Abstract
The invention discloses a kind of carbon open roasting furnace used for fathering and making use of asphalt fume. It includes multiple furnace chambers, which are divided operation furnace chambers and non-operation furnace chambers, and the operation furnaces are divided low-temperature operation furnace chambers and high-temperature operation furnace chambers. There are partition walls between the furnace chambers. The furnace chambers compose of carbonization chambers and burning chambers ; the carbonization chambers are in the middle of two burning chambers ; there is plugging compound in the side wall of the carbonization chambers ; the roasted products are put in the plugging compound ; there are gas jets and connected mouths on the burning chambers , and there are gas-flow partition walls in the burning chambers ; its characteristics are : sealing the side wall of the burning chamber , setting gas skirt on the top of the low-temperature operation furnace chamber , connecting the low-temperature operation furnace chambers with fan by the funnel flue , connecting the fan and the chimney ; which not only protects environment but also low the cost and save the fuel. Its structure is simple and it is easy to operate.
Description
Technical field:
The present invention relates to the roaster technical field that carbon product is used, is a kind of charcoal element open roasting furnace of administering and utilizing glance coal specifically.
Background technology:
Carbon material is the important furnace charge of electrolytic aluminium and other smelting industry, annual consumption reaches millions of tons, carbon material as binding agent, produces a large amount of bitumen flue gas with pitch in roasting process, because carbonization chamber pressure is malleation, combustion chamber adjacent is a negative pressure, make the glance coal that evaporates enter the combustion chamber, to the diffluence of low temperature furnace chamber, discharge with flue with air-flow by the carbonization chamber side wall, cause serious environmental to pollute, wasted the valuable energy of high heating value simultaneously again; At present, the method for administering glance coal has following three kinds: first kind, and adopt static to remove the glance coal method, this method investment is big, and efficient is lower, and there is disaster hidden-trouble in the operating cost height; Second kind, with alumina powder absorption, this method investment and operating cost are very big, and general charcoal ink factory does not have aluminium oxide, can not use; The third adopts the combustion product gases counter-current, and promptly to high temperature, this method can not be utilized waste heat to flue gas from cryogenic flow, and exhaust gas temperature is 2-3 a times of normal circular furnace consume fuel more than 1200 ℃, wastes a large amount of fuel.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and provide a kind of energy to administer and utilize the charcoal element open roasting furnace of glance coal, mainly solve existing roaster and in roasting process, produce a large amount of bitumen flue gas, the problem that glance coal is discharged the after stain environment and wasted energy.
In order to achieve the above object, the present invention is achieved in that a kind of charcoal element open roasting furnace of administering and utilizing glance coal, it comprises a plurality of furnace chambers 1, divide operation furnace chamber and inoperative furnace chamber, the operation furnace chamber is divided into cold operation furnace chamber and hot operation furnace chamber, establish partition wall 11 between the furnace chamber 1, furnace chamber 1 is made up of carbonization chamber 2 and combustion chamber 3, carbonization chamber 2 is 3 centres two combustion chambers, establish inserts 4 in the side wall 6 of carbonization chamber 2, in the middle of inserts 4, establish baked article 5, on combustion chamber 3, establish jet for gas 7 and combustion chamber connected entrance 8, in combustion chamber 3, establish air-flow partition wall 12, its special character is side wall 6 sealings with carbonization chamber 2, establish gas skirt 10 above the carbonization chamber 2 of cold operation furnace chamber, the cold operation furnace chamber is connected with blower fan 14 by flue 13, and blower fan 14 is connected with chimney 15.
A kind of charcoal element open roasting furnace of administering and utilizing glance coal of the present invention, its described side wall 6 sealings with carbonization chamber 2 are that side wall 6 bodies are sealed air-tight, adopt air-locked refractory material and build by laying bricks or stones with refractory cement.
A kind of charcoal element open roasting furnace of administering and utilizing glance coal of the present invention, its described side wall 6 sealings with carbonization chamber 2 are to establish encapsulant 9 on side wall 6 inwalls; When encapsulant 9 is high-temperature fibre cement mortar float coat or high temperature glaze, fixing seal material 9 on the inwall of the side wall 6 of all carbonization chambers 2; When encapsulant 9 was sheet metal, only sheet metal was established in activity on the inwall of the side wall 6 of the carbonization chamber 2 of cold operation furnace chamber, extracts out when temperature reaches 600 ℃.
A kind of charcoal element open roasting furnace of administering and utilizing glance coal of the present invention, establish soft connecting tube 16 between its described gas skirt 10, establish appendix 17 near the gas skirt 10 above the carbonization chamber 2 of hot operation furnace chamber, appendix 17 is corresponding with the jet for gas 7 of the combustion chamber 3 of the hot operation furnace chamber that closes on.
Compared with the prior art a kind of charcoal element open roasting furnace of administering and utilizing glance coal of the present invention has outstanding substantive distinguishing features and marked improvement, 1, the side wall with carbonization chamber seals, stop glance coal to enter combustion chamber (quirk) effectively, make it enter gas skirt, collect fully, utilize high temperature furnace chamber negative pressure again, glance coal is sucked the high temperature furnace chamber enter burning, both protected environment, expensive cleaning equipment investment and operating cost have been saved again, make air-introduced machine shaft power economization simultaneously, save the operation fuel consumption; When 2, encapsulant is sheet metal, after 600 ℃ of extractions, recycle; 3, simple in structure, easy to operate.
