Pressure gasified, water-repellent, drying free agent for bonding coal in gasified industry type

Abstract

This invention discloses a binding material for producing industrial waterproof briquette capable of being pressurization-gasified without drying process. The binding material is powdery, and is formed by: pulverizing Sorel cement 50%, bentonite 15%, steel slag 20%, and graphite tailing 10%, and trisodium phosphate 5%, and mixing. The briquette produced from the binding material has such advantages as high cold strength, good waterproof property, convenient transportation, low cost, simple process, convenient maintenance, high thermal stability, high gasification rate, and good sulfur-fixation effect. The binding material can solve the problems of low waterproof capacity, low gasification rate, low combustion efficiency, low thermal strength and no air permeability faced by conventional briquette.

Description

Technical field [0001] The invention is a waterproof and natural drying binder for continuous gas generation in gasification industrial briquettes in a gas generator, and for stacking briquettes in the open air. Background technique [0002] At present, there are many defects in the gasification industrial briquettes currently produced in China, such as the briquettes are not waterproof, need to be dried, the cost is high, the cold and heat intensity is low, the gasification effect is not good, there are black hearts, the reducibility is poor, and the gasification rate is low , high oxygen content, low carbon monoxide production, and low calorific value of gas. Not suitable for mass production and cannot be transported over long distances. The need to add packaging also has the problem of high cost, and the price of the binder is high, which is harmful to the human body and the environment due to resource constraints. Contents of the invention [0003] In order to overco...
