Description

Flue gas processing equipment of boiler

Technical field

The utility model relates to a kind of flue gas processing device, especially flue gas processing equipment of boiler.

Background technology

The flue gas that the boiler for domestic using coal to do fuel is discharged mainly comprises flue dust and sulfur dioxide.In the market comparatively large to flue gas processing equipment of boiler floor space, price is more expensive, use cost is high, is not suitable for the fume treatment of boiler for domestic.

Utility model content

For solving the problem, the utility model provides a kind of investment little, and take up an area little, that efficiency is high boiler for domestic flue gas processing device, concrete technical scheme is:

Flue gas processing equipment of boiler, comprises treating column, cyclic water tank, water atomization shower nozzle, spoiler, lime slurry shower nozzle and gas-liquid net; Described treating column top is provided with blast pipe, and bottom is provided with lower margin, and treating column is divided into two-layer up and down, is respectively Shang Ta and Xia Ta, is communicated with between Shang Ta and lower tower by middle fume pipe; Water stopping cap is provided with above described middle fume pipe; The lower tower bottom of described treating column has water, and exhaust inlet pipe is fixed on below water level; Described cyclic water tank is connected by pipeline with the lower tower bottom for the treatment of column, is provided with coarse filtration net and thin screen pack in cyclic water tank; Described cyclic water tank is connected by water pump with water atomization shower nozzle; Described water atomization shower nozzle is fixed on the top under treating column in tower; Described spoiler is fixed on below water atomization shower nozzle; On described treating column, the bottom of tower is provided with lime slurry recovery tube; Described lime slurry shower nozzle is fixed on the top of tower on treating column; Described gas-liquid net is fixed on the below of lime slurry shower nozzle.

Described gas-liquid net is no less than two-layer.

Flue gas enters into the water of tower bottom under treating column, reduces the temperature of flue gas, decreases flue dust simultaneously.At the flow direction of flue gas, spoiler is installed, makes flue gas curvilinear motion, increase flow of flue gas distance and time, too increase the contact surface of flue gas and water simultaneously.Under treating column, the water atomization shower nozzle ejection water smoke of top of tower, further increases dust removing effects.

Flue gas enters tower on treating column by middle fume pipe, lime slurry sprinkler goes out fine and closely woven uniform milk of lime droplet, milk of lime droplet mixes with flue gas and contacts, and generate calcium sulfite with the sulfur dioxide generation chemical reaction in flue gas, the sulfur dioxide in flue gas is removed.Flue gas has to pass through gas-liquid net, and gas-liquid net adds the contact area of flue gas and lime slurry, accelerates chemical time, also can play the effect of dedusting simultaneously.

The flue gas processing equipment of boiler that the utility model provides, energy-efficient, invest little, take up an area little, install simple, operating cost is low, power saving, water-saving, and dedusting, desulfuration efficiency are high.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.
