Description

Technical Field

[0001] This utility model relates to the field of dry quenching technology, and in particular to an integrated cyclone dust removal dry quenching boiler wastewater temperature interlocking control system. Background Technology

[0002] The integrated cyclone dust collector dry quenching coke boiler mainly consists of two parts: a cyclone primary dust collector and an integrated dry quenching coke boiler. The cyclone primary dust collector can effectively reduce the dust content and concentration in the circulating gas at the boiler inlet, and also reduce the flue gas temperature at the superheater of the integrated dry quenching coke boiler, thus protecting the superheater.

[0003] In the actual operation of the dry quenching process, the wastewater generated by the integrated dry quenching boiler is usually maintained at a high temperature of 100-150℃. When this high-temperature wastewater is directly discharged into the collection well, a sudden drop in pressure will trigger a violent flash evaporation phenomenon. This phenomenon leads to a large accumulation of steam in the collection well, resulting in a serious backflow problem and causing multiple negative impacts on the entire process system and on-site operations.

[0004] Sustained high temperatures significantly accelerate the corrosion rate of water collection wells and surrounding metal equipment, shortening their normal service life. In northern regions using tightly sealed boilers, the problem of steam backflow is even more severe in winter, with large amounts of steam making visibility difficult and greatly increasing the personal safety risks for personnel working on-site. High-temperature wastewater significantly shortens the service life of equipment such as water pumps and causes continuous thermal damage to the entire drainage system pipeline.

[0005] Currently, the common solution in the industry is to install heat exchangers to cool down the high-temperature wastewater. However, this method has a very limited cooling effect and cannot fundamentally solve the temperature control problem of the collection well. Backflow and related derivative problems have not been effectively alleviated. In addition, existing collection well systems generally lack effective automatic adjustment mechanisms, and the control of wastewater temperature mainly relies on manual observation and manual water replenishment for cooling. Due to the excessive reliance on manual operation, there is a significant lag in water temperature adjustment. This not only makes the long-shaft submersible pumps installed in the collection well prone to cavitation, affecting the wastewater transportation efficiency, but also prevents the reasonable recovery and utilization of waste heat from the high-temperature wastewater, resulting in energy waste. Utility Model Content

[0022] In some embodiments, the distance between the explosion-proof infrared temperature gas phase monitoring sensor and the wellhead of the water collection well is h1, where 180mm≤h1≤220mm.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art based on this application are within the protection scope of the present utility model.

[0038] In related technologies, plate heat exchangers utilize deoxygenated water supply or circulating cooling water for heat exchange. If the water in the collection well is to be heated to below 40°C, a large heat exchange area is required, which is not economical.

[0039] This utility model provides an integrated cyclone dust collector dry quenching boiler wastewater temperature interlock control system. Its main purpose is to solve the problem of excessively high water temperature in the water collection well of the dry quenching system, leading to cavitation of the long-shaft submersible pump inside the well and ineffective utilization of the wastewater. This patent aims to fundamentally reduce the backflow problem in the water collection well through intelligent temperature monitoring and automatic cooling regulation, achieving safe, energy-saving, and automated operation, while extending equipment lifespan and reducing maintenance costs.

[0040] Figure 1 This application provides a schematic diagram of the layout of an integrated cyclone dust removal and dry quenching coke boiler wastewater temperature interlocking control system. Figure 2 for Figure 1 The diagram shown is an electrical connection structure diagram of an integrated cyclone dust removal and dry quenching boiler wastewater temperature interlock control system. Figure 1 and Figure 2As shown, this application proposes an integrated cyclone dust collector dry quenching boiler wastewater temperature interlock control system, including a water collection well 1, an integrated cyclone dust collector dry quenching boiler, a temperature acquisition device 3, a cold water replenishment device 4, and a high-temperature interlock control device 5. The integrated cyclone dust collector dry quenching boiler has a high-temperature wastewater discharge pipe 2, the outlet of which is connected to the water collection well 1. The temperature of the wastewater discharged from the high-temperature wastewater discharge pipe 2 is 100℃ to 150℃, and the pressure is 0.2MPa to 0.6MPa. The temperature acquisition device 3 is located within the water collection well 1. The cold water replenishment device 4 includes a cold water pipe 41 and an electrically controlled valve 42. The outlet of the cold water pipe 41 is located within the water collection well 1, and the electrically controlled valve 42 is located within the cold water pipe 41. The high-temperature interlock control device 5 is electrically connected to the temperature acquisition device 3 and the electric control valve 42 respectively. When the temperature value acquired by the temperature acquisition device 3 reaches the upper limit preset condition, the high-temperature interlock control device 5 opens the electric control valve 42. When the temperature value acquired by the temperature acquisition device 3 reaches the lower limit preset condition, the high-temperature interlock control device 5 closes the electric control valve 42.

