Description

The high-efficient washing wet dust collector
Technical field: the utility model relates to a kind of washing wet dust collector.Be arranged between boiler flue outlet and the chimney, in order to remove the flue dust that boiler fired coal produces.Belong to boiler smoke dedusting technology field.
Background technology: coal is (air blast and air-introduced machine shut down) when boiler shutdown, owing to anoxic, cause imperfect combustion, and produce a spot of black smoke dirt in the stove hall.Because the deduster of existing use causes boiler flue, chimney, deduster three to be communicated with, when boiler shutdown, unburnt flue gas will gather stove hall, flue, deduster and chimney inside in the stove hall, make the chimney a small amount of black smoke (chimney has from gravitation) of emerging, during to boiler blow-on (air blast and air-introduced machine turn round again), air-introduced machine will enter atmosphere to the flue dust that accumulates in stove hall, deduster, chimney inside, and efficiency of dust collection is low.
Summary of the invention:
The purpose of this utility model is to provide a kind of can make boiler flue, chimney and the deduster three is disconnected, dust removing effects is high deduster.
Technology contents of the present utility model is: a kind of high-efficient washing wet dust collector, comprise casing, flue and dividing plate, the crack plate is with left and right dirt pocket and the dewatering station of being separated into of cabinets cavity, dirt pocket top offers gas approach, flue inserts gas approach, the dirt pocket bottom is provided with the pond, and the pond is outside equipped with blowdown overflow water seal, and insert in the pond flue lower end; Dewatering station's one side is provided with exhanst gas outlet.Boiler is when blowing out, because the flue import of deduster inside is to insert in the pond, the gas approach and the exhanst gas outlet of deduster are not communicated with, make between boiler flue and the chimney and when blowing out, cut off by deduster, chimney has not just had self-suction, and the flue dust that imperfect combustion is produced reduces, and the passage of flue dust is blocked by the pond face, the a small amount of flue dust that gathers deduster is blocked by the pond, can only accumulate in the washing chamber of stove hall, flue and deduster.The dewatering station of deduster and chimney inside just do not have unburnt flue dust like this, just do not have black smoke to discharge when air-introduced machine starts.When boiler is reset, the abundant flue gas that produced of burning and originally accumulated in flue dust in the stove hall and mix and enter deduster in the stove hall, through the washing water-bath purify dewater after, enter atmosphere by air-introduced machine.
Because flue dust is to be difficult for hydrophilic black smoke, the flue dust water bath dust-removing effect that directly falls into the water is also not ideal, for this reason, the utility model also can adopt Venturi tube with flue, Venturi tube comprise top collapsible tube, middle part trunnion, bottom increaser and be arranged on the top collapsible tube and the bottom increaser in nozzle.Because the import of flue and outlet all are provided with nozzle, make the progressively moistening mixing of flue dust and water smoke and fall into the pond, and reach the purpose of further smoke abatement and dust control.
Because the effect of air-introduced machine suction and external pressure (existence of blowdown overflow water seal), it is too high to cause indoor pond liquid level to rise, it is too dark that flue is inserted in the water, influence the room pressure loss, for this reason, the utility model also can be provided with the spilling water groove or/and adopt double pollution discharge overflow water seal (outlet of former water seal is inserted in the water again) near the dewatering station place in the dirt pocket bottom, sewage in the pond is in time overflowed through tank or water seal outflow deduster, and maintenance constant water level, make indoor crushing normal, the boiler normal operation.
Description of drawings:
Fig. 1 is an example structure schematic diagram of the present utility model
Fig. 2 is a flue structural representation of the present utility model
Fig. 3 is another example structure schematic diagram of the present utility model
The specific embodiment:
As Fig. 1, the utility model is a kind of high-efficient washing wet dust collector.Mainly form by casing 1, flue 3 and dividing plate 5.Dividing plate 5 is with left and right dirt pocket 4 and the dewatering station 6 of being separated into of casing 1 inner chamber, dirt pocket 4 tops offer gas approach 2, gas approach 2 plug-in mounting flues 3, and dirt pocket 4 bottoms are provided with pond 9, pond 9 is outside equipped with blowdown overflow water seal 10, and water seal 10 can be adopted double-deck water seal.Insert in the pond 9 flue 3 lower ends, and dirt pocket 4 bottoms are provided with spilling water groove 8 near the dewatering station place, with water level in the control room.Make the boiler normal operation.Dewatering station's 6 one sides are provided with exhanst gas outlet 7.
As Fig. 2, flue adopt Venturi tube, Venturi tube to comprise top collapsible tube 12, middle part trunnion 13, bottom increaser 14 and be separately positioned on the top collapsible tube and the bottom increaser in nozzle 11,15.
Washing water-bath dust-cleaning principle:
The dusty gas of uniform temperature, at first enter in Venturi tube top, the dirt pocket top collapsible tube (saturated chamber), at this atomized water spray, because thin atomized water spray reaches capacity flue gas or hypersaturated state, when saturated flue gas was passed through the trunnion at Venturi tube middle part, flow velocity is anxious to be increased, and static pressure is die-offed, this moment is as adiabatic expansion, make water droplet continue evaporation, when air-flow entered the increaser of Venturi tube, air velocity reduced, static pressure increases suddenly, steam begins condensation, and tiny grit becomes nucleus of condensation, and water vapor condensation is to grit, make its outside water membrane that forms, water droplet in the gas produces speed difference with the grit that is encased by moisture film owing to density is different, make its mutually between collision, become thicker condensate, establish nozzle in the Venturi tube exit, further wash grit.The drop flue gas that contains after the washing enters in the pond of bottom, washing chamber with certain gas speed, the outlet of Venturi tube is to insert in the pond, the dust-laden drop can only pour in the pond and can directly do not siphoned away by the gravitation of air-introduced machine, pass water layer through the water-bath purified gas, enter dewatering station, enter atmosphere by chimney after dewatering, mud is discharged from the bottom water seal.
As Fig. 3, be provided with one or more eddy flow plates 16 in the flue 3, constitute rotating stream tray scrubber.Eddy flow plate top is provided with nozzle 17, liquid is evenly divided on each blade of layout eddy flow plate, form thin liquid layer, when air-flow from top to bottom passes through blade, produce rotation and centrifugal motion, thin liquid layer is cut into tiny droplet, become helix to get rid of to tube wall, drop collides cohesion on tube wall, under assembling under the effect of gravity.In addition, the eddy flow plate almost all integrates dust-removal and desulfurizing when smoke treatment.
