Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a hydrogen chloride synthesis furnace with a flame ultraviolet detector. Background Technology

[0002] The hydrogen chloride synthesis furnace mainly utilizes hydrogen and chlorine gases for combustion within a sealed furnace body. The flame temperature is around 1100 degrees Celsius, and the furnace pressure is slightly positive. The produced hydrogen chloride gas serves as a raw material for subsequent production. Determining whether combustion is occurring during production relies on ultraviolet (UV) detection using a flame detector. The presence or absence of UV light indicates whether the flame is burning. In the hydrogen chloride synthesis process, thorough and uniform mixing of hydrogen and chlorine is crucial for ensuring efficient reaction and improving product purity. It directly affects the stability and state of subsequent combustion. Insufficient mixing and abnormal flame conditions, if not detected promptly, can lead to serious safety accidents. Therefore, it is necessary to ensure thorough gas mixing before combustion and to monitor the flame's combustion status in a timely manner to guarantee the safety of the hydrogen chloride synthesis furnace during operation. Thus, a hydrogen chloride synthesis furnace equipped with a flame UV detector is needed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a hydrogen chloride synthesis furnace with a flame ultraviolet detector to solve the problem of combustion safety in the prior art hydrogen chloride synthesis furnace.

[0004] To achieve the above and other related objectives, this utility model provides a hydrogen chloride synthesis furnace with a flame ultraviolet detector, comprising:

[0005] An air intake section is connected to an external air source. The air intake section includes an oxygen section and a gas mixing section. The gas mixing section is provided with a hydrogen inlet and a chlorine inlet. A hydrogen equalization chamber connected to the hydrogen inlet is provided on the lower side of the air intake section for uniformly introducing hydrogen into the gas mixing section. A chlorine equalization chamber connected to chlorine is provided on the upper side of the air intake section for uniformly introducing chlorine into the gas mixing section.

[0006] The combustion furnace body is located above the air inlet. A combustion plate communicating with the air inlet is provided inside the combustion furnace body. An ultraviolet detector is provided on the side wall of the combustion furnace body above the combustion plate to detect the flame condition at the combustion plate.

[0007] By setting up an oxygen section and a mixing section on one side of the air intake, oxygen, hydrogen, and chlorine are continuously supplied to the air intake, ensuring a continuous gas supply. The mixing section has separate hydrogen and chlorine inlets, allowing for independent gas supply or shut-off. The gas supply status can be adjusted promptly during use to ensure safety. The hydrogen and chlorine equalization chambers ensure uniform hydrogen and chlorine entering the mixing section, guaranteeing homogeneous gas mixing and improving combustion efficiency. An ultraviolet detector monitors the combustion at the combustion plate, determining whether the flame is burning and ensuring combustion safety.

[0008] To avoid misjudgments common in traditional UV detection, the UV detection here uses an analog signal acquired by a visible light sensor. After amplification and filtering, the signal is converted into a digital signal by an AD converter chip. The flame detector then performs photoelectric conversion, followed by a multi-stage amplification circuit to convert it into a 0-5V voltage signal. The maximum non-adjustable error is ±1LSB. Sampling is performed by an 8-bit successive approximation AD converter chip with a clock frequency range of 10-1280kHz. When the clock frequency is 500kHz, the conversion time is within 128µs, and the power consumption is 15mW, which is sufficient to meet the speed requirements. Zero-point and full-scale adjustments are unnecessary. The converted digital signal is sent to the intelligent microprocessor, which filters and performs range conversion. The final value displayed on the LCD screen is a number between 0 and 100, reflecting the size of the flame. By observing these numbers, the size of the flame can be intuitively determined. Conventional flame detectors only have an electric shock output indicating the presence or absence of a flame. The flame detector we selected has both a trigger relay output, a 4-20mA output, and an alarm output to meet the needs of different users.

[0009] In one embodiment of the present invention, a hydrogen equalization hole is provided on the side of the hydrogen equalization chamber that is connected to the gas mixing section, and the hydrogen equalization hole is evenly arranged on the upper side of the hydrogen equalization chamber.

[0010] In order to uniformly disperse hydrogen before it enters the mixing section, hydrogen distribution holes are evenly arranged on the upper side of the hydrogen distribution chamber, thereby improving the uniformity of hydrogen entering the mixing section.

[0011] In one embodiment of the present invention, a chlorine gas equalization hole is provided on the side of the chlorine gas equalization chamber that is connected to the gas mixing section, and the chlorine gas equalization hole is evenly arranged on the lower side of the chlorine gas equalization chamber.

[0012] In order to uniformly disperse chlorine gas before it enters the mixing section, chlorine gas equalization holes are evenly arranged on the upper side of the chlorine gas equalization chamber, thereby improving the uniformity of chlorine gas entering the mixing section.

[0013] In one embodiment of the present invention, the air inlet is provided with a flow-slowing seat extending to the lower side of the combustion furnace body, and the combustion furnace body is arranged perpendicular to the flow-slowing seat.

[0014] By setting up a flow buffer, oxygen, hydrogen, and chlorine can be further mixed, ensuring the uniformity of the gases to be burned and preventing the gas flow rate from being too fast, thus ensuring complete combustion.

[0015] In one embodiment of the present invention, a flow guide seat is provided on the side of the combustion furnace body connected to the flow slowing seat. The flow guide seat is a funnel-shaped flow guide seat, and the open end of the flow guide seat is positioned facing the flow slowing seat.

[0016] The design of the flow guide can concentrate the flow of gas, thereby ensuring complete combustion.

[0017] In one embodiment of the present invention, the flow guide seat is located below the combustion plate, and a flange connection seat is provided between the bottom of the flow guide seat and the flow slowing seat. An ignition seat is provided on one side of the flow guide seat, and an igniter connected to the combustion plate is provided on the ignition seat. The bottom of the igniter extends to the outside of the flange connection seat.

[0018] A flange connection seat is provided between the bottom of the flow guide seat and the flow buffer seat, which facilitates the disassembly of the flow guide seat and the assembly of the igniter.

[0019] As described above, the hydrogen chloride synthesis furnace with a flame ultraviolet detector of this utility model has the following beneficial effects: The continuous supply of oxygen, hydrogen, and chlorine through the gas inlet section ensures a continuous gas supply; the separate hydrogen and chlorine inlets in the mixing section allow for independent gas supply or shut-off, enabling timely adjustment of the gas supply status during use and ensuring gas supply safety; the hydrogen and chlorine uniform gas chambers ensure uniform gas and chlorine entering the mixing section, thereby ensuring uniform gas mixing and improving combustion efficiency; and the ultraviolet detector detects the combustion status at the combustion plate, allowing for determination of whether the flame is burning, thus ensuring combustion safety.
