Feeding hopper fire extinguishing device suitable for garbage incinerator

Abstract

The invention relates to a feeding hopper fire extinguishing device suitable for a garbage incinerator. The feeding hopper fire extinguishing device suitable for the garbage incinerator is composed ofa main pipe, a water inlet pipe, a flange, a rubber cushion ring, a connecting bolt, a nut, a water outlet pipe, a nozzle and a supporting frame; the supporting frame is welded to a feeding hopper body to achieving fixing and supporting effects; the main pipe, the water inlet pipe, the flange, the water outlet pipe, the rubber cushion ring, the connecting bolt, the nut and the nozzle are assembled into a whole. According to the feeding hopper fire extinguishing device, the phenomenon of spontaneous combustion or even a fire disaster caused by high heat value of garbage is avoided, meanwhile,the feeding hopper fire extinguishing device is arranged at the edge of a feeding hopper, so descending channels of garbage are not occupied, it is ensured that the garbage is fed normally without being hung, and thus the normal and continuous operation of the incinerator is not affected, and the problem of the fire disaster caused by the spontaneous combustion of the garbage is solved.

Description

technical field [0001] The invention relates to the field of incineration, in particular to a fire extinguishing device for a feeding hopper applied to a garbage incinerator. Background technique [0002] The waste incineration method has become one of the main methods of urban waste disposal because of its remarkable reduction effect, land saving, elimination of various pathogens, and conversion of toxic and harmful substances into harmless ones. [0003] The garbage hopper, one of the auxiliary equipment of the garbage incinerator, is assembled from ordinary carbon steel. When the large-volume hopper is filled with garbage, it is easy to cause the garbage to spontaneously combust as the garbage ferments and the incineration smoke overflows. , a fire broke out. [0004] In order to prevent spontaneous combustion of garbage in the hopper, such as figure 1 As shown, a fire extinguishing device is usually installed in the middle of the feed hopper, mainly by inserting the wa...

AI Technical Summary

Problems solved by technology

[0005] However, such a design, while having a fire-extinguishing effect, also has certain hidden dangers.

When the garbage is thrown into the hopper and slides down the incline, it is easy to hang and stagnate on the water inlet pipe, resulting in unsmooth feeding. Over time, it is more likely to cause garbage bridging, affecting the normal operation of the incinerator, and even leading to shutdown Maintenance, increase power plant operating costs
