Vertical automatic cokery with cold loading and cold discharge

Abstract

This invention is a kind of new-type vertical continuous coke oven, and a high-temperature dry distillation coking device of coal. The main characteristic of this invention is: After the cool furnace roof holds the coal, are urged to fall by the jar of hydraulic pressure of the furnt device, arrange the burnt device, list while being cool by stove bottom finally, dry distillation coal gas a part that course produce melt down and heat, the others support downstream production need; Air after preheating by heat exchanger, is it set up by oblique way fire dish mix burning with coal gas to enter, the high-temperautre waste gas after burning is discharged by the horizontal passway of the waste gas in the top of combustion chamber, retrieve heat energy for the power plant of remaining energy.

Description

technical field [0001] The invention relates to a vertical continuous coking oven, which belongs to a coal high-temperature dry distillation coking device. Background technique [0002] The furnace type of the conventional coking process is mainly a horizontal chamber coke oven for batch production. This type of furnace was established in the middle of the 19th century. Great progress has been made. However, due to its inherent intermittent operation mode, there are still disadvantages of causing serious pollution to the environment. In the coking production process, this type of furnace must frequently open the furnace door, coal charging, coke discharge, coke quenching and other production operations at high temperature, resulting in serious air pollution. In recent years, both at home and abroad are transforming the existing coking equipment to meet the increasingly stringent environmental protection regulations, and looking for more economical methods to produce high-q...

AI Technical Summary

Problems solved by technology

However, there are still some problems in this device: due to the low strength of the horizontal fire path, the amount of bricks used is increased to ensure the strength; the horizontal fire path limits the increase in the width of the coke oven; the regenerator is used to preheat the air, which makes the structure of the coke oven complex and It increases the investment and complicates the operation; the dry quenching of coke with inert gas will increase the medium gas continuously, and dust will enter the gas, resulting in a complex structure, high investment and large space occupation; the sensible heat of hot gas is not recovered and given Unreasonable coal distribution, etc.
