Abstract
The invention provides a synthetic ammonia gas-producing briquette, which is prepared from the following compositions by weight portion: 85 to 90 portions of pulverized anthracite and 10 to 15 portions of organic compound binder; and the organic compound binder is prepared from straws, humic acid and NaOH solution in a weight ratio of 2.5-5.5:6.5-15.5:82.0-88.0. The synthetic ammonia gas-producing briquette has wide raw material sources, low production cost, high activity and cold and heat intensity, reduces the burning point and smoke dust discharge amount due to addition of biomass, improves the burn-off rate and reduces the coal consumption of a ton of ammonia.
Description
Technical field
The present invention relates to moulded coal, specifically belong to a kind of synthesis ammonia gas preparation molded coal and preparation method thereof.
Background technology
The ammonia operation with coal based on the high-quality anthracite block coal because the anthracite block coal shortage of resources, on the high side.The at present feed coals that adopt moulded coal to do the ammonia operation of fertilizer plant more.Additive adopts sodium humate solution mostly, is pressed into coal briquette or coal rod through height again with pulverized anthracite mix, the system that stirs, macerates, and the oven dry fed to boiler uses.
The moulded coal shortcoming that above method is made is: degree of compactness height, active low, carbon residue rate height, ton ammonia coal consumption rate height.Thereby influence gas forming amount, improved production cost.
Technology contents
The object of the present invention is to provide a kind of active high, cost is low, the synthesis ammonia gas preparation molded coal of energy-conserving and environment-protective and preparation method thereof.
A kind of synthesis ammonia gas preparation molded coal provided by the invention, Ji following component is made by weight: pulverized anthracite 85-90, organic compound binder 10-15; Described organic compound binder be by stalk, humic acids and NaOH solution by weight 2.5-5.5: 6.5-15.5: 82.0-88.0 makes.
The preparation method of a kind of synthesis ammonia gas preparation molded coal provided by the invention comprises the steps:
(1) with the stalk natural air drying, cutting rolls to 2-3 centimetre, and pulverized anthracite is broken to below 3 millimeters;
(2) get the NaOH solution that stalk, humic acids and concentration are 1.5%-3.0% by weight 2.5-5.5: 6.5-15.5: 82.0-88.0, in reactor, add NaOH solution earlier, add stalk again, stir, heat up, when temperature rises to 90 ℃～95 ℃, add humic acids, react 40-60min down at 90 ℃～95 ℃ and make organic compound binder;
(3) in proportion organic compound binder is mixed with pulverized anthracite, stir, moulding, oven dry obtains highly active gas-making type coal product.
Compared with prior art, the invention has the advantages that:
The present invention makes organic compound binder through the NaOH solution modification simultaneously with biomass straw (corn or wheat stalk) and humic acids, can bring into play the advantage of biomass straw and Sodium salts humic acids simultaneously, produces highly active gas-making type coal.In the adhesive preparation process, biomass straw is processed into the strip of 2～3cm and through the NaOH solution modification, in moulded coal, can play the connection effect, improve moulded coal ultimate compression strength, the cavity that forms behind the biological matter straw burning in the moulded coal combustion processes can be beneficial to entering of oxygen, improved-type coal combustion effect promotes moulded coal perfect combustion more; Sodium salts humic acids with humic acids modification generation, it is a kind of water miscible binding agent, coal had very strong avidity, can wetting well coal grain surface, and infiltrate in the microvoid structure of coal, help to improve the moulded coal cold strength, Sodium salts humic acids also has the effect as sulphur capturing catalyst in the moulded coal combustion processes simultaneously.
In a word, the organic compound binder raw material that adopts among the present invention is cheap and easy to get, and production cost is low, not only can significantly improve the moulded coal reactive behavior, and moulded coal has hot and cold intensity height, the voidage height, and burning-point is low, gas forming amount height, characteristics such as the carbon residue rate is low.
