Description
Technical field
The invention belongs to field of environment protection equipment, particularly relate to Industrial Boiler ash conveying device.
Background technology
At present, environmental pollution is day by day serious, also more and more higher to environmental requirement, meanwhile, also has strict requirement to pulverized-coal fired boiler fume emission.The flue gas that boiler combustion produces is by producing dry ash after bag-type dust, and these dry ashes need to carry out enclosed conveying.Traditional mode of movement comprises storehouse transport pump or compressed air delivery.For storehouse transport pump, investment is large, and equipment is installed complicated, and maintenance cost is high; For compressed air delivery, need a large amount of compressed air, increase the initial cost of air compressor machine, its pressure also can affect the negative pressure of air and gas system.These mode of movements are all successional, but due to combustion of industrial boiler produce flying dust fewer, the dry ash fallen after bag-type dust is few, if continus convergence, cause equipment to dally, flog a dead horse, and this continuous defeated grey mode energy consumption is high, operating cost is high.
Summary of the invention
In order to solve the problem, the invention provides a kind of simple and practical, easy to operate, New-type boiler ash conveying device that cost is low.
According to an aspect of the present invention, a kind of New-type boiler ash conveying device is provided, comprise electronic discharge valve, described electronic discharge valve upper end is connected with surge bunker by pipeline, described electronic discharge valve is connect hours relay A also, described electronic discharge valve lower end is connected with ash tube road, and described ash tube road place is provided with high pressure positive blower, and described high pressure positive blower is connected with time relay B.This device does not need Charge level measurer and control system, only need the simple time relay, at utmost save cost, time setting is carried out according to boiler design technique and experience, regularly unload ash, when dry ash runs up to a certain degree, automatically open electronic discharge valve, then start high pressure positive blower, timing blows.For Industrial Boiler, general fed distance is all closer, and high pressure positive blower can meet completely.After this mode is implemented, energy consumption is very low, and does not need consumption of compressed air.Its beneficial effect is: this appliance arrangement is simple, does not need complicated checkout gear and control program, small investment, easy to maintenance, can reach the object of energy-conserving and environment-protective, and not need continuous running; Achieve airtight conveying, inorganization dust.
In some embodiments, described ash tube road is connected with ash conveying pipe by flow guiding bend pipe, and described ash conveying pipe is arranged in venturi shape.Its beneficial effect is: prevent wind from entering air and gas system in sack cleaner, ash tube road and ash conveying pipe skewed crossing at an angle and the negative pressure produced due to venturi shape can directly ash be drawn through, and can not high-pressure blast toward blowing up, avoid impact to fall grey effect.
In some embodiments, abrasionproof baffle plate is fixed with in the middle of described ash conveying pipe.Its beneficial effect is: prevent the high-pressure blast containing ash from impacting ash conveying pipe.
In some embodiments, maintenance plate is also provided with in the middle of described electronic discharge valve and surge bunker.Its beneficial effect is: convenient maintenance in time when breaking down.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-surge bunker, the electronic discharge valve of 2-, 3-time relay A, 4-high pressure positive blower, 5-time relay B, 6-overhaul plate, 7-ash tube road, 8-ash conveying pipe, 9-flow guiding bend pipe, 10-abrasionproof baffle plate.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the present invention is further illustrated.Accompanying drawing 1 schematically shows New-type boiler ash conveying device of the present invention, comprise electronic discharge valve 2, described electronic discharge valve 2 upper end is connected with surge bunker 1 by pipeline, described electronic discharge valve 2 is connect hours relay A3 also, described electronic discharge valve 2 lower end is connected with ash tube road 7, described ash tube road 7 place is provided with high pressure positive blower 4, and described high pressure positive blower 4 is connected with time relay B5.According to concrete operating condition design and experience setting-up time relay A3 and time relay B5, time opening high pressure positive blower 4 and electronic discharge valve 2, and the time relay B5 of high pressure positive blower 4 will action before electronic discharge valve 2 is opened.When after the ash accumulation certain hour that falls in surge bunker 1, the time relay B5 having preset parameter works, high pressure positive blower 4 operates, after interval a few second, time relay A3 works, and opens electronic discharge valve 2, and dry ash is carried by high pressure positive blower 4 under the drainage in ash tube road 7, close after being delivered to certain hour, wait next stage to circulate.
Air and gas system in sack cleaner is entered for preventing wind, described ash tube road 7 is connected with ash conveying pipe 8 by flow guiding bend pipe 9, described ash conveying pipe 8 arranges in venturi shape, such ash conveying pipe 8 is made venturi shape and is increased flow guiding bend pipe 9, ash tube road 7 and ash conveying pipe 8 skewed crossing are at an angle, and the negative pressure produced due to venturi shape directly can be drawn through ash, and can not high-pressure blast toward blowing up, impact be avoided to fall grey effect.
For preventing the high-pressure blast containing ash from impacting ash conveying pipe 8, in the middle of described ash conveying pipe 8, is fixed with abrasionproof baffle plate 10, to the ash fallen with blow over the high-pressure blast come and guide further.
In order to when ensureing work, equipment breaks down and can safeguard in time and overhaul, in the middle of described electronic discharge valve 2 and surge bunker 1, be also provided with maintenance plate 6.
Above-described is only some embodiments of the present invention, it should be pointed out that for the person of ordinary skill of the art, and under the prerequisite not departing from creation design of the present invention, can also make other distortion and improve, these all belong to protection scope of the present invention.
