Description
Technical field
Between machine supplying powder of the present invention and burner, separator is set, relates to boiler technology field; In particular to Utility Boiler Technology field; Be specifically related between machine supplying powder and burner, arrange separator technical field.
Background technology
In the igniting, combustion process of station boiler, in order to improve the stability of catching fire, burning of coal, usually take to arrange light-dark separation device at burner body to coal burner, namely upper and lower vertical strong/weak separator or horizontal bias separator is adopted in the position of burner nozzle, the WR burner of such as U.S.'s combustion enginnering company designs, the flame stabilization boat form DC burner of Tsing-Hua University's development and Horizontal Dense dilute Pulverized Coal Burners etc.
For the above-mentioned practice such as arranging light-dark separation device (arranging light-dark separation device, pressure equaliser at burner body) at burner body, its light-dark separation device all must be arranged on the position of burner body, because the light-dark separation device be subject to the restriction of the finite volume of burner apparatus own, arranging in the too short distance of burner length, the wind speed deviation that just inevitably result in the spout ejection of burner deep or light both sides is excessive, igniting and combustion instability and burn insufficient, safety coefficient is low.
For this reason, based on the professional knowledge inside information of inventor with practical experience abundant for many years and to the excelsior unremitting pursue of cause, conscientiously and fully investigating, understand, analyze, research, sum up on above-mentioned existing known technology and present situation basis, take " coal dust classifier is set " key technology, succeed in developing " between machine supplying powder and burner, separator is set " special equipment, in particular, the present invention is succeeding in developing independently on " coal dust classifier " basis exactly, change the existing known technology and present situation that light-dark separation device are arranged on burner body position, but independently coal dust classifier is set between machine supplying powder and burner.Coal dust classifier is exactly " pulverized coal particle separator ", large pulverized coal particle and little pulverized coal particle separate by it, large pulverized coal particle is transported to thick coal culm pipe, little pulverized coal particle is transported to thin powdered coal pipe, the pulverized coal particle that pulverized coal particle in thick coal culm pipe is referred to as in " dense ", thin powdered coal pipe is usually referred to as " light " usually, and this just serves the effect of air-coal separating.It should be noted that: " coal dust classifier " in the present invention and the light-dark separation device being usually used to claim, no matter all do not stand comparison structure or from action and function, usually the used light-dark separation device claimed is arranged on the position of burner body and the two is integrally formed, " coal dust classifier " in the present invention is an independently equipment, and " coal dust classifier " in the present invention can say it is the technological progress of step evolution compared with the usual used light-dark separation device claimed.
" coal dust classifier " that can be independent in the present invention, can be as the case may be, be arranged on any position that between machine supplying powder outlet and burner inlet, First air is suitable, this just constitutes the present invention's this special equipment that " arranges separator between machine supplying powder and burner ", between machine supplying powder and burner, there is enough length, the good mounting condition of independent " coal dust classifier " can be met, by the present invention, thick coal culm air-flow and thin powdered coal air-flow are sent into dense respectively, light burner nozzle, solve dense, the deviation of light burner nozzle breeze airflow speed, solve the deficiency of existing known technology and present situation existence, defect and drawback, , there is not the bad conditions of work such as high temperature and working environment, be conducive to installing and using, be conducive to maintaining and maintenance, be more conducive to and the convenient timely adjustment to deep or light situation in the installation site of independence of the present invention " coal dust classifier ".
Summary of the invention
Key technology that the present invention takes " being provided with coal dust classifier ", its mixing tube is fixedly connected with thick coal culm pipe and thin powdered coal Guan Jun with separator tube, separator tube, and separator tube is connected to rotate the mode be connected of living with regulating shaft, and regulating shaft is fixedly connected with separating plate; The interlude of its Pulverized Coal Bin, coal pipe, machine supplying powder, carrier pipe, middle tube is fixedly connected sequentially, mixing tube on the left end of air hose, middle tube and right-hand member, tube connector, separator is fixedly connected sequentially, and the thin powdered coal pipe port of export on the entrance point of the thick coal culm pipe port of export on separator and dense burner nozzle, separator is all fixedly connected with the entrance point of light burner nozzle.
The object reached by the present invention is: 1., the present invention take " coal dust classifier is set, key technology, provides " arranging separator between machine supplying powder and burner " special equipment.2., the present invention changes the situation always taking light-dark separation device to be arranged on burner body position, overcome at burner finite volume and length too short interior light-dark separation device is set and cause that the wind speed deviation of burner deep or light both sides spout ejection is excessive, igniting and combustion instability and insufficient, many defects and the drawback such as safety coefficient is low of burning.3., the present invention can be as the case may be, will independently " coal dust classifier " be arranged on the suitable any position of First air between machine supplying powder outlet with burner inlet, between machine supplying powder and burner, there is enough length, the good mounting condition of independence " coal dust classifier " can be met, by the present invention, thick coal culm air-flow and thin powdered coal air-flow are sent into dense, light burner nozzle respectively, solve the deviation of dense, light burner nozzle breeze airflow speed, solve the deficiency of existing known technology and present situation existence, defect and drawback; The present invention installs the position of independence " coal dust classifier ", there is not the bad conditions of work such as high temperature and bad working environment, is conducive to installing and using, is conducive to maintaining and maintenance, is more conducive to and the convenient timely adjustment to deep or light situation.4., of the present invention to install and use environment excellent, long service life.5., position each other both thick coal culm pipe of the present invention and thin powdered coal pipe be select position to be therebetween separated from each other, position therebetween mutually side by side in one, provide the coal dust classifier of two types (or model), can select as the case may be, add the leeway of selection.Owing to the invention provides the coal dust classifier of two types (or model), corresponding then provides between the machine supplying powder of two types (or model) and burner arranges separator.6., between machine supplying powder provided by the invention and burner separator is set, can be applicable to various power station, can wide popularization and application, its applied range.7., unique novel, the design science of design of the present invention rationally, simple and ingenious structure, conveniently to make and cost is low, effect stability reliable, run smooth and easy manageability.8., the invention solves the deficiency of existing known technology and present situation existence, defect and drawback.9., of the present inventionly to succeed in developing, effectively raise the technical merit of the industry.
For achieving the above object, technical scheme provided by the invention is:
