Background

The pure oxygen continuous gasification gas making furnace device is provided with a set of chimney device, and is used for safe pressure relief when a system is started or stopped or the system jumps suddenly, so that the safety and the controllability of the system are guaranteed. In the production, a gas making furnace adopts 20-40 mm coke particles or anthracite as a gasification raw material, and a small amount of light floating particulate matters (coke powder and coal powder) are carried in the coarse water gas after reaction and enter a subsequent system. Set up a cyclone behind the traditional gas making stove and be used for the desorption particulate matter, but the device is 90% to particulate matter desorption efficiency, still can have 10% particulate matter to send into the chimney behind the water gas along with, can not separate completely, causes the long-term operation in-process of system, and a large amount of deposition adheres to the pipeline inner wall.

The existing smoke abatement process flow has the following defects: 1) when the gas making furnace is stopped, the chimney is opened instantly, the system is reduced to 0kpa from 12kpa, the flow rate of water gas is accelerated, the accumulated dust attached to the pipeline falls off due to the scouring of air flow, and the water gas is discharged into the atmosphere along with the water gas through the chimney to cause the phenomenon of black smoke emission; 2) the residual 10% of particles after being removed by the cyclone separator are continuously discharged into the atmosphere through a chimney, so that the phenomenon of black smoke is caused; 3) when the gas making furnace is originally started, the phenomenon of black smoke is generated when materials such as firewood, engine oil and the like are ignited and the combustion is insufficient. Therefore, the device for eliminating black smoke emitted from the chimney of the gas making furnace is manufactured, and the problems that the existing chimney emits black smoke, the treatment is incomplete, and the coal powder influences water sealing to cause system pressure building are solved.
