Abstract

The invention relates to the technical field of reactors and particularly belongs to a control method of a reformed alkali production reactor. CO2 is introduced into a telescopic rod moving cavity through a CO2 inlet channel and is then guided to a reaction cavity through a right channel; CO2 reacts with an aqueous solution of ammonia gas to generate NH4HCO3; a telescopic rod drives a conical plugto continuously descend until the conical plug presses the bottom of a cylindrical baffle bracket; an Nacl solution flows from an Nacl cavity into the reaction cavity; a filtering device filters outNH4cl, and NH4cl flows into the telescopic rod moving cavity through the right channel and then flows out through an NH4cl outlet pipeline; the NaHCO3 precipitate is left in the reaction cavity and decomposed; and CO2 enters a CO2 storage tank through a CO2 outlet channel for use in the next reaction. The method provided by invention has the advantages that the self-control advancement of reactionprocesses can be realized, the reaction rate can be effectively controlled, and multiple steps of reactions can be completed in one device.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a modified soda-making reactor and a control method thereof. Background technique [0002] In the production of soda ash, the ammonia-soda method is gradually replaced by the combined soda-making method because of its low utilization rate of salt raw materials and the production of difficult-to-handle calcium chloride. The combined soda production method realizes the alternating cycle of producing the main product soda ash and the by-product ammonium chloride. The existing soda production equipment will complete each step of reaction in different storage tanks. Design a soda production reaction device that can effectively improve the reaction efficiency is very necessary. Contents of the invention [0003] In view of the defects of the prior art, the present invention provides a modified soda-making reactor and its control method, which can realize the self-controlled advance...
