Abstract

The invention discloses a formaldehyde byproduct steam tail gas processor. The formaldehyde byproduct steam tail gas processor comprises a processor body; the processor body is provided with a hot water section, an upper tail gas air preheating section, a middle heat exchange section and a bottom combustion section in sequence from top to bottom; the upper tail gas air preheating section is provided with a preheating front air inlet at the upper part of one side and a preheating back air outlet at the lower part; the upper tail gas air preheating section is provided with a preheating front tail gas inlet at the upper part of the other side and a preheating back tail gas outlet at the lower part; a steam exhaust port is formed in the upper part of one side of a middle heat exchange section,and a hot water inlet is formed in the lower part; an air inlet is formed in one side of a bottom combustion section; and a tail gas inlet is formed in the other side of the bottom combustion section. Compared with the prior art, the formaldehyde byproduct steam tail gas processor adopts automatic operation without needing special operators, and is convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of formaldehyde preparation equipment, and in particular relates to a formaldehyde by-product steam tail gas processor. Background technique [0002] The tail gas discharged from the absorption tower of silver method formaldehyde production contains about 16%-21% hydrogen, and also contains: CO, CO 2 , N 2 、CH 4 etc., its calorific value is about 1845-2245 kJ / m 3 , We generally use combustion to eliminate the pollution of exhaust gas to the environment, and use the heat energy of combustion to generate steam. [0003] 1. The traditional exhaust processor is mainly composed of: air distributor, gas distributor, combustion chamber (generally formaldehyde device is equipped with formaldehyde combustion disk), heat exchange section, chimney and so on. For the heat exchange section, it is a pressure vessel, and its structure is divided into two types: "tube type" and "tube type". [0004] The resulting chemi...
