Abstract
The invention discloses a high pressure on-line combustion and filtration device for coal-water slurry. The device comprises an upper head, a barrel and a lower head, wherein the upper head and the lower head are respectively connected with the upper end and the lower end of the barrel through a flange, the upper head is provided with a feed inlet, the barrel is connected with a discharge outlet, the bottom of the lower head is provided with a slag outlet, a cylindrical screen mesh is arranged in the barrel, a shaft is arranged at the center of the barrel and is connected with a speed reducer located at the top of the upper head through a shaft coupling, the speed reducer is connected with a motor, a plurality of scraping brushes are vertically arranged and fixed on the shaft through connection structures, and the brushing hairs of the scraping brushes contact with the screen mesh. A high pressure pump delivers coal-water slurry into the barrel and allows the coal-water slurry to carry out swirling motion in the barrel, and the coal-water slurry flows through the screen mesh to space between the screen mesh and the barrel and then flows into a spray gun from the discharge outlet; filtered flaky matters retain on the screen mesh and are brushed off by the rotating scraping brushes, so the flaky matters fall into the lower head and are discharged from the slag outlet, thereby guaranteeing that on granular or flaky matters in the coal-water slurry block the spray gun of a combustor.
Description
Technical field
The present invention relates to a kind of water-coal-slurry high pressure filter that burns online.
Background technology
The high-pressure combustion of water-coal-slurry is to utilize high-pressure pump that the ejection of water-coal-slurry high pressure is to spray pattern, realize the abundant burning of water-coal-slurry, but water-coal-slurry in general filter process in order to increase work efficiency, what adopt is the screen pack of strip, can filter the particle that degranulation footpath surpasses screen pack width, but still having many boards can pass through, when carrying out high-pressure injection, tablet is known from experience delay by the burner noz(zle) mouth of water-coal-slurry, causes jet hole to block.
Summary of the invention
The present invention relates to a kind of water-coal-slurry high pressure filter that burns online, can before carrying out high-pressure injection, the tablet remaining in water-coal-slurry be filtered out, prevent that gun slot from getting clogged.
For realizing this purpose, the method applied in the present invention is: a kind of water-coal-slurry high pressure filter that burns online, comprise upper cover, cylindrical shell and low head, upper cover and low head are connected to respectively the two ends of cylindrical shell by flange, whole by stent support low head bottom, described cylindrical shell central authorities are provided with an axle, axle connects decelerator and the motor at upper cover top by shaft coupling, in cylindrical shell, around axle, be provided with a circle screen cloth, between screen cloth and axle, be provided with many vertically disposed wipers, wiper is fixedly connected on axle, bristle and the screen cloth of wiper are in contact with one another, upper cover is provided with a feeding mouth, upper cover top is provided with rinse mouth, rupture disk connector and Pressure gauge connector, rupture disk connector connects rupture disk, Pressure gauge connector connects a Pressure gauge, cylindrical shell is provided with a discharging opening, low head bottom is provided with a slag notch.
Described wiper is arranged and is formed successively by multistage bristle sections, after strip clamp, is connected with axle.
On described screen cloth, the diameter of mesh is 2mm-5mm.
Its beneficial effect is: high-pressure pump is sent into water-coal-slurry cylindrical shell and in cylindrical shell, formed swirling motion; water-coal-slurry flows into the space between screen cloth and cylindrical shell and flows into spray gun from discharging opening through screen cloth; the tablet being filtered is on screen cloth; by rotating wiper by under tablet brush; it is dropped in low head; through slag notch, discharge; guaranteed not have in water-coal-slurry particle or tablet to block burner gun, due to the effect of high pressure make burner nozzle atomizing effect better, improve efficiency of combustion.
