Abstract
The invention provides a desulphurization device used for preventing environment pollution for the first time. The desulphurization device comprises a gas inlet pipe (2), a cooling pipe (1), and a desulfurizing tower (8); the gas inlet pipe (2) is sleeved by the cooling pipe (1); water flow direction of the cooling pipe and exhaust gas flow direction of the gas inlet pipe (2) are opposite to each other; a outlet of the gas inlet pipe (2) is connected with the desulfurizing tower (8); a spray nozzle (5) is arranged in the desulfurizing tower (8); and the middle lower part of the desulfurizing tower (8) is provided with an exhaust pipe (6). The gas inlet pipe is coated by the cooling pipe completely so as to realize full heat exchange of exhaust gas with a cooling liquid in the cooling pipe, reduce the temperature of exhaust gas enters the desulfurizing tower, prolong retention time of exhaust gas in the desulfurizing tower, and improve desulphurization effects further.
Description
Technical field
The invention belongs to technical field of desulfurization, especially relates to a kind of antipollution desulphurization plant.
Background technology
The method of flue gas desulfurization has dry type flue gas desulfurizing technique, spraying dry type flue gas desulfurizing technique, flyash dry type flue gas desulfurizing technology, wet fuel gas desulfurizing technology etc., similar as the wet fuel gas desulfurizing technology flow process of countries in the world, form and mechanism, the slurries such as lime stone (CaCO3), quick lime (CaO) or sodium carbonate (Na2CO3) are mainly used to make washing agent, in reaction tower, flue gas is washed, thus the SO2 in removing flue gas.
Because the temperature of flue gas is very high, to forming higher pressure in desulfurizing tower, can reduce the time of staying of flue gas in desulfurizing tower on the other hand, desulfurized effect being deteriorated, easily causing the pollution of environment on the one hand.
Summary of the invention
In view of this, the invention is intended to propose a kind of antipollution desulphurization plant, to solve the problem causing desulfurized effect difference because flue gas is overheated.
For achieving the above object, the technical scheme of the invention is achieved in that
A kind of antipollution desulphurization plant, comprise air inlet pipe (2), cooling tube (1) and desulfurizing tower (8), described air inlet pipe (2) is set in described cooling tube (1), described cooling tube water (flow) direction is contrary with described air inlet pipe (2) flow of flue gas direction, described air inlet pipe (2) outlet is connected with described desulfurizing tower (8), be provided with shower nozzle (5) in described desulfurizing tower (8), described desulfurizing tower (8) middle and lower part is provided with blast pipe (6).
Further, described air inlet pipe (2) is by air inlet downward-sloping setting to gas outlet, and described air inlet pipe (2) roof is provided with some spray heads (3).
Further, described air inlet pipe (2) indentation.
Further, described desulfurizing tower (8) bottom is provided with reservoir (7).
Further, described desulfurizing tower (8) bottom is communicated with described reservoir (7), and described reservoir (4) is connected with described shower nozzle (5) by pipeline and compression pump.
Relative to prior art, the antipollution desulphurization plant described in the invention has following advantage:
In antipollution desulphurization plant described in the invention, cooling tube wraps air inlet pipe completely, the flue gas in pipe and cooling fluid is made fully to carry out heat exchange, thus the flue-gas temperature entering desulfurizing tower is reduced, increase the time of staying of flue gas in desulfurizing tower, and then improve desulfurized effect.
