Description
Technical field
This utility model is related to the unpowered cigarette cooler of ozone denitration.
Background technology
The energy consumption per unit that China " 12 " planning outline is proposed declines 16%, CO2 emission drop
Low by 17%, total emissions of major pollutants reduces 8～10%.
" 12 " are the critical periods of China's socio-economic development transition, realize that low carbon development, Green Development are " 12
Five " theme of development.But due to the particularity of China's energy resource structure, within considerable time, once can based on coal
Source supply pattern will not occur essence change.Generally speaking, during " 12 ", energy demand can also keep rapid growth
Situation, according to State Grid's project study center with regard to《Long-term generating capacity and electricity needs development prediction in China》, by
In the end of the year 2013, China's coal electricity installed capacity is 8.47 hundred million kilowatts.Hundred million kilowatts of the year two thousand thirty coal Denso machine 12.5-14 of prediction；The year two thousand fifty
Hundred million kilowatts of coal Denso machine 14-15.Large-scale coal fired power generation can be brought than now more serious environmental problem.
Ozone denitration, currently as domestic main flow denitrating technique, market share is high, and arrangement is convenient, by user's
Consistent favorable comment.Ozone denitration is unpowered cigarette cooler also necessarily possesses the city of light as the indispensable equipment of ozone denitration
Field prospect.
Because ozone denitration is larger to the sensitivity of flue-gas temperature, the life cycle of mainly ozone is related to denitration efficiency
Height, under 150 DEG C of cryogenic conditions, the resolution ratio of ozone is not high, but with temperature increase, ozone decomposed speed accelerate,
When temperature is higher than 200 DEG C, resolution ratio is dramatically increased.And general carbon black tail gas kiln gas feature is that temperature is high, high humidity, temperature
Up to 220 DEG C, humidity is up to 35%.Obviously the temperature can not meet the temperature window of ozone denitration, and its smoke moisture is again
Very big, using conventional spray cooling DeGrain, and water spray can also bring the danger of back-end ductwork rust corrosion.

Pressure hole, between the import pressure tap and outlet pressure tap differential pressure gauge is connected with.
The unpowered cigarette cooler of ozone denitration of the application is primarily directed to the ozone denitration engineering of carbon black tail gas kiln gas,
Wherein flue gas storehouse design different from the past, is provided with exhaust gases passes and cold air channel in flue gas storehouse, be vertical between two passages
Directly it is distributed and is not in contact with each other, the heat exchanging process for absorbing flue gas heat by cold air is discharged after flue-gas temperature is reduced, cold sky
Gas is raised because absorbing temperature after heat, is discharged by top aiutage.Due to ozone denitration produce carbon black smoke containing flue dust it is few,
Cigarette cooler need not be cleared up at ordinary times almost without dust stratification, as long as clearing up during overhaul.Can be by former cigarette using the equipment
Temperature degree is reduced to 120 DEG C or so by 220 DEG C.
The unpowered cigarette cooler of ozone denitration of the application is specifically, point fume side and air side, fume side：High-temperature flue gas from
Equipment left side enters gas approach, through one group of convection tube group cooling (facial heat exchange), low-temperature flue gas from equipment right side out,
Remove follow-up ozone denitration activity molecular reactor；Air side：Cold air from equipment bottom enter, through convection tube group inner side with
Flue gas carries out facial heat exchange, and hot-air utilizes difference in specific gravity, flows out from pipe group top, and then classical prescription round knot collects to top vent
Cylinder, enters air.
Further, the convection tube group is slender rectangular tube, the length of side in the diameter of the convection tube group and the flue gas storehouse
Than for 1:20-50.
Further, the lower end size of the circumference section matches with the top-side size in the flue gas storehouse；The aiutage
Lower end size with it is described circumference section upper end size match.
Further, the flue gas storehouse, side sealing plate, upper sealing panel, lower sealing plate, convection tube group, compressed air fluidisation
The material of pipe, fluidisation arm, ball valve, circumference section and aiutage is ND acid resisting steels or 304 rustless steels.
The application utilizes pipe close, flue gas chilling temperature can be manually adjusted, by being arranged on high-temperature flue gas import passage
Import bimetallic thermodetector and be arranged on low-temperature flue gas exit passageway outlet bimetallic thermodetector enter to travel out flue gas
Temperature monitoring, when needing to reduce flue gas amount of cooling water, jumps a queue pipe close in semiconvection bottom of the tube, makes the convection current seal of tube, then whole
Individual cigarette cooler heat convection area is reduced；When needing to increase flue gas amount of cooling water, then convection tube bottom pipe close, stronger ventilation are removed
Amount, increases cooling effect.The unpowered cigarette cooler of ozone denitration of the application is directed to carbon black tail gas kiln gas, and itself is ashless
Dirt, when having dirt accumulation in flue gas storehouse, can be measured by differential pressure gauge, and differential pressure is raised, and has illustrated dirt accumulation, only need to one by one open ball
Valve carries out the Air Fluidized of a period of time, and the dust in flue gas orlop portion is fluidized, and the dust of accumulation can float with flue gas stream.
Using 304 rustless steels or ND acid resisting steels, material is easy to get each component materials of the application, buying facilitates.Convection duct is because using
Material is good, not perishable, is the most reliably, such as truly there is that pipe is rotten to be worn, as long as then jumping a queue pipe close in the tube bottom end,
Entirety is not affected to use, just because of the property durable in use of the unpowered cigarette cooler of the ozone denitration, is especially suitable for not allowing to stop temporarily
The white carbon black industry of machine.
There is steam power plant to reclaim come cooled flue gas and by the partial heat using desalination water as medium at present, but often in charcoal
Black industry, first, the demineralized water of this part heating does not have occasion to use, second, once water pipe explosion can cause full factory to shut down, on the contrary
Increased the burden of white carbon black enterprise.
Moisture content due to not increasing flue gas, reduces the corrosion to back-end ductwork, so the application is substantially better than routine
Cooling spray system.If necessary to the heat using heat exchange in the application, as long as then the hot-air is introduced using blower fan
Combustion system.
