Description

Technical Field

[0001] The invention relates to the field of waste liquid treatment, in particular to a multi-fuel combustion system. Background Art

[0002] Waste liquid includes leachate, leaching liquid, sludge dehydration, fermentation sludge, etc. from urban landfills, waste incineration plants, and waste composting plants. Long-term exposure to waste liquid is extremely harmful, leading to long-term poisoning, carcinogenicity, teratogenicity, and mutagenicity. The common method of treating waste liquid is combustion, but due to the large variety of waste liquids, different waste liquids cannot be mixed, so it is more common to configure one waste liquid spray gun for one waste liquid spray gun. The traditional method is to design one waste liquid spray gun for one burner. If there are multiple waste liquids on site, multiple waste liquid burners need to be configured, but the on-site environment does not allow the installation of too many burners. Summary of the invention

[0003] Based on this, it is necessary to design a waste liquid spray gun for a burner and provide a multi-fuel combustion system.

[0004] A multi-fuel combustion system, the multi-fuel combustion system comprising: a combustion-supporting air system, the combustion-supporting air system is provided with a combustion-supporting air inlet and a combustion-supporting air outlet, the combustion-supporting air inlet and the combustion-supporting air outlet are connected; a fuel system, the fuel system is used to be connected with external fuel; a waste liquid system, the waste liquid system is used to be connected with external waste liquid; an air blowing system, the air blowing system is provided with an air inlet, the air blowing system is respectively connected with the fuel system and the waste liquid system; a combustion device, the combustion device is provided with a combustion air inlet, the combustion-supporting air outlet provided in the combustion-supporting air system is connected with the combustion air inlet, and the fuel system, the waste liquid system and the air blowing system are connected with the combustion device.

[0005] The present application discloses a multi-fuel combustion system, wherein a combustion-supporting air inlet and a combustion-supporting air outlet are arranged in a combustion-supporting air system, a combustion air inlet is arranged in a combustion device, the combustion air outlet and the combustion air inlet are connected, the combustion-supporting air enters the combustion-supporting air system from the combustion-supporting air inlet, and is transported to the combustion air inlet through the combustion-supporting air outlet, thereby providing sufficient oxygen for the combustion device, and sufficient oxygen enables the fuel to be fully burned in the combustion device, thereby improving the combustion efficiency, and reducing the pollutants and energy waste generated by incomplete combustion. The fuel system, the waste liquid system and the blowing system are arranged on the combustion system, and the blowing system is connected to the fuel system and the waste liquid system, and air enters from the air inlet to effectively atomize the fuel and the waste liquid, and the atomized fuel and the waste liquid form extremely small particles, which increases the contact area with the combustion-supporting air, making the combustion more complete and rapid, significantly improving the combustion efficiency, and reducing energy waste. At the same time, the atomized fuel and waste liquid burn more completely, reducing the generation of incomplete combustion products, and helping to reduce the emission of pollutants and protect the environment. The multiple waste liquid spray guns of the multi-fuel combustion system can effectively treat a variety of different types of industrial waste liquids, avoiding serious environmental pollution caused by direct discharge of waste liquids. Through combustion treatment, harmful substances in the waste liquid are converted into relatively harmless substances, such as carbon dioxide, water and some solid residues, reducing damage to the ecological environment.

[0006] In one embodiment, the combustion-supporting air system includes a suction component, a control component and a combustion-supporting air duct, the suction component and the control component are both arranged on the combustion-supporting air duct, the suction component is provided with a combustion-supporting air inlet, the combustion-supporting air duct is arranged on the combustion device, the combustion-supporting air duct is provided with a combustion-supporting air outlet, and the control component is used to control the flow of the combustion-supporting air. By arranging the suction component and the control component on the combustion-supporting air duct, the suction component sucks the combustion-supporting air into the combustion-supporting air system from the combustion-supporting air inlet, so that the combustion-supporting air smoothly passes into the combustion-supporting air duct. By utilizing the control component, the combustion-supporting air flow in the combustion-supporting air duct can be monitored in real time and the flow of the combustion-supporting air can be precisely controlled, so that the ratio of the combustion-supporting air to the fuel reaches the optimal state and efficient combustion is achieved. A suitable combustion-supporting air flow can maintain a stable combustion flame, which is crucial to the safe operation of the combustion system and the product quality. If the combustion-supporting air flow is unstable, the flame may flicker, shake or go out, affecting the stability of the combustion process and may even cause a safety accident. At the same time, different waste liquids require different combustion-supporting air flow rates. The control components can flexibly adjust the combustion-supporting air flow rate according to actual needs to adapt to various combustion conditions, so that the waste liquid can be fully burned and the purpose of protecting the ecological environment can be achieved.

