Description

Technical Field

[0001] This invention belongs to the field of burner technology, and in particular relates to a highly integrated standard burner test bench. Background Technology

[0002] Internal combustion engines, as high-efficiency, high-power-density power machines, have been used by humans for over a century and are currently the primary power source for automobiles and ships. They also have wide applications in agricultural equipment, construction machinery, and power plants. In-cylinder combustion in internal combustion engines is a high-temperature, high-pressure, and highly turbulent spray combustion process, influenced by numerous factors affecting soot formation and evolution. Furthermore, due to the enclosed nature of the combustion chamber and the transient nature of the combustion reaction, the in-cylinder combustion process is difficult to accurately capture. The repeatability of combustion experiments highly depends on the manufacturing precision of the burner system, the experimental environment, and the precision of controlling boundary conditions such as airflow rate and temperature / humidity. Traditional laboratory flame flow meters and temperature control devices are connected to the burner via external wiring, resulting in a high failure rate, especially causing severe corrosion to the flow meters. In addition, changes in ambient temperature and humidity also affect the boundary conditions of the combustion flame, ultimately impacting the accuracy of experimental results and hindering the development of combustion models and related academic exchanges.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] like Figures 1 to 3 The diagram shows a highly integrated standard burner test bench, which includes a burner 1 and an outer housing 2, with the burner 1 mounted at the rear end of the outer housing 2;

[0050] The right side of the outer casing 2 is a control panel, which is used to control the use of internal components, the display of each dial in this invention, the installation of switches, and the indication display, etc.

[0051] The flow regulating component 3 is installed at the front end inside the outer casing 2;

[0052] An alarm component 4 is installed at the rear end of the outer casing 2;

[0053] An air switch 5 is installed at the rear end inside the outer casing 2;

[0054] The front end of the right side face of the outer casing 2 is evenly distributed with first mounting slots 21, and a temperature display 22 is fixedly installed in the first mounting slots 21.

[0055] Rotary buttons 23 are evenly distributed on the front end of the right side of the outer casing 2;

[0056] The rotary knob 23 is located at the front of the temperature display 22;

[0057] An ammeter 24 and a voltmeter 25 are respectively installed on the center of the right side of the outer casing 2;

[0058] By setting up a temperature display 22, an ammeter 24 and a voltmeter 25, etc., the normal operation of each internal component can be intuitively displayed through data visualization.

[0059] Air switch 5 is used to cut off power supply when the current exceeds the critical current, thus protecting the highly integrated standard burner test bench.

[0060] like Figure 4 To the diagram Figure 9 As shown, the flow regulating component 3 includes a plurality of flow meters 31 arranged in a linear array and a first connecting pipe 32 connecting both ends of the flow meters 31. The end of the first connecting pipe 32 away from the flow meters 31 is connected to a spare pipe assembly 33.

[0061] Both the front and rear ends of the first connecting pipe 32 are connected to pipe cleaning and anti-corrosion components 34.

[0062] The backup piping assembly 33 includes a first tee pipe 331 and a first segmented extension pipe 332 connected to both ends of the tee pipe;

[0063] The first tee pipe 331 includes a main pipe 333 and two branch pipes 334 connected to the main pipe 333. The end of the main pipe 333 away from the branch pipes 334 is connected to the first connecting pipe 32, and the end of the branch pipes 334 away from the main pipe 333 is connected to the first segmented extension pipe 332.

[0064] The first segment extension pipe 332 is provided with a second segment extension pipe 335 at the end away from the branch pipe 334, and a filter separation pipe 336 is connected between the first segment extension pipe 332 and the second segment extension pipe 335.

[0065] The end of the second segment extension pipe 335 away from the filter separation pipe 336 is fixedly connected to the second three-way pipe 337, and the second three-way pipe 337 is symmetrically arranged with the first three-way pipe 331.

[0066] A first control valve 3321 is installed on the first segment extension pipe 332;

[0067] A second control valve 3351 is installed on the second segment extension pipe 335;

[0068] A filter layer 338 is installed inside the filter separator tube 336;

[0069] Both ends of the filter separator tube 336 are fitted with sealing layers 3361;

[0070] The sealing layers 3361 at both ends are commonly used pipe sealing connectors, which are installed on the outside of the first segment extension pipe 332 and the second segment extension pipe 335 respectively, for connecting the pipes.

[0071] With this setup, two T-pipes are provided, namely the second T-pipe 337 and the first T-pipe 331, so that when one pipe is blocked, the other pipe can be switched to for use without affecting the operation.

[0072] It is equipped with a filter layer 338, which is a gas filter used for drying the gas in the pipeline and for preliminary filtration of gas impurities.

[0073] The outer casing 2 has second mounting slots 26 evenly distributed on the rear end of the right side of the outer casing 2, and a flow display 27 is fixedly installed in the second mounting slots 26.

[0074] The flow display 27 is used to display the data of the flow meter 31. It is connected to the flow meter 31. This setting can display the gas flow in different pipelines in real time and adjust the gas flow.

