Abstract

The invention provides a steam boiler desalting and descaling system and an operation method thereof. The steam boiler desalting and descaling system comprises: a boiler; a desalting and descaling device located at the upstream position of the boiler, wherein the steam port of the desalting and descaling device is communicated with the steam inlet of the boiler; a heating structure provided with aseparator and a heat exchange reflux pipeline, wherein the inlet of the separator is communicated with the steam discharge outlet of the boiler, and the separator is communicated to the desalting anddescaling device through the heat exchange reflux pipeline so as to introduce high-pressure hot steam generated by the boiler into the desalting and descaling device and heat purified sewage; and a pressurizing device for pressurizing the steam entering the boiler. The problems of scaling salting-out and pipeline blockage of a boiler system and a rear-section pipeline of the boiler system in theprior art are solved.

Description

technical field [0001] The invention relates to the field of boiler desalination and scale reduction systems, in particular to a steam boiler desalination and scale reduction system and an operating method thereof. Background technique [0002] In the heavy oil production process, hot steam injection is often used for production. Steam generation equipment such as wet steam boilers and overheating boilers are widely used in oil fields to produce steam. If the boiler water is heavy oil purified sewage, because it contains a large amount of salts such as sodium salt, calcium salt, dissolved silicon, etc., after the heavy oil purified sewage enters the boiler, it will be converted into steam in the boiler, and salting out will easily occur in the boiler system And fouling, causing blockage to the system, affecting normal production, and posing safety hazards. [0003] At present, the existing patents are all about cleaning the salty steam generated by the sewage purification ...
