The reduction and distillation furnace can heat the reduction and distillation pot by sections and forcibly cool the reduction and distillation pot and has good heating and cooling control effect so as to effectively improve the quality and the capacity of products. The reduction and distillation furnace has simple structure, convenient operation, stable use performance, long service life, high electrical heat energy utilization rate and low operation and maintenance cost and is particularly suitable for the production of titanium sponges.
Description
Technical field
The present invention relates to a kind of titanium sponge production unit, particularly a kind of reduction and distillation furnace.
Background technology
At present, the titanium sponge production technique is to utilize Mg liquid with TiCl
4In Ti restore, require the reaction surface temperature to be lower than 1000 ℃.This reaction is finished in the reduction distillation jar, and the adjusting of temperature then needs to utilize the reduction and distillation furnace of reduction distillation jar periphery to realize.Because this reduction reaction is thermopositive reaction, it is overheated that the reaction surface temperature is easy to, thereby reduction and distillation furnace will be considered this place is cooled off.The mode of available technology adopting air naturally cooling is cooled off, and promptly stays in the conversion zone position and establishes some inlet mouths and air outlet, and general inlet mouth is following, and the air outlet utilizes the chimneyeffect of hot flue gas to cool off last.The defective of this structure is: 1, cooling air adopts the naturally cooling mode, and cooling performance is bad, and superheating phenomenon usually takes place, and makes the reduction tank skin the more wall titanium of climbing occur, and influences quality product; 2, for the needs of sealing, inlet and outlet can not be provided with too much, causes same horizontal plane internal cooling effect inhomogeneous, influences quality product; 3, because reduction reaction is to carry out at the interface of two kinds of liquid, along with the carrying out of reaction, this reaction surface rises gradually, thus the electric heater that requires conversion zone to arrange cut apart careful as far as possible, change requirement with adaptive temperature, generally all compare roughly but prior art adds thermal control; 4, because existing heating unit can not carry out the power adjustment, can not adapt to the requirement at the frequent position of some temperature variation.
Summary of the invention
The invention provides a kind of reduction and distillation furnace simple in structure, can heat and force the segmentation of reduction distillation jar and cool off, can effectively improve the quality of products and production capacity, overcome deficiency of the prior art.
Technical scheme of the present invention is: it comprises the furnace shell that liner is installed, and furnace shell inside is equipped with the reduction distillation jar, and furnace shell is connected with the collection air port and the cloth air port of layering setting from top to bottom; Liner inwall layering from top to bottom is provided with heating unit.
Aforesaid collection air port is connected with air collecting box, and air collecting box is provided with air outlet.
Aforesaid every layer of cloth air port is connected with cloth bellows, and the cloth bellows are provided with blast inlet.
Aforesaid air outlet links to each other with induced draft fan.
Aforesaid blast inlet is rapidly opened and closed interface.
Aforesaid furnace shell is connected with vacuum-pumping tube.
Aforesaid liner is provided with 40～80 layers from top to bottom and puts a brick, and heating unit is arranged on to be put on the brick.
Aforesaid cloth air port is positioned at below furnace shell middle part, the collection air port, is divided into 1～5 layer; Every layer is provided with 4～16 cloth air ports, along circumferential uniform distribution.
The lead bushing of aforesaid heating unit passes liner and is connected with furnace shell.
Aforesaid liner inwall is provided with retaining jar brick.
Can also connect the vision slit pipe on the furnace shell of this reduction and distillation furnace, heating unit can be provided with according to furnace roof section, air-out zone, air intake zone, reactor hypomere, furnace bottom area, additional zone, the independent control of grouping, power regulation can also be carried out in wherein air-out zone and air intake zone; Heating unit adopts double star and and star connection respectively according to each group power difference.
Compared with prior art, the present invention can to the segmentation of reduction distillation jar heat and force the cooling, heating and cooling control is effective, can effectively improve the quality of products and production capacity, and it is simple in structure, easy to operate, use properties is stable, the life-span is long, electrical heat energy utilization ratio height, and operation and maintenance cost are low.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Embodiment
Embodiments of the invention:
In furnace shell 1 inside reduction distillation jar 11 is installed, a vacuum-pumping tube 4 is welded in the bottom, and side is equipped with liner 2 within it, be equipped with 40～80 layers on the liner 2 and put a brick 13, heating unit 3 is fixed on to be put on the brick 13, the lead bushing of heating unit 3 passes liner 2 and is installed on the furnace shell 1, and three ring retaining jar bricks 12 also are housed on the liner 2, prevents that reduction distillation jar 11 from contacting with heating unit 3.
Also be welded with 1～5 layer independently cloth air port 8 (every number of plies amount is 4～16) on the furnace shell 1, cloth air port 8 is positioned at stove middle part conversion zone, and cloth bellows 9 are positioned at 8 outsides, cloth air port, are divided into independently several layers corresponding to cloth air port 8, respectively with cloth air port 8 and furnace shell 1 welding; Cloth bellows 9 utilize the cylindrical shell of furnace shell 1 as inwall, its horizontal ring flat-plate and furnace shell 1 welding and load-bearing, and blast inlet 10 is left in cloth bellows 9 outsides, blast inlet 10 each layer independence, every layer of 2 symmetrical distribution are rapidly opened and closed interface, directly communicate with atmosphere.
At reduction phase, when reduction distillation jar 11 reaction surfaces were cooled off, freezing air entered from that one deck blast inlet 10 of reduction reaction face, through cloth bellows 9 and cloth air port 8, circumferentially evenly directly washed away tank skin, took away the reduction reaction heat release; Simultaneously freezing air sharply is heated as high-temperature gas, makes progress along tank skin then, is pooled to air collecting box 6 through circumferential equally distributed collection air port 5, and is drawn by induced draft fan through air outlet 7.Along with reaction surface moves up, open last layer blast inlet 10, one deck blast inlet 10 before closing continues reaction surface is cooled off.If reduction distillation jar 11 somewhere temperature do not reach design temperature, can improve by heating unit 3 heating that start this place.In the distillation stage, all inlet and outlet 7 is airtight, is taken out by vacuum-pumping tube 4 and draws vacuum.
Certainly, can also connect the vision slit pipe on the furnace shell 1 of reduction and distillation furnace, heating unit 3 can be provided with according to furnace roof section, air-out zone, air intake zone, reactor hypomere, furnace bottom area, additional zone, and grouping is independent to be controlled, and power regulation can also be carried out in wherein air-out zone and air intake zone; Heating unit 3 adopts double star and and star connection respectively according to each group power difference.Such improvement all drops within protection scope of the present invention.
