Abstract

The invention discloses a safety interlock control system and a control method for a fixed bed anthraquinone process hydrogen peroxide device. Temperature measurement instruments are arranged in an oxidation tower and an extraction tower; the temperature and the temperature rising rates of the oxidation tower and the extraction tower are set into interlock values; automatic opening and closing of a valve under an abnormal working condition are achieved; and hazardous materials are rapidly withdrawn to an accident tank or an accident pond. Through the safety interlock control system, the hydrogen peroxide production process is controlled; safe production of the device is ensured; and a firing explosion accident is avoided.

Description

technical field [0001] The invention relates to the technical field of hydrogen peroxide production, in particular to a safety interlock control system and a control method of a fixed-bed anthraquinone method hydrogen peroxide device. Background technique [0002] At present, domestic hydrogen peroxide production devices basically adopt the fixed-bed anthraquinone process. Since hydrogen peroxide is prone to decompose and heat up under alkaline conditions or encounter metal ions, etc., it may cause the working fluid in the device to burn or even explode, seriously affecting the safe production of the device. If certain measures can be taken to automatically remove the decomposed materials from the system under abnormal working conditions and realize unmanned operation, the probability of serious accidents will be greatly reduced, and personal injury accidents of on-site operators will be avoided. Reduce losses. Contents of the invention [0003] The purpose of the presen...
