Dust collection system of petroleum coke calcining and cooling machine

Abstract

The invention aims to disclose a dust collection system of a petroleum coke calcining and cooling machine. The system comprises a cyclone dust collector, a bag-type dust collector and an induced draftfan, wherein the input end of the cyclone dust collector is connected with flue gas of a cooling agent, the cyclone dust collector is sequentially connected with the bag-type dust collector and the induced draft fan, and the output end of the cyclone dust collector and the output end of the bag-type dust collector are conveyed to a dust collection process belt through a shared screw. Compared with the prior art, the bag-type dust collector is additionally arranged for secondary filtering of smoke, and the filtered smoke can be directly exhausted into the atmosphere, so the environment is notpolluted, the problems that the negative pressure of a kiln head is low, accumulated dust of a flue and a boiler is corroded, cleaning is difficult and time is consumed can be solved, convenience andfeasibility are achieved, time is saved, cost is reduced, and the purpose of the invention is achieved easily under existing conditions.

Description

technical field [0001] The invention relates to a cooling machine dust collection system, in particular to a petroleum coke calcination cooling machine dust collection system. Background technique [0002] The dust-laden flue gas generated in the rotary kiln cooler is sucked out by the centrifugal fan of the cyclone dust collector, and the gas-solid separation occurs through the cyclone dust collector. The dust falls on the belt conveyor, and the flue gas is discharged into the combustion chamber of the rotary kiln through the pipe for re-combustion deal with. A U-shaped combustion chamber is installed behind the rotary kiln. The dust and volatile matter in the flue gas cannot be fully burned. Most of the dust is sucked into the boiler and desulfurization tower, and then discharged from the chimney to the atmosphere, causing environmental pollution. After entering the boiler, the dust adheres to the tube wall On the contrary, the boiler is blocked and the pressure loss is t...
