The invention relates to a separator, in particular to a steam-dryness vertical sampling steam-water separator of a petroleum-industry heating-power-exploitation underground thickened oil steam-injection boiler. The vertical sampling steam-water separator is used for high-pressure saturated-steam dryness detection, and comprises a vertical external sleeve, an upper sealing head is arranged at theupper end of the external sleeve, a lower sealing head is arranged at the lower end of the external sleeve, a steam inlet pipe is inserted into from the upper sealing head, an air collecting pipe extends out of the lower sealing head, guide holes are formed in the upper pipe wall of the air collecting pipe, and a sampling pipe nozzle is arranged on the side wall of the lower sealing head. The vertical sampling steam-water separator has the advantages that saturated water in wet saturated steam is separated out, the ion concentration of the saturated water is assayed and separated, and the dryness of the wet saturated steam can be calculated. A stop valve is arranged at a sampling water outlet, the flow amount of the sampling water can be controlled, the very small amount of saturated wateronly needs to be taken, and the dryness can be assayed.
Description
technical field [0001] The invention relates to a separator, in particular to a steam dryness vertical sampling steam-water separator for an underground heavy oil steam injection boiler in the thermal exploitation of petroleum industry, which is used for detecting the dryness of high-pressure saturated steam. Background technique [0002] At present, most of the oilfield steam injection boilers in use in China are saturated steam boilers, and their feed water is dehardened and demineralized water. Therefore, the dryness of the steam at the boiler outlet is required to be controlled below 80%, and 20% of the water should be retained to dissolve the salt in the water. To ensure safe operation of the boiler. The dryness of the steam determines the heat carried by the steam per unit mass. For steam injection and oil recovery, the higher the dryness of the steam, the more heat carried by the steam per unit mass, and the better the oil recovery effect. Therefore, the control of s...
