Description

Technical Field

[0001] This invention relates to the field of coal gasification combined cycle power generation, and more specifically, to a device for measuring the evaporation rate of slag water. Background Technology

[0002] As a core piece of equipment in large-scale energy conversion projects such as integrated gasification combined cycle (IGCC), coal chemical industry, and coal-to-oil and gasification, the performance of the gasifier directly affects the overall energy efficiency, environmental emission standards, and economic benefits of the project. In these projects, the gasifier employs liquid ash removal technology to ensure a high-temperature operating environment within the furnace and promote complete coal gasification. However, the high-temperature characteristics of the liquid ash removal process inevitably generate a large amount of water vapor. This water vapor further integrates into the process system, causing complex impacts on the gasifier's performance calculations, the elemental balance in the process, and the overall system water balance.

[0003] Existing technologies for handling heat loss from steam generation primarily rely on empirical estimations, treating heat loss as a fixed parameter in calculations. While simple, this approach has significant limitations. The estimation of heat loss often contains substantial errors and ignores the impact of coal quality variations and dynamic changes in gasifier operating conditions. Differences in coal quality, such as ash content, moisture content, and calorific value, significantly affect the thermal efficiency of the liquid slag discharge process. Furthermore, fluctuations in gasifier operating conditions, such as operating temperature, pressure, and the amount of gasifying agent used, directly influence both steam generation and heat loss. Summary of the Invention

[0004] The main objective of this invention is to provide a device for measuring the evaporation rate of slag water, in order to solve the problem in related technologies where the heat loss of water vapor generated during the liquid slag discharge process is estimated based on experience, resulting in a large error.

[0005] To achieve the above objectives, the present invention provides a device for measuring the evaporation rate of slag water, comprising: a slag quenching tank, the inner cavity of which forms a slag pool; a slag collecting tank, which is provided with a slag inlet pipe, a slag outlet pipe, a water supply pipe, and a water outlet pipe, the slag inlet pipe being connected to the slag pool of the slag quenching tank, and the water supply pipe being provided with a first thermometer and a first flow meter; a hydraulic circulator, which is connected to the water outlet pipe via a first connecting pipe and to the slag pool of the slag quenching tank via a second connecting pipe, the hydraulic circulator being provided with a slag discharge water pipe, and the slag discharge water pipe being provided with a second thermometer and a second flow meter; a cooler, which is connected to the second connecting pipe, and the cooler's water outlet pipe being provided with a third thermometer and a third flow meter; and a controller, wherein the first thermometer, the first flow meter, the second thermometer, the second flow meter, the third thermometer, and the third flow meter are all signal-connected to the controller.

[0008] Furthermore, the first support includes a housing covering the first thermometer and a heat insulation layer disposed between the housing and the first thermometer.

[0009] Furthermore, the heat insulation layer includes an outer reflective layer, an intermediate heat insulation layer, and an inner contact layer connected sequentially from the outside to the inside of the shell. The outer reflective layer is in contact with the inner wall of the shell, and the inner contact layer is in contact with the first thermometer.

[0010] Furthermore, the intermediate insulation layer is a hollow insulation board.

[0011] Furthermore, the device for measuring the evaporation of slag water also includes multiple second supports, each of which is installed on the outside of the first flow meter, the second flow meter, and the third flow meter.

[0012] Furthermore, the second bracket includes a horizontal plate fixed to the first flow meter and multiple support rods connecting the horizontal plate and the water supply pipe.

[0013] Furthermore, the first flow meter is fixed to the horizontal plate by a spring isolator.

[0014] Furthermore, the end of each support rod is positioned and connected to the water supply pipe via a locating pin.

[0015] According to the technical solution of this invention, the device for measuring the evaporation rate of slag water includes: a slag quenching tank, a slag collecting tank, a hydraulic circulator, a cooler, and a controller.

The hydraulic circulator is equipped with a slag discharge water pipe, and the slag discharge water pipe is equipped with a second thermometer and a second flow meter. The cooler is connected to the second connecting pipe, and the cooler's water outlet pipe is equipped with a third thermometer and a third flow meter.

[0027] like Figure 1As shown, this application provides a device for measuring the evaporation rate of slag water. An embodiment of the device includes: a slag quenching tank 10, a slag collection tank 20, a hydraulic circulator 30, a cooler 41, and a controller. The inner cavity of the slag quenching tank 10 forms a slag pool. The slag collection tank 20 is equipped with a slag inlet pipe 21, a slag outlet pipe 22, a water supply pipe 23, and a water outlet pipe 24. The slag inlet pipe 21 is connected to the slag pool of the slag quenching tank 10. The water supply pipe 23 is equipped with a first thermometer 51 and a first flow meter 52. The hydraulic circulator 30 is connected to the water outlet pipe 24 via a first connecting pipe 31 and to the slag pool of the slag quenching tank 10 via a second connecting pipe 32.

