Steam-water separator of horizontal type steam-injection boiler

Abstract

The invention relates to a steam-water separation device of a steam-injection boiler, in particular to a steam-water separator of a horizontal type steam-injection boiler. The steam-water separator of the horizontal type steam-injection boiler solves the problems that when a steam-water mixture of the dryness less than 80% is injected into a heavy oil mine, the oil recovery efficiency is low, the oil recovery requirements can not be met, large scale can not be achieved, and maintenance is inconvenient. A steam outlet pipe connector and a spray water outlet pipe connector are communicated to a barrel, a cross partition board is installed on the inner wall of the bottom of the barrel, a corrugated board dryer is installed on the inner wall of the top of the barrel, diversion devices, primary separator bodies and secondary separator bodies are arranged inside the barrel from bottom to top, the lower ends of the primary separator bodies are connected with the diversion devices, the upper ends of the primary separator bodies are connected with the secondary separator bodies, the two obverse faces of the two diversion devices on the left side and the two diversion devices on the right side are respectively connected with the barrel through a bent board, the two reverse faces of the two diversion devices on the left side and the two diversion devices on the right side are respectively connected with the barrel through an arc board, and water return pipes are communicated with the lower end of the corrugated board dryer. According to the steam-water separator of the horizontal type steam-injection boiler, large scale is achieved, and maintenance is convenient.

Description

technical field [0001] The invention relates to a steam-water separation device for a steam injection boiler, which separates a steam-water mixture into saturated steam and saturated water with a dryness above 99% through multi-stage separation. Background technique [0002] The exploitation of heavy oil usually requires the injection of steam to increase the extraction capacity. [0003] At present, gas-fired once-through boiler systems are usually used to produce steam in heavy oil production. However, due to the limitation of the geographical environment of the oil field, the mineral content in the boiler feed water is very high, and the feed water must be treated to meet the requirements of the boiler operation, which greatly increases the cost of steam injection. In order to ensure the operation of the boiler and avoid salt accumulation, when designing the boiler, the parameters of the boiler outlet are lowered to a state of steam-water mixture below 80% dryness. This...
