Abstract
The utility model discloses a smoke removing passage of multi-storey buildings, which comprises a main smoke passage (1) and an auxiliary smoke passage (2). The utility model is characterized in that the forming cross section of the auxiliary smoke passage (2) forms an arc shape, and a diversion section (3) of the auxiliary smoke passage (2) forms a cone shape. The smoke removing improves the structural shape of the auxiliary smoke passage and the diversion section, the utilization rate of the cross section can be effectively improved, the flow resistance of the auxiliary smoke passage is reduced, resistance in merging can be reduced, and the residual end of the auxiliary smoke passage can be sufficiently used. The utility model can reduce the whole occupation space of the smoke removing passage under the effect that the same smoke removing is satisfied. The utility model has the characteristics of simple structure, favorable smoke removing effect, small size and small occupation space, and can be used for multi-storey buildings and used as a smoke removing and gas removing device.
Description
Technical field
The utility model relates to smoke evacuation, the exhaust plant that a kind of multi-storey building is used.
Background technology
At present, for smoke evacuation, the exhaust effect that improves multi-storey building, method commonly used is, is that every layer of resident family increases an auxillary flue in the shared flue collector of multilayer.The flue gas of each layer resident family collects in flue collector again and discharges after auxillary flue is separately discharged.Existing auxillary flue cross section is quadrangle basically, and the diversion section between the two-layer auxillary flue is a swash plate.The smoke vent of this structure, the flow resistance of major and minor flue is bigger, reach satisfied smoke discharging effect and consolidate, and the integral body of smoke vent takes up room bigger.Because smoke vent will take the architectural space of building, so the builder always feels not too satisfied.
Summary of the invention
The purpose of this utility model is: the smoke vent that provides a kind of new multi-storey building to use.This smoke vent both can satisfy the smoke evacuation requirement, and the integral body that has reduced smoke vent again takes up room.
The technical solution of the utility model: the smoke vent that multi-storey building is used, structure comprises flue collector 1, auxillary flue 2; It is characterized in that: the formation cross section of auxillary flue 2 is an arc, and it is conical that the diversion section 3 between the auxillary flue 2 is.
In the smoke vent that above-mentioned multi-storey building is used, the taper shape that the diversion section 3 between the auxillary flue 2 is is that tapering is the taper shape of 20-30 degree.
Compared with prior art, the utility model has improved the planform of auxillary flue and diversion section.Adopt conical water conservancy diversion, the resistance in the time of can reducing to collaborate makes full use of the residue end of auxillary flue.Arc is adopted in the formation cross section of auxillary flue, can effectively improve the cross section utilization rate, reduces the flow resistance of auxillary flue.The utility model is satisfying under the same smoke discharging effect, and the integral body that can reduce smoke vent takes up room.Have characteristics simple in structure, that smoke discharging effect good, volume is little, saving takes up room.Can be used in the multi-storey building, use as smoke evacuation, exhaust plant.
Description of drawings
Accompanying drawing 1 is the structural representation of utility model;
The specific embodiment
Embodiment.As shown in Figure 1, the smoke vent structure used of multi-storey building comprises flue collector 1, auxillary flue 2; The arc section (referring to accompanying drawing 2) of approximate garden shape is adopted in the formation cross section of auxillary flue 2 (both having increased part on flue collector), and the diversion section 3 between the auxillary flue 2 is the taper shape that tapering is the 20-30 degree.Auxillary flue 2 is adopted conical water conservancy diversion, and the resistance in the time of can reducing auxillary flue 2 flue gases and enter flue collector 2 interflow makes full use of the residue end of auxillary flue 2.Arc is adopted in the formation cross section of auxillary flue 2, can effectively improve the cross section utilization rate of auxillary flue 2, reduces the flow resistance of flue gas in the auxillary flue 2.Above measure can totally improve the effect that smoke vent is got rid of flue gas.Under same taking up room, smoke discharging effect of the present utility model is significantly better than existing other smoke vent.
Claims (2)
1, the smoke vent used of multi-storey building, structure comprises flue collector (1), auxillary flue (2); It is characterized in that: the formation cross section of auxillary flue (2) is an arc, and it is conical that the diversion section (3) of auxillary flue (2) is.
2, the smoke vent used of multi-storey building according to claim 1, it is characterized in that: the taper shape that the diversion section (3) of auxillary flue (2) is is that tapering is the taper shape of 20-30 degree.
