Abstract
Description
Technical Field
[0001] This application relates to the technical field of coal quality analysis and detection, and specifically relates to a coal quality analysis system facilitating waste gas treatment. Background Art
[0002] Coal quality analysis is a series of testing and analysis methods for evaluating the properties and quality of coal. The purpose of coal quality analysis is to determine the composition, properties, and combustion characteristics of coal, including the quality, composition, calorific value, ash content, sulfur content, moisture content, volatile content, fixed carbon content, etc. When conducting elemental analysis and detection of coal quality, it is necessary to carry out high-temperature reactions of coal with oxygen in a heating furnace. This reaction is usually called coal combustion or gasification, and its purpose is to convert the chemical components in coal into gases for subsequent analysis. By burning the coal sample in the heating furnace, gases containing various elements in the coal can be generated. These gases can be analyzed by spectroscopic or non-spectroscopic methods to determine the chemical composition of coal, such as the content of elements like carbon, hydrogen, nitrogen, sulfur, etc.; and various gases are released during the coal combustion process, including carbon monoxide, carbon dioxide, sulfides, etc. By analyzing the composition and concentration of these gases, the combustion efficiency of coal, the types and concentrations of pollutants generated during combustion can be understood, and then the combustion characteristics of coal can be evaluated; in addition, coal may contain harmful elements such as sulfur and nitrogen, and these elements will be converted into harmful gases such as sulfur dioxide and nitrogen oxides during the combustion process. By burning the coal sample in the heating furnace and detecting the generated gases, the content of harmful substances in coal can be determined. However, the gases generated by burning the coal sample in the heating furnace are not all used for analysis and detection by the analysis equipment, and the remaining gases in the heating furnace cannot be treated. Directly discharging them into the air is likely to cause air pollution and affect the environment. Summary of the Utility Model
[0003] Aiming at the deficiencies existing in the prior art, the purpose of this application is to provide a coal quality analysis system facilitating waste gas treatment to solve the problems raised in the above background art.
[0004] According to one aspect of the present application, a coal quality analysis system facilitating waste gas treatment includes a heating furnace, a storage tank for samples to be detected, an analysis device, and a waste gas treatment device. The heating furnace is connected to the analysis device through a main gas pipeline, and a storage tank for samples to be detected is provided on the main gas pipeline between the heating furnace and the analysis device. The storage tank for samples to be detected is used for temporarily storing the gas to be detected generated by burning coal samples in the heating furnace. A solenoid valve I is installed on the main gas pipeline between the storage tank for samples to be detected and the heating furnace. A suction pump I and a solenoid valve III are installed on the main gas pipeline between the storage tank for samples to be detected and the analysis device, and the suction pump I is arranged close to the storage tank for samples to be detected. A waste gas treatment device is externally connected to the main gas pipeline between the heating furnace and the solenoid valve I through a branch gas pipeline. A solenoid valve II is installed on the branch gas pipeline. An air outlet pipeline is further connected to the waste gas treatment device, and a suction pump II is installed at the connection position between the air outlet pipeline and the waste gas treatment device. A purification device is further provided on the air outlet pipeline.
[0005] Preferably, a dryer is installed at the top inside the storage tank for samples to be detected, and a gas pressure sensor is installed at the bottom inside the storage tank for samples to be detected.
[0006] Preferably, the waste gas treatment device includes a treatment tank, a sprayer, an activated carbon filter plate, a drain pipe, and a waste water collection tank. One side of the treatment tank is communicated with the branch gas pipeline, and the other side of the treatment tank is communicated with the air outlet pipeline. A sprayer is installed at the top inside the treatment tank, and a plurality of spray heads are arranged on the sprayer. Each spray head is arranged towards the inside of the treatment tank. The sprayer is externally connected to a water pump for water supply. A drain pipe is communicated with the bottom inside the treatment tank, and a waste water collection tank is arranged at the water outlet of the drain pipe. An activated carbon filter plate is fixedly arranged at a position close to the air outlet pipeline inside the treatment tank.
