Embodiment Construction
[0004] The anti-corrosion technology of the present invention is to use bauxite, kaolin or calcium aluminate powder or its mixture as the material of the normal pressure reactor body, use calcium chloride or sodium fluorosilicate as the curing agent, and acid-resistant cement and water. After the adhesive sticks the industrial acid-resistant magnetic plate on the inner wall of the reactor, it is cured for 3-5 days, and acidified with acid for 10-30 days, and the anti-corrosion atmospheric pressure for the production of polyaluminum chloride with aluminum-containing mineral powder is made. Reactor.

The invention discloses an anti-corrosion technique for a normal-pressure reaction kettle for producing polyaluminium chloride, relates to an anti-corrosion technique, in particular to an anti-corrosion technique for a normal-pressure reaction kettle for producing polyaluminium chloride, and aims to provide an anti-corrosion technique for a normal-pressure reaction kettle for producing polyaluminium chloride with high anti-corrosion performance and long service life. The invention adopts a technical proposal that the normal-pressure reaction kettle for producing the polyaluminium chloride by the anti-corrosion technique comprises a kettle body and industrial acid-resistant magnetic plates, wherein the kettle body is made of bauxite, kaolin or calcium aluminate or mixture thereof, an adhesive for adhering the industrial acid-resistant magnetic plates is slurry of acid-resistant cement and calcium chloride or sodium silicofluoride and water, and the calcium chloride or the sodium silicofluoride accounts for 5 to 30 percent of the acid-resistant cement. The anti-corrosion technique is used for the normal-pressure reaction kettle for producing the polyaluminium chloride.
Description
Technical field: [0001] The invention relates to an anti-corrosion technology, in particular to an anti-corrosion technology for an atmospheric pressure reactor used for producing polyaluminum chloride. Background technique: [0002] When producing polyaluminum chloride, due to the strong corrosiveness in its reaction, the corrosion resistance of the existing normal pressure reactor is low, the life of the reactor is very short, not only the production cost is high, but the reactor is often repairs, resulting in downtime. Invention content: [0003] The object of the present invention is to provide a kind of anticorrosion technology of the atmospheric pressure reactor used for producing polyaluminum chloride with high anticorrosion performance and long service life. The technical scheme of the present invention is an anticorrosion technology for an atmospheric pressure reactor for producing polyaluminum chloride, comprising a kettle body and an industrial acid-resistant m...
