Device and method for online removal of salt deposited at bottom of hazardous waste incineration pickling tower

The invention provides an online removing device and method for salt accumulated at the bottom of a pickling tower. The online removing device for the accumulated salt at the bottom of the pickling tower comprises a pollution discharge flow guide surface, a circulating liquid disturbance device and a process logic control device, wherein the pollution discharge flow guide surface is used for guiding salt-containing waste liquid at the bottom of the pickling tower to be discharged; the circulating liquid disturbance device is used for spraying compressed air to circulating liquid at the bottom of the pickling tower for disturbance; and the process logic control device is connected with the compressed air spray gun switch air valve and is used for controlling the spraying of the compressed air spray gun. The salt accumulation amount at the bottom of the pickling tower can be effectively reduced, and the blocking frequency of a circulating pipeline and a spray gun is reduced. 本发明提供一种酸洗塔底部积盐在线去除装置和方法。所述酸洗塔底部积盐在线去
