Referring to fig. 2, the diameter of the nozzle 11 is 2mm, the length of the nozzle 11 is 40mm, and the nozzle orifice of the nozzle is 11A in fig. 2.
The utility model provides a gasifier double flange level gauge normality washing unit, its theory of operation is:
(1) the lower liquid phase of the gasification furnace is communicated with the lower part of the balance cylinder 2 through a lower gasification furnace side communication pipeline 3, a liquid level meter liquid phase stop valve 4 and a lower balance cylinder side communication pipeline 5 in sequence; the upper gas phase of the gasification furnace is communicated with the upper part of the balance cylinder 2 through an upper gasification furnace side communication pipeline 6, a liquid level meter gas phase stop valve 7 and an upper balance cylinder side communication pipeline 8 in sequence;
therefore, the gasification furnace 1 and the balance cylinder 2 form a communicating structure, the liquid level of the balance cylinder 2 is equal to that of the gasification furnace 1, and the liquid level of the gasification furnace 1 can be obtained only by measuring the liquid level of the balance cylinder 2.
The upper end and the lower end of the on-site liquid level meter are respectively connected and assembled with the balance cylinder 2 through a first upper flange 12 and a first lower flange 13, so that the on-site liquid level of the balance cylinder 2 is measured through the on-site liquid level meter. The upper end and the lower end of the remote liquid level meter are respectively connected and assembled with the balance cylinder 2 through a second upper flange 14 and a second lower flange 15, so that the liquid level of the balance cylinder 2 is measured and remotely transmitted through the remote liquid level meter.
(2) The inventor finds out through research that the device for realizing the communication between the liquid phase of the gasification furnace 1 and the equilibrium cylinder 2 is as follows: the lower gasifier side communicating pipe 3, the level gauge liquid phase stop valve 4 and the lower balance cylinder side communicating pipe 5 are not easy to block, so that the lower gasifier side communicating pipe 3, the level gauge liquid phase stop valve 4 and the lower balance cylinder side communicating pipe 5 are not required to be additionally processed.
For the device for realizing the communication between the gas phase of the gasification furnace 1 and the balance cylinder 2, namely: go up gasifier side communicating pipe 6, level gauge gas phase stop valve 7 and last balance cylinder side communicating pipe 8, because contain a large amount of buggy in the gas phase, consequently, the buggy very easily leads to last gasifier side communicating pipe 6, level gauge gas phase stop valve 7 and last balance cylinder side communicating pipe 8 to block up, and when last gasifier side communicating pipe 6, level gauge gas phase stop valve 7 and last balance cylinder side communicating pipe 8 block up, can destroy gasifier 1 and balance cylinder 2 connectivity, lead to the liquid level of balance cylinder 2 can not truly represent the liquid level of gasifier 1, the inaccurate phenomenon of gasifier liquid level measurement instrument instruction also appears.
Therefore, in this application, when gasifier 1 normally works, level gauge gas phase stop valve 7 and level gauge liquid phase stop valve 4 are the open mode this moment, the air current in gasifier 1 passes through level gauge gas phase stop valve 7 and gets into balance cylinder 2, at this in-process, open wash pipe stop valve 10 simultaneously, consequently, outside sparge water is through wash pipe stop valve 10 and 11 blowout sparge waters of shower nozzle, the sparge water sprays to gasifier 1, in the sparge water is to gasifier 1 injection process, can carry the buggy in the gas phase and return inside gasifier 1 together. Therefore, on one hand, the washing water rushes into the gasification furnace 1, and the normal operation of the gasification furnace 1 is not influenced by the washing water because the gasification furnace 1 originally has water; on the other hand, when the flushing water rushes into the gasification furnace 1, the air flow is filtered, so that the pulverized coal in the air flow can be effectively flushed back into the gasification furnace 1, the gasification furnace side communication pipeline 6, the liquid level meter gas phase stop valve 7 and the upper balance cylinder side communication pipeline 8 are prevented from being plugged by the pulverized coal, the connectivity of the gasification furnace 1 and the balance cylinder 2 is ensured, and the accuracy of the liquid level measured by the liquid level measuring instrument is further ensured.
In this application, through the water spray end installation shower nozzle 11 at level gauge washing pipe 9, provide effectual range, can effectively guarantee the effectual gasification furnace that flows into of sparge water to guarantee to get in the gasification furnace that pressure port department does not have the scale deposit.
A flushing water pipe stop valve 10 is additionally arranged before a liquid level meter flushing water pipe 9 enters an upper balance cylinder side communication pipeline 8, and flushing is stopped when stopping maintenance is convenient.
Among the traditional mode, gasifier level gauge sparge water is washed in differential pressure transmitter diaphragm capsule department, has certain influence to level measurement when opening the sparge water, measures unstably, and undulant great, in addition, is the mode that adopts intermittent type formula to wash. And in this application, wash the mouth of a river position with the level gauge and set up to level gauge gas phase stop valve 7 and balance cylinder inlet pipeline on, be close to the position of level gauge gas phase stop valve 7 as far as possible, 9 installation requirements of level gauge wash water pipe insert the central line position of last balance cylinder side communicating pipe line 8, guarantee as far as possible that the sparge water flows into the gasifier along the pipeline central line, and can not flow into in the balance cylinder and disturb the measurement of liquid level.
In addition, the normal state washing unit of gasifier double flange level gauge that this application provided is a normal state washing mode, rather than intermittent type formula washing mode. That is, during operation of the gasification furnace, the washing water is continuously injected toward the gasification furnace through the injection head, thereby effectively preventing the upper gasification furnace side communication line 6, the level gauge gas phase cut-off valve 7, and the upper surge tank side communication line 8 from being clogged. In addition, the normal measurement display of the liquid level meter is not influenced during the flushing process.
Consequently, the application provides a gasifier double flange level gauge normality washing unit can effectively solve the unsafe problem of gasifier level measurement, and it is convenient to overhaul on line simultaneously, does not influence the level gauge and shows, has improved monitor's use continuity. In addition, the flushing device can be started to flush under the conditions of starting, stopping, normal operation and accident of the gasification furnace, the accuracy requirement of the measurement of the liquid level meter is met, and the safe and reliable operation of the gasification furnace equipment is ensured.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be viewed as the protection scope of the present invention.
