Abstract

The utility model relates to an eight-pot nine-layer calcined furnace and comprises two rows of vertical coal-calcined pots (4), a heating fire (5) trail that is arranged surrounding the coal-calcined pots, a flue (12) and a chimney (13) in folded way; the top of the coal-calcined pot is directly communicated with the bottom of the pot; the top of the coal-calcined pot is provided with a material feeding funnel (1) and the bottom is provided with a discharging funnel (6). The utility model is characterized in that every row of the coal-calcined pots is provided with four coal-calcined pots, which is totaled in eight; the coal-calcined pot is arranged on the side wall, which is provided with a volatilization exhaustion port (3), at the top layer of the heating fire trail; the flue (12), (16) is led from the bottom of the heating fire trail. Since the furnace structure is changed, the service life of the utility model can reach ten years, which prevents from being repaired less than three years of the prior art; the temperature inside the furnace is uniform, and the temperature in the high-temperature area can be kept at 1200 DEG C to 1350 DEG C, and the temperature is almost the same from the first layer to the eighth layer; with the same capital investment, the output is increased from 10 to 12 tons per day of the traditional six-pot furnace to 20 tons per day.

Description

8-box 9-layer high-temp calciner

Technical field

The invention belongs to the structure of Industrial Stoves, particularly a kind of eight jars of nine layers of calcining furnaces.

Background technology

The carbon calciner of present domestic use is that the seventies is from Japan, the technology that the former Soviet Union introduces, the type of furnace is 6 jars three layers, change 6 jars of 5 layers of quirks after the eighties into, change 6 jars of 7 layers of quirks after 95 years into, upgrade to 6 jars of 9 layers of quirks after 99 years, the physical and chemical index of carbon element, the seventies, fugitive constituent can only be forged row 2%, and resistivity is 1600 ohm, and fugitive constituent can be forged row 2% after the eighties to the nineties, 95 years so far, bring up to 0.9%-1%, resistivity is about 1100 ohm, and comparing with electric forge furnace still has big gap, adopt electric forge furnace, fugitive constituent reaches 0.6%, and resistivity drops to about 800 ohm, but the cost of electric forge furnace is too high, power consumption is too big, causes production cost very high.

Chinese patent " carbon furnace " (application number 00247722.X) discloses a kind of technical scheme, this scheme remains typical six jar structures, and the trend of quirk is not reasonable especially, and furnace temperature is even inadequately, the output of carbon element and quality can't be compared with electric forge furnace, and waste heat can not get abundant recovery, utilization.

Summary of the invention

The purpose of this invention is to provide a kind of make full use of waste heat, simple in structure, invest that output is big, quality reaches eight jars of nine layers of calcining furnaces that electricity is forged level on an equal basis, the present invention realizes by following scheme:

Eight jars of nine layers of calcining furnaces, comprise two row's vertical calcined coal container (4) and reciprocally arrayed heating quirk (5), flue (12) and chimneys (13) on every side, calcined coal container is straight-through the end of to by the top, feed hopper (1) is arranged at its top, discharge bucket (6) is arranged at the bottom, and the every row of calcined coal container (4) has four, totally eight, calcined coal container (13) is on the side wall of the top layer of heating quirk and has fugitive constituent outlet (3), and the bottom of heating quirk is drawn smokejack (12), (16);

On the vertical quirk in the front and back of above-mentioned heating quirk, be provided with plate (14), (15) of adjusting flow;

Above-mentioned quirk, the used furnace building material of calcined coal container are resistant to elevated temperatures primary and secondary silica brick;

Be connected to waste heat boiler (11) on the above-mentioned flue (16).

Above-mentioned waste heat boiler produces the activation steam of steam as Activated Carbon Production.

Effect of the present invention is embodied in the following aspects:

(1) owing to change furnace binding, reach 10 years service life of the present invention, avoided prior art less than 3 years will overhaul situation take place;

(2) temperature equalization in the stove of the present invention, the high-temperature region can keep 1200-1350 ℃, and one deck to eight layer temperature difference is approaching;

(3) under the equal investment, output is brought up to more than 20 ton per days by the 10-12 ton per day of past six pan furnace;

(4) need not external heat source, being warming up to 900 ℃ behind the some stove just can seal the external firing stove, keep furnace temperature by the fugitive constituent burning of forging out fully, waste heat still has affluence, and the waste heat boiler that can drive one 2.5 tons is produced steam, and steam can be used for the activation of active carbon, reduce the energy consumption of Activated Carbon Production greatly, because sufficient combustion, the blackness of exhaustion of discharge is reduced to the Lin Keman blackness and is lower than 1 grade, and production environment is thoroughly improved.

(5) charcoal quality amount has substantive the raising, and fugitive constituent is reduced to 0.6% (weight), and resistivity is reduced to 800 ohm, has reached the level of electric forge furnace, has changed the history that general forge furnace can only be produced low-and-medium-grade products.

The specific embodiment

Embodiment a: specific embodiment of the present utility model such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, this stove has a square furnace (2), body of heater has two-layer, internal layer is a heat-insulation layer, (2-1), skin is to be provided with the vertical calcined coal container (4) of two rows in brick layer (2-2) body of heater from top to bottom, around it is quirk (5), calcined coal container (4) has parallel two groups, have eight, loading hopper (1) is equipped with at its top, discharge bucket (6) is arranged at the bottom, there is a vertical partition wall (10) at the middle part in the body of heater (2), about calcined coal container (4) and quirk be divided into two groups, separation wall (17) is arranged between every group of calcined coal container, from vertically, quirk being interspersed and the vertical quirks in front and back (19) in the body of heater by horizontal partition wall (18), (20) the formation quirk of turning back from top to bottom, the quirk of turning back in this example has nine layers, at top layer quirk place, have fugitive constituent outlet (3) on the calcined coal container sidewall, the fugitive constituent of material is discharged thus in the calcined coal container, in the quirk internal combustion, through the quirk of turning back to the bottom quirk, waste gas discharges out of the furnace thus, in this example, waste gas enters a waste heat boiler (11) by flue (16), the heating water generates steam, insert chimney (13) row to atmosphere through flue (21) again, flue (16) is provided with a gate valve (8), when waste heat boiler need overhaul, this valve can cut out, waste gas enters chimney by another flue (12) and valve (12), in this example, vertically be provided with several peep holes (22) on the quirk, be useful on the plate (14) of control air velocity in the hole, (15), capping (23) is arranged outside the hole, coal enters from loading hopper, the blow-on stage provides thermal source by the combustion furnace of being located at bottom of furnace body (7), treat that furnace temperature reaches 900 ℃ after, the burning of fugitive constituent can guarantee the furnace temperature requirement, just the combustion chamber can be sealed, the fugitive constituent of overflowing in the coal process from top to bottom just can be sintered into finished product with himself in the quirk internal combustion.
