Abstract
The utility model discloses a device for treating flue gas with a semi-dry method. The device comprises an absorber, wherein a sprayer is arranged in the absorber which is connected with a digestion tank through a digestive fluid pipe; a first water pump is arranged on the digestive fluid pipe; a CaO bin is arranged on the digestion tank; the lower end of the absorber is connected with a circulating fluid tank which is connected with the absorber through a circulating fluid pipe; a second water pump is arranged on the circulating fluid pipe; a flue gas feed pipe is further arranged on the absorber connected with a chimney through a flue gas discharge pipe; a dust remover is arranged on the flue gas discharge pipe; and ash bins are arranged below the dust remover. According to the device, a mixture containing water is reused, so that the wastewater quantity and the water consumption are greatly reduced; and at the same time, the semi-dry method is used for treating the flue gas, defects existing during treatment with the wet method and the dry method are overcome, and the treatment effect of flue gas is improved.
Description
Technical field
The utility model relates to a kind of semidry method flue gas processing device.
Background technology
Flue gas treating process divides three classes at present: wet method, dry method and semidry method; Wet processing maturation, efficiency are high, be widely used, but have that cost is high, floor space and water consumption greatly, easily produce secondary pollution, ammonia leaks and the problem such as equipment corrosion; The advantage of dry method is that technical process is simple, without sewage, dirty acid treatment problem, energy consumption is low, and after particularly purifying, flue-gas temperature is higher, is conducive to chimney exhaust diffusion, can not produce " white cigarette " phenomenon, flue gas after purification does not need post bake, and corrosivity is little, but that its shortcoming is desulfuration efficiency is lower, equipment is huge, investment is large, floor space is large, and operating technology requires high; Because wet method and dry method have certain shortcoming in smoke gas treatment, in order to overcome these shortcomings, and accomplish getting both of benefit and environmental protection, it is instant studying a set of semidry method flue gas processing device.
Summary of the invention
(1) technical problem that will solve
For addressing the above problem, the utility model proposes a kind of low cost, low water consumption, floor space little, can avoid ammonia to leak and equipment corrosion, and there is the semidry method flue gas processing device of obvious desulfurized effect.
(2) technical scheme
Semidry method flue gas processing device of the present utility model, comprises absorber; Described absorber inside is provided with fog-spray nozzle; Described absorber is connected with digester by digestive juice pipe; On described digestive juice pipe, be provided with the first water pump; On described digester, be provided with CaO feed bin; Described absorber lower end is connected with circulation flow container; Described circulation flow container is also connected with absorber by circulation fluid pipe; On described circulation fluid pipe, be provided with the second water pump; On described absorber, be also provided with flue gas and send into pipe; Described absorber is connected with chimney by smoke discharge pipe; On described smoke discharge pipe, be provided with deduster; Described deduster below is provided with ash silo.
Further, on described fog-spray nozzle, be provided with aperture.
Further, described aperture is provided with multiple.
Further, described the first water pump and the second water pump are emulsion pump.
Further, described deduster is sack cleaner.
Further, described ash silo is provided with one or more.
(3) beneficial effect
Compared with prior art, it has following beneficial effect to the utility model: a kind of low cost of the present utility model, low water consumption, floor space are little, can avoid ammonia to leak and equipment corrosion, and has the semidry method flue gas processing device of obvious desulfurized effect; The utility model, in the time of work, is delivered to absorber by the first water pump by lime white, and carries out chemical reaction with the flue gas that enters absorber inside; Reacted aqueous mixture enters circulation fluid pipe, and is delivered to absorber by the second water pump, carries out secondary utilization; Reacted flue gas enters deduster; Deduster is to the particulate pollutant in flue gas, and neutralization reactant collects, and is stored in ash silo, and clean flue gas will be by smoke stack emission to atmosphere; The utility model carries out secondary utilization to aqueous mixture, greatly reduces wastewater flow rate and water consumption; The utility model adopts semidry method to administer flue gas simultaneously, has overcome the shortcoming that wet method and dry treatment exist, and has reduced to greatest extent equipment corrosion and energy consumption, has avoided the secondary pollution of ammonia leakage and flue gas simultaneously, has improved the regulation effect of flue gas.
