Description

Technical Field

[0001] This invention relates to the field of risk monitoring systems for chemical equipment, and in particular to a risk monitoring system and method for chemical equipment. Background Technology

[0002] Chemical equipment refers to the tools used in chemical plants to achieve chemical production. The normal operation of the chemical production process, as well as the control and assurance of product quality and output, are inseparable from the adaptation and normal operation of various chemical equipment.

[0003] In the existing technology, in order to ensure the normal operation of the chemical industry, it is often necessary to conduct inspections of chemical workshops, including lines and pipelines. For reaction equipment such as reactors and separators, safety inspections are usually carried out by pressure testing or vibration testing. However, such inspections are more focused on safety. In actual production, the efficiency of chemical reactions has already begun to decline in the early stages of chemical equipment damage. The existing technology lacks monitoring equipment that can detect problems in the early stages of chemical equipment damage. Summary of the Invention

[0004] Based on this, the present invention provides a risk monitoring system and method for chemical equipment, which can measure the reaction environment and reaction rate inside the chemical equipment online, thereby realizing the measurement of the safety of the chemical equipment and improving the reaction rate inside the chemical equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A risk monitoring system for chemical equipment includes a monitoring module and a comparison module. The monitoring module includes at least a temperature monitoring module, a pH value monitoring module, a product concentration monitoring module, and a reactant concentration monitoring module. Several groups of monitoring modules are distributed at least three intervals along the height of the chemical equipment. The risk monitoring system also includes at least one set of level gauges. At least three monitoring modules are provided at each height position of the chemical equipment. The comparison module compares the actual monitoring value of the monitoring module with the monitoring value of the monitoring module under ideal conditions.

[0007] By monitoring the internal temperature, pH value, liquid level, and reaction rate of chemical equipment, it is possible to monitor the internal environment and reaction rate of chemical equipment. Multiple monitoring modules are set up along the height of the chemical equipment to achieve more systematic and comprehensive monitoring of the internal structure of the chemical equipment, thereby improving the reliability of the monitoring results.

[0008] Preferably, the system also includes an adjustment module, which comprises a heating device, an acid / base addition component, and a reactant addition component. Based on the comparison results from the comparison module, the adjustment module can automatically adjust parameters such as temperature, pH level, and reactant concentration, thereby increasing the reaction rate within the chemical equipment.

[0009] Preferably, the monitoring modules are arranged in a grid pattern on the inner wall of the chemical equipment. This forms multiple monitoring points in a grid pattern, improving the reliability of the monitoring results.

[0010] Preferably, the monitoring module is equipped with a wireless transmission module that transmits data from the monitoring module to the comparison module for storage and comparison. The monitoring module uses wireless transmission, eliminating the need for wiring to connect the inside and outside of the chemical equipment, thus ensuring the reliability of the internal reaction environment.

[0011] An installation sleeve is installed inside the reactor and is coaxially mounted on the side wall of the reactor. The monitoring module is snapped onto the inner surface of the installation sleeve.

[0012] Preferably, the inner circumferential surface of the mounting sleeve is provided with a connecting hole. The inner end of the connecting hole has an inner conical section with a smaller outer end and a larger inner end, and the outer end has an outer conical section with a smaller inner end and a larger outer end. The monitoring module is provided with a connector. The root of the connector is provided with a root conical section that mates with the conical surface of the outer conical section. The free end of the connector is provided with several elastic flaps distributed circumferentially along the connector. The outer surface of the free end of the elastic flaps is provided with a hook that mates with the conical surface of the inner conical section. The hook hooks onto the inner conical section, so that the root conical section and the outer conical section are sealed together. This design prevents the connector from easily falling off, ensures a reliable seal between the connector and the connecting hole, and prevents shaking.

[0013] Preferably, the inner conical surface section is provided with several annular teeth distributed axially along the conical surface section with the tooth tips facing inward. Adjacent annular teeth form barbed grooves. The surface of the hook head that mates with the inner conical surface section is provided with several barbed teeth facing outward from the connecting hole. The barbed teeth hook into the barbed grooves to prevent the connector head from exiting the connecting hole. This improves the reliability of the seal. Because, in order to achieve a seal, the hook head and the inner end of the connecting hole are in a conical fit with a smaller outer end and a larger inner end, this fit can cause disengagement. This technical solution solves the problem of easy disengagement.

[0014] Preferably, a gap is provided between the monitoring module and the mounting sleeve, surrounding the connector. An elastic sealing ring is provided within this gap to seal the monitoring module and the mounting sleeve together. The radially outer end of the elastic sealing ring extends to the periphery of the monitoring module. This design allows for reliable sealing by increasing the insertion depth of the connector, compensating for wear when there is poor fit accuracy or wear occurs between the outer and root conical sections. Furthermore, the elastic sealing ring prevents objects from entering the gap, thus avoiding cleaning difficulties.

