Abstract
The present invention relates to top burning type coal which is composed of disintegrated raw coal, faulty coal (weathered coal, gangue and slag not thoroughly burned), sodium laurylsulfate, urotropine, washing powder, slaked lime Ca(OH)2 and paper-making waste liquid through alkaline processes. The manufacture method comprises the steps that the disintegrated raw coal and the faulty coal are disintegrated and magnetically selected, and iron is removed from the disintegrated coal and the faulty coal; the sodium laurylsulfate and the urotropine are respectively prepared into solution, and then all the substances are added with a proper amount of water and uniformly mixed; the substances are pressed into honeycomb coal and dried. The present invention can obviously reduce smoke dust and sulfur dioxide which are produced after the coal is burned, and is favorable to environmental protection. The top burning type coal of the present invention is suitable for domestic burners.
Description
One, technical field
The present invention relates to a kind of moulded coal, be specifically related to a kind of upper ignition coal briquette.
Two, background technology
Directly discharging behind the raw coal combustion is a major reason that causes topsoil, and bituminous coal is particularly arranged.At present, domestic burners does not generally all have cleaning apparatus, the directly burning raw coal that adopt more, and directly discharging works the mischief to environment.Briquette production is used the history that has had for many years, and for example, common honeycomb briquette is generally made moulding by hard coal, uses for domestic burners.The advantage of moulded coal is the broken smalls that is unfavorable for the domestic burners use can be made bulk, is convenient for people to use, and avoids broken smalls waste.Moulded coal can reduce the flue dust that the burning back produces, and still, this minimizing is limited.On the other hand, low grade coal such as the weathered coal in colliery, coal gangue and the big Industrial Boiler unburnt slag of discharging never has way and makes full use of.
Three, summary of the invention
The purpose of this invention is to provide a kind of upper ignition coal briquette, can use coal as raw material inferior, can significantly reduce the burning back and produce flue dust and sulfurous gas, bituminous coal can be used as hard coal and burn.
Upper ignition coal briquette of the present invention is to make by following step:
The first step: choose following materials by weight
Broken powder raw coal 500kg
The slag 500kg of weathered coal, coal gangue or last after-flame
Sodium lauryl sulphate 0.5--2kg
Wu Luotuo 1--3kg
Washing powder 1--2kg
Sulfide lime Ca (OH)
250--80kg
Waste liquor in alkaline process paper making 150-200kg
Second step: after broken powder raw coal is crushed to granularity about 16 orders, carry out magnetic separation, remove irony, make former coal dust, the slag of weathered coal, coal gangue or last after-flame is carried out magnetic separation earlier, remove irony, be crushed to the granularity about 16 orders then, make coal dust inferior, with sodium lauryl sulphate and urotropine, be mixed with solution respectively
The 3rd step: with above-mentioned former coal dust, above-mentioned coal dust inferior, above-mentioned sodium dodecyl sulfate solution and above-mentioned urotropine solution and washing powder, sulfide lime Ca (OH)
2, waste liquor in alkaline process paper making mixes, and adds an amount of water and stirs, its humidity reaches: the usefulness pressure extrusion is plastic, falls the degree that can scatter on the ground,
The 4th step: the above-mentioned mixture that is mixed is struck out cellular moulded coal with molding coal machine, dry.
Using method: cellular moulded coal eyelet of the present invention is piled up in the stove hall relatively, from top it is ignited, flame transmits downwards from the eyelet of cellular moulded coal and the top layer at edge, ignite up to moulded coal the bottom, wind enters from stove hall bottom, the moulded coal elder generation after-flame of bottom during stoking, is replaced the moulded coal of bottom.
Combustion principle: sodium lauryl sulphate, urotropine and washing powder play respectively and help oxygen, combustion-supporting, expansible effect in the present invention's prescription, help burning, although be mixed with low grade coal, also can all burnout.After fire was lighted from top, rapid combustion was to the bottom, and the obnoxious flavour that is produced process from the naked light obtains secondary combustion, has reduced discharging; Sulfide lime Ca (OH)
2Play the effect of sulphur-fixing agent, in high temperature,, form dehydrated gyp-, reduced the quantity discharged of sulfurous gas with the sulfurous gas reaction; Waste liquor in alkaline process paper making plays the effect of caking agent in the pasty state, can reduce dust discharge.Above-mentioned each material acting in conjunction makes discharging cigarette, dirt and sulfurous gas all be lower than national standard.
Advantage of the present invention is: can utilize low grade coal, can significantly reduce the burning back and produce flue dust and sulfurous gas, help environmental protection.
Four, embodiment
Upper ignition coal briquette of the present invention is to make by following step:
The first step: choose following materials by weight
Broken powder raw coal 500kg
The slag 500kg of weathered coal, coal gangue or last after-flame
Sodium lauryl sulphate 1kg
Urotropine 2kg
Washing powder 1.5kg
Sulfide lime Ca (OH)
270kg
Waste liquor in alkaline process paper making 170kg
Second step: after broken powder raw coal is crushed to granularity about 16 orders, carry out magnetic separation, remove irony, make former coal dust, the slag of weathered coal, coal gangue or last after-flame is carried out magnetic separation earlier, remove irony, be crushed to the granularity about 16 orders then, make coal dust inferior, with sodium lauryl sulphate and urotropine, be mixed with solution respectively
The 3rd step: with above-mentioned former coal dust, above-mentioned coal dust inferior, above-mentioned sodium dodecyl sulfate solution and above-mentioned urotropine solution and washing powder, sulfide lime Ca (OH)
2, waste liquor in alkaline process paper making mixes, and adds an amount of water and stirs, its humidity reaches: the usefulness pressure extrusion is plastic, falls the degree that can scatter on the ground,
The 4th step: the above-mentioned mixture that is mixed is struck out cellular moulded coal with molding coal machine, dry.
In the present invention's batching, also can not add low grade coal, all make major ingredient, can obtain higher calorific value with raw coal.
