Abstract

The utility model relates to an environmental protection device, in particular to an exhaust smoke desulfurization which is used for exhausting flue gas from a coal burning boiling. The utility model has a desulfurization tower under which a smoke inlet is arranged, and an exhausting chimney is connected with the top of the desulfurization tower directly. The inner chamber of the desulfurization tower is provided with multigrade smoke and gas processing segment, and a straying device is arranged on every smoke and gas processing segment; a gas distributing device is arranged between the two adjacent smoke and gas processing segments, also a defogger and a hydroextractor are arranged between the last smoke and gas processing segment. The utility model can exhaust the smoke and the gas and desulphurize the smoke and gas at the same time so that the smoke and the gas can be purified, the height of the chimney in the device are reduced and investment is saved.

Description

Desulfurizing and Exhaust Fume Integrated Apparatus

Technical field

The utility model belongs to environmental protection equipment, relates to a kind of Desulfurizing and Exhaust Fume Integrated Apparatus that is used for the fire coal boiler fume discharging.

Background technology

Existing coal-burning boiler all will be provided with a tall and big chimney, low then tens meters, the then hundreds of rice of height, its investment cost is huge, take bigger area and space, its purpose is just in order to lift the basket height for one of flue gas, be beneficial to the diffusion of flue gas, reduce of the direct pollution of pernicious gas such as SO2 in the flue gas ground.

Summary of the invention

Technical problem to be solved in the utility model is, a short Desulfurizing and Exhaust Fume Integrated Apparatus is provided, make it in the discharging flue gas, carry out desulfurization and handle flue gas, thereby can purify chimney in flue gas, the reduction equipment height, reduce investment outlay.

Desulfurizing and Exhaust Fume Integrated Apparatus of the present utility model includes a desulfurizing tower, in the desulfurizing tower bottom into mouth is arranged, and the top of desulfurizing tower directly is connected with a smoke evacuation chimney.The inner chamber of described desulfurizing tower is provided with the multistage flue gas processing section that is used for carrying out dedusting, desulfurization from the bottom to top, the top of each grade flue gas processing section is provided with a spray equipment that is used for spraying desulfurizing agent and cooling liquid, be provided with between each grade flue gas processing section and the back one-level flue gas processing section and be used for making the homodisperse gas distributor of the flue gas that passes through, demister and dehydrator in the end also are set, in order to remove the desulfurizing agent water smoke in the flue gas between the chimney at one-level flue gas processing section and top.

The utility model is owing to be provided with a desulfurizing tower below chimney, when flue gas is passed through can with the desulfurizing agent fast reaction in the tower, finish cooling, dedusting and sweetening process, and then by smoke stack emission, reduced the pollution of flue gas greatly, thereby the height of lower chimney can be set, saved investment.

Description of drawings

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

The specific embodiment

As shown in the figure, this Desulfurizing and Exhaust Fume Integrated Apparatus includes a desulfurizing tower 1, and into mouth 2 is arranged in the desulfurizing tower bottom, and the top of desulfurizing tower directly is connected with a smoke evacuation chimney 3.Multistage flue gas processing section 4 is set in the inner chamber of desulfurizing tower, and the top of each grade flue gas processing section is provided with a spray equipment 5, the desulfurizing agent that is used for spraying cooling liquid and reacts with flue gas; Through multistage gas distributor 6, flue gas is evenly disperseed in the flue gas uphill process, be beneficial to fully react with desulfurizing agent; Demister 7 and dehydrator 8 in the end also are set, in order to remove the desulfurizing agent water smoke in the flue gas between the chimney at one-level flue gas processing section and top.
