Description
Technical field
The utility model belongs to annular cooler technical field, is related to a kind of annular cooler high-temperature flue gas collecting hood.
Background technique
Annular cooler is widely used in the nodulizing process of the enterprises such as steel, nonferrous smelting, ore dressing.In order to efficiently use ring
The thermal energy of cooling mineral on shape cooler, it will usually be used to generate electricity by high-temperature flue gas collection.Common collection mode is in ring
Petticoat pipe is installed in the top of shape cooler, installs air draft pipe in the top of petticoat pipe, and pipeline connects exhaust fan, and exhaust fan is by high temperature cigarette
Pneumatic transmission enters electricity generation boiler power generation.Traditional petticoat pipe (as shown in Figure 1, Figure 2) be a section be rectangle a cabinet, petticoat pipe it is following
It is close with the breast board top of annular cooler, since petticoat pipe and annular cooler are cooling often in hot and cold alternation, and annular
The variation of position when machine is run, so in the following gap that can reserve 10-20mm between the breast board of annular cooler of petticoat pipe.
Since the cross-sectional sizes of petticoat pipe are consistent, air pressure is lower in the petticoat pipe near air draft pipe, the more flue gas in this section of region
It is taken out such as air draft pipe, the gap location between petticoat pipe and the breast board of annular cooler has more cold air to be inhaled into petticoat pipe.Far
Region air pressure from air draft pipe is higher, and flue gas is drawn into the less of pipeline.The sucking of petticoat pipe interior air-flow is uneven, has more cold
Air enters petticoat pipe by the gap between breast board and petticoat pipe, causes the flue-gas temperature for being sucked electricity generation boiler by exhaust fan lower,
Generated energy is lower.
Utility model content
In order to overcome the disadvantages mentioned above of the prior art, the utility model provides a kind of annular cooler high-temperature flue gas collection
The features such as cover, its structure is simple, cheap, easy for installation.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of annular cooler high-temperature flue gas is collected
Cover, including an outer petticoat pipe, are equipped with high-temperature flue gas collecting hood, high-temperature flue gas collecting hood center top is communicated in outer petticoat pipe
One air draft pipe, high-temperature flue gas collecting hood bottom are equipped with an air entry with high-temperature flue gas collecting hood equal length, air-breathing
Mouth lower end is placed with mineral, is equipped with breast board around mineral and intercepts.
The symmetrical stairstepping of high-temperature flue gas collecting hood, middle part highest area are maximum, toward outside height and area according to
Secondary reduction, collecting hood are erected in base cross members, and crossbeam is fixed on bracket by steel construction.
Pressure detecting meter is equipped in the outer petticoat pipe, according to the pressure in the outer petticoat pipe of pressure detecting meter detection, control
The revolving speed of induced draft fans, so that the air pressure in outer petticoat pipe is 0-50Pa bigger than atmospheric pressure.
The outer petticoat pipe is mounted on circular cooler trolley.
The beneficial effects of the utility model are: there are an air entry, high temperature section in the middle of high-temperature flue gas collecting hood bottom surface
Air entry air entry is big, and low-temperature zone air entry air entry is small；The area of section of the high-temperature flue gas collecting hood is to have in length direction
Variation, the area of section of the high-temperature flue gas collecting hood near exhaust column is larger, the high-temperature flue gas remoter apart from exhaust column
The area of section of collecting hood is smaller；It is equipped with pressure detecting meter in petticoat pipe, according to the data of pressure detecting meter, controls induced draft fans
Revolving speed so that the air pressure in petticoat pipe is 0-50Pa bigger than atmospheric pressure；It is sucked with traditional petticoat pipe ratio, this high-temperature flue gas collecting hood
Flue-gas temperature is high, and generated energy is big.
