Description

Technical Field

[0001] This utility model belongs to the technical field of lubricating oil testing devices, specifically relating to a steam-based antiemulsification device for improving the water separation capability of turbine oil after steam treatment. Background Technology

[0002] When turbine oil is running on a turbine unit, it mainly serves to provide lubrication, cooling, and speed regulation for the turbine main unit and auxiliary turbines. During use, water vapor inevitably enters the lubrication system, causing the oil to emulsify and form an emulsion. If the emulsion cannot be separated in time, the working efficiency of the oil will decrease, affecting the safe and stable operation of the equipment. Therefore, the water separation capacity of turbine oil after water vapor treatment is a particularly important physicochemical performance indicator. Utility Model Content

[0003] The purpose of this invention is to provide a steam demulsification device. This invention aims to combine practical application with simulation of turbine oil operating conditions. It utilizes high-speed steam generated in a steam generator to impact and emulsify the oil, and then tests the water separation capacity of the oil. This provides a means and basis for comparing the water separation capacity of turbine oil after steam treatment.

[0004] To achieve the above objectives, the present invention provides a technical solution: a steam-based demulsification device, comprising a steam generator, a steam inlet pipe, an emulsification generating pipe, a steam outlet pipe, a condensate recovery pipe, and a measuring cylinder; the steam generator, steam inlet pipe, and emulsification generating pipe are connected sequentially. The inlet end of the steam outlet pipe is inserted into the top of the emulsification generating pipe; the outlet end of the steam outlet pipe, the condensate recovery pipe, and the measuring cylinder are connected sequentially.

[0005] In a preferred embodiment, the steam generator is equipped with a resistance wire coil.

[0006] In a preferred embodiment, the steam generator is provided with a protective cover on its outer periphery.

[0007] In a preferred embodiment, the outlet end of the steam inlet pipe is inserted into the bottom of the emulsion generating pipe.

[0008] In a preferred embodiment, the outlet end of the steam inlet pipe has an oblique opening, with the oblique opening facing the center of the bottom of the emulsion generating pipe.

[0009] In a preferred embodiment, the steam generator, steam inlet pipe, and emulsification generation pipe are connected by a glass ball joint.

[0010] In a preferred embodiment, the connection between the steam outlet pipe and the condensate recovery pipe is made by using a glass ball joint.

[0011] This utility model relates to a steam demulsification device. The device simulates the actual operating conditions of a steam turbine. A certain amount of water vapor is uniformly introduced into the oil sample to be tested within a specified time. The high-temperature water vapor heats and stirs the sample to emulsify it. After the water vapor is stopped, the time required to separate a specified volume of oil phase is recorded. The time taken is used to measure the water separation capacity of the oil after steam treatment. Attached Figure Description

[0013] In the diagram: 1 Steam generator, 2 Protective cover, 3 Steam inlet pipe, 4 Emulsion generation pipe, 5 Steam outlet pipe, 6 Condensation recovery pipe, 7 Measuring cylinder, 8 Water injection funnel. Detailed Implementation

[0014] The present invention will be further described below.

[0015] Example 1 like Figure 1 As shown, the steam method (lubricating oil) demulsification device includes a steam generator 1, a protective cover 2, a steam inlet pipe 3, an emulsification generating pipe 4, a steam outlet pipe 5, a condensate recovery pipe 6, a measuring cylinder 7, and a water injection funnel 8.

[0016] The steam generator 1 is the most critical component in the steam-based demulsification apparatus. The steam generator 1 is a single-necked flask equipped with a water-filling funnel 8. The flask consists of a neck, middle section, and bottom. The middle section is a hollow sphere, and the bottom is a hollow cylinder (the cylinder's diameter is smaller than the sphere's). The bottom is heated by an internal resistance wire coil to ensure high heat transfer efficiency. The resistance wire coil has 4-6 turns, ensuring the steam generator produces sufficient steam to meet experimental requirements. The water-filling funnel 8 is located above the neck for timely replenishment of deionized water. The steam generator 1 is made of high-temperature resistant glass, has a volume of 2000-2500 mL, a maximum heating power exceeding 1000 W, and stepless adjustment of the heating power to ensure a steam generation rate of over 15 g / min.

[0017] A protective cover 2 (enclosing the middle and bottom) is installed around the steam generator 1. The protective cover 2 is composed of steel and transparent plexiglass. Since the glass steam generator 1 poses a risk of glass shattering and boiling water leakage during the high-temperature heating process of the resistance wire, the protective cover 2 serves to prevent burns.

[0018] Steam generator 1, steam inlet pipe 3 (inner diameter 6-8mm) and emulsion generating pipe 4 are connected in sequence, all using glass ball joints to facilitate the connection of various glass components during the test.

[0019] The inner diameter of the emulsion generating tube 4 is 45mm and the height is 430mm. It is marked with a 100mL scale line. There are length scale lines above and below the scale line, with a range of 6cm and the lowest scale line is 1mm. The lower end of the gas delivery tube inside the emulsion generating tube 4 is beveled, and the bevel is oriented towards the center of the bottom of the emulsion generating tube.

[0020] The steam outlet pipe 5 is placed above the emulsion generating pipe 4 with a straight connector. The inner diameter of the outlet pipe is 6-8mm, and it is connected to the condensate recovery pipe 6 with a ball connector.

[0021] The condensate recovery tube 6 is a spherical condensate tube. Inside the condensate recovery tube 6, there are 4-6 interconnected glass spheres, and the temperature of the condensate is 10-15℃.

[0022] The graduated cylinder has a measuring range of 250 mL and a minimum graduation of 5 mL.

[0023] Test case The apparatus of Example 1 was used for testing. 100 mL of the oil to be tested was placed at the bottom of the emulsification generating tube 4. Deionized water was added to the steam generator 1, and the resistance wire coil of the steam generator 1 was started to heat and generate steam. The steam entered the bottom of the oil to be tested through the steam inlet pipe 3 and the timing was started. The steam coming out of the inlet pipe 3 impacted and agitated the oil to be tested at high speed in the emulsification generating tube 4, heating and emulsifying the oil. The steam after passing through the oil entered the condensation recovery pipe 6 through the steam outlet pipe 5 and condensed to form room temperature liquid water, which was collected in the measuring cylinder 7. After 20 minutes (the volume of condensed water collected should be 205±5 mL), the steam supply was stopped and the timing was restarted. The time required for the oil phase with a height of 55 mm (volume 87.5 mL) to separate in the emulsification generating tube 4 was recorded. The length of this time was used to measure the water separation ability of the oil after steam treatment.

[0024] This utility model device has a simple and clear design, high reliability, and good safety. It can closely simulate actual operating conditions to generate high-speed and stable steam to emulsify oil products. The water separation capacity of the oil products is easy to detect, providing a means and basis for comparing the water separation capacity of oil products.