[0041] The water collection well 1 is used to receive and temporarily store the wastewater discharged from the high-temperature wastewater discharge pipe 2 of the integrated cyclone dust removal dry quenching coke boiler. The volume of the well is determined according to the actual wastewater discharge volume. The high-temperature wastewater generated by the integrated cyclone dust removal dry quenching coke boiler is discharged into the water collection well 1 through the high-temperature wastewater discharge pipe 2.

[0042] The temperature acquisition device 3 must be installed in a location that can accurately measure the water temperature in the collection well 1. The cold water pipe 41 in the cold water replenishment device 4 can be connected to an industrial cooling water system or a tap water system, etc. The electrically controlled valve 42 can be a solenoid valve or an electric regulating valve, and its diameter is selected according to the required water replenishment volume.

[0043] The high-temperature interlock control device 5 can automatically control the electrically controlled valve 42. Upper and lower preset conditions are set according to process requirements. For example, the upper preset condition is that the temperature collected by the temperature acquisition device 3 is greater than or equal to the set upper limit value. The lower preset condition is that the temperature collected by the temperature acquisition device 3 reaches the set lower limit value. For example, the upper limit value is set to 39℃ and the lower limit value to 37℃ to ensure that the water temperature in the collection well 1 is below 40℃.

[0044] The technical solution provided in this application embodiment monitors the water temperature in the collection well 1 in real time through the temperature acquisition device 3. When the water temperature is detected to be too high and reaches the upper limit preset condition, the high temperature interlock control device 5 automatically opens the electric control valve 42, and the cold water replenishment device 4 starts to replenish cold water to reduce the water temperature in the collection well 1. When the water temperature is detected to be too low and reaches the lower limit preset condition, the high temperature interlock control device 5 automatically closes the electric control valve 42 and automatically stops water replenishment. The high temperature interlock control device 5 can automatically replenish cold water to the collection well 1. Compared with manual operation, this closed-loop control method has a higher response speed and adjustment accuracy, can continuously maintain the water temperature in the collection well 1 within a reasonable range, is easy to reuse, and also reduces steam accumulation, reduces equipment corrosion risk, and improves the working environment.

[0045] The reason for flash evaporation in the high-temperature wastewater entering the collection well 1 is that the sensible heat contained in the wastewater exceeds the energy that saturated water can contain at that pressure when the pressure decreases. The excess heat instantly "heats" a portion of the water into steam. The role of supplementing cold water is to absorb this excess heat, reducing the occurrence of flash evaporation from the perspective of energy balance, thereby solving the problem of cavitation of the long-shaft submersible pump 71 installed in the collection well 1 due to excessively high water temperature in the dry quenching system.

[0046] In practice, the temperature acquisition device 3 uses a remote thermometer, which is positioned below the water surface in the collection well 1. When the temperature value acquired by the temperature acquisition device 3 is greater than the first temperature threshold, the high-temperature interlock control device 5 opens the electrically controlled valve 42; when the temperature value acquired by the temperature acquisition device 3 is less than the second temperature threshold, the high-temperature interlock control device 5 closes the electrically controlled valve 42.

[0047] Therefore, this technical solution achieves automatic regulation of the water temperature in the collection well 1 through a precisely set dual-threshold control strategy (setting a first temperature threshold and a second temperature threshold). When the water temperature in the collection well 1 exceeds the first temperature threshold (e.g., 39°C) due to high-temperature wastewater discharge, the system automatically starts cold water replenishment; when the temperature drops below the second temperature threshold (e.g., 37°C), water replenishment stops. This control method effectively avoids the lag of manual operation and prevents equipment cavitation problems caused by excessively high water temperature in the collection well 1.

[0048] Using underwater-mounted remote thermometers reduces steam interference and improves the accuracy of temperature detection. This solution enhances the timeliness and reliability of temperature control.

[0049] Furthermore, embodiments of this application also propose that the temperature acquisition device 3 includes a gas phase monitoring sensor and a liquid phase monitoring sensor. The gas phase monitoring sensor is disposed above the water surface of the water collection well 1, and the liquid phase monitoring sensor is disposed below the water surface of the water collection well 1. The high temperature interlock control device 5 is electrically connected to the gas phase monitoring sensor and the liquid phase monitoring sensor respectively.

