Referring to fig. 2, fig. 2 is a first embodiment of a static device corrosion monitoring method according to the present invention, where the static device includes a housing, an outer wall of the housing is divided into a plurality of monitoring areas, each monitoring area is provided with a temperature sensor, and the static device corrosion monitoring method includes the following steps:
it should be noted that in this embodiment, the static equipment may be static equipment in the oil refining and chemical industry, such as a reactor, a regenerator, an air cooler, and the like. At present, corrosion monitoring of static equipment in the petrochemical industry mainly depends on manual inspection, and some problems of the static equipment are detected by a handheld infrared thermometer, but the manual detection has potential safety hazards, only a specific area can be detected, the detection of the whole device cannot be realized, and the inaccurate and inconvenient measurement is caused. In this embodiment, the temperature sensor is used to collect the temperature of the casing of the static device to monitor the corrosion degree of the casing of the static device, and since the medium inside the static device is generally high temperature, high pressure and high corrosion, the detection device cannot be directly arranged inside to monitor the corrosion parameters of the static device, and only the temperature sensor can be arranged at the pipeline opening of the static device and/or on the outer wall of the static device to perform indirect measurement. The medium in the static equipment can corrode the shell of the static equipment, and if the corrosion thickness is larger, namely the residual thickness of the shell is smaller, the temperature value detected in the corresponding area of the outer wall of the static equipment is higher. In order to more fully understand the corrosion condition of the static equipment wall, a plurality of temperature sensors are required to be arranged in different areas on the outer wall of the static equipment to acquire temperature field data of each area, so that the corrosion position of the outer wall of the static equipment is accurately determined according to position information in the temperature field data, and the corrosion degree of the outer wall of the static equipment is determined according to temperature value information in the temperature field data.
Step S10, determining the surface temperature corresponding to each monitoring area according to the detection data of the temperature sensor;
the monitoring areas are distributed at different positions of static equipment, such as an upper inclined pipe of a semi-regeneration inclined pipe, a lower inclined pipe of the semi-regeneration inclined pipe, a thermocouple of a two-second-northwest corner combustion oil nozzle, an annular welding seam of a transition section, an expansion joint of the regeneration inclined pipe, the upper part of a two-second-southwest side manhole and the like. The temperature sensor is a device capable of acquiring temperature field data, the position information is coordinate information such as an X coordinate and a Y coordinate, and the temperature value is a temperature value corresponding to the coordinate information.

the surface temperature may be temperature field data. The structural parameters include the original thickness of the housing, the thermal conductivity of the material of the housing, and the like. The medium stored in the static equipment can be high-temperature, high-pressure and high-corrosion media, such as oil gas, flue gas, catalysts and the like, the high temperature can reach 720 ℃, the high pressure can reach 0.35MPa, and the medium parameters comprise internal medium flow, medium density, medium enthalpy and the like. The starting up running time of the equipment is the time from the beginning of putting into operation to the current time of the static equipment. Alternatively, the original thickness of the shell may be 32 mm, the material may be a carbon steel material, and the thermal conductivity of the material may be 29.7W/(m.
And step S30, determining the corrosion thickness corresponding to each monitoring area according to the surface temperature, the structural parameters of the shell, the medium parameters stored in the static equipment and the startup running time of the static equipment.
It can be understood that the more the static equipment casing is corroded, the thinner the remaining thickness of the casing is, and the higher the temperature value detected by the temperature sensor arranged on the outer wall of the static equipment casing is, so that the corrosion thickness of each monitored area can be determined according to the surface temperature of the static equipment casing.
Optionally, when the corrosion thickness corresponding to at least one of the monitoring regions is greater than or equal to a preset thickness, outputting corrosion abnormality early warning information.
The preset thickness can be set according to the actual condition of the static equipment. The early warning information can be prompted in the forms of characters, audio, warning lamps and the like so as to prompt a user to take corresponding measures according to the current corrosion condition.
In the technical scheme provided by this embodiment, temperature sensors are respectively arranged in a plurality of monitoring areas on the outer wall of a static equipment shell, and a static equipment corrosion monitoring device determines the surface temperature corresponding to each monitoring area according to the detection data of the temperature sensors; acquiring the structural parameters of the shell, the medium parameters stored in the static equipment and the starting-up running time of the static equipment; and determining the corrosion thickness corresponding to each monitoring area according to the surface temperature, the structural parameters of the shell, the medium parameters stored in the static equipment and the starting operation time of the static equipment. Therefore, the temperature sensor is directly arranged on the outer wall of the static equipment shell to acquire surface temperature data, the corrosion thickness of the static equipment shell is calculated according to the surface temperature and the prestored static equipment parameters, and when at least one preset corrosion thickness exists in the corrosion thickness of each monitoring area, abnormal corrosion early warning information is output, so that the convenience of monitoring the corrosion of the static equipment is improved.
Referring to fig. 3, fig. 3 is a second embodiment of the method for monitoring corrosion of static equipment according to the present invention, and based on the first embodiment, before the step S30, the method further includes:
step S31, obtaining a pre-stored calculation weight;
the step S30 includes:
and step S32, determining the corrosion thickness corresponding to each monitoring area according to the pre-stored calculation weight, the surface temperature, the structural parameters of the shell, the medium parameters stored in the static equipment and the startup operation time of the static equipment.
Optionally, processing the surface temperature, the structural parameters of the casing, the medium parameters stored in the static equipment and the startup running time of the static equipment according to the pre-stored calculation weight to obtain corrosion thicknesses corresponding to the monitoring regions through a preset formula, wherein the preset formula is Δ T ═ Ts- { (T × F × ρ × E ×/× /) β, the Δ T is the corrosion thickness of the outer wall of the static equipment, the Ts is the original thickness of the outer wall of the casing of the static equipment, the T is the startup running time of the static equipment, the F is the flow rate of the medium inside the static equipment, the ρ is the density of the medium inside the static equipment, the E is the enthalpy value of the medium inside the static equipment, the C is the heat conductivity coefficient of the material of the outer wall of the static equipment, and the Tm is the surface temperature of the outer wall of the static equipment. The alpha and beta are preset weighted values.
Alternatively, the preset weight α may be 0.23, and the preset weight β may be 100. The preset weighted value is extracted based on historical data in preset historical duration, is a corrected value, and is obtained after big data learning is carried out on the corrected value in the face of different static equipment.

