Description
Technical Field
[0001] The utility model belongs to the technical field of control room operating tables, and in particular relates to an intelligent anti-corrosion central control room operating table. Background Art
[0002] Coking enterprises, due to the complex process flow, usually have multiple central control rooms such as energy management and control center, methanol control room, chemical production control room, coking control room, gasification control room, comprehensive water control room, coal preparation control room, etc. The high failure rate of electronic components and equipment in the central control room operating table due to gas corrosion, dust accumulation short circuit, and component heating has become the number one problem that plagues the company's safe and stable production. The main reasons for the high failure rate include the following:
[0003] 1. There are corrosive gases in the air in the chemical production area and the coking waste heat desulfurization and denitrification area. With different wind directions, the corrosive gases will drift to the chemical production control room, the coking control room, and the central control room of the energy management and control center, causing the surface of the electronic components and circuit boards in the operating table to be corroded, resulting in a high equipment failure rate;
[0004] 2. The air in the coke oven and coal preparation area contains a large amount of dust particles. The operation tables in the coke control room, energy control center, and coal preparation control room are seriously dusty. There is a phenomenon that dust is cleaned every day but appears again the next day. Since the production monitoring computers and other equipment do not have the conditions to clean the dust on the chassis every day, the computer failure rate is high, affecting the normal monitoring operation;
[0005] 3. With the renovation of original projects and the increase of new safety and environmental protection projects, the control room operation tables are constantly adding computer mainframes, optical fiber boxes for remote signal transmission, optical fiber transceivers and matching 24V power modules, video monitoring hosts, switches, time servers, industrial intercoms, monitoring computer alarm speakers and other electronic equipment. The storage space in the operation table is seriously insufficient, and the equipment is stacked together without any heat dissipation equipment and measures, causing the components to heat up and cause equipment failures;
[0006] 4. The operating table is not tightly sealed, and the components heat up, attracting small animals to enter the operating table to keep warm, frequently biting off the optical fiber in the optical fiber box, causing the monitoring computer communication to be interrupted, making it impossible to monitor the production operation normally, and creating serious safety hazards;
[0007] 5. There is no emergency stop button on the operating table. In order to meet production needs, the self-installed emergency stop button box is placed outside the operating table, which not only occupies the limited operating table space, but also causes the button wire to be exposed on the operating table. The 220V voltage is very likely to cause electric shock or accidental contact with the cable, causing an emergency stop accident of the unit;
[0008] 6. With the increasing number of monitoring equipment on the operating table, the monitoring computer monitors and video recording monitors can only be fixed and installed using double-layer monitor brackets. The brackets are deformed due to long-term stress, resulting in different display angles of the four monitors. Operators cannot look directly at them and need to adjust the angle all the time. This not only easily causes visual fatigue, but also requires frequent adjustment of the display angle, which increases the difficulty of monitoring.
[0009] Therefore, an intelligent anti-corrosion central control room operating console is proposed. Utility Model Content

[0036] The following is a detailed description of the design of the above key components:
[0037] An external docking port 1 is disposed on one side of the bottom of the operating table 23 , and an air source pipe 4 is connected to the docking port 1 and passes through the bottom of the operating table 23 . An air filter pressure reducer 2 and a micro-pressure regulating valve 3 are installed on the air source pipe 4 .
[0038] A micro-pressure sensor 8 and a power strip 18 are arranged on the inner wall of the operating table 23 , and terminal blocks 7 are arranged on the inner walls on both sides of the operating table 23 .
[0039] The partition plate 9 is provided with a circular hole, and the column 17 is provided with a plug hole.
[0040] Four drawers 10 are arranged in the protruding table top 26 , and a wire passing hole 27 is arranged on the protruding table top 26 .
[0041] An optional panel is reserved on one side of the display 11 , and an emergency stop button 14 , an emergency stop button 2 15 and a reset button 16 are arranged on the optional panel.
[0042] The cabinet door 21 is designed as a swing door. Latch pins 19 are arranged at the upper and lower parts of the cabinet door 21 , and a cabinet door lock 22 is arranged on the cabinet door 21 .
[0043] An exhaust fan 20 is installed on the upper inner side of the cabinet door 21 at the back of the operating table 23 .
[0044] A mesh partition door 24 is disposed at the upper rear of the side wall of the operating table 23 .