[0007] In one embodiment, the suction assembly includes a suction grid, a silencer and a combustion-supporting fan, and the suction grid, the silencer and the combustion-supporting fan are all arranged on the combustion-supporting air duct, and the combustion-supporting air passes through the suction grid, the silencer and the combustion-supporting fan in sequence. By arranging the suction grid, the silencer and the combustion-supporting fan on the combustion-supporting air duct, and the combustion-supporting air passes through the suction grid, the silencer and the combustion-supporting fan in sequence, when the combustion-supporting air enters the suction grid, the suction grid can block impurities such as dust and particulate matter in the air from entering the combustion-supporting air duct, which helps to keep the combustion-supporting air clean and prevent impurities from having an adverse effect on the combustion process. For example, impurities may clog the burner nozzle, affect combustion efficiency or damage combustion equipment. At the same time, the suction grid can adjust the airflow entering the combustion-supporting air duct to a certain extent. It can change the direction and velocity distribution of the airflow, so that the combustion-supporting air enters the combustion system more evenly. Since the combustion-supporting fan will generate a lot of noise during operation, the silencer can effectively reduce the noise level of the combustion-supporting air system, effectively improve the working environment, reduce noise pollution, and avoid interference with the surrounding environment and personnel. The combustion-supporting fan is the core component of the combustion-supporting air system. It provides power for the flow of combustion-supporting air. By generating a certain wind pressure and air volume, the combustion-supporting fan delivers air into the combustion system to ensure that the fuel can be fully burned.

[0008] In one embodiment, the fuel system includes a filter, a fuel control assembly, a first fuel pipeline and a fuel atomization pipeline, wherein the filter and the fuel atomization pipeline are arranged on the first fuel pipeline, the number of the fuel control assemblies is multiple, and the multiple fuel control assemblies are respectively arranged on the first fuel pipeline and the fuel atomization pipeline, the fuel atomization pipeline is communicated with the first fuel pipeline, the first fuel pipeline is arranged on the combustion device, and the fuel atomization pipeline is connected to the blowing system. By arranging the filter on the first fuel pipeline, impurities such as solid particles, rust, and dust in the fuel can be effectively removed. If these impurities enter the combustion system, they may clog the fuel nozzle, affect the combustion efficiency, damage the combustion equipment, and even cause safety accidents. The purity of the fuel can be guaranteed by filtering, and the reliability and stability of the combustion system can be improved. The fuel atomization pipeline is led out from the first fuel pipeline, and the fuel atomization pipeline is connected to the blowing system. When atomized fuel is required, the fuel control assembly arranged on the first fuel pipeline and the fuel atomization pipeline is controlled to input fuel and air to the first fuel pipeline and the blowing system respectively, thereby improving the efficiency and effect of atomization. When the combustion is finished, the fuel control assembly is controlled to allow the air of the blowing system to enter the first fuel pipeline from the fuel atomization pipeline, so as to clean the first fuel pipeline and keep the fuel system clean.

[0009] In one embodiment, the fuel control assembly includes a pressure control assembly, a pneumatic valve and a check valve, wherein the pressure control assembly is arranged on the first fuel pipeline, the pneumatic valve is arranged on the first fuel pipeline and the fuel atomization pipeline, and the check valve is arranged on the fuel atomization pipeline. By arranging the pressure control assembly on the first fuel pipeline, a stable fuel supply pressure is ensured. If the pressure fluctuation is too large, the combustion of the burner will be unstable, the size and shape of the flame will change unpredictably, and the combustion efficiency and heat output will be affected. The pressure control assembly can monitor and adjust the pressure in the fuel pipeline in real time to ensure that the pressure is always kept within a suitable range, thereby ensuring the stability of combustion. The pneumatic valve is arranged on the first fuel pipeline and the fuel atomization pipeline, and the pneumatic valve can accurately adjust the flow rate of the fuel according to the instructions of the control system. By adjusting the opening of the valve, the fine control of the fuel supply amount can be achieved to meet the needs under different combustion conditions, and the purpose of efficient combustion, optimizing energy utilization and controlling the combustion process is achieved. The check valve is arranged on the fuel atomization pipeline, which can effectively prevent the fuel from flowing back from the first fuel pipeline to the fuel atomization pipeline, interfering with the conveying process of the atomization air, and can also ensure that the atomization air maintains a stable pressure in the pipeline.

