Description
Technical field
It is to be related to a kind of shower nozzle for fuel gas pulse ash blower device specifically the present invention relates to a kind of shower nozzle, belongs to boiler plant technical field.
Background technology
In the process of running, back-end surfaces generally produce dust stratification to coal-fired and oil burning boiler, increase flue gas resistance, and exhaust gas temperature is raised, and has a strong impact on the normal operation of boiler.Conventional steam blowing technique is unsuitable for removing boiler tail dust stratification under many circumstances both at home and abroad, and dedusting effect is very undesirable.Main cause is that steam soot blowing can cause the smoke moisture to increase, it is easier to cause dust stratification and blocking, also corrosion can sometimes aggravated, higher to calcium content or sulfur content is grey even more so.
Fuel gas pulse ash blower device is a kind of advanced in performance deashing device of new generation, fuel gas pulse ash blower device utilizes the conventional gaseous fuel such as acetylene or coal gas, natural gas, liquefied petroleum gas, burnt in the combustion chamber of particular design, and shock wave is launched with the nozzle on efferent duct, the dust stratification on heating surface is set to come off by the effect of shock wave, dedusting effect is notable, and stable equipment operation reliability, operation and maintenance are simple, with preferably economy.
But, the shower nozzle of existing fuel gas pulse ash blower device is fixedly disposed at dust stratification, can only blow in one direction, blowing direction is single, active area is smaller, it is impossible to take into account the treatment of wider place's dust, and ash disposal flexibility is poor, still the normal operation of boiler can be to a certain extent influenceed after long-play, it is still necessary to which remove boiler carries out manual deashing to dead angle.Therefore, a kind of simple structure, the shower nozzle of the fuel gas pulse ash blower device that reasonable in design, ash disposal flexibility is good are urgently released.
The content of the invention
In view of the above-mentioned problems existing in the prior art, it is an object of the invention to provide a kind of shower nozzle for fuel gas pulse ash blower device, by the structure of reasonable design sprinkler, solve the problems, such as that shower nozzle blowing direction is single, increase deashing scope, improves the use flexibility of shower nozzle, expands the scope of application.
For achieving the above object, the technical solution adopted by the present invention is as follows：
A kind of shower nozzle for fuel gas pulse ash blower device, including efferent duct, spout, deflector, push rod and controlled motor, wherein, one end of efferent duct and the combustion chamber of fuel gas pulse ash blower device, notch setting efferent duct the other end and be connected with efferent duct, deflector is movably connected in vents face, push rod one end is flexibly connected with deflector, the push rod other end is then arranged on the output shaft of controlled motor, push rod is driven to stretch by controlled motor rotating, so as to control the folding angle of nozzle deflector, multi-angle deashing interior on a large scale is realized.
Preferably, in order to further increase the folding angle of deflector, larger range of deashing is realized, angle shape is set at vents face.
It is highly preferred that being set at vents face horizontal by 45 degree of angle shapes at angle.
It is highly preferred that deflector ovalize tabular, can be brought into close contact with vents face.
It is further preferred that the folding angle of deflector is 0 °~135 °.
Preferably, for the ease of the installation of deflector, manufacture and installation cost are saved, deflector is hinged on vents face.
Preferably, in order to be beneficial to control deflector folding, push rod one end is hinged with deflector.
It is highly preferred that the output shaft of the push rod other end and controlled motor welds, pin joint or is spirally connected.
Preferably, in order to shorten the actuating length of push rod, controlled motor is arranged on the outer wall of efferent duct.
In such scheme, further, controlled motor elects linear electric motors as.
Relative to prior art, the beneficial effects of the invention are as follows：By rationally design and optimization nozzle structure, folding of the deflector in the range of 0 °~135 ° is realized with fairly simple feasible control method, change jet-impingement direction, solve the problems, such as single injection direction, increase deashing scope, the use flexibility of shower nozzle is improve, the input of manpower and materials is substantially reduce the number, economy is splendid.Therefore, with very wide application prospect and promotional value.
Brief description of the drawings
Fig. 1 is a kind of structural representation of shower nozzle for fuel gas pulse ash blower device that the present invention is provided.
Specific embodiment
The present invention is made with preferred embodiment below in conjunction with the accompanying drawings further to illustrate detailed completely.
A kind of preferred embodiment schematic diagram of shower nozzle for fuel gas pulse ash blower device that Fig. 1 is provided for the present invention.As shown in figure 1, the shower nozzle for being used for fuel gas pulse ash blower device includes efferent duct 1, spout 2, deflector 3, push rod 4 and linear electric motors 5, wherein, efferent duct 1 is cylindrical, the top of efferent duct 1 and the combustion chamber of fuel gas pulse ash blower device（Do not shown in figure）Connection,Spout 2 is arranged on the bottom of efferent duct 1 and is connected with inside efferent duct 1,Deflector 3 is hinged on the end face of spout 2,The end of spout 2 is set to horizontal by 45 degree of angle shapes at angle,Accordingly,Deflector 3 is arranged to elliptical plate shape,Deflector 3 can be brought into close contact with the end face of spout 2,One end of push rod 4 is hinged with the middle part of deflector 3,Output shaft of the other end of push rod 4 then with linear electric motors 5 is directly spirally connected,Linear electric motors 5 are fixedly connected on the outer wall of efferent duct 1,Operating personnel are by controlling the rotating of linear electric motors 5 flexible come driving push rod 4,Then the folding in 0 °~135 ° angular ranges of deflector 3 at control spout 2,The i.e. stop motion when deflector 3 reaches the angle of requirement,And proceed by purging,Inflation,The actions such as blast soot blowing,Cleaned out until the place for wishing to process,The injection work of a next position is carried out again,So as to realize the large-scale deashing of multi-angle.
