Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic diagram of oil refining by a catalytic device in the related art. As shown in fig. 1, the catalytic apparatus 1 includes a reactor 11 and a regenerator 12, heavy crude oil enters the reactor 11 through a riser 13 to be decomposed under the action of a catalyst at a high temperature to generate light gasoline and diesel oil, and the catalyst forms coke on the surface of the decomposition reaction; the catalyst with coke and gasoline and diesel oil flow into the regenerator 12, and the regenerator 12 burns off the coke on the catalyst, thereby recovering the activity of the catalyst to flow into the reactor 11 again for decomposition. Since catalysts, crude oil, gasoline, and diesel are highly corrosive, the lining of the inner surfaces of the shell of the reactor 11 and the regenerator 12 is easily corroded, thereby causing malfunction.
In the related art, a maintenance worker holds a measuring instrument to detect the shell thicknesses of the reactor 11 and the regenerator 12, and then calculates the corrosion thickness of the lining based on a comparison between the detected shell thickness and the initial shell thickness, thereby determining whether the catalytic device 1 is abnormal.
Although the maintenance personnel can know the corrosion thickness of the catalytic device 1 by holding the measuring instrument for measurement, the manual inspection mode has time interval, and the maintenance personnel cannot know the abnormal condition of the catalytic device 1 in time and can not find and process the fault as soon as possible, so that the catalytic device 1 breaks down and stops production, and economic loss is caused. And when the catalytic apparatus 1 reaches a failure state, the apparatus is damaged seriously, resulting in difficulty in maintenance. In addition, catalytic unit 1's size is big, and maintenance personal need climb catalytic unit 1 and detect, and maintenance personal's intensity of labour is high, has the potential safety hazard.
In view of this, the present application generally provides a monitoring device, in which the monitoring device includes a detection device, a controller, a server and a prompt device, which are connected in sequence, and the detection device is used to monitor the catalytic device 1 in real time without time interval, so that a maintenance worker can timely know about the abnormal condition of the catalytic device 1 according to the prompt information displayed by the prompt device and process the abnormal condition to avoid the shutdown due to the failure of the catalytic device 1, thereby avoiding causing huge economic loss. In addition, because the maintenance personnel can handle the abnormal condition of catalytic unit 1 as early as possible according to the prompt message, can avoid catalytic unit 1 to reach the fault condition and just maintain, the maintenance degree of difficulty is low. And through setting up monitoring device monitoring catalytic unit 1, can avoid the maintenance personal to scramble catalytic unit 1 and carry out manual monitoring, reduced maintenance personal's intensity of labour, alleviateed personnel's potential safety hazard.
Referring to fig. 2, fig. 2 is a schematic view of a monitoring device according to an embodiment of the present invention. As shown in fig. 1 and fig. 2, the monitoring device provided in this embodiment includes a detection device 2, a controller 3, a server 4, and a prompt device, which are connected in sequence; the detection device 2 is used for measuring the temperature of the outer wall of the catalytic device 1; the controller 3 receives the outer wall temperature measured by the detection device 2, calculates the corrosion thickness of the catalytic device 1 according to the outer wall temperature, and uploads the outer wall temperature and the corresponding corrosion thickness of the catalytic device 1 to the server 4, and the server 4 is communicated with the prompt device and used for sending the outer wall temperature and the corresponding corrosion thickness of the catalytic device 1 to the prompt device; the prompting device is used for sending out prompting information when the corrosion thickness reaches the preset thickness.
Since the catalyst and crude oil are reacted in the reactor 11 and the regenerator 12, and the working environment inside the reactor 11 and the regenerator 12 is in a high-temperature, high-pressure and high-corrosion state, in order to ensure that the detection device 2 can work normally, the detection device 2 may be arranged outside the catalytic device 1, specifically, a scaffold may be set up at a position 8m to 15m away from the catalytic device, and the detection device 2 is arranged on the scaffold to perform non-contact temperature detection on the catalytic device 1. For example, the detection device 2 may be an infrared thermal imager, which can accurately measure the temperature of the point to be measured at a longer distance, and has a wide application range. Of course, the detection device 2 may be another example in the related art.
