Problems solved by technology

However, since it is difficult for the cyclone dust collector to capture all the burning fuel particles, the leaked burning fuel particles entering the bag filter may ignite the bag and cause combustion.
For this reason, accidents of bag filter fires occur from time to time

Embodiment Construction

[0021] see figure 1 , which is a structural schematic diagram of the fire arresting device of the present invention. The dust removal system of the biomass boiler of the present invention includes a cyclone dust collector, a fire arresting device and a bag dust collector connected in sequence through a smoke pipe 100 . The flame arresting device includes a housing 210 , a flange 220 and a filter screen 230 , and the housing 210 includes an air inlet 211 and an air outlet 212 . The outlet end of the cyclone dust collector is provided with a smoke pipe 100, and the end of the smoke pipe 100 is set as an enlarged conical pipe 110 connected to the inlet end 211 of the fire arresting device, and the outlet end 212 of the fire arresting device passes through another section of smoke pipe 100 Connect with bag filter.

[0022] Specifically, the housing 210 is cylindrical, and its two ends are respectively connected to the smoke pipe 100 through flanges 220 . The filter screen 230 i...

Abstract

The invention relates to a flame-retardant device for a bag-type dust remover of a biomass boiler, which is connected between a cyclone dust collector and a bag type dust collector. The flame-retardant device comprises a shell and a filter net, wherein the shell comprises an air inlet end and an air outlet end, and the air inlet end and the air outlet end are respectively connected with a cyclone dust remover and the bag-type dust remover; and the filter net is fixed in the shell and is of a column shape. According to the flame-retardant device and a dust removal system, by arranging the filter net in front of the bag-type dust remover, combustible particles can be effectively prevented from entering the bag-type dust remover, the structure is simple, and the manufacturing cost is low; and by arranging the column-shaped filter net, the circulation area of flue gas is effectively increased; and the sizes of meshes of the filter net are reasonably designed, so that the resistance caused by the filter net to the circulation of flue gas is reduced.

Description

technical field [0001] The invention relates to boiler equipment, in particular to a fire arresting device and a dust removal system of a bag filter for a biomass boiler. Background technique [0002] Biomass boilers refer to boilers that use biomass energy as fuel. Due to its advantages of burning renewable fuel-biomass and ecological zero emissions, biomass boilers are gradually being widely used in many fields, including: household heating, small power plants, etc. Biomass boiler system usually includes feeding system, combustion system, soot blowing system, flue air system and automatic control system. The flue air system includes an air supply system and a dust removal system. The function of the dust removal system is that, under the action of the induced draft fan, the high-temperature flue gas generated after the combustion is completed enters the dust collector for purification through convective heat exchange in the flue pipe, and finally passes through the induce...
