Abstract
The utility model discloses a kind of biomass boiler solid fuel material inlet automatic fire extinguisher, comprise controller, sensor and magnetic valve, and fire main, in the feeding mouth position of boiler, heat-sensitive sensor is installed, in the upside of boiler conveying pipeline inner wall at end, drencher is installed, pipeline is provided with magnetic valve; The holding wire of described heat-sensitive sensor is connected with the input of controller, and the output of controller is connected with the control end of corresponding magnetic valve.The utility model by sensor sensing boiler feeding mouth temperature, and takes water curtain to isolate automatically in time, feeding pipe and thermal source is isolated in time, stops the generation of fire or spread.Its structure is simple, automatically controls buffer action, can reduce consumption difficulty and cost, can not cause boiler shutdown problem.The gas circuit of scheme is closed and can be isolated thermal source further as a supplement, cooling fire prevention.
Description
Technical field
The utility model relates to boiler of power plant technical field of fire control, is specifically related to a kind of biomass boiler solid fuel material inlet automatic fire extinguisher.
Background technology
The fuel inlet temperature of boiler of power plant is higher, and solid fuel enters boiler internal by feeding pipe from fuel inlet, and due to pot in-furnace temperature height changing factor, the solid fuel that may ignite in feeding pipe when being in the condition of high temperature, exists potential safety hazard.Traditional boiler fire-fighting method is outer at whole boiler and feeding device is outside equipped with fireproof isolating door, once there is fire problem, closes fireproof isolating door immediately, thus isolated air is put out a fire.There is complex structure in this mode, realizes cost greatly highly difficult, and to cause in boiler also Fire-fighting Problems simultaneously after fire extinguishing, shutdown can cause huge economic loss.
Utility model content
The purpose of this utility model is for problems of the prior art and deficiency, provides a kind of biomass boiler solid fuel material inlet automatic fire extinguisher.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of biomass boiler solid fuel material inlet automatic fire extinguisher, comprise controller, sensor and magnetic valve, and fire main, in the feeding mouth position of boiler, heat-sensitive sensor is installed, in the upside of boiler conveying pipeline inner wall at end, drencher is installed; Drencher is connected with fire-fighting bye-pass, and fire-fighting bye-pass is connected with fire main pipe road, and is provided with magnetic valve on pipeline; The holding wire of described heat-sensitive sensor is connected with the input of controller, and the output of controller is connected with the control end of corresponding magnetic valve.
Also be provided with Beck-up Control System, the holding wire of described sensor is connected by 4 tunnel bilateral transmitters with between controller and spare controller.
Show hand-operated valve with described magnetic valve.
The bottom of described feeding pipe end is also provided with valve, and is communicated with gas circuit by tracheae, and tracheae is provided with gas solenoid, and the control end of gas solenoid is connected with the output of described controller or spare controller.
Beneficial effect: the utility model by sensor sensing boiler feeding mouth temperature, and takes water curtain to isolate automatically in time, feeding pipe and thermal source is isolated in time, stops the generation of fire or spread.Its structure is simple, automatically controls buffer action, can reduce consumption difficulty and cost, can not cause boiler shutdown problem.The gas circuit of scheme is closed and can be isolated thermal source further as a supplement, cooling fire prevention.The utility model is simple and reasonable, and result of use is very good.
