Description
Technical field
The present invention relates to field of environment protection equipment more particularly to a kind of dynamical flue gas to take off white device.
Background technology
Waste gas purification（Flue gas purification）Be primarily referred to as industrial site generate industrial waste gas such as
The work that dust particle, flue gas flue dust, gas with foreign flavor, toxic and harmful gas are administered.Common waste gas purification has factory
Fume and exhaust gas purifying, workshop dust waste gas purification, organic waste-gas purification, the purification of exhaust gas peculiar smell, acid-base waste gas purifying, chemical emission
Purification etc..
Environmental and human health impacts are often generated adverse effect, should be taken before being discharged into air by the exhaust gas of industrial production discharge
Control techniques processing, is allowed to meet the requirement of waste gas emission standard, this process is known as waste gas purification.
Off-gas cleaning equipment is commonly utilized in chemical plant, Electronics Factory, spray painting factory, automobile factory, coating factory, petrochemical industry row
Industry, Furniture Factory, food factory, rubber plant, plastic cement factory etc. generate the industry of peculiar smell, stink, toxic and harmful gas.
Should be selected as the case may be in many equipment of waste gas purification expense is low, energy consumption less, non-secondary pollution, as possible
Accomplish to save energy consumption, it is environmental.
The processing of exhaust gas should carry out in terms of two：First, for the waste gas dedusting of suspension particulate contaminant；Second is that being directed to gas
The control of the waste gas purification gaseous pollutant of state pollutant mainly utilizes physico-chemical property, such as solubility, adsorption saturation degree, dew point
And the difference of selection chemical reaction etc., pollutant is separated from exhaust gas；Or pollutant is converted into harmless or is easy to
The substance of processing.The basic skills of waste gas purification has absorption process, absorption method, condensation method, catforming and combustion method etc..
The Treatment process that the Treatment process of atmosphere pollution summarizes atmosphere pollution is important atmospheric environment protection countermeasuress.
Clean combustion technique is to reduce pollutant emission in combustion process and improve processing, burning, conversion and the dirt of fuel utilization efficiency
Contaminate the general name of all technologies such as emission control.Sulfur dioxide, nitrogen oxides and cigarette（Powder）Dirt is the main atmosphere pollution in China.
Reduce sulfur dioxide, nitrogen oxides and cigarette（Powder）The discharge of dirt, for protecting and improving atmospheric environment.It is not only extremely important.And
And it is very urgent.
As economic constantly advances, social is constantly progressive, and also brings more and more environmental problems.Industry
Flue gas is one of primary pollution source of air, and nitrogen, sulfur oxide can form deep-etching after being combined with water containing there are many
The acid solution of property, significant damage is brought to exhaust apparatus, to environment.
Currently, industrial smoke mainly has direct emission and discharges two kinds of forms again after wet desulphurization.The work of direct emission
Industry flue gas, temperature is high, humidity is low, can keep the drying of chimney, to not cause significantly to corrode to chimney, however it is this
Nitrogen, sulfur oxide content are high in flue gas, and environmental pollution is larger.In contrast, it is many-sided that environmental protection and cost of investment etc. are based on
Consider, the Wet chimney scheme of wet desulphurization is carried out to flue gas, is still presently the most the mode of approval.
However Wet chimney scheme remains certain problem, wet desulphurization can remove the oxygen of most of sulphur in flue gas
Compound is but difficult to and completely eliminates pollutant in flue gas.And wet desulphurization can to introducing a large amount of vapor in flue gas,
Form the Low Temperature Wet white cigarette containing pollutant.This Low Temperature Wet white cigarette easily condenses in inner wall of stack, forms the acidity of strong corrosive
Solution causes serious corrosion to inner wall of stack.Simultaneously as temperature is low, nitrogen, the sulfur oxide contained in flue gas is difficult to expand
It dissipates, it is cumulative, it can also be polluted caused by surrounding enviroment.Therefore, to the flue gas after desulfurization carry out it is de- dehumidify in vain it is very necessary.
Existing flue gas takes off white device, and working efficiency can still be improved.Existing structure uses it in long-time
Afterwards, it is necessary to replace crucial exhaust-gas treatment module.And during replacing, it is necessary to stop work, and need to remove a large amount of
Part can replace core component, time-consuming and laborious, and can not be automated, and a large amount of manpower is needed to carry out.
