Abstract
The utility model discloses a tank type calcining furnace for preparing calcined petroleum coke, comprising a material tank and a material discharging pipe connected below the material tank. The tank type calcining furnace for preparing calcined petroleum coke is characterized in that an exhaust tube is connected on the material discharging pipe, and an air extractor is connected on the exhaust tube. By adopting the tank type calcining furnace, raw material consumption can be reduced, and circulating cooling water quantity can be reduced, so as to have effect of saving energy, reducing CO2 emission and protecting environment.
Description
Technical field
The utility model relates to a kind of can-type calcine furnace that is used to prepare after-smithing petroleum coke, especially relates to a kind ofly can blocking the can-type calcine furnace that enters air from discharge gate.
Background technology
At carbon industry, preparation anode material---one of means of after-smithing petroleum coke are to adopt can-type calcine furnace calcined petroleum coke, the about 3500Kt/a of its production capacity at present.Though finishing the raw material that heat energy is passed in the jar in the existing quirk of can-type calcine furnace volatile combustion outside jar heats up, but because the pot furnace body is vertical, top has volatile matter eliminating passage to link to each other with quirk and smokestack, in tank body, form negative pressure, tank body cooling section discharge part directly is discharged on the handling equipment, do not have tightness system with the handling equipment connection portion, under suction function, some air are sucked tank body, cause a jar interior pyrocarbon raw material refinery coke of 3-4% still to be arranged by scaling loss.Particularly, when discharge, because smokestack effect and hot transpiration, the carbon reaction of the air in discharge gate enters stove the about 300-500 of cooling section temperature ℃ zone and refinery coke generates CO
2, CO in the up process
2Continue reaction with carbon and generate CO, enter the reaction of quirk and oxygen at last from top and form CO
2Enter smokestack.This process increases cooling water amount with fine carbon raw materials consume in cooling section burning heat release, forms greenhouse gases at last and discharges, and being one had not only increased cost but also environmentally hazardous bad process.
The utility model content
In view of this, the purpose of this utility model provides a kind of can-type calcine furnace that is used to prepare after-smithing petroleum coke, and this calcining furnace can be blocked the can-type calcine furnace that enters air from discharge gate.
Above-mentioned purpose realizes by following proposal:
A kind of can-type calcine furnace that is used to prepare after-smithing petroleum coke, described can-type calcine furnace comprise batch can and are connected the drainage conduit of batch can below, it is characterized in that, be connected with extraction pipe on described drainage conduit, and connect air extractor on described extraction pipe.
According to above-mentioned can-type calcine furnace, it is characterized in that described batch can is a plurality of, and on each drainage conduit below a plurality of batch cans, all be connected with extraction pipe.
According to above-mentioned can-type calcine furnace, it is characterized in that each drainage conduit of described a plurality of batch cans below is aggregated into one and gathers pipe, is connected with extraction pipe on the pipe in described gathering.
Use this can-type calcine furnace can cut down the consumption of raw materials and reduce the recirculated cooling water amount, thereby can obtain energy-conservation, as to reduce CO2 discharging and protection environment effect.
Description of drawings
Fig. 1 is the structural representation of can-type calcine furnace of the present utility model.
Embodiment
Referring to Fig. 1, can-type calcine furnace comprises at least one batch can 1 (shown in Fig. 1 being two), all is connected with drainage conduit 3 below each batch can 1, and drainage conduit 3 is connected with batch can 1 by blow-off valve 2, and every drainage conduit 3 converges to and gathers pipe 4.In drainage conduit 3 or gather and connect extraction pipe 5 on the pipe 4, connect the air extractor (not shown in figure 1) on the extraction pipe 5.Can only on drainage conduit 3, connect extraction pipe 5, perhaps only gather connection extraction pipe 5 on the pipe 4, can also all be connected extraction pipe 5 with gathering to manage on 4 in drainage conduit 3.
When using calcining furnace discharge of the present utility model, when opening blow-off valve 2, start air extractor, in the drainage conduit of extraction pipe present position, occupy the negative pressure of generation-10-0 millimeter water column in the zone of whole section, just the air of suction drainage conduit 3 effectively can be tackled.Rate of air sucked in required can be determined according to the drainage conduit sectional dimension of different capacity pot-type stoves.General every jar less than 1 cubic metre/hour.
Use calcining furnace of the present utility model to make to enter the air in the retort effectively to be contained, facts have proved and to make the carbonaceous scaling loss be reduced to 1-0.5% from 3-4%, reduce material loss 2-3.5%, the back material of forging per ton reduces the recirculated cooling water consumption: the 36-54 ton, reduce Carbon emission: the 27.5-47 kilogram.
Claims (3)
1. can-type calcine furnace for preparing after-smithing petroleum coke, described can-type calcine furnace comprise batch can and are connected the drainage conduit of batch can below, it is characterized in that, be connected with extraction pipe on described drainage conduit, and connect air extractor on described extraction pipe.
2. can-type calcine furnace according to claim 1 is characterized in that, described batch can is a plurality of, and all is connected with extraction pipe on each drainage conduit below a plurality of batch cans.
3. can-type calcine furnace according to claim 2 is characterized in that, each drainage conduit of described a plurality of batch cans below is aggregated into one and gathers pipe, is connected with extraction pipe on the pipe in described gathering.
