Description
Technical field
The utility model belongs to vacuum boiler technical field, and in particular to a kind of integrated flue gas recycles low nitrogen condensation
Vacuum boiler.
Background technology
As shown in Figure 1, the burning in 1 front of shell cylinder is arranged by shell cylinder 1 in existing low nitrogen condensate vacuum boiler
Out of stock module 3 at 1 rear of shell cylinder, condenser 4, burner hearth 5, the flue being arranged in shell cylinder 1 is arranged in device 2
6, the composition of smoke-box 7 is returned.Burner hearth 5 is arranged in the underface of flue 6, and face burner 2, the tail end face of flue 6
Out of stock module 3 returns smoke-box 7 and the front in burner hearth 5 and flue 6 is arranged.The flow of flue gas route that burner 2 generates is burner hearth
5, smoke-box 7, flue 6, out of stock module 3, condenser 4 are returned, is finally discharged into air.
Main problem is existing for the structure：The temperature of boiler combustion is usually at 2000 DEG C or more, and ignition temperature is once
The NO then generated higher than 1500 DEG CxContent is more, needs individually to be equipped with the out of stock processing of out of stock module progress, to reduce discharge flue gas
In nitrogen content, and manufacturing cost is high；Out of stock module and condenser are located at outside shell cylinder, and occupied space is big, is not easy to install.
Utility model content
The utility model is intended to reduce the manufacturing cost of vacuum boiler, reduces occupied space, and reduces in discharge flue gas
Nitrogen content.
For this purpose, technical solution used by the utility model is：A kind of integrated flue gas recycles low nitrogen condensate vacuum pot
Stove, including shell cylinder, burner, condenser, burner hearth, flue and time smoke-box, the burner are arranged in shell cylinder
Front, burner hearth, flue and return smoke-box and be arranged in shell cylinder, burner hearth is arranged in the underface of flue and face
Burner, returns smoke-box and the front in burner hearth and flue is arranged, and is provided with and turns at rearward position in the shell cylinder
Curved smoke-box is provided with longitudinal baffle in the turning smoke-box flue gas is made to get on, get off and flowed, the front end of flue gas recirculation pipe
It accesses in burner, the ante-chamber of the rear end access turning smoke-box of flue gas recirculation pipe, the condenser is mounted on turning smoke-box
Back cavity.
The smoke outlet communicated with the external world is provided at the top of the condenser as a preferred embodiment of the above solution, smoke-box of turning
Bottom be provided with " L " type drainpipe for communicating of the external world, and at the position that smoke-box bottom is connected with " L " type drainpipe of turning most
It is low, further save occupied space.
Further, the flue gas recirculation pipe is formed using steel plate bending, whole " U "-shaped, facilitates processing and manufacturing and peace
Dress.
The utility model has the beneficial effects that：Low-temperature flue gas after flue end is exchanged heat using flue gas recirculation pipe
It is reintroduced back in burner and is neutralized with high-temperature flue gas, to control the temperature of combustion product gases at 1500 DEG C hereinafter, reducing
NO in flue gasxContent, it is no longer necessary to be individually equipped with out of stock module, reduce manufacturing cost；Condenser is placed in shell cylinder
It is interior, it is arranged in turning smoke-box with the rear end time interval of flue gas recirculation pipe, it is compact-sized, it occupies little space.
Description of the drawings
Fig. 1 is the structural schematic diagram before improving.
Fig. 2 is improved structural schematic diagram.
Specific implementation mode
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail：
As shown in Fig. 2, a kind of integrated flue gas recycles low nitrogen condensate vacuum boiler, mainly by shell cylinder 1, burner
2, flue gas recirculation pipe 3, condenser 4, burner hearth 5, flue 6, time smoke-box 7 form.
Burner 2 is arranged in the front of shell cylinder 1, and burner hearth 5, flue 6 and time smoke-box 7 are arranged in shell cylinder 1
It is interior.Burner hearth 5 is arranged in the underface of flue 6 and face burner 2, returns smoke-box 7 and is arranged in burner hearth 5 and flue 6
Front.Described above consistent with existing vacuum boiler structure, details are not described herein.
Difference lies in：Turning smoke-box 9 is provided at rearward position in shell cylinder 1, is provided in smoke-box 9 of turning vertical
Make flue gas get on, get off to partition board 8 to be flowed.In the front end access burner 2 of flue gas recirculation pipe 3, flue gas recirculation pipe 3
Rear end access turning smoke-box 9 ante-chamber, condenser 4 be mounted on turning smoke-box 9 back cavity.
Preferably, the top of condenser 4 is provided with the smoke outlet 10 communicated with the external world, out of stock and condensed for discharging
Flue gas；The bottom of turning smoke-box 9 is provided with " L " the type drainpipe 11 communicated with the external world, and 9 bottom of smoke-box of turning is arranged with " L " type
It is minimum at the connected position of water pipe 11, facilitate discharge condensed water.
In addition, flue gas recirculation pipe 3 is formed using steel plate bending, it is whole " U "-shaped.
The flow of flue gas route that the burning of burner 2 generates is as shown by arrows in figure, is followed successively by burner hearth 5 → time 7 → cigarette of smoke-box
Feed channel 6 → turning smoke-box 9, later, part of smoke is introduced by flue gas recirculation pipe 3 in burner 2, another part flue gas
It after condensed device 4 condenses, is discharged into air from smoke outlet 10, the condensed water formed in condensation process is through " L " type drainpipe 11
Discharge.