[0007] Preferably, the drain pipe is of a funnel-shaped structure and is arranged directly below the sprayer.
[0008] Preferably, a purification device is further provided on the air outlet pipeline.
[0009] The advantages of this application compared with the prior art are as follows: For a coal quality analysis system facilitating waste gas treatment in this application, by arranging a storage tank to be detected on the main gas pipeline between the heating furnace and the analysis equipment and arranging a waste gas treatment device on the branch gas pipeline, during the analysis and detection process, the gas generated by the combustion of the coal sample in the heating furnace is first transported to the storage tank to be detected through the main gas pipeline for temporary storage, so as to avoid directly entering the analysis equipment and causing excessive gas concentration to affect the detection result. Moreover, the gas can also be pretreated before gas analysis and detection in the storage tank to be detected to ensure the accuracy of gas analysis and detection by the analysis equipment. Then, when the gas in the storage tank to be detected is too much and causes excessive gas pressure in the tank, the excess gas in the heating furnace can enter the treatment tank of the waste gas treatment device through the branch gas pipeline. The gas is cooled, dust-removed, and some harmful gases are adsorbed by the sprayer, and the formed waste water can be discharged through the drain pipe and collected in the waste water collection tank. Then, the gas after spray treatment in the treatment tank is discharged after the adsorption and purification by the activated carbon filter plate, thus avoiding that the excess gas in the heating furnace is directly discharged into the air, which is likely to cause air pollution and affect the environment.

[0013] As Figure 1As shown in the figure, a coal quality analysis system for facilitating waste gas treatment includes a heating furnace 1, a storage tank 2 to be tested, an analysis device 3, and a waste gas treatment device 4. The heating furnace 1 is connected to the analysis device 3 through a main gas pipeline 5, and a storage tank 2 to be tested is arranged on the main gas pipeline 5 between the heating furnace 1 and the analysis device 3. The storage tank 2 to be tested is used to temporarily store the gas to be tested generated by burning coal samples in the heating furnace 1. When the analysis device 3 conducts analysis and detection, it is usually necessary to conduct multiple analyses and detections on the gas generated by burning coal samples in the heating furnace 1 to ensure the accuracy of the analysis and detection results. The setting of the storage tank 2 to be tested enables the gas generated by coal sample combustion to be temporarily stored in the storage tank 2 to be tested first when the analysis device 3 conducts one analysis and detection on the gas, facilitating the subsequent detection and analysis of the gas by the analysis device 3. In addition, a dryer 13 is installed at the top inside the storage tank 2 to be tested, and a gas pressure sensor 14 is installed at the bottom inside the storage tank 2 to be tested. The setting of the dryer 13 can dry the gas to be tested to avoid the water vapor in the gas affecting the detection results of the analysis device 3. The setting of the gas pressure sensor 14 can monitor the gas pressure inside the storage tank 2 to be tested to avoid danger caused by excessive air pressure value inside the storage tank 2 to be tested. An electromagnetic valve 6 is installed on the main gas pipeline 5 between the storage tank 2 to be tested and the heating furnace 1. The setting of the electromagnetic valve 6 can control the flow and blockage of the gas leading to the storage tank 2 to be tested and the analysis device 3. An air extraction pump 7 and an electromagnetic valve 3 are installed on the main gas pipeline 5 between the storage tank 2 to be tested and the analysis device 3, and the air extraction pump 7 is arranged close to the storage tank 2 to be tested. The setting of the air extraction pump can provide the power for the gas to lead to the storage tank 2 to be tested and the analysis device 3. The setting of the electromagnetic valve 8 can control the flow and blockage of the gas to be tested inside the storage tank 2 to be tested leading to the analysis device 3. A waste gas treatment device 4 is externally connected to the main gas pipeline 5 between the heating furnace 1 and the electromagnetic valve 6 through a branch gas pipeline 