Description

Technical Field

[0001] The utility model relates to the technical field of evaporating kettles, in particular to an evaporating kettle used for the concentration processing of neopentyl glycol. Background Art

[0002] An evaporator is a device used to convert liquid into steam or evaporate it into dry solid. When the reactor performs chemical reactions, waste gas is easily generated due to the chemical mixing reaction. The waste gas contains dust and harmful gases. If the waste gas is directly discharged into the air, it is easy to cause pollution to the surrounding environment and the health of the surrounding residents. This requires the waste gas generated by the reactor to be treated. In the prior art, there are already treatment equipment for the treatment of waste gas. Generally, the waste gas is filtered through a filter device. However, due to the high temperature of the steam and the presence of moisture, it is easy to cause the filter device to become wet, causing dust and impurities to adhere to the filter device, resulting in blockage. In addition, the moisture in the steam will also contain some recyclable substances. If it cannot be effectively recovered, it will also cause a waste of resources. For this reason, the utility model proposes an evaporator for the concentration and processing of neopentyl glycol to solve the above problems. Utility Model Content
