High-efficiency, long-life, low-coking and low-blocking regenerator

Abstract

The invention belongs to the technical field of regenerators, in particular to a high-efficiency, long-life, low-coking and low-blocking regenerator. The high-efficiency, long-life, low-coking and low-blocking regenerator comprise a flue gas inlet pipeline, a regenerator wall and a flue gas outlet pipeline, and the flue gas inlet pipeline, the regenerator wall and the flue gas outlet pipeline arearranged in the same direction, wherein a container formed by the regenerator wall contains a large number of heat storage balls, the flue gas inlet area and the flue gas exhaust outlet area use the large-size heat storage balls, and the particle sizes of the heat storage balls in the middle of the regenerator gradually decrease in the flue gas flow direction. The design scheme that the particle sizes of the heat storage balls gradually decrease in the flue gas flow direction is adopted in the middle of the regenerator, the breaking probability of the heat storage balls caused by thermal stress can be greatly reduced, the service life of the heat storage balls is significantly prolonged, the cycle for replacing the heat storage balls during use of the regenerator is prolonged, the flue gas inlet pipeline, the regenerator wall and the flue gas outlet pipeline are arranged in the same direction, the restricted vertical staggering of the air intake and exhaust is not required in the technical scheme, and the high-efficiency, long-life, low-coking and low-blocking regenerator is more convenient for the staff to operate and use .

Description

technical field [0001] The invention belongs to the technical field of regenerators, and in particular relates to a regenerator with high efficiency, long life, low coking and low blockage. Background technique [0002] Combustion is widely used in metallurgy, manufacturing and other industrial fields. The conventional direct combustion technology generates a lot of energy waste and causes environmental pollution due to the high temperature of the exhaust gas discharged, while the regenerative high-temperature air combustion technology recovers the energy of the exhaust gas discharged from combustion. , and preheat the combustion elements (combustion material and air), thereby significantly improving combustion efficiency and saving a lot of energy. Some data show that for every 100°C increase in the air preheating temperature, the furnace output can be increased by 2%, and the fuel can be saved by 5%. With regenerative combustion, the preheating temperature of the air is a...

AI Technical Summary

Problems solved by technology

[0004] ① The flue gas inlet area is easily blocked by soot

[0005] ②The smoke outlet area is easy to coke

[0006] ③The heat storage ball is fragile and needs to be replaced regularly

When working in the regenerator, high-temperature exhaust gas and low-temperature air alternately enter the regenerator periodically, causing fatigue failure of the heat storage ball under thermal stress

The rupture of the heat storage ball will seriously block the channel and deteriorate the performance of the heat storage chamber, so the heat storage ball needs to be replaced regularly

[0007] ④The channel in the heat storage chamber is not fully utilized, and the efficiency is low

However, this patent still cannot completely improve the above problems, and some problems are also exposed. For example, in its technical solution: ① intake and exhaust must be horizontal; ② intake and exhaust must be vertically staggered; resulting in the use of regenerators still inconvenient