[0050] When the temperature value collected by the gas phase monitoring sensor exceeds the gas phase temperature start-up threshold, or when the temperature value collected by the liquid phase monitoring sensor exceeds the liquid phase temperature start-up threshold, the high-temperature interlock control device 5 opens the electrically controlled valve 42. For example, the gas phase temperature start-up threshold is 105℃, and the liquid phase temperature start-up threshold is 39℃, but not limited to these thresholds. Using both gas phase and liquid phase monitoring sensors to monitor and control the cooling water supply above and below the water surface can improve the accuracy of water temperature control in the collection well.

[0051] The gas phase monitoring sensor can be an explosion-proof infrared temperature gas phase monitoring sensor, used for real-time monitoring of temperature changes in the steam space within the water collection well 1. The liquid phase monitoring sensor can be a zirconium ceramic-encapsulated thermocouple liquid phase monitoring sensor. This sensor has corrosion resistance and a response time of <1s, used for accurate measurement of the water phase temperature. The installation height of the gas phase monitoring sensor from the wellhead is preferably controlled within the range of 180mm-220mm, such as 200mm below the wellhead. The installation depth of the liquid phase monitoring sensor from the water surface can be controlled within the range of 480mm-520mm, but is not limited to this. Through a dual-sensor arrangement, simultaneous monitoring of the gas and liquid phase temperatures within the water collection well 1 can be achieved.

[0052] Specifically, this technical solution, by setting up dual temperature monitoring points for both the gas and liquid phases, can more comprehensively reflect the actual temperature distribution within the water collection well 1. Compared to a single temperature monitoring solution, this design can more accurately determine the actual operating conditions of the water collection well 1, avoiding control lag or malfunctions caused by inaccurate local temperature measurements.

[0053] Furthermore, embodiments of this application also include a drainage pipe 6, the drain outlet of which is located within the sump 1. The drainage pipe 6 is used to drain liquid from the sump 1. The drain outlet may be located on the side wall of the sump 1. The diameter of the drainage pipe 6 is determined according to the drainage volume requirement. For example, when the user does not need water, the liquid level in the sump 1 reaches the height of the drain outlet of the drainage pipe 6, and the water in the sump 1 is discharged through the drain outlet of the drainage pipe 6, preventing excessive backflow of water from the sump 1 into the ditch.

[0054] Furthermore, embodiments of this application also propose that the drainage pipe 6 is installed inside the water collection well 1, and the height of the drainage outlet is lower than the height of the explosion-proof infrared temperature gas phase monitoring sensor. A certain distance is maintained between the drainage outlet and the gas phase monitoring sensor to reduce the impact of splashing water droplets on the operation of the explosion-proof infrared temperature gas phase monitoring sensor during drainage. The drainage pipe 6 can be installed at a downward tilt to facilitate smooth liquid discharge, but is not limited to this design.

[0055] Specifically, the drain outlet of drainage pipe 6 is positioned a certain distance below the installation location of the gas phase monitoring sensor. This elevation difference design ensures that the high-temperature wastewater discharged from the drain outlet first enters the bottom area of ​​the collection well 1, mixes with the bottom water, and then diffuses upwards. The gas phase monitoring sensor, located above the drain outlet, can accurately monitor temperature changes in the steam accumulation area, reducing the direct impact of drainage. As one implementation method, the drain outlet can be positioned 300mm-500mm from the well opening, but is not limited to this.

[0056] Furthermore, embodiments of this application also include a user water intake device 7, which includes a long-shaft submersible pump 71 and a water intake pipe 72. The long-shaft submersible pump 71 is disposed below the water surface of the collection well 1, and one end of the water intake pipe 72 is connected to the long-shaft submersible pump 71, while the other end leads out of the collection well 1. In embodiments of this application, water in the collection well 1 can be pumped to the user's water usage location through the user water intake device 7, realizing the recycling of wastewater from the integrated cyclone dust removal dry quenching boiler.

[0057] The integrated cyclone dust collector dry quenching boiler mainly consists of two parts: a cyclone primary dust collector and the integrated dry quenching boiler itself. The cyclone primary dust collector reduces the dust content and concentration in the boiler inlet circulating gas, while simultaneously lowering the flue gas temperature at the superheater of the integrated dry quenching boiler, thus protecting the superheater. The wastewater temperature generated by the integrated dry quenching boiler is maintained at a high temperature of 100-150℃, and the pressure is maintained between 0.2MPa and 0.6MPa.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
