The application relates to the technical field of chemical equipment, and particularly discloses an integrated gas-
solid separation waste acid regeneration
cracking furnace, which comprises a furnace body, a
combustion cavity arranged in the furnace body, a plurality of first baffles and second baffles arranged in the
combustion cavity, the first baffles and the second baffles being alternately arranged at equal intervals along an axis of the furnace body to form a baffle channel, a gas-
solid separator connected to an outlet end of the furnace body and comprising an outer
pipe and an inner
pipe coaxially arranged and provided with a flow guide
assembly, an induced draft fan arranged at an end of the gas-
solid separator away from the furnace body, and a
control system for detecting the pressure in the furnace body through a pressure
transmitter and adjusting the rotating speed of the induced draft fan by adopting a
PID control algorithm to maintain a micro-negative pressure state in the furnace body. The application realizes accurate control of the pressure in the
cracking furnace and efficient gas-solid separation, improves the waste acid regeneration efficiency and the equipment operation stability, and reduces environmental
pollution and
energy consumption.
