A microwave pulverized coal pyrolysis and carbonization furnace

Abstract

The invention discloses a microwave pulverized coal cracking and retorting furnace, which comprises a feeding hoist, a limit-sealed coal storage bunker and a limit-seal coal supply bunker, a furnace body (2) in a preheating drying section, and a ceramic plate turning machine (3). , heating section furnace body (4), pyrolysis and carbonization section furnace body (5), cooling section furnace body (6), discharge section furnace body (7), gas ascending channel (8), refractory heat preservation system (9), microwave System (10), microwave slit antenna (11), frame platform (12), semi-coke cooling system and gas water seal (13), semi-coke collection system (14), raw gas collection port (15), furnace body Microwave suppression and explosion-proof devices are installed at the joints of components. The present invention acts on the cracking and carbonization of pulverized coal based on the principle of microwave heating and non-thermal catalytic effect, so compared with the current dominant gas heat carrier carbonization process, it is suitable for a wide range of raw coal specifications, fast cracking speed, high output efficiency, good product quality, and no waste. Environmental pollution and other aspects have obvious advantages.

Description

technical field [0001] The invention relates to a dry distillation furnace, in particular to a microwave pulverized coal cracking dry distillation furnace. Background technique [0002] (1) The project is in line with the overall strategy of national economic development and promotes the rapid development of regional economy. The Eleventh Five-Year Plan of my country's national economic and social development points out that it supports the western region to "transform resource advantages into industrial advantages, vigorously develop characteristic industries, strengthen clean energy, and advantages Mineral resource development and processing". Based on the rich local coal resources, this project produces high-quality semi-coke (which can be used as metallurgical injection material and power plant injection coal), high-quality light component coal tar (which can be hydrogenated to produce diesel and gasoline), high calorific value Component coal gas (most of its components a...

AI Technical Summary

Problems solved by technology

Taking a thermal power enterprise that burns 1 million tons of low-grade coal annually as an example, if it adopts the method of direct combustion without upgrading and processing, it will save more than 50,000 tons of tar with a very high market value and a considerable amount of tar each year. Gas is a great waste of national strategic resources
