Description

Technical Field

[0001] The utility model belongs to the technical field of solid waste recycling and treatment, and in particular relates to ground torch equipment. Background Art

[0002] Pyrolysis of scrap tires is an irreversible thermochemical reaction that uses high temperatures in an oxygen-free or oxygen-deficient atmosphere to decompose organic matter in scrap tires, releasing volatile products and forming solid coke. This incomplete thermal degradation process can produce gaseous, liquid, and solid products. This method can completely pyrolyze scrap tires into useful products such as pyrolysis oil, pyrolysis carbon black, and pyrolysis non-condensable gases.

[0003] Flare systems are specialized combustion facilities used to treat flammable and toxic gases and vapors that cannot be recovered or reprocessed in petrochemical plants, pyrolysis plants, chemical plants, and other plants or facilities. They are a crucial measure to ensure safe production and reduce environmental pollution. Ground flare systems ensure that gases are vented and burned promptly, safely, and reliably when they need to be discharged or when pyrolysis equipment experiences abnormal conditions.

[0004] However, due to oxidation and cracking reactions during combustion of hydrocarbons in the flare, when the temperature is above 400°C and there is a lack of oxygen, traditional flares will produce black smoke that is difficult to burn completely. Utility Model Content

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is described and illustrated below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] The embodiment of the utility model provides a ground flare device, Figure 1This is a structural diagram of the ground flare equipment according to an embodiment of the present invention. Figure 1 As shown, the ground flare equipment includes several burners 1, air distribution pipes 2, exhaust gas pipes 3, water seal tanks 4, and heat shields 5. The burners 1 are used to burn the discharged combustible gas. The air outlet of the air distribution pipe 2 is connected to the burners 1 and supplies oxygen to the burners 1. The air outlet of the exhaust gas pipe 3 is connected to the burners 1 and conveys the discharged combustible gas to the burners 1. The water seal tank 4 is connected to the air inlet of the exhaust gas pipe 3. The heat shield 5 encloses a storage space for accommodating the burners 1. In some embodiments, the number of burners 1 is at least three.

[0028] The above-mentioned ground flare equipment supplies oxygen to the combustion process of the combustible gas by setting up an air distribution duct 2, thereby ensuring the complete combustion of the combustible gas. By setting up a water seal tank 4 and limiting the setting of the water seal tank 4 to be external, the safety hazard caused by the occurrence of backfire is prevented, thereby ensuring the safety of the complete combustion process of the combustible gas. By setting up a heat insulation cover 5, the gas venting and combustion flame can be completely controlled within the radiation-proof heat insulation cover 5, thereby minimizing the impact of heat radiation and noise on workers and surrounding equipment. The ground flare equipment can be well applied to situations where the flare discharge volume is large in the event of an accident or production anomaly, and the hydrocarbons cannot be completely burned by oxygen in the air alone. By forcing oxygen to the torch and designing the flare burner 1 composite combustion head 104, low-noise and smokeless combustion can be achieved during operation.

[0029] like Figure 2 、 3 As shown in Figures 4 and 5, in order to ensure stable and efficient combustion, each burner 1 includes a straight pipe 101, an annular pipe 102, a plurality of connecting pipes 103, and a plurality of combustion heads 104; the straight pipe 101 is connected to the exhaust gas duct 3; the annular pipe 102 is connected to the air distribution duct 2, and the annular pipe 102 is arranged around the straight pipe 101 and is perpendicular to the straight pipe 101, and the straight pipe 101 is located at the center of the annular pipe 102; the connecting pipes 103 are evenly arranged along the circumference of the straight pipe 101 and are located above the annular pipe 102; the air outlet of each connecting pipe 103 is arranged vertically upward, one air inlet is connected to the air outlet opened on the circumferential side of the straight pipe 101, and the other air inlet is connected to the air outlet opened on the radial side of the straight pipe 101; each combustion head 104 is connected to the air outlet of the connecting pipe 103. In some embodiments, the circumferential side of the straight tube 101 is evenly provided with a corresponding number of air outlets correspondingly connected to an air inlet of the plurality of connecting tubes 103; the radial side of the annular tube 102 is evenly provided with a corresponding number of air outlets correspondingly connected to another air inlet of the plurality of connecting tubes 103.

