APPARATUS AND METHOD OF ACETYLENE PRODUCTION Russian patent published in 1995 - IPC

FIELD: acetylene production, acetylene generators. SUBSTANCE: products acetylene and calcium chloride, reactants calcium carbide and water are produced as a result of consequent stages of reaction. At first stage calcium carbide is loaded in reactor with increasing stream, that has water up to 60 90 Reaction products and non-reacted raw materials are drawn into secondary reactor with gas-shaped acetylene discharge by removal of calcium hydroxide and introduction of hydrogen chloride in reaction to produce calcium chloride. Exothermic reaction produced heat is used to dry produced calcium chloride and to increase its value. Apparatus for acetylene production has: primary and secondary reactors, connected to each other by pipeline, used to transport liquid phase and acetylene; branch pipes to feed water and calcium carbide in primary reactor; branch pie for calcium hydroxide removal from lower part of primary and secondary reactors; branch pipe to discharge acetylene from secondary reactor; located in central part of secondary reactor stirring tool, embraced by connected to bottom of the reactor vertical ring-type partition; circulation pipeline, that connects space from outer side of ring-type partition of secondary reactor with lower part of primary reactor, that is separated from upper part by narrowing, connected to branch pipe for removal of calcium hydroxide from secondary reactor; neutralizer of calcium hydroxide with hydrogen chloride or hydrochloride acid feeder; connected to neutralizer and primary reactor calcium chloride dryer. EFFECT: increase production of dry acetylene. 6 cl, 4 dwg
