Description
Affiliated technical field
The utility model belongs to smoke eliminator, especially adopts a kind of bispin stream impact type eddy flow plug of tobacco gas cleaning equipment.
Background technology
At present, the dedusting technology of domestic employing mainly contains the dust removal with machine technology, bag type dust removing technology, electrostatic precipitator technology and wet dust collection technology or the like.
The dust removal with machine device construction is simple and do not have moving component, so plant failure is few, operate easily and management, operating cost relatively low, investment cost is also less.But its ability of separating fine solid particle is more weak, thereby efficiency of dust collection is low.
Advantages such as exhaust dust device with bag has the efficiency of dust collection height, and stable, adaptability is strong.But to reasonably select filtrate for use in actual applications.Particularly the maintenance management requirement is very high, and in service will the maintenance according to the pertinent regulations of state in time found operating abnormal conditions and got rid of it, and device safety is normally moved.
Advantages such as electrostatic precipitator has the efficiency of dust collection height, and equipment resistance is little, applied widely, the smoke treatment air quantity is big.But it is bigger that it is once invested.
It is few that the wet dust removal device has an equipment investment, constructs fairly simplely, and efficiency of dust collection is than advantages such as height.But it need consume a certain amount of water (or liquid), can cause the secondary pollution of water in the dust removal process.Owing to be in operation, water (or liquid) can purify harmful poisonous gas, makes it that another kind of function arranged.Through taking adequate measures, can avoid the secondary pollution of water.
Current, adoptable desulfurization measure mainly contains: desulfurization in desulfurization before the burning, the burning, burning back desulfurization.
Desulfurization mainly refers to the coal washing desulfurization before the burning, can be divided into physics coal separation desulfurization, chemical coal separation desulfurization.Present industrial usefulness be the physics coal preparation method.
The physics coal separation mainly contains: coal jigging, heavy media coal separation, air dense medium fluid bed dry coal preparation, wind method, the coal separation of skewed slot bed etc.Mainly be to utilize in the coal density variation of organic and troilite and they are separated.Current, adopting many is coal jigging.But can only remove troilite sulphur in the coal with this kind method, and can not remove the organic sulfur in the coal.Thereby be not very high to desulfuration efficiency total in the coal.
Chemical desulfurization method mainly comprises: alkali desulphurization, gas sweetening, pyrolysis and hydro-desulfurization, oxidation desulfurization etc.
Alkali desulphurization mainly adds caustic alkali such as KOH, NaOH in coal, make the sulphur in the coal generate sulfur-containing compound under the certain reaction temperature, and this method has certain corrosivity.
Gas sweetening is at high temperature, with can with the gas treatment coal of pyrite in the coal or organic sulfur reaction, generate the volatility sulfurous gas, thereby slough the sulphur in the coal.
Physics doctor treatment, the desulfurization of chemical desulfurization method can obtain the low sulphur content coal of low ash, but because sulfur removal technology conditional request harshness, flow process complexity, investment and operating cost are expensive.
Desulfur technology is current in the burning mainly contains: industrial shaping coal burns with sulphur technology, fluidized bed combustion desulfur technology and furnace injection calcium base sorbent desulfur technology etc.
The solid sulphur of industrial shaping coal is to mix by a certain percentage to join desulfurizing agent and compression moulding in raw coal, and mixing the desulfurizing agent of joining in combustion process can be with part SO
2Be fixed up and reach the purpose of desulfurization.
Fluidized bed combustion desulfur technology and furnace injection calcium base sorbent desulfur technology all are in combustion process, mix on request and join a certain proportion of desulfurizing agent to reach the purpose of desulfurization.
Be that capturing sulfur briquette technology, fluidized bed combustion sulfur solidifying technique and furnace injection calcium base sorbent desulfur technology all need a cover corresponding apparatus, and desulfuration efficiency is not high.
Burning back desulfurization mainly is meant flue gas desulfurization, and the method for existing operation can be divided into dry type flue gas desulfurizing technology and wet flue gas desulfurization technology.
So-called dry type flue gas desulfurizing be meant the desulfurizing agent that no matter adds be dry state or hygrometric state, the final reacting product of desulfurization all is a dry state.The advantage of this technology is, compares with the wet type desulfurizing technology, and investment cost is lower, and desulfurization product is dry state, and mixes mutually with flying dust, need not to install demister and smoke re-heater, and equipment is not perishable etc.Its shortcoming is that the utilization rate of sorbent is lower, and is less economical when being used for sulphur coal, and the comprehensive utilization of lime-ash simultaneously also has certain difficulty.
So-called wet flue gas desulfurization technology is meant that sweetening process carries out in solution, desulfurizing agent and desulfurization resultant are hygrometric state.Its sweetening process is gas liquid reaction, has that desulphurization reaction speed is fast, efficient is high, the calcium utilization advantages of higher.But the reaction temperature of its sweetening process is lower than dew point, and the later flue gas of desulfurization generally needs could discharge from chimney through heat again.And equipment investment is higher, is suitable for the flue gas desulfurization of large-scale coal-fired power station boiler.
In sum, at large-scale coal fired power plant, dedusting and desulfurization are two parts, also do not have the sort of process two technology can be combined, and make equipment get final product dedusting, but desulfurization again.Realize dedusting and desulphurization integrated.And nearly 500,000 Industrial Boilers of whole nation operation also are main dust discharge and SO
2Pollution sources, the relevant dedusting technology, the desulfur technology that are suitable at large-scale coal fired power plant not exclusively are fit to Industrial Boiler again.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of bispin stream impact type eddy flow plate dust-removal and desulfurizing in one, efficient height, the smoke eliminator that drag losses is little, operating cost is low.
The technical solution adopted in the utility model is in order to achieve the above object: Wai Ta top is equipped with the scroll casing type flue, the bottom is provided with taper and removes ash bucket, interior tower is socketed on Wai Tazhong, the Nei Ta bottom is equipped with the snail port type cyclone, top is equipped with two-layer rotating stream tray, and nozzle is communicated with water feed apparatus and is arranged at rotating stream tray top, and interior top of tower is connected to the bending smoke outlet flue, the flue outlet place is equipped with moisture trap, receives air-introduced machine flue gas is entered chimney.
The utility model has the advantages that:
The utility model flue-gas dust-removing and desulfurization is fit to the equipment of China's medium small boiler control atmosphere pollution in the one purifier, but it can dedusting desulfurization again, realizes dedusting and desulphurization integratedly, and this device has advantages such as cost is low, and floor space is little, and operation maintenance is simple.This device dust removing effects can reach more than 98%, and reaching dust concentration is 100-200mg/nm
