Description

Technical Field

[0001] This utility model relates to the field of impregnated paper technology, and in particular to a waste gas combustion device for impregnated paper processing. Background Technology

[0002] Impregnated paper refers to offset paper that has been impregnated with amino resin on solid-color base paper or printed decorative paper, dried to a certain extent, and then hot-pressed together or bonded to a wood-based panel substrate. The preparation process of impregnated paper is as follows: glue preparation → glue mixing → adding curing agent, release agent, penetrant, dust removal agent, etc. → first impregnation → first drying → second impregnation → second drying → cooling and cutting.

[0003] During the preparation of PVC-impregnated paper, multiple drying and impregnation processes are required. During the drying process, a large amount of harmful gases are easily generated. Currently, the method for treating these harmful gases is through combustion equipment. However, current waste gas combustion equipment does not recover and utilize the waste heat generated during combustion, and the untreated waste gas pollutes the environment, affecting the environmental protection effect of PVC-impregnated paper waste gas treatment.
