When the glass lined reaction tank is heated by electricity, the equipment is relatively light and simple, the temperature is easy to adjust, and there is no need for water pump, stove, chimney and other facilities. The start-up is also very simple, with low risk and low cost, but the operation cost is higher than other heating methods. What are the precautions for carbonization of this reaction tank? The following is the arrangement of Xiaobian:
Based on the basic design and heating mode of the original glass lined reaction tank, some adjustments have been made to the bottom of the reactor. Because all problems are caused by the precipitation of solid reactants, the main solution is to avoid precipitation even without mixing or stirring. This can be achieved by adding an auxiliary bottom, which is slightly higher than the actual bottom, leaving a gap of 3-10 cm. In this way, the solid reactant will be deposited on the auxiliary bottom without forming an insulating layer on the actual bottom of the glass lined reaction tank.
In fact, the heat transfer is carried out through the convection between the gaps at the bottom of the glass lined reaction tank equipment, and the auxiliary bottom is made of high-strength enamel glass. There are many holes on it, and the pore size is slightly smaller than the particle size of the reaction material, so the screen is cut into a circle. Its edges bend downward as a support. When the solid reaction material is heavily loaded, a metal ring can be added under the auxiliary bottom as a support. Therefore, before using the reaction tank, we need to take preventive measures to carbonize the equipment, and we need to clean and maintain the equipment regularly to reduce the possibility of failure and prolong its service life.
The glass lined reaction tank makes rational use of heat energy, selects certain process operating conditions, strengthens thermal insulation measures, improves heat transfer efficiency, reduces heat loss to a relatively low level, and makes full comprehensive use of waste heat or heat energy generated by reaction.
