Abstract
The utility model discloses a coal gasification equipment high pressure coal slurry pump feeding system for gasifier. The coal slurry pump comprises a high-pressure coal slurry pump with two feeding pipelines and inlet buffers which are arranged on the two feeding pipelines and used for buffering the pressure of the coal slurry in the feeding pipelines and the fluctuation of the flow, wherein two discharging pipelines are also arranged on the high-pressure coal slurry pump, discharging buffers used for buffering the coal slurry conveyed in the discharging pipelines are respectively arranged on the two discharging pipelines, and the coal slurry entering the high-pressure coal slurry pump is conveyed from the discharging pipelines after being pressurized and is output after being buffered by the discharging buffers. After adopting above-mentioned structure, reduced coal stuff pump outlet pressure fluctuation by a wide margin, coal stuff flow also tends to stable and start and stop to step up and pressure release in-process pressure and flow are more steady to make coal stuff carry very stably, just also make coal stuff can stably carry to the gasifier in, produce effective gas with the good contact reaction of oxygen, can realize the effective extension of the life of nozzle, excellent in use effect.
Description
Technical Field
The utility model relates to a feeding system of coal gas equipment, specific high-pressure coal slurry pump feeding system for coal gas equipment gasification stove that says so.
Background
In order to overcome the problem, although the plunger pump is provided with a buffer, the pressure and the flow of the coal slurry still fluctuate greatly in the high-load production process, so that the service life of the burner still can be influenced, particularly the large outlet of the high-pressure coal slurry pump can cause the coal slurry flow fluctuation in a coal slurry outlet pipeline to be large, and the large outlet of the coal slurry pump can cause the oxygen-coal ratio fluctuation to be large, so that the possibility of triggering coal slurry flow low-low interlocking or oxygen-coal ratio high-high interlocking can cause the gasifier to stop, and the methanol acetic acid full-line production can be influenced.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a can effectively reduce coal slurry pressure and flow fluctuation to improve coal slurry and carry high-pressure coal slurry pump feeding system for gas plant gasification stove of stability.
In order to solve the technical problem, the utility model discloses a coal gasification equipment is high-pressure slurry pump feeding system for gasifier, including the high-pressure slurry pump that has two feed line and set up the pressure that is arranged in buffering feed line coal slurry on two feed line, the undulant feeding buffer of flow, still be provided with two discharge line that are arranged in carrying the nozzle department of gasifier with the coal slurry on the high-pressure slurry pump, be provided with the ejection of compact buffer that is arranged in buffering discharge line coal slurry on two discharge line respectively, the coal slurry that enters into in the high-pressure slurry pump is carried and is exported after the ejection of compact buffer buffering from discharge line after the pressurization.
The high-pressure coal slurry pump is a double-acting diaphragm plunger pump.
And pressure gauges positioned in front of the discharging buffer are arranged on the discharging pipelines.
And ball valves positioned at the rear of the discharging buffers are arranged on the discharging pipelines.
The two feeding pipelines are of a herringbone structure.
After adopting foretell structure, the coal slurry enters into in the high pressure coal slurry pump and carries and has cushioned the pressure and the flow of coal slurry in the coal slurry pump outlet pipeline after the pressurization through ejection of compact buffer from the discharge tube way, high pressure coal slurry pump outlet pressure fluctuation has been reduced by a wide margin from this, make the coal slurry flow of carrying to the gasifier nozzle also tend to stabilize and start-stop and step up and pressure release in-process pressure and flow more steady, thereby make the coal slurry carry very stably, just also make the coal slurry can stably carry to the gasifier, produce effective gas with the good contact reaction of oxygen, can realize the effective extension of the life of nozzle, excellent in use effect.

Detailed Description
The high-pressure slurry pump feeding system for the gasification furnace of the coal gas equipment of the present invention will be described in further detail with reference to the accompanying drawings and the specific embodiments.
The utility model discloses a coal gas equipment is high-pressure slurry pump feeding system for gasifier, including high-pressure slurry pump 2 that has two feed line 1 and set up the pressure that is arranged in buffering coal slurry groove to the inlet pipe way between the high-pressure slurry pump on two feed line, the undulant feeding buffer 3 of flow, the pump chamber export of high-pressure slurry pump 2 still is provided with two discharge line 4 that are used for carrying the coal slurry to the nozzle department of gasifier, be provided with respectively on two discharge line 4 and be arranged in buffering the coal slurry pressure of carrying in the discharge line and the undulant ejection of compact buffer 5 of flow, can stabilize the pressure and the flow fluctuation of coal slurry in the outlet pipe way through ejection of compact buffer 5 from this, all be provided with the manometer 6 that is located ejection of compact buffer 5 the place ahead on two discharge line 4, still be provided with respectively on two discharge line 4 and be located the ball valve 7 of ejection of compact buffer 5 rear, the coal slurry that enters into in the high-pressure slurry pump 2 is carried from discharge line 4 after the pressurization and is exported after buffering through ejection of compact buffer 5.
Further, the high-pressure coal slurry pump 2 is preferably a double-acting diaphragm plunger pump, and in addition, the two feeding pipelines 1 are of a herringbone structure.
Through verification, adopt the utility model discloses a high-pressure coal stuff pump feeding system for coal gasification equipment gasifier, pressure and flow are undulant generally being less than 0.1MPa and being less than 1m 3 At start and stop, boostAnd pressure and flow fluctuation can not aggravate in the pressure relief process, a resonance area is eliminated, and the aggravation of coal slurry pressure and flow fluctuation is avoided when a high-pressure coal slurry pump breaks down from a buffer, so that the effects of avoiding coal slurry pipeline shaking, prolonging the service life of a burner and prolonging the operation period of a gasification furnace are achieved.
