Non-stop production decolorization system based on working condition of continuously producing steroid drugs

Abstract

The invention provides a non-stop production decolorization system based on the working condition of continuous production of steroid drugs, and relates to the technical field of steroid drug production. The non-stop production decolorization system sequentially comprises an activated carbon filtering and cleaning device, an activated carbon activating and drying device, an activated carbon smashing device and a plurality of reaction tanks; a filtering feeding hole is formed above the activated carbon filtering and cleaning device, a filtering carbon outlet and a filtering liquid outlet pipe are arranged below the activated carbon filtering and cleaning device, and a filtering mechanism is arranged inside the device; the activated carbon activating and drying device is used for preheatingactivated carbon discharged from the filtering carbon outlet, introducing steam to activate, and performing heating and drying; the activated carbon crushing device is used for crushing the dried activated carbon; a reaction tank feeding hole and a reaction tank feeding hole are formed above the reaction tank, and a reaction tank discharging hole is formed below the reaction tank; a color detectoris arranged on a pipeline of the filtering liquid outlet pipe, and unqualified liquid is detected to flow back into the reaction tank. The system is used in steroid drug production working conditions, decoloration treatment is carried out on intermediates, and centralized treatment and control without stopping production are achieved.

Description

technical field [0001] The invention relates to the technical field of steroid drug production, in particular to a non-stop decolorization system based on continuous production of steroid drug working conditions. Background technique [0002] Steroid drugs are mainly corticosteroid drugs and sex hormone drugs, which occupy an important position in the chemical drug system. The discovery and successful synthesis of steroid drugs are known as one of the two major advances in the pharmaceutical industry in the 20th century. Steroidal drugs play a very important role in regulating the body, have strong anti-infection, anti-allergy, anti-virus and anti-shock pharmacological effects, can improve protein metabolism, restore and enhance physical strength, diuretic and blood pressure, and are widely used in the treatment of Rheumatoid arthritis, bronchial asthma, eczema and other skin diseases, anaphylactic shock, prostatitis, Addison's and other endocrine diseases can also be used f...

Problems solved by technology

The traditional decolorization process currently used is to put these intermediates, decolorizers, and activated carbon into the reactor, and after a period of reaction, filter and separate the activated carbon. However, in this production process, the manual process The operation is usually cumbersome and not suitable for the high-efficiency and high-quality production requirements of the factory. Therefore, the applicant has developed and designed a series of non-stop production decolorization systems for this decolorization problem.
