Description

Technical Field

[0001] This utility model relates to the field of waste gas and waste liquid incinerator technology, specifically to a waste gas and waste liquid incinerator with multiple burners. Background Technology

[0002] The coal-to-ethylene glycol process generates a large amount of waste gas and waste liquid containing harmful substances, which need to be incinerated to meet environmental emission standards. Current incinerators for treating these waste gases and liquids are typically equipped with only one burner; however, this single-burner incinerator has significant limitations. Firstly, the combustion capacity of a single burner is limited, making it difficult to meet the incineration needs of a large volume of waste gas and waste liquid, resulting in low treatment efficiency and an inability to promptly process the waste gas and waste liquid generated in the process. Secondly, when the single burner fails, the entire incinerator must be shut down for repairs. Since the waste gas and waste liquid incinerator also co-produces steam for power generation or serves as a heat source for reboilers, preheaters, and dryers, a shutdown of the incinerator severely impacts the normal operation of power generation, distillation, and drying units, making continuous production difficult and causing significant economic losses for the company. Therefore, there is a need for an incinerator that can increase combustion capacity and continue operating even when a single burner fails. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing incinerators with single burners, such as limited combustion capacity and easy shutdown due to damage to a single burner. It provides a waste gas and waste liquid incinerator with multiple burners to increase combustion capacity, ensure normal operation of the incinerator even when individual burners are damaged, and improve production continuity.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waste gas and waste liquid incinerator with multiple burners, comprising an incinerator body, wherein at least two burners are provided on the incinerator body, and each burner is provided with a shut-off valve to disconnect each burner from the incinerator body; the burners are respectively connected to a waste gas inlet pipe, a waste liquid inlet pipe and an air inlet pipe, and each burner is provided with an independent control valve; it also includes a control system, which is connected to each burner and the control valve, and is used to control the start-up and shutdown and operating parameters of each burner.

[0005] The number of burners is 2-4, evenly distributed on the side wall of the incinerator body. This distribution method can make the waste gas and waste liquid burn more completely in the incinerator and improve the incineration efficiency.

[0006] Both the exhaust gas inlet pipe and the waste liquid inlet pipe are equipped with flow metering devices, which are connected to the control system. This allows the control system to adjust the burner's operating parameters according to the flow rate, ensuring optimal combustion performance.

[0007] The incinerator body is equipped with a temperature sensor, which is connected to the control system. The control system can adjust the operating status of the burner in real time according to the temperature inside the furnace to ensure that the incineration temperature meets the requirements.

[0008] The incinerator body is equipped with a slag discharge port at the bottom, and a sealing door is provided at the slag discharge port to facilitate timely cleaning of the waste slag generated during incineration, while ensuring the airtightness of the incinerator. Compared with the prior art, the present invention has the following beneficial effects: 1. The use of multiple burners greatly increases the combustion capacity of the incinerator, which can meet the incineration requirements of a large amount of waste gas and waste liquid in the coal-to-ethylene glycol process and improve the treatment efficiency.

[0009] 2. Each burner has an independent control valve and control system. When an individual burner is damaged, that burner can be shut down for maintenance while the other burners can continue to work normally. This avoids a complete shutdown of the incinerator, ensures the continuity of production, and reduces economic losses.

[0010] 3. The burners are evenly distributed, and combined with flow metering devices and temperature sensors, they can ensure more complete combustion of waste gas and waste liquid, guaranteeing incineration effect and meeting environmental protection requirements. Attached Figure Description

[0012] refer to Figure 1 The present invention will now be described in further detail with reference to specific embodiments.

[0013] A waste gas and waste liquid incinerator with multiple burners includes an incinerator body 1, which is made of high-temperature resistant material to withstand the high-temperature incineration environment. Three burners, A2, B3, and C4, are arranged in a triangular pattern on the side wall of the incinerator body 1 for more uniform combustion. Each burner is equipped with a shut-off valve to disconnect it from the incinerator body 1. Each burner is connected to a waste gas inlet pipe, a waste liquid inlet pipe, and an air inlet pipe. The waste gas inlet pipe transports waste gas generated from the coal-to-ethylene glycol process, the waste liquid inlet pipe transports waste liquid generated from the process, and the air inlet pipe transports the air required for combustion. Each burner's corresponding waste gas inlet pipe and waste liquid inlet pipe is equipped with an independent control valve, which is either a solenoid valve or a pneumatic valve, allowing for precise control of the feed rate. Each burner also has an ignition rod and a natural gas pipe, which transports natural gas for ignition and for supplementing heat.

[0014] The incinerator also includes a control system, which is a PLC-based system connected to each burner and control valves. The control system can control the start and stop of each burner, as well as adjust operating parameters such as combustion power.

[0015] Both the exhaust gas inlet pipe and the waste liquid inlet pipe are equipped with flow metering devices, which are turbine flow meters. The flow metering devices are connected to the control system and can transmit the feed flow information to the control system in real time. The control system adjusts the opening of the control valve and the operating parameters of the burner according to the flow information.

[0016] Multiple temperature sensors, which are thermocouple sensors, are installed at different locations inside the incinerator body 1. These sensors are connected to the control system and provide real-time feedback of the furnace temperature information. When the furnace temperature is too high or too low, the control system automatically adjusts the burner's operating status to maintain the furnace temperature within a suitable combustion temperature range.

[0017] The incinerator body 1 has a ash discharge port 5 at its bottom, and a sealing door at the ash discharge port 5. The sealing door is made of high-temperature resistant sealing material and is normally closed to ensure the airtightness of the incinerator. When it is necessary to clean the ash, the sealing door can be opened to discharge the ash.

[0018] When this multi-burner waste gas and waste liquid incinerator is in operation, the control system activates a corresponding number of burners based on the required volume of waste gas and waste liquid to be processed. The feed rates of waste gas and waste liquid are regulated by control valves, and the burners incinerate the incoming waste gas and waste liquid. During incineration, flow metering devices and temperature sensors monitor relevant parameters in real time and provide feedback to the control system. The control system adjusts the burners and control valves promptly based on the feedback information to ensure complete and efficient incineration. When a burner malfunctions, the control system closes the corresponding control valve, stopping the burner's operation. The control system also closes the shut-off valve connecting the burner to the incinerator body 1, disconnecting the burner from the incinerator body 1. Other burners continue to operate, allowing maintenance personnel to repair the faulty burner without affecting the overall operation of the incinerator.

[0019] Another embodiment differs from Embodiment 1 in that two burners are provided on the side wall of the incinerator body 1, and the two burners are symmetrically distributed.

[0020] Another embodiment differs from Embodiment 1 in that four burners are provided on the side wall of the incinerator body 1, and the four burners are evenly distributed.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
