Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection equipment, in particular to an evaluation device for environmental pollution caused by textile incineration. Background Technique

[0002] At present, there are various testing methods, standards and instruments for the combustion performance of textiles at home and abroad. Most of them are for detecting the combustion behavior of the whole textile in a fire scene. The main technical solution is a cone calorimeter. This detection device uses a radiation cone for heating, and there are problems such as inaccurate temperature control, uneven heating of samples, and incomplete combustion. The bottom of the specimen box of the cone calorimeter is made of flame-retardant cotton, and the surface is a horizontally placed textile. However, when burning, the liquid-phase substances generated by the melting of the textile flow on the surface of the specimen box and are easy to overflow from the specimen box, and solidify and adhere to the outer surface of the specimen box at the end of combustion, making the specimen box not easy to clean. The rotary ignition needle of the cone calorimeter cannot automatically record the start time and end time of ignition, and still requires manual data recording. Since the burning speed of some textiles is relatively fast, there are large subjective errors in manual recording, and there are large deviations in the ignition time data. At the same time, the sample is easy to contaminate the rotary ignition needle during the ignition and combustion process, resulting in the need for regular cleaning. In addition, the existing flue gas analysis system can only analyze CO, CO2 and smoke generation during the combustion process, and there is no direct evaluation index for air pollutants, making it difficult to quantitatively reveal the impact of textile incineration on environmental pollution. Although the air quality detector can monitor the change of AQI during incineration, since the air quality detector monitors the comprehensive impact of various pollutants in the environment, it is difficult to accurately reflect the release of a single pollutant and is not suitable for the evaluation of environmental pollution caused by textile combustion.

[0003] There are a few existing patents for the evaluation of environmental pollution caused by textile incineration. The Chinese utility model patent with the application number 201821592061.1 and the utility model name of a textile combustion performance detection device designs an igniter with a continuous and stable combustion function and is equipped with a flue gas collection and analysis system. Based on the total samples collected during the overall combustion process, post-analysis and processing are carried out. There are differences between this patent and the present patent in terms of ignition method, combustion time calculation method, gas collection path and monitoring method. Specifically: this patent designs a slide rail, a crank and other components to make the igniter move and burn stably, ensuring that the flame is continuous and stable when the textile burns; through the design of a timing trigger, a spring and other components, the burning time of the textile is recorded to evaluate its combustion performance, but the measurement index cannot be directly used for the evaluation of environmental pollution, and it may be worn out after long-term use and has low repeatability; this patent designs a combustion chamber, an airbag and other components to collect the gas generated by textile combustion, avoiding pollution and being available for later analysis, but it cannot reflect the real-time change of the gas situation during the combustion process.

[0004] Therefore, there is an urgent need to design an evaluation device for the environmental pollution caused by textile incineration to solve the above problems, so as to provide technical reference for the sustainable development of textiles. Utility Model Content

[0020] Please refer to Figure 1 - Figure 2, An environmental pollution evaluation device for textile incineration provided by an embodiment of the present application includes a combustion chamber 1, on which are provided: a telescopic ignition mechanism 2, a flue gas delivery pipe 5, a flue gas collection mechanism 6, a component analyzer 7, a calculation module 8, and a filtration and purification mechanism 9. The telescopic ignition mechanism 2 is installed inside the combustion chamber 1; the input end of the flue gas delivery pipe 5 is connected to the top end of the combustion chamber 1; the flue gas collection mechanism 6 is arranged at the output end of the flue gas delivery pipe 5; the component analyzer 7 is installed on the flue gas delivery pipe 5 and is located above the flue gas collection mechanism 6; the calculation module 8 is connected to the flue gas collection mechanism 6, the telescopic ignition mechanism 2, and the component analyzer 7; the filtration and purification mechanism 9 is installed at the topmost end of the flue gas delivery pipe 5.

[0021] In the specific implementation process, it should be noted that when the telescopic ignition mechanism 2 inside the combustion chamber 1 is activated, its photoelectric sensor 3 monitors the fire on the surface of the textile. Once the fire is detected, the ignition contact 23 automatically touches the textile and generates an electric spark to complete ignition, while recording the start and end times of ignition. Subsequently, the flue gas generated by combustion is transported to the flue gas collection mechanism 6 through the flue gas delivery pipe 5. During this process, the component analyzer 7 analyzes the flue gas in real time and detects the gas component information in the flue gas using an infrared light source and a thermopile detector. The calculation module 8 is connected to the flue gas collection mechanism 6, the telescopic ignition mechanism 2, and the component analyzer 7, and is responsible for controlling the temperature parameters of the entire experimental process, collecting and processing the flue gas component data, calculating the Air Quality Index (AQI), and generating a detailed air quality chart. At the same time, the flue gas passes through the filtration and purification mechanism 9. The blower 10 in this mechanism provides power to enable the flue gas to pass through the pre-filter layer 13 to remove large particulate dust, then through the porous filter plate 14 to intercept fine particulate matter, the activated carbon adsorption layer 15 to adsorb harmful gases and odors, and finally the HEPA filter 16 to remove particulate matter above 0.3 microns, ensuring that the discharged air quality meets the environmental protection standards. The entire work process realizes the full-process monitoring and treatment from textile incineration, flue gas generation, component analysis to emission purification, providing reliable data support for evaluating the impact of textile incineration on environmental pollution.

