Description

Drawer type cooling device

Technical field

The utility model is related to the High-temperature mineral powders of the dry quenched coke powder reclaiming device of field of metallurgy, sintering machine deduster to return Receiving apparatus, as in primary dedusting by high-temperature particle, dust collecting system, by high-temperature particle and dust by collecting in drawer It is being discharged after cooling in formula water cooling collection device, is being related specifically to a kind of lime-ash heat exchange cooling device.

Background technology

In the recycling of dry coke quenching coke powder and sintering machine duster system, high temperature coke powder in recycling cool down cold But it handles, and dry quenching water-cooling sleeve cooler is exactly the dedicated unit that cooling treatment is carried out to high temperature coke powder.It is existing dry to put out Burnt water cold sleeve cooler mainly include cooler ontology, collected overhead dry cooled coke powder single tine, be located at cooler it is intrinsic Inside and outside casing, water inlet, drainage system and the ash discharge format valve positioned at cooler body bottom portion；From water inlet, drainage system to set Cooling water, discharge high-temperature water are constantly injected in managing, by progress heat exchange between cooling water and high temperature coke powder to reach cooling Purpose.Existing dry quenching water-cooling sleeve, such as authorize Publication No. CN201439515 U, CN202157052 U, CN202226811 U, CN205115372 U, CN205156633 U, CN205398545 U are to use outer sleeve and inner cylinder Being welded together by upper and lower blind plate, the chuck that outer sleeve inner wall and inner tank theca are formed, outer sleeve and inner cylinder lead to cooling water, Chuck is the cooling of high temperature coke powder and passing away.The whether normal good operation of water cold sleeve determines the height in disposable dust remover Can warm coke powder smoothly be discharged safely；Since water cold sleeve is washed away through high temperature coke powder for a long time, outer tube metal generates creep, pole Easy desoldering, welding position desoldering through high temperature corrosion, makes water cold sleeve internal leakage occur, the recirculated cooling water leaked out with The coke powder channel also resulted in water cold sleeve after coke powder mixing blocks, and need to shut down dry coke quenching equipment and wait for that coke powder is cold But water cold sleeve could be replaced after, it is same to influence the continuous operation of dry quenching system, and needed after water cold sleeve internal leakage pair Entire three layers of casing is replaced, and maintenance cost is higher, due to three-decker water cold sleeve own vol and weight compared with Greatly, disassembly and installation is more difficult；It is dismantled online very in high temperature and the internal circulated inert gas used simultaneously It is dangerous；The general bottom of water cold sleeve carries out ash discharge using Jameson scheme valve, since format valve uses one generally under negative pressure state As inleakage it is bigger, be easy to cause second of coke powder burning when air enters in closed container, aggravation metal generates compacted Become and damage, in addition it is hardened to be easy to cause coke powder in water cold sleeve for coke powder, and dismounting is also needed after coke powder is hardened and is cleared up, and one As dismounting water cold sleeve dismounting is primary needs 12 hours, while dismantling super large part object in high temperature and narrow operating space Product are to be in abnormally dangerous work.