By dividing the waste liquid system into a high-temperature waste liquid system and a medium-temperature waste liquid system, since the waste liquid temperatures and characteristics generated in different industries and production processes are different, waste liquids with different temperatures and different characteristics have different physical and chemical properties, and have different requirements for combustion. After the waste liquid system is separated, the high-temperature waste liquid and the medium-temperature waste liquid can be burned separately according to their characteristics, the combustion conditions can be optimized, and the combustion efficiency can be improved. At the same time, separate treatment can avoid heating all waste liquids to high temperatures for combustion, thereby reducing energy waste. For medium-temperature waste liquid, a relatively low temperature can be used for treatment to save energy costs. The high-temperature waste liquid system and the medium-temperature waste liquid system are connected to the blowing system, and the ends of the two systems are connected to the combustion device. The blowing system can be used to atomize the waste liquid in the high-temperature waste liquid system and the medium-temperature waste liquid system to improve the efficiency of waste liquid combustion, so that the waste liquid entering the combustion device can be completely burned.

[0011] In one embodiment, the high-temperature waste liquid system includes a first filter, a first control component, a first high-temperature pipeline and a high-temperature atomization pipeline. The first filter is arranged on the first high-temperature pipeline. The number of the first control components is multiple. The multiple first control components are arranged on the first high-temperature pipeline and the high-temperature atomization pipeline respectively. The high-temperature atomization pipeline is arranged on the first high-temperature pipeline. The first high-temperature pipeline is connected to the combustion device, and the high-temperature atomization pipeline is connected to the blowing system. By arranging the first filter in the first high-temperature pipeline, various solid particles, sediments, fibers and other impurities in the waste liquid are removed to avoid blockage caused by impurities, and the risk of accidents in the system is reduced. The high-temperature atomization pipeline is extended from the first high-temperature pipeline and connected to the blowing system. When the waste liquid needs to be atomized, the first control component arranged in the first high-temperature pipeline and the high-temperature atomization pipeline is controlled to input waste liquid and air into the first high-temperature pipeline and the blowing system respectively, so as to improve the efficiency and effect of atomization. When the combustion is finished, the first control component is controlled again to allow the air of the blowing system to enter the first high-temperature pipeline from the high-temperature atomization pipeline, clean the first high-temperature pipeline, and keep the combustion system clean.

By arranging the second filter in the first medium temperature pipe, various solid particles, sediments, fibers and other impurities in the waste liquid are removed to avoid blockage caused by impurities, and the risk of accidents in the system is reduced. The medium temperature atomization pipe is extended from the first medium temperature pipe and connected to the blowing system. When the waste liquid needs to be atomized, the second control component arranged in the first medium temperature pipe and the medium temperature atomization pipe is controlled to input waste liquid and air into the first medium temperature pipe and the blowing system respectively, so as to improve the efficiency and effect of atomization. When the combustion is finished, the second control component is controlled again to allow the air of the blowing system to enter the first medium temperature pipe from the medium temperature atomization pipe, clean the first medium temperature pipe, and keep the combustion system clean.

