Problems solved by technology
[0004] When the maleic anhydride production system is running, if there are foreign matter impurities in the reactor, it will cause irreparable damage to the entire production system
Therefore, testing is required before the operation of the preparation system. Once the equipment is in operation, it will be extremely difficult to detect impurities in the system.

The invention discloses a foreign matter detection system before the operation of a maleic anhydride preparation system, which includes a detection box and a support plate, the detection box is fixed on the top of the support plate, and both sides of the detection box are respectively provided with a punching device and a connecting device. The output end of the punching device is communicated with the detection box, and the detection box is communicated with the reactor through the connection device, an alarm device is fixed on the outside of the detection box, an air pressure sensor is fixed on the inside of the detection box, and the air pressure sensor and the connection device They are respectively electrically connected to the alarm device. The foreign matter detection system before the operation of the maleic anhydride preparation system can detect whether there are foreign matter in the reactor before the maleic anhydride preparation, which ensures the smooth progress of the maleic anhydride reaction, and is applicable It is suitable for different types of reactors and has high practicability.
Description
technical field [0001] The invention relates to the technical field of maleic anhydride preparation, in particular to a foreign matter detection system before the operation of the maleic anhydride preparation system. Background technique [0002] Maleic anhydride, also known as maleic anhydride, maleic anhydride, 2,5-furandione, etc. Orthorhombic colorless acicular or flaky crystals. Has a strong pungent smell, soluble in ethanol, ether and acetone, insoluble in petroleum ether and carbon tetrachloride. The role of hot water into maleic acid. It is mainly used as a raw material for the production of unsaturated polyester resin, alkyd resin, pesticide malathion, high-efficiency and low-toxicity pesticide 4049, and long-acting iodoamine. It is also a comonomer of paint, maleic rosin, polymaleic anhydride, maleic anhydride-styrene copolymer, and an organic chemical raw material for the production of ink additives, papermaking additives, plasticizers, tartaric acid, fumaric a...