[0075] The pipeline cleaning and corrosion protection component 34 includes a vertically connected vertical pipe 341 and a horizontal pipe 342, and a third control valve 343 is installed on the horizontal pipe 342.

[0076] Two rows of first clean gas storage tanks 28 and second clean gas storage tanks 29 are placed at the lower end of the outer casing 2. The end of the horizontal tube 342 away from the vertical tube 341 is connected to the first clean gas storage tank 28.

[0077] After long-term use, the flow meter suffers from severe internal corrosion due to the difficulty of internal cleaning, which affects the measurement accuracy of the flow meter and greatly shortens its service life.

[0078] With this setup, after the flow meter is used, a cleaning gas that can react and clean the original reacting gas can be stored in the first cleaning gas storage tank 28 according to the different original reacting gases inside. This cleaning gas is then introduced into the first connecting pipe 32 through the vertical pipe 341 and the horizontal pipe 342 to clean the inside of the flow meter 31. After cleaning, dry air is introduced into the flow meter 31 through the second cleaning gas storage tank 29 to ensure that the flow meter 31 is clean and dry when not in use. This effectively protects the flow meter 31, slows down the corrosion rate inside the flow meter 31, and thus extends the service life of the flow meter 31 while ensuring its accuracy.

[0079] like Figures 10 to 13 As shown, the alarm component 4 includes a rectangular outer housing 41 and an alarm 42 installed inside the front end of the rectangular outer housing 41. A controller 43 is installed inside the rear end of the rectangular outer housing 41.

[0080] The rectangular outer shell 41 has edge protective plates 411 attached to both the left and right ends;

[0081] An emergency stop button 6, a switch button 7, and an indicator light 8 are respectively installed on the lower right side of the outer casing 2;

[0082] A protective disc 61 is fixedly installed on the right end of the emergency stop button 6;

[0083] The right side of the protective disc 61 is curved;

[0084] An eccentric wheel 62 is tightly placed at the lower right end of the protective disc 61. A connecting shaft 621 is fixedly installed at the upper rear side of the eccentric wheel 62. A motor 622 is electrically connected to the rear end of the connecting shaft 621. A transverse plate 623 is installed at the rear end of the motor 622. The transverse plate 623 is fixedly installed on the right side of the outer housing 2.

[0085] Among them, the rectangular outer shell 41 and the side protective plate 411 are both made of sound insulation material;

[0086] Among them, the emergency stop button 6 is a manual control button, used to stop the power supply to the entire test bench when the current inside the high-integration standard burner test bench exceeds the safe current but does not reach the critical current of the air switch, so as to ensure the safety of the entire test bench; the switch button 7 is used to connect the main power supply of the equipment casing; the indicator light 8 is used to display the opening and closing of the entire test bench.

[0087] By setting up an alarm 42 and a controller 43, and based on the distance of the relay, the alarm 42 and the motor 622 are linked for control. When the current in the high-integration standard burner test bench exceeds the safe current but does not reach the critical current of the air switch, the alarm 42 sounds an alarm. The controller 43 controls the motor 622 to start, which drives the eccentric wheel 62 to rotate, thereby pressing the emergency stop button 6 on the left end of the protective disc 61. This achieves automatic opening and closing of the emergency stop button 6, thereby automatically stopping the power supply. The circuit principle is a known conventional distance. Through this setting, the entire test bench is protected twice, making it safer and more reliable.

[0088] The present invention employs flow control, temperature detection, gas filtration (including gas drying and gas filtration) and shell assembly to form the overall structure of the highly integrated standard burner test bench. It adopts a visual approach, mainly by setting various control buttons, indicator lights and various dials (such as temperature display 22, flow display 27, etc.) on the surface of the outer shell 2.

[0089] The present invention uses K-type thermocouples to connect each main gas pipeline, that is, the gas pipeline directly connected to the flow meter 31, such as the first connecting pipeline 32, to measure the gas temperature in the main pipeline and compare it with the temperature set by the temperature control instrument to form a loop feedback system to adjust the heating or temperature stabilization state. During the entire operation, the current magnitude is monitored by the ammeter on the main panel.

[0090] In summary, this invention employs a combination of flow control, temperature detection, and gas filtration. In practical applications, the gas flow rate and its boundary conditions can be controlled through electrical control.

[0091] This invention, through the setup of this highly integrated standard burner test bench, combines the standard burner with an optimized temperature control system and flow control system to construct an integrated and compact standard burner. This will provide important theoretical support for obtaining more accurate basic combustion data and will have a positive impact on the development and optimization of subsequent combustion models. Furthermore, by incorporating a spare pipeline assembly 33 and a pipeline cleaning and anti-corrosion assembly 34, this invention can effectively protect the flow meter 31, slowing down the corrosion rate inside the flow meter 31, thereby extending the service life of the flow meter 31 while ensuring its accuracy.
