The utility model discloses a fan pressurization adjusting device which comprises a pressurization
machine, a gas flow rate sensor is installed at the gas inlet end of the pressurization
machine, and an adjusting structure is installed at one end of the gas flow rate sensor. In a
normal state, a reinforcing part is closed, the flow rate of
coal gas is adjusted through an adjusting valve, if the flow rate value is smaller than the minimum
limit value of the adjusting valve, the reinforcing part works, namely, a driving
assembly works, under connection of a driven
bevel gear, a rotating rod rotates on a fixed sleeve through a bearing, and fan blades rotate accordingly; and the gas flow flowing through the connecting
pipe is accelerated and pressurized until the gas flow rate sensor detects that the gas flow rate reaches a standard value, so that the normal work of the pressurizing
machine is ensured, the shutdown of the pressurizing machine is avoided, the sufficient
gas supply is ensured, the normal work of the
combustor is ensured, the
combustion efficiency is ensured, the required temperature is reached, and the continuity of industrial production and the product quality are ensured.