In the technical scheme provided by the embodiment, the static equipment corrosion monitoring device acquires the pre-stored calculation weight; and determining the corrosion thickness corresponding to each monitoring area according to the pre-stored calculation weight, the surface temperature, the structural parameters of the shell, the medium parameters stored in the static equipment and the startup running time of the static equipment. Therefore, the corrosion thickness of the static equipment shell is calculated by integrating the structural parameters of the static equipment shell, the medium parameters in the static equipment, the starting running time of the static equipment, the surface temperature of the static equipment and the preset weighting value, so that the accuracy of monitoring the corrosion of the static equipment is improved.
Referring to fig. 4, fig. 4 is a third embodiment of the method for monitoring corrosion of static equipment according to the present invention, and based on the first or second embodiment, after step S30, the method further includes:
step S40, determining the temperature change rate in the historical preset time;
optionally, the step S40 includes: acquiring surface temperature data within a historical preset time;
and determining the historical temperature change rate according to the surface temperature data in the historical preset time and the historical preset time.
The static equipment corrosion monitoring data in the historical preset time length can be static equipment corrosion monitoring data in the previous day or the previous month or the previous year. And the historical temperature change rate is the temperature change value in the historical preset time length divided by the historical preset time length.
Step S50, determining a reference corrosion rate according to the historical temperature change rate and the mapping relation between the temperature and the corrosion thickness;
optionally, before the step S50, the method further includes: acquiring the surface temperature corresponding to each monitoring area and the corrosion thickness corresponding to the surface temperature;
and determining a mapping relation between the surface temperature and the corrosion thickness corresponding to the surface temperature, wherein the higher the surface temperature is, the larger the corrosion thickness is, namely, the positive correlation is formed between the surface temperature and the corrosion thickness.
For example, after the static equipment surface temperature data is acquired and the corresponding corrosion thickness is calculated according to the surface temperature, the mapping relation between the surface temperature and the corrosion thickness corresponding to the surface temperature is determined and stored in a correlated manner, and the static equipment surface temperature acquired within one month and the calculated corrosion thickness data are recorded. Because the surface temperature data of the static equipment and the corrosion thickness are stored in advance in a correlated manner, the corresponding corrosion thickness relation can be known by acquiring the surface temperature data, namely, the shell corrosion thickness of the static equipment can be early warned according to the surface temperature change rate of the static equipment, wherein the faster the surface temperature change rate is, the faster the corrosion rate is.
And step S60, carrying out corrosion early warning on the static equipment according to the reference corrosion rate.
Optionally, the step S60 includes: acquiring real-time surface temperature and determining real-time temperature change rate;
determining a real-time corrosion rate according to the real-time temperature change rate and the mapping relation between the temperature and the corrosion thickness;
and outputting corrosion abnormity prompt information when the difference value between the real-time corrosion rate and the reference corrosion rate is greater than a preset threshold value.
The preset threshold value can be set according to the actual condition of the static equipment, the corrosion rate of the fluid medium stored in the static equipment under the condition that the reference corrosion rate is generally the corrosion rate of the static equipment by the shell of the static equipment along with the lapse of the running time of the static equipment under the normal condition, and under the normal condition, the real-time corrosion rate of the static equipment generally has a small difference with the reference corrosion rate, so that the real-time corrosion rate is compared with the reference corrosion rate, and if the difference between the real-time corrosion rate and the reference corrosion rate exceeds the preset threshold value, the corrosion rate of the fluid medium stored in the static equipment to the static equipment is abnormal, and corresponding warning needs to be carried out.
In the technical scheme provided by the embodiment, the static equipment corrosion monitoring device determines the temperature change rate within a historical preset time; determining a reference corrosion rate according to the historical temperature change rate and the mapping relation between the temperature and the corrosion thickness; and carrying out corrosion early warning on the static equipment according to the reference corrosion rate. Therefore, the corrosion condition of the static equipment can be predicted by utilizing the surface temperature change rate of the static equipment within the historical preset time and the mapping relation between the temperature and the corrosion thickness, and the mapping relation between the temperature and the corrosion thickness can be stored in the device in advance, so that the static equipment corrosion monitoring device can directly perform early warning on the corrosion condition of the static equipment according to the real-time temperature change rate and the temperature change rate of the static equipment within the historical preset time, and the convenience of static equipment corrosion monitoring is improved.

and step S52, determining the corrosion rate according to the reference temperature change curve, wherein the larger the slope of the reference temperature change curve is, the higher the corrosion rate is.
Alternatively, referring to fig. 6, fig. 6 is a schematic diagram of a temperature variation curve in the static equipment corrosion monitoring method according to the present invention. The method comprises the steps of drawing surface temperature data acquired within a preset historical time length in a coordinate graph according to a specific time interval, and fitting the surface temperature data with a smooth reference temperature change curve according to a preset algorithm, wherein a curve slope corresponding to a curve section of the reference temperature change curve between time points is the corrosion rate of the static equipment shell at each specific time interval, and the larger the curve slope is, the larger the corrosion rate of the static equipment shell is.