[0015] Preferably, the mounting sleeve is an elastic structure, and a sloped transition section is provided between the side wall and bottom wall of the reactor. The lower end of the mounting sleeve is supported at the connection between the sloped transition section and the side wall of the reactor. The mounting sleeve, which integrates the detection module, is installed into the reactor. During installation, the mounting sleeve is first placed inwards to facilitate placement into the reactor and lowered to the set position. Then, it springs open and abuts against the inner circumferential surface of the reactor.

[0016] Preferably, the monitoring module includes a wireless transmission module that transmits the data detected by the monitoring module to a comparison module for storage and comparison. The outer circumference of the mounting sleeve has mounting holes that correspond one-to-one with and communicate with the connecting holes. The wireless transmission module is located within one of the mounting holes. The end of the mounting hole furthest from the connecting hole is sealed with an elastic sealing plug. The connector is a tubular structure, and the wire of the monitoring module enters from the connector and passes through the mounting hole to connect with the wireless transmission module. The mounting sleeve is a heat-insulating structure. This design makes the wireless transmission module less susceptible to the temperature inside the reactor, improving transmission reliability.

[0017] A method based on the aforementioned risk monitoring system for chemical equipment includes the following steps: A. The chemical equipment is operating normally. B. Compare the liquid level monitoring value inside the chemical equipment; if the liquid level drops too quickly, the chemical equipment needs to be shut down for inspection and repair to check for leaks; if the liquid level monitoring value is normal compared with the ideal state detection value, proceed to step C. C. Compare the rate of change in the concentration of the reactants; If the rate of change of reactant concentration is normal, the equipment is considered to be functioning properly, and step B is repeated. If the rate of change in reactant concentration is slow, it is determined to be an abnormal reaction, and the following steps are performed in sequence: C1. Compare the reactant concentration. If the concentration is low, add reactants to the chemical equipment through the reactant addition component. If the concentration is normal, proceed to step C2. C2. Compare the temperature environment inside the chemical equipment. If the temperature is low, raise the temperature using a heating device. If the temperature is normal, proceed to step C3. C3. Compare the pH value of the chemical equipment. If the pH value is abnormal, correct it using the acid-base additive component. If the pH value is normal, proceed to step D. D. Compare the temperature monitoring values ​​of different monitoring modules; If, in step D, the temperature monitoring values ​​of each monitoring module exceed the fluctuation threshold, the chemical equipment is judged to be abnormal and shut down for maintenance. If the temperature monitoring values ​​of each monitoring module are within the fluctuation threshold range, the chemical equipment is judged to be normal, and step B is repeated.

[0018] The method of this application first monitors the liquid level and the rate of liquid level reduction inside the chemical equipment to determine the leakage situation of the chemical equipment, which corresponds to the most important detection content of chemical equipment safety. Then, it monitors the overall concentration of reactants, internal temperature of chemical equipment and pH value. When these are all normal, it uses multiple monitoring modules set up at multiple points to achieve lateral comparative detection of local areas of chemical equipment. In step D, when stress deformation occurs inside the chemical equipment, the reaction rate of reactants and temperature environment will change relative to other normal areas. Lateral comparison can quickly find the problem location. At this time, the chemical equipment as a whole is in normal working condition, but the actual equipment has already shown a risk point. The relevant location can be detected intuitively and quickly through this monitoring system and method.

[0019] Preferably, in step D, the temperature monitoring values ​​of each monitoring module are set to a fluctuation threshold of 5 to 10 degrees Celsius. When the temperature monitoring values ​​of any monitoring module exceed the fluctuation threshold, a risk point is established for the equipment, and maintenance is required.

[0020] Preferably, the chemical equipment is a reaction vessel. The monitoring module is located inside the reaction vessel, the comparison module is located outside the reaction vessel, and the adjustment module is located on the wall of the reaction vessel. The comparison module receives and processes signals from the monitoring module wirelessly. The division of labor and placement of each module are reasonable.

[0021] Preferably, the upper end of the reactor is detachably equipped with an end cap, allowing the monitoring module to be inserted into the reactor from the top and then snapped in place. This enables the monitoring module to be easily disassembled and reassembled relative to the chemical equipment.

[0022] Preferably, the monitoring module includes a ring-shaped mounting sleeve, within which a temperature monitoring module, a pH monitoring module, a product concentration monitoring module, a level gauge, and a reactant concentration monitoring module are embedded. The mounting sleeve is used for the overall installation of the monitoring module within the chemical equipment, and also provides protection for the monitoring module, facilitating the concealment of wiring.

