Abstract

The invention discloses a fire prevention device for a front feed device of a biomass electricity generation furnace. The fire prevention device comprises a storage bin bracket and a storage bin body, wherein one side of the storage bin bracket is provided with a staircase, a closed conveying device is arranged on the storage bin bracket and is communicated with a shaftless screw conveyer by an articulated chute, and the front feed device is arranged on the storage bin body and is matched with the closed conveying device. The fire prevention device is characterized in that a fire prevention device body is arranged on the articulated chute. Furthermore, the fire prevention device body comprises a valve body, the upper end and the lower end of the valve body are respectively an inlet and an outlet, a bearing is arranged on one side surface at the upper part of the valve body, a rotating shaft is arranged on the bearing, and a normally closed type closing device is arranged on the rotating shaft. According to the fire prevention device, the effects of fire prevention and automatic unloading are achieved all the time, no resource is consumed in the running process, and economical efficiency and energy conservation are achieved. In addition, the fire prevention device is simple in structure, convenient to manufacture and low in maintenance cost.

Description

technical field [0001] The invention belongs to the field of biomass power generation equipment, and in particular relates to a fire prevention device for a feeding device in front of a biomass power furnace. Background technique [0002] Biomass is a substance that exists widely on the earth, including all animals, plants and microorganisms, as well as many organic matters derived, excreted and metabolized by these living substances. Because these biomasses have a certain amount of energy, and compared with conventional energy sources, these energies have the characteristics of high volatility, low energy density, and easy slagging during combustion, so the utilization of biomass has attracted more and more attention. [0003] The biomass direct combustion power generation system is to cut and crush the collected biomass materials such as straws into short rods of a certain length, or directly send them to the silo in front of the furnace, or press them into block-shaped or...
