Briquette binder and briquette manufacturing method

Abstract

The invention relates to a briquette binder and a briquette manufacturing method. Domestic animal blood or blood powder is compounded with organic wastewater containing natural polymers, using amount of the domestic animal blood is 7% to 15% of weight of coal, using amount of the blood powder is 10% of the weight of the coal, and using amount of the organic wastewater is 4% to 6% of the weight of the coal. The briquette binder and the briquette manufacturing method are characterized in that the domestic animal blood is performed anti-coagulation and antiseptic treatment, namely an anticoagulant occupying 0.48% to 2% of weight of the blood and an antiseptic occupying 0.4% to 0.6% of the weight of the blood are added.

Description

technical field [0001] The invention relates to a molded coal binder and a preparation method thereof, and also relates to the utilization of industrial organic waste water. Background technique [0002] The strength of briquettes depends greatly on the binder. At present, there are many kinds of briquette binders, but there are deficiencies in comprehensive evaluation. For example, the briquette coal with bituminous coal tar and heavy oil as binders is expensive, pollutes seriously, and consumes a lot of energy due to hot pressing. The disadvantages of coal briquettes that use clay as binder have low strength and large ash content, making it difficult to meet the needs of the industry in terms of calorific value or combustion performance; there are also artificially synthesized high molecular polymers used as briquette binders, but most of them It is difficult to use because of its high price; PVA is widely used as a coal briquette binder. Such as CN86101384 discloses a k...

Problems solved by technology

However, the addition of the above two binders in the briquette process is relatively high, the cost is relatively high, and the process is relatively complicated. Especially when PVA is used as the briquette binder, the selection of sulfur-fixing additives is relatively large. Experiments have proved that: When adding sulfur fixatives such as slaked lime or quicklime carbide slag, or adding alkaline substances, the strength of the briquette will decrease, so it cannot be directly compounded with alkaline organic wastewater as a briquette binder
