Abstract

The invention relates to the technical field of waste gas treatment, and particularly discloses a safe and efficient catalytic device, which comprises a shell, a heat exchanger, a heater and a primarycatalyst. The primary catalyst is flatly laid on a catalyst mounting grid, and the catalyst is filled in a bricked manner, so that the problem of efficiency reduction caused by waste gas leakage treatment due to a gap between the catalyst is solved; a separation net is arranged between the upper and lower adjacent layers of catalyst, the separation net enables the upper-layer catalyst to achievethe purpose of suspension, prevents the upper-layer catalyst from blocking air holes of the lower-layer catalyst, guarantees smooth air exhaust and stable temperature, and prevents a heat storage phenomenon. The device is further provided with a secondary catalyst, a lengthened reaction area is reserved, a sufficient reaction and mixed flow space is provided for catalytic reaction, and catalytic efficiency is provided; meanwhile, potential safety hazards caused by heat accumulation in the catalyst due to catalyst stacking can be prevented, safety performance is provided, and the device has theadvantages of smooth air exhaust, stable temperature, safety and high efficiency.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to a safe and efficient catalytic device. Background technique [0002] VOC stands for Volatile Organic Compounds, which have a huge impact on human health. When the VOC in the room reaches a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short time. decline and other serious consequences. VOC outdoors mainly comes from fuel combustion and transportation; indoors mainly comes from combustion products such as coal and natural gas, smoke from smoking, heating and cooking, construction and decoration materials, furniture, household appliances, cleaning agents and human body emissions. [0003] VOC is an organic volatile substance that is easy to burn. The existing VOC treatment method is adsorption-desorption, followed by catalytic oxidation combustion treatment. This treatment is relatively complete and can basically convert VOC ...