[0045] The surface of the mesh partition door 24 is evenly provided with circular holes, and a guide rail 25 is installed on the mesh partition door 24 .
[0046] The main functions are as follows:
[0047] 1. The positive pressure ventilation control system ensures that the operating table 23 has the functions of corrosion resistance, dust resistance and moisture resistance.
[0048] Gas source pipes 4 are laid in each production area of the coking enterprise. An external docking port 1 is arranged on one side of the bottom of the operating table 23 to facilitate the introduction of instrument gas source into the operating table 23. An air filter pressure reducer 2 is installed in the operating table 23 to purify and pressure-regulate the instrument gas.
[0049] After the purified instrument air is decompressed and adjusted to 400Pa-800Pa by the air filter, it enters the operating table 23 along the air source pipe 4. A micro-pressure sensor 8 is arranged on the inner wall of the operating table 23. The micro-pressure sensor 8 is used to sense the micro-pressure in the operating table 23. Terminal blocks 7 are arranged on the inner walls of both sides of the operating table 23. The pressure signal is connected to the terminal block 7 through a prefabricated transmission cable, so that after the subsequent installation of the operating table 23, the micro-pressure signal is transmitted from the terminal block 7 to the production control system;
[0050] A micro-pressure regulating valve 3 is installed on the gas source pipe 4 at the bottom of the operating table 23. The micro-pressure regulating valve 3 adjusts the instrument gas source flow by receiving the PID-adjusted valve opening signal sent by the production control system, thereby ensuring that the gas pressure in the operating table 23 is maintained at 200Pa~300Pa, preventing corrosive gases, dust and moisture from entering the operating table 23, cutting off the risk of corrosive gases and dust entering, and reducing the failure rate of equipment in the table.
[0051] 2. The heat dissipation control system ensures that the operating table 23 has good cooling and heat dissipation functions.
[0052] A temperature sensor is installed in the operating table 23, and the temperature signal is connected to the terminal block 7 of the operating table 23 through a prefabricated transmission cable, so that after the operating table 23 is installed, the temperature signal can be transmitted from the terminal block 7 to the production control system; an exhaust fan 20 is installed on the upper inner side of the cabinet door 21 on the back of the operating table 23.
[0053] like Figure 5 As shown, when the temperature in the operating table 23 is higher than 40°C, the exhaust fan 20 will receive a start signal sent by the production control system. The exhaust fan 20 will run to exhaust the hot air out of the operating table 23, so that the gas circulation in the operating table 23 is maintained, and the heat emitted by the components is also taken away, which has a good heat dissipation effect. The heat emitted by the components is dissipated in time, the operation of the components is relatively stable, and the life of the entire control system is correspondingly extended.
[0054] On the contrary, when the temperature in the operating table 23 is lower than 25° C., the exhaust fan 20 will receive a stop signal sent by the production control system, thereby achieving the purpose of saving energy.
[0055] 3. Automatic safety device to ensure that the operating table 23 maintains a slightly positive pressure state.
[0056] 3.1 High voltage limiting protection function.
[0057] like Figure 4 As shown, the production control system compares the collected micro-pressure in the operating console 23 with the set high pressure value of 400Pa. When the pressure is high, an interlock command to fully close the micro-pressure regulating valve 3 is issued. When the pressure in the operating console 23 collected by the production system drops to 250Pa, the interlock command to fully close the micro-pressure regulating valve 3 disappears, and the micro-pressure regulating valve 3 re-enters the PID self-adjusting state to ensure that the operating console 23 will not be deformed or damaged due to high-pressure impact; the production control system compares the collected micro-pressure in the operating console 23 with the set low pressure value of 50Pa. When the pressure is low, an interlock command to fully open the micro-pressure regulating valve 3 is issued. When the pressure in the operating console 23 collected by the production system rises to 250Pa, the interlock command to fully open the micro-pressure regulating valve 3 disappears, and the micro-pressure regulating valve 3 re-enters the PID self-adjusting state to ensure that the operating console 23 will not lose the positive pressure working environment due to low pressure.
[0058] 4. The operating table 23 monitoring alarm system can effectively identify high and low pressure alarms and high temperature alarms.
