Description
Technical field
The utility model relates to a kind of waste heat of coke oven crude gas and utilizes equipment, belongs to waste heat of coke oven crude gas recovery and utilization technology field.
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 tedge, by bilayer sleeve, import and the outlet of bilayer sleeve on the tedge housing that interior pipe and outer tube are formed, form enclosure space between the outer tube of bilayer sleeve and the interior pipe, this enclosure space is called interlayer; Bilayer sleeve passes the tedge housing by import and gets in the tedge; In tedge, arranging and pass the tedge housing and be outlet, is the processing medium that flows in the interior pipe of bilayer sleeve, places heat-conducting medium in the interlayer; The high temperature raw coke oven gas is passed to heat-conducting medium to heat through outer tube in the coke oven coke oven uprising tube, and heat-conducting medium is passed to processing medium to heat through interior pipe.
Described bilayer sleeve is arranged at tedge inside spin shape.
Described processing medium is a water, and heat-conducting medium is that gas-solid two is combined to material, liquid-solid two-phase synthetic material, solid phase synthetic material.
The coal oven dithio-gas of high temperature flows in the tedge during work; Upwards flow in the limit; Tedge is flowed out at last through the heat-conducting medium heat exchange in outer tube and the interlayer in the limit, and the heat-conducting medium that absorbs the raw coke oven gas waste heat is passed to the processing medium in the interior pipe to heat through interior pipe; In flowing into by import in the pipe processing medium heat absorption back flow out by outlet, remove subsequent processing.
The position that the utility model is recycled waste heat of coke oven crude gas is between coke oven top 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, and the temperature of processing medium is raise or generation steam, the most important thing is to adopt the method that increases one deck outer tube; The heat-transfer area that has successfully solved heat-transfer area bonding tar or floccule obstruction and interior pipe damages, and processing medium (like water) leaks the problem of not going into the carbonization chamber, need explain here: we know that heat is conducted to low by height automatically; In the processing medium diabatic process, the raw coke oven gas temperature is higher than the outer tube temperature at raw coke oven gas, and the outer tube temperature is higher than the heat-conducting medium temperature; Pipe temperature in the heat-conducting medium temperature is higher than; Interior pipe temperature is higher than the processing medium temperature, so newly-increased outer tube temperature is managed temperature in just being higher than, owing to the outer tube temperature has improved; Tar can't condensation be bonded in outer tube-surface in the raw coke oven gas, forms floccule and has stopped up; Pipe in newly-increased outer tube spatially contains fully, interior pipe heat-transfer area damages processing medium and can only leak in people's interlayer, has but entered not the carbonization chamber, so safe and reliable; Installation and Debugging put into operation, do not influence the ordinary production of coke oven.
Adopt the utility model; For preventing raw coke oven gas outlet temperature problem of too,, adopt the technical measures that increase heat-transfer area effectively all recovery rationally of waste heat; Comprise: increase the arrangement length of bilayer sleeve in tedge, the bilayer sleeve surface is provided with fin 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.
