Description

Technical Field

[0001] This utility model relates to the field of waste station monitoring systems, specifically to a centralized monitoring system for kitchen waste coalification treatment facilities. Background Technology

[0002] Currently, my country has a large number of traditional garbage stations. The supporting equipment of traditional garbage stations is relatively simple, including atomization and negative pressure deodorization, roller shutters, weighing and simple remote control systems. Their equipment management is extensive, the level of automation control is low, and their functions are simple, mainly for garbage transfer.

[0003] Kitchen waste is a large amount of high-moisture, low-calorific-value biomass waste generated from household waste sorting. It is characterized by easy rotting, odor, and biodegradability. Traditional waste stations are no longer suitable for kitchen waste treatment, resulting in low overall resource recycling efficiency and the "not in my backyard" (NIMBY) problem has not been effectively solved.

[0004] With the continuous development of society and the constant updating and advancement of technology, traditional garbage station monitoring systems can no longer meet the increasingly strong demand for information-based supervision of garbage classification and treatment.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1 The present invention provides the following technical solution: a centralized monitoring system for kitchen waste coalification treatment facilities, including an automated centralized monitoring system 1, an automated equipment information collection box 2, an online odor monitoring system 3, a large screen display system 4, an online sewage monitoring system 5, a video monitoring system 6, and a treatment facility control system.

[0034] The treatment facility control system includes subsystems such as a sub-high-pressure dry and wet classification subsystem 7, an odor control subsystem 8, a coal chemical treatment subsystem 9, a power monitoring subsystem 10, a weighing system 11, and a sewage treatment subsystem 12. Each subsystem of the treatment facility control system is connected to the same switch and network-connected to the automated centralized monitoring system 1, thereby realizing point-to-point network communication between the subsystems and enabling the automated centralized monitoring system 1 to centrally manage and control all equipment control subsystems.

[0035] The automated centralized monitoring system 1 includes hardware such as automated integration software and servers. Its main functions are to collect status information of automated equipment in coal chemical processing facilities, display simulated screens, perform interlocking control logic operations, display alarms, and record and query data. Operators can issue control commands and adjust production parameters based on equipment status information, facilitating centralized control and status awareness of automated equipment in coal chemical processing facilities and improving work efficiency.

[0036] The three functions of the automated centralized monitoring system 1.

[0037] Centralized monitoring function:

[0038] The automated centralized monitoring system 1 monitors the operating status, alarm signals, energy consumption data, inbound and outbound waste volume, and instrument data of all equipment within the subordinate equipment monitoring system, and displays them dynamically through a simulated screen.

[0039] Centralized control operation functions:

[0040] The automated centralized monitoring system 1 has remote control operation capabilities for all equipment within its monitoring system, specifically including remote manual mode operation, semi-automatic mode operation, and production process parameter adjustment. Remote manual mode operation refers to performing single-action operations on subordinate equipment, while semi-automatic mode operation refers to executing system-level combined operation commands, with multiple devices performing interlocking actions.

[0041] Data recording and query functions:

[0042] The automated centralized monitoring system 1 records the operating status data of subordinate equipment through a historical database and displays real-time and historical data in the form of data lists, trend charts, alarm windows, etc.

[0043] The automated equipment information collection box 2 is network-connected to the automated centralized monitoring system 1, collecting status information and production data of the automated equipment in the coal chemical treatment facility, and transmitting the data to the monitoring platform 13 via the Internet. The data collected and forwarded by the automated equipment information collection box 2 includes: the start / stop status and energy consumption of the dry and wet sorting equipment; the coal chemical treatment volume and energy consumption; the wastewater system treatment volume, energy consumption, and discharge volume; and key data such as the start / stop status, energy consumption, and fan operating frequency of the negative pressure deodorization equipment. This enables regulatory authorities to monitor the status of the coal chemical treatment facility's equipment.

[0044] The large-screen display system 4 includes multiple high-definition display units, a splicing screen controller, an LED display screen, and other equipment. The overall process screen of the automated centralized monitoring system 1, the client interface of the wastewater online monitoring system 5, the client interface of the odor online monitoring system 3, and the client screen of the video monitoring system 6 are connected to the splicing screen controller via electrical connection. Through the splicing screen controller's screen splicing and roaming display functions, various screen combination modes can be displayed. The LED display screen is mainly used for displaying welcome messages and other information.

[0045] The aforementioned odor online monitoring system 3, wastewater online monitoring system 5, video monitoring system 6, and weighing system 11 are mature, integrated products on the market, and will not be described in detail here. The data from the above four systems are connected to the regulatory platform to meet the regulatory authorities' requirements for comprehensive information supervision of coal chemical treatment facilities.

[0046] Specifically, the sub-high-pressure dry and wet sorting subsystem 7 has a control unit that includes a sub-high-pressure dry and wet sorting equipment control 21, a wet waste conveying pump control 22, and a homogenizing slurry equipment control 23. Its control strategy is as follows: after the automated centralized monitoring system 1 issues a start / stop command for the sub-high-pressure dry and wet sorting system, it automatically starts and stops the dry and wet sorting equipment, the wet waste conveying pump, and the homogenizing slurry equipment in sequence.

