Problems solved by technology
[0003] However, during the distillation process, the interior of the distiller and the reboiler are seriously blocked. If the blockage is not cleaned in time, it will greatly affect the mass and heat transfer of the distillation system.
[0004] However, the cleaning method of traditional DOTP distillers mainly adopts the method of soaking after stopping the whole system, and the system takes a long time to stop, clean and start up, resulting in too long freshening cycle and affecting the cleaning efficiency of the distiller. At the same time, after cleaning the traditional distiller, The cleaning liquid is recycled directly without filtration, and the cleaning liquid is easy to be mixed with impurities, which will lead to blockage of the distillation system pipeline, thus affecting the work of the distiller

The invention discloses a distiller cleaning method for DOTP production, and relates to the technical field of DOTP production equipment. The distiller cleaning method for DOTP production comprises the following steps that a proper amount of cleaning agent and water are correspondingly added into a mixing box for dilution to obtain cleaning water; the mixing box and the distiller for DOTP production are connected through a pipeline; a flow path between the mixing box and the distiller for DOTP production is opened, so that the cleaning water in the mixing box is introduced into the distiller through the pipeline to clean the distiller; and after cleaning, the cleaning agent flows back into the mixing box for next cleaning and use. According to the distiller cleaning method, on-line circulation cleaning can be realized, the whole distillation system does not need to be stopped, the fresh cycle can be effectively reduced, the cleaning time of the distiller is greatly shortened, the cleaning efficiency of the distiller is improved, time and labor are saved, and the cleaning cost of the distiller is reduced.
Description
technical field [0001] The invention belongs to the technical field of DOTP production equipment, and in particular relates to a method for cleaning a distiller used for DOTP production. Background technique [0002] Distillation is one of the purification methods, and in the production process of DOTP, by-products are easily produced, so DOTP needs to be distilled by distillation equipment to remove the by-products doped inside and obtain high-purity DOTP. [0003] However, during the distillation process, the interior of the distiller and the reboiler are seriously blocked. If the blockage is not cleaned in time, the mass transfer and heat transfer of the distillation system will be greatly affected. [0004] However, the cleaning method of traditional DOTP distillers mainly adopts the method of soaking after stopping the whole system, and the system takes a long time to stop, clean and start up, resulting in too long freshening cycle and affecting the cleaning efficiency ...
