Abstract
The utility model discloses a barrel of an automatic soot blower, which belongs to a soot blower barrel and comprises a section A and a section B, wherein the section A is an air flow inlet section with an inner hole of the barrel diameter shrinking gradually, and the section B is an air flow outlet section with an inner hole of the barrel diameter expanding gradually. The section A of the soot blower barrel enables air flow below sound speed to be compressed and accelerate to reach the sound speed, and the section B of the soot blower barrel enables air flow above the sound speed to be expanded and accelerate continuously to reach supersonic speed. The barrel of the automatic soot blower has the advantages that an inner cavity of the barrel is designed into the two-section structure with changing diameters, the air flow in the barrel can be accelerated, and impact energy and soot cleaning effects of the air flow can be improved.
Description
Technical field
The utility model relates to a kind of soot blower gun barrel, specifically is a kind of automatic soot blower gun barrel.
Background technology
For the toxic emission part of equipments such as biomass boiler, cement cold prevention machine, bag dust collector, be the high-temperature gas of high dust content owing to what flow in the pipeline, dust deposits on duct wall easily, influences the heat radiation of pipeline and causes chemical attack.For biomass boiler, the stalk owing to acting as a fuel has very special combustion characteristics especially, thereby comparatively outstanding aspect the high temperature corrosion of alkali metal and chlorine initiation.Because contain the potassium of high concentration in the stalk, ash melting point is very low behind the straw burning, and contains the potassium material and separate out easily, again in the burning easily on heating surface deposition generate the dust stratification that is difficult to remove, increase heat transmission resistance and also cause the flue gas flow area to block.Simultaneously chloride deposit has stronger corrosivity to the heating surface metal under hot environment, particularly is being higher than under 500 ℃ the environment, and temperature highly corrosive speed more is fast more.To above-mentioned situation, the automatic soot blower of many employings in cement cold prevention machine, boiler and the bag dust collector, the dust that regularly deposits on the clearing of pipeline wall is with mitigate corrosion.The gas-burning pulse ash-blowing device is the most frequently used soot blower; It is to utilize the combustion gas and the air of high responses abilities such as acetylene, hydrogen, natural gas, liquefied gas and oil plant Device in Gas to prepare by a certain percentage; In special turbulated tube, make it to produce detonation; Burning gases moment pressure energy increases sharply; Detonation flame exports unexpected pressure energy with high speed at directed pulsed fuel gas nozzle and discharges ejection, removes the dust stratification on the boiler heating surface through purging, acoustic fatigue, heat cleaning and local rapping, and last dust is taken away by flue gas stream winding up.The gun barrel passage of this kind soot blower is a straight channel, and air velocity does not change through gun barrel the time, and is when air pressure is low, bad to the cleaning effect of dust stratification.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of automatic soot blower gun barrel, and this gun barrel can accelerate to ultrasonic state with high-temperature gas.
The utility model is realized with following technical scheme: a kind of automatic soot blower gun barrel, and described gun barrel is made up of for two sections A, B, and the A section is the air flow inlet section, and the B section is the air stream outlet section; A section caliber endoporus is contracted to the B section gradually, and B section caliber endoporus is expanded gradually.
The beneficial effect of the utility model is: the inner chamber of gun barrel is designed to the two-part structure of vary in diameter, and air-flow obtains quickening in gun barrel, improves the impact energy and the ash-removal effect of air-flow.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, electromagnetic valve outlet joint, 2, gun barrel, 3, sootblower nozzle.
The specific embodiment
Shown in accompanying drawing, the soot blower gun barrel has a gun barrel 2 automatically, and described gun barrel 2 is made up of for two sections A, B, and promptly the inner chamber of gun barrel is designed to the two-part structure of vary in diameter.The A section is the air flow inlet section, and the B section is the air stream outlet section, and air flow inlet section caliber endoporus shrinks gradually, is retracted to arrive the air stream outlet section behind the certain size, and the caliber endoporus is expanded gradually.The effect of pipeline A section is to make air-flow below velocity of sound, obtain compression, realizes quickening, and reaches velocity of sound; The effect of B section is to make the speed of air-flow more than velocity of sound obtain expansion, realizes continuing to quicken, thereby reaches supersonic speed, improves the impact energy and the ash-removal effect of air-flow.
In the present embodiment, described gun barrel 2 adopts convergent-divergent channel.According to Hydrodynamics Theory, in subsonic speed one dimension isentropic flow in pipe, sectional area reduces, and flow velocity increases, and sectional area increases, and flow velocity reduces; And in gas supersonic speed one dimension constant entropy flowed, sectional area increased, and air-flow quickens, and sectional area reduces, and air-flow slows down.Therefore, for above-mentioned gun barrel fouling, air-flow will obtain quickening in the A section, if the node of appropriate design A, B section lets air-flow reach the velocity of sound at the node place, then air-flow will continue to obtain to quicken in the B section, thereby makes air-flow accelerate to supersonic speed.
The course of work: the A section porch of soot blower gun barrel is connected with the external electric magnet valve through electromagnetic valve outlet joint 1, and B section exit connects sootblower nozzle 3.When magnetic valve was opened, air-flow got into gun barrel A section with certain initial velocity, because the contraction of gun barrel diameter of bore, air-flow obtains quickening, and the place, joint portion to A, B two ends reaches velocity of sound.Then, air-flow gets into the B section of gun barrel, because air velocity has reached velocity of sound; The expansion of B section makes air-flow continue to quicken, thereby reaches supersonic speed, and the gun barrel end links to each other with nozzle; Accelerate to ultrasonic air-flow and spray, impact at a high speed the dust stratification that accumulates on the pipeline wall and dust stratification is blown off from nozzle.
