Abstract
The invention discloses a conveying device in a positive and negative integrated multifunctional pump system, which is characterized in that a pressurizing fluidization pipe is connected with a gas and ash filtering device at the top of a bin pump through a pressurizing pipeline, the pressurizing fluidization pipeline is connected with a fluidization device in the bin pump through a fluidization pipe, a pneumatic discharging valve is positioned below a multifunctional bin pump and connected with a discharging pipeline, the discharging pipeline is connected with a positive pressure ash conveying pipeline through a positive pressure ash conveying pipe feeding point, and a flow regulating device is arranged in front of the feeding point on the positive pressure ash conveying pipeline for controlling the flow of compressed air passing through the feeding point.
Description
Technical field
The present invention relates to feedway in a kind of powder material air-transport system device, the feedway in the agstone strength transport systems device of particularly big-and-middle-sized coal-fired power plant pneumatic ash removal system device, boiler flue gas desulfurization system.
Background technology
Usually adopt top-guiding type storehouse pump or the following load transfer device that draws two kinds of discharge methods of storehouse pump in the strength conveying engineering.Be difficult to control discharging speed owing to draw formula storehouse pump under existing, therefore plugging is easily seldom used in middle and long distance pneumatic ash handling engineering.
Drawing formula storehouse pump down is to rely under the combined action of storehouse pump internal pressure and delivery duct internal pressure differences and dry ash deadweight, and dry ash in the pump of storehouse is sent in the ash conveying pipe.Carrying pressurized air by dry ash in the pump delivery pipeline of storehouse, is a kind of interruption mode of movement, major advantage such as have therefore that the storehouse pumps that material speed is fast, nothing left ash in the pump of storehouse, transport efficiency height, storehouse pump body energy consumption are low, but also have following fatal shortcoming simultaneously.
1, existing drawing formula storehouse pump adopts the silicon carbide porous plate usually down, because the silicon carbide porous plate stops up easily, makes that dry ash can not get abundant fluidization in the pump of storehouse, reduces the dry ash flow property, and dry ash is bridging easily in the pump of storehouse, influences the storehouse and pumps ash.
2, when storehouse pump internal pressure is less than or equal to the ash conveying pipe internal pressure, carried the effect of pressurized air jacking, the storehouse pump is ash discharge not, when storehouse pump internal pressure during greater than the ash pipeline internal pressure, dry ash can be sent in the ash conveying pipe by speed in the pump of storehouse, make and carry pressurized air can't carry dry ash, cause ash conveying pipe to stop up.
3, draw the uncertain factors such as restriction that formula storehouse pump volume and ash conveying pipe caliber are difficult to reasonable disposition and are subjected to down to draw the horizontal ash conveying pipe arrangement length of formula storehouse pump discharge down, draw formula storehouse pump delivery reliability under reducing.
Summary of the invention
The object of the invention provides a kind ofly can control discharging speed, is not easy the feedway of plugging.
For achieving the above object, the present invention adopts following design plan, feedway in a kind of positive-negative integral multifunction pump delivery system, comprise pressurized fluidized pipeline, pressure pipeline, the fluidisation pipeline, fluidizer, pneumatic bleeder valve, discharge pipe, the malleation ash conveying pipe, flow control device is formed, pressurized fluidized pipeline links to each other with Cang Bengding gas ash filtering installation by pressure pipeline, pressurized fluidized pipeline links to each other with fluidizer in the pump of storehouse by the fluidisation pipeline, the below that pneumatic bleeder valve is positioned at multi-functional storehouse pump links to each other with discharge pipe, discharge pipe links to each other with the malleation ash conveying pipe by malleation ash conveying pipe pan feeding point, on the malleation ash conveying pipe, the place ahead at pan feeding point is provided with flow control device, and control is through the compressed air require size of pan feeding point.
Described flow control device is a flow-through orifice.
Advantage of the present invention is:
1, carry pressurized air in the pump of storehouse, not have loss of pressure.
Carried continuously in ash conveying pipe with after carrying pressurized air to be mixed into gas ash compound owing to draw the dry ash of formula storehouse pump output down, carry pressurized air, therefore do not exist and carry the loss of pressure of pressurized air in the pump of storehouse, reduced conveying energy consumption not by the storehouse pump.
2, improve transport efficiency, convey unit gas consumption and unit consumption of energy fall.
Owing to draw down formula storehouse pump delivery pressurized air, do not exist dry ash in the pump of storehouse to be transported to and to carry the second interruption mode of movement that overlaps dry ash in the pump of storehouse behind the grey storehouse by the storehouse pump; A plurality of pan feeding points can be arranged on an ash conveying pipe, adopt and alternately in ash conveying pipe, import dry ash, make ash conveying pipe be in continuous conveying dry ash state, improve and carry compressed air delivery dry ash efficient, reduction convey unit gas consumption and convey unit energy consumption, have obvious energy-saving effect.
3, drawing the formula storehouse under the raising pumps ash, carries reliability.
Draw the formula storehouse under conveying pressurized air current difference calculates before and after the employing ash conveying pipe pan feeding point and pump the material time, the control pan feeding, transportation concentration is to draw smooth ash discharge of formula storehouse pump and dry ash down can evenly mix the back by the important assurance of smooth delivery of power continuously with carrying pressurized air in ash conveying pipe, also is the effective technology measure that prevents that ash conveying pipe from stopping up.
Description of drawings
Fig. 1 is transport conveyor constructions scheme drawing in the positive-negative integral multifunction pump delivery system of the present invention.
The specific embodiment
The structure of feedway as shown in Figure 1 in the positive-negative integral multifunction pump delivery system of the present invention, feedway in a kind of positive-negative integral multifunction pump delivery system, comprise pressurized fluidized pipeline 2, pressure pipeline 3, fluidisation pipeline 4, fluidizer 5, pneumatic bleeder valve 6, discharge pipe 7, malleation ash conveying pipe 1, flow control device 9 is formed, pressurized fluidized pipeline 2 links to each other with Cang Bengding gas ash filtering installation 10 by pressure pipeline 3, pressurized fluidized pipeline 2 links to each other with fluidizer 5 in the pump of storehouse by fluidisation pipeline 4, the below that pneumatic bleeder valve 6 is positioned at multi-functional storehouse pump 11 links to each other with discharge pipe 7, discharge pipe 7 links to each other with malleation ash conveying pipe 1 by malleation ash conveying pipe pan feeding point 8, on malleation ash conveying pipe 1, in the place ahead of pan feeding point 8 flow control device 9 is set, control is through the compressed air require size of pan feeding point.
Described flow control device is a flow-through orifice.
Carry in the pump of storehouse and be equipped with level-sensing device.
Workflow of the present invention is: draw formula storehouse pump supercharging blowback pneumatic valve under opening, draw formula storehouse pump fluidisation pneumatic valve under opening, carry this moment pressurized air by Cang Ding gas ash filtering installation to supercharging in the pump of storehouse, to the filter bag blowback, butterfly type nozzle carries out the fluidization processing to dry ash in the pump of storehouse simultaneously, when the pressure that draws formula storehouse pump instantly reaches preset value,, open the pneumatic bleeder valve of storehouse pump by storehouse pump pressure transmitter output signal.When the material time is pumped when reaching preset value in the storehouse, pump material time controller output signal by the storehouse, the multifunction pump malleation is carried and is finished.
