Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-temperature incinerators, in particular to a high-temperature incinerator instrument protection windage prevention system. Background Art
[0002] With the acceleration of industrialization, environmental pollution is becoming increasingly serious. Oil and gas odor pollution and the recovery of toxic hydrogen sulfide gas are major environmental issues that have attracted widespread public attention. Oil and gas odor primarily originates from volatile organic compounds such as mercaptans, hydrogen sulfide, and methane released during petroleum refining, storage, and transportation. These odors not only degrade the surrounding environment and affect residents' quality of life, but also pose a threat to human health. For example, hydrogen sulfide is a toxic gas; long-term exposure can cause damage to the nervous system and lead to symptoms such as dizziness and fatigue. Methane, on the other hand, carries a certain explosion hazard, posing a serious threat to production safety.
[0003] At present, incineration is mostly used to control oil and gas odors and recover hydrogen sulfide. The temperature of the incinerator is generally above 800°C. It is an important measure to ensure that factory emissions are qualified and reduce environmental pollution. It is an indispensable process in petrochemical plants, refineries, etc.
[0004] Currently, high-temperature incinerators such as RTO furnaces (for oil and gas incineration) and hydrogen sulfide gas incinerators (for hydrogen sulfide recovery) are used in sewage treatment plants, maleic anhydride plants, and sulfur recovery plants. RTO furnaces for oil and gas incineration operate at temperatures around 800-1000°C, while hydrogen sulfide gas incinerators operate at around 1250°C. To monitor the safe operation of high-temperature incinerators, multiple temperature detection points, flame detection points, and flame observation holes are installed on the furnace body. When the furnace temperature is high, shorting these points, flame detection points, and flame observation holes poses a risk of overheating and damage. Therefore, protective airflow is typically installed at these points to reduce the temperature. However, during actual operation, interruptions in the protective airflow can occur, leading to toxic gas leaks and fires, posing significant risks to the operation and environmental protection of the plant. Therefore, a solution is urgently needed to prevent interruptions in the protective airflow of high-temperature incinerators to address this issue. Utility Model Content

[0006] The technical solution of the utility model is:

The utility model also achieves the purpose of evenly distributing the flow of each protective air branch line by setting a flow limiting orifice on each protective air branch line, preventing the occurrence of biased flow that causes the flow of a certain protective air line to be too small, resulting in the failure of the protective air.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.
[0021] Example 1
[0022] like Figure 1 As shown, this embodiment provides a high-temperature incinerator instrument protection wind interruption prevention system, and the high-temperature incinerator 1 is provided with a fire viewing hole 101, an infrared temperature detection port 102, a flame detection port 103, a fuel gas inlet 104, an ignition device installation port 105, a thermocouple temperature detection port 106 and a middle feed port 107. The fire viewing hole 101, the infrared temperature detection port 102, the flame detection port 103, the fuel gas inlet 104, the ignition device installation port 105, the thermocouple temperature detection port 106 and the middle feed port 107 are respectively provided with valves 8, and then the corresponding components such as infrared temperature sensors, flame detectors, thermocouples, etc. are installed by short-circuiting.
[0023] In order to cool down the short circuit connected to the above components to prevent them from being damaged by overheating, Figure 1 As shown, the fire viewing hole 101, the infrared temperature detection port 102, the flame detection port 103, the fuel gas inlet 104, the ignition equipment installation port 105, the thermocouple temperature detection port 106 and the middle feed port 107 are respectively connected to the protective air branch pipeline 2, and each protective air branch pipeline 2 is connected to the protective air main pipeline 3, and protective air is blown into it to cool it down. The blown protective air enters the high-temperature incinerator 1 to play a combustion-supporting role.
[0024] At the same time, if Figure 1As shown, in this embodiment, a flow meter 4 and a pressure gauge 5 are installed on the main protective air pipeline 3. The flow meter 4 is electrically connected to the control system. By on-site observation and detection of the pressure of the main protective air pipeline 3 and real-time monitoring of its flow rate, it is possible to monitor whether the protective air supply is interrupted. If an abnormal drop in pressure and flow rate is detected, it indicates that there is a problem with the main protective air pipeline 3 and it needs to be investigated. If the pressure rises abnormally and the flow rate decreases, it indicates that a fault has occurred in a branch protective air pipeline 2 and each branch protective air pipeline 2 needs to be investigated individually.
[0025] In addition, if Figure 1 As shown, valves 8 are provided at both ends of the flowmeter 4 on the protective air main pipeline 3. The protective air main pipeline 3 is connected to the protective air auxiliary pipeline 3 12, which is also provided with a valve 8. When the flowmeter 4 needs to be repaired or replaced, the valves 8 at both ends of the flowmeter 4 can be closed and the valve 8 on the protective air auxiliary pipeline 3 12 can be opened. The flowmeter 4 can then be disconnected from the protective air main pipeline 3. This allows the flowmeter 4 to be repaired or replaced while ensuring the normal supply of protective air.
[0026] Example 2
[0027] On the basis of Example 1, Figure 1 As shown, a pressure sensor 6 is provided on the main protection air pipeline 3, and the pressure sensor 6 is electrically connected to the control system. The pressure sensor 6 can be used to remotely monitor the pressure of the main protection air pipeline 3 in real time, enabling more timely and automatic monitoring of the pressure of the main protection air pipeline 3, and more efficient monitoring.
[0028] Example 3
[0029] On the basis of Example 1, Figure 1 As shown, a flow-limiting orifice plate 7 is provided on the protective air branch line 2. The flow-limiting orifice plate 7 can evenly distribute the flow of each protective air branch line 2, preventing biased flow from causing a certain protective air flow to be too small, resulting in the failure of the protective air function. At the same time, valves 8 are provided at both ends of the flow-limiting orifice plate 7 on the protective air branch line 2. The protective air branch line 2 is connected to the protective air auxiliary pipeline 1 9, and the protective air auxiliary pipeline 1 9 is provided with a valve 8. When the flow-limiting orifice plate 7 is blocked, the valves 8 at both ends of the flow-limiting orifice plate 7 can be closed and the valve 8 on the protective air auxiliary pipeline 1 9 can be opened to cut the flow-limiting orifice plate 7 out of the protective air branch line 2. This can not only clean the flow-limiting orifice plate 7, but also ensure the normal transmission of the protective air.
[0030] Example 4
[0031] On the basis of Example 1, Figure 1As shown, a filter 10 is provided on the protective air main pipeline 3 to filter mechanical impurities such as rust carried in the protective air main pipeline 3 to prevent them from clogging the flow-limiting orifice 7. Furthermore, valves 8 are provided at both ends of the filter 10 on the protective air main pipeline 3. The protective air main pipeline 3 is connected to a second protective air auxiliary pipeline 11, which is also provided with a valve 8. When it is necessary to clean the filter 10, the valves 8 at both ends of the filter 10 can be closed and the valve 8 on the second protective air auxiliary pipeline 11 can be opened, removing the filter 10 from the protective air main pipeline 3. This allows the filter 10 to be cleaned while ensuring the normal delivery of the protective air.
