Description

Technical Field

[0001] The utility model relates to the technical field of synthesis furnace lamp holder cleaning devices, in particular to an automatic synthesis furnace lamp holder cleaning device. Background Art

[0002] The chlorine gas from chlorine compression enters the chlorine buffer tank after passing through the pressure regulating valve, and the pressure is controlled at 120KPa. Then it enters the synthesis furnace lamp holder through the flow meter, flow regulating valve, and chlorine flame arrester. The hydrogen gas from hydrogen compression enters the hydrogen buffer tank after passing through the pressure regulating valve, and the pressure is controlled at 85KPa. Then it enters the synthesis furnace lamp holder through the flow meter, flow regulating valve, and hydrogen flame arrester to react with chlorine to produce hydrogen chloride through combustion reaction, and then it is sent to the next process after cooling.

[0003] The main problems in this process are:

[0004] The alkaline mist contained in the hydrogen produced by electrolysis in the electrolyzer is not completely removed in the hydrogen treatment process, resulting in the formation of sodium chloride after it reacts with chlorine in the synthesis furnace. The sodium chloride formed during the operation accumulates at the lamp head due to the high temperature, blocking the hydrogen gas collection pipeline, making it difficult for hydrogen to enter, reducing the hydrogen flow rate, and causing excessive chlorine in the synthetic hydrogen chloride gas, resulting in the reaction of excessive chlorine with acetylene in the downstream process, generating chloroacetylene and releasing a large amount of heat, affecting the safe operation of the system. Summary of the invention

[0005] The utility model provides an automatic lamp holder cleaning device for a synthesis furnace, which overcomes the above-mentioned shortcomings of the prior art and can effectively solve the problem that the sodium chloride accumulated at the lamp holder of the synthesis furnace blocks the hydrogen gas collecting pipeline.

[0006] The technical scheme of the utility model is achieved through the following measures: an automatic lamp holder cleaning device for a synthesis furnace, comprising a lamp holder for a synthesis furnace, a hydrogen flame arrester, a chlorine flame arrester and a low-pressure steam pipe, wherein the hydrogen inlet end of the lamp holder for the synthesis furnace is fixedly connected with a hydrogen pipe, on which a hydrogen flame arrester is fixedly installed, the chlorine inlet end of the lamp holder for the synthesis furnace is fixedly connected with a chlorine pipe, on which a chlorine flame arrester is fixedly installed, the hydrogen pipe between the hydrogen flame arrester and the hydrogen inlet end of the lamp holder for the synthesis furnace is fixedly connected with a low-pressure steam pipe, the low-pressure steam pipe is connected with a shower guide, a shower guide solenoid valve is arranged on the shower guide, and a cleaning solenoid valve is serially connected to the low-pressure steam pipe between the shower guide and an outlet end of the low-pressure steam pipe.

[0007] The following are further optimizations and / or improvements to the above utility model technical solution:

[0008] The above-mentioned automatic lamp head cleaning device for the synthesis furnace may also include a controller, and the controller is electrically connected to the shower solenoid valve and the cleaning solenoid valve.

[0009] The controller may be a PLC controller or other existing publicly known industrial controllers.

[0010] The hydrogen pipe may be provided with a short buffer pipe corresponding to the outlet end of the low-pressure steam pipe, and the outlet end of the low-pressure steam pipe is fixedly connected to the upper end of the short buffer pipe.

[0011] The hydrogen pipe may be provided with a connection hole corresponding to the lower end of the buffer short tube, and the lower end of the buffer short tube is fixed at the connection hole.

[0012] The utility model has a reasonable and compact structure and is easy to use. Low-pressure steam is sent into the hydrogen pipe through a low-pressure steam pipe to remove sodium chloride crystals from the hydrogen gas collecting pipeline at the lamp head of the synthesis furnace and reduce the regeneration of sodium chloride as much as possible, thereby keeping the hydrogen gas collecting pipeline at the lamp head of the synthesis furnace unobstructed, ensuring the stability of the hydrogen inlet pressure and eliminating safety hazards.
