Abstract
The utility model discloses a high-pressure online combustion filter of a coal water slurry. The combustion filter comprises an upper sealing head, a barrel body and a lower sealing head, wherein the upper sealing head and the lower sealing head are respectively connected at the upper end and the lower end of the barrel body through flanges; a feed port is connected to the upper sealing head; a discharge port is connected to the barrel body; a slag outlet is formed in the bottom of the lower sealing head; a barrel-shaped sieving screen is arranged in the barrel body; a shaft is arranged at the center of the barrel body and is connected with a speed reducer at the top of the upper sealing head through a shaft coupler; the speed reducer is connected with a motor; a plurality of scraping brushes are vertically arranged and fixed on the shaft through a connecting structure; and the brush bristles of the scraping brushes are in contact with the sieving screen. The coal water slurry is sent into the barrel body through a high-pressure pump and performs vortex motions in the barrel body; then the coal water slurry flows into a space between the sieving screen and the barrel body through the sieve screen and flows into a spraying gun from the discharge port while the filtered sheety materials remain on the sieving screen; and the sheety materials can be brushed off by rotating the scraping brushes so as to fall into the lower sealing head to be discharged from the slag outlet. Thus, the granules or the sheety materials are prevented from existing in the coal water slurry, namely, the blocking of the spraying gun is avoided.
Description
Technical field
The utility model 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.
Utility model content
The utility model 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, and prevents that gun slot from getting clogged.
For realizing this purpose, the method that the utility model adopts 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.