[0047] Specifically, the coal chemical treatment subsystem 9 includes control units for a buffer tank 31, a system feed pump 32, a catalyst addition 33, a heating device 34, a coal chemical reactor 35, a coal discharge 36, and a plate and frame filter press 37. The control strategy for the coal chemical treatment subsystem 9 is as follows:

[0048] (1) Automatic switching control of feed valve and discharge valve of two buffer tanks: The buffer tanks feed in turn. When one buffer tank feeds and its liquid level reaches the high level, it stops feeding and the buffer tank automatically switches to the discharge state, while the other buffer tank switches to the feed state.

[0049] (2) Automatic interlocking start and stop control of system feed pump and automatic frequency adjustment: When the operator issues the "system feed automatic start" command through the automated centralized monitoring system, the buffer tank discharge valve and the coal chemical reactor feed valve are automatically interlocked and executed. After the two valves are in place, the feed pump starts running. The feed pump running frequency value is automatically adjusted to maintain the stability of the liquid level in the coal chemical reactor.

[0050] (3) Automatic start-stop operation of catalyst addition and automatic frequency adjustment: The catalyst metering pump is interlocked with the feed pump start-stop control, and its operating frequency value is adjusted synchronously according to the system feed pump frequency to ensure the stability of catalyst ratio.

[0051] (4) Automatic operation of heating device: The heating device contains a temperature controller, which automatically maintains the target temperature. The integrated screen displays the status parameters of the heating device controller and the temperature value of the device. When the system is over-pressurized or the system feed pump stops running, the heating device will automatically stop running. To restart, the operator needs to click the "Automatic start of heating device" command again.

[0052] (5) Automatic control of feed valve, automatic control of stirring, and monitoring of liquid level, pressure and temperature of coal chemical reactor: When the system feed pump starts, the feed valve opens first; the reactor stirring starts and runs periodically according to the set time.

[0053] (6) Automatic control of coal chemical discharge pressure and automatic adjustment of flow rate: The discharge pressure value is controlled within the allowable range by adjusting the opening of the pressure regulating valve, and the flow rate value of the discharge flow meter is stabilized and reaches the set value by adjusting the opening of the discharge regulating valve.

[0054] (7) Remote automatic control of plate and frame filter press: filter press feed control, secondary filter press control and discharge control.

[0055] Specifically, the wastewater treatment subsystem 12 includes control units for oil-water separation and sedimentation pretreatment 41, high-efficiency adsorption 42, ultrafiltration membrane system 43, nanofiltration membrane system 44, reverse osmosis membrane system 45, and bottom sludge return 46. All major control units of the wastewater treatment subsystem operate fully automatically. Bottom sludge return 46 refers to the control of returning bottom sludge from the wastewater treatment tank to the plate and frame filter press in the coal chemical system. Its interlocking control strategy is as follows:

[0056] (1) After the sewage treatment system meets certain conditions (reaches a certain operating time or treatment volume), the sewage field operator issues a "request sludge return" command through the field control panel. The central control operator sees the "request sludge return" command message through the centralized monitoring system interface, and switches the filter press to the "allow sludge return" working state in combination with the filter press status. The coal chemical system opens the filter press sludge return valve.

[0057] (2) After receiving the “allow bottom sludge return” and “bottom sludge return valve open” signals through data communication, the sewage treatment subsystem 12 starts the bottom sludge return control program.

[0058] (3) After the bottom mud return control process is completed according to the conditions, the "Request bottom mud return" command is automatically canceled, and the communication interlock cancels the filter press "Allow bottom mud return" working status and executes the bottom mud return valve to close in place.

[0059] Specifically, the odor control subsystem 8 includes control units for a factory area atomization control 51, a workshop atomization control 52, and a negative pressure deodorization control 53. The factory area atomization control 51 and workshop atomization control 52 are timed to start and stop according to operating hours to prevent odor leakage from the factory area and workshop during operation. The main control strategy of the negative pressure deodorization control 53 is as follows: the fan is set with different operating frequencies based on the different start-stop combinations of equipment at different odor sources; the number of plasma deodorization lamps turned on is interlocked and adjusted according to the different operating frequencies of the fan. The specific control strategy is as follows.

[0060] Odor source 1 – secondary high-pressure dry-wet sorting equipment, odor source 2 – buffer tank, and odor source 3 – plate and frame filter press workshop. The automated centralized monitoring system 1 collects start / stop signal data from the odor source equipment and forwards it to the odor control subsystem 8. When the number of operating odor source equipment is less than or equal to 1, the negative pressure fan operates at the first frequency level (30Hz), and 3 / 5 of the plasma lamps are turned on; when the number of operating odor source equipment is equal to 2, the negative pressure fan operates at the second frequency level (40Hz), and 4 / 5 of the plasma lamps are turned on; when the number of operating odor source equipment is equal to 3, the negative pressure fan operates at the third frequency level (50Hz), and all plasma lamps are turned on.

[0061] Specifically, the power monitoring subsystem 10 includes multiple smart meters and a protocol converter. The smart meters record the real-time operating power and electricity consumption of each subsystem device in the equipment monitoring system, and the data is connected to the automated centralized monitoring system 1 through the protocol converter.

[0062] Although embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
