Description

Technical Field

[0001] The invention belongs to the technical field of desulfurization tower slurry waste heat recovery, and relates to a high-efficiency slurry heat recovery module and a desulfurization tower slurry waste heat recovery and utilization system. Background Art

[0002] With the rapid advancement of global industrialization, energy demand continues to grow. At the same time, energy consumption and environmental pollution problems generated in industrial production processes are becoming increasingly prominent. Especially in the combustion of fossil fuels, a large amount of harmful gases such as sulfur dioxide are emitted into the atmosphere, posing a serious threat to the environment and human health. In order to mitigate these negative impacts, flue gas desulfurization (FGD) technology has become an indispensable environmental protection measure in many industrial fields, especially in the power, chemical, steel and other industries.

[0003] In the process of flue gas desulfurization, the spray tower is a commonly used equipment. It achieves the purpose of desulfurization by spraying absorbent slurry into the tower to fully contact with the flue gas containing sulfur dioxide. In this process, the slurry not only absorbs pollutants in the flue gas, but also absorbs a large amount of heat in the flue gas, causing the slurry temperature to rise. However, the existing desulfurization system often ignores the potential value of this part of heat energy, so that the waste heat of the slurry after desulfurization is directly discharged into the environment, resulting in a huge waste of energy. In addition, there are some technical difficulties in the operation of the existing desulfurization system. After absorbing heat, the slurry is prone to form dirt on the surface of the heat exchanger, which reduces the heat exchange efficiency and increases the energy consumption and maintenance cost of the system. At the same time, the system has a low degree of automation and relies on manual operation and monitoring, which not only increases labor costs, but also limits the system's ability to respond quickly to emergencies.

[0041] refer to Figure 1 The desulfurization tower slurry waste heat recovery and utilization system of the present invention includes a spray slurry absorption module, a slurry circulation pump, a high-efficiency slurry heat recovery module, a heat pump module, a return water heating module, a control system module, a self-cleaning and anti-scaling module, a cloud monitoring and remote diagnosis module and auxiliary equipment;

Specifically, the rectangular plate 16 is connected to the internal low-frequency vibrator 8 through connecting screws 17, and an external low-frequency vibrator 7 is provided at the lower end of the internal low-frequency vibrator 8.

[0044] A first annular plate 4 is provided on one end surface of the heat exchanger body 1, and a second annular plate 14 is provided on the other end surface of the heat exchanger body 1, a cold flow water inlet 5 is provided on the first annular plate 4, and a cold flow water outlet 13 is provided on the second annular plate 14.

[0045] Fixing bolts 12 with nuts 11 are disposed on the first annular plate 4 and the second annular plate 14 .

[0047] A display screen 10 and a plurality of buttons 9 are provided on the side of the external low-frequency vibrator 7, wherein the display screen 10 is convenient for displaying the operation status of the internal low-frequency vibrator 8, so as to facilitate observation by the staff, and by using the buttons 9, it is convenient for the staff to control the operation of the internal low-frequency vibrator 8, so as to meet different operation needs.

[0048] It should be noted that the outer shell of the heat exchanger body 1 is composed of multiple layers of material, specifically including a carbon steel layer 18 and a stainless steel layer 19, wherein the carbon steel layer 18 has good strength and hardness and can withstand greater pressure, and the stainless steel layer 19 has excellent corrosion resistance to most chemical media and is particularly suitable for use in highly corrosive environments. At the same time, it can withstand high temperature environments and is suitable for heat exchangers for high-temperature fluids.

[0049] During operation, the control system controls the operation of the external low-frequency vibrator 7 and the internal low-frequency vibrator 8 to remove dirt or sediment attached to the inner wall of the heat exchanger body 1 to maintain efficient heat exchange. By applying low-frequency vibration, the sediment has weak adhesion on the surface of the equipment and is thus washed away. When in use, the operation of the internal low-frequency vibrator 8 is turned on to facilitate the cleaning operation.

[0050] During operation, the slurry circulation pump transports the slurry after absorbing heat to the high-efficiency slurry heat recovery module for heat exchange. The high-efficiency slurry heat recovery module transfers the heat in the slurry to the evaporator of the heat pump module. The heat pump module increases the heat quality through the compressor and then transfers it to the condenser of the heat pump module. The condenser of the heat pump module transfers the heat to the return water, and the heated return water is transported to the heating water tank through the return water pump for user use.

[0051] The control system is connected with the spray slurry absorption module, slurry circulation pump, high-efficiency slurry heat recovery module, heat pump module and return water heating module. The control system collects the system operation data through sensors and monitors and operates through the human-machine interface. The control system is also responsible for adjusting the operating parameters of each module to ensure the system is efficient and stable.

