Problems solved by technology
Compared with the traditional fixed bed production process, the slurry bed is more efficient, but there are still hydrogenation and oxidation processes in the production process, and inherent dangers always exist. At present, there are few technologies specifically for the safety control of this process, and the safety of the production process is limited. The security control of the system is not perfect; moreover, some controls have a high rate of false alarms, and false triggering problems caused by instrument failures may also occur

The invention discloses a safety control system of a slurry reactor anthraquinone process hydrogen peroxide device. The safety control system comprises one or more of the following components: an interlocking module configured to perform interlocking control on feeding and discharging of a hydrogenation reactor according to a pressure detection value, a temperature detection value and a gas phaseoxygen content detection value obtained on the hydrogenation reactor, an interlocking module configured to perform interlocking control on feeding and discharging of an oxidation reactor according toa temperature detection value and a gas phase oxygen content detection value obtained on the oxidation reactor, an interlocking module configured to perform interlocking control on feeding and discharging of an extraction tower according to a temperature detection value and a gas phase oxygen content detection value obtained on the extraction tower, and an interlocking module configured to performinterlocking control on feeding and discharging of a purification tower according to a temperature detection value obtained on the purification tower. According to the safety control system, the problems of poor safety of hydrogen peroxide production control, high false alarm rate of some control and false triggering caused by instrument faults in the prior art are solved.
Description
technical field [0001] The invention relates to the technical field of safe production of hydrogen peroxide, in particular to a safety control system of a slurry bed anthraquinone method hydrogen peroxide device. Background technique [0002] Hydrogen peroxide is one of the main basic chemical products in the world. At present, the production process of hydrogen peroxide by anthraquinone method is its main production method. This technology has become mature, but domestic manufacturers generally use the fixed bed production process, which has only begun to develop and produce in recent years. More efficient slurry bed process. Compared with the traditional fixed bed production process, the slurry bed is more efficient, but there are still hydrogenation and oxidation processes in the production process, and inherent dangers always exist. The system security control is not perfect; and some controls have a high false alarm rate, and there will be false triggering problems cau...