[0030] Furthermore, each burner 1 also includes an ignition element 105 for igniting the combustion head 104 after combustible gas is introduced into the exhaust gas pipeline 3. To achieve automated and accurate control, the ignition element 105 is a pulse ignition device, which also includes a combustible gas detection sensor connected to the exhaust gas pipeline 3, and a PLC sensor electrically connected to the combustible gas detection sensor, and the PLC sensor is electrically connected to the pulse ignition device. Specifically, the torch exhaust gas pipeline 3 is provided with a torch automatic pulse ignition device. When the torch automatic pulse ignition device senses the passage of gas, it activates the ignition system, igniting the three sets of torch burner 1 composite combustion heads 104 for combustion.

[0031] Furthermore, in order to improve the complete combustion of hydrocarbons in the exhaust gas, the air inlet of the air distribution pipe 2 is connected to an oxygen-enhancing air distribution high-pressure blower 6, and the air distribution pipe 2 is provided with an oxygen control valve to force oxygen supply to the torch.

[0032] Regarding the above ground flare equipment, specifically:

[0033] The composite combustion head 104 assembly of the flare burner 1 is composed of three groups of components with identical structures. Its specific structure is:

[0034] The flare exhaust gas main pipeline is connected to the main pipeline outlet of burner 1, and is connected to the annular flare burner 1 exhaust gas inlet secondary pipeline. On the annular flare burner 1 exhaust gas inlet secondary pipeline, three flare burner 1 flare exhaust gas inlet manifolds are equidistantly arranged. In order to improve the complete combustion of hydrocarbons in the exhaust gas, it is necessary to force oxygen supply to the flare. Therefore, an oxygen-enriched air distribution high-pressure blower 6 is installed in the ground flare system. The air outlet of the oxygen-enriched air distribution high-pressure blower 6 is connected to the oxygen-enriched air distribution duct 2. The air distribution duct 2 is provided with an oxygen control valve. The right side of the combustion oxygen-enriched air distribution blower delivery pipeline is connected to the annular flare burner 1 air distribution secondary pipeline.

[0035] The air distribution duct 2 is connected to the annular flare burner 1 air distribution inlet secondary duct. Three flare burner 1 flare distribution duct inlet manifolds are evenly spaced on the annular flare burner 1 air distribution inlet secondary duct. The entire ground flare combustion system is equipped with three groups of flare composite burner 1 assemblies. Each group of flare composite burner 1 assemblies has a flare burner 1 air distribution inlet, which is used to increase oxygen for sufficient combustion. The flare burner 1 air distribution inlet main duct is connected to the external oxygen supply air distribution fan delivery duct. Three equidistant air supply manifolds are also installed on the flare burner 1 air distribution inlet main duct. The flare burner 1 flare exhaust gas inlet main duct is connected to the flare exhaust gas main duct and the burner 1 connection main duct. Three flare burner 1 flare exhaust gas inlet manifolds are evenly spaced along the circumference of the flare burner 1 flare exhaust gas inlet main duct. The flare burner 1 has a composite combustion head 104. The flare burner 1 exhaust pipe is located at the outermost edge of the composite combustion head 104. The flare burner 1 exhaust pipe is fitted with a flare burner 1 air distribution pipe. A flare burner 1 cyclone deflector is located between the flare burner 1 exhaust pipe and the flare burner 1 air distribution pipe. The lower portion of the ground flare is also equipped with a foundation, a safety protection wall, and a radiation-proof heat shield 5.

