Abstract
The utility model relates to a pot -type furnace especially relates to the pot -type furnace that the plain graphitization material of positive pole for the aluminium, negative pole, electrode and charcoal was produced to the plain trade of charcoal. Including cooling channel and pot -type furnace bottom flame path, by following structure composing: cooling channel is the multilayer, and the cooling channel's of the bottom import is equipped with imported arm -tie, and upper and lower adjacent cooling channel communicates with each other from beginning to end, does not have preheated air to erect in the front on wall and the back wall and says. The utility model discloses the passageway can improve pot -type furnace and to volatile matter content's adaptability, both strengthen original cooling effect, has still simplified the preheated air passageway, has retrieved preheated air's heat simultaneously, improves the furnace thermal efficiency.
Description
Technical field
The utility model relates to a kind of pot furnace, particularly relates to the pot furnace that carbon industry produces aluminium anode, negative electrode, electrode and charcoal element graphitized material.
Background technology
Can-type calcine furnace is low mainly due to carbon burnt loss, production process and constant product quality well gradually at calcining petroleum coke market dominate, particularly aluminium anode calcining workshop section.But in recent years, along with the lifting of upstream chemical oil refining technology, as the refinery coke deterioration of byproduct, volatile content wherein rises gradually, for pot furnace, the increase of volatile content means the total heat revenue growth of stove, from heat calculation result and on-the-spot practical operation situation, the increase of volatile content can cause quirk to be in superheat state, shortens furnace campaign.Therefore need reduction stove heat income to a certain degree, way conventional at present cancels furnace bottom preheated air, adopts freezing air combustion-supporting, fire path temperature can be made so at least to reduce by more than 100 DEG C.Preheated air flows through the cooling channel bottom quirk, according to current pot furnace structure, if preheated air does not enter quirk, then outer can drain into workshop, make workshop overheated, degradation manipulation environment.And cooling channel also has a critical function, suitably reduce the high-temperature material temperature entering watercooling jacket exactly, prevent the crossbeam of furnace binding overheated.Therefore need to improve original furnace bottom cooling channel.
Summary of the invention
The utility model is a kind of pot furnace proposed to solve the problem, and object had both ensured the function at the bottom of original cool furnace, ensures support steel beam stress, is used by the atmospheric heat of preheating again, improves furnace thermal efficiency.
For reaching above-mentioned purpose the utility model pot furnace, comprise cooling channel and pot furnace bottom quirk, by following Structure composing: cooling channel is multilayer, the import of the cooling channel of the lowest layer is provided with import arm-tie, neighbouring cooling channel head and the tail communicate, and front wall and rear wall do not have preheated air to erect.
Cooling channel is divided into three layers, is built by laying bricks or stones form by hollow refractory brick.
Cooling channel sucks air from rear wall, and after turning back to front wall, wall turns back front wall again, enters set and is communicated with flue and discharges.
Described import arm-tie is arranged on rear wall channel entrance position.
The utility model advantageous effect:
The utility model passage can improve the adaptability of pot furnace to volatile content, has both enhanced original cooling performance, and also simplify preheated air passage, has reclaimed the heat of preheated air simultaneously, improves furnace thermal efficiency.
Accompanying drawing explanation
Fig. 1 is furnace bottom cooling channel of the present utility model schematic diagram.
In figure: 1, pot furnace bottom quirk; 2, cooling channel; 3, import arm-tie; 4, set is communicated with flue.
Embodiment
Below embodiment of the present utility model is described in detail by reference to the accompanying drawings, but protection domain of the present utility model not limit by embodiment.
Pot furnace as shown in the figure, comprise cooling channel 2 and be communicated with flue 4 with set, cooling channel 2 is multilayer, and the import of the cooling channel 2 of the lowest layer is provided with import arm-tie 3, and neighbouring cooling channel 2 head and the tail communicate, and front wall and rear wall do not have preheated air to erect.
Cooling channel 2 is divided into three layers, is built by laying bricks or stones form by hollow refractory brick.
Cooling channel 2 sucks air from rear wall, and after turning back to front wall, wall turns back front wall again, and enter set and be communicated with flue 4 and discharge, do not enter pot furnace bottom quirk 1, power comes from negative pressure system.
Import arm-tie 3 is arranged on rear wall channel entrance position.The air capacity entered is regulated by channel entrance arm-tie 3.
Claims (4)
1. pot furnace, comprise cooling channel and pot furnace bottom quirk, it is characterized in that by following Structure composing: cooling channel is multilayer, the import of the cooling channel of the lowest layer is provided with import arm-tie, neighbouring cooling channel head and the tail communicate, and front wall and rear wall do not have preheated air to erect.
2. pot furnace according to claim 1, is characterized in that cooling channel is divided into three layers, is built by laying bricks or stones form by hollow refractory brick.
3. pot furnace according to claim 2, is characterized in that cooling channel sucks air from rear wall, and after turning back to front wall, wall turns back front wall again, enters set and is communicated with flue and discharges.
4. pot furnace according to claim 1, is characterized in that described import arm-tie is arranged on rear wall channel entrance position.
