Description

Technical Field

[0001] This application relates to the technical field of liquid fuel combustion experiments, and in particular to a liquid chemical mixing and combustion apparatus. Background Technology

[0002] The purpose of liquid combustion experiments is to study and evaluate the emissions of gaseous pollutants after the combustion of liquid fuels. By detecting the pollutants generated during the combustion process, the development and progress of environmental protection technologies can be promoted.

[0003] There are two common experimental methods. The first is to directly ignite and burn the liquid, and then take samples for testing to determine the gaseous pollutants after the liquid fuel combustion. In practical applications, fires caused by the combustion of liquid fuels are not caused by a single chemical as fuel, but by two or more chemicals. Different liquid fuels have differences in compatibility, density, polarity, etc. Directly adding multiple liquid fuels into the combustion chamber and stirring them will not only cause liquid phase stratification, which directly affects the homogeneity of the fuel mixture, but also cause the liquid fuel to volatilize during stirring, thereby reducing the combustion effect of the liquid and thus reducing the experimental results of the liquid combustion experiment.

[0004] The second method involves atomizing the liquid fuel before ignition to increase the contact area and improve the combustion effect. However, the atomized liquid fuel is in the form of aerosol particles, which is inconsistent with the initial state of the liquid fuel as the combustion source in actual combustion. This results in a difference between the state of the combustion flame and that in actual accidents, thus reducing the experimental effect of liquid combustion experiments. Summary of the Invention

[0005] To improve the experimental results of liquid combustion experiments, this invention provides a liquid chemical mixing and combustion device.

[0006] The liquid chemical mixing and combustion device provided in this application adopts the following technical solution:

[0007] A liquid chemical mixing and combustion device includes a combustion platform with a combustion chamber, a feeding assembly, an atomizing assembly, a conveying assembly, and a detection assembly disposed on the combustion platform. The combustion platform is also provided with a condensation chamber. The feeding assembly is used to convey liquid fuel to the atomizing assembly for atomization. The condensation chamber is used to mix and condense the atomized gas. The conveying assembly is used to convey the condensed liquid mixed fuel to the combustion chamber. The detection assembly is used to monitor and analyze the combustion flame.

[0008] By adopting the above technical solution, the liquid fuel is atomized and collected in the condensation chamber after passing through the feeding component and atomizing component. Multiple atomized fuels mix and condense into a mixed liquid phase in the condensation chamber. The conveying component delivers the mixed liquid fuel to the combustion chamber, where the operator ignites it. At the same time, the detection component monitors and analyzes the flame generated by the fuel. By atomizing and then re-liquefying the liquid fuel, the multiple atomized liquid fuels are uniformly mixed. The condensed mixed liquid is then delivered to the combustion platform for combustion, simulating the combustion state of mixed liquid fuels. This reduces the probability of stratification caused by direct mixing of multiple liquid fuels, thus improving the uniformity of mixing multiple liquid fuels and enhancing the experimental effect of liquid combustion experiments.

[0009] Optionally, the condensation chamber is conical, with its open end located above its narrow end. The atomizing component is connected to the open end of the condensation chamber, and the conveying component is connected to the narrow end of the condensation chamber.

[0010] By adopting the above technical solution, the atomized fuel mist enters the condensation chamber from the open end. Multiple mists mix in the condensation chamber, and the mixed mist diffuses downward from the top of the condensation chamber and gradually condenses into a liquid phase. Then, the liquid mixed fuel is directly transported to the combustion chamber through the conveying component. The conical design facilitates the collection and guidance of the mist, reducing the probability of a large amount of liquid phase remaining in the condensation chamber and volatilizing. This improves the uniformity and convenience of liquid fuel mixing, thereby improving the experimental effect of liquid combustion experiments.

[0011] Optionally, the feeding assembly includes:

[0012] Multiple storage tanks, wherein the multiple storage tanks are used to store multiple different liquid fuels separately;

[0013] The feed pipe is provided in multiple ways and corresponds one-to-one with the storage tank. The feed pipe is installed on the corresponding storage tank and connected to the atomizing component for conveying liquid fuel. The feed pipe is equipped with a flow meter with a valve.

[0014] By adopting the above technical solution, liquid fuel is added to different storage tanks, the valve is opened, and the liquid fuel is transported to the atomizing component through the feed pipe for atomization. The liquid flow rate is observed and controlled by a flow meter with a valve to achieve the fuel combustion ratio required by the researchers, thereby improving the mixing and combustion effect of the fuel and thus improving the experimental results of liquid combustion experiments.

[0015] Optionally, the atomizing component includes:

[0016] A high-pressure gas tank containing high-pressure inert gas;

[0017] The high-pressure nozzle is provided in multiple parts, each corresponding to a feed pipe. The high-pressure nozzle is located on the condensation chamber and extends downward into the condensation chamber at an angle. The high-pressure nozzle and its corresponding feed pipe are connected and connected to the high-pressure gas tank through a gas delivery pipe.

