A kind of gas-liquid turbulence type desulfurizing dust-collector of the embodiment of the present invention, comprises into cigarette tower 1, gas-liquid turbulence type desulfurization and dedusting king-tower 2 and smoke evacuation secondary tower 3; The lower end of entering cigarette tower 1 is connected with gas-liquid turbulence type desulfurization and dedusting king-tower 2 by exhaust gases passes 9, and the top of gas-liquid turbulence type desulfurization and dedusting king-tower 2 is connected with smoke evacuation secondary tower 3 by exhaust gases passes 9, and the lower end of smoke evacuation secondary tower 3 arranges the exhanst gas outlet being connected with air-introduced machine; The equal air chamber 12 of smoke distribution, gas-liquid turbulator 7, feed liquid pipeline 6 and first order dehydrating demisting device 5 are set respectively in gas-liquid turbulence type desulfurization and dedusting king-tower 3 from bottom to up; At the bottom of entering the tower of cigarette tower 1 and gas-liquid turbulence type desulfurization and dedusting king-tower 2, outfall 10 is all set.
As a prioritization scheme of the embodiment of the present invention, enter cigarette tower 1 for decreasing temperature and increasing humidity prewashing tower, what the top of entering cigarette tower 1 arranged pending flue gas enters mouth 4, enters the humidifier 8 that is provided for cooling, wetting flue gas in cigarette tower 1.
As a prioritization scheme of the embodiment of the present invention, in smoke evacuation secondary tower 3, in the top of exhanst gas outlet, be provided with second level dehydrating demisting device 12.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
As shown in Figure 1, this gas-liquid turbulence type desulfurizing dust-collector, comprises into cigarette tower 1, gas-liquid turbulence type desulfurization and dedusting king-tower 2 and smoke evacuation secondary tower 3; The lower end of entering cigarette tower 1 is connected with gas-liquid turbulence type desulfurization and dedusting king-tower 2 by exhaust gases passes 9, and the top of gas-liquid turbulence type desulfurization and dedusting king-tower 2 is connected with smoke evacuation secondary tower 3 by exhaust gases passes 9, and the lower end of smoke evacuation secondary tower 3 arranges the exhanst gas outlet being connected with air-introduced machine; The equal air chamber 12 of smoke distribution, gas-liquid turbulator 7, feed liquid pipeline 6 and first order dehydrating demisting device 5 are set respectively in gas-liquid turbulence type desulfurization and dedusting king-tower 3 from bottom to up; At the bottom of entering the tower of cigarette tower 1 and gas-liquid turbulence type desulfurization and dedusting king-tower 2, outfall 10 is all set.
Enter cigarette tower 1 for decreasing temperature and increasing humidity prewashing tower, what the top of entering cigarette tower 1 arranged pending flue gas enters mouth 4, enters the humidifier 8 that is provided for cooling, wetting flue gas in cigarette tower 1.
In smoke evacuation secondary tower 3, in the top of exhanst gas outlet, be provided with second level dehydrating demisting device 12, stop air-introduced machine band water, corrosion, smoke evacuation secondary tower 3 is connected with air-introduced machine power set with bottom, and the flue gas after flue gas desulfurization and dedusting purifies is by the external qualified discharge of chimney.
The gas-liquid turbulence type desulfurizing dust-collector of the embodiment of the present invention, first will be containing dust, the pending flue gas of sulfur dioxide pendingly enters mouth 4 and enters from what enter that cigarette tower 1 top arranges, entering humidifier 8 in cigarette tower 1 treats smoke treatment and lowers the temperature, wetting, mix, carry out pre-dedusting and cooling, the pernicious gas temperature such as sulfur dioxide are down to the temperature of the best neutralization reaction of sulfur dioxide, flue gas after cooling enters in gas-liquid turbulence type desulfurization and dedusting king-tower 2 by exhaust gases passes, flue gas enters in gas-liquid turbulence type desulfurization and dedusting king-tower and first passes through gas-liquid turbulator 7, gas-liquid turbulator place forms the turbulent air flow that rotation is risen, flue gas is with the state of High Rotation Speed and diffusion and the akaline liquid collision of upper end feed liquid pipeline 6 injections, air-flow high speed shear flows down liquid, liquid is sheared broken, gas-liquid is fully mixed, form strong turbulent mass transfer, the process of mass transfer is to make gas-liquid form certain altitude turbosphere, not only in chemical absorbing and fast, liquid film approaches neutral all the time, can make overall process keep high and stable desulfurization and dedusting speed.In turbulent flow process, turbosphere thickens gradually, and the turbulent flow liquid that the flue gas holder power of above walking and turbulent flow liquid are newly formed substitutes, and is being mingled with the impurity trapping and is discharging by the outfall 10 of desulfurization and dedusting king-tower bottom.Clean flue gas through desulfurization and dedusting further carries out dehydrating demisting processing by first order dehydrating demisting device 5, gas after processing enters in smoke evacuation secondary tower 3 by the exhaust gases passes on gas-liquid turbulence type desulfurization and dedusting king-tower top, the further dehydrating demisting of second level dehydrating demisting device 12 in smoke evacuation secondary tower 3 is processed, finally via air-introduced machine, smoke stack emission is aerial, discharges aerial flue gas and reaches discharge standard.
The gas-liquid turbulence type desulfurizing dust-collector scope of application of the present invention is wide, can be used in the tail gas producing in the industry production processes such as chemical industry, medical treatment, oil, the absorption of waste gas and purified treatment.Gas-liquid turbulence type desulfurizing dust-collector of the present invention can make dust and the SO in flue gas
2deng pernicious gas, fully contact, mix with akaline liquid, finally reach the object of purification, desulfurization dust-removing efficiency is high, efficiency of dust collection>=99.3%, desulfuration efficiency:>=97%.Gas-liquid turbulence type desulfurizing dust-collector of the present invention is because the liquid-gas ratio in tower is little, and water supply lift is low, and dust-removal and desulfurizing efficiency reaches peer-level, and water supply consumption is general packed tower, spray column 25% to 16% or lower, reduce system energy consumption more than 20%.Water consumption is 25% to 16% of external packed tower.Because this gas-liquid turbulence type desulfurizing dust-collector desulfuration efficiency is high, do not need to take too large space, so that the area of section of reaction tower and be highly all less than other technologies, generally than little 10% left and right of other tower bodies, total floor space also reduces greatly.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
