Abstract
The utility model discloses one kind without internal overarm support rectangle cigarette ducting system, truss including cigarette air channel body and some loop configuration, wherein, the truss of each loop configuration is socketed on the outer wall of cigarette air channel body successively vertically, and the bottom of the truss of loop configuration is provided with some suspension and supports, some reinforcing ribs are provided between the truss of two neighboring loop configuration, and reinforcing rib is arranged on the outer wall of cigarette air channel body, each reinforcing rib is axially distributed, and each truss of the reinforcing rib with each loop configuration is connected, the SR is small, cigarette air duct flow field is uniform, cost of investment is low, floor space is small, it is and easy to wear in the absence of internal overarm support, easy dust stratification and flaky problem.
Description
Technical field
The utility model belongs to cigarette air channel technical field, is related to one kind without internal overarm support rectangle cigarette ducting system.
Background technology
The suspension and support spacing in conventional rectangular cigarette air channel is 6~9m, and to support cigarette air channel, cigarette air channel branch is equipped with suspension and support
Frame, thus bring the problems such as construction investment cost is high, floor space is big.
Conventional rectangular cigarette air channel is equipped with internal overarm support, thus bring cigarette ducting system resistance is big, cigarette air duct flow field is uneven,
The problems such as internal overarm support easy dust stratification easy to wear.For Anti-corrosive smoke canal, also there is that the anticorrosive construction at internal overarm support is difficult, prevents at internal overarm support
Rotten the problems such as easily peeling off, and once destruction will cause considerable damage to anticorrosive coat to the general safety of flue structure.
Utility model content
The shortcomings that the purpose of this utility model is to overcome above-mentioned prior art, there is provided one kind is without internal overarm support rectangle cigarette wind
Road system, the SR is small, cigarette air duct flow field is uniform, cost of investment is low, floor space is small, and is easily ground in the absence of internal overarm support
Damage, easy dust stratification and flaky problem.
To reach above-mentioned purpose, no internal overarm support rectangle cigarette ducting system described in the utility model include cigarette air channel body and
The truss of some loop configuration, wherein, the truss of each loop configuration is socketed on the outer wall of cigarette air channel body successively vertically, and
The bottom of the truss of loop configuration is provided with some suspension and supports, passes through some reinforcing ribs between the truss of two neighboring loop configuration
Connection, and reinforcing rib is arranged on the outer wall of cigarette air channel body, each reinforcing rib is circumferentially distributed.
The truss equidistantly distributed of each loop configuration.
Each reinforcing rib between the truss of two neighboring loop configuration is parallel and equidistantly distributed.
The cross section of cigarette air channel body is quadrilateral structure.
The suspension and support equidistantly distributed of the truss bottom of same loop configuration.
The periphery of the truss of loop configuration is rectangular configuration.
Heat-insulation layer is provided with the outer wall of cigarette air channel body and on the outer wall of the truss of loop configuration.
The utility model has the advantages that：
No internal overarm support rectangle cigarette ducting system described in the utility model includes cigarette air channel body and some loop configuration
Truss, wherein, the truss of each loop configuration is socketed on the outer wall of cigarette air channel body, so as to ensure that the safety of cigarette air channel body is steady
It is fixed, the transmission of cigarette wind medium is realized, in addition, the utility model also includes some reinforcings being arranged on the body outer wall of cigarette air channel
Rib, the reinforcing to cigarette air channel body is realized by each reinforcing rib, so as to avoid setting internal overarm support in cigarette air channel body interior, and then
Thoroughly avoid internal overarm support easy to wear, easy dust stratification and flaky problem.In addition, the bottom of the truss of loop configuration be provided with it is some
Suspension and support, the set location and setting spacing of suspension and support are unrestricted, and then save suspension and support, reduce cost of investment and take up an area face
Product, make factory building layout more rationally attractive in appearance, by taking the flue of one section of 20m length in coal-burning power plant's 300MW units as an example, reduce investment
About 600,000 yuan of cost, reduce and take up an area about 200m2.Due to, without internal overarm support, optimizing cigarette air duct flow field inside cigarette air channel, reducing cigarette
Resistance in air system, according to statistics, the resistance of the straight length about 60% in cigarette air channel can be saved, reduce operation power consumption, solve internal overarm support
Dust stratification and wear problem, improve the service life in cigarette air channel so that the anticorrosive construction difficulty of Anti-corrosive smoke canal is greatly reduced, prevented
Detritus amount significantly improves.
