Description
Technical field
The present invention relates to a kind of dregs breaking device, and in particular to a kind of dregs breaking device for slag gasification furnace bottom.
Background technology
Coal Gasification Technology is the clean coal technology of high-efficiency cleaning.Current Coal Gasification Technology be broadly divided into moving bed gasification,
Fluidized gasification, entrained flow gasification and the class of molten bath gasifica tion four.Wherein, entrained flow bed gasification technology is because its intensity of gasification is high, production
The advantages of ability is big, efficiency of carbon con version is high turns into the main development direction of present Coal Gasification Technology.Entrained flow gasification has two masters
Feature is wanted, one is that running temperature is high, about 1300~1600 DEG C, the lime-ash formed in stove is liquid, and deslagging mode is arranged for liquid
Slag；Another feature is to use " with slag anti-slag " technology to protect furnace wall and reduce heat loss.Airflow bed gasification furnace is often
Occur stifled slag accident, for the shutdown maintenance caused by the stifled slag of gasification furnace, at least need 5 day time, and gasification furnace is used as chemical industry
The beginning of production of enterprise, once parking, causes whole production line all to be stopped transport, whole production line is stopped transport and once causes huge to enterprise
Volume economic loss.For example:A set of gas making amount 80000Nm3/ h coal gasification production line stops transport an economic loss up to 40,000,000 yuan
More than.To sum up, the lower cinder notch of gasification furnace easily blocks up slag in the prior art, causes gasification furnace slag discharge not smooth, and influence gasification furnace is just
Often operation.
The content of the invention
Slag is blocked up the invention aims to the lower cinder notch for solving gasification furnace in the prior art, gasification furnace slag discharge is caused not
Freely, the problem of there is the normal operation of influence gasification furnace, and then a kind of dregs breaking device for slag gasification furnace bottom is provided.
The technical scheme is that：A kind of dregs breaking device for slag gasification furnace bottom include flexible seal device,
Lever, operation handle, support bar, expansion link, flow control valve, feed pipe and water pump, support bar are vertically-mounted on the ground, thick stick
The top of bar and support bar is rotatably connected, and the head end of lever passes through gasification furnace body and extend into the down-comer of gasification furnace bottom
It is interior, it is tightly connected between lever and gasification furnace body by flexible seal device, the end of lever is provided with operation handle, lever

The top of water pipe is provided with expansion link and flow control valve, and the end of feed pipe is connected with water pump.
The present invention has the following effects that compared with prior art：
1st, the present invention solves the problem of airflow bed gasification furnace blocks up slag.There is the reason for lower cinder notch blocks up slag in airflow bed gasification furnace
Have a variety of, mainly have：Gasifier operation temperature is relatively low, and the mobility of slag will be deteriorated, under taper at cinder notch will it is more long-pending more
It is many, cause lower cinder notch valid circulation area to reduce；Gasifier operation is unstable to cause oxygen coal ratio, furnace temperature fluctuation larger, influences slag
Mobility；The coal viscosity-temperature characteristics of ature of coal difference are high, and lime-ash flowing is slow；Slag is carried out without raising furnace temperature before gasification furnace parking,
Causing a large amount of lime-ash to be set at cinder notch reduces cinder notch, and when driving next time, furnace temperature rise is very fast, causes a large amount of slags
Rapidly flowing to lower cinder notch causes lower cinder notch to occur stifled slag.In the present invention using Dao Zhatou centers supply water by the way of disintegrating slag, work as penetrating
When cooling water in down-comer is contacted with high temperature clinker, chemically reacted with the carbon residue in semi-molten clinker, generation one is aoxidized
Carbon and hydrogen, the gas of generation is by clinker spalling.Meanwhile, the clinker surface of semi-molten is cooled down by cooling water, temperature reduction, and
Inside still keeps very high temperature, and clinker is inside and outside to be generated very high internal stress by action of thermal difference, makees in internal stress
Under, clinker fragmentation.Both the above disintegrating slag mode collective effect, small clinker is broken into by big clinker, and is dropped into slag bath.It is right
Sticked in other and the clinker of slag bath is not fallen within wall, operating personnel can make lever in support bar with depression handle
Up under supporting role, in lever interruption insertion down-comer, slag operation is smash in progress.After being repeated several times, dross is crushed at lower cinder notch,
Drop into slag bath, down-comer circulation area increase, deslagging is smooth.It can be seen that apparatus of the present invention solve the problems, such as stifled slag.
