The utility model by adopting the above technical scheme, the beneficial effect is that：The modified coal-fired steam boiler eliminates smoke de-
Sulphur dust-extraction unit, energy-saving and environmental protection, desulfurization and dedusting effect are good.It is energy saving in order to avoid wasting water, it is additionally arranged filter, water
The soluble gas ingredient in flue gas by recycling for water, gas-liquid interaction dedusting, and is adsorbed, prominent desulfurization in pond, clarifier
Effect；In order to improve desulfurization and dedusting effect, smoke barrier is provided in sprayed tank, and logical provided with strip on smoke barrier
Hole, ash-laden gas enter after sprayed tank due to being provided with smoke barrier, change flue gas flow direction, flue gas is made to impact the water surface, portion downwards
Divide thick grit to be captured by water, as the residence time increases ash-laden gas in sprayed tank, keeps ash-laden gas wet in sprayed tank
Degree increases, and by gravity, falls into the sprayed tank lower part water surface, the flue gas after dedusting then passes through the strip on smoke barrier
Through-hole is delivered to smokejack, is discharged hence into chimney.
Detailed description of the invention
Fig. 1 is the flow diagram of the utility model.
Fig. 2 is the structural schematic diagram of the sprayed tank of the utility model.
In figure：Flue 10, cyclone dust collectors 20, water diversion disk 201, spray thrower 202, sprayed tank 30, smoke barrier 301,
Water fender 302, solid-liquid separator 303, chimney 40, filter 50, pond 60, small pump 70, clarifier 80.
Specific embodiment
Please refer to Fig. 1 to Fig. 2, the utility model embodiment provides a kind of modified coal-fired steam boiler smoke-eliminating desulfurizing and removes
Dirt device, including flue 10, cyclone dust collectors 20, sprayed tank 30, chimney 40, filter 50, clarifier 80, the flue gas
Pipeline 10 is connected to 20 main body of cyclone dust collectors in tangential direction, and the cyclone dust collectors 20 are provided with closed top, and water supplying pipe connects
It passes in the closed top of cyclone dust collectors 20 and is connected with water diversion disk 201, so that the water in water supplying pipe uniformly disperses, whirlwind
Deduster 20 bores the right side that bottom is communicated to the top of 30 inner cavity of sprayed tank, and the cone bottom of cyclone dust collectors 20 is provided with spray thrower 202,
So that wet flue gas and water uniformly disperses, increase the contact area of flue gas and water, the inner cavity of the sprayed tank 30 is provided with

Water in water supplying pipe uniformly disperses, and cyclone dust collectors cone bottom is communicated to the right side at the top of sprayed tank inner cavity, cyclone dust collectors
Cone bottom is provided with spray thrower, so that wet flue gas and water uniformly disperses, increases the contact area of flue gas and water, the spray
The inner cavity of tank be provided with the top of the inner cavity of sprayed tank smoke barrier connected vertically, and smoke barrier setting is in spray thrower side,
For changing flue gas flow direction, flue gas is made to flow downward, is uniformly distributed on the smoke barrier in the sprayed tank there are three strip
Through-hole is filled with temporary water in the sprayed tank, sprayed tank is provided with the liquid level control of temporary water for the flue gas circulation after dedusting
Device processed, fluid level controller are connect with the autocontrol valve on sprayed tank bottom discharge pipe, and the liquid level in sprayed tank is higher than described
Smoke barrier, lower than the through-hole of the strip of the bottom on the smoke barrier, the cavity of the sprayed tank in the left side of the smoke barrier
On be communicated with smoke exhaust pipe, smoke exhaust pipe stretches out sprayed tank and is simultaneously connected to extraneous funnel body, the import of the filter with it is described
The bottom of sprayed tank is connected to, and the outlet ends of the filter are connected to pond, are provided with small pump on the pond, is used for water
Water in pond is evacuated to water supplying pipe, and the import of the clarifier is connected to small pump, it is purified after water rotation is sent to by water supplying pipe
Circulation waterway is formed in wind deduster.