[0023] The present invention has the following beneficial effects: it can measure the reaction environment and reaction rate inside chemical equipment online, thereby realizing the measurement of the safety of chemical equipment and improving the reaction rate inside chemical equipment.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention. Example 1

[0032] This application proposes a risk monitoring system for chemical equipment, such as... Figure 1 and Figure 2As shown, the system includes a monitoring module 1 and a comparison module 2. The monitoring module 1 includes at least a temperature monitoring module 3, a pH monitoring module 4, a product concentration monitoring module 5, and a reactant concentration monitoring module 6. Several groups of monitoring modules 1 are distributed at least three intervals along the height of the chemical equipment. At least three monitoring modules 1 are located at each height position of the chemical equipment. The risk monitoring system also includes at least one set of level gauges 7 to monitor the liquid level within the chemical equipment. The comparison module 2 compares the actual monitoring value of the monitoring modules 1 with the monitoring value under ideal conditions. Specifically, in this embodiment, the monitoring modules 1 are set at the top, middle, and bottom along the height of the chemical equipment, with six monitoring modules 1 at each height position. Each monitoring module 1 includes a temperature monitoring module 3, a pH monitoring module 4, a product concentration monitoring module 5, and a reactant concentration monitoring module 6. The temperature monitoring module 3, pH monitoring module 4, product concentration monitoring module 5, and reactant concentration monitoring module 6 employ corresponding functional detection sensors. The level gauges 7 are glass tube level gauges. By monitoring the internal temperature, pH value, liquid level and reaction rate of chemical equipment, it is possible to monitor the internal environment and internal reaction rate of chemical equipment. The monitoring module 1 has multiple sets set in the height direction of chemical equipment, so as to realize a more systematic and comprehensive monitoring of the internal environment of chemical equipment and improve the reliability of monitoring results.

[0033] The risk monitoring system disclosed in this embodiment also includes an adjustment module, which comprises a heating device, an acid-base addition component, and a reactant addition component. Based on the comparison results of the comparison module 2, the adjustment module can automatically adjust environmental parameters such as temperature, pH value, and reactant concentration, thereby improving the reaction rate inside the chemical equipment. The monitoring modules 1 are arranged in a matrix on the inner wall of the chemical equipment to form a grid. The multiple monitoring points forming the grid improve the reliability of the monitoring results and can form a monitoring layout with an approximate coordinate system. The monitoring position of a single monitoring module 1 can help determine the fault point inside the chemical equipment. The data from the monitoring modules 1 is wirelessly transmitted to the comparison module 2 for storage and comparison. That is, the monitoring module is equipped with a wireless transmission module 20 that transmits the data from the monitoring modules to the comparison module for storage and comparison. The monitoring modules 1 use wireless transmission, eliminating the need for wiring to connect the inside and outside of the chemical equipment, thus ensuring the reliability of the reaction environment inside the chemical equipment.

[0034] For example, in this embodiment, the chemical equipment is a reactor 9. The monitoring module is located inside the reactor 9, the comparison module 2 is located outside the reactor 9, and the adjustment module is located on the wall of the reactor 9. The comparison module 2 receives and processes signals from the monitoring module wirelessly, and the division of labor and placement of each module are reasonable. A heating coil 10 is installed on the circumferential side wall of the reactor 9 to form a heating device that can heat the internal temperature of the reactor 9. A feed port 11, an acid port 12, and an alkali port 13 are provided on the upper side of the reactor 9. The feed port 11 is connected to the feed pump 14 and the material tank through a pipe to form a reactant addition component. The acid port 12 is connected to the acid pump 15 and the acid tank through a pipe, and the alkali port 13 is connected to the alkali pump 16 and the alkali tank through a pipe to form an acid-alkali addition component. The heating coil 10, the feed pump 14, the acid pump 15, and the alkali pump 16 are controlled by the control circuit of the comparison module 2.

[0035] Monitoring module 1 includes a temperature monitoring module 3, a pH monitoring module 4, a product concentration monitoring module 5, a level gauge 7, and a reactant concentration monitoring module 6. An installation sleeve 8 is inserted inside the reactor and coaxially mounted on the side wall of the reactor. The monitoring modules are snapped onto the inner surface of the installation sleeve. The installation sleeve is an elastic structure, and a sloped transition section 18 is provided between the side wall and bottom wall of the reactor. The lower end of the installation sleeve is supported at the connection between the sloped transition section and the side wall of the reactor.

[0036] The monitoring module 1 is embedded within the mounting sleeve 8. The mounting sleeve 8 is used for the overall installation of the monitoring module 1 within the chemical equipment, providing protection for the monitoring module 1 and facilitating the concealment of wiring. A locking block can be installed on the outer side of the mounting sleeve 8, and a locking groove is provided inside the reactor 9. After the mounting sleeve 8 extends into the reactor 9, the locking block and the locking groove engage to form a circumferential rotation limit. Furthermore, a detachable end cap 17 is provided at the upper end of the reactor 9, allowing the monitoring module 1 to be inserted from the upper end of the reactor 9 and then locked in place. The end cap 17 and the bottom of the reactor 9 form a longitudinal locking mechanism against the mounting sleeve 8, thereby enabling the overall assembly and disassembly of the monitoring module 1 relative to the chemical equipment, and facilitating easy assembly and disassembly.

