Description

Technical Field

[0001] The utility model relates to the technical field of wet steam dryness detection, and particularly relates to an on-line wet steam dryness detection device. Background Art

[0002] The mass percentage of dry saturated steam contained in each kilogram of wet steam. Steam dryness is an important parameter in the safe operation of oilfield steam injection boilers and also an important indicator affecting the heavy oil thermal recovery effect. The existing high-pressure wet steam dryness detection devices have certain drawbacks when in use. The temperature of the high-pressure wet steam during detection by the existing high-pressure wet steam dryness detection devices is relatively high, and it takes a relatively long process to cool from a high temperature to a low temperature and then turn into water, resulting in a relatively long detection time and not meeting the usage requirements.

[0003] The publication (announcement) number is CN216525304U, which discloses a high-pressure wet steam dryness detection device that records a support frame and a telescopic column. The heights of both the support frame and the telescopic column can be adjusted, which can change the height of the guiding member and the height of the detection bottle, enabling the guiding member to be installed on different oilfield steam injection boilers and making the height of the detection bottle convenient for operators to view, and it is relatively convenient to use; it also records a cooling component. During use, the heat dissipation inner layer and the bottle bottom can quickly transfer heat to the heat dissipation plate, accelerating the heat dissipation speed. At the same time, cold air is infused into the cooling sandwich layer, which can further accelerate the heat dissipation speed, enabling the high-pressure wet steam to quickly turn into water, thereby realizing the rapid detection of the high-pressure wet steam dryness. Moreover, the entire high-pressure wet steam dryness detection device has a simple and reliable structure, is easy to maintain, has a low cost, a long service life, and is convenient for installation and maintenance, can be mass-produced and applied, and is convenient for market promotion, and is relatively practical.

[0004] Although the above-mentioned scheme has a simple and reliable structure for the entire high-pressure wet steam dryness detection device, the adjustment of the height position of the detection device requires a large number of telescopic rods to cooperate and be locked one by one, and the operation of lifting and positioning the detection device by the equipment is troublesome. Moreover, the cold air is infused into the cooling sandwich layer and is drawn away before contacting the detection bottle for a long time, and the heat dissipation effect of the equipment on the high-pressure wet steam is average. For this reason, we propose an on-line wet steam dryness detection device. Summary of the Invention
