Catalyst adding device for inhibiting coking of biomass boiler

The utility model discloses a catalyst adding device for inhibiting biomass boiler coking, and relates to the technical field of biomass boiler combustion, the catalyst adding device for inhibiting biomass boiler coking comprises a storage tank, the top of the storage tank is communicated with a feed pipe, the rear side of the storage tank is communicated with a feed delivery pipe, and the feed delivery pipe is communicated with the feed pipe. The rear side of the conveying pipe communicates with a biomass boiler, a motor is fixedly connected to the left side of the storage tank, the right output end of the motor extends into the storage tank, the motor is started to drive a cylinder to rotate, and the cylinder rotates to drive a catalyst at an opening to rotate close to and away from an opening of the conveying pipe. And the work of equivalently adding the catalyst into the biomass boiler is completed, so that the catalyst is equivalently added, the situation that the dosage of the catalyst is unstable due t