[0013] In one embodiment, the blowing system includes a water-gas separator and a blowing pipe, the water-gas separator is arranged on the blowing pipe, the blowing pipe is provided with the air inlet, the number of the blowing pipes is multiple, and the multiple blowing pipes are connected to the fuel system and the waste system. By arranging the water-gas separator on the blowing pipe, since the air usually contains a certain amount of moisture, when the air is compressed or under a specific environment, the moisture may condense into water droplets. If these moisture enters the blowing system from the air inlet, it will affect the effect and stability of the blowing, and affect the subsequent atomization function. The water-gas separator can effectively remove moisture from the air to ensure that the wind blown into the combustion system or other equipment is dry. At the same time, it can also prevent equipment corrosion, reduce the risk of corrosion to the equipment, and protect the normal operation of the equipment. Of course, moisture entering the equipment may cause electrical failures, mechanical failures and other problems. The water-gas separator can remove moisture, reduce the risk of equipment failure, and improve the reliability and stability of the equipment. Arranging multiple blowing pipes can simultaneously atomize the fuel provided by the fuel system and the waste liquid provided by the waste system, so as to achieve an efficient combustion process.

By connecting the fuel system and the blowing system with the fuel spray gun, connecting the high-temperature waste liquid system and the medium-temperature waste liquid system and the blowing system of the waste liquid system with the first waste liquid spray gun and the second waste liquid spray gun, and at the same time setting the combustion-supporting air system at the combustion air inlet of the burner body, atomized fuel and waste liquid are input into the corresponding spray guns, and the combustion-supporting air provided by the combustion-supporting air system is used to provide sufficient oxygen for combustion. After starting the ignition device, the waste liquid can be completely burned in the burner body, thereby improving combustion efficiency, reducing energy waste, reducing the emission of incomplete combustion products, and avoiding incomplete combustion of waste liquid.

[0015] In one embodiment, the ignition device includes an ignition gun and an ignition controller, wherein the ignition gun is arranged on the burner body, and the ignition controller is arranged on the ignition gun. By arranging the ignition gun on the burner body and the ignition controller on the ignition gun, the accuracy of the ignition position can be ensured, and the ignition controller is used to make the ignition source act directly on the mixed area of ​​the fuel and the combustion-supporting air, thereby improving the ignition success rate. The precise ignition position helps to quickly ignite the fuel and reduce the ignition time and energy waste. Moreover, according to different fuel types, combustion conditions and operating requirements, the ignition parameters can be accurately adjusted to achieve the best ignition effect, improve the reliability and stability of ignition, and reduce the risk of ignition failure.

[0033] The present application discloses a multi-fuel combustion system, wherein a combustion-supporting air inlet 101 and a combustion-supporting air outlet 102 are provided in a combustion-supporting air system 1, a combustion air inlet 501 is provided in a combustion device 5, the combustion-supporting air outlet 102 and the combustion air inlet 501 are connected, the combustion-supporting air enters the combustion-supporting air system 1 from the combustion-supporting air inlet 101, and is transported to the combustion air inlet 501 through the combustion-supporting air outlet 102, thereby providing sufficient oxygen for the combustion device 5. The sufficient oxygen can enable the fuel to be fully burned in the combustion device 5, thereby improving the combustion efficiency and reducing pollutants and energy waste caused by incomplete combustion. The fuel system 2, the waste liquid system 3 and the blowing system 4 are arranged on the combustion system 5, and the blowing system 4 is connected to the fuel system 2 and the waste liquid system 3. The air enters from the air inlet 401 to effectively atomize the fuel and the waste liquid. The atomized fuel and waste liquid form extremely small particles, which increases the contact area with the combustion-supporting wind, making the combustion more complete and rapid, significantly improving the combustion efficiency, and reducing energy waste. At the same time, the atomized fuel and waste liquid burn more completely, reducing the generation of incomplete combustion products, helping to reduce pollutant emissions and protect the environment. The multiple waste liquid spray guns of the multi-fuel combustion system can effectively treat a variety of different types of industrial waste liquids, avoid the serious pollution to the environment caused by direct discharge of waste liquids, and convert harmful substances in the waste liquids into relatively harmless substances, such as carbon dioxide, water and some solid residues through combustion treatment, reducing damage to the ecological environment.

