Background technique
Currently, northwest China region coal fired thermal power plant flue is mostly rectangular flue, double air-introduced machine exhaust pass needs converge,
Become larger due to converging rear pass section, meet flue common design is sudden expansion structure and lacks guiding device, easily leads to and converges
Local eddy currents, flow of flue gas are uneven afterwards, so that local resistance loss, air-introduced machine power consumption be caused to increase.Therefore, converge flue into
The reasonable water conservancy diversion of row is of great significance.
Summary of the invention
The utility model aims to solve the problem that the above problem, provides a kind of simple novel guide of structure and converges flue.
Novel guide described in the utility model converges flue, including flue collector, further include flaring flue, converge flue and
Deflector；The flue collector includes the first flue collector and the second flue collector；The flaring flue includes the first flaring flue and the
Two flaring flues；First flue collector is connected with the second flue collector in the horizontal direction by the first flaring flue；It is described
Converge flue to be connected with the second flue collector in vertical direction by the second flaring flue；It is main that the deflector is set to second
In flue, positioned at the top of the second flaring flue.The longitudinal section area of the first flaring flue and the first flue collector connecting pin
Greater than the longitudinal section area of the first flaring flue and the second flue collector connecting pin；Second flaring flue and converge flue connect it is extreme
Longitudinal section area realizes the utility model institute less than the area of the second flaring flue and the second flue collector connecting pin longitudinal section according to this
The novel guide stated converges flue caliber of the flue on flow of flue gas direction and gradually expands.
Novel guide described in the utility model converges flue, and the deflector is obliquely installed to the tail end of the second flue collector
In in the second flue；By being obliquely installed, the flue gas converged in flue is guided to the second flue collector.
Novel guide described in the utility model converges flue, and the longitudinal section of the deflector is arc-shaped.
Novel guide described in the utility model converges flue, and the deflector includes the first arc water conservancy diversion being arranged in the same direction
Plate and the second arc deflector；First arc deflector and the second arc deflector are set in turn in the second flue collector.
Novel guide described in the utility model converges flue, and flaring flue is arranged by the tail end in the first flue collector,
Small bore flue is connected into heavy in section second flue collector after the flaring of flow of flue gas direction, is led in flue meet setting arc
Flowing plate, slowed down by flue racing turn, the means of flue cross section flaring, improve the flowing off-set phenomenon of flue gas deflecting, reduce cigarette
Gas eddy stream reduces local resistance loss.
Detailed description of the invention
Fig. 1 is one structural schematic diagram of embodiment that novel guide described in the utility model converges flue；
Fig. 2 is two structural schematic diagram of embodiment that novel guide described in the utility model converges flue；
Fig. 3 is the using effect comparison diagram that novel guide described in the utility model converges flue；
Wherein the first flue collector of 1-, the second flue collector of 2-, the first flaring of 3- flue, the second flaring of 4- flue, 5- converge cigarette
Road, 6- deflector, the first arc deflector of 7-, the second arc deflector of 8-.
Specific embodiment
Converge flue to novel guide described in the utility model with reference to the accompanying drawings and embodiments to be described in detail.
Implement one
Novel guide described in the utility model converges flue, as shown in Figure 1, including flue collector, flaring flue converges cigarette
Road 5 and deflector 6；The flue collector includes the first flue collector 1 and the second flue collector 2；The flaring flue includes the first flaring
Flue 3 and the second flaring flue 4；First flue collector 1 by the first flaring flue 3 in the horizontal direction with the second flue collector
2 are connected；The flue 5 that converges is connected with the second flue collector 2 in vertical direction by the second flaring flue 4；It is described to lead
Flowing plate 6 is set in the second flue collector 2, positioned at the top of the second flaring flue 4.The first flaring flue 3 and the first main cigarette
The longitudinal section area of 1 connecting pin of road is greater than the longitudinal section area of 2 connecting pin of the first flaring flue 3 and the second flue collector；Second gradually
Expand flue 4 and converge flue 5 and connects extreme longitudinal section area less than vertical section of the second flaring flue 4 and 2 connecting pin of the second flue collector
The area in face, deflector 6 are obliquely installed to the tail end direction of the second flue collector 2 in the second flue collector 2, deflector 6 and horizontal
Face forms one 45 ° of angles；The lower end of deflector 6 is connected with the side wall of the second flaring flue 4；The two sides of deflector 6 and second
The inner wall of flue collector 2 is fixedly connected.
Novel guide described in the utility model converges flue, by be arranged flaring flue, the flue gas for converging flue 5 into
It is fashionable, through the first flaring flue 3 and the second flaring flue 4 cross-sectional area of second flue collector 2 is expanded, while passing through water conservancy diversion
The flue gases that 6 pairs of plate enters through the second flaring flue 4 carry out water conservancy diversion, so that converging flue gas in flue 5 after the second flaring flue 4
Flue gas direction in the first flue collector 1 enters, and improves the flowing off-set phenomenon of flue gas deflecting, reduces flue gas vortex, reduces
Local resistance loss effectively improves the smoke evacuation ability of flue.
Embodiment two
On the basis of example one, novel guide described in the present embodiment converges flue, and deflector 6 includes being arranged in the same direction
First arc deflector 7 and the second arc deflector 8；First arc deflector 7 and the second arc deflector as shown in Figure 2
8 are set in turn in from left to right in the second flue collector 2, the two sides and second of the first arc deflector 7 and the second arc deflector 8
The inner wall of flue collector 2 is fixedly connected.The tangent line for the junction that the lower end of first arc deflector 7 is connected with the second flue collector 2
One 60 ° of angles are formed with horizontal plane；The lower end of the arc-shaped outer surface of second arc deflector 8 is connected with the second flue collector 2
The tangent line and horizontal plane of junction form one 50 ° of angles.By the first arc deflector 7 and 8 pairs of the second arc deflector through
The flue gas that two flaring flues 4 enter carries out water conservancy diversion, so that converging flue gas in flue 5 after the second flaring flue 4 along first
Flue gas direction in flue collector 1 enters, and experiment effect comparison diagram as shown in Figure 3 is as it can be seen that the flowing for improving flue gas deflecting deviates
Phenomenon reduces flue gas vortex, reduces local resistance loss, effectively increase the smoke evacuation ability of flue.
