Description
Technical Field
The utility model belongs to the technical field of production devices of coking production and chemical products, and particularly relates to a device for measuring interfaces of liquids with different specific gravities.
Background
The tar ammonia water mixture generated in the coking process needs to enter a mechanical clarifying tank for separation. Due to different densities, the mixture after standing in the mechanical clarifying tank is divided into three layers from top to bottom: ammonia layer, tar layer, and tar residue layer. The ammonia water is discharged into the ammonia water tank through the upper layer pipeline, and the tar at the middle layer is pressed into the tar tank through the lower layer pipeline. The lower layer tar residue is taken out through the scraper and enters the residue car. In the actual production, the interface of tar and ammonia water is not easy to observe, which results in incomplete separation of tar and ammonia water, i.e. the tar contains a large amount of ammonia water and the ammonia water contains a large amount of tar.
In the prior art, a floating ball type magnetic telescopic interface instrument with specific gravity between two kinds of liquid is adopted to measure a liquid interface, or the temperature of the outer wall of a container is measured through the specific heat difference of the two kinds of liquid, and the liquid interface is judged through the temperature difference. However, the magnetic telescopic interface instrument has high manufacturing cost, difficult maintenance, large volume and difficult installation and transportation. The error of the method for measuring the temperature of the outer wall is large, and the online continuous monitoring can not be realized.

FIG. 1 is a schematic structural view of the device for measuring the interface of liquids with different specific gravities, which is provided by the utility model.
Detailed Description
The utility model aims to provide a device capable of measuring the interface of two mutually insoluble liquids with different specific gravities in the same container.
As shown in FIG. 1, the structure of the device for measuring the interface of the liquid with different specific gravities provided by the utility model is shown schematically (6 in FIG. 1 represents the interface, the liquid with low specific gravity is shown above the interface, and the liquid with high specific gravity is shown below the interface), which comprises a mechanical clarification tank 5, a pipeline 1, a valve 2 (which can be a ball valve) and a pressure gauge 3; wherein the bottom of the side of the mechanized settling tank 5 is provided with a hole (such as DN30 hole), one end of the pipeline 1 is fixedly arranged at the hole, for example, the hole is fixedly arranged in a welding way, the pressure gauge 3 is arranged at the other end of the pipeline 1, a pressure detection probe of the pressure gauge 3 is inserted into the pipeline 1, and the valve 2 is arranged on the pipeline 1. In the embodiment shown in fig. 1, the pipeline 1 comprises a first pipeline 11 and a second pipeline 12, wherein one end of the first pipeline 11 is arranged at the hole, the other end of the first pipeline is connected with one side of the valve 2 through a flange, the other side of the valve 2 is connected with one end of the second pipeline 12 through another flange, the other end of the second pipeline 12 is provided with the pressure gauge 3, the pressure gauge 3 can measure the pressure of the liquid at the bottom of the mechanical clarification tank 5 and display the pressure value, and the interface of the liquid with different specific gravities in the mechanical clarification tank 5 can be calculated by knowing the specific gravities of two different liquids. For example, it can be known from the liquid pressure calculation formula (pascal's law) P ═ ρ gh that the liquid level in the tank is at a constant height, the pressure is directly correlated with the liquid density, and if the density of liquid a is 1.0, the density of liquid B is 1.2, and the distance from the opening to the top of the liquid level is 4m, if the liquid a is present in the tank, the pressure is measured to be 4.0KPa, and if the mixture of liquid a and liquid B is present in the tank, the pressure is measured to be 4.5KPa, then a linear equation set of two elements, i.e., x + y is 4, x +1.2y is 4.5, and by calculation, x is 1.5 and y is 2.5, it can be known that the interface of liquid A, B is 2.5m above the opening.
When the device for measuring the interface of the liquid with different specific gravities provided by the utility model is used, the following steps can be included:
A. the density ratio of a liquid having a small specific gravity to a liquid having a large specific gravity is known as h: j.
B. The vertical distance a from the liquid level in the mechanical clarification tank 5 to the central position of the pipeline 1 of the device is measured.
C. If the liquid with small specific gravity is totally filled in the mechanical clarifying tank 5, a pressure value P1 can be measured by using the pressure gauge 3 of the device.
D. If the mixture of the liquid A with low specific gravity and the liquid B with high specific gravity is in the mechanical clarifying tank 5, a pressure value P2 can be measured by the pressure gauge 3 of the device.
E. If the height from the upper surface of the liquid having a low specific gravity to the interface between the two liquids is x and the height from the interface to the center of the pipe 1 welded to the mechanical clarifier 5 is y, a system of linear equations with two equations, i.e., x + y ═ a and h · x + j · y ═ P2, can be obtained from the above results. Solving the above system of equations yields the values of x and y, i.e., the respective heights of the two liquids within the tank. The height of the interface of the two liquids above the central position of the pipe 1 welded to the mechanized settler 5 can thus be obtained.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
