Abstract
The invention discloses a novel steam consumption saving process and device for dissolving solid water glass. The process includes the following steps of connecting an emptying opening and a heating opening of each of at least two static pressure kettles to a pipeline, and conveying released flashing steam through the corresponding emptying opening and the pipeline into the heating openings of the other static pressure kettles to heat materials in the static pressure kettles when one static pressure kettle is decompressed so that the decompression of the static pressure kettle can be completed. Loads on a heat recovery device are reduced; since the static pressure kettles are decompressed first and then material production is conducted, pressure in the kettles is low, pressure is reduced in subsequent heat recovery, and recovery efficiency is improved.