[0059] The production control system compares the collected micro-pressure inside the operating console 23 with the set low pressure value of 100Pa. When the pressure is low, a low-pressure sound and light alarm is issued; the micro-pressure inside the operating console 23 is compared with the set high pressure value of 350Pa. When the pressure is high, a high-pressure sound and light alarm is issued; the production control system compares the collected temperature inside the operating console 23 with the set high temperature value of 35°C. When the temperature is high, a high-temperature sound and light alarm is issued.
[0060] 5. Equipment should be classified and placed in layers to facilitate later maintenance and heat dissipation of the equipment.
[0061] The space under the operating table 23 is freely adjustable by the bolt adjustment method. Vertical columns 17 with sockets are arranged on both sides of the operating table 23. Each layer of equipment is separated by a partition 9 with circular holes. There is a bolt 19 at the connection between the partition 9 and the column 17. The bolt 19 can be inserted into different sockets of the column 17 to adjust the space of the upper and lower partitions 9. In this way, each electrical equipment can freely adjust the distance between each layer of partitions 9 according to the size, and can also stand the equipment without the partition 9, realizing the maximum space utilization. At the same time, the design of the hole-type partition 9 increases the air circulation, which can effectively ventilate and cool.
[0062] After the rear cabinet door 21 above the operating table 23 is opened, upright mesh partition doors 24 that can be opened outward are provided on the two side walls inside the operating table 23. The partition 9 is fixed to the side walls of the operating table 23 by hinges. Circular holes are evenly arranged on the surface of the mesh partition door 24, and the size of the holes is consistent with the size of the fixing screws delivered with the operating table 23.
[0063] Lightweight and small-sized ear-hanging devices such as optical fiber transceivers, 24V power modules, 8-port small switches, industrial intercoms, etc. can be directly fixed on the partition 9 using screws; guide rail-type fixed devices can also be easily installed on the partition 9 by installing the guide rail 25.
[0064] 6. The operating table is designed with 23 blocks to prevent small animals.
[0065] The upper and lower cabinet doors 21 of the operating table 23 are designed as flat doors, and latches 19 are provided on the upper and lower parts of the cabinet doors 21 to prevent the cabinet doors 21 from deforming and sinking, resulting in poor sealing. A wire inlet 5 is left at the bottom of the operating table 23, and the wire inlet 5 is blocked by a rubber plate with a metal mesh. The size of the hole can be cut according to actual conditions, and explosion-proof clay is provided to fill the gap of the wire inlet 5, thereby ensuring the sealing of the operating table 23 and effectively preventing small animals from entering.
[0066] 7. Reserve an optional area for installing an emergency stop button.
[0067] An optional area for emergency stop buttons is reserved on the side of the display 11. If an emergency stop button is required, an optional board with an emergency stop button can be selected. The optional board is equipped with two emergency stop buttons and a reset button 16. When the two emergency stop buttons are pressed at the same time, an emergency stop command is issued. Plastic covers are provided above the three buttons to prevent accidental contact. Otherwise, an empty back panel is directly installed in the optional area.
[0068] 8. The display 11 is laid flat in layers to prevent visual fatigue.
[0069] The upper layer of the operating table 23 has four installation openings for the monitors 11. The installation position meets the operator's eye level requirements. The reserved size of the installation opening is based on the standard 24-inch monitor 11 size, and the size can also be customized according to customer requirements. The four windows are marked with visual numbers, corresponding to the four keyboard and mouse drawers 10.
[0070] 9. Grounding busbar 6, anti-electric shock function.
[0071] A grounding busbar 6 is provided at the bottom of the operating table 23, a grounding screw is installed on the cabinet door 21, and the grounding wire is connected to the grounding busbar 6. The grounding of the operating station and RTU and other equipment can be directly connected to the grounding busbar 6 to prevent electric shock and ensure personal safety.
[0072] 10. Four drawers 10 are arranged in the central protruding table 26 of the operating table 23 for placing keyboards and mice of four monitors 11. The arrangement positions are consistent with the arrangement positions of the monitors 11 and are visually numbered to avoid confusion about the correspondence between the keyboard, mouse and monitor 11, which may cause misoperation.
[0073] 11. In terms of software, the control schematics, wiring diagrams and packaged logic program segments use common control systems, such as the control program segments of Siemens STEP7 / Honey PKS system / Hollystone V6 / Sinocontrol ECS700 / Nanjing Sciyon NT6000, etc., which are convenient for users to directly import program segments, write and debug, and realize the pressure, temperature control, alarm and protection functions of the operating console 23.
