Boiler flue dust deposition observing device

Abstract

The invention discloses a boiler flue dust deposition observing device. The boiler flue dust deposition observing device comprises a plurality of observing windows which are arranged at intervals in the flue gas progressing direction, wherein the observing windows comprise connection cylinders correspondingly and fixedly arranged in through holes of the flue side wall and connection disks fixedly connected to the connection cylinders; outer spigots are formed in the outer sides of central holes of the connection disks; glass sheets are clamped and embedded in the outer spigots; LED lamp strips or lamp beads are laminated on the glass sheets or the connection disks and are used for lighting the inside of the flue; a plurality of pressing mechanism are uniformly distributed on the connection disks and are used for pressing the glass sheets and the connection disks. Through the boiler flue dust deposition observing device, the plurality of observing windows are arranged in the flue, are located after injection points and are distributed along the flue gas progressing direction; the droplet evaporation status can be effectively observed and evaluated by observing at a plurality of points; meanwhile, the observing effect is further improved due to adoption of the manner of lighting the inner sides of the glass sheets.

Description

technical field [0001] The invention relates to the technical field of flue dust removal, in particular to a boiler flue dust observation device. Background technique [0002] The desulfurization wastewater flue evaporation zero-emission process is widely used in power plants around the world. Because the flue gas in the flue evaporation process of desulfurization wastewater comes from the outlet of the air preheater, the temperature of the flue gas is usually 130 ° C ~ 160 ° C, and the water content of the desulfurization wastewater is relatively high (not less than 95%); in order to avoid harm to the inner wall of the flue and subsequent dust removal equipment, it is required to ensure that the waste water droplets are completely evaporated in the flue, but the power plant is limited by the existing space and structure, and the length of the flue for spray evaporation is very long limited. How to observe whether the liquid in the flue is completely evaporated and the evap...