[0022] In some examples, furthermore, the combustion chamber 1 is also equipped with: a heat insulation cover 4, a weighing platform 17, a heat insulation layer 18, a heating mechanism 19, and an inclined specimen box 20. The heat insulation cover 4 is arranged at the top end of the combustion chamber 1 and is connected to the flue gas delivery pipe 5; the weighing platform 17 is installed at the bottom end inside the combustion chamber 1; the heat insulation layer 18 is arranged at the top of the weighing platform 17; the heating mechanism 19 is arranged above the heat insulation layer 18. The heating mechanism 19 is an electromagnetic coil, and the electromagnetic coil is connected to the calculation module 8; the bottom end of the inclined specimen box 20 is movably arranged at the top of the heating mechanism 19 through a slide rail. The bottom end of the inclined specimen box 20 is provided with a square depression, and the edge part is provided with an inclined surface that slopes towards the middle.

[0023] In the specific implementation process, it should be noted that the heat insulation cover 4 covers the top of the combustion chamber 1 and is connected to the flue gas delivery pipe 5 to prevent heat dissipation and ensure the temperature stability during the combustion process. The weighing platform 17 is installed at the bottom inside the combustion chamber 1 and is used to measure the mass change of the sample before and after combustion, so as to evaluate the combustion efficiency. An insulating layer 18 is laid above the weighing platform 17, with a specification of 100*100*20 mm, which effectively blocks heat transfer and ensures the accuracy of instrument measurement. The heating mechanism 19 is located above the insulating layer 18 and is internally provided with an electromagnetic coil wound in a 100*100 mm size. Through the electromagnetic induction heating circuit, the bottom overall area is heated to ensure uniform heating. The heating mechanism 19 is connected to the calculation module 8 and can set specific heating temperature parameters according to experimental requirements for digital control, so that the combustion temperature can be accurately adjusted within the range of 350-900 °C. The inclined sample box 20 is arranged at the top of the heating mechanism 19 and is connected to the heating mechanism 19 through a slide rail. Its specification is 100*100*25 mm, the upper surface descends 5 mm, the bottom is a square depression of 59*59 mm, and the edge part is provided with an inclined surface inclined towards the middle, which has a loading capacity and effectively prevents the liquid-phase substances generated during the combustion process from flowing out. The design of the inclined sample box 20 enables the sample to be uniformly heated during the combustion process, thus ensuring the accuracy of the experimental results. The working process of the entire combustion chamber 1 covers the heat preservation of the combustion environment by the heat insulation cover 4, the weight monitoring of the weighing platform 17, the temperature guarantee of the insulating layer 18, the precise temperature control of the heating mechanism 19, and the sample placement and combustion process of the inclined sample box 20, jointly ensuring the accuracy and reliability of the evaluation of the environmental pollution of textile incineration.

[0024] In some examples, furthermore, the telescopic ignition mechanism 2 includes: an electrical signal transmission rod 21, a telescopic rod 22, an ignition contact 23 and a photoelectric sensor 3. The electrical signal transmission rod 21 is arranged at the bottom inside the combustion chamber 1; one end of the telescopic rod 22 is fixedly installed on the outer side of the outer wall of the electrical signal transmission rod 21; the ignition contact 23 is rotatably arranged at the other end of the telescopic rod 22 through a hinge; the photoelectric sensor 3 is surrounded by the inner side of the heat insulation cover 4 and is located directly above the inclined sample box 20.

[0025] In the specific implementation process, it should be noted that the photoelectric sensor 3 is surrounded by the inner side of the heat insulation cover 4. It is a sensing mechanism with a built-in photodiode amplification circuit, which can sensitively detect whether there is a fire on the burning surface of the textile. According to the appearance and extinction of the fire, it sends signals to the electrical signal transmission rod 21 at the moment of the appearance and extinction of the fire, automatically recording the start and end times of ignition; the telescopic rod 22 is connected to the electrical signal transmission rod 21, with a length of 80 mm, and can reach the center of the sample fabric. It is composed of a supportive flame-retardant material. The ignition is carried out by means of electric spark contact ignition. When receiving the electrical signal at the moment of generating a fire, it automatically contracts, thus effectively preventing the ignition contact 23 from adhering to the textile and causing damage to the instrument; the ignition contact 23 is composed of two 1-cm-long metal rods, which are connected to the telescopic rod 22 through a hinge and can rotate freely by nearly 360 degrees. When the ignition contact 23 hangs naturally, the bottom end just touches the center of the bottom of the sample box when placing the fabric.

