Three common external damages of electric heating reactor
Source: Stainless steel reactor, resin reactor, pressure vessel tank - Wuxi Huaxuan Equipment Technology Co., Ltd |Published on: July 27, 2020
The utility model is composed of a kettle, an electric kettle, a reaction kettle, a supporting device and a shaft sealing cover. Generally, there are anchor type, paddle type, turbine type, propulsion type or frame type, etc. when the height diameter ratio of the mixing device is large, multi-layer mixing blades can be used, or optional according to the requirements of users. The jacket is set outside the kettle wall, or the heat exchange surface is set in the reactor, and the heat transfer can be carried out by external circulation.
The heating methods include electric heating, hot water heating, circulating heat transfer oil heating, far-infrared heating, external (internal) coil heating, etc. the cooling methods are jacket cooling, coil cooling in kettle, stirring paddle, etc. The supporting base has supporting type or ear type support, etc. Gear reducer should be used when the speed is more than 160 rpm. The number of holes, specifications or other requirements can be designed and manufactured according to the user's requirements.
There are three kinds of common external damage of electric heating reactor
1. External corrosion. The equipment is composed of a heating layer and an external iron tire. Iron, as a medium, has no corrosion resistance to acids and alkalis. If the reaction kettle cover or pipe joint is not tightened or the sealing gasket fails in the production process, there will be acid leakage, which will corrode the iron tire on the outer layer of electric heating reactor equipment.
2. Corrosion of supports. In the installation, the support or other supporting parts are sometimes directly installed on the floor, and the electric heating is installed reaction kettle Due to the long-term production operation, the floor may deposit corrosive media, which will corrode the supporting parts of our electric heating reactor equipment, resulting in changes in the supporting force of each support, resulting in the change of internal stress, resulting in the damage of the heating layer in the production process.
3. Stress at the nozzle. On the electric heating reactor, when the steel pipe is connected with the pipe orifice, the pipe will be damaged due to the thermal deformation of the vessel and the stress caused by the heating or cooling of the pipe.
