Abstract
The utility model relates to a flue gas humidifying device for a boiler. A circle of spiracles composed of uniformly distributed through holes are arranged on the cone-shaped wall of a contracted tube of a venturi tube, and a circle of spiracles composed of uniformly distributed through holes are also arranged on the peripheral wall of a throat tube. The external surface of the venturi tube is wrapped with a cylindrical housing of which the upper and the lower ends are separately connected to the contracted tube and a diffusion tube of the venturi tube. A water inlet tube connected with a water pump penetrates through the through holes on the housing and enters an interlayer. The lower part of the housing is provided with a discharge tube with a valve, wherein the discharge tube is connected with the interlayer. The utility model has the advantages of simple structure and good effects on eliminating smoke and dust.
Description
The utility model relates to a kind of device of boiler smoke abatement dedusting.
Venturi tube is widely used in the field of boiler smoke abatement dedusting by people at present.Its basic structure is: anemostat is a long truncated cone shape pipe, and collapsible tube is a cutting back conical pipe, and both are small-bore identical, by trunnion both are connected.Its weak point is only to rely on to change the flow of flue gas mode to carry out the dry type smoke medicining dust-removing effect undesirable.
The purpose of this utility model is to provide a kind of boiler smoke damping device that has water spraying mechanism.
The purpose of this utility model can realize by following measure: a kind of boiler smoke damping device, it is characterized in that: on the tapered wall of Venturi tube collapsible tube, be provided with a circle hole for water spraying of forming by uniform through hole, on the perisporium of trunnion, also be provided with a circle hole for water spraying of forming by uniform through hole in addition, be provided with cylindrical outer casing with its containing in the outside of Venturi tube, its up and down two ends respectively with the Venturi tube collapsible tube, anemostat connects, the through hole that the water inlet pipe that links to each other with water pump passes on the shell enters in the interlayer, is provided with the delivery pipe of the band valve that is connected with interlayer at outer casing underpart.
The utility model mainly includes: Venturi tube, shell and water inlet pipe and water outlet pipe.Wherein Venturi tube and existing Venturi tube are basic identical, different is to be provided with a circle hole for water spraying of being made up of some uniform through holes on the tapered wall of Venturi tube collapsible tube, on the perisporium of trunnion, also be provided with a circle hole for water spraying of forming by some uniform through holes in addition, be provided with cylindrical outer casing with its containing in the outside of Venturi tube, it is connected with anemostat with the Venturi tube collapsible tube respectively at two ends up and down, makes the interlayer of folded part for sealing between the two.The through hole that the water inlet pipe that links to each other with water pump passes on the shell enters in the above-mentioned interlayer, and this water inlet pipe can be constantly injects the water purification with certain pressure in interlayer, alkaline water that preferably can desulfurization.Be provided with the delivery pipe of the band valve that is communicated with it at outer casing underpart, in order to the maintenance usefulness that discharges water.
The flue gas of discharging when boiler, not only will be subjected to the effect of Venturi tube structure itself, but also will be subjected to being washed by the water curtain of collapsible tube and the ejection of trunnion hole for water spraying through out-of-date from above-mentioned Venturi tube.If this venturi plumber does the time when long slightly, high-temperature flue gas can be with the heating of the water in the interlayer so that boiling, water vapour is from the hole for water spraying ejection of Venturi tube upper body, these water vapours that contain spray water can further capture the flue dust in the flue gas again.
The utility model has following advantage compared to existing technology: the flue gas that boiler is discharged, not only is convenient to capture behind washing and the steam humidification through Venturi tube, make efficiency of dust collection increase by 10%, and the alkaline matter in the water also helps to slough the sulphur in the flue gas.
Drawing is described as follows:
Fig. 1 is that the utility model master looks generalized section.
The utility model is described in further detail to utilize the example shown in the accompanying drawing.Master at boiler smoke damping device shown in Figure 1 looks in the generalized section, and Venturi tube 1 anemostat is a long frustum shaped pipe, and collapsible tube 2 is a cutting back conical pipe, and both are small-bore identical, by trunnion 3 both is linked to each other.On the tapered wall of Venturi tube collapsible tube, be provided with by circle hole for water sprayings 4 of forming as if 12 uniform through holes, on the perisporium of trunnion, also be provided with the circle hole for water spraying 5 that 6 uniform through holes are formed in addition.Be provided with the cylindrical outer casing 6 with its containing in the outside of Venturi tube, it is connected with convergent divergent channel with the Venturi tube collapsible tube respectively at two ends up and down, makes the interlayer of folded part for sealing between the two.The water inlet pipe 7 that links to each other with water pump passes that through hole enters in the above-mentioned interlayer on the shell, is provided with the delivery pipe 8 of the band valve that is communicated with interlayer at outer casing underpart.