[0036] like Figure 5 As shown, the number of water seal tanks 4 is at least 2, and multiple water seal tanks 4 are connected in series. Each water seal tank 4 is provided with a water supply port and an overflow port, and a control valve is provided in front of the water supply port and the overflow port. The combustible gas discharged from the thermal cracking unit first enters the flare exhaust gas inlet main pipeline. In order to prevent the flare from backfireing during combustion, the combustible gas transported from the flare exhaust gas inlet main pipeline first enters the 1# water seal tank 4. The water seal tank 4 is a vertical design, and the air inlet is set on the left side of the upper head. The air inlet main pipeline is connected to the water seal pipe flange interface in the 1# water seal tank 4, and the water seal pipe in the tank extends about 500mm into the lower edge of the upper head. A water supply port is vertically provided on the upper left side of the cylinder body of 1# water seal tank 4, and a flow control valve is provided in front of the water supply port. An overflow port is vertically provided on the middle upper right side of the cylinder body of 1# water seal tank 4, and a control valve is provided in front of the overflow port. When the water level in the cylinder body reaches the center line of the overflow port, the water supply port can be interlocked to stop water supply, and the water supply port and the overflow port valve can be closed at the same time. A liquid level gauge is provided on the front of the cylinder body of 1# water seal tank 4 to observe the water level height in the water seal tank 4, so as to facilitate timely water supply or sewage discharge. The flare gas outlet of 1# water seal tank 4 is vertically provided on the right side of the upper head, and is connected to the connecting pipes in the middle of 1# water seal tank 4 and 2# water seal tank 4. A pressure gauge is provided on the upper head of 1# water seal tank 4, and a sewage outlet is also provided on the lower head of 1# water seal tank 4.

[0037] For safety reasons, the ground flare system utilizes a multi-stage water seal configuration. In addition to the 1# water seal tank 4, a 2# water seal tank 4 is also installed. Water seal tank 4 is also vertically designed, with the air inlet of 2# water seal tank 4 located on the left side of the upper head. The air inlet of 2# water seal tank 4 is connected to the middle pipe flange of 1# water seal tank 4 and 2# water seal tank 4. The water seal pipe in the tank extends approximately 500mm into the lower edge of the upper head. A water inlet is vertically located on the upper left side of the 2# water seal tank 4 cylinder, with a flow control valve installed in front of the inlet. An overflow outlet is vertically located in the upper right side of the 2# water seal tank 4 cylinder, with a control valve installed in front of the overflow outlet. When the water level in the cylinder reaches the centerline of the overflow outlet, the water inlet is interlocked and the overflow valve is closed. A liquid level gauge is installed on the front of the 2# water seal tank 4 cylinder to monitor the water level in water seal tank 4, facilitating timely water supply or sewage discharge. The 2# water seal tank 4 flare gas outlet is vertically arranged on the right side of the upper head and is connected to the inlet pipe of the flare exhaust gas pipeline 3. Setting up a multi-stage water seal system can keep the flare system in a relatively safe state at all times. The function of the water seal tank 4 is to prevent the occurrence of backfire. Assuming that backfire occurs, after the flame enters the water seal tank 4 through the flare gas outlet, the inlet pipe is below the water surface, thus preventing the flame from continuing to spread. The 2# water seal tank 4 flare gas outlet is connected to the inlet of the flare exhaust gas pipeline 3. A flow control valve is provided on the left side of the middle of the flare exhaust gas pipeline 3 to control the flow of the input gas. The right side of the flow control valve is connected to the air inlet of the main pipeline connecting the flare exhaust gas pipeline 3 and the burner 1, and the air outlet is connected to the air inlet of the flare burner 1 assembly.

[0038] The working process of the above-mentioned ground flare equipment is as follows:

[0039] The combustible gas passes through the water seal tank 4 and is then transported to the burner 1 through the exhaust gas pipe 3. At the same time, the air distribution pipe 2 supplies oxygen to the burner 1. The combustible gas is completely burned in the burner 1, and this combustion process occurs in the heat insulation cover 5, minimizing the impact of heat radiation and noise on workers and surrounding equipment.

[0040] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