[0018] By adopting the above technical solution, the high-pressure gas tank is opened, and high-pressure gas enters the high-pressure nozzle through the gas delivery pipe. At the same time, liquid fuel enters the high-pressure nozzle through the feed pipe and mixes with the high-pressure gas. Under the action of the high-pressure gas, the liquid fuel is atomized and sprayed into the condensation chamber through the high-pressure nozzle. Multiple gas mists mix in the condensation chamber, which is under normal pressure. The mixed gas mists condense into a liquid phase and move down through the inner wall of the condensation chamber, eventually collecting at the bottom of the condensation chamber. The conveying component conveys the mixed liquid fuel, thereby realizing the atomization-liquefaction process of liquid fuel. This not only improves the convenience and uniformity of mixing multiple fuels, but also allows the fuel to return to a liquid state, which can better simulate the flame state in real accidents and is more valuable for reference. Therefore, it improves the experimental effect of liquid combustion experiments.

[0019] Optionally, the top of the storage tank is provided with an injection pipe, which is gooseneck shaped and communicates with the inner cavity of the storage tank for adding liquid fuel.

[0020] By adopting the above technical solution, the gooseneck-shaped injection pipe creates a non-airtight open environment inside the storage tank. Liquid fuel is transferred from the feed pipe to the corresponding high-pressure nozzle at a lower height through the principle of communicating vessels. The gooseneck design of the injection pipe reduces the probability of external impurities entering the storage tank and adversely affecting the liquid fuel, thus improving the experimental results of liquid combustion experiments.

[0021] Optionally, the conveying assembly includes:

[0022] A liquid pump, the inlet end of which is connected to the narrow end of the condensation chamber via a suction pipe;

[0023] A delivery pipe is provided at the outlet end of the liquid pump and communicates with the combustion chamber.

[0024] By adopting the above technical solution, the mixed gas mist condenses into a liquid phase and moves downward through the inner wall of the condensation chamber, eventually collecting at the bottom of the condensation chamber. The liquid pump is started to draw in the mixed fuel, which then enters the combustion chamber through the suction pipe and the delivery pipe. The operator can then ignite the fuel. By drawing in the mixed fuel that has condensed into a liquid phase and then igniting it, the probability of slow stratification of multiple liquid fuels is reduced, thereby improving the uniformity of the mixture of multiple liquid fuels and thus improving the experimental effect of liquid combustion experiments.

[0025] Optionally, the detection component includes:

[0026] A Fourier spectrometer is mounted on the combustion platform and used to analyze the combustion flame. The sampling port of the Fourier spectrometer is directly above the combustion chamber.

[0027] A data processing device, which is connected to a Fourier spectrometer and is used to process and analyze flame combustion spectra.

[0028] By adopting the above technical solution, the Fourier spectrometer can monitor, analyze and record the spectrum of the combustion flame in real time online, and the data processing system can be used to analyze the flame spectrum to achieve qualitative and quantitative analysis of the products after the combustion of liquid fuel.

[0029] Optionally, it also includes an igniter, which is provided with a ignition needle that extends into the combustion chamber.

[0030] By adopting the above technical solution, operators can ignite the liquid fuel in the combustion chamber by operating the igniter from a safe distance, thereby improving the safety of liquid combustion experiments.

[0031] Optionally, a background plate is provided on the combustion platform. The background plate is located behind the combustion chamber and facilitates observation of the flame combustion state.

[0032] By adopting the above technical solution, the background plate makes it easier to observe the shape and color of the flame combustion, thereby improving the experimental effect of liquid combustion experiments.

[0033] Optionally, the background plate is provided with scale lines to facilitate the measurement of flame height.

[0034] By adopting the above technical solution, the scale line is used to observe the height of the flame combustion, so as to record the combustion state of the liquid fuel, thereby improving the experimental effect of the liquid combustion experiment.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. Liquid fuel, after passing through the feeding and atomizing components, is in a gaseous state and collects in the condensation chamber. Multiple gaseous fuels mix and condense into a mixed liquid phase in the condensation chamber. The conveying component delivers the mixed liquid fuel to the combustion chamber, where the operator ignites it. Simultaneously, the detection component monitors and analyzes the flame produced by the fuel. By atomizing and then re-liquefying the liquid fuel, multiple atomized liquid fuels are uniformly mixed. The condensed liquid mixture is then delivered to the combustion platform for combustion, simulating the combustion state of mixed liquid fuels. This reduces the probability of stratification caused by direct mixing of multiple liquid fuels, thus improving the uniformity of mixing and enhancing the experimental results of liquid combustion experiments.

[0037] 2. The atomized fuel mist enters the condensation chamber from the open end. Multiple mists mix in the condensation chamber, and the mixed mist diffuses downward from the top of the condensation chamber and gradually condenses into a liquid phase. Then, the liquid mixed fuel is directly transported to the combustion chamber through the conveying component. The conical design facilitates the collection and guidance of the mist, reducing the probability of a large amount of liquid phase remaining in the condensation chamber and evaporating, thereby improving the uniformity and convenience of liquid fuel mixing.

[0038] 3. The mixed gas mist condenses into a liquid phase and moves downward through the inner wall of the condensation chamber, eventually collecting at the bottom of the condensation chamber. The liquid pump is started to draw in the mixed fuel. The mixed fuel enters the combustion chamber through the suction pipe and the delivery pipe. The operator can then ignite the fuel. By drawing in the mixed fuel that has condensed into a liquid phase and then igniting it, the probability of slow stratification of multiple liquid fuels is reduced, thereby improving the uniformity of the mixture of multiple liquid fuels.

[0039] 4. The graduated background board facilitates the observation of the shape, color, and height of the flame, making it easier to record the combustion state of liquid fuels and thus improving the experimental results of liquid combustion experiments. Attached Figure Description
