Described one heavy pond links to each other with two ponds of outside are heavy.
Be provided with the baffle device for water that four layers of angle bar form in the described dehydrating tower.
Beneficial effect of the present invention has:
Native system integrates spray, whirlwind, the dust-removal and desulfurizing process such as impacts, washes away, efficiency of dust collection＞98%, desulfuration efficiency＞90%, and not high to the dust contained flue gas concentration requirement that enters devulcanizer, this desulphurization system has good dust removing effects, is that other desulphurization system is incomparable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As shown in Figure 1, the exhanst gas outlet of boiler 1 of the present invention connects the air inlet of deduster 2, and the gas outlet of deduster 2 connects the air inlet of air-introduced machine 3, and deduster 2 is that sack cleaner or other type deduster all can.Air-introduced machine 3 air outlets connect the upper end of spray chamber 4, and the lower end of spray chamber 4 is installed on the desulfurizing tower 5.Desulfurizing tower 5 lower ends are installed on the desulfurizing tower basis tube 6, desulfurizing tower basis tube 6 sidewalls communicate with dehydrating tower basis tube 8 by connecting flue 7, on the dehydrating tower basis tube 8 dehydrating tower 9 is installed, the outlet of dehydrating tower 9 upper ends connects chimney 10, be placed with doctor solution in described desulfurizing tower basis tube 6 and the dehydrating tower basis tube 8, its liquid level can be regulated according to the resistance and the regulation effect of flue gas.The bottom of desulfurizing tower basis tube 6 and dehydrating tower basis tube 8 is equipped with swash plate 11,
The lower ending opening of swash plate 11 is connected with a heavy pond 13 between desulfurizing tower basis tube 6 and dehydrating tower basis tube 8, and 13 in a heavy pond links to each other with two ponds heavy 14 of outside.Handling the mud (dust in the flue gas falls into doctor solution and forms mud) collected through desulfurizing tower basis tube 6 and dehydrating tower basis tube 8 devices is effluxed by sludge pump to Ji Nikou along swash plate 11 landings.
The upper portion side wall of desulfurizing tower main body 5 of the present invention is provided with secondary spraying mouth 12, and is provided with the baffle device for water 15 that four layers of angle bar form in dehydrating tower 9.Desulfurizing tower basis tube 6 among the present invention and dehydrating tower basis tube 8 can be that concrete is made.
The course of work of the present invention is as follows:
The sulfurous gas that comes out from boiler 1 enters air-introduced machine 3 after deduster 2 dedustings, enter this desulfurizer through air-introduced machine 3.The first step enters spray chamber 4, and the doctor solution of spray is fully mixed in flue gas and the spray chamber 4 enters desulfurizing tower 5 after contacting.Mixed flue gas from top to bottom in desulfurizing tower 5 again the connection flue 7 from desulfurizing tower basis tube 6 sidewalls arrive dehydrating towers 9, flue gas drains into chimney 10 after dehydrating tower 9 dehydrations, enter atmosphere from chimney 10.
The present invention is because spray chamber 4 high-order layouts, flue gas with motion from top to bottom after doctor solution fully mixes, enter in the process that desulfurizing tower moves downward, because the dilatation flue gas flow rate slows down to some extent, help dust, impurity, water smoke and collide mutually, form bigger material, when it arrives desulfurizing tower 5 bottom comers places with flue gas, because gravity, action of centrifugal force, most of dust, impurity and drop directly fall in the desulfurizing tower basis tube 6 of desulfurizing tower 5 lower ends, finish preliminary desulfurization and dedusting process.
Because desulfurizing tower 5 and dehydrating tower 9 lower ends are open design, and fuse with the basis tube of lower end, the basis tube communicates with circulatory pool, the liquid level of doctor solution is adjustable in the tube of basis, when liquid level raise, flue 7 sectional areas that are connected that connect desulfurizing tower basis tube 6 and dehydrating tower basis tube 8 diminished, and the contact area of flue gas and liquid level increases, flue gas flow rate increases, and part dust and drop fall into doctor solution again and finish desulfurization and dedusting process for the second time when impact liquid level.
Flue gas enters dehydrating tower 9 bottoms after connecting flue 7, and then turn to and move upward, because during by connection flue 7, flue gas flow rate increases, promptly increase the centrifugal force of dust and drop in the flue gas simultaneously, when flue gas moves upward,, finish desulfurization and dedusting process for the third time because centrifugal action dust in flue gas and drop fall into dehydrating tower 9 bottoms again.Last flue gas enters atmosphere from chimney 10 after dehydrating tower 9 dehydrations, finish whole process.
Baffle device for water 15 in the dehydrating tower 9 of the present invention has four layers of angle bar to divide two groups of arrangements, and angle bar one end is welded in cylindrical shell, and the other end surpluss 30 to updip
ODock with the angle bar of another identical set at the angle, last layer angle bar and following one deck are apart from 150mm, stagger in the position, two layers is one group totally two groups, collide with the last layer watertight layer again through rolling in the uphill process that looses in the wet flue gas uphill process with after following one deck collision, captured by the dash angle bar after fine droplet constantly condenses through repeatedly colliding, along angle bar to the barrel landing.It is big that baffle device for water 15 in the dehydrating tower 9 have angle bar layer intensity, and anti-filling rinsed, knocked, and be convenient to cleaning and safeguard, and characteristics such as high temperature resistant.
The undeclared part of other that the present invention relates to is same as the prior art.
