thorough, and flue is easy to maintenance, can prolong flue service life;
4. can better improve the waste heat boiler heat-transfer effect, energy consumption is low;
5. small investment, cost is low.