The detection device 2 can measure the temperature of the outer wall of the shell of the reactor 11, and can also measure the temperature of the outer wall of the shell of the regenerator 12. Referring to fig. 3, fig. 3 is a schematic structural diagram of a reactor in a catalytic device according to the related art; the point to be tested may be the inclined tube 111 of the external heat remover in the reactor 11, or may be the cylinder 112 of the external heat remover in the reactor 11. Referring to fig. 4, fig. 4 is a schematic structural diagram of a regenerator in a catalytic device in the related art; the point to be measured can be a semi-regeneration inclined tube upper inclined tube 121 or a semi-regeneration inclined tube lower inclined tube 122 in the regenerator 12. In addition, the point to be tested may also be a circumferential weld 123 on the shell of the regenerator 12. Therefore, since the position of the weld or the melt line etc. on the casing of the regenerator 12 is more easily corroded than the other positions than the semi-regeneration down tube 122 etc. as the point to be measured, the abnormality of the catalytic device 1 can be detected and dealt with earlier by detecting the annular weld 123.
The input end of the controller 3 is electrically connected with the output end of the detection device 2, and is used for receiving the outer wall temperature measured by the detection device 2 and calculating the corrosion thickness of the catalytic device 1 according to the outer wall temperature. Illustratively, the corrosion thickness Δ T of the catalytic device 1 may be calculated by the following formula:
ΔT＝Ts-{(t×F×ρ×E×0.23)÷(C×Tm)}×1000
wherein, the meaning of each parameter in the formula is as follows:
Tsis the initial thickness of the point to be measured in mm. T issConstant, can be obtained by the handbook of the catalytic device 1.
t is the monitoring period in h (hours). t can be 0.5h, 1h or 2h, and the monitoring time period can be set by maintenance personnel according to actual working conditions and experience.
F is the flow of the medium flowing through the point to be measured, and the unit is m3H is used as the reference value. Further, F may be calculated by the formula, i.e., F ═ v × S; v is the flow velocity of the medium flowing through the point to be measured, and is obtained by a flow velocity detector arranged in the point to be measured; s is the flow area of the point to be measured and can be obtained by the manual of the catalytic device 1.
Rho is the density of the medium flowing through the point to be measured and is expressed in Kg/m3ρ is a constant, which can be known from the characteristic parameters of the medium flowing through the point to be measured.
E is the enthalpy value of the medium flowing through the point to be measured, the unit is KJ/Kg, and E is a constant, and can be known according to the characteristic parameters of the medium flowing through the point to be measured.
TmThe average outer wall temperature of a point to be measured in the monitoring time period is in DEG CmDetected by the detection means 2. Illustratively, taking the point to be measured as the semi-regeneration inclined tube upper inclined tube 121, and the monitoring time period T is 1 month, for example, the maximum outer wall temperature of the semi-regeneration inclined tube upper inclined tube 121 in 1 month is 258 ℃, the minimum outer wall temperature is 226 ℃, and then T ismWas 242 ℃.
C is the heat conductivity coefficient of the material of the point to be measured, the unit is W/(m DEG C), C is a constant, and the C can be obtained according to the characteristic parameters of the material of the point to be measured. Taking the material of the regenerator 12 casing as an example, the thermal conductivity of carbon steel at different temperatures is shown in table 1; illustratively, when the outer wall temperature of the regenerator 12 housing is 675 ℃, C is 29.7W/(m.
TABLE 1
It should be understood that the Controller 3 may be a single chip, a Programmable Logic Controller (PLC), or an MCU chip (Microcontroller Unit).
Based on the above, the controller 3 calculates the corrosion thickness Δ T of the catalytic device 1 by a formula, and thus, the calculation process of maintenance personnel is omitted.
The server 4 can be electrically connected with the controller 3 through a cable, can also be connected through wifi, and can also be connected through bluetooth for receiving the outer wall temperature of the point to be measured and the corresponding corrosion thickness transmitted by the controller 3. In an alternative implementation, the server 4 is connected to the controller 3 via wifi to avoid the problem of confusion in the production field caused by cables running in the production field.
Further, a signal repeater can be arranged between the controller 3 and the server 4 and used for bridging signals, and when the server 4 receives weak signals sent by the controller 3, the stability and reliability of signal transmission are guaranteed, so that the influence of the fact that the wifi signals are difficult to cover the whole device on communication due to the fact that the size of the catalytic device 1 is large is reduced.
