Abstract
The invention relates to new environmental protection cleanliness type coal and its preparation method. The coal can overcome the defect while burning and improve heat yield. And its constituent parts by weight are as follows: coal 675-775, magnesia 150-200, and magnesium chloride 75-125. It is multi purpose coal which can be used in industry and civil use etc.
Description
Technical field:
The present invention relates to a kind of environmental-protection clean briquette and preparation method thereof.
Background technology:
Existing burning of coal rate is lower, and the coke that the burning back produces is many, and it is not thorough to burn.And not environmental protection, damage ratio is more serious, and quantity of heat production is low.
Summary of the invention:
The purpose of this invention is to provide environmental-protection clean briquette of a kind of rate of combustion height, environmental protection and preparation method thereof.
Above-mentioned purpose realizes by following technical scheme:
A kind of environmental-protection clean briquette, its composition comprises: coal, magnesium oxide, magnesium chloride, the parts by weight of the coal in the described environmental-protection clean briquette are 675～775, and described magnesian parts by weight are 150～200, and the parts by weight of described magnesium chloride are 75～125.
Above-mentioned environmental-protection clean briquette, contain coal slime or coal drystone or carbide slag or coke end in the described environmental-protection clean briquette, described coal slime ratio of weight and number is 100～450, the coal drystone ratio of weight and number is 100～450, the carbide slag ratio of weight and number is 100～450, and the ratio of weight and number at coke end is 100～450.
The preparation method of above-mentioned environmental-protection clean briquette, the coal of getting above-mentioned parts by weight is put in the pulverizer and is pulverized, the powder of getting the coal after magnesium oxide, magnesium chloride and the pulverizing of above-mentioned parts by weight is then put into together in the three-dimensional stirrer and is stirred, back taking-up mixture stirs, at last the mixture that stirs is put into and carried out forming processes in the shaper, the coal type of the environmental-protection clean briquette after the moulding is coal briquette or honeycomb briquette, and the environmental-protection clean briquette after the moulding is placed and can be transported, preserves or advance the stove burning after 12 hours.
Above-mentioned environmental-protection clean briquette, add coal slime or coal drystone or carbide slag or coke end in the described mixture, described coal slime ratio of weight and number is 100～450, the coal drystone ratio of weight and number is 100～450, the carbide slag ratio of weight and number is 100～450, and the ratio of weight and number at coke end is 100～450.
This technical scheme has following beneficial effect:
1. this product, can be under the influence that is not subjected to ambient conditions (weather, temperature) ordinary production, existing moulded coal can only be produced in spring, summer, three seasons of autumn, and the product of producing under the low situation of temperature is not done, it is a lot of to become wet coal and broken phenomenon in indoor or the stove hall, and this product then need not dry or dry, and formed product is how advanced the stove burning after 12 hours, production efficiency can be carried out large quantities of mass production than higher.
2. the toxic gas that produces of this product burning back reduces 40～60% relatively, and capability of environmental protection and existing coal facies are than having improved greatly.
3. this product has owing to adopt the shape of coal briquette and honeycomb briquette, and good forming effect is difficult for broken and the burning of coal rate is improved, and the heat of generation also improves relatively.
This product in when burning because the area that the influence of its shape contacts with air is bigger, fully burning under the effect of oxygen in air, during the burning of this product is outside in to burn, slight crack appears in the moulded coal surface, ash after the burning is scattered in below the furnace wall once moving gently, can coking, so what can not resemble that in the past coal produces after burning is coke and block furnace bottom and make drawing badly of furnace bottom, thereby influenced the burning of coal rate.
In this product owing to add coal slime, coal drystone, carbide slag and coke end, their thermal value is equivalent to the thermal value of coal, but its cost is lower, so this product makes this production cost of products reduce on the basis of the thermal discharge that does not influence coal at the adding above-mentioned raw materials, and the saving energy, the economic benefit of bringing is very big.
6 products reach best combustion value and pressure intensity after one week, can bear very big pressure, automobile fills that carry to press not can be broken and can outdoor storage, very good aspect waterproof, place it in water mileage sky and add any pressure, do not intake in the not broken and body of product, taking out the back in the water can advance the stove burning as long as remove the moisture on surface, does not influence its effect.
7. this product required production site when producing is smaller, and price is identical with raw coal price on the market, and the profit of per ton product can reach 50～110 yuan, burns this product than the raw coal that burns and can save coal about 15～30%.
