Description

Float glass flue gas automatic ignition device Technical Field The utility model relates to the technical field of tail gas treatment, in particular to an automatic ignition device for float glass flue gas. Background In the float glass production process, the management of flue gas is critical. Because of the requirements of the production process, the gas needs to be continuously combusted in the kiln to maintain a high-temperature environment, however, in actual operation, the reduction of the flue temperature often leads to insufficient combustion of the gas, so that the waste gas contains high-concentration unburned gas. This is particularly the case during a fire change, which greatly increases the risk of a flue explosion. Conventionally, the method mainly relies on manual fire change operation and monitoring to solve the problems, and is low in efficiency and difficult to realize accurate control, so that safety accidents caused by too high gas content cannot be effectively prevented. The existing flue gas automatic ignition device has an automatic ignition function, and can burn CO gas in a flue through remote operation, so that the risk coefficient of workers in direct contact with harmful gas and a high-temperature environment is effectively reduced. However, the existing automatic ignition device for flue gas cannot fully consider the problems of convenient installation and detachability, so that the working strength of workers is increased in the actual use process, and the maintenance and overhaul efficiency is reduced. In addition, the manual opening ignition of staff is needed in each fire changing process of the conventional flue gas device, so that the flame size is difficult to accurately control, the operation risk is increased, and the risk of safety accidents is also improved. In addition, the existing flue waste gas ignition device cannot effectively extend into the flue and is tightly sealed, so that real-time data cannot be automatically collected to judge whether ignition is needed. This not only reduces the response efficiency of the device, but also increases the risk of safety accidents. For the problems in the related art, no effective solution has been proposed at present.
