Description

Device for eliminating bag fire of bag-type dust collector of boiler

Technical Field

The utility model relates to a boiler dust removal technical field specifically is a device that eliminates boiler sack cleaner sack and catches fire.

Background

The boiler inevitably produces dust and flue gas in the in-process that uses, and the dust removal of boiler is exactly that the dust in the boiler is separated from the flue gas to reduce dust pollution and be favorable to further carrying out treatments such as desulfurization, denitration to the flue gas. With the development of society, environmental protection is more and more emphasized by people, and boiler dust removal is applied to various fields such as thermal power generation and the like.

Boiler flue gas flow: boiler → economizer → flue → cyclone → flue → bag dust collector → flue → induced draft fan → smoke window. The dust removing equipment adopted for removing dust in the boiler comprises a mechanical dust remover, a bag type dust remover, an electric dust remover, a wet dust remover and the like. However, each dust removal and purification system always has technical advantages and disadvantages, and proper dust removal facilities and processes should be selected according to actual conditions. Mechanical dust collectors generally refer to devices that use the action of mass forces (gravity, inertial, centrifugal, etc.) to separate particulate matter from a gas stream. It includes gravity settling chamber, inertial dust remover and cyclone dust remover. The bag type dust collector is a dust removing and purifying facility, wherein dust-containing gas enters a cylindrical filter bag from the lower part, when passing through the pores of a filter material, dust is collected on the filter material, clean air penetrating through the filter material is discharged from an outlet, and the dust deposited on the surface of the filter material can fall off from the surface of the filter material under the action of mechanical vibration and finally falls into an ash hopper. The electric dust collector is a dust removing device which makes dust particles charged in the process of separation through a high-voltage electric field, and makes the dust particles gathered on a dust collecting plate to separate dust from dust-containing gas under the action of the electric field force. A wet dust collector is a dust collecting apparatus which separates dust from a dust-containing gas by bringing the dust-containing gas into close contact with a liquid (typically water) and capturing particles by inertial collision or chemical action of water droplets and the particles.

At present, when a boiler on the market is used, the flue gas generated by the boiler needs to be subjected to dust removal and purification, in actual use, when the flue gas generated by the boiler needs to be subjected to dust removal and purification, a bag-type dust remover is generally adopted to perform dust removal and purification on the flue gas generated by the boiler, and the temperature is too high before the flue gas generated by the boiler enters a bag for dust removal, and a small amount of sparks are generated, so that a bag in the bag-type dust remover catches fire easily, and a fire accident occurs.
