Cyclone dust collectors 42 are dust-contained airflow is made high speed rotary motion, by the effect of centrifugal force by particulate matter from air-flow It is middle to separate and collect the dust arrester to get off.Decline into the dust-contained airflow of cyclone dust collectors 42 along simplified inwall in rotation, Have that a small amount of gas is radially movable into central area simultaneously, when swirling eddy most of is reached near cone base, then Start to switch to move upwards, central area rises in rotation, is finally discharged by outlet, while there is also the radial direction of centrifugation Motion.Downward outer ring air-flow will generally be rotated and be referred to as outer vortex, and the region of cone base is called recirculating zone or mixed flow Area.

Contained particulate matters progressively settle under the influence of centrifugal force in rotary movement in the flue gas of cyclone dust collectors 42 Grow sturdily on the inwall for applying dirt device, and under the promotion of outer vortex and Action of Gravity Field, most of particulate matter gradually lands along cone inwall Into ash bucket.In addition, the small part air-flow in inlet air flow rotates upward, after top end cover and continuation edge in arrival along simplified inwall Export pipe outer wall rotation to decline, finally reach the air-flow that outlet lower end is raised and take away.Generally this fraction is claimed For upper vortex.With upper vortex, there will be a small amount of fine particle to be taken away upwards by interior vortex.Equally, also there is few portion in mixed flow region Divide fine particle to be taken up upwards by interior vortex, and partly taken away.Cyclone dust collectors 42 are exactly to complete particle through the above way The trapping of thing.The particulate matter trapped is located in the ash bucket of deduster bottom, from deduster discharge can be still contained in gas Part tiny particles content.

The form of cyclone dust collectors 42 is more, different in the way of air-flow enters, and can be roughly divided into and tangentially enter and axially enter Enter two major classes.Promote flow rotation by guide vane axially into formula, therefore also make guide vane rotary.Axially into Formula can be divided into reverse-flow and single flow again.Tangential entry type is divided into the forms such as straight people's formula and scroll casing type again：The inlet tube of straight people's formula Outer wall is tangent with cylinder；And the entrance inside pipe wall and cylinder of scroll casing type are tangent.My company removes using tangential direct-insert whirlwind Dirt device 42.

Cyclone dust collectors 42 are applied to non-sticky of the purification more than 1-3 microns, the dried dust of non-fiber.It is a kind of knot Structure is simple and convenient to operate, the cleaning equipment of high temperature resistant, cost of equipment and resistance higher (80~160 millimeter of water), cyclone dust removal Device 42 is applied the most extensive in cleaning equipment.

In incineration firing smoke exhaust process, active carbon filtration sandwich layer is mounted with charcoal absorption tower, be it is a kind of by Outward appearance made of carbonaceous material is in black, and internal pore structure is flourishing, specific surface area is big, a kind of microcrystalline carbon of adsorption capacity by force Cellulosic material.There are a large amount of invisible micropores in absorbent charcoal material, total internal surface area of micropore can be high in 1 gram of absorbent charcoal material Up to 700~2300 square metres, that is to say, that in the activated carbon granule of a grain of rice size, the internal surface area of micropore equivalent to The size of one stateroom inner wall surface.Exactly these micropores enable the various toxic and harmful gas of activated carbon " seizure " and impurity. Activated carbon suction tower has played key decomposition flue gas in garbage incinerating system, when activated carbon molecule and pernicious gas contact, Physical absorption adsorption strength it is mainly relevant with the physical property of activated carbon.Because Van der Waals force is weaker, to contaminant molecule Structure influence little, physical absorption can be analogized to coacervation by this power as intermolecular cohesion.Physical absorption When pollutant chemical property remain in that it is constant.

Because chemical bond is strong, the structure of contaminant molecule is had a great influence, therefore chemisorbed can be regarded as chemical reaction, is The result of chemical action between pollutant and activated carbon.Chemisorbed generally comprises electronics and shared or electronics is shifted, rather than letter Single perturbation or weak polarization, are irreversible chemical reaction processes.Adsorption process is that contaminant molecule is adsorbed to solid The process on surface, the free energy of molecule can reduce, and therefore, adsorption process is exothermic process, and the heat released is referred to as the pollutant Heat of adsorption on this surface of solids.Because physical absorption is different with the active force of chemisorbed, they are in heat of adsorption, absorption speed Rate, activation energy of adsorption, adsorption temp, selectivity, the absorption number of plies and absorbance spectrum etc. show certain difference.

Active carbon adsorption technology is used for purification of air at home, medicine, and the refined and decolouring of the industry such as chemical industry and food is There is history for many years.Start the seventies to be used for Industrial Wastewater Treatment.Production practices show that activated carbon is to trace toxic gas in flue gas Adsorptivity with brilliance, it has good to industrial wastewaters such as textile printing and dyeing, dye chemical industry, food processing and organic chemical industries Adsorption effect.Generally, to the organic matter represented in cigarette with overall targets such as BOD, COD, such as conbustion synthesis dyestuff, surface Property agent, phenols, benzene class, organochlorine, fired in plastic products etc., have the removal ability of uniqueness.So active carbon adsorption is Progressively turn into one of incineration treatment of garbage discharge main method.

It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with the power The protection domain that profit requires is defined.
