Description

Anticlogging gasification furnace flowing line system in a kind of Ammonia Production

Technical field

The utility model is related to synthetic ammonia installation technical field, it is specifically related to anticlogging gas in a kind of Ammonia Production Change fire grate water pipeline system.

Background technology

Synthetic ammonia gasification fire grate water generally has three tunnel whereabouts, be respectively be discharged into slag bath, go into operation cooler and hp flash drum. Since synthetic ammonia gasification stove need to undergo draining switching twice to rising to normal production pressure feeding intake：Switch for the first time, gasification Stove is before pressure is raised to 0.5Mpa after feeding intake successfully, and the water of gasification furnace is directly discharged into slag bath, when gasification furnace pressure rises to 0.5Mpa Afterwards, the toxic and harmful gas to avoid high temperature buck and its inside from dissolving impacts environment and personnel, and gasification furnace is drained It cuts toward the cooler that goes into operation and carries out cooling processing；Second of switching, after gasification furnace pressure is raised to 4.0MPa, for recovery system heat Amount reduces solid content, a small amount of sour gas of parsing in Heisui River temperature, concentration Heisui River, it is necessary to the water for being discharged into the cooler that goes into operation It is switched to hp flash drum.

Gasification furnace draining often will appear the problem of not draining when switching for second, thus seriously affect gasification furnace And the normal operation of hp flash drum.Because three sets of gasification furnaces share a set of main sewer in normal production, it is standby to open one two In system, wherein two gasification furnace long-term operations, can make spare gasification furnace drain main valve to this length of tubing of main sewer For interior fluid for a long time in not flow regime, it is total to may result in back-up vaporization fire grate water for the operation once back-up vaporization stove is driven Valve, due to the effect of expanding with heat and contract with cold, causes the dirty piece in pipeline to fall off to the pipeline between main sewer, the dirty piece that falls off and black The fine ash deposited in water is easy in back-up vaporization stove to the flowing line between hp flash drum caking to blocking pipeline, into And back-up vaporization stove is caused to be unable to operate normally.

Invention content

In order to solve the above technical problems, the utility model provides anticlogging gasification furnace draining in a kind of Ammonia Production Pipeline system.

To achieve the above object, the utility model uses following technical scheme：

Anticlogging gasification furnace flowing line system in a kind of Ammonia Production, including gasification furnace A after parking, lead to height The main sewer of flash tank, grey supply mains, the drain header of the gasification furnace A is pressed to be connected with respectively towards first of slag bath Pipe, the second branch pipe towards the cooler that goes into operation and the third branch pipe towards the main sewer, the third branch pipe end are set There are the first control valve, the buck that the third branch pipe end is also associated with positioned at first control valve water inlet front end total Pipe, the ash supply mains lead to second branch pipe when first control valve is closed by the third branch pipe.

Further, the third branch pipe being sequentially arranged along drainage direction is connected on the main sewer, for being in 4th branch pipe of the gasification furnace B drainings of operating status, the 5th branch pipe drained for gasification furnace C in operating status, the ash Supply mains is in charge of by first to be connected to the third branch pipe, and the ash supply mains is in charge of and the main sewer by second Cecum is connected to.

Further, described first is in charge of equipped with the second control valve.

Further, which further includes raw water pipeline, and the raw water pipeline passes through the first feed pipe and first branch pipe Connection, the raw water pipeline are connected to by the second feed pipe with second branch pipe.

Further, first branch pipe, which is equipped with, controls the third control that the drain header is drained to first branch pipe Valve, second branch pipe, which is equipped with, controls the 4th control valve that the drain header is drained to second branch pipe, the third Branch pipe, which is equipped with, controls no the 5th control valve drained to the third branch pipe of the drain header.

Further, first feed pipe, which is equipped with, controls the 6th control that the raw water pipeline supplies water to first branch pipe Valve processed, second feed pipe, which is equipped with, controls the 7th control valve that the raw water pipeline supplies water to second branch pipe.

The advantageous effect of above-mentioned technical proposal is mainly reflected in the following aspects：

(1) during gasification furnace A described in the utility model parking, by the buck in the grey supply mains successively to the Three branch pipes, the second branch pipe carry out back flush, because of the past cooling that goes into operation of drain header when gasification furnace A can be effectively prevent to drive again There is the problem of pipeline blocking when filling draining in device, high pressure flash, it is ensured that gasification furnace A is discharged into the cooler that goes into operation when gasification furnace A drives And the flowing line that high pressure flash fills is unimpeded, ensures that gasification furnace A can be with normal operation.

(2) when be connected on the main sewer third branch pipe being sequentially arranged along drainage direction, for be in fortune 4th branch pipe of the gasification furnace B draining of row state, for gasification furnace C drainings in operating status five branch pipes when, described the Two are in charge of and can be rinsed to the main sewer pipeline section between the third branch pipe and the 4th branch pipe, to further prevent Line clogging.

(3) it when gasification furnace A described in the utility model drives to run, controls second control valve and closes and shuts off flushing ash Water；After gasification furnace A parking, control that first control valve is closed, the second control valve is opened, can to second be in charge of with And third is in charge of and is rinsed operation.The utility model, which can guarantee, to be drained after gasification furnace A operation normal, ensures gasification furnace A not Can cause because of the blocking of flowing line system cannot normal production run, can avoid gasification furnace A, to be forced parking primary, significantly Save gasification furnace driving cost.Meanwhile the utility model it is simple in structure, it is easy to operate, control stablize, equipment used it is few and Simply, input cost is low.

(4) since there are the lime-ash of coal in the draining in gasification furnace A operational process, the raw water pipeline can be in gasification furnace When A drives stable (gasification furnace A is drained to main sewer into hp flash drum by third branch pipe), it is necessary to the One branch pipe and the second branch pipe are rinsed, and are prevented the first branch pipe and the second branch pipe fouling and are led to line clogging.
