Abstract
The stoving-free smoke-eliminating and sulfur-fixing briquet for boiler consists of bituminite as main component as well as ferric oxide, magnesium oxide, potassium sulfate, sodium hydroxide, sodium nitrate, aluminium sulfate, magnesium chloride and water. It needs no stoving and thus has less investment in equipment. It has both hot and cold strength, and high smoke-eliminating and sulfur-fixing effect.
Description
One, technical field:
The invention belongs to a kind of moulded coal, be specifically related to a kind of stoving-free smoke-eliminating sulfur-fixing briquet for boiler.
Two, background technology:
Existing briquette production mostly adopts organism liquid adhesive and coal dust mixing aftershaping, and moulding is after briquette prod is made in special drying plant oven dry.The moulded coal that existing stoving process is produced, facility investment is big, will consume a considerable amount of bunker coals during oven dry, and self-pollution is serious, and the hot strength of finished product is low, the used binding agent expense of ton moulded coal height, in combustion processes, cause the dust amount of carrying increase in the flue gas owing to moulded coal is defeated and dispersed.Do not reach environmental protection standard during burning.
Three, summary of the invention:
The technical problem that the present invention solves provides a kind of stoving-free smoke-eliminating sulfur-fixing briquet for boiler.
The technical solution used in the present invention is: for achieving the above object, taked to use the bonding of full-inorganic thing as moulded coal, sulphur-fixing agent, smoke suppressor in the present invention.Coal is that bituminous coal is raw material, manufactures stoving-free smoke-eliminating sulfur-fixing briquet for boiler.The bonding sulphur-fixing agent is the oxide compound of magnesium, the vitriol of potassium, sodium hydroxide, the vitriol of aluminium, the muriate of magnesium; Smoke suppressor is the oxide compound of iron, the nitrate of sodium or nitre soil.Its component and weight content are as follows: 100 parts in bituminous coal; Oxide compound 0.3-0.5 part of iron; Oxide compound 4-5.8 part of magnesium; Vitriol 0.2-0.3 part of potassium; Sodium hydroxide 0.01-0.012 part; The nitrate of sodium or nitre soil 0.24-0.48 part; Vitriol 0.23-0.35 part of aluminium; Muriate 2-2.8 part of magnesium; Total Water 10-12 part.
The present invention has adopted technique scheme, therefore compares with background technology, has the following advantages: need not dry, than the facility investment reduction 50-60% of stoving process.Cold strength＞500N/, hot strength＞300N/, the immersion several months is not loose.But temperature ordinary production below-20 ℃.Used binding agent expense is low, easy firing, and percentage of damage＜4% is transported in grey melting point＞1250 ℃, and smoke effect can reach 70-90%, and sulfur-fixing rate can reach 50-60%.So the present invention is referred to as stoving-free smoke-eliminating sulfur-fixing briquet for boiler.
Four, embodiment:
The present invention implements to go into operation in Liulin County He Chang moulded coal factory, and the test of this product Shanxi Province's environmental monitoring center meets environmental protection standard, and its prescription is as follows, and bituminous coal weight is 100 parts of meters, and the various deals of additive are as follows: 0.4 part of the oxide compound of iron; 5 parts of the oxide compounds of magnesium; 0.25 part in the vitriol of potassium; 0.01 part in sodium hydroxide; 0.4 part in the nitrate of sodium; 0.29 part in the vitriol of aluminium; 2.5 parts of the muriates of magnesium; 12 parts of Total Waters.