9, and an electromagnetic valve 10 is installed on the branch gas pipeline 9. The setting of the electromagnetic valve 10 can control the flow and blockage of the excess gas inside the heating furnace 1 leading to the waste gas treatment device 4.Specifically, the waste gas treatment device 4 includes a treatment tank 41, a sprayer 42, an activated carbon filter plate 43, a drain pipe 44, and a waste water collection tank 45. One side of the treatment tank 41 is connected to the gas distribution pipeline 9, and the other side of the treatment tank 41 is connected to the gas outlet pipeline 11. An air extraction pump two 12 is installed at the connection position of the gas outlet pipeline 11 and the treatment tank 41. The setting of the air extraction pump two 12 can provide the power for the excess gas in the heating furnace 1 to flow into the treatment tank 41. Moreover, a purification device 15 is also provided on the gas outlet pipeline 11, and the purification device 15 can further purify the gas. The sprayer 42 is installed at the top inside the treatment tank 41. The sprayer 42 is provided with a plurality of spray heads 421, and each spray head 421 is arranged towards the inside of the treatment tank 41. The sprayer 42 is externally connected to a water pump for water supply. The spray heads 421 on the sprayer 42 can cool down the gas, reduce dust, and adsorb some harmful gases. The drain pipe 44 is communicated with the bottom inside the treatment tank 41. The drain pipe 44 is of a funnel-shaped structure and is arranged directly below the sprayer 42. A waste water collection tank 45 is provided at the water outlet of the drain pipe 44, so that the waste water generated by the sprayer 42 can be discharged and collected into the waste water collection tank 45. An activated carbon filter plate 43 is fixedly provided at a position on one side of the treatment tank 41 close to the gas outlet pipeline 11, and the activated carbon filter plate 43 can adsorb and purify the gas after spray treatment.;
[0014] Working principle: During the analysis and detection process, at the beginning, solenoid valve 6, air extraction pump 7, and solenoid valve 8 are all opened, and solenoid valve 10 is closed. At this time, the gas generated by the combustion of the coal sample in the heating furnace 1 can be transported through the main gas pipeline 5 to the storage tank 2 to be detected, and then transported through the storage tank 2 to the analysis equipment 3 for a primary analysis and detection. When the analysis equipment 3 is performing the analysis and detection, solenoid valve 8 is closed. The storage tank 2 to be detected temporarily stores the gas to be detected under the action of the air extraction pump 7. When the gas pressure sensor 14 in the storage tank 2 to be detected detects that the pressure value exceeds the threshold, solenoid valve 10 and air extraction pump 12 are opened, and the excess gas in the heating furnace 1 is transported through the branch gas pipeline 9 to the treatment tank 41 of the waste gas treatment device 4, so as to reduce the flow rate of the gas flowing into the storage tank 2 to be detected, so as to avoid excessive gas pressure in the storage tank 2 to be detected. The excess gas in the heating furnace 1 enters the treatment tank 41, and the water flow sprayed by the spray head 421 of the sprayer 42 cools, dusts, and adsorbs some harmful gases on the gas, and the formed waste water can be discharged through the drain pipe 44 and collected into the waste water collection tank 45. Then, the gas after the spray treatment in the treatment tank 41 is discharged after being adsorbed and purified by the activated carbon filter plate 43, thus avoiding the air pollution caused by the direct discharge of the excess gas in the heating furnace 1 into the air and affecting the environment. When the analysis equipment 3 finishes the primary analysis and detection of the gas and needs to perform a secondary analysis and detection, solenoid valve 8 is opened, and solenoid valve 10 and air extraction pump 12 are closed, so that the gas to be detected in the storage tank 2 to be detected is transported to the analysis equipment 3 again for analysis and detection, and the gas generated by the combustion of the coal sample in the heating furnace 1 is detected multiple times according to the above steps to ensure the accuracy of the analysis and detection results. In addition, when the analysis equipment 3 needs to analyze and detect the dry gas, the dryer 13 in the storage tank 2 to be detected can heat and dry the gas to be detected.
