Cracking quality-separation utilization production system of briquette prepared from coal with small particle size

Abstract

The invention provides a cracking quality-separation utilization production system of briquette prepared from coal with a small particle size. The cracking quality-separation utilization production system of briquette prepared from coal with a small particle size is characterized in that the system includes a rotary furnace, a gas purification device, a coal cracking product mixing device, a briquette production device and a conveying device, and cracked products in the rotary furnace are conveyed to the gas purification device and the coal cracking product mixing device. The cracking quality-separation utilization production system of briquette prepared from coal with a small particle size provided by the invention can greatly increase the contact area between gas and a desulfurizer, improves the desulfurization efficiency and the quality of purification, makes the effect of mixing better, has the advantages of energy saving, environmental protection and energy conservation, can detect the pressure of the gas, make the mixing of tar more fully through multiple mixing treatment, can improve the quality of products, is more environmentally friendly and energy-saving, has the advantages of green cycle, improves the quality of the products, reduces the cost, and improves the economic benefit.

Description

technical field [0001] The invention relates to the field of coal cracking, in particular to a production system for cracking, quality-separating, and utilization of small-diameter coal to prepare briquettes. Background technique [0002] my country is rich in coal resources, and most of the raw coal is used for direct combustion except for coking and conversion processing. The direct combustion of coal leads to the fact that the oil and gas resources rich in coal have not been fully refined and utilized, and the thermal efficiency of direct combustion is low, which seriously damages the environment. Coal pyrolysis process can be divided into two types: external heat type and internal heat type. The thermal efficiency of the external heat type is low, and the secondary decomposition of volatile products is serious; the internal heat type process overcomes the shortcomings of the external heat type, and transfers heat to the coal with the help of heat carriers (solid heat ca...
