Description

Technical Field

[0001] This utility model relates to the field of ignition technology for hydrogen chloride synthesis furnaces, and in particular to a visual integrated explosion-proof safety ignition device for hydrogen chloride synthesis furnaces. Background Technology

[0002] An explosion-proof ignition device is a specialized device designed for safe ignition in hazardous environments containing flammable or explosive gases or dust. These devices employ a series of explosion-proof measures to ensure that no explosion or fire will occur during the ignition process, thereby protecting production safety and personnel safety.

[0003] Existing hydrogen chloride synthesis furnaces lack explosion-proof design during ignition, posing certain safety hazards and posing a high risk of explosion during ignition and operation. Traditional ignition methods lack real-time visual monitoring, requiring personnel to perform ignition at close range in a hazardous environment, increasing the risk of accidents due to sudden changes in the on-site environment. To address these issues, we have developed a visual integrated explosion-proof safety ignition device for hydrogen chloride synthesis furnaces. Utility Model Content

[0004] This utility model discloses a visual integrated explosion-proof safety ignition device for a hydrogen chloride synthesis furnace, aiming to solve the safety hazards that exist in the ignition and operation of hydrogen chloride synthesis furnaces, which are prone to explosion accidents. Traditional ignition methods lack real-time visual monitoring mechanisms, requiring personnel to perform ignition at close range in a dangerous environment, which poses a technical problem of safety accidents caused by sudden changes in the on-site environment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A visual integrated explosion-proof safety ignition device for a hydrogen chloride synthesis furnace includes a housing. A fixing frame is located inside the housing. A gas inlet is located at the top of the housing, and an air inlet is located on one side of the top of the housing. The gas inlet and air inlet work together. A temperature-resistant and corrosion-resistant alloy tube is fixedly connected to the top of the housing. A flame stabilizer is located inside the temperature-resistant and corrosion-resistant alloy tube. The flame stabilizer works together with the gas inlet. A dedicated flame nozzle is fixedly connected to the top of the flame stabilizer. The flame stabilizer and the dedicated flame nozzle work together. A temperature-resistant and corrosion-resistant alloy electrode is fixedly connected inside the temperature-resistant and corrosion-resistant alloy tube and above the dedicated flame nozzle.

[0007] In a preferred embodiment, the mounting bracket houses an ignition high-voltage transformer and a video camera.

[0008] In a preferred embodiment, the outer side of the housing is provided with an electrical wiring port.

[0009] In a preferred embodiment, the outer side of the housing is provided with an electrical wiring port.

[0010] In a preferred embodiment, the outer side of the housing is coated with stainless steel, and the portion inserted into the furnace is made of tantalum and Hastelloy.

[0011] In a preferred embodiment, the video camera is powered by VDC.

[0012] The visual integrated explosion-proof safety ignition device for hydrogen chloride synthesis furnace provided by this utility model has the following advantages:

[0013] The intelligent, integrated explosion-proof design combines flame detection and ignition gun into one unit, making it robust, reliable, and requiring minimal on-site maintenance. Internal high-voltage electrodes provide ignition, eliminating the need for external high-voltage cables and ensuring safety. Hydrogen and air ignite internally within the ignition gun, with adjustable gas flow, unaffected by the furnace's internal airflow environment. This visual ignition method is relatively safe, preventing personnel from being at close range and potentially endangering themselves. Attached Figure Description

[0018] The above technical solution addresses the safety hazards posed by the hydrogen chloride synthesis furnace during ignition and operation, which could easily lead to explosions. Traditional ignition methods lack real-time visual monitoring, requiring personnel to perform ignition at close range in a hazardous environment, increasing the risk of accidents due to sudden changes in the on-site environment. To address these issues, the specific operation is as follows:

[0019] Reference Figure 1 In a preferred embodiment, the hydrogen inlet pressure of the ignition device is typically 0.05–0.1 MPa, and the hydrogen pressure can be controlled by a manual regulating valve on the hydrogen pipeline. The air inlet pressure of the igniter is typically 0.1–0.2 MPa, and the air pressure can be controlled by a manual regulating valve on the air pipeline to ensure that the flame length is within the range of 900–1000 mm and the flame shape is good, so that the flame detector can function properly. The ignition procedure should be to activate the igniter first, and then introduce hydrogen and air.

[0020] Working principle: First, the ignition device needs to be installed. Installation method:

[0021] 1.1 The HYG(F) type integrated ignition device shall be installed according to the installation drawings provided by the synthesis furnace manufacturer. After the ignition gun is installed in the corresponding position, it shall be fixed to the corresponding flange seat of the synthesis furnace ignition door with bolts, relying on the flange on the outer tube of the ignition gun. The fixing shall be reliable and the bolts shall not be loose.

[0022] 1.2 After the integrated ignition device is fixed, the corresponding air metal pipe and hydrogen metal pipe should be connected. The fixing should be reliable and there should be no gas leakage.

[0023] 1.3 The ignition control box shall be fixed by Party A in a safe, reliable, moisture-proof, and easily operable and observable location.

[0024] 1.4 Connect the cable wires according to the wiring diagram of the ignition control box.

[0025] To ensure safe and reliable ignition of the integrated ignition device, stable flame, and reliable flame detection, an ignition test is necessary before commissioning. Based on the characteristics of hydrogen, the hydrogen and air pressures at the ignition device inlet should be carefully adjusted.

[0026] 2. Start using the ignition device:

[0027] 2.1 The hydrogen inlet pressure of the ignition device is usually 0.05 to 0.1 MPa. The hydrogen pressure can be controlled by a manual regulating valve on the hydrogen pipeline.

[0028] 2.2 The air inlet pressure of the igniter is usually 0.1 to 0.2 MPa. The air pressure can be controlled by a manual regulating valve on the air pipeline to keep the flame length within the range of 900 to 1000 mm and ensure a good flame shape so that the flame detector can work normally.

[0029] 2.3 The ignition procedure should be to activate the igniter first, and then introduce hydrogen and air.
