Abstract

The invention discloses a formaldehyde tail gas combustion and heat recovery system which comprises an air intake system, an ignition device, a combustion device, an insulation hearth, a secondary air device, a hearth flame-out protection device and a heat recovery system part; the insulation hearth is located at the front of the air intake system; the ignition device is arranged on the inner wall of the rear wall of the insulation hearth and is located above the secondary air device; the combustion device and the secondary air device are located in the insulation hearth; the secondary air device is located above the combustion device and is arranged on the left inner wall and the right inner wall of the insulation hearth; an air outlet of the air intake system communicates with an air inlet of the combustion device; and an air outlet of a blower communicates with an air inlet of the secondary air device. The formaldehyde tail gas combustion and heat recovery system and the operation method of the formaldehyde tail gas combustion and heat recovery system are good in safety and high in heat utilization rate.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection, and in particular relates to a formaldehyde tail gas combustion and heat recovery system and an operation method thereof. Background technique [0002] Formaldehyde is produced by silver method to produce 37% formaldehyde, and the tail gas discharged from the top of the three towers finally contains H 2 About 18-20%, CO, CH 4 , O 2 0.5% each, CO 2 5%, N 2 72-74%, water and trace formaldehyde, methanol, etc. About 20% of it is combustible gas, and its calorific value is about 526Kcal / Nm 3 , if it is used to burn to generate steam, it can not only eliminate pollution, but also generate steam. Formaldehyde tail gas is poor gas, mainly containing about 20% H 2 , The hydrogen-oxygen reaction is an explosive reaction. Therefore, how to use it safely and efficiently has become a key issue. [0003] At present, although general formaldehyde production plants are equipped with formald...
