Description
Technical field
The present invention relates to the can-type calcine furnace in graphite electrode and anode production field; Particularly relate to can-type calcine furnace and forge the burnt cooling device in back, cause problems such as water resource waste in order to solve that the pressure that the can-type calcine furnace cold water jacket can bear is lower, the stokehold cooling water system can not be realized operation with closed ring, the cooling water evaporation amount is excessive.
Background technology
In the process of can-type calcine furnace calcined petroleum coke, at the petroleum coke more than 1000 ℃, discharge from the discharge gate that is located at the stove bottom through high-temperature calcination, temperature.Forge the burnt ingress of air in back for the high temperature that prevents to discharge out of the furnace and produce oxidation, generally all below discharging opening, be provided with 2～3 meters high cooling jackets.Through water jacket cooling to forge the back burnt, temperature is reduced to below 200 ℃, the back that discharges out of the furnace gets into forges the burnt induction system in back and transports.
The existing can-type calcine furnace of carbon industry, all be adopt the cooling jacket of jacket type to cool off the high temperature of discharging from the batch can bottom to forge the back burnt.The bottom of cooling jacket is provided with cold water inlet, is shape on an empty stomach in the chuck of water jacket, and the top of water jacket is provided with the hot water outlet pipe.Its water inlet pipe is connected with the feed pipe of cooling water recirculation system, outlet pipe then be located at the workshop in the uncovered tank of artesian water be connected mutually.Flow into the hot water of uncovered tank, cause the pond cooling of drying in the air outside the workshop, recycle then through the pipeline of trench bottom.This traditional cooling jacket; Shortcoming with following several respects: 1, the aquaporin of water jacket is a narrow square-section; The profile of whole water jacket also is trapezoidal shape, so it does not possess the ability of bearing big hydraulic pressure, so cooling water is circulated under closed circuit state; 2, in the cyclic process of cooling water, the splashing and the high temperature of stokehold of current when the hot water that the water jacket outlet pipe flows out gets into uncovered tank all can make the overflow and the evaporation loss that cause recirculated water, and then cause the long-term waste of water resource; 3, owing to the capacity limit of uncovered tank, when Jiao's cooling effect is bad after unusually, just forging appears in water temperature, can't adjust through the cooling water flow that increases in the water jacket; 4, cooling water flow can not be adjusted increase, cooling jacket high temperature is burnt leak, and severe patient can force whole pot type burner blowing out maintenance, has both reduced the production capacity of stove, can be had a negative impact the service life of stove again; 5, the water jacket cooling effect is bad, also can cause forging the burnt discharge temperature height in back, and the generation oxidation that discharges out of the furnace causes the back charred ashes part of forging of too high scaling loss to increase.
Summary of the invention
The present invention is exactly to provide a kind of can-type calcine furnace to forge the burnt cooling device in back in order to address the above problem, traditional cooling jacket bearing capacity closed cycle, cooling water overflow and evaporation loss poor, that can not realize cooling water are big to solve, the serious waste water resource, can't adjust cooling water flow, cooling jacket be prone to burn the continuous production of leaking, being unfavorable for can-type calcine furnace, influence stove service life, be prone to cause forging the burnt discharge temperature in back raise, increase scaling loss, reduce forge after problem such as burnt quality.
Forge the burnt cooling device in back for reaching above-mentioned purpose can-type calcine furnace of the present invention; Comprise and forge the burnt cooling cylinder in back; Forge the burnt cooling cylinder in back and comprise epimere steel cooling cylinder and hypomere steel cooling cylinder, be provided with the epimere lower flange in the bottom of epimere steel cooling cylinder, the top of epimere steel cooling cylinder is provided with the epimere upper flange; The bottom of epimere steel cooling cylinder is provided with the epimere cooling water intake; Epimere steel cooling cylinder top be provided with the epimere cooling water outlet, be wound with top cooling water channel coil pipe on the epimere steel cooling cylinder outer wall, top cooling water channel coil pipe is communicated with epimere cooling water intake and epimere cooling water outlet; The top of hypomere steel cooling cylinder is provided with the hypomere upper flange; The bottom of hypomere steel cooling cylinder is provided with the hypomere lower flange, and the bottom of hypomere steel cooling cylinder is provided with the hypomere cooling water intake, and the top of hypomere steel cooling cylinder is provided with the hypomere cooling water outlet; Be wound with bottom cooling water channel coil pipe on the hypomere steel cooling cylinder outer wall, bottom cooling water channel coil pipe is communicated with hypomere cooling water intake and hypomere cooling water outlet.
The steel plate gauge scope of described epimere steel cooling cylinder and hypomere steel cooling cylinder barrel is 2～15mm.
The number of bolt hole scope of described epimere upper flange and hypomere upper flange is 8～60, and the gauge scope is 5～45mm.
The number of bolt hole scope of described epimere lower flange and hypomere lower flange is 8～24, and the gauge scope is 5～45mm.
Described top cooling water channel coil pipe and bottom cooling water channel coil pipe are the steel coil pipe, and the cross section is semicircle or trapezoidal.
The radius of described top cooling water channel coil pipe and bottom cooling water channel coil pipe or height dimension scope are 15～100mm, and a pipe segmentum intercalaris carpenters square cun scope is 30～200mm.
Advantageous effect of the present invention:
1, because cooling water is in the cooling water channel coil pipe, to flow, and this tubulose water route has very big withstand voltage effect, therefore can realize the closed cycle of cooling water system.
2, can avoid cooling water splashing and evaporation loss under uncovered tank situation, help the water resource of saves valuable.
3, can adjust the cooling water flow that strengthens in the cooling device at any time, under any circumstance all can guarantee forging the burnt good cooling effect in back, the burnt quality in back is forged in the prolongation and the raising that help stove service life.
