Description

Technical Field

[0001] The utility model belongs to the technical field of separators, and in particular relates to a multi-stage anti-scaling steam-water separator. Background Art

[0002] During the mining process, natural gas and hydrogen sulfide in the formation penetrate into the brine produced through the formation fissures. The temperature of the brine in the dissolution cavity is generally around 40-55°C. If the brine is not treated, a large amount of HO4 and H2S will be emitted into the atmosphere, affecting the environment. During the transportation process, they enter the pipeline and affect the transportation efficiency. Due to the existence of temperature difference and pressure difference, when the brine is collected on the ground, it creates favorable conditions for natural separation. However, the pH value of the brine is 6-6.5, which is weakly acidic. Since the use of light salt water injection wells to extract brine, the pH value of the brine is 8-10, which is alkaline. Alkaline brine is easy to scale. Therefore, in the past use process, if a conventional separation structure is used, the separation efficiency is low and the hourly processing capacity is not very ideal. In particular, after the injection hole of the liquid distributor is blocked by scaling, it must be stopped for pickling before it can be resumed. In addition, a large amount of oxalic acid is used in the pickling process, which not only affects the normal production of brine, but also the solution treatment after pickling is also very troublesome. Therefore, it is necessary to solve three problems: hourly processing capacity, gas separation capacity, anti-scaling and non-stop production.

[0003] At present, there is no such steam-water separator that can be continuously produced with multi-stage sharing and anti-scaling in the well salt industry. Generally, the water inlet plate uses a shower-like spray to form a violent aeration process on the separation plate to release the gas from the liquid. However, due to the high pH value of our company's brine, the sieve holes of the shower head are easily blocked. In view of this situation, the top of the spray device is not covered and is made into an open shape. If the sieve holes are blocked, the water can overflow from the top to meet the separation process requirements. Utility Model Content