The first thermometer 51, the first flow meter 52, the second thermometer 53, the second flow meter 54, the third thermometer 55, and the third flow meter 56 are all connected to the controller signal.

[0028] The technical solution of an embodiment of the slag evaporation measurement device includes: a slag quenching tank 10, a slag collection tank 20, a hydraulic circulator 30, a cooler 41, and a controller. The inner cavity of the slag quenching tank 10 forms a slag pool. The slag collection tank 20 is equipped with a slag inlet pipe 21, a slag outlet pipe 22, a water supply pipe 23, and a water outlet pipe 24. The slag inlet pipe 21 is connected to the slag pool of the slag quenching tank 10, and the water supply pipe 23 is equipped with a first thermometer 51 and a first flow meter 52. The hydraulic circulator 30 is connected to the water outlet pipe 24 via a first connecting pipe 31 and to the slag pool of the slag quenching tank 10 via a second connecting pipe 32. The hydraulic circulator 30 is equipped with a slag discharge water pipe 33, and the slag discharge water pipe 33 is equipped with a second thermometer 53 and a second flow meter 54. Cooler 41 is connected to the second connecting pipe 32. A third thermometer 55 and a third flow meter 56 are installed on the outlet pipe 24 of cooler 41. The first thermometer 51, first flow meter 52, second thermometer 53, second flow meter 54, third thermometer 55, and third flow meter 56 are all connected to the controller signal. The first thermometer 51 and first flow meter 52 installed on the water supply pipe 23 can monitor the temperature and flow rate changes of the supply water in real time. The second thermometer 53 and second flow meter 54 installed on the slag discharge water pipe 33 can monitor the temperature and flow rate changes of the slag discharge water in real time. The third thermometer 55 and third flow meter 56 installed on the outlet pipe 24 of cooler 41 are used to monitor the temperature and flow rate changes of the cooling water. During the slag discharge process in the slag discharge water pipe 33, the controller can determine the evaporation rate and heat loss of the slag water based on the information transmitted by the first thermometer 51, first flow meter 52, second thermometer 53, second flow meter 54, third thermometer 55, and third flow meter 56, avoiding reliance on experience to estimate heat loss, which can lead to significant errors. Therefore, the technical solution of the embodiment of the slag water evaporation measurement device effectively solves the problem in the related technology that the water vapor generated in the liquid slag discharge process relies on experience to estimate the heat loss, which has a large error.

[0029] like Figure 1 As shown, a circulation pump 42 is installed on the first connecting pipe 31, and an analyzer 43 for analyzing the components in the slag discharge water pipe 33 is also installed on the slag discharge water pipe 33. The circulation pump 42 enhances hydraulic circulation, ensures the stability and circulation efficiency of the water flow, and helps in the calculation of energy balance. The analyzer 43 can monitor the components in the slag discharge water in real time, thereby more accurately assessing the evaporation and heat loss of the slag water and improving the accuracy of the measurement.

[0030] like Figure 1 As shown, the device for measuring the evaporation of sludge and water also includes multiple first supports, each of which is installed on the outside of the first thermometer 51, the second thermometer 53, and the third thermometer 55. The first supports are used to fix the thermometers, maintain their stability during the measurement process, and reduce the influence of external vibrations, thereby improving the accuracy and reliability of temperature measurement.

[0031] like Figure 1 As shown, the first support includes a housing covering the first thermometer 51 and a heat insulation layer disposed between the housing and the first thermometer 51. The housing provides physical protection to prevent damage to the thermometer, while the heat insulation layer reduces the influence of ambient temperature on the thermometer, ensuring the measurement accuracy of the thermometer in different environments.

[0032] like Figure 1 As shown, the insulation layer includes an outer reflective layer, an intermediate insulation layer, and an inner contact layer connected sequentially from the outside to the inside of the shell. The outer reflective layer is in contact with the inner wall of the shell, and the inner contact layer is in contact with the first thermometer 51. The outer reflective layer reflects external heat radiation, the intermediate insulation layer reduces heat conduction, and the inner contact layer is in close contact with the thermometer, which helps to quickly and accurately transmit the temperature of the medium, thus improving the insulation effect and the accuracy of temperature measurement.

[0033] like Figure 1 As shown, the intermediate insulation layer is a hollow insulation board. The hollow structure reduces heat conduction, improves insulation efficiency, and further enhances the accuracy of temperature measurement.

[0034] like Figure 1 As shown, the device for measuring the evaporation rate of sludge and water also includes multiple second supports, each of which is installed outside the first flow meter 52, the second flow meter 54, and the third flow meter 56. The second supports are used to fix the flow meters, maintain their stability during the measurement process, and reduce external interference, thereby improving the accuracy and reliability of the flow measurement.