[0026] The ignition contact 23 is composed of two 1-cm-long metal rods, which are connected to the end of the telescopic rod 22 through a hinge and can rotate freely by nearly 360 degrees. When the photoelectric sensor 3 detects a fire signal, the telescopic rod 22 receives the electrical signal and quickly automatically contracts, thus moving the ignition contact 23 away from the sample surface, effectively preventing the ignition contact 23 from adhering to the textile and avoiding damage to the instrument.

[0027] In some examples, furthermore, the flue gas collection mechanism 6 is also equipped with an analog signal voltage sample comprehensive collector, an analog signal sampling module, an analog-to-digital converter, and a digital signal processing module. The analog signal voltage sample comprehensive collector is responsible for capturing information on the gases and particulate matter generated after combustion. Through the analog signal sampling module, this collector can accurately capture the analog voltage signals in the circuit to ensure the accuracy and integrity of the data. Subsequently, the analog-to-digital converter (ADC) converts these analog signals into digital signals, facilitating subsequent digital signal processing. The component analyzer 7 uses an infrared light source carbon silicon rod to emit infrared light, and the infrared light interacts with the gas through a glass gas chamber. This interaction causes changes in the characteristics of the infrared light, thus reflecting information on the gas components. Subsequently, the thermopile detector receives the infrared light passing through the gas chamber and converts it into an electrical signal for subsequent analysis.

[0028] In some examples, furthermore, the calculation module 8 includes a digital signal processing module and an AQI calculation module. The digital signal processing module further processes the converted digital signals, classifying and identifying the signals through advanced algorithms and technologies. The processed digital signals will be transmitted to the component analyzer 7 for a more in-depth analysis of the flue gas components. The AQI calculation module calculates the air quality index (AQI) based on the real-time monitored data and generates an air quality chart for each moment, as well as detailed information such as the content and yield of harmful gases and particulate matter.

[0029] In some examples, furthermore, the filtration and purification mechanism 9 includes: a filtration box, a blower 10, a sensor 12, a pre-filter layer 13, a porous filter plate 14, an activated carbon adsorption layer 15, and a HEPA filter 16. The filtration box is arranged at the output end of the flue gas delivery pipe 5; the blower 10 is installed at the end of the filtration box, and a wind speed regulator 11 is also installed on the blower 10; the sensor 12 is composed of a pressure sensor and a temperature sensor, and is respectively installed below the filtration box and inside the flue gas delivery pipe 5; the pre-filter layer 13, the porous filter plate 14, the activated carbon adsorption layer 15, and the HEPA filter 16 are arranged inside the filtration box in sequence from inside to outside.

[0030] In the specific implementation process, it should be noted that a filtration box is installed at the output end of the flue gas delivery pipe 5, and a blower 10 is installed at the end of the filtration box to provide power for the entire filtration system and ensure that the gas passes through the filter layer smoothly. A wind speed regulator 11 is set at the outlet of the blower 10 to adjust the wind speed as needed to meet the requirements of different processing capacities. Monitoring devices such as a pressure sensor 12 and a temperature sensor 12 are installed to monitor the operating status of the filtration system in real time. When an abnormality occurs, such as filter layer blockage, too high temperature, etc., the system should be able to automatically alarm and take corresponding treatment measures. The pre-filter layer 13 is a coarse filter screen made of nylon mesh to remove large particle dust and impurities and protect the subsequent filter layers. The porous filter plate 14 is located behind the pre-filter layer 13 and is made of a polymer material with uniformly distributed tiny holes, which can intercept fine particles and further improve the filtration efficiency. An activated carbon adsorption layer 15 is set behind the porous filter plate 14 to adsorb harmful gases and odors, such as sulfur dioxide, nitrogen oxides, volatile organic compounds (VOCs), etc. The HEPA (High Efficiency Particulate Air) filter, as the last line of defense, is made of a high-efficiency filter material and can remove particles above 0.3 microns to ensure that the discharged air quality meets the environmental protection standards.

[0031] Through the self-shape of the inclined test sample box 20, the textile incineration environmental pollution evaluation device effectively increases the load capacity, prevents the outflow of liquid-phase substances, thereby avoiding the pollution of the outer surface of the test sample box by liquid-phase residues and simplifying the cleaning process.

[0032] The design of combining a retractable ignition device with a photoelectric sensor 3 is adopted. The photoelectric sensor 3 detects whether there is a fire on the combustion surface of the textile and transmits an electrical signal to the retractable ignition device in real time to realize the automatic removal of the igniter, ensuring the accurate recording of the ignition time and reducing human error.

[0033] The flue gas collection mechanism 6 captures the flue gas samples during textile incineration. The component analysis system uses chemical analysis instruments to analyze the components of the flue gas samples. The AQI calculation module combines the pollutant concentration and the AQI model to calculate the AQI value of the incineration process in real time, and displays the AQI and other data in numbers and charts, facilitating the user to understand the incineration situation. It can store data in a timely manner and support the user to query historical data. This device realizes the comprehensive monitoring and in-depth analysis of the post-combustion gases and particulate matters, and provides scientific and accurate data support for evaluating the specific impact of textile combustion on environmental pollution.

For those skilled in the art, various changes and modifications can be made to the present application.
