Description

TECHNICAL FIELD

[0001] The utility model relates to furaldehyde exhaust gas treatment technology field, especially in a kind of furaldehyde exhaust gas collection equipment. BACKGROUND

[0002] In the production process of furaldehyde, a large amount of waste gas will be produced, which is mainly derived from the residual waste gas in the hydrolysis kettle after raw material hydrolysis. The waste gas contains a small amount of product, acetic acid and other light and heavy components. In order to improve the comprehensive yield without affecting the subsequent hydrolysis, it can only be discharged. If these waste gases are not effectively treated and directly discharged into the atmosphere, it will cause pollution to the environment. At present, there are some technologies and methods for furaldehyde plant waste gas treatment. The most commonly used methods are activated carbon adsorption or zeolite plus catalytic combustion waste gas treatment method. When treating furaldehyde exhaust gas, the exhaust gas is transported from the hydrolysis reactor to the waste gas treatment equipment through the gas guide pipeline. In order to reduce the working load of the waste gas treatment equipment, increase the service life of the consumables in the waste gas treatment equipment, and reduce the cost of using the waste gas treatment equipment, the waste gas is usually first transported to the gas collection chamber for spray pretreatment, so as to cool the waste gas and remove part of the large particle impurities in the waste gas. When the waste gas is sprayed, whether the distribution of the waste gas is uniform will affect the effect of waste gas spraying. When the waste gas is not uniformly distributed, the effect of waste gas spraying will be poor, so the working load of the subsequent waste gas treatment equipment will be large. When the waste gas is uniformly distributed, the effect of waste gas spraying will be good, so the working load of the subsequent waste gas treatment equipment will be small.