[0035] like Figure 1 As shown, the second bracket includes a horizontal plate fixed to the first flow meter 52 and multiple support rods connecting the horizontal plate and the water supply pipe 23. The horizontal plate provides an installation platform for the flow meter, and the support rods fix the relative position of the flow meter and the pipeline, reducing measurement errors and improving the stability and measurement accuracy of the flow meter.

[0036] like Figure 1 As shown, the first flow meter 52 is fixed to the horizontal plate by a spring vibration isolator. The spring vibration isolator can absorb vibration, reduce the impact of pipeline vibration on the flow meter measurement accuracy, and improve the accuracy and stability of flow measurement.

[0037] like Figure 1 As shown, the end of each support rod is positioned and connected to the water supply pipe 23 via a locating pin. The locating pin ensures accurate alignment between the support rod and the pipe, further stabilizing the installation of the flow meter and improving the accuracy and reliability of flow measurement.

[0038] During the slag collection process, the slag from the gasifier enters the slag quencher. The molten slag first passes through the slag quencher (which requires water spraying to break up the molten slag) and is rapidly decomposed into small ash particles. The ash particles and ash water flow downward into the slag collection tank, which is mainly responsible for slag discharge to relieve pressure. The slag discharge port is used to discharge excess ash water, which is an intermittent discharge process.

[0039] The circulating pump 3 at the top of the slag collection tank pressurizes and sends the ash water into a hydrocyclone. After liquid-solid separation, the liquid (water) is separated out. After heat exchange in the cooler, it enters the slag quench tank 10 as a water source for spraying water to facilitate the breaking up of molten slag. After liquid-solid separation in the hydrocyclone, the solids and excess ash water are discharged through the slag discharge port.

[0040] The setup and coordination of the above-mentioned technical components have optimized the performance of the slag and water evaporation measurement device from different perspectives, improved the accuracy and reliability of temperature and flow rate measurements, reduced the influence of external environmental factors on the measurement results, and enabled accurate calculation of slag and water evaporation and heat loss. This effectively solves the error problem caused by relying on empirical estimation and provides more accurate data support for gasifier performance research and process optimization.

[0041] The technical solution of an embodiment of the slag evaporation measurement device includes: a slag quenching tank 10, a slag collection tank 20, a hydraulic circulator 30, a cooler 41, and a controller. The inner cavity of the slag quenching tank 10 forms a slag pool. The slag collection tank 20 is equipped with a slag inlet pipe 21, a slag outlet pipe 22, a water supply pipe 23, and a water outlet pipe 24. The slag inlet pipe 21 is connected to the slag pool of the slag quenching tank 10, and the water supply pipe 23 is equipped with a first thermometer 51 and a first flow meter 52. The hydraulic circulator 30 is connected to the water outlet pipe 24 via a first connecting pipe 31 and to the slag pool of the slag quenching tank 10 via a second connecting pipe 32. The hydraulic circulator 30 is equipped with a slag discharge water pipe 33, and the slag discharge water pipe 33 is equipped with a second thermometer 53 and a second flow meter 54. Cooler 41 is connected to the second connecting pipe 32. A third thermometer 55 and a third flow meter 56 are installed on the outlet pipe 24 of cooler 41. The first thermometer 51, first flow meter 52, second thermometer 53, second flow meter 54, third thermometer 55, and third flow meter 56 are all connected to the controller signal. The first thermometer 51 and first flow meter 52 installed on the water supply pipe 23 can monitor the temperature and flow rate changes of the supply water in real time. The second thermometer 53 and second flow meter 54 installed on the slag discharge water pipe 33 can monitor the temperature and flow rate changes of the slag discharge water in real time. The third thermometer 55 and third flow meter 56 installed on the outlet pipe 24 of cooler 41 are used to monitor the temperature and flow rate changes of the cooling water. During the slag discharge process in the slag discharge water pipe 33, the controller can determine the evaporation rate and heat loss of the slag water based on the information transmitted by the first thermometer 51, first flow meter 52, second thermometer 53, second flow meter 54, third thermometer 55, and third flow meter 56, avoiding reliance on experience to estimate heat loss, which can lead to significant errors. Therefore, the technical solution of the embodiment of the slag water evaporation measurement device effectively solves the problem in the related technology that the water vapor generated in the liquid slag discharge process relies on experience to estimate the heat loss, which has a large error.

[0042] like Figure 1 As shown, a circulation pump 42 is installed on the first connecting pipe 31, and an analyzer 43 for analyzing the components in the slag discharge water pipe 33 is also installed on the slag discharge water pipe 33.

The first supports are used to fix the thermometers, maintain their stability during the measurement process, and reduce the influence of external vibrations, thereby improving the accuracy and reliability of temperature measurement.

[0044] like Figure 1 As shown, the first support includes a housing covering the first thermometer 51 and a heat insulation layer disposed between the housing and the first thermometer 51. The housing provides physical protection to prevent damage to the thermometer, while the heat insulation layer reduces the influence of ambient temperature on the thermometer, ensuring the measurement accuracy of the thermometer in different environments.
