Automatic ignition system and method for synthesis furnace

Abstract

The invention discloses an automatic ignition system and method for a synthesis furnace. The system comprises the synthesis furnace, an ignition device and at least one flame monitoring device; the ignition device comprises an ignition control box, a gas control cabinet, an ignition gun, a first cable, a hydrogen delivery pipe and an air delivery pipe; the flame monitoring device comprises an electric control box, a flame detector and second cables; and the wall of the synthesis furnace is provided with an ignition device fixing frame and a flame monitoring device fixing frame, and the ignition gun and the flame detector are fixed to the ignition device fixing frame and the flame monitoring device fixing frame respectively. The method includes the steps of installing the ignition gun, theignition control box and the gas control cabinet; connecting the ignition control box with the gas control cabinet, the gas control cabinet with the ignition gun, and the ignition gun with the ignition control box; installing and connecting the electric control box and the flame detector; introducing air and introducing hydrogen; performing energization for ignition; and performing temperature andflame monitoring. The automatic ignition system and method have the advantages of being simple, low in failure rate, high in ignition success rate, capable of realizing automatic control and the like, and are safe and reliable, and the service life reaches 15 years or longer.

Description

technical field [0001] The invention belongs to the field of ignition equipment for synthesis furnaces, and in particular relates to an automatic ignition system and method for synthesis furnaces. Background technique [0002] When hydrogen chloride is synthesized, hydrogen needs to be ignited first, and then reacted with chlorine. Since hydrogen needs to be ignited in the synthesis furnace first, the working conditions are more complicated, manual operation is more inconvenient, the success rate of ignition is low, and there is also great safety. Hidden dangers, at present, there are also automatic ignition guns for ignition, such as the patent No. 201410516503.4, which discloses an automatic ignition system for a hydrogen chloride synthesis furnace and its control method, including an ignition gun and a flame set on the side of the hydrogen chloride synthesis furnace furnace mouth The monitor and the chlorine gas inlet pipeline, the hydrogen gas inlet pipeline and the nitr...

[0002] When hydrogen chloride is synthesized, hydrogen needs to be ignited first, and then reacted with chlorine. Since hydrogen needs to be ignited in the synthesis furnace first, the working conditions are more complicated, manual operation is more inconvenient, the success rate of ignition is low, and there is also great safety. Hidden dangers, at present, there are also automatic ignition guns for ignition, such as the patent No. 201410516503.4, which discloses an automatic ignition system for a hydrogen chloride synthesis furnace and its control method, including an ignition gun and a flame set on the side of the hydrogen chloride synthesis furnace furnace mouth The monitor and the chlorine gas inlet pipeline, the hydrogen gas inlet pipeline and the nitrogen gas pipeline connected in series at the bottom of the furnace mouth of the hydrogen chloride synthesis furnace at the same time, this structure makes it necessary to purge with nitrogen before turning on the ignition gun, and multiple purges are required In order to avoid the corrosion of the electrodes, etc., in order to avoid the entrainment of nitrogen in the synthetic hydrogen chloride gas, the purity of the hydrogen chloride gas is affected, and the operation process is more complicated. When the ignition gun is turned on, air must be introduced into the entire furnace body. They are all filled with air, and then hydrogen gas is introduced to ignite. At the same time, flame detection needs to be repeated many times, and the flame detection adopts the method of temperature monitoring, which cannot directly show whether the ignition is successful. There is a great possibility of dangerous gas leakage, resulting in certain safety hazards
