Background technology
At present, in chemical industry, field of boilers, powder conveying is very general process, and wherein the vertical transport of powder is modal process.In general, carries in order to save energy along the powder of gravitational field, be all dependence gravity carry out powder freely decline carry.Powder load transfer device along gravitational field comprises at least one broach hopper, and this broach hopper comprises top material loading section and bottom blanking section.Although the outlet size of blanking section, much larger than the particle diameter of powder, still likely forms and builds bridge in the time of the discharge downwards of powder material entirety.This obstruction can cause the fault of load transfer device, and then has influence on the fault of whole system.The major cause resulting in blockage is such as having friction force between powder and equipment inner wall, has friction force etc. between powder.In order to prevent latch up phenomenon, corresponding anti-block apparatus must be set in load transfer device.
For many years, in order to solve blockage problem, developed vibration or beaten the methods such as inwall, rotation scraping inwall, gas injection inwall.200810140442.0 proposed the equipment of rotary conic hopper stationary blade, 201020262144.1 proposed the equipment of the fixing broach hopper of rotating blade, although these two kinds of equipment can reach the effect that prevents obstruction, but it is all higher that it prevents stopping up the energy consumption needing, still need a kind of powder load transfer device that prevents efficiently obstruction.
Summary of the invention
Blockage problem while conveying in order to solve powder material, the design people provides a kind of powder load transfer device and method with choke preventing function.
Powder load transfer device proposed by the invention, it comprises at least one broach hopper, this broach hopper comprises top material loading section and bottom blanking section, in bottom, blanking section has spraying equipment and blade, wherein spraying equipment is below blade, the nozzle of spraying equipment is subordinate's section of expecting inwall jet gas down, and blade is connected with S. A., rotates by S. A..
Wherein, spraying equipment is connected with S. A., and S. A. is hollow, for spraying equipment provides jet gas.
Wherein, upwards jet gas of the nozzle of spraying equipment.
Wherein, blade has the nozzle of subordinate's section of expecting inwall jet gas down.
Wherein, the nozzle Jet with downward flow direction gas on blade.
Wherein, blade plan form can be in the shape of a spiral, straight tabular or swash plate shape.
Wherein, there is flow measurement at the outlet section of bottom blanking section.
The flow measuring when flow measurement drops to when a certain amount of, starts anti-blocking equipment, can only start spraying equipment, only start blade, also can start spraying equipment and blade simultaneously; In the time starting blade, the nozzle that can start blade also can not start the nozzle of blade.
The condition of startup is set according to the character of powder material, in general in the time that flow drops to the 80%-40% of normal discharge, starts anti-blocking equipment, reduction energy consumption that can maximal efficiency.Carry for power plant boiler fine coal, in general drop to 70% time startup of normal discharge when flow; And for the fly ash carry of flying dust treating system, in general when flow drop to normal discharge 50% time start.
This equipment is by two kinds of anti-block apparatus of nozzle and blade are set simultaneously, according to actual conditions select to start the two one of or start simultaneously, improved anti-blocking efficiency, reduced energy consumption.Judge stopping state by discharge measurement, select start anti-block apparatus suitable opportunity, improved anti-blocking efficiency, reduced energy consumption.Nozzle is set on blade, in rotation, sprays, improved anti-blocking efficiency, reduced energy consumption.
Accompanying drawing explanation
Fig. 1 represents the structural representation of this equipment.
The specific embodiment
This equipment is referring to Fig. 1.Its structure comprises: at least one broach hopper, this broach hopper comprises top material loading section 1 and bottom blanking section 2, there is spraying equipment 5 and blade 4 in bottom blanking section 2, wherein spraying equipment 5 is below blade 4, the nozzle of spraying equipment 5 is subordinate's section of expecting inwall jet gas down, blade 4 is connected with S. A. 3, rotates by S. A..Spraying equipment 5 is connected with S. A. 3, and S. A. 3 is hollow, for spraying equipment provides jet gas.Upwards jet gas of the nozzle of spraying equipment.Blade has the nozzle of subordinate's section of expecting inwall jet gas down.Nozzle Jet with downward flow direction gas on blade.Outlet section in bottom blanking section has flow measurement 6, and blade plan form is swash plate shape.
In the time of conveying powder material, flow measurement 6 measuring flows change, and when flow drops to when a certain amount of, start anti-block apparatus, can only start spraying equipment 5, only start blade 4, also can start spraying equipment 5 and blade 4 simultaneously; In the time starting blade 4, the nozzle that can start blade 4 also can not start the nozzle of blade 4, thereby prevents that efficiently powder material from stopping up.
Comparative example 1:
Structure and this equipment are similar, just there is no spraying equipment 5, take fine coal as example, when flow drop to normal discharge 70% time start blade (not starting the nozzle of blade), measuring flow returns to 95% energy consumption of normal discharge.
Comparative example 2:
Structure is identical with comparative example 1, take fine coal as example, when flow drop to normal discharge 70% time start blade and (start the nozzle of blade, the nozzle Jet with downward flow direction gas on blade simultaneously, 75 ° of nozzle and horizontal sextant angles), measuring flow returns to 95% energy consumption of normal discharge.
Comparative example 3:
Structure and this equipment are similar, just there is no blade 4, upwards jet gas of the nozzle of spraying equipment, 35 ° of nozzle and horizontal sextant angles, take fine coal as example, when flow drop to normal discharge 70% time start spraying equipment 5, measuring flow returns to 95% energy consumption of normal discharge.