[0052] A filter is provided between the spray slurry absorption module and the slurry circulation pump to prevent impurities from entering the high-efficiency slurry heat recovery module and realize the flow of the medium.

[0053] The self-cleaning and anti-scaling module is connected to the high-efficiency slurry heat recovery module. The self-cleaning and anti-scaling module includes an ultrasonic anti-scaling device and a self-cleaning filtration system. The ultrasonic anti-scaling device is installed on the high-efficiency slurry heat recovery module to prevent scaling. The filter screen in the filter is automatically cleaned by the self-cleaning filtration system to keep the system clean.

[0054] The control system uploads the system's operating parameters to the cloud monitoring and remote diagnosis module to achieve remote monitoring. The cloud monitoring and remote diagnosis module performs remote diagnosis and maintenance guidance based on the system's operating parameters.

[0055] The spray slurry absorption module fully contacts the desulfurization slurry with the flue gas through the spray tower, so that the slurry absorbs the heat in the flue gas, wherein pollutants such as sulfur dioxide in the flue gas are captured by the absorbent in the slurry, thereby achieving the desulfurization effect. The spray tower is equipped with multiple layers of nozzles, which atomize the slurry into fine particles to increase the contact area with the flue gas. During operation, the flue gas enters from the bottom of the tower and contacts the slurry from top to bottom in reverse. After the heat is transferred to the slurry, the purified flue gas is discharged from the top of the tower.

[0056] The slurry circulation pump extracts the slurry that absorbs the flue gas from the bottom of the spray tower and transports it to the high-efficiency slurry heat recovery module. The selection of the slurry circulation pump needs to be determined according to the flow rate, head and viscosity of the slurry. During operation, the start and stop and speed of the slurry circulation pump are adjusted by the control system according to the temperature of the slurry in the absorption tower and the desulfurization efficiency to ensure stable operation of the system.

[0057] The high-efficiency slurry heat recovery module utilizes the heat in the slurry to heat the circulating water. In the high-efficiency slurry heat recovery module, the slurry exchanges heat with the circulating water through a plate heat exchanger or a shell and tube heat exchanger. After the heat in the slurry is absorbed by the circulating water, the slurry with a reduced temperature returns to the spray tower, and the heated circulating water flows to the heat pump module.

[0058] The heat pump module uses heat pump technology to further increase the temperature of circulating water and achieve efficient thermal energy utilization. The heat pump module includes components such as a compressor, an expansion valve, and an evaporator to increase the heat of a low-temperature heat source to a higher temperature that can be used for heating or water supply. In the system, the heat pump module absorbs heat from the circulating water and releases it to the return water heating module, thereby increasing the temperature of the return water.

[0059] The return water heating module transfers the heat provided by the heat pump module to the return water, so that the return water temperature meets the user's requirements. The return water heating module includes a hot water storage tank and a circulating heating system. The heated return water can be used for heating, bathing or other occasions where hot water is required. The design of the return water heating module must ensure efficient transfer of heat energy and stable water temperature output.

[0060] The control system is the central nervous system of the whole system, responsible for monitoring and adjusting the operating status of each module. The control system includes sensors, actuators, PLC controllers and HMI (human-machine interface). The control system automatically adjusts the operating parameters of the slurry circulation pump, heat pump module and high-efficiency slurry heat recovery module according to the preset program and real-time data to ensure efficient and stable operation of the system.

[0061] The self-cleaning and anti-scaling module is used to prevent scaling inside equipment such as heat exchangers and ensure long-term stable operation of the system.

[0063] Specifically, the data acquisition and transmission system includes an acquisition module and a data transmission unit; the acquisition module is used to collect real-time operating data of the system such as temperature, pressure, flow and liquid level; the data transmission unit (DTU) is used to convert the real-time operating data of the system into digital signals and upload them to the cloud through the Internet.

[0064] The cloud server includes a data storage center and a data processing and analysis engine; the data storage center is used to store historical data and real-time data of system operation; the data processing and analysis engine is used to process, analyze and process the system operation data to extract useful information.

[0065] The remote monitoring platform includes a user interface and a control instruction issuing module; the user interface is used to provide an intuitive graphical interface for operators to view system status, alarm information and historical data; the control instruction issuing module is used to allow remote operators to send control instructions to on-site equipment.

[0066] The early warning and fault diagnosis system includes an early warning algorithm and a fault diagnosis model; the early warning algorithm is used to predict and alarm potential operating risks based on historical data and preset thresholds; the fault diagnosis model is used to learn and identify the system's fault modes according to the system's operating parameters through a machine learning algorithm.

