Description
Technical field
The present invention relates to glasswork technical field of producing, the regenerator glass melter Technology that relates to furnace burning producer gas, relate in particular to the large-scale cross flame thermal storage type glass melting furnaces Technology of furnace burning producer gas, specifically a kind of novel glass melting furnaces producer gas carrying method and device thereof.
Background technology
Adopt producer gas to be widely used in as the thermal storage type glass melting furnaces of fuel glassworks such as producing sheet glass, container glass, Glass tubing.These glass melter throughput difference are very large, and minimum day fusing amount only has several tons, and maximum can arrive 800～900 tons.At present, the thermal storage type glass melting furnaces of producer gas are most adopts traditional bell-jar coal gas exchanger to carry out the commutation of main flue coal gas.Coal gas utilizes pipeline to deliver to combined workshop from gas station, is introduced into bell-jar coal gas exchanger.If horse shoe flame melting furnaces, coal gas just directly enters the gas regenerator of respective side by minute flue, if Horizontal flame melting furnace, coal gas enters the by-pass flue of each port by reallocation after dividing flue, and then enters corresponding gas regenerator.
Bell-jar coal gas exchanger is come from external introduction from eighties of last century mid-term, and along with the development of melting furnaces scale and level of control these years, bell-jar coal gas exchanger is also upgraded on original basis.Bell-jar coal gas exchanger is comprised of parts such as outer cover, base, bell jar, lever system, rocker arrangement, pinch roller system, electrical control and counterweights.
Traditional bell-jar coal gas exchanger is three venting holes, when affecting chain to pass through pinch roller system, drive unit drives rocker arrangement, make outer four connecting rods drive two transmission shafts on base, thereby interior four connecting rods are rotated simultaneously, this clock mask also completes thereupon and rises and move horizontally, complete the conversion of bell jar position, make bell jar become another working position from a working position, with this, realize interchanger commutation effect.Coal gas is entered in outer cover by upper entrance, and bell jar covers one of them venting hole of base intermediate exhaust hole and both sides; With being filled with water in base, make bell jar and outer cover exocoel and bore seal, therefore form two paths.Article one, by a coal gas path that the venting hole not covering forms on the base of gas entry and outer cover inner chamber, the flue gas path that another is comprised of two venting holes that are covered on bell jar inner chamber and chassis.Now coal gas enters glass melter by coal gas flue, and in kiln, flue gas is discharged flue through flue gas path.Bell jar commutates once at regular intervals, forms new coal gas and flue gas path, makes coal gas and flue gas send into and discharge in kiln by this program.
Adopt the melting furnaces of traditional bell-jar coal gas exchanger to carry out in coal gas handoff procedure, bell jar is from a side direction opposite side transition period, under bell jar along leaving water front cover time, must have coal gas and enter three venting holes simultaneously, this has just caused a certain amount of coal gas to be blended in the mobile flue gas of chimney.In addition, before coal gas commutation, the coal gas of all advancing abrim in from coal gas exchanger to the long long-channel the ejiction opening of gas regenerator, along with melting furnaces change the startup of fiery program, coal gas of these burnings that are not able to do in time are reversed end for end with flue gas to chimney diffluence.If above-mentioned two portions coal gas is mixed to form explosion gas mutually with the air of the flue that bleeds, will form in the fullness of time flue and " blow out " accident, this phenomenon seems particularly serious at large glass production line, the consequence causing is more severe, slight meeting affects glass quality, reduce glass output, serious meeting affects personnel and property safety.Ju Mou company reflection, blows out accident each time, all can make glass finished-product rate be reduced to 45% left and right by 90% left and right, and impact is for four, five days, has seriously reduced glass output.The accident of " blowing out " is in addition not expected, and when who can put once if also not knowing, production operation and managerial personnel are therefore all day long on tenterhooks, wish very much an excellent plan and go to address this problem.
For this present situation, the way adopting be at present mostly at middle flue coal gas and air intersection point one naked light, the coal gas leaking into centre flue is as far as possible in an organized way burnt.Both having there is potential safety hazard in this way, increases the possibility that industrial accident occurs, and greatly wastes again fuel, increases production cost, also can cause environmental pollution to a certain degree simultaneously.
In addition,, in traditional producer gas glass melter coal gas carrying method, coal gas enters coal gas flue from interchanger, then to each port, divides timing, lacks regulating measure flexibly.Can only regulate indirectly, roughly coal gas amount by the manual flashboard on each coal gas branch flue at present.The effect of coal gas branch flue flashboard is mainly to regulate each port because demand is different, the equal factor of regenerator jam situation forms different flue gas drafts, and therefore with this flashboard, taking into account adjusting coal gas is to be difficult to accurately control melting furnace temperature.
Large-scale horizontal-flame glass melting furnace should be set up accurate temperature schedule according to the heat absorption situation of the different sections of melting furnaces, front end raw material district and hot spot region thermal load need large, froth zone heat absorption is bad, even if how input fuel is also waste, foot couple port is in order to regulate clarifying area temperature, and thermal load needs very little.Only, according to actual demand and rule dispensing fuel, could maximum bring into play the usefulness of fuel, otherwise all can produce waste, increase the pollution to environment simultaneously.
Therefore, need to be for adopting producer gas to do the thermal storage type glass melting furnaces of fuel, particularly large-scale many ports cross flame thermal storage type glass melting furnaces, a set of brand-new conveying coal gas of invention and the method for corresponding side flue gas.
Summary of the invention
