Abstract
The utility model proposes a kind of chilling tower, wherein, the chilling tower includes：Smoke inlet；Flue gas dispersal device connects the smoke inlet；Cooling device including multiple atomizers, is uniformly distributed in the chilling top of tower；Wherein, the flue gas dispersal device includes：Divide flue；Buffler is set to described divide in flue；Lower end-stopping plate is set to and described divides flue lower end；Advantageous effect：According to the flue gas dispersal device that nozzle quantity separates flue setting, exhaust gases passes respectively are formed, make flow of flue gas more uniform.Each channel is connected with chilling tower, and is corresponded with nozzle, spray water is allowed fully to cover chilling tower flue gas entrance, so as to improve the contact heat transfer of spray water and flue gas.
Description
Technical field
The utility model is related to incineration of waste field more particularly to a kind of chilling towers.
Background technology
Chilling tower is an important equipment in hazardous waste burn system, incineration flue gas during cooling easily again
Bioxin is formed, the effect of chilling tower is that flue gas cools down rapidly in a short time by way of water cooling, destroys bioxin again
The temperature range of formation, synthesizes again to avoid it.
Chilling pressure tower atomizer atomizes water into the droplet of diameter very little, directly carries out mass-and heat-transfer friendship with flue gas
It changes, the moisture evaporation of spray is made using the heat of flue gas, so as to which flue gas be made to be cooled to 200 DEG C or so rapidly in tower, flue gas exists
Residence time in chilling tower is less than 1s.
In prior art construction, chilling tower entrance is an elbow, and flue gas is directly entered chilling tower ontology through the elbow, at this time
Smoke distribution is uneven, it will makes a certain region flue gas flow bigger than other regions, the corresponding heat that it is carried is also more.It is right
For the nozzle being evenly arranged, the more regional temperature reduction of those heats will slow down, so as to lead to temperature fall time
Extra bioxin is generated more than 1s.In addition, ash is also easily made to be attached to chilling tower wall face so as to corrode inner wall, thus hold
Easily cause various failures.
Utility model content
For the above-mentioned problems in the prior art, it is proposed that a kind of chilling tower, wherein, the chilling tower includes：
Smoke inlet；
Flue gas dispersal device connects the smoke inlet；
Cooling device including multiple atomizers, is uniformly distributed in the chilling top of tower.
Wherein, the flue gas dispersal device includes：
Divide flue；
Buffler is set to described divide in flue；
Lower end-stopping plate is set to and described divides flue lower end.
Wherein, it is described that flue is divided to divide flue made of carbon steel.
Wherein, described that flue interior surface is divided to include a flame retardant coating, the flame retardant coating includes a variety of refractory materials.
Wherein, the buffler is buffler made of carbon steel.
Wherein, the buffler surface includes a flame retardant coating, and the flame retardant coating includes a variety of refractory materials.
Wherein, the lower end-stopping plate lower end-stopping plate made of carbon steel.
Wherein, the lower end baffle surface includes a flame retardant coating, and the flame retardant coating includes a variety of refractory materials.
Wherein, it is described to divide flue with the buffler by being welded to connect.
Wherein, the flue gas dispersal device uses flanged joint with the cooling device.
Advantageous effect：According to the flue gas dispersal device that nozzle quantity separates flue setting, exhaust gases passes respectively are formed,
Make flow of flue gas more uniform.Each channel is connected with chilling tower, and is corresponded with nozzle, and spray water is allowed fully to cover chilling
Tower flue gas entrance, so as to improve the contact heat transfer of spray water and flue gas.The sectional area of gas approach is reduced, makes each nozzle
Spraying covers entire inlet flue gas flow section, will not form dead zone.Final Shi Ge areas temperature fall time is identical, can realize 1S with
Inside it is reduced to less than 200 DEG C.