[0067] The maintenance and management module includes a maintenance plan generator and a maintenance record management system; the maintenance plan generator is used to automatically generate a maintenance plan based on the system's operating conditions and equipment maintenance cycles; the maintenance record management system is used to record maintenance history and provide data support for the long-term operation of the equipment.

[0068] The operation method of the cloud monitoring and remote diagnosis module includes:

[0069] 1) Obtain the system operation data and convert the system operation data into digital signals;

[0070] 2) Packaging the digital signal and sending it to a cloud server;

[0071] 3) The data storage center in the cloud server stores the received data, and then analyzes the data through the data processing and analysis engine, and the analysis includes but is not limited to: trend analysis, performance evaluation, energy consumption calculation and fault prediction;

[0072] 4) Operators log in to the system through the user interface of the remote monitoring platform to view real-time data and historical records. The user interface provides charts, dashboards and alarm notifications so that operators can quickly understand the system status.

[0073] 5) The system’s operating data is monitored through an early warning algorithm, and the system’s operating data is compared with the preset threshold. When potential risks or anomalies are detected, an early warning is triggered immediately, and relevant personnel are notified via SMS, email, etc.

[0074] 6) The fault diagnosis model analyzes the system's operating data, identifies possible failure modes and causes, and provides maintenance personnel with diagnostic results and recommended solutions.

[0078] 10) Using the collected data and analysis results, the system operation strategy is optimized, and the optimization goals include improving efficiency, reducing costs, and saving energy and reducing emissions.

[0079] It should be noted that the auxiliary equipment includes insulation materials, filters, valves, pipes, etc., which provide support and guarantee for the normal operation of the system. Insulation materials are used to reduce heat loss and improve system efficiency; filters are used to intercept impurities in the slurry to prevent blockage of heat exchangers and heat pumps; valves and pipes are responsible for connecting various modules to ensure that the medium flows according to the designed process. The selection and installation of these auxiliary equipment must take into account the corrosion resistance, temperature resistance and long-term reliability of the system.

[0080] In the present invention, the spray slurry absorption module atomizes the slurry through multi-layer nozzles, which greatly increases the contact area between the slurry and the flue gas, thereby improving the desulfurization efficiency and effectively removing pollutants such as sulfur dioxide in the flue gas. While desulfurizing, the slurry absorbs the heat in the flue gas, which makes it possible for subsequent heat recovery and realizes the secondary utilization of energy. The high-efficiency slurry heat recovery module is the core of waste heat recovery. It transfers the heat in the slurry that has absorbed heat to the circulating water, realizes the effective recovery of thermal energy, and improves the overall energy efficiency of the system. By lowering the temperature of the slurry, the high-efficiency slurry heat recovery module helps to reduce the corrosion of the slurry to equipment such as spray towers and circulating pumps, thereby extending the service life of the equipment. The design and operation of the high-efficiency slurry heat recovery module ensures that the system is stable and efficient in the process of absorbing and transferring heat, providing a guarantee for the continuous operation of the entire system.

[0081] The cloud monitoring and remote diagnosis module enables operators to monitor the operating status of the system anytime and anywhere through real-time data collection and upload, without having to go to the site in person, which greatly improves management efficiency and convenience. The early warning algorithm of this module can monitor system parameters in real time and compare them with preset thresholds. Once an abnormality is found, it will immediately trigger an early warning and notify relevant personnel so that timely measures can be taken to prevent the occurrence of failures. By analyzing system data, the fault diagnosis model can identify fault modes and propose solutions, provide maintenance personnel with precise maintenance guidance, reduce diagnosis time, and improve maintenance efficiency. Through in-depth analysis of the collected data, the system can optimize operation strategies, improve energy efficiency, and reduce operating costs. Regularly generated maintenance plans help ensure that equipment is properly cared for and maintained, thereby extending the service life of equipment and reducing replacement costs.

[0082] The self-cleaning filtration system automatically cleans the filter screen to prevent the accumulation of impurities, ensure the internal cleanliness of the system, and reduce the efficiency loss and equipment damage caused by the accumulation of dirt. The ultrasonic anti-scaling device can effectively prevent the internal scaling of equipment such as heat exchangers, maintain the heat exchange efficiency, and avoid energy waste and equipment damage caused by scaling. The self-cleaning and anti-scaling module reduces the frequency of manual cleaning and maintenance, reduces maintenance costs, and reduces production losses caused by downtime maintenance. By preventing scaling and fouling, the system runs more stably, reduces downtime caused by equipment failure, and improves the reliability of the overall system. It reduces the corrosion and wear of equipment caused by scaling and fouling, thereby extending the service life of the equipment and reducing the frequency and cost of equipment replacement.
