Abstract
An ash plug cutting valve mounted in a fly ash conveying pipeline belongs to the field of conveying devices for conveying fly ash generated by the electric precipitation of flue gas in a heat-engine plant. The prior fly ash conveying pipeline has the disadvantages of easy blockage and high running cost. The ash plug cutting valve comprises the pipeline, and a valve body connected with the pipeline, wherein, the valve body comprises a ring plate, a pore plate and an air inlet pipe; the air inlet pipe is connected with the ring plate; the pore plate positioned in the ring plate is connected with the ring plate; an annular groove and more than two vent holes are formed on the pore plate; the air inlet pipe is communicated with a valve inner cavity through the annular groove and the vent holes; the valve inner cavity is communicated with the pipeline; the annular groove is in the shape of a triangle along the radial section of the pore plate; one side of the triangle overlaps the inner wall of the ring plate; and the vent holes are perpendicular to another side of the triangle. The utility model is used for conveying fly ash. Because the plug cutting technology and the dense-phase positive-pressure plug flow pneumatic conveyance technology are adopted, the pipeline avoids being blocked by the fly ash and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to that thermal power plant carries out electric precipitation to flue gas and load transfer device that the fly ash that produces is carried, particularly relates to a kind of grey bolt cutting valve that is installed in the fly ash pipe.
Background technology
Thermal power plant is carrying out collecting a large amount of fly ash by electric precipitation in the process of electric precipitation to flue gas, fly ash is transported to grey storehouse or ash field by collecting ash bucket, relates to delivery duct and mode of movement.The ash transfer mode of prior art mainly contains conveying of concentrated phase malleation strength and the conveying of negative pressure strength etc., and concentrated phase malleation strength is carried by Air compressor and provided conveying to use gas, and air pressure is higher, is generally 5～7kgf/cm
2, this mode of movement, its floating velocity are difficult to control, thereby easy blocking pipe, and the operating cost height; The negative pressure strength is carried by the negative-pressure air fan suction, forms negative pressure, and delivery pressure is slightly less than bar pressure, this mode of movement, and its degree of vacuum is difficult to guarantee, and the operating cost height.Above-mentioned two kinds of ash transfer modes all do not design grey bolt cutting valve in fly ash pipe.
The utility model content
Technical problem to be solved in the utility model is, overcome the high disadvantage of easy blocking pipe, operating cost of the ash transfer existence of prior art, a kind of grey bolt cutting valve that is installed in the fly ash pipe is provided, bolt technology and the close bolt of malleation mutually gas power conveying technology are cut in employing, avoid pipeline to be stopped up, reduce production costs by fly ash.
The technical scheme that its technical matters that solves the utility model adopts is: be installed in the grey bolt cutting valve in the fly ash pipe, comprise pipeline, it is characterized in that: also comprise and plumbing connection valve body together, described valve body is made up of ring flat-plate, orifice plate and air inlet pipe, air inlet pipe and ring flat-plate link together, the orifice plate and the ring flat-plate that are positioned at ring flat-plate link together, design has a circular groove and plural air extractor vent on orifice plate, air inlet pipe communicates with valve insertion through circular groove and air extractor vent, and valve insertion communicates with pipeline.
Described circular groove is triangular in shape along orifice plate section radially, and a leg-of-mutton limit overlaps with the ring flat-plate inwall, and another limit of air extractor vent and triangle is vertical.
The beneficial effects of the utility model are: because this ash bolt cutting valve also comprises and plumbing connection valve body together, described valve body is by ring flat-plate, orifice plate and air inlet pipe are formed, air inlet pipe and ring flat-plate link together, the orifice plate and the ring flat-plate that are positioned at ring flat-plate link together, design has a circular groove and plural air extractor vent on orifice plate, air inlet pipe communicates with valve insertion through circular groove and air extractor vent, valve insertion communicates with pipeline, described circular groove is triangular in shape along orifice plate section radially, a leg-of-mutton limit overlaps with the ring flat-plate inwall, another limit of air extractor vent and triangle is vertical, air inlet pipe links to each other with compressed air system, in fly ash pipe, form the pulsed aeroembolism, make the fly ash in the delivery duct form grey bolt, aeroembolism impels grey bolt to move in delivery duct, thereby avoids pipeline to be stopped up by fly ash, reduces energy consumption and production costs.
