Abstract

The invention discloses a CO boiler with the ash removing function. The CO boiler comprises a first vertical flue, a horizontal flue and a second vertical flue. The first vertical flue is provided with a combustion chamber. The combustion chamber is provided with ash baffles. An externally-hung ash storage bin is arranged on the outer side of the portion, adjacent to the second vertical flue, of the flue wall of the combustion chamber. The first vertical flue is provided with an ash discharge port which is communicated with the ash storage bin. The ash baffles are of the structure that the baffles are arranged in multiple layers in a staggered mode. Each ash baffle is obliquely arranged, wherein the outer end of the ash baffle is higher than the inner end of the ash baffle. According to the CO boiler with the ash removing function, the ash baffles arranged in the CO boiler can remove most of smoke dust contained in flue gas, as a result, the problem of equipment abrasion caused by the smoke dust can be solved to the maximum extent, the flue gas processing technology is optimized, energy consumption is lowered, and investment is reduced.

Description

technical field [0001] The invention relates to a CO waste heat boiler for regenerating flue gas from catalytic cracking (FCC) in an oil refinery, in particular to a CO boiler with ash removal and denitrification functions. Background technique [0002] Nitrogen oxides (NOx) are one of the main sources of air pollution. Nitrogen oxides include compounds such as nitrous oxide (N 2 O), nitric oxide (NO), nitrogen dioxide (NO 2 ), nitrogen trioxide (N 2 o 3 ), dinitrogen tetroxide (N 2 o 4 ) and dinitrogen pentoxide (N 2 o 5 )Wait. Except for nitrogen dioxide, other nitrogen oxides are extremely unstable, and turn into nitrogen dioxide and nitric oxide when exposed to light, humidity or heat, and nitrogen monoxide turns into nitrogen dioxide. Therefore, exposure to several gas mixtures in the occupational environment is often called gunpowder (gas), mainly nitric oxide and nitrogen dioxide, and nitrogen dioxide is the main one. NOx has different degrees of toxicity, a...
