AI Technical Summary
[0003]传统的煤灰含碳量在线检测方法主要有灼烧失重法,是通过对灼烧前后所称得的重量损失信号进行计算,得到灰样的含碳量,具有精度高、样品用量少等优点,但由于需要加热和称重等过程,对灰样的代表性要求高、分析滞后,难以快速反映锅炉燃烧状况
[0021] In this invention, the storage component moves towards the detection body. After the inlet nozzle on the storage component is inserted into the through hole, the through groove on the rotating component rotates to coincide with the through hole. Then, under the action of the pressurizing component, the coal ash sample to be detected is sprayed at high speed into the detection tank through the through groove, so that the coal ash sample is evenly and rapidly diffused in the detection tank. This makes the detection of high-speed particles more comprehensive during the detection process, improves the detection efficiency, and avoids the trouble of waiting for reaction time in the combustion detection method. As the drive motor rotates forward and backward, the inlet nozzle on the storage component can move back and forth under the detection body. Each time it approaches, it detects coal ash on one side and transmits detection information on the other side. This ensures that the device can perform regular and quantitative coal ash sample testing, so that users can continuously change the air-coal ratio in the boiler based on the detection information.

Abstract
Description
Technical Field
[0001] This invention relates to the field of thermal power plant testing technology, specifically to a rapid carbon element determination device and method. Background Technology
[0002] Carbon content testing in thermal power plants is primarily used to determine the carbon content in coal ash, raw coal, or other raw materials and waste. Coal ash refers to the fine dust particles carried in the flue gas produced by fuel combustion. Excessive carbon content in coal ash indicates incomplete combustion of coal within the power plant, resulting in lower boiler combustion efficiency. Detecting the carbon content in coal ash allows power plants to adjust the coal-air mixture ratio based on the test results, ensuring more complete combustion and improving boiler combustion efficiency.
[0003] Traditional online methods for detecting carbon content in coal ash mainly include the loss-on-ignition method, which calculates the carbon content of the ash sample by analyzing the weight loss signals obtained before and after ignition. This method offers advantages such as high accuracy and small sample size. However, due to the need for heating and weighing, it requires high representativeness of the ash sample and suffers from analytical lag, making it difficult to quickly reflect the boiler combustion status. To improve the speed of carbon detection, activation analysis is generally used. Activation analysis involves bombarding the sample with neutrons, charged particles, or high-energy gamma photons of a certain energy and flux to activate the atoms to be measured. Then, the delayed radiation emitted during the decay of radioactive nuclides generated by the nuclear reaction is measured, or the instantaneous radiation emitted during the nuclear reaction is directly measured, thus achieving qualitative and quantitative analysis of nuclides and elements. However, activation analysis has its limitations.
[0004] Based on this, the present invention designs a rapid carbon element determination device and method to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a rapid carbon element determination device and method, so that coal ash can be diffused as much as possible in the detection area of activation analysis, thereby increasing the contact between particles and the sample and improving the detection efficiency of coal ash.

A half-width gear 20 is fixedly mounted on the lower end of the lower connecting shaft 21. The teeth of the half-width gear 20 mesh with the positioning gear 23.
[0035] Among them, the upper connecting shaft 18 is fixedly installed with a transition gear 17 at the end away from the active bevel gear 19, and the two sides of the detection body 1 are rotatably installed with transmission gears 16 corresponding to the positions of the transition gears 17.

[0039] In this invention, during the detection process, the drive motor drives the upper connecting shaft 18 to rotate.

The rotation of the transition gear 17 drives the transmission gear 16 meshing with it to rotate. The rotation of the transmission gear 16 drives the intermediate gear 15 to rotate.

The teeth of the half-amplitude gear 20 can drive the positioning gear 23 to rotate. The rotation of the positioning gear 23 drives the opening and closing gear 26 to rotate through the fixed wheel 24 and the limiting belt 25. The rotation of the opening and closing gear 26 interacts with the left tooth plate 9. Interacting with the right toothed plate 10, the storage components 4 on both sides are driven to move towards the detection body 1. When the inlet nozzle 11 on the storage component 4 is introduced into the through hole 14, the smooth surface of the half-width gear 20 begins to contact the positioning gear 23. Then, the through groove 32 on the rotating component rotates to the position that coincides with the through hole 14. Under the action of the pressure component 5, the coal ash sample to be detected is sprayed at high speed through the through groove 32 into the detection tank 30, so that the coal ash sample is evenly and rapidly diffused in the detection tank 30. This makes the detection of high-speed particles more comprehensive during the detection process, improves the detection efficiency, and avoids the trouble of waiting for reaction time in the combustion detection method. As the drive motor rotates continuously in both directions, the inlet nozzle 11 on the storage component 4 can move back and forth under the detection body 1. Each time it approaches, it performs coal ash detection on one side and transmits detection information on the other side. This ensures that the device can perform regular and quantitative coal ash sample testing, so that users can continuously change the air-coal ratio in the boiler based on the detection information.