[0037] The monitoring module is snapped onto the inner surface of the mounting sleeve. The inner circumferential surface of the mounting sleeve has a connecting hole 19. The inner end of the connecting hole has an inner conical section 21 (smaller at the outer end and larger at the inner end), and the outer end has an outer conical section 22 (smaller at the inner end and larger at the outer end). The monitoring module has a connector 23. The root of the connector has a root conical section 24 that mates with the conical surface of the outer conical section. The free end of the connector has several elastic flaps 25 distributed circumferentially. The outer surface of the free end of the elastic flaps has hooks 26 that mate with the conical surface of the inner conical section. The hooks hook onto the inner conical section, sealing the root conical section and the outer conical section together. The inner conical section has several annular teeth 27 with their tips facing inwards and distributed axially along the conical section. Adjacent annular teeth form barbed grooves. The surface of the hook that mates with the inner conical section has several barbed teeth 28 with their tips facing outwards from the connecting hole. The barbed teeth hook into the barbed grooves, preventing the connector from exiting the connecting hole. A gap 29 surrounds the connector between the monitoring module and the mounting sleeve. An elastic sealing ring 30 is installed within the gap to seal the monitoring module and the mounting sleeve together. The radially outer end of the elastic sealing ring extends to the periphery of the monitoring module. The outer circumferential surface of the mounting sleeve has mounting holes 31 that correspond to and communicate with the connection holes. The wireless transmission module 20 is located within the mounting holes. The end of the mounting hole furthest from the connection hole is sealed by an elastic sealing plug 32. The connector has a tubular structure. The wire 33 of the monitoring module enters from the connector and passes through the mounting hole to connect with the wireless transmission module. The mounting sleeve has a heat-insulating structure.

[0038] A method based on the aforementioned risk monitoring system for chemical equipment, such as Figure 3 As shown, it includes the following steps: A. The chemical equipment is operating normally. B. Compare the liquid level monitoring value inside the chemical equipment; if the liquid level drops at a rate exceeding the set range, the chemical equipment must be shut down for inspection and repair to check for leaks; if the liquid level monitoring value is normal compared to the ideal state detection value, proceed to step C. C. Compare the rate of change in the concentration of the reactants; If the rate of change of reactant concentration is normal, the equipment is considered to be functioning properly, and step B is repeated. If the rate of change in reactant concentration is slow, it is determined to be an abnormal reaction, and the following steps are performed in sequence: C1. Compare the reactant concentration. If the concentration is low, add reactants to the chemical equipment through the reactant addition component. If the concentration is normal, proceed to step C2. C2. Compare the temperature environment inside the chemical equipment. If the temperature is low, raise the temperature using a heating device. If the temperature is normal, proceed to step C3. C3. Compare the pH value of the chemical equipment. If the pH value is abnormal, correct it using the acid-base additive component. If the pH value is normal, proceed to step D. D. Compare the temperature monitoring values ​​of different monitoring modules 1; If, in step D, the temperature monitoring values ​​of each monitoring module 1 exceed the fluctuation threshold, the chemical equipment is judged to be abnormal and shut down for maintenance. If the temperature monitoring values ​​of each monitoring module are within the fluctuation threshold range, the chemical equipment is judged to be normal, and step B is repeated. In step D, the set fluctuation threshold for the temperature monitoring values ​​of each monitoring module 1 is within 5 to 10 degrees Celsius. When the temperature monitoring values ​​of each monitoring module 1 exceed the fluctuation threshold, a risk point is established for the equipment, and maintenance is required. The fluctuation threshold for the temperature monitoring values ​​is determined based on the amount of reactants; generally speaking, the larger the amount of reactants, the higher the designed value of the fluctuation threshold.

[0039] The method of this application first monitors the liquid level and the rate of liquid level reduction inside the chemical equipment to determine the leakage situation of the chemical equipment, which corresponds to the most important detection content of chemical equipment safety. Then, it monitors the overall concentration of reactants, internal temperature of chemical equipment and pH value. When these are all normal, it uses multiple monitoring modules set up at multiple points to achieve lateral comparative detection of local areas of chemical equipment. In step D, when stress deformation occurs inside the chemical equipment, the reaction rate of reactants and temperature environment will change relative to other normal areas. Lateral comparison can quickly find the problem location. At this time, the chemical equipment as a whole is in normal working condition, but the actual equipment has already shown a risk point. The relevant location can be detected intuitively and quickly through this monitoring system and method.
