Abstract
The utility model discloses a gas boiler blow-off pipe which comprises a gas vertical pipe. The lower end of the gas vertical pipe is divided into two paths, one path is a drainage pipeline, the other path is a blow-off pipeline, and a plug board is fixed at the lower end of the blow-off pipeline. Due to the arrangement of the drainage pipeline and the blow-off pipeline, smooth accumulated water draining is facilitated, stability and safety of boiler gas combustion are guaranteed, and the phenomenon that in the prior art, the pipelines and valves are blocked because gas contains a great number of impurities and settlings is avoided. The plug board is fixed at the lower end of the blow-off pipeline and ensures the effect that gas leakage is cut off reliably, and moreover the plug board is opened for blow-off when a boiler is shut down.
Description
Technical field
The utility model relates to a kind of blow-off pipe, is specifically related to a kind of gas boiler blow-off pipe.
Background technology
Existing boiler coal gas blowdown, draining share a blow-off line, owing to containing a large amount of impurity and deposit in coal gas, cause coal gas blowdown, drainage pipeline, valve place often to stop up.Cause large quantity of moisture in coal gas to enter burner hearth or a large amount of impurity and deposit obstruction gas piping, cause gas regulator on pipeline, motor-driven valve, fast valve or manually operated door dust stratification serious, can't normal operating, affect unstability and the security of boiler coal gas burning.
The utility model content
The purpose of this utility model is to provide a kind of gas boiler blow-off pipe, and it is blowdown smoothly, can not stop up valve and pipeline.
For achieving the above object, the utility model adopts following technical scheme:
The utility model comprises gas riser, and described gas riser lower end is divided into two-way, and a road is drainage pipeline, and a road is blow-off line, and the blow-off line lower end is fixed with closure plate.
Described drainage pipeline is arranged at the below of one deck gas-fired arm of gas boiler.
Described blow-off line is arranged at the pipeline contraction place of gas riser below and is positioned at the below of drainage pipeline.
The described drainage pipeline other end causes water seal for coal gas.
Described drainage pipeline is provided with valve,
With respect to prior art, the beneficial effect the utlity model has: the utility model is by arranging two pipelines, a blow-off line, a drainage pipeline, being conducive to like this ponding discharges smoothly, guaranteed stability and the security of boiler combustion coal gas, avoided in prior art owing to containing a large amount of impurity and deposit in coal gas, thus the phenomenon of blocking pipe and valve; The blow-off line lower end is fixed with closure plate, ensures that reliably blocking coal gas leaks, and open closure plate with blowdown when blowing out.
Further, the below of one deck gas-fired arm of gas boiler arranges drainage pipeline, is beneficial to ponding and discharges, avoided because draining is unfavorable, causing winter ignition of the boiler point not icing, the seeping phenomenon of phenomenon or one deck gas-fired arm burner, pipeline.
Higher than the blow-off line arrangement principle, drainage pipeline is installed on to one deck gas-fired arm below according to drainage pipeline, is conducive to ponding and flows out by drainage pipeline.
Drainage pipeline causes water seal for coal gas, the moisture contained in coal gas can be caused to water seal for coal gas by drainage pipe, guarantees gas-fired stability, has avoided the de-fire of gas-fired, interrupted Ignition Phenomena.
The accompanying drawing explanation
Fig. 1 is existing gas boiler blow-off pipe schematic diagram;
Fig. 2 is the utility model structural representation.
Wherein, 1 is one deck gas-fired arm; 2 is two layers of gas-fired arm; 3 is three layers of gas-fired arm; 4 is gas riser; 5 is closure plate; 6 is blow-off line; 7 is drainage pipeline.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
Referring to Fig. 2, the utility model comprises gas riser 4, and gas riser 4 is communicated with three layers of gas-fired arm 3 from top to bottom successively, secondary gas-fired arm 2, one deck burning arm 1, gas riser 4 lower ends are divided into two-way, one tunnel is drainage pipeline 7, and drainage pipeline 7 is provided with valve; One tunnel is blow-off line 6, and pipeline contraction place and blow-off line 6 lower ends that blow-off line 6 is arranged at gas riser below are fixed with closure plate 5, to ensure that reliably blocking coal gas leaks, opens closure plate 5 with blowdown when blowing out.According to drainage pipeline 7 higher than blow-off line 6 arrangement principle, drainage pipeline 7 is installed on to one deck gas-fired arm below 1, be conducive to ponding and flow out by drainage pipeline 7, avoided because draining is unfavorable, causing winter ignition of the boiler point not icing, the seeping phenomenon of phenomenon or one deck gas-fired arm 1 burner, pipeline.Coal gas drainage pipeline 7 causes water seal for coal gas, to guarantee that reliably blocking coal gas leaks, has guaranteed gas-fired stability, has avoided the de-fire of gas-fired, interrupted Ignition Phenomena.Consider that northern area winter severe cold coal gas drainage pipeline freezes, the coal gas drainage pipe causes water seal for coal gas, can be incubated the coal gas drainage pipeline.
Referring to Fig. 1, in the blow-off pipe of prior art, gas riser 4 one sides set gradually three layers of gas-fired arm 3 from the top down, secondary gas-fired arm 2, one deck burning arm 1, a pipe sewage draining passage is set in the lower end of gas riser 4, be unfavorable for like this blowdown, easily cause the obstruction of blow-off line and valve, affect unstability and the security of boiler coal gas burning.With respect to the blow-off line of prior art, the utility model arranges a blow-off line and a drainage pipeline, and draining and blowdown are smooth, have guaranteed stability and the security of gas boiler.
