Problems solved by technology
[0004] Enameled wire will use organic solvents in the production process. The remaining gas after the catalytic combustion of organic solvents in the oven at about 600 degrees is difficult to be treated by high-temperature combustion. It can only be covered by spraying, but it cannot be cost-effective. To some extent, secondary pollution such as waste water will be generated, and the pungent organic waste gas will eventually escape from the cover and disperse in the distance

The invention discloses a waste gas low-temperature catalysis treatment device. The waste gas low-temperature catalysis treatment device is arranged in a baking furnace air outlet passage, and is a multilayer laminated filter; molecular sieve type catalyst particles are arranged in the filter; the catalyst particles are prepared from one kind of materials from ceramic dichroite, lanthanum oxide, cerium oxide, gold, silver and platinum; the catalysis temperature range of the catalyst particles is 150 to 500 DEG C. The catalyst particles do not need additional heating; the organic waste gas can be subjected to catalytic oxidation in the in-furnace temperature environment; meanwhile, the organic waste gas can be more easily adsorbed through the molecular sieve structures; the catalysis efficiency is improved. The organic waste gas is decomposed into CO2 and H2O after the catalytic oxidation decomposition; the pungent smell is eliminated; cleanness and environment protection are realized.
Description
[0001] Technical field: [0002] The invention belongs to the technical field of waste gas treatment, in particular to a low-temperature catalytic treatment device for waste gas. [0003] Background technique: [0004] Enameled wire will use organic solvents in the production process. The remaining gas after the catalytic combustion of organic solvents in the oven at about 600 degrees is difficult to be treated by high-temperature combustion. It can only be covered by spraying, but it cannot be cost-effective. To some extent, secondary pollution such as waste water will be generated, and the pungent organic waste gas will eventually escape from the cover and drift away in the distance. [0005] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to t...
