Background technology
At present; People have accumulated abundant UTILIZATION OF VESIDUAL HEAT IN technology at industrial circle, and the waste heat of coke oven crude gas utilization also is one of them, yet; In the background technology; Since coke enterprise used carbonization chamber method to fire coke, the waste heat of high temperature coke oven raw coke oven gas just failed effectively to utilize always in the tedge, can only waste heat with the cyclic ammonia water cooling.Someone is the processing medium water heat exchange in raw coke oven gas and the chuck, but heat-transfer surface bonding tar, floccule blockage problem occur, and after heat-transfer surface damaged, processing medium water leaked into that the carbonization chamber influences coke production in the chuck.In recent years, adopt hot pipe technique and conduction oil technology to carry out the waste heat of coke oven crude gas utilization, all can not long-period stable operation; Main cause is: these background technologies all do not overcome the difficulty of coke-stove gas heat exchange; When other partial fault of heat-exchange system quits work, carbonization chamber method, an oven coke has not been produced; Blowing out in short time halfway is so problems such as heat pipe booster, the overheated coking of conduction oil occur.Done detailed explanation in one piece of " waste heat recovery of coking raw coke oven gas is shouldered heavy responsibilities " article of being write by Feng Hengfu that these present situations were published on September 14th, 2010 " China Metalurgy ", this article comprises the content of three parts altogether: the one, and the necessity of coking raw coke oven gas UTILIZATION OF VESIDUAL HEAT IN; The 2nd, China's coking raw coke oven gas UTILIZATION OF VESIDUAL HEAT IN process; The 3rd, accelerate the research and development of coking raw coke oven gas heat recovery technology.This article is pointed out emphatically at the ending paragragh of second portion content: " coking raw coke oven gas heat recovery technology is in the nearly 30 years research course of China; its material, structure can not satisfy the field working conditions requirement; the low life-span of efficient is short; key technology does not break through, and does not still have ripe, reliable, stable big industrial applications instance so far ".
The utility model content
The utility model purpose provides a kind of waste heat of coke oven crude gas and utilizes equipment, makes heat-transfer surface not burn into bonding tar or floccule obstruction, and heating surface damages, and also not to the indoor leakage processing medium of carbonization (water), solves the problems referred to above that exist in the background technology.
The technical scheme of the utility model is:
A kind of waste heat of coke oven crude gas utilizes equipment; Comprise intermediate cylinder, inner core and urceolus, the inside and outside both sides of intermediate cylinder are respectively equipped with inner core and urceolus, chuck in constituting between inner core and the intermediate cylinder; Constitute external jacket between urceolus and the intermediate cylinder; The shared middle cylindrical shell of interior chuck and external jacket, the axial height of interior chuck is greater than the axial height of external jacket, and interior chuck blocks external jacket fully; Interior chuck falling heat-transfer medium, external jacket is full of processing medium, the direct and interior chuck heat exchange of high temperature raw coke oven gas, heat is given the processing medium in the external jacket again through the heat-conducting medium of interior chuck.
The top and bottom of said intermediate cylinder are provided with upper flange and lower flange, link with tedge bridge tube valve body, tedge base respectively; Interior chuck and external jacket are the closed cavity structure, and interior chuck cavity is provided with heat-conducting medium import and heat-conducting medium import export, and the external jacket cavity is provided with processing medium import and processing medium outlet.
The coal oven dithio-gas of high temperature flows in the inner core of tedge during work; Upwards flow in the limit; Inner core is flowed out in heat-conducting medium heat exchange in limit and the interior chuck cavity at last, and the heat-conducting medium that absorbs the raw coke oven gas waste heat is passed to the processing medium in the external jacket with heat through intermediate cylinder; External jacket processing medium heat absorption back is flowed out by outlet, removes subsequent processing.
The position that the utility model is recycled waste heat of coke oven crude gas is between furnace roof tedge base flange to tedge bridge tube valve flange, and the position of coke oven coke oven uprising tube exactly is specially adapted to the transformation of old coke oven.The heat that reclaims has finally passed to processing medium; The temperature of processing medium is raise or generation steam; The most important thing is to adopt the method that increases interior chuck; Successfully solved the problem of the heat-transfer area damage of heat-transfer area bonding tar or floccule obstruction and processing medium (like water), leaked and do not go into the carbonization chamber, safe and reliable; Installation and Debugging put into operation, do not influence the ordinary production of coke oven.
Adopt the utility model,,, adopt the technical measures that increase heat-transfer area effectively all recovery rationally of waste heat for preventing raw coke oven gas outlet temperature problem of too.For example: the heat transfer area that increases inner core and intermediate cylinder; Increase fin etc. in inner barrel, intermediate cylinder surface; Increase heat-conducting medium circulation canal etc.
The positive effect of the utility model is: make heat-transfer surface not corrode bonding tar or floccule obstruction; When heat-transfer surface damages; Processing medium can leak carbonizing chamber of coke oven; Have that energy-saving effect is outstanding, long-period stable operation, safe and reliable, characteristics such as maintenance and repair are easy, solved this area and thirsted for the technical problem that solves for a long time.
