Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to trioxane reactor pressure detection technical field, specifically is a kind of trioxane reactor pressure detection device. BACKGROUND
[0002] In the synthesis process of trioxane, a phenomenon that cannot be ignored is that with the continuous chemical reaction, various impurities will gradually accumulate inside the reactor. These impurities not only come from the trace impurities that may exist in the reaction raw materials, but also include by-products and intermediate products generated during the reaction process. They gradually gather in the reaction liquid, causing significant changes in the physical properties of the reaction liquid. The most direct manifestation is that the viscosity of the reaction liquid increases significantly, and the color appears white, which can easily cause the reactor silk screen layer to be blocked. Once the reactor silk screen layer is blocked by impurities, it will directly affect the pressure balance inside the reactor, causing the reactor internal pressure to increase, which can easily break through the reactor silk screen layer, causing equipment damage, and even causing the entire production line to suddenly stop. This not only brings huge economic losses, but also may cause safety accidents and threaten the safety of personnel. In addition, the reactor silk screen blockage can limit the diffusion and transmission of reactants and products inside the reactor. As the degree of blockage increases, the mass transfer resistance increases, which is not conducive to the mixing and dispersion of reactants, thereby reducing the reaction rate and reactor conversion rate. Field inspection cannot timely detect reactor silk screen blockage and reaction liquid whitening.
[0003] Therefore, we propose a trioxane reactor pressure detection device to solve the problems mentioned above. INVENTION CONTENTS

[0023] As Figure 1As shown, the reactor further comprises a reboiler 6, the material inlet and outlet of the reboiler 6 are connected with the reactor body 1, and the reboiler 6 is connected with a steam pipeline 7, and a steam regulating valve group 8 is installed on the steam pipeline 7. The reaction liquid is warmed and vaporized through the reboiler 6, and then the vaporized trioxane gas rises, is filtered through the reactor wire mesh layer 5, and is then guided out through the reactor gas phase pipeline 3. The reaction liquid in the reactor body 1 continues to fall into the reboiler 6 to be warmed and vaporized, forming a circulating flow. The heating function of the reboiler 6 depends on the supply of external steam. In order to achieve this purpose, the external steam enters the reboiler 6 through the steam pipeline 7, and the steam pipeline 7 serves as a heat transfer pipeline to transport high-temperature steam to the inside of the reboiler 6, thereby providing the required heat energy for the reaction liquid.
