Description
Technical field
The utility model relates to a kind of waste gas treatment equipment field, particularly relates to a kind of wet-type desulfuration oxidation device.
Background technology
Along with industrial expansion, the discharge of China SO2 serious acid rain phenomenon that caused many areas to occur, the annual caused thus is lost in more than 24,000,000,000 yuan.For solving present atmosphere polluting problem, China has formulated strict SO2 pollution control regulations, to the city requirement flue gas desulfurization qualified discharge in " dicontrolled area ".
The Energy Mix of China is based on coal, and its consumption figure accounts for about 70% of primary energy aggregate consumption, and coal directly burns and discharges a large amount of SO2 and dust causes air environmental pollution.Research and development flue gas desulfurization and dedusting technology is fallen over each other in current countries in the world, China is also generally applying, conventional the having of boiler flue gas desulfurization process: dry method furnace sorbent injection desulfurization, semidry-method recirculating fluidized bed flue gas desulfurization, wet method lime stone one gypsum, magnesium oxide method, sodium alkali, Dual alkali, ammonia process, seawater method etc.Current wet process of FGD is considered to the most ripe, the most effective approach of control SO2.
Wet-type desulfurize and dust removing technology can remove the pernicious gas such as dust and sulfur dioxide in flue gas, is widely used in the desulfurization and dedusting of coal-fired flue-gas.Traditional wet type desulfurizing dust collector utilizes wet type to collide or flue dust to be thrown on wall and to be washed by the moisture film of deduster inwall by centrifugal force, reaches the object of desulfurization and dedusting.This device once played a positive role to the desulfurization and dedusting of coal-burning boiler, kiln gas.But the weakness that along with going deep into of environmental protection, its efficiency of dust collection is low, desulfurized effect is poor appears gradually, the coal-fired flue-gas discharge standard of current increasingly stringent can not be met.
Summary of the invention
In order to solve the problem that existing wet type desulfurizing dust collector efficiency of dust collection is low, desulfurized effect is poor; The utility model provides a kind of wet-type desulfuration oxidation device, this wet-type desulfuration oxidation device adopts three pull-up sulphur, dust removal installation, can not only remove the pernicious gas such as dust and sulfur dioxide in flue gas effectively up hill and dale, and efficiency of dust collection is high, economical operation, management and maintenance is convenient.
The utility model solves the technical scheme that its technical problem adopts: a kind of wet-type desulfuration oxidation device, comprises air blast, scrubbing tower, sewage draining exit, circulating pump, water pipe, giant, demister, isocon, atomizer, moisture trap, exhaust outlet, tower cover, aerator; Described air blast is connected by tracheae and scrubbing tower lower end; Scrubbing tower upper end is communicated with tower cover; Be provided with sewage draining exit bottom tower cover, top is provided with exhaust outlet; Be laid with double-deck giant in the middle part of tower cover, giant is communicated with tower cover lower end by water pipe, is provided with circulating pump between water pipe; Isocon is divided into three layers, is arranged in giant windward; Be provided with demister between two-layer isocon, above isocon, moisture trap be installed.
Described tracheae and scrubbing tower junction are provided with aerator; Exhaust gas diffusion is evenly fully reacted with solution, thus removal foul gas.
Described isocon is provided with atomizer; Can by cleaning solution atomization ejection, and even suspension is in air, when waste gas is through out-of-date, utilizes grit and the contact-impact of water droplet and reunites between phase inter coagulation or grit, making its weight greatly increase and land.
Giant between described adjacent two layers is interlaced arrangement, and the distance of two interlayers is 0.5 ~ 1m; Thus the water smoke making adjacent giant spray overlaps imbrication mutually, does not interspace, the drop of ejection is made to cover the whole section of tower cover completely.
The utility model, a kind of wet-type desulfuration oxidation device, after sealing collection, first sucks scrubbing tower by air blast by the foul smell of centralized collection and washs the foul smell of each smelly source structures generation, after removing the gas in foul gas, then pass in tower cover and purify.Cleaning solution is atomized into fine drop by atomizer and sprays equably, and dusty gas is entered by tower cover bottom, bottom-up flowing, both counter current contacting, utilize grit to reunite between phase inter coagulation or grit with the contact-impact of water droplet, its weight is increased greatly, depends on Action of Gravity Field to settle down.The dust be captured makes gravitational settling, and the height bottom being formed contains solid concentrated phase liquid and regularly discharge is for further processing.Part clarified solution can be recycled, and enters tower cover carry out spray washing together with a small amount of supplementary clear liquid through circulating pump from tower top giant, thus decreases the consumption of liquid and the treating capacity of secondary sewage.Purge gas after spray washing, after the fine drop by demister removing gas entrained with, then is discharged in air by exhaust outlet after being separated by moisture trap.
A kind of wet-type desulfuration oxidation device of the utility model, its beneficial effect is:
1) this wet-type desulfuration oxidation device water consumption power consumption is low, and gas treatment amount is large, is suitable for the purified treatment of extensive flue gas;
2) this wet-type desulfuration oxidation device structure is simple, and volume is little, constructability, and process structures are few;
3) this wet-type desulfuration oxidation device operational administrative is simple, and maintenance cost is extremely low.
