The invention discloses a bypass structure and a using method thereof, and relates to waste gas treatment equipment. The bypass structure comprises a bypass pipe and a bypass valve. The bypass valve comprises: a mounting base, disposed in the bypass pipe and surrounding the bypass pipe by one cycle; a cover plate, arranged on the mounting base; a main shaft, arranged on one side of the cover plateand connected with the cover plate through a connecting rod, wherein the two ends of the main shaft penetrate through the bypass pipe, and a rotating arm is arranged at one end of the main shaft; andan air cylinder, arranged on the outer side of the bypass pipe, wherein a connector is arranged at the lower end of the air cylinder and connected with the rotating arm. The air cylinder can be arranged on the outer side of the bypass pipe, a telescopic rod of the air cylinder is prevented from penetrating through the pipeline, the abrasion problem caused by stretching and retracting of an air cylinder in an existing bypass structure is solved, and the sealing performance of the pipeline is guaranteed.
Description
technical field [0001] This application relates to the field of oil fume and waste gas treatment, in particular to a bypass structure and its use method. Background technique [0002] The bypass structure is one of the important structures in high-temperature and high-pressure waste gas treatment equipment, which is used to discharge high-temperature and high-pressure gas when the equipment is abnormal. For example, when excessive high-temperature and high-pressure gas accumulates in the equipment, it is easy to cause the temperature of the furnace to be much higher than the set temperature, which will cause the furnace to explode, so the excess gas needs to be released through the bypass structure. [0003] In this regard, as the Chinese utility model patent whose notification number is CN205815367U discloses "a dust collector bypass device", which includes a lifting cylinder and a bypass valve. The lifting cylinder passes through the flue and is connected to the bypass val...
