Description
[technical field]
The utility model relates to the conventional method of purifying exhaust air and is the specially designed equipment of these class methods or device technique field, specifically a kind of economic benefits and social benefits smoke eliminator.
[background technology]
In recent years, atmosphere pollution situation is further serious, serious haze phenomenon has been brought tremendous influence to people's lives in all parts of the country and work, also national economic development has been coverd with to shade, as the flue gas desulfurization technique of Air Pollutants emission control means, has born huge responsibility.Although, Technology for Domestic Flue Gas Desulfurization is through the development of more than ten years, many desulfurization company has all released the desulfur technology of oneself, but many indeterminable problems in actual application, have still been found, particularly the notice of up-to-date 2011 editions < < fossil-fuel power plant atmospheric pollutant emission standard > > and the special emission limit of execution atmosphere pollution, makes many enterprises will face the problem of desulphurization system secondary transformation.Although, patented technology about wet desulphurization absorption tower emerges in an endless stream, but in the face of still having many problems, new Environmental Protection Situation is badly in need of solving, state's inner desulfurization technology needs a kind of new technology to adapt to, and the utility model patent is bold in innovation and is had larger advantage in conjunction with the pluses and minuses of various desulfurization mainstream technologys.
At present, domestic application the most widely wet desulphurization absorption tower is spray column, as publication number a kind of wet flue gas desulfurization absorption tower that is 102225308A, adopt wet desulfurization of flue gas by limestone-gypsum method, comprise oxidation reaction pond and uptake zone two large divisions, below, absorption tower is provided with rounded oxidation reaction pond, and top is provided with the uptake zone being square, and establishes shotcrete pipe and the nozzle being connected with shotcrete pipe in bottom, uptake zone.Shotcrete pipe is concentric reducer pipe, and shotcrete pipe is connected with flange with nozzle.The established angle of the nozzle being connected with shotcrete pipe vertically upward.The oxidation reaction pond on absorption tower is that square inscribed circle is connected or square circumcircle connects with uptake zone sidewall connected mode, and shotcrete pipe and nozzle inspection manhole door are offered in Gang Bi uptake zone, absorption tower.The ceramic-lined oxidation air pipe of bottom, access oxidation reaction pond is pressed 15～20 ° of installations of form inclination that collar extension is high, internal orifice is low.It is simple, convenient that this technology has maintenance, reduces the technique effect of maintenance cost, but summary still has following problem to be badly in need of solving through long-term practice:
1, generally, the pressure of nozzle entrance slurries is higher, the atomization slurry particle diameter of ejection is less, the total surface area that flue gas is contacted with droplet is maximum, but because meticulous droplet is easily carried and pass secretly demister by flue gas, enter atmosphere and cause that PM2.5 exceeds standard, therefore the mist droplet particle size general control of the nozzle of spray column ejection is at average 2.5mm, owing to there being all the time certain distance interval between droplet, cannot guarantee that flue gas contacts with 100% of droplet, simultaneously because drop is less, drop internal flow is not obvious, this has just limited the use of spray column in sulphur coal situation.Particularly carrying out the special emission limit of atmosphere pollution area, environmental requirement SO
2concentration of emission must be lower than 50mg/Nm
3.For the higher coal of sulfur content, general sulfur content is 2.0% when above, and desulfuration efficiency need to reach more than 99%, and spray column cannot meet the demands.At present, there are many domestic desulfurizing items because of the desulfuration efficiency restriction of spray column, have to limit coal-fired sulfur content, to enterprise, increased huge operating cost.
Although to spray up and down angle be the nozzle of 90 ° to 2 spray columns all adopting near tower wall place, but cannot avoid the slurries of nozzle ejection to wash away tower wall, tower wall anticorrosive coat easily comes off like this, causes head tower wall erosion.
3, due to flue gas from the horizontal direction of spray column enter, horizontal direction draws, and cross section increases with capacity.Uptake zone coverage is short in addition, uptake zone velocity of flue gas is distributed and be difficult to evenly.On the other hand, due to the limitation of arrangement of nozzles, cause the desulfuration efficiency in spraying layer centre position higher than surrounding.Like this, the desulfuration efficiency of spray column cannot be stablized the level reaching more than 98.5%.
4,, in the situation that sulfur content is higher, in order to reach discharge standard, spray column adopts the method that increases the spray number of plies to solve conventionally, but adds to arrive 6 layers most.Like this, brought interlayer fine mist collision to become to interfere with each other greatly, adsorption tower smoke resistance significantly increases, loop slurry pump lift increases power consumption and increases and a series of adverse effects of repair and maintenance.
5, owing to entering into the flue dust particle diameter 10 μ m of inside, absorption tower, account for below 80%, 2.5 μ m account for 45% below, gas-liquid contact principle based on same, the efficiency of dust collection of spray column is generally about 50%, by the notice request of up-to-date 2011 editions < < fossil-fuel power plant atmospheric pollutant emission standard > > and the special emission limit of execution atmosphere pollution, like this, entrance dust concentration in absorption tower can not surpass 40～60mg/Nm
3, before nearly all absorption tower, electric cleaner and part sack cleaner need transformation.
Liquid column tower sulfur removal technology has embodied some advantages in actual applications in recent years, but because liquid column tower is square void tower, due to steel construction discontinuity throughout, need to increase many reinforcements and carry out rock-steady structure, like this, much more about the unitary steel material consumption of liquid column tower is 30% than spray column, limited the marketing of liquid column tower.
By long-term engineering design and operation practice, in conjunction with spray column and liquid column tower technology advantage separately, evade shortcoming separately, a kind of new economic benefits and social benefits smoke eliminator of final formation, not only avoided above-mentioned problem completely, and make whole desulphurization system construction investment still less, operating cost is lower, operation is more stable, and can meet when coal-fired sulfur content≤2.5% SO
2concentration of emission lower than 50mg/Nm
3the tightest up-to-date environmental requirement, fill up the technological gap of domestic Limestone-gypsum Wet Flue Gas Desulfurization Process technique superelevation desulfuration efficiency.Meanwhile, at smoke eliminator entrance dust concentration, be less than 80mg/Nm
3time can meet the tightest up-to-date soot emissions requirement.At present, the domestic desulfurizing item that is positioned at the execution special emission limit of atmosphere pollution area much all faces prior art transformation and cannot reach SO
2concentration of emission is lower than 50mg/Nm
3with smoke dust discharge concentration lower than 20～30mg/Nm
3situation.