[0034] like Figure 1 and Figure 2 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the combustion-supporting air system 1 includes a suction component 11, a control component 12 and a combustion-supporting air duct 13, the suction component 11 and the control component 12 are both arranged on the combustion-supporting air duct 13, the suction component 11 is provided with a combustion-supporting air inlet 101, the combustion-supporting air duct 13 is arranged on the combustion device 5, the combustion-supporting air duct 13 is provided with a combustion-supporting air outlet 102, and the control component 12 is used to control the flow rate of the combustion-supporting air. By arranging the suction component 11 and the control component 12 on the combustion-supporting air duct 13, the suction component 11 sucks the combustion-supporting air into the combustion-supporting air system 1 from the combustion-supporting air inlet 101, so that the combustion-supporting air can smoothly pass through the combustion-supporting air duct 13, and by using the control component 12, the combustion-supporting air flow rate in the combustion-supporting air duct can be monitored in real time and the flow rate of the combustion-supporting air can be accurately controlled, so that the ratio of the combustion-supporting air to the fuel reaches the optimal state, and efficient combustion is achieved. Appropriate combustion-supporting air flow can maintain a stable combustion flame. A stable flame is essential for the safe operation of the combustion system and product quality. If the combustion-supporting air flow is unstable, the flame may flicker, shake or go out, affecting the stability of the combustion process and may even cause a safety accident. At the same time, different waste liquids require different combustion-supporting air flows. The control component can flexibly adjust the combustion-supporting air flow according to actual needs to adapt to various combustion conditions, so that the waste liquid can be fully burned and the purpose of protecting the ecological environment can be achieved.

[0035] like Figure 1 and Figure 2 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the suction assembly 11 includes a suction grid 111, a muffler 112 and a combustion-supporting fan 113, and the suction grid 111, the muffler 112 and the combustion-supporting fan 113 are all arranged on the combustion-supporting air duct 13, and the combustion-supporting air passes through the suction grid 111, the muffler 112 and the combustion-supporting fan 113 in sequence. By arranging the suction grid 111, the muffler 112 and the combustion-supporting fan 113 on the combustion-supporting air duct 13, and the combustion-supporting air passes through the suction grid 111, the muffler 112 and the combustion-supporting fan 113 in sequence, when the combustion-supporting air enters the suction grid 111, the suction grid 111 can block impurities such as dust and particulate matter in the air from entering the combustion-supporting air duct 13, which helps to keep the combustion-supporting air clean and prevent impurities from having an adverse effect on the combustion process. For example, impurities may clog the burner nozzle, affect the combustion efficiency or damage the combustion equipment. At the same time, the suction grille 111 can adjust the airflow entering the combustion-supporting air duct 13 to a certain extent. It can change the direction and speed distribution of the airflow, so that the combustion-supporting air enters the combustion system more evenly. Since the combustion-supporting fan 113 will generate a lot of noise during operation, the muffler 112 can effectively reduce the noise level of the combustion-supporting air system, effectively improve the working environment, reduce noise pollution, and avoid interference with the surrounding environment and personnel. The combustion-supporting fan 113 is the core component of the combustion-supporting air system. It provides power for the flow of the combustion-supporting air. By generating a certain wind pressure and air volume, the combustion-supporting fan 113 delivers air into the combustion system to ensure that the fuel can be fully burned.

By arranging the filter 21 on the first fuel pipeline 23, impurities such as solid particles, rust, and dust in the fuel can be effectively removed. If these impurities enter the combustion system, they may block the fuel nozzle, affect the combustion efficiency, damage the combustion equipment, and even cause a safety accident. The purity of the fuel can be guaranteed by filtering, and the reliability and stability of the combustion system can be improved. The fuel atomization pipeline 24 is led out from the first fuel pipeline 23, and the fuel atomization pipeline 24 is connected to the blowing system 4.

By dividing the waste liquid system 3 into the high-temperature waste liquid system 31 and the medium-temperature waste liquid system 32, since the waste liquid temperatures and characteristics generated in different industries and production processes are different, waste liquids with different temperatures and different characteristics have different physical and chemical properties, and have different requirements for combustion. After the waste liquid system is separated, the high-temperature waste liquid and the medium-temperature waste liquid can be burned separately according to their characteristics, the combustion conditions can be optimized, and the combustion efficiency can be improved. At the same time, separate treatment can avoid heating all waste liquids to high temperatures for combustion, thereby reducing energy waste. For medium-temperature waste liquid, a relatively low temperature can be used for treatment to save energy costs. The high-temperature waste liquid system 31 and the medium-temperature waste liquid system 32 are connected to the blowing system 4, and the ends of the two systems are connected to the combustion device 5.
