A kind of production process and equipment of methallyl alcohol

Abstract

The invention relates to the technical field of methallyl alcohol, in particular to a production process and equipment for methallyl alcohol, including an oxygenation reactor, a first cylinder, a hydrogenation reactor and an incinerator, the oxygenation reactor There is a stirring mechanism inside, and the stirring mechanism includes a stirring rod. Several rotating blades are arranged on the outer wall of the stirring rod, and the upper surface of the rotating blade is provided with evenly arranged scale strips. The device passes through the lower surface of the rotating blade. The upper branch blade increases the ring diameter of the rotary blade to enlarge and mix the materials, and at the same time, the scale strips on the upper surface of the rotary blade can block and move the material, and then the first airtight push plate can shrink the inner cavity of the oxygenation reactor, so that The inner cavity is pressurized and fully mixed, and the incinerator is used for waste utilization through the exhaust gas methane dye. At the same time, the heat generated by the incinerator is circulated to the oxygenation reactor and hydrogenation reactor through water, and the water pipe is filtered through the filter mechanism. This way the pipes will not be clogged with scale.

Description

technical field [0001] The invention relates to the technical field of methallyl alcohol, in particular to a production process and equipment for methallyl alcohol. Background technique [0002] Methallyl alcohol, also known as "isobutenol", is an important organic intermediate used in the synthesis of perfumes, resins, etc. Use methallyl alcohol and ethylene oxide as raw materials to synthesize methallyl alcohol polyoxyethylene ether (HPEG), which is used in a new generation of high-performance concrete water reducer. Methallyl alcohol polyoxyethylene ether is easily soluble in water And a variety of organic solvents, it is an important raw material for a new generation of polycarboxylate superplasticizer. The polycarboxylate high-efficiency superplasticizer synthesized by this product has high-efficiency particle dispersion and retention capabilities, and has many advantages such as high water-reducing rate, low cement usage, good reinforcement effect, good durability, no...

AI Technical Summary

Problems solved by technology

[0003] (1) During the production process of methallyl alcohol, it needs to be fully mixed by stirring, and the existing reactor stirring can only work on the maximum diameter range of the blade, which will make the mixing efficiency very low ;

[0004] (2) In the process of producing methallyl alcohol, the methane waste produced cannot be fully utilized, thereby causing a large amount of energy waste;

[0005] (3) During the production process of methallyl alcohol, it needs to be heated when processing methallyl alcohol, and the heated water pipe is prone to produce a large amount of scale during long-term use, so that the heating of the water pipe is affected certain influence
