Abstract
The utility model discloses an impact liquid column flue gas cleaner. The utility model is provided with a tower body, wherein the inner of the tower body is provided with a dehumidifying device, a liquid column hole plate, a liquid spraying pipe network and a flue gas inlet in sequence. The upper end of the tower body is connected with a wind introducing machine, and the lower end is connected with a circulating water pool; the upper part of a circulating water column is provided with an inlet for lime carbonate serous fluid and an inlet for water, and the bottom is provided with a drain, an air inlet and a circulating water pump. A plaster serous fluid pump is connected with the drain, the plaster serous fluid pump is connected with a plaster sedimentary pool device, and the circulating water pump is connected with the liquid spraying pipe network through a valve. The utility model has low initial investment cost which is only 10-20% of the foreign similar wetting desulphurization device, and the utility model is not easy to block with reliable system operation.
Description
The utility model relates to burner, relates in particular to impacting liquid column fume purifier.
Develop the SO of China rapidly along with industrial
2Discharging has caused many areas the serious acid rain phenomenon to occur.Solve atmosphere polluting problem, protect the ecological environment of the whole earth, become instant problem.
At present, the stricter SO of oneself formulation of China
2Pollution control regulations, and take to limit the measures such as exploitation, development flue gas desulfurization technique and reinforcement blowdown guiding principle collection system in high-sulfur colliery.At present, the SO of more than 40 ten thousand annual dischargings of China's station boiler total capacity 182.9WG and Industrial Boiler
2=Amount accounts for about 70% of total release, is SO
2Pollute the control emphasis.And very expensive from the flue gas desulfurization device price of external introduction, operating cost is also very high; The domestic simple wet process of FGD dust arrester of oneself developing also exists problems such as desulfuration efficiency is low, equipment corrosion stops up seriously, flue gas with water, has influenced in China greatly and has further applied.
The purpose of this utility model provides that a kind of cost of investment is low, operating cost is low, is not easy to stop up the impacting liquid column fume purifier that system is reliable.
The utility model is taked following measures in order to achieve the above object:
Impacting liquid column fume purifier has tower body, be provided with dehydrating unit, fluid column orifice plate, hydrojet pipe network, smoke inlet in the tower body successively, the tower body upper end is provided with the air-introduced machine interface, following termination circulating water pool, circulation water column top is provided with lime stone slurry inlet and water inlet, the bottom is provided with sewage draining exit, air intake, water circulating pump, and water circulating pump joins through valve and hydrojet pipe network.
The utility model has proposed a kind of simple in structure, column for smoke purification that desulfuration efficiency is high on the basis that fully absorbs domestic and international advanced flue gas desulfurization technique.Its advantage is:
1) initial cost cost minuent only is 10～20% of an external similar wet desulphurization device;
2) owing to adopt good gas-liquid contact form, the desulfuration efficiency height draws an efficient routine point through a large amount of experimental studies: at spray flux 30m
3Wind speed 2.6m/s (liquid-gas ratio 11.51/m in/h, the tower
3), during loop slurry pH value 5.7, desulfuration efficiency can reach 93.8%, and the interior absorber portion resistance of tower this moment is not very big, has only 70mmH
2O; Thereby the actual operating mode scope is: liquid-gas ratio 1O～151/m
3, wind speed 2～3m/s in the tower, loop slurry pH value 4～6, desulfuration efficiency 79%, absorber portion resistance 70mmH
2O.
3) operating cost is low, and desulfurizing agent adopts cheap agstone, and can generate by-produced gypsum; 4) be not easy to stop up, system is reliable, impacts fluid column formula desulphurization reaction owing to adopt, and has significantly reduced the obstruction of system;
5) flue gas with water is few, has reduced the harmful effect of wet flue gas to chimney.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing is to have system schematic of the present utility model.
Impacting liquid column fume purifier has tower body 1, be provided with dehydrating unit 2, fluid column orifice plate 3, hydrojet pipe network 4, smoke inlet 5 in the tower body successively, termination air-introduced machine 15 on the tower body, following termination circulating water pool 6, circulation water column top is provided with lime stone slurry inlet 7 and water inlet 8, and the bottom is provided with sewage draining exit 9, air intake 10, water circulating pump 12, connects calcium plaster liquid pump 11 at sewage draining exit, calcium plaster liquid pump and gypsum settling tank device 14 join, and water circulating pump joins through valve 13 and hydrojet pipe network 4.
Said gypsum settling tank device 14 is by calcium plaster liquid pump 11 1 termination hydrocyclones 16, the logical settling tank II21 in hydrocyclone upper end, the lower end is to filtering belt 17 front ends, filter the belt rear end to wet gypsum storehouse 18, filter belt dressing front end delivery port and meet settling tank I19, the rear end delivery port meets settling tank II, and settling tank I bottom is provided with discharge of wastewater mouth 20, also have a delivery port to meet settling tank II on one side, another edge joint circulating water pool 6 of settling tank II on the limit.
Above-mentioned fluid column orifice plate percent opening 40～70%, the fluid column orifice plate is 1.5～3m to dehumidifying panel assembly distance, the fluid column orifice plate is 4.5～8m to hydrojet pipe network distance.
The flue gas that is generated by burner combustion mixes with the sulfur dioxide that air and sulfur dioxide storage tank are sent into and forms the certain sulfur dioxide of uniform temperature.Flue gas is after treatment removed droplet by removing wet plate, through smoke stack emission to atmosphere.
In the gas cleaning tower body, the hydrojet pipe network is equipped with the nozzle of the special processing of many groups.The flue gas shower nozzle of flowing through sprays at a high speed, is uniform loose shape fluid column, contacts with the flue gas following current; Powerful impact had the baffle plate of perforate and sharply changes the flow direction after fluid column rose to certain altitude, and inspired a large amount of foam sprays; Drop alternately contacts with flue gas adverse current, following current owing in the process that the self gravitation effect is fallen, also can form secondary even repeatedly impact to baffle plate under the rolling action of flue gas, and flue gas is subjected to the shower effect of spray drop, and desulfurized effect is very good.