2nd, the present invention can intuitively observe rapidly stifled slag situation.In the prior art, indirect means judgement is generally relied on
The whether stifled slag of gasification furnace, such as (1) pressure monitoring when finding gasification furnace pressure and the rise of slag bath internal pressure differences, then judges slag
Mouth may block up slag；(2) bed drain purge in the monitoring gasification furnace unit interval, when the discovery dragveyer quantity of slag pulled out interior for a period of time subtracts
It is small, then judge that cinder notch may block up slag.It can be seen that prior art can not be monitored directly, easily when manometer breaks down, occur
Misjudgement；And response lag, blocks up slag situation serious all the more.After the present invention, gas is directly monitored by industrial water-proof CCD camera
Change the flame intensity under stove at cinder notch and fall slag situation, it is dimmed when detecting flame, when lower cinder notch falls quantity of slag reduction, then illustrate gas
Change cinder notch deslagging under furnace bottom not smooth.It can be seen that personnel monitoring of the present invention is convenient, standard can be made according to monitoring result rapidly
Really judge.
3rd, the present invention is easy to operate, and security is good.In the prior art, because gasification furnace lower cone section does not have any adjusting means,
Therefore temperature at cinder notch can not directly be adjusted.Operating personnel are judged after stifled slag, and excessive oxygen can only be sprayed into by overhead burner
Gas, releases substantial amounts of heat after oxygen and coal dust or syngas combustion, improves the overall temperature of burner hearth, is flowed not at cinder notch
After smooth slag temperature rises with burner hearth bulk temperature, viscosity reduces, and flowing accelerates, and makes cinder notch flowing unobstructed, solves stifled slag and asks
Topic.But during regulation, because combustion heat release region is located at upper of furnace body, the slag blanket of upper inside wall face covering is easily due to height
Warm and thinned even disappearance, loses so that after the salvo of slag anti-slag, scaling loss occurs soon for internal face, ultimately results in blowing out,
Brought about great losses to enterprise.It can be seen that, prior art blocks up slag post processing inconvenience, and risk is larger.And in the present invention, once it is industrial
Camera observes that lower cinder notch flame is dimmed, falls quantity of slag reduction, then may determine that at once and block up slag for lower cinder notch.Staff pushes
Operation handle, makes lever up under the supporting role of support bar, and in lever interruption insertion down-comer, slag operation is smash in progress.Instead
After answering several times, big clinker is crushed at lower cinder notch, and circulation area increase, deslagging is smooth, and stifled slag problem is resolved.It can be seen that the present invention
Easy to operate, security is good.
4th, Suitability of Coals of the present invention is strong.The arrangement of single branch overhead burner of the prior art so that gasifying agent with
Coal dust rapid mixing after entering in stove, after rapidly being heated up through furnace high-temperature gas radiation, occurs rapidly burning anti-in upper furnace
Should, carbon dioxide is generated, amount of heat is released, upper furnace high-temperature region is formed；In burner hearth, bottom then occur carbon residue in slag
With the reduction reaction of carbon dioxide, vapor, reduction reaction strong endothermic, final burner hearth shows what is gradually reduced from up to down
Temperature Distribution.Bottom temperature is low, and molten slag viscosity increase, flowing is not smooth, and smooth deslagging is difficult at furnace bottom lower cone section cinder notch,
Particularly with high-ash-fusion coal, prior art is difficult to handle.After the present invention, it can be operated by manually at interval of certain time
Handle is pushed, cinder notch is turned on this, therefore the present invention can handle the coal of high ash melting point, strengthen gasification furnace Suitability of Coals,
Greatly improve the profitability of enterprise.
